They spend most of their time in the upper two levels of the canopy. It is currently classified as Endangered by the IUCN; and a second species, Daubentonia robusta, appears to have become extinct at some point within the last 1000 years. The genus Daubentonia was named after the French naturalist Louis-Jean-Marie Daubenton by his student, Étienne Geoffroy Saint-Hilaire, in 1795.

Daubentonia madagascariensis

Psychedelic substances, once the mainstay of counterculture, are steadily blending into mainstream recreational and therapeutic activities across North America. But are they safe?



A recent in-depth study offers some sobering new insights. The investigation reveals a worrying association between the use of hallucinogens - a category that includes substances such as psilocybin, LSD, DMT (Ayahuasca), and MDMA (Ecstasy) - and a heightened risk of developing schizophrenia.



The comprehensive study was conducted by researchers at ICES, The Ottawa Hospital, the Department of Family Medicine at the <a href="https://www.uottawa.ca/en" target="_blank" rel="noreferrer noopener">University of Ottawa</a>, and Bruyère Health Research Institute.



Although the positive therapeutic potential of psychedelics has garnered significant enthusiasm lately, the research team cautions that usually, such celebration outpaces thorough understanding of the associated risks.



<h2 class="wp-block-heading" id="h-psychedelic-use-and-schizophrenia">Psychedelic use and schizophrenia </h2>



The analytic foundation of the study relied on over a decade's health data of people aged 14 to 65 years living in Ontario, Canada. 



The researchers monitored changes in hallucinogen-related emergency department (ED) visits and ensuing <a href="https://www.earth.com/news/owning-a-cat-before-age-25-doubles-the-risk-of-schizophrenia/" target="_blank" rel="noreferrer noopener">schizophrenia</a> diagnosis rates.



The results were astonishing: Relative to the general population, an individual with a hallucinogen-related visit to the emergency department had a staggering 21-fold increase in the likelihood of developing schizophrenia.



Even after factoring in co-occurring substance use and <a href="https://www.earth.com/news/mental-health-crisis-half-of-the-worlds-population-will-be-affected-by-age-75/" target="_blank" rel="noreferrer noopener">mental health disorders</a>, the risk remained 3.5 times higher.



<h2 class="wp-block-heading" id="h-alarming-data-trends">Alarming data trends</h2>



The data, spanning from 2008 to 2021, also revealed another concerning trend. While the annual rates of ED visits associated with <a href="https://www.earth.com/news/cannabis-and-hallucinogen-use-are-at-historically-high-levels/" target="_blank" rel="noreferrer noopener">hallucinogen use</a> were stable between 2008 and 2012, they saw a sudden 86% spike in the period from 2013 to 2021.



Within three years of an ED visit involving hallucinogens, 4% of individuals were diagnosed with schizophrenia. 



In comparison, the diagnosis rate for the general population was a meager 0.15% within the same timeframe - a difference that equates to an alarming 21 times higher risk for the former group.



When stacked against the risk associated with alcohol and <a href="https://www.earth.com/news/high-potency-cannabis-use-linked-to-epigenetic-changes/" target="_blank" rel="noreferrer noopener">cannabis use</a>, hallucinogens still didn't fare well. 



Individuals with ED visits due to psychedelic use were at 4.7 and 1.5 times higher risk of schizophrenia, respectively, compared to alcohol and cannabis.



<h2 class="wp-block-heading" id="h-risks-of-psychedelic-use">Risks of psychedelic use</h2>



Despite the study’s potentially alarming findings, the study authors emphasized that their findings do not establish a causal link between hallucinogen use and schizophrenia and that much more information is needed about risks associated with different types and use patterns of hallucinogens.



“Our findings underscore a concerning link between hallucinogen use that requires care in the emergency room and increased risk of schizophrenia,” said Dr. Daniel Myran, a Canada Research Chair in Social Accountability at the University of Ottawa.



“While there is enormous enthusiasm for psychedelic-assisted therapy as a new mental health treatment, we need to remember how early and limited the data remains for both the benefits and the risks,” noted Myran.



This highlights the urgency for more studies and improved public health measures to better comprehend and mitigate these risks.



<h2 class="wp-block-heading" id="h-screening-and-monitoring">Screening and monitoring</h2>



In clinical trials of psychedelic-assisted psychotherapy, experts integrate safeguards like excluding individuals with a personal or family history of schizophrenia and close monitoring,.



However, the study authors warn about the potential risks of hallucinogen use outside of these controlled settings.



The study also highlights the need to identify those at higher risk of developing serious adverse events from hallucinogens, facilitating safe recruitment practices in future trials.



<h2 class="wp-block-heading" id="h-psychedelic-safety-in-clinical-settings">Psychedelic safety in clinical settings</h2>



The implications of this study are very critical both to public health and to policy development. As psychedelics become more accepted for therapeutic and recreational use, understanding the associated risks becomes increasingly crucial.



Initiatives for public health education should include specific education on the dangers of hallucinogen use - particularly in cases where there is known predilection to a mental health disorder.



This awareness can be created with targeted community outreach, evidence-based medical guidelines, and collaboration among healthcare providers and mental health specialists.



Another proactive strategy could be mental health checkups for patients before <a href="https://www.earth.com/news/psychedelic-drug-therapy-could-help-treat-alcoholism/" target="_blank" rel="noreferrer noopener">psychedelic therapy</a>. This would allow experts screen for people with a greater risk of an adverse reaction.

Psychedelic use linked to higher risk of schizophrenia

Psychedelic substances, once the mainstay of counterculture, are steadily blending...

The scorching heatwaves we experience, the wildfires that rage across nations, and the invisible carbon dioxide that fills the air are severely impacting our planet.



In 2023, the world saw extreme heatwaves that fueled substantial wildfires and induced severe droughts across the globe. 



What's more, these <a href="https://www.earth.com/news/fast-wildfires-are-gaining-even-more-speed/" target="_blank" rel="noreferrer noopener">adverse conditions</a> significantly weakened the land's ability to absorb atmospheric carbon. 



The result? A notable surge in atmospheric carbon dioxide levels, growing the scale of concern about accelerating climate change.



<h2 class="wp-block-heading" id="h-heat-and-atmospheric-carbon">Heat and atmospheric carbon </h2>



Data from Hawaii's <a href="https://gml.noaa.gov/obop/mlo/aboutus/aboutus.html" target="_blank" rel="noreferrer noopener">Mauna Loa Observatory</a> showed that atmospheric carbon concentrations skyrocketed by an alarming 86% in 2023 compared to 2012. This increase sets a new record high since tracking of these levels began in 1958.



Interestingly, the rise in carbon dioxide levels cannot solely be pointed towards fossil fuel emissions. These, it seems, only rose by roughly 0.6 percent.



So, what's the primary culprit behind the spike in emissions? It's likely due to weakened <a href="https://www.earth.com/news/extreme-fire-risk-has-grown-exponentially-in-a-hotter-climate/" target="_blank" rel="noreferrer noopener">carbon absorption</a> by natural ecosystems.



<h2 class="wp-block-heading" id="h-weakened-carbon-sink">Weakened carbon sink </h2>



An international team of scientists backed by the <a href="https://www.esa.int/Applications/Observing_the_Earth/Extreme_heat_weakens_land_s_power_to_absorb_carbon" target="_blank" rel="noreferrer noopener">ESA</a> Science for Society Near-Realtime Carbon Extremes project - along with the Climate Change Initiative RECCAP-2 project - set out to investigate the root causes of this event.



The experts used global vegetation models and satellite data to expedite a carbon budget report for 2023.



Land typically absorbs about one-third of human-generated carbon dioxide emissions. However, in 2023, this absorption capacity fell to a mere one-fifth of its usual level, marking the weakest performance by land carbon sink in two decades.



<h2 class="wp-block-heading" id="h-extreme-heat-and-carbon-storage-capacity">Extreme heat and carbon storage capacity </h2>



“Our research shows that 30% of this decline was driven by the extreme heat of 2023, which fueled massive <a href="https://www.earth.com/news/ultrafine-particles-in-wildfire-smoke-change-weather-patterns/" target="_blank" rel="noreferrer noopener">wildfires</a> that ravaged vast areas of Canadian forest and triggered severe drought across parts of the Amazon rainforest," said Philippe Ciais, a scientist from France’s Laboratory for Climate and Environmental Sciences.



"These fires and droughts led to substantial vegetation loss, weakening the land ecosystem’s ability to absorb carbon dioxide. This was further compounded by a particularly strong El Niño, which historically reduces the carbon absorption capacity in the Tropics." 



The situation was made worse by a particularly potent El Niño, which historically reduces carbon absorption capacity in the tropics.



<h2 class="wp-block-heading" id="h-carbon-emitted-from-wildfires">Carbon emitted from wildfires</h2>



Widespread wildfires across Canada and droughts in the Amazon in 2023 released nearly the same amount of carbon to the atmosphere as North America's total fossil fuel emissions. 



This finding highlights the severe impact of climate change on natural ecosystems.



The Amazon rainforest, one of the planet's most essential carbon sinks, is showing signs of long-term distress. Some regions of the Amazon that no longer absorb carbon have shifted into net sources of carbon emissions.



<h2 class="wp-block-heading" id="h-earth-s-declining-capacity-to-absorb-carbon">Earth's declining capacity to absorb carbon </h2>



The declining capacity of Earth's land ecosystems to absorb carbon dioxide may signify that these natural carbon sinks are nearing their limits. 



They won't be able to continue to provide the mitigation service of absorbing half of human-induced carbon dioxide emissions.



"Consequently, achieving safe global warming limits will require even more ambitious emission reductions than previously anticipated," Ciais adds.



<h2 class="wp-block-heading" id="h-saving-earth-s-carbon-cycle">Saving Earth's carbon cycle</h2>



The study also highlights that <a href="https://www.earth.com/news/climate-models-underestimate-sea-ice-melt-and-global-warming/" target="_blank" rel="noreferrer noopener">current climate models</a> might be underestimating the pace and impact of extreme events such as droughts and fires on the degradation of these crucial carbon reservoirs.



"Understanding the knock-on effects of climate change on the carbon cycle is imperative, and the two ESA study projects demonstrate the importance of Earth observation in developing methodologies to provide rapid assessment of these impacts globally," said Stephen Plummer, <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">ESA</a> Earth Observation Applications Scientist.



"These results are particularly alarming, especially considering the difficulty the world is having limiting warming to 1.5°C, as laid out in the Paris Agreement," noted Clement Albergel, ESA’s Acting Head of the Actionable Climate Information Section.



Given these alarming revelations, it's vital that we ask ourselves: how can we contribute to mitigating these effects? Can we consume less, recycle more, and seek out greener alternatives in our daily lives? The need for climate action could not be more urgent.



The study is published in the journal <a href="https://academic.oup.com/nsr/advance-article/doi/10.1093/nsr/nwae367/7831648?login=false" target="_blank" rel="noreferrer noopener">National Science Review</a>.

Extreme heat of 2023  weakened Earth's carbon storage capacity

The scorching heatwaves we experience, the wildfires that rage across...

Desolate, arid and virtually lifeless - that's how one would traditionally describe the Atacama Desert. Stretching across the Pacific coast in Chile, this unforgiving territory is known as the driest spot on our planet. It's no surprise that the desert is deemed hostile to most forms of life.



Yet, a closer look at the sandy soil reveals a perfect paradox - a diverse community of resilient microorganisms, thriving in the seeming desolation.



Investigating the function of these microorganisms can be challenging. Modern science tools often hit a wall while trying to separate the genetic material of the living from the dead in this <a href="https://www.earth.com/news/saharan-dust-supports-ocean-life-far-from-the-desert/" target="_blank" rel="noreferrer noopener">microbial community</a>.



But now, a promising solution to this mystery is at hand.



<h2 class="wp-block-heading" id="h-identifying-the-desert-microbes">Identifying the desert microbes </h2>



Presented this week in Applied and Environmental Microbiology, an international team of researchers announces a novel separation technique. 



This innovative method distinguishes extracellular (eDNA) from intracellular (iDNA) genetic material, casting a spotlight on the living members of the elusive microbial community.



The technique is a game-changer in studying microbial life in <a href="https://www.earth.com/news/floods-are-becoming-more-deadly-in-the-desert/" target="_blank" rel="noreferrer noopener">low-biomass environments</a> - an area where conventional DNA extraction methods have been falling short.



The research was led by Dr. Dirk Wagner from the GFZ German Research Centre for Geosciences in Potsdam. He believes this development could usher in a new era in microbial research.



<h2 class="wp-block-heading" id="h-active-life-in-arid-regions-of-desert">Active life in arid regions of desert</h2>



The microbiologists put their novel method to practice on soil samples collected from the Atacama Desert, running along a west-to-east path from the ocean's edge to the foothills of the Andes mountains. 



What they found was intriguing: a variety of potentially active microbes were discovered in the most arid regions of the desert.



"Microbes are the pioneers colonizing this kind of environment and preparing the ground for the next succession of life," said Dr. Wagner. He noted that these processes aren't exclusive to desert lands.



"This could also apply to new terrain that forms after earthquakes or landslides where you have more or less the same situation, a mineral or rock-based substrate."



<h2 class="wp-block-heading" id="h-new-approach-to-dna-extraction">New approach to DNA extraction</h2>



Conventional tools for DNA extraction from <a href="https://www.earth.com/news/desert-grass-survives-by-capturing-moisture-from-fog/" target="_blank" rel="noreferrer noopener">soils</a> often present a blend of living, dormant and dead cells from microorganisms.



“If you extract all the DNA, you have DNA from living organisms and also DNA that can represent organisms that just died or died a long time ago," explained Dr. Wagner.



The formidable challenge, especially in low-biomass environments, is securing sufficient good-quality DNA for metagenomic sequencing to unravel specific microbes and their processes. 



Dr. Wagner and his team have found a way around this by creating a process that filters out intact cells from a mixture, leaving behind eDNA genetic fragments from dead cells.



<h2 class="wp-block-heading" id="h-implications-for-extraterrestrial-life">Implications for extraterrestrial life</h2>



The significance of this research extends far <a href="https://www.earth.com/news/this-desert-moss-might-help-humans-live-on-mars/" target="_blank" rel="noreferrer noopener">beyond Earthly environments</a>. 



The techniques developed for distinguishing living microbial communities in the Atacama Desert could offer a tantalizing approach to astrobiology, a field dedicated to exploring life beyond our planet. 



Mars, with its barren and inhospitable terrain, presents a setting not unlike parts of the Atacama. Here, scientists speculate that if life ever arose, it might have persisted in microbial form beneath the surface. 



By applying this novel genetic separation technique, future missions to Mars could possibly identify signs of life that traditional methods might overlook, thus advancing our understanding of life's potential in the cosmos.



<h2 class="wp-block-heading" id="h-charting-future-research">Charting future research</h2>



The advent of this cutting-edge method represents a paradigm shift in microbial ecology and environmental microbiology. 



It opens up new avenues for research, not only in desolate regions like the Atacama Desert but also in other extreme environments such as Antarctic ice, deep-ocean vents, and arid regions worldwide. 



By accurately categorizing active microorganisms, we can better understand their roles in nutrient cycling, climate change, and biogeochemical processes. 



This refined approach provides a critical tool for scientists aiming to unravel the life forms that have evolved to thrive against the odds. It also lays the groundwork for future discoveries at the intersections of life, earth, and space sciences.



<h2 class="wp-block-heading" id="h-vibrant-life-beneath-atacama-desert">Vibrant life beneath Atacama Desert</h2>



Dr. Wagner plans to extend the study's methodology to other hostile environments. He believes that this technique, which focuses on active microorganisms (iDNA), can provide deeper insights into the active part of the community.



By examining the vibrant life thriving beneath the surface of the Atacama Desert, we are slowly unearthing the secret resilience of microbes in the most <a href="https://www.earth.com/news/oases-grow-by-human-effort-but-face-threats-from-desertification/" target="_blank" rel="noreferrer noopener">arid of environments</a>. 



As we continue to witness the incredible adaptation and survival of life in the harshest of conditions, the lines of possibility for microbial life continue to expand, taking us one step deeper into unraveling the mysteries of life itself.



The study is published in the journal <a href="https://search.app?link=https%3A%2F%2Fjournals.asm.org%2Fdoi%2F10.1128%2Faem.01443-24&amp;utm_campaign=aga&amp;utm_source=agsadl2%2Csh%2Fx%2Fgs%2Fm2%2F4" target="_blank" rel="noreferrer noopener">Applied and Environmental Microbiology</a>.

Living microbes found in the driest desert on Earth

Desolate, arid and virtually lifeless - that's how one would...

Pando, an extraordinary organism residing in Utah, quietly stands out among the myriad of living beings that inhabit our planet, captivating scientists and nature enthusiasts alike. 



This remarkable colony of quaking aspen trees (Populus tremuloides) stretches across 106 acres, and is connected by an extensive underground root system that forms a single, unified organism rather than just a forest of unrelated individuals.



With its remarkable size and age, Pando dwarfs its fellow inhabitants, holding the potential to be not only the oldest living being but also the largest organism on Earth. It is a symbol of nature's resilience and complexity over millennia.



<h2 class="wp-block-heading" id="h-utah-s-pride-the-incredible-pando">Utah's pride: The incredible Pando</h2>



A group of American researchers has suggested that this 106-acre woodland in the heart of Utah could have originated from a single seedling, which sprouted 34,000 years ago, pre-dating the end of the <a href="https://www.earth.com/news/disastrous-climate-changes-of-the-last-ice-age-could-happen-again/" target="_blank" rel="noreferrer noopener">last ice age</a>.



Even bolder estimates propose that this clonal organism, which appears to consist of 47,000 separate trees, might have been present tens of thousands of years earlier.



<h2 class="wp-block-heading" id="h-the-astonishing-life-of-clonal-organisms">The astonishing life of clonal organisms</h2>



Pando (which means "I spread" in Latin) is intriguing because of its massive size, but it also boasts a unique genetic identity shared by all its individual parts that are linked together through one vast network of roots.



This form of asexual reproduction makes Pando a <a href="https://www.earth.com/news/listening-to-the-largest-and-oldest-tree-on-earth-what-does-it-have-to-say/" target="_blank" rel="noreferrer noopener">clonal organism</a>, with each 'tree' being a part of the whole, rooted and growing from the same entity. 



There are other life forms, including fungi and the bristlecone pines on the White Mountains in eastern California, that display similar capabilities. They survive through <a href="https://www.earth.com/news/scientists-have-had-a-breakthrough-in-cloning-coconut-trees/" target="_blank" rel="noreferrer noopener">cloning</a> methods for hundreds, or even thousands of years.



<h2 class="wp-block-heading" id="h-unlocking-pando-s-historical-tales">Unlocking Pando's historical tales</h2>



To discern Pando's true age more accurately, the research team meticulously collected around 500 samples, including root, leaf, and bark, from different parts of this giant organism.



They also obtained specimens from other, unrelated aspens and embarked on a journey to sequence their DNA.



The scientists identified 4,000 genetic variations within these samples, and the mutation patterns narrated a captivating story that dates back potentially between 16,000 and 80,000 years.



<h2 class="wp-block-heading" id="h-unraveling-the-genetic-enigma">Unraveling the genetic enigma</h2>



The researchers, led by Rozenn Pineau of the <a href="https://www.uchicago.edu/en" target="_blank" rel="noreferrer noopener">University of Chicago</a>, noted that they had initially expected a close genetic correlation between trees that are physically near each other.



"You would expect that the trees that are spatially close are also closer genetically," Pineau told Helena Kudiabor at Nature. "But this is not exactly what we find. We found a spatial signal, but that is much weaker than what we expected."



Those trees that were in close proximity did share more similar mutations than those that were far apart - but only slightly more.



This discovery adds a new layer of complexity to understanding Pando's genetic structure and resilience.



Additional research focusing on Pando's mutation history and its genomic protection methods could provide insights into how this plant (and other similar organisms) has managed to survive for millennia.



<h2 class="wp-block-heading" id="h-ensuring-pando-s-enduring-legacy">Ensuring Pando's enduring legacy</h2>



Concerns are mounting over the longevity of Pando. Ensuring its survival will require a deep understanding of this ancient <a href="https://www.earth.com/news/plants-use-dna-duplication-to-increase-their-resilience/" target="_blank" rel="noreferrer noopener">plant's resilience</a> against the assaults of man and nature.



Moreover, similar investigations into other clonal organisms elsewhere may offer Pando competition for its venerable title. 



One competitor lies in a patch of Posidonia oceanica seagrass off the Spanish island of Formentera, which some believe to be more than 200,000 years old.



<h2 class="wp-block-heading" id="h-the-ecological-significance-of-pando">The ecological significance of Pando</h2>



Pando is more than just a marvel of age and size; it plays a crucial role in the local ecosystem. 



This vast network of quaking <a href="https://www.earth.com/news/aspen-forests-could-reverse-biodiversity-loss-in-europe/" target="_blank" rel="noreferrer noopener">aspens</a> supports a diversity of wildlife by providing habitat and food for numerous species, from insects and birds to larger mammals such as deer and elk.



The interconnected root system of Pando also aids in soil stabilization, which prevents erosion and supports the health of the surrounding environment.



However, understanding Pando's ecological contributions has become more urgent than ever, as climate change and human activities threaten its survival. 



Efforts to study and preserve this unique organism are now critical, not only to protect its ancient legacy but also to help maintain the delicate balance of the ecosystem it anchors.



<h2 class="wp-block-heading" id="h-the-enduring-hymns-of-pando">The enduring hymns of Pando</h2>



Pando's survival through the ages is a tribute to time itself. It stands as a constant reminder of the ancient world, sharing with us stories of an era long gone. 



As we continue to unravel the mysteries of Pando, we can only hope that this ancient marvel stands tall and flourishes in the years to come.

The world's largest living organism consists of 47,000 trees

Pando, an extraordinary organism residing in Utah, quietly stands out...

Our world is changing. The ocean is on the rise, threatening to disrupt the lives of coastal communities.



As the water inches its way into people's lives, various agencies and organizations are making strides to prepare for this new reality. Right in the heart of these efforts is NASA, offering critical insights on rising sea levels.



<h2 class="wp-block-heading" id="h-sea-level-data-is-accessible-to-the-public">Sea-level data is accessible to the public</h2>



NASA's extensive global data is now accessible to the public in the brand-new sea level section of the Earth Information Center. 



This comprehensive global sea level <a href="https://www.earth.com/news/global-sea-levels-spiked-dramatically-in-2023/" target="_blank" rel="noreferrer noopener">change</a> website is the product of a collaboration between <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>, the U.S. Department of Defense, the World Bank, the U.S. Department of State, and the UN Development Programme.



The site presents comprehensive projections of expected sea level rise through the year 2150 for coastlines around the globe. It also provides estimates of anticipated flooding for coastal communities or regions over the coming three decades. 



The projections draw on diverse sources such as data gathered by NASA and its collaborators, computer models of ice sheets and the ocean, the latest sea level assessment from the Intergovernmental Panel on Climate Change, and more.



"NASA innovates for the benefit of humanity. Our cutting-edge instruments and data-driven information tools help communities and organizations respond to natural hazards and extreme weather, and inform critical coastal infrastructure planning decisions,” said Karen St. Germain, the director of the Earth Science Division at NASA Headquarters in Washington.



<h2 class="wp-block-heading" id="h-global-sea-level-changes">Global sea level changes</h2>



Major global organizations like the World Bank are set to utilize the valuable data from the global sea level change site for creating Climate Risk Profiles for countries particularly susceptible to sea level <a href="https://www.earth.com/news/pacific-sea-levels-are-rising-faster-than-anywhere-in-the-world/" target="_blank" rel="noreferrer noopener">rise</a>.



The Defense Department will consistently feed sea level rise data into its plans to help predict - and possibly avoid - hazards caused to its facilities by rising oceans.



Similarly, the State Department will use the data for a range of activities, from disaster preparedness to long-term adaptation planning, and supporting partners globally in related efforts.



<h2 class="wp-block-heading" id="h-moment-of-truth-in-our-climate-fight">Moment of truth in our climate fight</h2>



Assistant Secretary-General Selwin Hart, special adviser to the United Nations secretary-general on climate action and just transition, stresses the significance of the current period. 



“We are at a moment of truth in our fight against the <a href="https://www.earth.com/news/2024-shatters-heat-records-earths-hottest-year-is-here/" target="_blank" rel="noreferrer noopener">climate crisis</a>. The science is unequivocal and must serve as the bedrock upon which decision-making is built," said Hart.



"With many communities around the world already facing severe impacts from sea-level rise, this new resource provides a vital tool to help them protect lives and livelihoods."



<h2 class="wp-block-heading" id="h-rising-faster-than-ever">Rising faster than ever</h2>



NASA-led data has revealed that between 1970 and 2023, 96% of countries with coastlines have experienced sea level rise. Furthermore, the rate of this global rise has doubled, from 0.08 inches (0.21 centimeters) per year in 1993 to about 0.18 inches (0.45 centimeters) per year in 2023.



As the rate of sea level rise increases, millions could face the linked effects earlier than anticipated, including larger storm surges, more saltwater intrusion into groundwater, and additional high-tide flood days.



“This new platform shows the timing of future floods and the magnitude of rising waters in all coastal countries worldwide,” said Nadya Vinogradova Shiffer, director of the ocean physics program at NASA Headquarters in Washington.

Earlier data released this year shows that Pacific Island nations will face at least 6 inches (15 centimeters) of sea level rise over the next 30 years. Moreover, the number of high-tide flood days will increase significantly for nearly all Pacific Island nations by the 2050s.



Ben Hamlington is a sea level researcher at NASA’s <a href="https://www.jpl.nasa.gov" target="_blank" rel="noreferrer noopener">Jet Propulsion Laboratory</a> in Southern California and head of the agency’s sea level change science team.



“The data is clear: Sea levels are rising around the world, and they’re rising faster and faster. Having the best information to make decisions about how to plan for rising seas is more crucial than ever,” concluded Hamlington.

Sea level warnings: What coastal cities must prepare for

Our world is changing. The ocean is on the rise,...

The lifeline of our oceans is in danger. A recent study warns us about the impacts of global warming on marine life, with plankton populations at significant risk. 



The study points out a straightforward, yet frequently undervalued reality that if we don't act quickly, vast amounts of marine life could be on the brink of extinction within this century.



<h2 class="wp-block-heading" id="h-plankton-struggle-with-rapid-warming">Plankton struggle with rapid warming</h2>



The research examines the world of <a href="https://www.earth.com/news/plankton-help-predict-ocean-biodiversity-losses/" target="_blank" rel="noreferrer noopener">tiny ocean dwellers</a> known as plankton, which are more important than one might think. 



For the first time, the researchers compared how these tiny creatures responded to significant global warming in the past with how they might react to similar conditions anticipated by the end of our century.



The revelations were rather disturbing. It seems that plankton are struggling to keep up with the current rate of temperature increases. 



<h2 class="wp-block-heading" id="h-plankton-cannot-adapt-quickly-enough">Plankton cannot adapt quickly enough</h2>



Dr Rui Ying, the lead author of the study, led this project during his PhD work in marine ecology at the <a href="https://www.bristol.ac.uk" target="_blank" rel="noreferrer noopener">University of Bristol</a>. 



“The results are alarming as, even with the more conservative climate projections of a 2°C increase, it is clear plankton cannot adjust quickly enough to match the much faster rate of warming which we’re experiencing now and looks set to continue," said Dr. Ying.



“Plankton are the lifeblood of the oceans, supporting the marine food web and <a href="https://www.earth.com/news/tiny-plankton-play-a-big-role-in-the-global-carbon-cycle/" target="_blank" rel="noreferrer noopener">carbon storage</a>. If their existence is endangered, it will present an unprecedented threat that would disrupt the whole marine ecosystem and have devastating, wide-reaching consequences for marine life and also human food supplies.”



<h2 class="wp-block-heading" id="h-predicting-the-future-by-looking-at-the-past">Predicting the future by looking at the past</h2>



To arrive at these conclusions, the scientists developed a new model to analyze how plankton behaved 21,000 years ago, during the last Ice Age.



They compared this with how the plankton might behave under future climate conditions. This approach, which focused on a specific plankton group that has survived through the ages, provides unique insights and an impressive level of accuracy.



“The past is often considered key to understanding what the world could look like in the future. Geological records showed that plankton previously relocated away from the warmer oceans to survive," explained Dr Ying.



“But using the same model of ecology and climate, projections showed the current and future rate of warming was too great for this to be possible again, potentially wiping out the <a href="https://www.earth.com/news/plankton-tiny-ocean-creatures-overlooked-critical-life-on-earth/" target="_blank" rel="noreferrer noopener">precious organisms</a>.”



<h2 class="wp-block-heading" id="h-broader-issue-of-global-warming">Broader issue of global warming</h2>



This research brings attention to the broader issue of global warming and our collective responsibility to curb its effects on plankton and overall marine ecosystems.



The Paris Agreement was a worldwide commitment to keep the increase in global average temperatures well below 2°C (3.6°F) above pre-industrial levels and strive to limit the increase to 1.5°C (2.7°F).



However, a recent United Nations report indicates that the world may face as much as 3.1°C (5.6°F) warming if governments do not act more decisively to reduce carbon emissions.



<h2 class="wp-block-heading" id="h-need-for-global-climate-action">Need for global climate action</h2>



Study co-author Daniela Schmidt is a professor of Earth Sciences at the University of Bristol and a celebrated marine ecologist. She has led multiple Intergovernmental Panel on Climate Change (<a href="https://www.ipcc.ch" target="_blank" rel="noreferrer noopener">IPCC</a>) reports and her insights are critical to understanding the climate crisis.



“This work emphasizes the great risks posed by the dramatically fast <a href="https://www.earth.com/news/oceans-are-quickly-losing-ability-to-support-fish-due-to-plankton-loss/" target="_blank" rel="noreferrer noopener">climate and environmental changes</a> the world is now facing. With these worrying trends set to worsen, there will be very real consequences for our ecosystems and people’s livelihoods, including fishing communities," said Schmidt.



"So, the message is clear - all nations must collectively and individually step up efforts and measures to keep global warming to a minimum.”



With the ocean’s lifeblood under threat, it’s time to act. If tiny plankton are at risk, the entire marine world - and our food supply - could be, too.



The research on plankton tells us that it does not have to be this way - the world can still limit global warming. But in order for that to happen, every nation needs to step up and take action.



The study is published in the journal <a href="https://www.nature.com/articles/s41586-024-08029-0" target="_blank" rel="noreferrer noopener">Nature</a>.

Plankton at risk: Global warming threatens the ocean's lifeline

The lifeline of our oceans is in danger. A recent...

Microplastics and nanoplastics have emerged as pressing global concerns, capturing significant scientific attention and driving advancements in nanotechnology that is aimed at addressing their pervasive presence in the environment.



These minute <a href="https://www.earth.com/news/hundreds-of-thousands-of-nanoplastics-found-in-bottled-water/" target="_blank" rel="noreferrer noopener">particles</a> infiltrate our air, water, and soil, and even make their way into the bodies of animals and humans.



Originating from everyday consumer products and the breakdown of larger plastic materials, they represent an unseen environmental foe with potentially far-reaching impacts on ecosystems and human health.



<h2 class="wp-block-heading" id="h-the-hidden-dangers-of-nanoplastics">The hidden dangers of nanoplastics</h2>



<a href="https://www.earth.com/news/microplastics-pose-a-greater-threat-to-some-ocean-animals/" target="_blank" rel="noreferrer noopener">Microplastics</a>, defined as fragments smaller than 5 mm in diameter, are already recognized as a major issue.



However, nanoplastics, which are nearly a thousand times smaller, pose an even more insidious threat. 



These particles can bypass biological barriers and infiltrate the vital organs of living creatures. Alarmingly, recent research has even detected nanoplastics in the human brain.



Study senior author Henrique Eisi Toma is a professor in the Institute of Chemistry at the University of São Paulo (IQ-USP).



"Nanoparticles aren't visible to the naked eye or detectable using conventional microscopes, so they’re very hard to identify and remove from water treatment systems," said Professor Toma.



<h2 class="wp-block-heading" id="h-nanotechnology-solutions-for-plastic-pollution">Nanotechnology solutions for plastic pollution</h2>



Researchers at USP, with support from FAPESP, have developed a novel solution using nanotechnology.



The team, led by Professor Toma, created a low-cost method employing magnetic nanoparticles functionalized with polydopamine (PDA), a polymer derived from dopamine which is a neurotransmitter present in the human body.



These nanoparticles bind to micro- and nanoplastic waste, allowing for their removal through the application of a magnetic field.



“Polydopamine is a substance that mimics the adhesive properties of mussels, which cling very tenaciously to many surfaces," noted Toma. 



"It adheres firmly to fragments of plastic in water and enables the magnetic nanoparticles to capture them. This undesirable material can then be removed from the water with a magnet."



<h2 class="wp-block-heading" id="h-striving-for-plastic-degradation">Striving for plastic degradation</h2>



The research team aims for more than just the removal of these particles; they are also exploring methods for sustainable degradation. 



By immobilizing lipase, an enzyme capable of breaking down <a href="https://www.earth.com/news/bacteria-can-break-down-pet-pollution-in-ocean-water/" target="_blank" rel="noreferrer noopener">polyethylene terephthalate</a> (PET), the team decomposes PET and other plastics into their basic components, such as terephthalic acid and ethylene glycol, which can be reused in the production of new plastics.



"Our goal isn't just to remove plastic from water but also to contribute to its recycling in a sustainable manner," Toma emphasized.



PET is a significant <a href="https://www.earth.com/news/pollutants-from-fossil-fuels-are-embedded-in-coral-skeletons/" target="_blank" rel="noreferrer noopener">pollutant</a> due to its prevalence in plastic bottles and other common items.



The degradation process developed by Toma's team breaks PET down into monomeric forms, enabling the reuse of these components in new manufacturing processes.



"Our study focused on PET, but other researchers can include other specific enzymes to process different plastics, such as polyamide or nylon, for example," he noted.



<h2 class="wp-block-heading" id="h-challenges-and-complexities">Challenges and complexities</h2>



Addressing the micro- and nanoplastics problem is far from straightforward. 



While <a href="https://www.earth.com/news/yale-scientists-are-turning-wood-into-high-quality-bioplastic/" target="_blank" rel="noreferrer noopener">bioplastics</a> offer a potential solution as they come from renewable sources, they too can fragment into micro- and nanoplastics before fully degrading.



"Being biocompatible, they’re even more insidious because they can interact more directly with our organisms and trigger biological reactions," Toma explained.



An additional concern raised by Professor Toma is the contamination of bottled mineral water. While mineral water is often valued for its taste and mineral content, it can contain higher levels of micro- and nanoplastics than treated tap water.



"Treated potable water undergoes processes such as filtration, coagulation and flotation to eliminate most residues, whereas mineral water, which is better in some ways - it’s lighter, contains more salts and tastes better, for example - isn't processed in any of these ways because that would destroy its properties," said Toma.



"If the environment from which it's collected is contaminated by bioplastics, these particles will reach the consumer."



<h2 class="wp-block-heading" id="h-advancing-solutions-with-nanotechnology">Advancing solutions with nanotechnology</h2>



The scale of this environmental challenge demands continuous innovation and policy intervention. 



The nanotechnology developed by Toma and his colleagues represents a significant advancement, showcasing how science can address complex environmental issues. 



Professor Toma calls for persistent research efforts and urges public administrators to recognize and tackle the problem, stressing the need for collective action to safeguard the planet.



The study is published in the journal <a href="https://linkinghub.elsevier.com/retrieve/pii/S0968432824001392" target="_blank" rel="noreferrer noopener">Micron</a>.

How nanotechnology is fighting microplastic pollution

Microplastics and nanoplastics have emerged as pressing global concerns, capturing...

The era of wondering and wildly speculating may be drawing to a close, with researchers recently devising a new model they're calling the "formula for life." 



The experts hope this tool will calculate the chances of intelligent life existing in our universe and even predict the potential for alien life in future universes.



<h2 class="wp-block-heading" id="h-next-generation-of-intelligent-life">Next generation of intelligent life </h2>



According to this new calculation model, the likelihood of life beyond our galaxy sits at 27 percent, which may let down the 65 percent of American adults who firmly believe in extraterrestrial life.



Interestingly, the chances of <a href="https://www.earth.com/news/are-aliens-sending-radio-signals-to-each-other/" target="_blank" rel="noreferrer noopener">intelligent life</a> existing within our own Milky Way are even lower - just 23 percent.



These estimates come from the concerted efforts of researchers at the <a href="https://search.app?link=https%3A%2F%2Fwww.ed.ac.uk%2F&amp;utm_campaign=aga&amp;utm_source=agsadl2%2Csh%2Fx%2Fgs%2Fm2%2F4" target="_blank" rel="noreferrer noopener">University of Edinburgh</a> and the University of Genevieve. The study suggests that star formation and the evolution of large-scale planets might intertwine to quietly "form the next generation of intelligent life."



<h2 class="wp-block-heading" id="h-dark-energy-and-the-potential-for-alien-life">Dark energy and the potential for alien life</h2>



To understand the potential of other life forms, the team devised a theoretical model that leans heavily on the Drake Equation, developed in 1960. 



This well-known formula calculates the universe's expansion and has been used to research the existence of advanced civilizations in our galaxy.



The researchers emphasized that their calculations do not suggest a number of intelligent life forms but rather estimate the likelihood of their <a href="https://www.earth.com/news/dark-oxygen-in-the-deep-sea-may-hold-clues-about-alien-life/" target="_blank" rel="noreferrer noopener">existence</a>.



Their estimation process takes into account dark energy, which comprises over two-thirds of the universe and fuels its expansion.



"Understanding dark energy and the impact on our universe is one of the biggest challenges in cosmology and fundamental physics," said lead researcher Dr. Daniele Sorini, affiliated with <a href="https://www.durham.ac.uk" target="_blank" rel="noreferrer noopener">Durham University</a>’s Institute for Computational Cosmology.



<h2 class="wp-block-heading" id="h-potential-for-future-alien-life">Potential for future alien life</h2>



In addition to the probabilities of current extraterrestrial life, the researchers' model also accommodates for alien life forms that don't exist yet but could develop in the future. 



To do this, they calculated the amount of ordinary matter that combined to form stars across the universe's history, stretching back a staggering 13.8 billion years.



It seems the chances of <a href="https://www.earth.com/news/cosmic-connection-aliens-could-make-contact-by-2029/" target="_blank" rel="noreferrer noopener">intelligent life</a> appearing in universes beyond our own also hover at around 27 percent. 



"Surprisingly, we found that even a significantly higher dark energy density would still be compatible with life, suggesting we may not live in the most likely of universes," said Dr. Sorini.



<h2 class="wp-block-heading" id="h-implications-for-future-research">Implications for future research</h2>



The pioneering work of modeling the probability of intelligent life in other universes opens up numerous avenues for future research. Scientists are now challenged to refine these models further, grounding them in observations and experiments to reach more precise conclusions. 



Such work may involve advancing our understanding of dark matter and energy - components of the universe that remain elusive yet crucial to grasping the cosmic puzzle.



This pursuit could bridge the gap between theoretical physics and cosmology, bringing them closer within the realms of empirical science.



<h2 class="wp-block-heading" id="h-interplay-of-gravity-and-alien-life">Interplay of gravity and alien life</h2>



Another intriguing factor in cosmic life creation is gravity's role. Gravity influences the formation of stars and galaxies, effectively setting the stage for potential habitats where life could develop. 



The extent of gravity's influence in these processes highlights its importance, not just in structural formation, but in setting conditions that could favor the emergence of life. 



Existing research suggests that regions with optimal gravity balance might support complex planetary systems, paving the way for biological evolution. 



As scientists continue to explore the mysteries of the universe, understanding the precise role of gravity will add another layer to our comprehension of life's cosmic potential.



<h2 class="wp-block-heading" id="h-from-speculation-to-exploration">From speculation to exploration</h2>



"It will be exciting to employ the model to explore the emergence of life across different universes and see whether some fundamental questions we ask ourselves about our own universe must be reinterpreted," noted study co-author Lucas Lombriser, a professor at the University of Genevieve.



If this research can help us to better understand our own universe and its likelihood for hosting life, it seems we have come a long way from wild speculation to measured investigation into our place in the cosmos.



So, what does this all mean for us? Are we on the brink of making contact with alien life forms? While the research findings might lead some to temper their expectations, the search for extraterrestrial life continues.



In the end, we need to remember that the universe is vast, mind-bogglingly diverse, and still largely unexplored. The <a href="https://www.earth.com/news/finding-alien-life-searching-for-color-purple-not-green/" target="_blank" rel="noreferrer noopener">potentials for life</a> - both as we know it and beyond our current comprehension - remain a thrilling frontier in scientific exploration.



The study is published in the journal <a href="https://academic.oup.com/mnras/article/535/2/1449/7896079?login=false#493432585" target="_blank" rel="noreferrer noopener">Monthly Notices of the Royal Astronomical Society</a>.

What are the chances that alien life exists?

The era of wondering and wildly speculating may be drawing...

Roughly 233 million years ago, Earth's continents were fused into one massive landmass, and life as we know it was on the brink of transformation due to a one-million-year period of rain called the Carnian Pluvial Episode (CPE).



An international team of scientists has found evidence of this significant extinction event, which appears to have paved the way for dinosaurs to become the dominant creatures on Earth.



Involved in this important research are Dr. Jacopo Dal Corso from the <a href="https://en.cug.edu.cn/" target="_blank" rel="noreferrer noopener">China University of Geosciences</a> at Wuhan and Professor Mike Benton from the <a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>. 



Their collaborative efforts have pieced together a pivotal moment in our planet's history that reshaped life both on land and in the oceans.



<h2 class="wp-block-heading" id="h-carnian-pluvial-episode">Carnian Pluvial Episode</h2>



Back in the <a href="https://www.earth.com/news/early-dinosaurs-benefited-from-changes-in-global-climate/" target="_blank" rel="noreferrer noopener">Late Triassic period</a>, all the continents were joined together in a supercontinent known as Pangea, surrounded by the vast Panthalassa Ocean. The interior of <a href="https://www.earth.com/earthpedia-articles/supercontinents-101-pannotia-gondwana-and-pangea/" target="_blank" rel="noreferrer noopener">Pangea</a> was mostly dry and arid, with rainfall occurring mainly near the coastal regions. 



This dry spell took a dramatic turn when a layer of dark gray rock was discovered in Austria's Northern Limestone Alps in the 1970s by geologists Schlager and Schollnberger. 



This layer indicated wet conditions sandwiched between arid periods, suggesting a global climate event -- the Carnian Pluvial Episode.



So, what caused this sudden shift to a wetter climate? The main culprit appears to be massive volcanic eruptions in the Wrangellia Province, an area that now includes parts of Alaska and British Columbia. 



These eruptions released enormous amounts of <a href="https://www.earth.com/news/jurassic-rocks-reveal-new-details-about-earths-climate-system/" target="_blank" rel="noreferrer noopener">carbon dioxide</a> into the atmosphere. 



"The eruptions peaked in the Carnian," notes Dr. Jacopo Dal Corso. "They were so huge, they pumped vast amounts of greenhouse gases like carbon dioxide, leading to spikes of global warming."



<h2 class="wp-block-heading" id="h-pangea-biodiversity-and-evolution">Pangea, biodiversity, and evolution</h2>



The supercontinent known as Pangea joined together almost all of Earth's landmasses into one massive landmass. 



Imagine all the continents we know today -- North America, South America, Africa, Europe, Asia, Australia, and Antarctica -- snapped together like pieces of a giant puzzle. 



Pangea formed around 335 million years ago during the late Paleozoic era and dominated the planet until it began to break apart about 175 million years ago. 



This massive gathering of land had a huge impact on the climate, sea levels, and the distribution of plants and animals across the globe.



As Pangea started to split apart, it set the stage for the continents to drift to their current positions through the process of plate tectonics. 



This breakup led to the formation of the Atlantic Ocean and reshaped ecosystems, creating new environments for species to evolve and adapt. 



<h2 class="wp-block-heading" id="h-mass-extinction-and-new-beginnings">Mass extinction and new beginnings</h2>



The surge in <a href="https://www.earth.com/news/report-earth-is-headed-for-an-irreversible-climate-disaster/" target="_blank" rel="noreferrer noopener">greenhouse gases</a> caused global temperatures to rise by about 5 to 7 degrees Fahrenheit, amplifying evaporation from the seas and triggering increased rainfall worldwide. 



This climate chaos led to significant biodiversity loss. Many species couldn't adapt to the rapid environmental changes, resulting in a mass extinction event. But nature abhors a vacuum. 



As some species disappeared, new ones emerged to fill the gaps, leading to ecosystems that began to resemble those we see today.



"The new floras probably provided slim pickings for the surviving <a href="https://www.earth.com/news/animals-with-high-body-temperatures-often-become-herbivores/" target="_blank" rel="noreferrer noopener">herbivorous reptiles</a>," says Professor Mike Benton. 



"We now know that <a href="https://www.earth.com/news/rare-triassic-fossil-gondwanax-paraisensis-may-rewrite-history-of-dinosaurs/" target="_blank" rel="noreferrer noopener">dinosaurs originated</a> some 20 million years before this event, but they remained quite rare and unimportant until the Carnian Pluvial Episode hit. It was the sudden arid conditions after the humid episode that gave dinosaurs their chance."



<h2 class="wp-block-heading" id="h-dinosaurs-emerge-from-the-carnian-pluvial">Dinosaurs emerge from the Carnian Pluvial</h2>



As the climate shifted back to drier conditions, dinosaurs seized the opportunity to thrive. This period also saw the rise of the first turtles, crocodiles, lizards, and even the <a href="https://www.earth.com/news/incredible-discovery-some-mammals-attacked-dinosaurs-and-they-often-won-the-battle/" target="_blank" rel="noreferrer noopener">earliest mammals</a>. 



The expansion of conifer forests created new habitats, and these emerging animal groups diversified life on land in remarkable ways.



The oceans weren't spared from the upheaval. The Carnian Pluvial Episode marks the beginning of <a href="https://www.earth.com/news/can-we-save-coral-reefs-with-selective-breeding/" target="_blank" rel="noreferrer noopener">modern coral reefs</a> and the appearance of many groups of plankton. 



These changes indicate significant shifts in ocean chemistry and the carbonate cycle, affecting the entire marine food chain and leading to new forms of marine life.



<h2 class="wp-block-heading" id="h-recognizing-a-sixth-mass-extinction">Recognizing a sixth mass extinction</h2>



Until now, scientists had identified five <a href="https://www.earth.com/news/what-was-the-cause-of-earths-largest-mass-extinction/" target="_blank" rel="noreferrer noopener">major mass extinctions</a> over the past half-billion years. These events dramatically reshaped life's trajectory on Earth. 



"So far, paleontologists had identified five 'big' mass extinctions in the past 500 million years of the history of life," says Dr. Dal Corso. 



"We have identified another great extinction event, and it evidently had a major role in helping to reset life on land and in the oceans, marking the origins of modern ecosystems."



<h2 class="wp-block-heading" id="h-lessons-from-this-carnian-pluvial">Lessons from this Carnian Pluvial</h2>



The Carnian Pluvial Episode offers valuable insights into how massive volcanic eruptions and the resulting climate shifts can have far-reaching consequences. 



The release of greenhouse gases like carbon dioxide led to global warming, increased rainfall, and environmental upheaval. 



In our current era, human activities are raising <a href="https://www.earth.com/news/2023-climate-change-report-record-high-temperatures-greenhouse-gases-sea-level-rise/" target="_blank" rel="noreferrer noopener">greenhouse gas levels</a>, leading to climate change. Studying events like the CPE can help us understand how ecosystems respond to rapid environmental changes.



<h2 class="wp-block-heading" id="h-massive-volcanic-events">Massive volcanic events</h2>



Dr. Dal Corso emphasizes the scale of these ancient volcanic events, saying, "The eruptions were so huge, they pumped vast amounts of greenhouse gases like carbon dioxide, and there were spikes of global warming." 



His observations highlight how natural events can dramatically alter our planet's climate.



"I had noted a floral switch and ecological catastrophe among the herbivores back in 1983 when I completed my PhD," Professor Benton notes.



His decades of work illustrate how scientific understanding evolves, building on clues from various fields to piece together Earth's complex history.



Learning about events from millions of years ago requires collaboration across multiple scientific disciplines, including geology, paleontology, and climate science. 



Discoveries like the Carnian Pluvial Episode showcase the importance of interdisciplinary research in deepening our understanding of Earth's past.



<h2 class="wp-block-heading" id="h-why-does-any-of-this-matter">Why does any of this matter?</h2>



As we face our own environmental challenges today, looking back at events like the Carnian Pluvial Episode can inform our actions. 



If natural volcanic activity could cause such drastic changes, it raises questions about the impact of human-induced climate change. 



How might life on Earth adapt -- or struggle to adapt -- in the face of current environmental shifts?



The story of the Carnian Pluvial Episode demonstrates Earth's resilience and ability to recover and evolve after catastrophic events. 



A period of massive volcanic eruptions and climate upheaval set the stage for the rise of dinosaurs and the formation of ecosystems that continue to influence life today. 



As we continue to explore our planet's history, each discovery offers a new perspective on the resilience and adaptability of life on Earth.

One million years of heavy rain triggered Earth's era of dinosaur dominance

Roughly 233 million years ago, Earth's continents were fused into...

In a quiet and picturesque corner of southern Brazil known as Paraíso do Sul, an extraordinary treasure was uncovered -- a fossil so ancient and well-preserved that it may potentially rewrite the narrative of dinosaur evolution.



This remarkable fossil belonged to a dog-sized reptile named Gondwanax paraisensis that roamed the region approximately 237 million years ago. 



This was during the Triassic period -- a time when Earth’s ecosystems were teeming with evolutionary experiments.



As a newly identified species, this fossil holds tremendous potential as a key to unraveling the mysteries surrounding the origin and early development of the oldest dinosaurs.



Although this fascinating discovery has sparked significant intrigue and excitement among paleontologists, the exact position of the fossil in the complex evolutionary tree of life still remains a subject of debate and careful scientific scrutiny.



<h2 class="wp-block-heading" id="h-dinosaur-history-written-in-stone">Dinosaur history written in stone</h2>



In the realms of science, every fossil discovery is like a puzzle piece that can help us better understand our past. And when it comes to the world of paleontology, there are still many puzzles waiting to be solved.



Gondwanax paraisensis walked on four legs and <a href="https://en.wikipedia.org/wiki/Gondwanax#/media/File:Gondwanax_paraisensis.png" target="_blank" rel="noreferrer noopener">was 39 inches in length</a>, with a long tail. It belonged to an extinct group of <a href="https://www.earth.com/news/past-climate-change-drove-the-rapid-evolution-of-reptiles/" target="_blank" rel="noreferrer noopener">reptiles</a> known as silesaurids. These were not true dinosaurs, but are considered a closely related sister group to the dinosaurs.



However, this newly discovered fossil is one of the oldest silesaurids found anywhere in the world, and it may lead scientists to challenge currently accepted theories about the lineage and early <a href="https://www.earth.com/news/dinosaurs-may-have-become-warm-blooded-180-million-years-ago/" target="_blank" rel="noreferrer noopener">evolution of dinosaurs</a>.



"The most important part of this finding is its age,” said Rodrigo Temp Müller, the sole author of the study and a paleontologist at <a href="https://www.ufsm.br/orgaos-de-apoio/sai/welcome-to-ufsm" target="_blank" rel="noreferrer noopener">Federal University of Santa Maria</a> in Brazil. “Because it's so old, it gives us clues as to how dinosaurs came to be."



<h2 class="wp-block-heading" id="h-currently-accepted-dinosaur-evolution-theory">Currently accepted dinosaur evolution theory</h2>



Scientists think dinosaurs first appeared about 230 million years ago during the Triassic period. They evolved from earlier reptiles and quickly diversified into a bunch of different species. 



Over time, dinosaurs became the dominant land animals, filling all sorts of ecological roles. Some grew to massive sizes like the <a href="https://www.earth.com/news/qunkasaura-pintiquiniestra-new-sauropod-dinosaur-discovered-in-spain/" target="_blank" rel="noreferrer noopener">sauropods</a>, while others became fierce predators like the <a href="https://www.earth.com/news/t-rex-was-about-70-percent-bigger-than-we-thought/" target="_blank" rel="noreferrer noopener">Tyrannosaurus rex</a>. 



It's wild to consider how they adapted and evolved unique features like horns, armor, and even feathers over millions of years.



One of the coolest things we've learned is that not all dinosaurs went extinct -- birds are actually their modern descendants. 



Birds evolved from small, <a href="https://www.earth.com/news/dinosaurs-evolved-feathers-for-much-more-than-just-flying/" target="_blank" rel="noreferrer noopener">feathered theropods</a>, meaning every time you see a pigeon or a hawk, you're looking at a living dinosaur. 



This evolutionary link is supported by numerous fossil discoveries that show similarities in skeletal structures, feather patterns, and nesting behaviors. 



Additionally, ongoing research continues to uncover how dinosaurs interacted with their environments and each other, shedding light on their complex social behaviors and survival strategies.



<h2 class="wp-block-heading" id="h-a-lineage-of-questions">A lineage of questions</h2>



There is an ongoing debate among paleontologists about where silesaurids fit in terms of dinosaur evolution. Were they actual dinosaurs or were they just closely related ancestors?



The answer to this question is not straightforward. Some scientists believe that silesaurids are a sister group to dinosaurs, implying that they share a common ancestor but evolved separately.

Credit: Gondwana research</figcaption></figure>



Others, however, hypothesize that some silesaurids may have evolved into ornithischians -- <a href="https://www.earth.com/news/isle-of-wight-fossils-suggest-that-europe-had-unique-plant-eating-dinosaurs/" target="_blank" rel="noreferrer noopener">herbivorous dinosaurs</a>, such as the <a href="https://www.earth.com/news/armor-was-a-boomerang-trait-in-the-story-of-dinosaur-evolution/" target="_blank" rel="noreferrer noopener">Stegosaurus</a> and <a href="https://www.earth.com/news/triceratops-dinosaurs-seem-to-have-developed-complex-social-structures/" target="_blank" rel="noreferrer noopener">Triceratops</a>, that possessed a bird-like pelvic structure.



Understanding silesaurids could potentially lead to a better understanding of what physical traits contributed to the success of early dinosaurs.



However, solving this puzzle has not been an easy task as many fossils of silesaurids are found incomplete or fragmented, making it difficult for scientists to reach consensus regarding the position of silesaurids in the evolutionary tree of dinosaurs. 



<h2 class="wp-block-heading" id="h-new-clues-about-the-history-of-dinosaurs">New clues about the history of dinosaurs </h2>



Physician Pedro Lucas Porcela Aurélio, who discovered the new fossil in 2014, was hit by an indescribable feeling. "Being the first human to touch something from 237 million years ago is extraordinary," he remarked.



When Aurélio handed over the fossil to the paleontologists in 2021, it was encased in hard rock with only the vertebrae visible. 



Surprisingly, Gondwanax was found to have three vertebrae in its hips, unlike its relatives who only had two. This difference suggested that this reptile may have been more dinosaur-like than previously assumed.



If this hypothesis is confirmed, it would not only extend the history of <a href="https://www.earth.com/news/how-did-bird-hipped-dinosaurs-evolve/" target="_blank" rel="noreferrer noopener">ornithischians</a> (bird-like dinosaurs) by up to ten million years, but it would also significantly alter our understanding of dinosaur origin.



<h2 class="wp-block-heading" id="h-what-happens-next">What happens next?</h2>



Despite the enthusiasm around the discovery, scientists still need more fossil evidence to confirm this theory. 



Steve Brusatte, a paleontologist from the <a href="https://www.ed.ac.uk/" target="_blank" rel="noreferrer noopener">University of Edinburgh</a>, highlighted this need for further exploration. 



"I wish I could say that this new silesaurid fossil solves the riddle once and for all," he said. "But for me, it is still an open question."



We will be waiting eagerly for more pieces of this ancient puzzle to surface. Until then, the mystery of the dog-sized reptile continues to linger.

Rare Triassic fossil discovery may rewrite the history of dinosaurs

In a quiet and picturesque corner of southern Brazil known...

Predicting extreme weather is one of the challenges that has consistently daunted meteorologists and scientists all over the world. 



Weather events, especially in a time of increasing climate volatility, can be unpredictable and have far-reaching impacts. However, the weather forecasting puzzle may have a new piece, thanks to a recent study on electric fields.



<h2 class="wp-block-heading" id="h-electric-field-during-severe-weather">Electric field during severe weather</h2>



The study, led by Dr. Assaf Hochman from The Hebrew University and Professor Yoav Yair from Reichmann University, examined how atmospheric electric field measurements can help predict severe weather events.



Scientists closely examined "Cyprus Lows," which are low-pressure winter <a href="https://www.earth.com/news/2024-shatters-heat-records-earths-hottest-year-is-here/" target="_blank" rel="noreferrer noopener">weather systems</a> in southern Israel's arid Negev Desert. 



The goal was to understand how the electric field plays a role in anticipating heavy precipitation.



<h2 class="wp-block-heading" id="h-how-do-electric-fields-relate-to-weather">How do electric fields relate to weather?</h2>



During weather events known as "wet" Cyprus Lows - when rain falls as a cold front passes - the researchers observed considerable increases in the potential gradient of the electric field.



They found that the typical fair-weather levels (100–200 volts per meter) could skyrocket to hundreds or even thousands of volts per meter during rainfall.



<h2 class="wp-block-heading" id="h-are-all-clouds-created-equal">Are all clouds created equal?</h2>



Interestingly, these electric surges occurred as convective clouds passed overhead, suggesting that different cloud types produce unique electric field patterns. 



And, surprisingly, <a href="https://www.earth.com/news/scorching-summer-of-2024-could-make-it-the-hottest-year-on-record/" target="_blank" rel="noreferrer noopener">factors</a> other than rain intensity, such as the structure of a cloud and the electrical charge of rain droplets, played influential roles.



<h2 class="wp-block-heading" id="h-predicting-weather-saving-lives">Predicting weather, saving lives</h2>



The ability to correlate electric field variations with specific weather conditions could be a significant step towards improving nowcasting systems for <a href="https://www.earth.com/news/distress-signals-earths-water-cycle-is-becoming-more-erratic/" target="_blank" rel="noreferrer noopener">predicting extreme weather</a>. 



This advancement is especially crucial for regions prone to flash floods and sudden weather changes.



<h2 class="wp-block-heading" id="h-weather-and-electric-field-variations">Weather and electric field variations</h2>



In a country like Israel, where desert and Mediterranean climates collide, slight shifts in a low-pressure system's location can cause dramatic local weather changes. 



Thus, maintaining a watchful eye on electric field dynamics could be an early warning system for severe weather, enhancing community preparedness in our rapidly changing climate.



"This research demonstrates how electric field variations can serve as indicators of shifting weather patterns, allowing us to anticipate severe weather events in real-time," explained Dr. Yaniv. 



"The ability to identify these changes early is especially important in vulnerable regions like Israel, where even minor shifts in climate conditions can lead to significant local impacts."



<h2 class="wp-block-heading" id="h-technology-in-weather-forecasting">Technology in weather forecasting</h2>



Recent advancements in technology have had profound effects on the field of meteorology, offering promising tools to further understand and predict <a href="https://www.earth.com/news/snowflake-patterns-can-help-predict-rainfall/" target="_blank" rel="noreferrer noopener">weather phenomena</a>. 



The integration of satellite imagery, high-performance computing, and machine learning algorithms provides meteorologists with unprecedented data precision. 



These technologies enable the development of dynamic weather models that can simulate complex atmospheric processes with greater accuracy. 



By incorporating the latest data from atmospheric electric fields, alongside traditional meteorological inputs, forecasting models can offer more timely and reliable predictions, potentially saving lives and safeguarding property in hazard-prone areas.



<h2 class="wp-block-heading" id="h-future-directions-and-implications">Future directions and implications</h2>



The implications of the research from <a href="https://en.huji.ac.il" target="_blank" rel="noreferrer noopener">Hebrew</a> and <a href="https://www.runi.ac.il/en/" target="_blank" rel="noreferrer noopener">Reichmann</a> Universities extend beyond the borders of Israel, offering a blueprint for tackling similar issues worldwide. 



As climate change continues to challenge the predictability of weather systems globally, understanding electric field variations could offer a universal tool for improving nowcasting capabilities. 



Future research could focus on integrating this approach into global weather prediction systems, enabling countries with diverse climates to enhance their adaptive strategies. 



Furthermore, collaboration between meteorologists, engineers, and policy-makers will be crucial in operationalizing these findings, ensuring that the benefits are disseminated at local, regional, and global scales. 



Ultimately, as research continues to evolve, it provides hope for more effective responses to the complex challenges posed by our changing climate.



<h2 class="wp-block-heading" id="h-electric-fields-and-weather-monitoring">Electric fields and weather monitoring</h2>



The study highlights the importance of incorporating electric field observations into weather monitoring systems.



The implications are particularly relevant for arid and semi-arid regions increasingly exposed to <a href="https://www.earth.com/news/cities-experience-more-rainfall-than-surrounding-areas/" target="_blank" rel="noreferrer noopener">climate change impacts</a>. 



The ability to anticipate and predict severe weather events can make the difference between life and death, especially in regions highly susceptible to weather changes.



<h2 class="wp-block-heading" id="h-new-dawn-in-weather-predictions">New dawn in weather predictions</h2>



While scientists and meteorologists will need to further investigate how electric field variations could be efficiently integrated into weather prediction systems, this study provides important insights.



It presents a new perspective, shining a light on the countless benefits of looking skywards and understanding the electric dynamics at play in our atmosphere.



The study is published in the journal <a href="https://www.sciencedirect.com/science/article/pii/S0169809524005398?via%3Dihub" target="_blank" rel="noreferrer noopener">Atmospheric Research</a>.

Electric field signals can help us predict extreme weather

Predicting extreme weather is one of the challenges that has...

Our bodies need movement, starting from a young age. A recent study confirms this, linking prolonged sitting with a spike in blood pressure.



The study suggests that for every six hours of sedentary behavior per day from childhood through young adulthood, a 4 mmHg increase in systolic blood pressure may occur. Simply put, prolonged sitting and inactivity can raise your blood pressure from childhood all the way into your early adult years.



<h2 class="wp-block-heading" id="h-sitting-time-and-blood-pressure">Sitting time and blood pressure</h2>



The study, conducted by the Universities of <a href="https://www.bristol.ac.uk" target="_blank" rel="noreferrer noopener">Bristol</a> and <a href="https://www.exeter.ac.uk" target="_blank" rel="noreferrer noopener">Exeter</a> in the UK and the University of Eastern Finland, tracked the activities and <a href="https://www.earth.com/news/sitting-too-much-can-cause-premature-aging-even-if-you-exercise/" target="_blank" rel="noreferrer noopener">health outcomes</a> of 2,513 children from ages 11 to 24 years. 



The children’s activities were broken down into sedentary periods, periods of light physical activity (LPA), and intervals of moderate-to-vigorous physical activity (MVPA).



As the children grew older, an increase in sedentary time and a decrease in LPA were recorded. When comparing the changes in the subjects' blood pressure rates from childhood to adulthood, a persistent rise in sedentary time was linked with an average 4 mmHg excess spike in systolic blood pressure. 



Interestingly, while moderate-to-vigorous physical activity did not lower blood pressure, participation in light physical activity from childhood reduced the final level by 3 mmHg.



<h2 class="wp-block-heading" id="h-less-sitting-time-for-healthy-blood-pressure">Less sitting time for healthy blood pressure</h2>



Andrew Agbaje, a physician and associate professor of Clinical Epidemiology and Child Health at the <a href="https://www.uef.fi/en" target="_blank" rel="noreferrer noopener">University of Eastern Finland</a>, highlights the significance of these findings.



“When 10 minutes out of every hour spent sedentary was replaced with an&nbsp;equal amount of LPA from childhood through young adulthood in a simulation model, systolic blood pressure decreased by 3 mmHg and diastolic blood pressure by 2 mmHg," said Agbaje.



"This is significant, as it has been reported in adults that a systolic blood pressure reduction of 5 mmHg decreases the risk of heart attack and stroke by ten percent.”



<h2 class="wp-block-heading" id="h-world-s-longest-follow-up">World's longest follow-up</h2>



This study is the world's largest and longest follow-up of accelerometer-measured movement behavior and blood pressure progression in youth. 



The research not only took into account blood pressure, sitting time, LPA, and MVPA, but it also included repeated measures of fasting blood samples at ages 11, 15, and 24 years. 



Additionally, socio-economic status, family history of cardiovascular disease, and smoking status were accounted for in the analyses.



A striking revelation in the study was that previous attempts to lower blood pressure in young individuals through MVPA-based randomized controlled trials were unsuccessful. An increase in muscle mass due to MVPA, it seems, merely enhances a physical increase in blood pressure. 



This finding shows how crucial it is to focus on <a href="https://www.earth.com/news/walking-can-counteract-the-health-risks-of-sitting/" target="_blank" rel="noreferrer noopener">light physical activities</a>, rather than high-intensity workouts, in controlling blood pressure in young individuals.



<h2 class="wp-block-heading" id="h-key-to-healthy-blood-pressure">Key to healthy blood pressure</h2>



The World Health Organization estimates that physical inactivity-related diseases could cause 500 million new cases by 2030. Half of these cases might be linked to high blood pressure, highlighting the urgent need for proactive measures to reduce sitting time.



"At least three hours of LPA per day is critical to preventing and <a href="https://www.earth.com/news/just-5-minutes-of-daily-exercise-can-lower-blood-pressure/" target="_blank" rel="noreferrer noopener">reversing elevated blood pressure</a> and hypertension. Examples of LPA are long walks, house chores, swimming, and bicycling," said Dr. Agbaje.



"We all, parents, paediatricians and policymakers included, should encourage children and adolescents to participate in LPA to keep their blood pressure in a healthy range."



<h2 class="wp-block-heading" id="h-technology-and-light-physical-activity">Technology and light physical activity </h2>



Technology offers both challenges and opportunities for getting kids active. While screens can lead to less outdoor play, we can use tech to promote movement and reduce sitting time. 



Wearable fitness trackers and apps help kids stay active by tracking their steps, reminding them to move, and providing fun challenges. 



Schools and communities can make a difference by using these tools to inspire kids to engage in activities through games and rewards.



<h2 class="wp-block-heading" id="h-supporting-the-research">Supporting the research</h2>



Dr. Agbaje's research group, urFIT-child, is backed by grants from multiple esteemed foundations, including the Jenny and Antti Wihuri Foundation, the Finnish Cultural Foundation Central Fund, and the Novo Nordisk Foundation, among others.



Their work continues to shed light on the importance of reducing sitting and promoting light physical activity to maintain healthy blood pressure in our growing generation.



Remember – sit less, move more. Your blood pressure, your <a href="https://www.earth.com/news/sedentary-time-in-childhood-linked-to-heart-enlargement/" target="_blank" rel="noreferrer noopener">heart</a>, and ultimately, your health, will thank you for it.



The study is published in the <a href="https://onlinelibrary.wiley.com/doi/10.1002/jcsm.13639" target="_blank" rel="noreferrer noopener">Journal of Cachexia Sarcopenia and Muscle</a>.
