Do you recall those childhood days when you eagerly anticipated bedtime stories about Peter Rabbit, Toad or Ratty from The Wind in the Willows? Or the excitement that washed over you every time you opened a children's book teeming with playful, animated animals? 



Well, a new study is giving us a fresh perspective on the role of these furry, iconic characters.



<h2 class="wp-block-heading" id="h-children-s-books-animal-characters">Children's books animal characters</h2>



The research has shed light on the <a href="https://www.earth.com/news/toddlers-learn-faster-after-witnessing-impossible-events/" target="_blank" rel="noreferrer noopener">potential influence</a> of non-human characters in children's books.



The researchers aimed to gauge how these animal characters affected children's theory of mind skills - crucial abilities which include deciphering social changes in the environment based on voice tone, word choice, or facial expressions.



They worked with over 100 children aged five to 10, each of whom were tested on their theory of mind skills after hearing stories featuring animal characters, as well as those highlighting human characters.



<h2 class="wp-block-heading" id="h-human-vs-animal-characters-in-books">Human vs. animal characters in books</h2>



The study unveiled an interesting pattern. When exposed to stories centered around human characters, an age-related progression was observed. 



Older children were consistently outperforming their younger counterparts, with 3rd grade children surpassing the researchers' expectations in tests featuring human characters.



But the revelations didn't stop there. The tests that involved animal characters threw up another surprise. 



The younger participants were able to match the scores achieved by pupils in 3rd grade, who were two years their senior. That's quite a feat for our young champions.



<h2 class="wp-block-heading" id="h-new-insight-into-children-s-development">New insight into children's development</h2>



These findings, published in the Journal of Experimental Child Psychology, highlight the importance of both human and non-human characters in <a href="https://www.earth.com/news/outdoor-classes-improve-childrens-mental-health/" target="_blank" rel="noreferrer noopener">children's developmental stages</a>.



The research was led by Dr. Gray Atherton and Dr. Liam Cross from the University of Plymouth’s <a href="https://www.plymouth.ac.uk/schools/psychology" target="_blank" rel="noreferrer noopener">School of Psychology</a>.



"Animals play a huge part of children’s stories, whether that is in books and comics or through TV and film. We wanted to test if that is down to more than simply liking the characters, and whether there are actual benefits of children learning through by watching or reading about animals and if this changes over time," said Dr. Atherton.



"Our findings showed that both human and non-human characters are important in helping children interpret the world around them, and that they play differing roles at different stages in their development. Adapting activities and lessons in nurseries and the early school years to take that into account could be hugely effective in helping to support their development."



<h2 class="wp-block-heading" id="h-implications-for-educators-and-parents">Implications for educators and parents</h2>



The insights gained from this study have substantial implications for educators and parents aiming to support children's cognitive and social development.



By incorporating both human and animal characters into books, educators can craft a more balanced learning environment that caters to the diverse needs of children across age groups. 



Parents, too, can enrich their children's home learning experiences by selecting a variety of stories that include both human and animal protagonists. 



This approach not only makes reading sessions more engaging but also aids in developing empathy and understanding of complex social scenarios.



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



While this study provides valuable insights, it also opens avenues for further exploration. 



Future research could go deeper into the types of animal characteristics that are most effective in nurturing children's theory of mind. For instance, exploring whether anthropomorphized animals or more realistic portrayals have differing <a href="https://www.earth.com/news/parents-who-use-humor-have-better-relationships-with-their-children/" target="_blank" rel="noreferrer noopener">impacts</a>. 



Similarly, cross-cultural studies could investigate whether the affinity towards animal characters holds true in diverse cultural contexts. These inquiries could refine understanding and application in educational strategies, enhancing the efficacy of storytelling as a developmental tool.



<h2 class="wp-block-heading" id="h-animal-characters-and-autism-treatment">Animal characters and autism treatment</h2>



In previous studies, Dr. Atherton and Dr. Cross examined the factors influencing the educational and social development of individuals with autism and learning difficulties.



The experts launched initiatives proving how board and online games can bolster confidence among people with autism. 



Borrowing insights from this research, the scholars now plan to dig deeper to explore if their findings could provide specific benefits to children with such conditions.



Dr. Cross envisions a significant impact of this study on individuals with autism or <a href="https://www.earth.com/news/kids-with-behavioral-issues-have-high-cortisol-levels-in-their-hair/" target="_blank" rel="noreferrer noopener">other conditions</a> affecting their learning. 



<h2 class="wp-block-heading" id="h-a-new-way-of-looking-at-animal-characters">A new way of looking at animal characters</h2>



The researchers have observed how tasks involving animal characters can result in autistic individuals performing on par with non-autistic children. 



The plan is to replicate this study with autistic children in an effort to unveil more effective ways to support them at a critical stage in their development.



In a nutshell, this study has unraveled an entirely new dimension of how we view animals in children's books. 



Those delightful animal characters do more than simply entertain; they help shape our children's minds and understanding of the world around them in their formative years.

Scientists study the effect of smoke particles on Earth's climate. A scientist at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science is leading an upcoming international research campaign to study a significant contributor to regional climate warming - smoke. The first-of-its-kind research experiment begins on June 1, 2016 from Ascension Island in the southeastern Atlantic Ocean. The experiment, called LASIC (Layered Atlantic Smoke Interactions with Clouds), is part of a broader international scientific collaboration led by the Atmospheric Radiation Measurement (ARM) Climate Research Facility deployment. The broad collaboration is detailed in a new article in the July <a href="http://journals.ametsoc.org/doi/pdf/10.1175/BAMS-D-15-00082.1" target="_blank" rel="noopener noreferrer">Bulletin of the American Meteorological Society</a>.

Southern Africa is the world's largest emitter of smoke particles in the atmosphere, known as biomass-burning aerosols, from the burning of grasslands and other biomass. The project will help researchers better understand the effects of widespread biomass burning on Earth's climate. Scientists study the effect of smoke particles on Earth's climate

The study will investigate how smoke particles flowing far offshore from the African continent affect the remote and cloudy southeast Atlantic climate. Smoke, which absorbs sunlight, is a warming agent in the climate system when located above a bright surface, such as clouds. The smoke overlying the southeast Atlantic provides one of the largest aerosol-based warming of climate on the planet, since the region is also home to one of the largest low-cloud decks on the planet.

"Ascension Island is an ideal location since it is very remote and allows us to sample the smoke after it is well-aged, about which less is known," said Paquita Zuidema, professor of atmospheric sciences at the UM Rosenstiel School and principal investigator of the research experiment. The long deployment time will allow us to characterize the marine low clouds both with and without the presence of smoke. This is ultimately valuable for understanding the <a href="http://www.earth.com/video/earth-from-space-houston-texas/">Earth's</a> energy balance."

By evaluating how the low clouds respond to the presence of sunlight-absorbing aerosols, scientists can better understand low cloud behavior, which is currently an uncertainty in model predictions of future climate, since no fundamental theory on low cloud processes is yet in place.

Low clouds dominate the atmosphere over the southeast Atlantic Ocean all year. Bright white cloud appears darker when viewed from above when smoke is present. The southeast Atlantic overall is brighter, not darker when smoke is present, suggesting that the clouds become thicker and more extensive when smoke is present.

Zuidema received a $365,050 seed grant from the U.S. Department of Energy to plan the study. And a $440,225 grant from NASA which further supports related aircraft investigations as part of the NASA Earth Venture Suborbital-2 ORACLES project.

NASA will complement the DOE surface-based measurements with airborne experiments during a month of each year in 2016-2018. This will allow researchers to take airborne samples of smoke particles as it ages, information that will improve satellite retrievals of this mixed smoke-cloud regime. The United Kingdom will also participate with its research aircraft, and French, Namibian, and South African scientists will collect and interpret aircraft and ground-based measurements closer to the Namibian coast.

The UM Rosenstiel School-led research team will study how smoke is transported through the atmosphere and across the Atlantic, how the aerosols change when transported, and the response of the low-lying clouds to the smoke. The information from the experiments will ultimately be used to improve global aerosol models and climate change forecasts.

Big Sur Coast Of California

PRISM instrument brings coasts and coral into focus. A coastal scene with deep blue seas and a coral reef is beautiful to look at, but if you try to record the scene with a camera or a scientific instrument, the results are almost always disappointing. Most cameras can't "see" underwater objects in such scenes because they're so dim and wash out the glaring seashore. These problems don't just ruin vacation photos. They're a serious hindrance for scientists who need images of the coastline to study how these ecosystems are being affected by climate change, development and other hazards.

To the rescue: the new Portable Remote Imaging Spectrometer, created at NASA's Jet Propulsion Laboratory, Pasadena, California. PRISM is an <a href="http://www.earth.com/news/far-uvc-light-kills-99-9-percent-of-airborne-coronaviruses/">airborne</a> instrument designed to observe hard-to-see coastal water phenomena. In NASA's upcoming Coral Reef Airborne Laboratory (CORAL) field experiment, PRISM will observe entire reef ecosystems in more of the world's reef area – hundreds of times more -- than has ever been observed before.

"Coastal ocean science has specific requirements that had not been met with other instruments" when PRISM was initially proposed, said Pantazis Mouroulis of JPL, who designed the instrument. "At that time, it was not even known whether anyone could design an instrument with those characteristics. We had to devise new techniques for assembling and aligning the instrument, and even new technologies for the components."

With devastating coral bleaching taking place around the world, a sensor that can collect a detailed, uniform, large-scale dataset on coral reefs could hardly be more timely. "The value of doing this investigation right now is unimaginable because of the speed at which the environment is changing, and PRISM is the perfect instrument at the perfect time," said JPL's David Thompson, who is designing a computer model to use with PRISM's measurements for CORAL. "It's such a sensitive instrument -- beyond anything I've worked with before."

How it works

The PRISM instrument is a spectrometer, an instrument that splits light into its spectrum of wavelengths and measures the intensity of the light at each individual wavelength. Every type of molecule absorbs a unique combination of wavelengths, leaving dark gaps in the spectrum of light. The pattern of gaps is a sort of spectral "bar code" for that molecule. Spectrometers collect light and record these spectral patterns in it.

PRISM's spectrometer collects spectra in the visible, ultraviolet and near-infrared wavelengths, which encompass the "bar codes" for most phenomena of interest along coastlines. Because it is an airborne instrument, PRISM can measure wide swaths of coastline repeatedly in a short period of time -- important when monitoring rapidly changing conditions such as rising floodwaters -- and it creates a dataset on a regional scale, but with an amount of detail approaching what can be collected by boat-based campaigns. Boat campaigns can only produce local-scale datasets, because they are so expensive and labor intensive.

PRISM measures all spectra in the entire scene below its airborne perch. Each airborne campaign that uses the instrument can select just the spectra it needs for its area of study. For the CORAL campaign, "We're after that fraction of light that makes it all the way to the bottom of the ocean and comes back to the sensor, which carries the signal of the health of the coral reef," said Thompson. Thompson designed his computer algorithms to eliminate the unneeded light and isolate just the seafloor spectra. "You can think of it as peeling back the layers of an onion," he said. "Atmospheric haze is different from the surface glint off the ocean, which is different from light that's gone partway down into the ocean, which is different from light that's gone all the way down [to the seafloor and back]. All those other optical paths have to be eliminated in our modeling."

To test Thompson's model, the light from each "onion layer" is compared against measurements of the same thing -- the amount of atmospheric haze and the light-changing properties of the ocean water, for example -- taken aboard boats at a few points along the plane's path at the same time the instrument flies overhead. "It's critical for the math [in the model] to be tied down at different points with actual, physical measurements," Thompson said. When a shipboard measurement of the water's murkiness agrees with the model's calculation of the same thing, for example, it gives confidence that the model is correctly interpreting the spectra collected by PRISM.

How it's working

Heidi Dierssen, an oceanographer and professor at the University of Connecticut, Groton, and co-investigator in the CORAL campaign, worked on the development of PRISM and took the instrument on its first field campaign to study eelgrass in California's coastal waters. Dierssen has used many different instruments to gather coastal data in the past. When she used sensors that were optimized for land to observe the ocean, "They failed to give us good signals," she said. "When you looked at a spectrum it was often wavy, and you had to spend a lot of effort to calibrate it to what you measured in the water." When she used PRISM, "I was shocked," she said. "The first time we collected imagery, we got very good agreement with the field data. That instrument is truly a leap forward."

CORAL's project scientist, Michelle Gierach of JPL, has seen PRISM's data from Dierssen's study and used the instrument to observe ocean color (which can indicate phytoplankton presence) in the sea around Antarctica last winter. "We have only begun to scratch the surface of what PRISM is capable of doing, from eelgrass to biology within the Southern Ocean to now assessing coral reefs throughout the western tropical Pacific," she said. "Those are just some of the things that PRISM has in its arsenal. There's so much more that is possible."

NASA uses the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future. NASA uses airborne and ground-based instruments to develop new ways to observe and study Earth's interconnected natural systems. The agency freely shares this unique knowledge and works with institutions around the world to gain new insights into how our planet is changing.

California Drought

Slow-moving landslides reflect California's drying climate. Merged data from on-the-ground measurements, aerial photography, satellite imagery and satellite-radar imaging have unveiled an unexpected geological consequence of northern California's ongoing drought.
<div>

Initially, University of <a href="http://www.earth.com/news/unequal-treatment-protestors/">Oregon</a> scientists were perplexed by new satellite data that indicated that trees and rocks atop 98 slow-moving landslides in northern California's Eel River Basin were no longer flowing at historical rates seen between 1944 and the turn of the century. Many of the formations, they could see, had barely moved in the last three years.

"We realized that this slowing down of the landslides was a massive signature of California's drought," said Joshua Roering, a professor in the UO Department of Geological Sciences. "Finding this was an accident. We didn't set out to connect our research to climate. We discovered this by being frustrated by the data."

The research, led by Roering's postdoctoral researcher Georgie L. Bennett, is detailed in a paper accepted for publication in the journal Geophysical Research Letters. The findings, she said, are important to scientists monitoring landslides worldwide, including at similar sites she has visited in Italy.

Many Eel River Basin landslides have been slowly moving for thousands of years. The new study shows that the landslides, based on the 10 most-scrutinized landslides, slowed by half twice between 2009 and 2015, a period when the region experienced unprecedented drought.

Rates of historical movement vary by the size and depth of individual formations, Roering said, adding that, in general, the landslides had averaged "a few feet" annually. Small landslides are more sensitive to seasonal periods of rainfall and drought, while larger landslides more likely average out impacts from climate variability, the researchers found.

"Landslides move highways and make things really difficult for engineers all over the western U.S., and all over the world," Roering said.

Understanding the interior plumbing of landslides, especially how moisture affects "the conveyor belt" that keeps them moving along the surface is vital to maintaining safety and for projecting conditions that may indicate a catastrophic collapse that could dam a river or destroy a highway, he said.

"The landslide outflows we studied are typical in many places in the world," said Bennett, now a postdoctoral research associate with the U.S. Forest Service and Colorado State University. "This paper is important to helping understand how landslides respond to rainfall, and it provides data that should eventually help in terms of forecasting how landslides will respond to climate change. Smaller outflows are more sensitive to increasing or declining amounts of precipitation."

The study area covered an 86-square-mile stretch along the 200-mile-long river, which meanders through the coastal mountain range from just north of California's wine country to near Fortuna, where it meets the Pacific Ocean.

Data collection on such a scale had not been done before, Roering said. "The difference here is the amount of data we looked at," he said. "People have been putting equipment on landslides and watching them for years -- long before GPS and lasers. We were able to do this on a massive scale. This was a systematic look at the whole landscape -- what it's doing -- not just of one feature."

Researchers found that the rocks and soil have dried substantially, based on groundwater data gathered at one of the locations. The current lack of moisture, Roering said, means there is no longer enough lubrication to allow for movement.

This summer, his team, in collaboration with a team led by UO seismologist Amanda Thomas, will place 80 small seismometers in various locations on one of the landslides. The project aims to locate the underlying water table.

"A question now is how much water will it take, and how long will it take to get water down the depths at the base of these sliding surfaces to reduce the friction and get them to start moving again," Roering said. "The site we will be instrumenting should help us better understand the structure and plumbing of landslides."

Data merged in the research came from manual measurements of movement based on tracking trees as they surfed on the surface of earthflows between aerial photographs from 1944 to 2006 and from automatic measurements obtained through satellite pixel tracking from high-resolution imagery spanning 2009-2015. The satellite tracking was validated using the remote sensing technology interferometric synthetic aperture radar (InSAR).

Bennett, who soon will join the faculty at the University of East Anglia in England, compared the data on landslide movement from 1944 onward with an index of drought known as the Palmer Drought Severity Index.

What happens to hydraulic fracturing wastewater on cropland. The use of hydraulic fracturing, or "fracking," has grown rapidly in the U.S. over the past 15 years -- but concerns persist that the oil and gas extraction method could harm the environment and people's health. To better understand its potential effects, scientists simulated what would happen to the wastewater produced by the technique after a spill. They published their findings in the ACS journal Environmental Science &amp; Technology.

This spring, the U.S. Energy Information Administration estimated that hydraulic fracturing accounts for two-thirds of the country's natural gas production. Customers have benefited from lower gas bills, but the technique's growth comes with some risks. The <a href="http://www.earth.com/image/cameron-peak-fire-is-now-the-largest-in-colorados-recorded-history/">Colorado</a> Oil and Gas Conservation Commission received reports of 838 spills that released a total of more than 660,000 gallons of fluids associated with fracking in 2014. Since hydraulic fracturing and, potentially, any associated spills often occur near agricultural land, Jens Blotevogel, Thomas Borch and colleagues wanted to find out whether compounds in the wastewater biodegrade or stick around in the soil where they might be taken up by crops.

The researchers tested the fates of three common hydraulic fracturing additives in agricultural topsoil. The surfactant polyethylene glycol completely degraded within 42 to 71 days. But the surfactant did not break down when combined with another hydraulic fracturing additive called a biocide at a salt concentration typical for wastewater produced during oil and gas extraction. The researchers say their findings highlight the need for further testing to better understand spills' potential effects on crops and the environment.

Antarctic coastline has been losing ice for 40 years. Part of Antarctica has been losing ice to the ocean for far longer than had been expected, satellite pictures reveal.
<div>

A study of images along 2000km of the West <a href="http://www.earth.com/news/antarctica-is-melting-faster-than-models-predict-due-to-climate-variability/">Antarctica</a> coastline has shown the loss of about 1000km2 of ice - an area equivalent to the city of Berlin - over the past 40 years.

Researchers were surprised to find that the region has been losing ice for such a length of time. Their findings will help improve estimates of global sea level rise caused by ice melt.Antarctic coastline has been losing ice for 40 years

A research team from the University of Edinburgh analysed hundreds of satellite photographs of the ice margin captured by NASA, the United States Geological Survey (USGS) and the European Space Agency (ESA).

They found that ice has been retreating consistently along almost the entire coastline of Antarctica's Bellingshausen Sea since satellite records began.

The team also monitored ice thickness and thinning rates using data taken from satellites and the air. This showed that some of the largest changes, where ice has rapidly thinned and retreated several miles since 1975, correspond to where the ice front is deepest.

Scientists suggest the loss of ice is probably caused by warmer ocean waters reaching Antarctica's coast, rather than rising air temperatures. They say further satellite monitoring is needed to enable scientists to track progress of the ice sheet.

Their study, published in Geophysical Research Letters, was carried out in collaboration with Temple University in the US. It was supported by the Carnegie Trust for the Universities of Scotland, the Natural Environment Research Council and the ESA.

Frazer Christie, a PhD student in the University of Edinburgh's School of GeoSciences, who co-led the study, said: "We knew that ice had been retreating from this region recently but now, thanks to a wealth of freely available satellite data, we know this has been occurring pervasively along the coastline for almost half a century."

Dr Robert Bingham, also of the School of GeoSciences, said: "This study provides important context for our understanding of what is causing ice to retreat around the continent. We now know change to West Antarctica has been longstanding, and the challenge ahead is to determine what has been causing these ice losses for so long."

Politics often pollutes support for pro-science environmental solutions. Mentioning politics in a message about an environmental issue may turn people -- even people informed about the issue -- away from supporting a pro-science solution, according to a team of researchers.

In a study, conservative participants who were asked to react to a message about excess water runoff showed lower support for an environmental science improvement project when the message was framed around global warming terminology, according to Lee Ahern, associate professor of advertising and public relations, <a href="https://www.bing.com/search?q=penn+state&amp;cvid=720ec3b10d00462588230c58584182e9&amp;FORM=ANAB01&amp;PC=HCTS">Penn State</a>. The effect was even stronger among those conservatives with more knowledge about the issue, he added.

"It's the framing of the issue that's really important," said Ahern. "This is really a message for scientists and science communicators: don't pollute and politicize the information environment around the issue, because once you do that, people's <a href="https://www.earth.com/news/climate-threats-iowa-political/">political</a> identities are going to get engaged."

This study, along with others, has established that having more knowledge about science does not necessarily translate into more support for pro-science policies, according to Ahern, who added that, in this case, the environmental solution was to add more green surface infrastructure, such as green roofs.

The researchers, who report their findings in a recent issue of Science Communication, suggest that a reader's political and social identities can be activated when politicized terms or concepts are used in a message. This activation may then cause people to withdraw support from solutions they may have backed.

"The issue with the public's support for pro-science solutions for things like global warming, in particular, as well as other environmental issues that have socially contested policy solutions, is that the political identity of the people who are thinking about these issues often becomes activated," said Ahern, who worked with Colleen Connolly-Ahern, associate professor of advertising and public relations, Penn State and Jennifer Hoewe, assistant professor of journalism, University of Alabama.

Ahern said that all political ideologies, not just conservatives, are susceptible to this type of motivated reasoning.

"This is not unique to conservatives," said Ahern. "It works both ways. Studies have been done on other issues, for example, nuclear power and genetically modified organisms, that have shown similar effects among liberals."

The researchers suggest that scientists hoping to reach consensus on solutions should avoid political rhetoric in their communication.

"This is really a message for the scientists, not necessarily the public," said Ahern. "It's interesting for people to understand what's happening, but the people who really need to change what they are doing are the scientists and science communicators."

The researchers recruited 964 participants to take an online survey on local water quality in the Philadelphia area. The participants were asked what political party they supported and how strongly they supported the party. They were also asked to respond to questions that would group them into a range of egalitarian-hierarchical or individualist-collectivist worldviews.

The researchers measured the participants' knowledge of storm water runoff issues in Philadelphia and also used a quiz from the National Science Foundation to test their general science knowledge.

The study had two conditions. A normal condition attributed the water runoff problem to excess rain, while the global warming condition framed the problems around climate change. Statements and phrases, such as "stopping global warming will require international agreements" and "human-caused global warming," were used to frame the subject around climate issues.

Among solid or strong Democrats in the global warming condition, participants with high knowledge reported stronger willingness to pay for environmental solutions, such as adding green roofs. Solid or strong Republicans with high knowledge, on the other hand, reported stronger support in the normal condition for the environmental solutions, but not in the global warming condition. They were even more resistant to the solutions than low-knowledge Republicans.

"In fact, support among the low-knowledge Republicans increased in the global warming condition," said Ahern.

Sentinel satellites give major support to environmental monitoring. The unprecedented frequency of Sentinel observations capture rapid changes in agricultural production from national to field scale, serving as a major support for environmental monitoring and agricultural subsidy control.

The Sentinel satellites of Europe’s environmental Copernicus programme are used, among other things, to study changes in farming on a weekly basis, with a 10 m resolution, and with a free and open data policy.

Europe’s Sentinel-1 and Sentinel-2 satellites allow us to observe subtle changes in land use. For instance, which crops are being grown and how fast or well they are developing, as well as spotting differences within single, larger fields. Sentinel <a href="https://www.earth.com/image/satellites-help-observe-glaciers-in-alaska/">satellites</a> give major support to environmental monitoring

This information can be used for different purposes – from predicting seasonal yields to preventing hunger in some parts of the world. Planning can help to mitigate an expected bad harvest, for example.

Agricultural mapping and monitoring is a key application for Earth observation because of its need for recurrent and frequent data, to produce seasonal and annual information on crop production.

The Sentinels are explicitly designed to support the implementation and monitoring of European policies, such as the Common Agricultural Policy (CAP) at national to regional scale.

The EU spends some 40% of its budget on agriculture subsidies, and whether farmers are declaring everything correctly can be checked through satellite data. The CAP aims to improve agricultural production and sustainable use of natural resources, while considering global issues such as food security and climate change.

At the recent Living Planet Symposium in Prague, ESA launched a national crop map, together with the EU’s Joint Research Centre and the Czech State Agriculture Intervention Fund, covering the Czech Republic.

“This Czech crop map is a key proof-of-concept, linking the free and open data streams from the Sentinels with Member State’s geographical data infrastructure to generate information for a broad community of users in agriculture,” says Guido Lemoine, from the Joint Research Centre.

This national presentation was conceived as a demonstration of what could be achieved in Europe, through the combined use of in-situ information from the Land Parcel Identification Systems (part of the CAP management), together with the dense time series from Sentinel-1 and Sentinel-2 satellites.

The frequent radar data coverage of Sentinel-1 alone was able to distinguish the seven main crop types in the country, including cereals, maize and rapeseed, through their distinct seasonal temporal behaviour, viewed in the data.

Lucie Šavelková from the State Agriculture Intervention Fund says, “The results of the Czech-Agri project are very promising for the implementation in daily activities of the Czech Paying Agency.

“These results indicate high potential of the use of Sentinel data in the agricultural sector, providing useful information in supporting the administration and control of the European Common Agriculture subsidies. “

Renáta Suchá, also from the Fund, adds, “The wide Sentinel data coverage means the outcomes of the activities can be monitored on the overall national and regional level, providing a framework for the analyses of impact of agricultural policies and activities on the environment.”

Wildfire on warming planet requires adaptive capacity. Industrialized nations that view wildfire as the enemy have much to learn from people in some parts of the world who have learned to live compatibly with wildfire, says a team of fire research scientists.
<div>

The interdisciplinary team say there is much to be learned from these "fire-adaptive communities" and they are calling on policy makers to tap that knowledge, particularly in the wake of <a href="https://www.earth.com/news/greenland-glaciers-face-a-triple-threat-from-global-warming/">global warming.</a>

Such a move is critical as climate change makes some landscapes where fire isn't the norm even more prone to fire, say the scientists in a new report published in a special issue of the Philosophical Transactions of the Royal Society B. Wildfire on warming planet requires adaptive capacity

"We tend to treat modern fire problems as unique, and new to our planet," said fire anthropologist Christopher Roos, Southern Methodist University, <a href="https://www.bing.com/search?q=dallas&amp;cvid=da09b3220f864c1b8ae22cc4ebf49e5c&amp;FORM=ANAB01&amp;PC=HCTS">Dallas,</a> lead author of the report. "As a result, we have missed the opportunity to recognize the successful properties of communities that have a high capacity to adapt to living in flammable landscapes -- in some cases for centuries or millennia."

One such society is the ethnically Basque communities in the French Western Pyrenees, who practice fire management to maintain seasonally flammable grassland, shrub and woodland patches for forage and grazing animals. But the practice is slowly being lost as young people leave farming.

Additionally, Aboriginal people in the grasslands of Western Australia use fire as part of their traditional hunting practices. Children begin burning at a very young age, and the everyday practice is passed down. These fires improve hunting successes but also reduce the impact of drought on the size and ecological severity of lightning fires.

Social institutions support individual benefits, preserve common good

Fire-adaptive communities have social institutions in place that support individual benefits from fire-maintained landscapes while preserving the common good, said Roos, whose fire research includes long-term archaeological and ecological partnerships with the Pueblo of Jemez in New Mexico.

"These institutions have been shaped by long-histories with wildfire, appropriate fire-use, and the development of social mechanisms to adjudicate conflicts of interest," said Roos, an associate professor in the SMU Department of Anthropology. "There is a wealth of tried and tested information that should be considered in designing local fire management."

The authors note that globally, a large number of people use fire as a tool to sustain livelihoods in ways that have been handed down across many generations. These include indigenous Australians and North Americans, South Asian forest dwellers, European farmers, and also hunters, farmers and herders in tropical savannahs.

Global Warming will likely bring new fire problems, more flammable landscapes

Global Warming will likely bring new fire problems, such as making some landscapes more flammable, Roos said. More effort will be required to balance conflicting fire management practices between adjacent cultures. Currently most fire-related research tends to be undertaken by physical or biological scientists from Europe, the United States and Australia. Often the research treats fire challenges as exclusively contemporary phenomena for which history is either absent or irrelevant.

"We need national policy that recognizes these dynamic challenges and that will support local solutions and traditional fire knowledge, while providing ways to disseminate scientific information about fire," Roos said.

The authors point out that one of the greatest policy challenges of fire on a warming planet are the international consequences of smoke plumes and potential positive feedbacks on climate through carbon emissions. Most infamously, wildfire smoke plumes have had extraordinary health impacts during Southeast Asian "haze" events, which result in increased hospitalization and mortality in the region.

Not all fire is a disaster; we must learn to live with and manage fire

Carbon emissions from wildfires can be as much as 40 percent of fossil fuel emissions in any given year over the last decade. Although only deforestation fires and land conversion are a net carbon source to the atmosphere, the contribution of wildfires to global carbon emissions is non-trivial and should be a formal component of international climate dialogs.

"It is important to emphasize that not all fire is a disaster and we must learn how to both live with as well as manage fire," said co-author Andrew Scott, earth sciences professor at Royal Holloway University of London.

The report, "Living on a flammable planet: interdisciplinary, cross-scalar and varied cultural lessons, prospects and challenges," was published May 23, 2016 by The Royal Society, the U.K.'s independent scientific academy.

Authors call for holistic study of fire on Earth

The authors are from the United States, Great Britain, Canada, Australia, South Africa and Spain. The synthesis emerged from four days of international meetings sponsored by the Royal Society - the first of its kind for fire sciences.

The authors advocate for greater collaboration among researchers studying all aspects of fire.

Pyrogeography -- the holistic study of fire on Earth, "may be one way to provide unity to the varied fire research programs across the globe," the authors write.

"Fire researchers across disciplines from engineering, the natural sciences, social sciences and the humanities need to develop a common language to create a holistic wildfire science," said Roos. "The magnitude of the wildfire challenges we face on a warming planet will demand greater collaboration and integration across disciplines, but our job won't be done unless we are also able to translate our research for policymakers, land managers, and the general public."

NASA satellite finds unreported sources of toxic air pollution. Using a new satellite-based method, scientists at NASA, Environment and Climate Change Canada, and two universities have located 39 unreported and major human-made sources of toxic air pollution.

A known health hazard and contributor to acid rain, sulfur dioxide (SO2) is one of six air pollutants regulated by the U.S. Environmental Protection Agency. Current, sulfur dioxide monitoring activities include the use of emission inventories that are derived from ground-based measurements and factors, such as fuel usage. The inventories are used to evaluate regulatory policies for air quality improvements and to anticipate future emission scenarios that may occur with economic and population growth.

But, to develop comprehensive and accurate inventories, industries, government agencies and scientists first must know the location of <a href="http://www.earth.com/news/air-pollution-has-increased-covid-19-deaths-by-at-least-15-percent/">pollution</a> sources.

"We now have an independent measurement of these emission sources that does not rely on what was known or thought known," said Chris McLinden, an atmospheric scientist with Environment and Climate Change Canada in Toronto and lead author of the study published this week in Nature Geosciences. "When you look at a satellite picture of sulfur dioxide, you end up with it appearing as hotspots - bull's-eyes, in effect -- which makes the estimates of emissions easier."

The 39 unreported emission sources, found in the analysis of satellite data from 2005 to 2014, are clusters of coal-burning power plants, smelters, oil and gas operations found notably in the Middle East, but also in Mexico and parts of Russia. In addition, reported emissions from known sources in these regions were -- in some cases -- two to three times lower than satellite-based estimates.

Altogether, the unreported and underreported sources account for about 12 percent of all human-made emissions of sulfur dioxide - a discrepancy that can have a large impact on regional air quality, said McLinden.

The research team also located 75 natural sources of sulfur dioxide -- non-erupting volcanoes slowly leaking the toxic gas throughout the year. While not necessarily unknown, many volcanoes are in remote locations and not monitored, so this satellite-based data set is the first to provide regular annual information on these passive volcanic emissions.

"Quantifying the sulfur dioxide bull's-eyes is a two-step process that would not have been possible without two innovations in working with the satellite data," said co-author Nickolay Krotkov, an atmospheric scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

First was an improvement in the computer processing that transforms raw satellite observations from the Dutch-Finnish Ozone Monitoring Instrument aboard NASA's Aura spacecraft into precise estimates of sulfur dioxide concentrations. Krotkov and his team now are able to more accurately detect smaller sulfur dioxide concentrations, including those emitted by human-made sources such as oil-related activities and medium-size power plants.

Being able to detect smaller concentrations led to the second innovation. McLinden and his colleagues used a new computer program to more precisely detect sulfur dioxide that had been dispersed and diluted by winds. They then used accurate estimates of wind strength and direction derived from a satellite data-driven model to trace the pollutant back to the location of the source, and also to estimate how much sulfur dioxide was emitted from the smoke stack.

"The unique advantage of satellite data is spatial coverage," said Bryan Duncan, an atmospheric scientist at Goddard. "This paper is the perfect demonstration of how new and improved satellite datasets, coupled with new and improved data analysis techniques, allow us to identify even smaller pollutant sources and to quantify these emissions over the globe."

The University of Maryland, College Park, and Dalhousie University in Halifax, Nova Scotia, contributed to this study.

Better forecasting model for renewable electricity. The sun does not shine and the wind does not blow with constant intensity. This is a problem for the power grid, where the power supply must always match the power demand. In the EWeLiNE project, Fraunhofer and the German Weather Service have been working to develop better models for forecasting the generation of renewable electricity. Now they have launched a platform for transmission system operators to test the new models live.

In the EWeLiNE project, the Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) in Kassel is working together with Germany‘s National <a href="http://www.earth.com/news/china-captures-nearly-half-of-its-annual-co2-emissions/">Meteorological</a> Service in Offenbach. The partners develop mathematical models that produce improved forecasts accurate for each quarter-hour, which show how much electricity Germany’s installed photovoltaic and wind-farm facilities will generate over the next few hours and days. “It’s crucial for us to interconnect both worlds – forecasts of weather and power – more closely than before, tailoring them better to the requirements of the transmission system operators,” says project manager Dr. Malte Siefert of IWES, describing the added value of the new models. These companies operate the major power lines in Germany that make up the 380- and 220-kV high-voltage grid. Transmission system operators are responsible for bringing electricity to consumers, maintaining the power grid, and expanding it as needed.

EnergyForecaster: Testing forecast models live

The project began at the end of 2012. Now the partners are releasing a demonstration platform called the EnergyForecaster, where transmission system operators can try out new forecasting tools live in their control centers. The companies know nearly precisely when and how much electricity consumers need over the course of the day – but they know only approximately how much photovoltaic systems and wind farms will feed into the grid. “It’s important to forecast how much renewable power will be generated, because that tells us how much conventional generation capacity – whether nuclear, gas, or coal – needs to be brought online. At the same time, the forecast is necessary for calculations to keep the power grid stable and for trading electricity,” explains Siefert.

New kinds of forecasts available in the demonstration platform help transmission system operators calculate precisely how much wind and solar power will be fed into which grid nodes. Other new tools feature information on the reliability of the forecasts. “The transmission system operators also have to be aware of any critical weather conditions – for example, patches of low stratus or low-pressure zones – so they can better analyze and estimate the forecast results,” says Siefert. The researchers also benefit from the EnergyForecaster, as it shows them how their innovations perform in the real world. “We believe that more potential for optimization, as yet unrecognized, will result,” says Siefert.

1.9 million units included

“It’s crucial to calculate precisely how the 1.9 million photovoltaic facilities and wind farms operating in Germany will convert the weather into electricity,” says Siefert. The problem is that data are not available for all of the systems. “In some cases, data privacy laws prevent us from gaining access, while in others we simply lack the technology to continuously record how much power the unit feeds in,” explains Siefert.

IWES is designing mathematical models to improve the forecasts of all PV systems and wind farms in Germany. Researchers reconcile the results with existing data and optimize them for various applications. The scientists separate the more than 40 forecasts that transmission system operators currently use into 16 groups, then systematically improved them. “Our objective is to combine several different methods for each application to take advantage of their various strengths,” says Siefert.

Meanwhile, the DWD is adapting its weather forecasts to meet the requirements of power forecasting. “We performed detailed meteorological analyses of the occasions when forecasts of power feed-ins to the grid proved most inaccurate. From these analyses we then derived improvements to our weather models,” explains the DWD’s Dr. Renate Hagedorn. “With the systematic adaptation of our weather forecasts as a basis for wind and photovoltaic power forecasts for the electric grid, the German weather service has taken on a new and supplementary role,” explains Hagedorn.

Colorado is imposing higher fines on energy companies. Colorado is imposing heftier fines on energy companies as the state struggles to resolve conflicts between growing cities and big oilfields at their doorstep, an Associated Press analysis shows.
Regulators say the tougher penalties for breaking health, safety and environmental rules are prompting energy companies to be more careful. Others say it's too early to call them a success.
The higher fines kicked in a year ago after lawmakers said Colorado's existing penalties were too light. The AP reviewed records for the first 12 months under the new system, from April 2015 through March 2016, and found regulators levied 74 fines totaling $5.3 million - both higher than any calendar year for the previous 20 years.
Regulators also handed out Colorado's largest single oil and gas fine in at least 21 years, $1.3 million for a series of leaks at facilities owned by Benchmark Energy in a remote part of the state.
That fine probably would have been around $500,000 under the old system, said Matt Lepore, director of the Colorado Oil and Gas Conservation Commission, which regulates the industry.
Lepore said he doubts Benchmark will be able to pay the fine because it's a small operation. Companies that don't pay can lose permits they need to do business in the state.
Benchmark officials didn't return phone messages seeking comment.
The new penalty system raised the maximum daily fine from $1,000 to $15,000 and eliminated a fine cap of $10,000 per violation. Although there is no ceiling now, fines must be commensurate to the infraction, Lepore said.
Each state sets its own rules and fines for the energy industry, and no nationwide data could be found for comparison.
In Colorado, energy companies are policing themselves to avoid bigger fines, Lepore said
"I would surmise that operators are being more careful for fear of a substantial fine," Lepore said. "We aren't seeing sort of careless mistakes and careless noncompliance."
But companies also are fighting harder in the commission's hearing process if they are accused of a violation, he said.
Colorado ranks only seventh among energy-producing states, but tensions between the industry and its critics are high because cities and oilfields sometimes overlap, putting drilling rigs, wells and storage tanks near homes and schools.
The state's vigorous environmental groups also fight hard to keep energy development out of wilderness, recreational and residential areas.
A 2014 law revamping the fine system was one attempt to reduce the tension. Democratic state Rep. Mike Foote, who shepherded the bill through the statehouse, said the last time the fines were changed was when Dwight Eisenhower was president, from 1953 to 1961.
It's too early to declare victory under the new system, Foote said.
"I'm encouraged that the (Oil and Gas Conservation Commission) is enforcing the rules in a more diligent way," he said. "On the other hand, I'm discouraged that some operators continue to break those rules."
The Colorado Oil and Gas Association, an industry group, supported the higher fines.
"Only an industry that knows it works in a safe and compliant manner would have worked to increase penalties and enforcement on itself," association president Dan Haley said in an email.
"As with any industry and government, there are instances where mistakes do happen and violations occur, and we must hold ourselves accountable," Haley said.
The number and size of fines rose despite the industry's doldrums. Only 16 rigs were drilling new wells in Colorado in mid-May, down from 81 in late 2011, according to Baker Hughes Inc., an oilfield services company.
But Lepore pointed out Colorado still has 54,000 existing wells producing oil and gas that require state inspectors' attention.
Colorado has taken other steps to address conflicts over oil and gas development, hiring more field inspectors and attorneys to enforce the rules.
Lepore said the beefed-up legal staff is the primary reason the number of fines is rising, because cases move through the process faster.
The increased fines are welcome news but not the end of the debate, said Pete Maysmith, executive director of Conservation Colorado.
"This is not going to resolve the conflict, especially in many areas where energy development is happening," he said.

Marine National Monument coral reef destroyed by El Nino. El Nino's super warm water has turned what had been one of the world's most lush and isolated tropical marine reserve into a coral graveyard, federal scientists said Wednesday.

Researchers finishing an emergency undersea expedition found 95 percent of the coral dead around Jarvis Island in the Pacific Remote Island Marine National Monument . In November, much of the coral had bleached white but was alive. Marine National Monument coral reef destroyed by El Nino

"There's hardly anything left on the bottom in terms of the coral. It basically looks like a graveyard," said the expedition chief scientist Bernardo Vargas-Angel of the National Oceanic and Atmospheric Administration. "The skeletons are still there but they are covered with algae."

The algae was red, the color of blood or wine, and below it was a sea of dead coral, he said, returning from a 10-day diving expedition to the region along the equator, 1,400 miles southwest of Hawaii.

Scientists say the area around Jarvis Island is a special place that normally looks like something out of a technical color movie, vibrant with coral, plankton, fish and sharks. A unique ocean current normally brings cold water up from the deep, making it teem with life, said Woods Hole Oceanographic Institution scientist Anne Cohen, who is involved in the research but wasn't on this trip.

"It's like the Super Bowl of coral reefs, this place," Cohen said. "The coral cover is astronomical. The amount of life that it supports is just sky high: fish, turtle, dolphins, sharks. You name it, you find it there in large numbers."

The coral can normally survive short bouts of warm water but the water just got too warm for too long, scientists said. The water was about 7 degrees warmer than normal (4 degrees Celsius), Cohen said.

Scientists measure how warm the water is for coral in something called degree weeks. The record had been 18 degree Celsius weeks in 2014. This maxed out at 31.3, said NOAA coral reef coordinator Mark Eakin. It has been over 20 degree Celsius weeks for almost eight months, worse than anywhere else, Eakin said.

That warmer water is mostly from El Nino - the natural warming of parts of the Pacific that changes weather worldwide - assisted by man-made warming, Eakin said.

A study earlier this year found almost as much loss in a nearby island called Kiribati, but Eakin said this was worse.

"Just as I thought it couldn't get any worse, it does," Eakin said.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;



According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;



Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. 



Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.



Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today’s Video of the Day from <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes why experts are studying zebrafish to gain a better understanding of how the immune system responds to injury. Zebrafish have the ability to repair and regenerate organs.



“Organ regeneration offers an exciting opportunity for studying the immune system and to inquire why some species can regenerate organs like the heart or missing limbs while others like humans cannot,” explained Dr. Tatjana Piotrowski.



Zebrafish sensory organ hair cells are an ideal system to investigate the pathways and cell types involved in regeneration since they are easily destroyed with antibiotics and begin regenerating within five hours. This enabled the researchers to identify the exact timing and genetic programs for each anti-inflammatory macrophage activation state.&nbsp;



“Our hypothesis is that human macrophages do not receive the proper chemical activation 'cocktail' to instruct pro-regenerative processes,” said Dr. Nicolas Denans. “Identifying the molecular recipe of macrophage activation in zebrafish may one day enable us to design regenerative immunotherapies in humans.”&nbsp;&nbsp;&nbsp;



“The new evidence is a valuable resource for comparative studies on the genetic programs involved in macrophage-mediated repair and regeneration. In other words, different types of injuries may induce different kinds of inflammatory responses. We want to decipher whether this 'language' is universal or if there are a variety of dialects."

The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.
