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?

A group of conservation scientists and policy makers led by University of Adelaide researchers are calling for global action to combat the illegal timber trade.

They say governments and organisations responsible for protecting wildlife and forests around the world and certification schemes need to "catch up with the science" and put in place policies and frameworks to ensure the legality of timber being logged and traded around the world.

Consumers too need to play their part in demanding verification of the origin and legality of the timber items they buy, they say.

Illegal logging is a major cause of forest degradation and loss of biodiversity, and accounts for between an estimated 15-30% of the global trade in timber, worth US$30-100 billion annually.

The scientists have published their recommendations in the journal BioScience - detailing the range of scientific methods available for timber identification and how they can be applied within the timber supply chain. The work is a collaboration between the University of Adelaide, timber-tracking specialists Double Helix Tracking Technologies, the USDA Forest Service, INTERPOL and other research and forestry organisations.

The recommendations stem from work commissioned by the United Nations Office of Drugs and Crime in support of the UN Resolution 23/1 from May 2014 on "strengthening a targeted crime prevention and criminal justice response to combat illicit trafficking in forest products, including timber".

"We now have the scientific capability to identify and track illegally logged timber through the supply chain through DNA profiling, DNA barcoding and other means," says lead author Professor Andrew Lowe, from the Environment Institute at the University of Adelaide. "But now we need the policy and regulatory framework to incorporate scientific verification."

"Illegal logging is a huge problem globally, driven as much by demand from consumer countries (including Australia) as from producer nations," says co-author Dr Eleanor Dormontt, who was employed by the UN to write the recommendations.

"Our paper is the first to bring together the various scientific methodologies available for timber identification and consider how best they can be applied in timber supply chains to promote legality.

"We are all implicit in the exploitation of the world's forests, and even the most conscientious consumer has a reasonably high chance of purchasing or otherwise handling illegal wood products in their lifetime. Scientists, policy makers, NGOs, graders, foresters and the general public all have a part to play.

"The reality is that changes to timber supply chains can be made to improve their transparency, legality and sustainability. We need a coordinated international effort to make it happen."

Add cockatoos to the growing list of  species capable of making tools.

Researchers from the University of Veterinary Medicine in Vienna and the University of Oxford have shown that Goffin's cockatoos can make and use elongated tools of appropriate shape and length out of different materials, suggesting that the birds can anticipate how the tools will be used.

Tool manufacture was once regarded as a defining feature of mankind, but it is now known that a variety of animal species use and make their own tools. In nature, some of the most striking cases of tool-related behavior are seen not just among close relatives of Homo sapiens, such as chimps and other primates, but among birds including crows, vultures and Galapagos finches.

In all cases, what makes this possible is possessing the right combination of heritable and acquired competencies, as well as being capable of a degree of individual creativity. Goffin's cockatoos is a particularly interesting example for scientists to study, as it has unlikely to have a repertoire of inherited tool-related skills and relies more on innovation and problem-solving.

Goffin's cockatoos, which is native to Indonesia, is neither known to use tools in the wild nor to have evolved related abilities for manipulating twigs for other purposes such as nest building. One bird, called Figaro, previously displayed the ability to spontaneously (ie without training) make tools by biting long splinters out of the wooden beams of its cage, which he then used to rake pieces of food that were otherwise out of reach. Three others have since followed, showing that making such tools is within the capacity of the species.

While impressive, these feats do not prove sensitivity to the need for the tools to be of a particular shape: because wood is fibrous, biting and pulling actions naturally split it into the long, narrow pieces necessary to succeed. If individuals are capable of anticipating the requirements of each tool, they should be able to produce functional instruments by displaying different actions and using different materials.

To test if the birds were in fact aiming to make elongated tools that could bridge a particular distance, the researchers gave them the problem of reaching a piece of food placed a few centimeters beyond a circular hole in the transparent wall of a box. They were given four different materials that required different manipulations to produce suitable tools: larch wood (already familiar to them), leafy beech twigs (which had to be trimmed to be functional), cardboard (which, lacking a fibrous structure, could be cut into any shape and length), and totally amorphous beeswax.

Dr Alice Auersperg, who heads the Goffin Laboratory in the Messerli Research Institute at the University of Veterinary Medicine, Vienna, said: 'While none of the birds succeeded in making tools out of beeswax, we found that at least some of them could make suitable tools from the three remaining materials.'

The successful parrots made well-shaped tools, even though each material required different manipulation techniques. To make tools out of larch wood, they bit the material once or twice and tore off the resulting splinter. To use the leafy twigs, they snapped off redundant leaves and side branches until what was left was usable. Finally, to make cardboard tools they simply cut what was necessary from the edge of the sheet provided.

Dr Auersperg added: 'To us, the tools made from cardboard were the most interesting ones, as this material was not pre-structured and required the birds to shape their tools more actively. They succeeded by placing a large number of parallel bite marks along the edge of the material like a hole punch, using their curved upper beak to cut the elongated piece out of the cardboard block after reaching a certain length. Interestingly, this length was usually just above or very close to the minimum length required to reach the food reward placed behind the barrier.'

Co-author Professor Alex Kacelnik, from the University of Oxford's Department of Zoology, said: 'Ultimately, we want to understand how animals think - namely, to produce the equivalent of explicit computer programs capable of doing what the birds do. We really don't know if the birds can picture in their minds an object that doesn't yet exist and follow this image as a template to build something new, or how their brains elicit the appropriate set of movements to organize their response to novel problems, but this is what we are trying to find out.

'Studying tool-making in species like Goffin's cockatoos, which does not make tools naturally, is especially revealing, as these birds cannot do it by following pre-programmed instructions evolved to solve this specific problem. These cockatoos, like other parrots, offer wonderful research opportunities: their intelligence is flexible and powerful, they can solve physical and logical problems, they can learn from watching the behavior of others, they can learn about the surrounding objects by playing - and now it seems plausible that they can imagine which object would allow them to solve a new problem and go on to build it. I am sure that they will keep surprising us.'

President-elect Donald Trump is considering an oil billionaire and a North Dakota lawmaker for top posts as he moves to roll back President Barack Obama's environmental and energy policies and allow unfettered production of oil, coal and natural gas.
Trump has vowed to rescind "all job-destroying Obama executive actions" and pledges to sharply increase oil and gas drilling on federal lands while opening up offshore drilling in the Atlantic Ocean and other areas where it is blocked.
Topping Trump's to-do list is repealing the <a href="https://www.epa.gov/cleanpowerplan/clean-power-plan-existing-power-plants" target="_blank" rel="noopener">Clean Power Plan</a>, Obama's signature effort to limit carbon pollution from coal-fired power plants. The plan - the linchpin of Obama's strategy to fight climate change - is currently on hold awaiting a court ruling.
Trump also is targeting recent Obama administration efforts to reduce air and water pollution that have been opposed by Republicans and industries that profit from the extraction and burning of fossil fuels, including a rule to protect small streams and wetlands and ozone regulations designed to cut down on smog.
Those under consideration for energy secretary include Harold Hamm, an Oklahoma oil tycoon and leading proponent of fracking, and North Dakota Rep. Kevin Cramer, an early Trump supporter from a major oil drilling state, according to transition planning documents obtained by The Associated Press.
Venture capitalist Robert Grady, who worked in President George H.W. Bush's administration, is listed as a contender to lead both the Energy and Interior departments.
Cramer told reporters Monday he is happy to stay in Congress, especially "with a friend in the White House. And if another good friend like Harold Hamm would become secretary of energy, I'd feel like I won the lottery."
A coalition of conservative states has challenged both the Clean Power Plan and the water rule, which expanded the definition of waters protected under the <a href="https://www.epa.gov/laws-regulations/summary-clean-water-act" target="_blank" rel="noopener">Clean Water Act</a> to smaller non-navigable waters and seasonal tributaries.
The administration says the rule would safeguard drinking water for 117 million people, but Republicans and some Democrats representing rural areas say the regulations are costly, confusing and amount to a government power grab. Federal courts have put the rules on hold as judges review lawsuits.
Trump also is likely to move quickly to approve the Keystone XL oil pipeline from Canada, which Obama rejected last year. Trump highlighted the project at a campaign stop in Florida last month and listed it among his top priorities for the first 100 days of his administration.
Karen Harbert, president and CEO of the U.S. Chamber of Commerce's Institute for 21st Century Energy, said Trump can and will move quickly to overturn Obama's executive orders. From there, he will likely move to approve a new five-year plan that vastly expands offshore drilling and lift a moratorium on coal leasing on federal lands.
"If you have a good offense and a good defense you will win," Harbert said. Whoever Trump picks for key jobs will share his goals of "moving fast, changing the process which is not working now and getting things done," she said.
Obama said Monday that Trump should be in no hurry to make changes, citing U.S. progress on reducing carbon emissions even as the price of gasoline hovers nears $2 a gallon. Trump and his team "may want to take the country in a significantly different direction, but they've got time to consider what exactly they want to achieve," Obama said at a news conference.
Environmental groups don't plan to make Trump's job easy.
"We intend to fight like mad, both in the courts and in the streets, to resist any rollbacks by the Trump administration," said Michael Brune, executive director of the Sierra Club.
Some of those protests have already begun. Groups opposing the construction of an oil pipeline through the Midwest are planning more than 200 protest actions across the country Tuesday.
The Army Corps of Engineers said Monday it wants more study and tribal input before approving the $3.8 billion Dakota Access pipeline from North Dakota to Illinois. The Standing Rock Sioux says the pipeline threatens its drinking water and cultural sites.
Even as they gear up to oppose Trump, Brune said environmentalists may find some common ground with the president-elect. Renewable energy sources such as wind and solar power not only help fight climate change but are creating thousands of new jobs across the country, he said.
"If President-elect Trump is looking for a stimulus in energy he will find it in the solar and wind industries," Brune said.
Trump has said tax credits and other subsidies for wind and solar power "distort" the market, but says the U.S. should "encourage all facets of the energy industry," including wind and solar power, as a way to achieve energy independence.

Global carbon emissions flattened out in 2015, and are predicted to rise minimally in 2016, marking three full years of very low growth, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project.

The projected rise of only 0.2% for 2016 marks a clear break from the rapid emissions growth of 2.3% per year in the decade to 2013, with just 0.7 per cent growth seen in 2014.

The new data is published in the journal Earth System Science Data. It shows emissions growth remained below 1 per cent despite GDP growth exceeding 3 per cent.

Decreased use of coal in China is the main reason behind the 3-year slowdown.

Prof Corinne Le Quéré, Director of the Tyndall Centre at UEA who led the data analysis, said: “This third year of almost no growth in emissions is unprecedented at a time of strong economic growth. This is a great help for tackling climate change but it is not enough. Global emissions now need to decrease rapidly, not just stop growing.”

China – the biggest emitter of CO2 at 29 per cent – saw emissions decrease by 0.7 per cent in 2015, compared to growth of more than 5 percent per year the previous decade. A further reduction of 0.5 per cent is projected for 2016, though with large uncertainties.

The USA, the second biggest emitter of CO2 at 15 per cent, also reduced its coal use while increasing its oil and gas consumption and saw emissions decrease 2.6 per cent last year. USA emissions are projected to decrease by 1.7 per cent in 2016.

The EU’s 28 member states are the third largest emitter causing 10 per cent of emissions. The EU’s CO2 emissions went up 1.4 percent in 2015, in contrast with longer term decreases.

India contributed 6.3 per cent of all global CO2 emissions, with their emissions increasing 5.2 percent, in 2015 continuing a period of strong growth.

Although the break in emissions rise ties in with the pledges by countries to decrease emissions until 2030, it falls short of the reductions needed to limit climate change well below 2 degrees Celsius.

Prof Le Quéré said: “If climate negotiators in Marrakesh can build momentum for further cuts in emissions, we could be making a serious start to addressing climate change.”

The Global Carbon Budget analysis also shows that, in spite of a lack of growth in emissions, the growth in atmospheric CO2 concentration was a record-high in 2015, and could be a record again in 2016 due to weak carbon sinks.

Prof Le Quéré said: “Part of the CO2 emissions are absorbed by the ocean and by trees. With temperatures soaring in 2015 and 2016, less CO2 was absorbed by trees because of the hot and dry conditions related to the El Niño event. Atmospheric CO2 levels have exceeded 400 parts per million (ppm) and will continue to rise and cause the planet to warm until emissions are cut down to near zero.”

The Global Carbon Project’s estimation of global CO2 emissions and their fate in the atmosphere, land and ocean is a major effort by the research community to bring together measurements, statistics on human activities, with analysis of model results.

Prof Le Quéré stressed the need for reporting such as the Global Carbon Budget to inform decisions and actions on how to respond to climate change.

Dr Glen Peters of the Center for International Climate and Environmental Research in Norway, who co-authored the analysis, said: “Emissions growth in the next few years will depend on whether energy and climate policies can lock in the new trends, and importantly, raise the ambition of emission pledges to be more consistent with the temperature goals of the Paris Agreement.”

A Canadian natural gas plant could post more risk to salmon than previously believed if the project is allowed to go ahead, according to a new study.

The new research, conducted at the proposed site of a liquified natural gas plant on the Skeena River, found that the area is a popular destination for salmon. The fish spend a month or more in the spot to feed and grow before braving the trip out to sea, the study reported.

Dr. Jonathan Moore of <a href="https://www.sfu.ca/">Simon Fraser University</a>, who led the study, said the research shows the Skeena River estuary may be more valuable salmon habitat than originally believed. 

A previous marine fish survey, conducted on behalf of the natural gas plant project by <a href="http://www.stantec.com/">Stantec Consulting</a>, found the area to be a “low value” fish habitat. <a href="http://www.dfo-mpo.gc.ca/index-eng.htm">Fisheries and Oceans Canada</a>, the federal agency that manages Canada’s waterways, disagreed with Stantec’s conclusion, but the international energy coalition spearheading the gas plant project said that negative effects of construction could be mitigated.

The research team led by Moore used chemical signatures of sulfur, carbon and nitrogen left behind by fish as a sort of “chemical clock” to figure out how long they stayed in the estuary before heading out to sea.

The scientists found that about a quarter of Chinook salmon took a break in the estuary for 33 days, pink salmon vacationed about 30 days, and coho lingered for 22. Sockeye salmon only stayed in the estuary for about five days.

Knowing how long each species stayed in the stopover location would help environmental managers decide how important the area is to the fish, Moore said.

The research could cause another wrinkle for the gas plant, which is facing three lawsuits lodged by environmental groups and indigenous Canadians. Two of the three suits, filed in late October, laid out environmental activists’ concerns over the project’s environmental assessment process and the plant’s potential greenhouse gas emissions. 

The third, filed by the Gitanyow and Gitwilgyoots First Nations, claimed that indigenous Canadians were not well included in the project’s approval process.

Currently, the <a href="http://www.ceaa.gc.ca/default.asp?lang=en&amp;n=d75fb358-1">Canadian Environmental Assessment Agency</a> is allowing the project to proceed, provided it meets about 190 conditions set by the agency.

The salmon study was published on November 9 in the journal <a href="http://www.int-res.com/journals/meps/meps-home/">Marine Ecology Progress Series</a>.

Is there really scientific value in researching ticklish rats? There just might be, according to Dr. Michael Brecht and Dr. Shimpei Ishiyama of Berlin, Germany’s Bernstein Center for Computational Neuroscience.

In the late 1990s, researchers discovered that rats make noises while playing or being tickled, and wondered if those noises were similar to human laughter. Other animals have also shown signs of being ticklish, including dogs and chimpanzees.

Brecht and Ishiyama <a href="http://science.sciencemag.org/content/354/6313/757">decided to find out</a> if the rats were truly ticklish by monitoring their neural activity. 

After inserting wire electrodes into the rats to record their responses, they tickled the tiny creatures on their bellies, backs and tails. They also recorded the rats’ ultrasonic “laughter.”

They found that the rats had a good belly laugh and their sensory neurons fired intensely when they were tickled on, you guessed it, the belly. The back had less response, and the tail hardly any at all, indicating that, like humans, rats aren’t ticklish everywhere. 

They also tried the experiment in a few different conditions, and found that they (unsurprisingly) had less fun when they were tickled in anxiety-inducing situations, such as being under bright lights. Their chirp response was reduced and the fear may have reduced their sensory response.

So why bother? The researchers found that the rats were ticklish in some of the same spots as humans, showing that mammals might have some hard-wired neural responses related to tickling. 

They also found that the rats had similar responses – including their chirped laughter – when playing other games with researchers and each other. What does it mean? According to Brecht and Ishiyama, that tickling and the laughter that comes with it may have evolved as a form of social bonding through play.

The scientists looked at lab mice, which are less social than rats, and found that they were less than tickled by researchers attempts to induce a tickle response. In fact, they didn’t appear ticklish at all, and they don’t seem to play like rats, either, the researchers noted. 

That could connect to how other animals and even humans developed a response to being tickled. 

The study was published on November 11 in the journal <a href="http://science.sciencemag.org/">Science</a>.

Is one type of electric car better than another? That’s what researchers from <a href="https://www.stanford.edu/">Stanford University</a> and the <a href="https://www.tum.de/">Technical University of Munich</a> set out to determine when they compared electric cars that run off of hydrogen gas fuel cells to those that use rechargeable batteries.

According to the researchers, <a href="http://www.sciencedirect.com/science/article/pii/S0360544216311173">their study</a> offered an answer: battery-powered cars are both cheaper and more energy efficient for the immediate future, they said.

The study sought to help communities decide which type of electric car would be a better long-term investment, according to lead author Markus Felgenhauer, a doctoral student at the Technical University of Munich who previously studied at Stanford’s <a href="http://gcep.stanford.edu/">Global Climate and Energy Project</a>. 

To do that, the researchers considered how large-scale adoption of either battery-powered or fuel cell vehicles could affect community infrastructure. They focused their attention on Los Altos Hills, a small city in California, as a sort of case study to test their theories.

According to the research team, battery-powered electric cars are more economical because they are currently cheaper to buy, and can be charged by plugging into the existing electrical grid, no matter what type of energy a city uses.

Hydrogen fuel cells, however, must be refilled with hydrogen. The cost of installing electrolyzers that can convert solar energy or electricity from the grid to hydrogen would be a steep initial cost. 

Some have suggested that solar power could be converted and stored as hydrogen, and the excess could be used to power buildings, the research team said, but they found that not enough hydrogen is produced from solar power yet to make that a realistic goal. 

Taking in all of the costs of infrastructure, making batteries, and producing solar panels and electrolyzers, the battery-powered cars are the most cost effective at the moment, they said. 

Even so, if hydrogen fuel cell vehicles were much cheaper than battery-powered vehicles, they might be the better choice, Felgenhauer said. Currently, they are more expensive.

The study found that both types of vehicles could reduce overall carbon dioxide emissions.

The study was published in the journal <a href="http://www.journals.elsevier.com/energy">Energy</a>.

Fishing sustainably would increase fish catches by 57% in European waters, a marine conservation group said Tuesday.
<a href="http://www.oceana.org" target="_blank" rel="noopener">The Oceana environmental group</a> says scientists believe catches of haddock, cod, herring and sardine in the Atlantic could increase by at least 300 percent.
Group spokeswoman Maria Cornax said Tuesday there was "no excuse" not to start fishing sustainably.
"This is actually meant to help the fishery industry," she said. "They can get increased profits."
The European Commission, executive arm of the EU, has proposed maintaining or increasing the fishing quotas for 42 species which are rated in good health, and reduce catches for 28 stocks which are faring poorly. It said it based its suggestion on advisory bodies including the Copenhagen-based International Council for the Exploration of the Sea.
Oceana's research, which it billed as "the most comprehensive overview so far," was based on 397 stocks compared to around 150 monitored by the Commission.
Oceana published its findings before next month's EU meeting to set the 2017 fishing limits in the North Sea. Oceana said 85 percent of stocks were now "in an unhealthy state."
The study was led by a Germany-based <a href="http://www.geomar.de/en/" target="_blank" rel="noopener">GEOMAR Helmholtz Center for Ocean Research</a>.
Last month, the EU agreed to set tougher cod catch quotas in the western part of the Baltic Sea, but stayed well above targets sought by scientists who pushed for a cut of about 90 percent, and environmentalists who called for a temporary stop. EU fisheries ministers agreed on a 56 percent quota cut for the cod.

Global temperatures are soaring toward a record high this year, the U.N. weather agency said Monday, while another report showed emissions of a key global warming gas have flattened out in the past three years.
The reports injected a mix of gloom and hope at U.N. climate talks in Marrakech this week.
"Another year. Another record. The high global temperatures we saw in 2015 are set to be beaten in 2016," said Petteri Taalas, the head of the World Meteorological Organization.
WMO's preliminary data through October showed global temperatures, boosted by the El Nino phenomenon, are 1.2 degrees Celsius (2.2 degrees Fahrenheit) above pre-industrial levels.
That's getting close to the limit set by the global climate agreement adopted in Paris last year. It calls for limiting the global temperature rise since the industrial revolution to 2 degrees C or even 1.5 degrees C.
WMO said 16 of the 17 hottest years have occurred this century. The only exception was 1998, which was also an El Nino year.
Taalas said parts of Arctic Russia saw temperatures soaring 6-7 degrees C above average. "We are used to measuring global temperature records in fractions of a degree, and so this is different," he said.
Environmental groups and climate scientists said the report underscores the need to quickly reduce emissions of carbon dioxide and other greenhouse gases blamed for warming the planet.
Another report released Monday delivered some positive news, showing global CO2 emissions have flattened out in the past three years. However, the authors of the study cautioned it's unclear whether the slowdown, mainly caused by declining coal use in China, is a permanent trend.
"It is far too early to proclaim we have reached a peak," said co-author Glen Peters, a senior researcher at the Center for International Climate and Environmental Research in Oslo.
The study, published in the journal Earth System Science Data, says global CO2 emissions from fossil fuels and industry are projected to grow just 0.2 percent this year.
That would mean emissions have leveled off at about 36 billion metric tons in the past three years even though the world economy has expanded, suggesting the historical bonds between economic gains and emissions growth may have been severed.
"This could be the turning point we have hoped for," said David Ray, a professor of carbon management at the University of Edinburgh, who was not involved with the study. "To tackle climate change those bonds must be broken and here we have the first signs that they are at least starting to loosen."
Chinese emissions were down 0.7 percent in 2015 and are projected to fall 0.5 percent in 2016, the researchers said, though noting that Chinese energy statistics have been plagued by inconsistencies.
Peters said it's unclear whether the Chinese slowdown was due to a restructuring of its economy or a sign of economic instability, but the unexpected emissions reduction "give us hope that the world's biggest emitter can deliver much more ambitious emission reductions."
China, which accounts for almost 30 percent of global carbon pollution, pledged to peak its emissions around 2030 as part of the climate pact adopted in Paris last year. Many analysts say China's peak is likely to come much earlier - and may already have occurred.
"A few more years of data is needed to confirm this," said Bill Hare of Climate Analytics.
Even if China's emissions have stabilized, growth in India and other developing countries could push global CO2 levels higher again. India's emissions rose 5 percent in 2015, the study said.
The election of Donald Trump as president of the United States - the world's No. 2 carbon polluter - could also have an impact.
U.S. emissions fell 2.6 percent last year and are projected to drop 1.7 percent this year, as natural gas and renewables displace coal in power generation, the study showed. But it's unclear whether those reductions will continue under Trump, who has pledged to roll back the Obama administration's environmental policies, including the Clean Power Plan to reduce carbon pollution from power plants.
Obama's climate envoy, Jonathan Pershing, said Monday that China and other countries would move forward on climate action even if the U.S. reverses course under Trump.
"I'm hearing the same from the Europeans," he said. "I'm hearing the same from the Brazilians. I'm hearing the same from Mexico, and from Canada, and from smaller nations like Costa Rica and from Colombia."
Some researchers stressed that it's not enough for global emissions to stabilize, saying they need to drop toward zero for the world to meet the goals of the Paris deal.
"Worryingly, the reductions pledged by the nations under the Paris Agreement are not sufficient to achieve this," said climate scientist Chris Rapley of University College London.

Global temperatures are soaring toward a record high this year,...

China and other countries will stay committed to the Paris Agreement on climate change, irrespective of what the next U.S. administration decides to do, the outgoing U.S. climate envoy said Monday.
Jonathan Pershing told reporters at U.N. climate talks in Morocco he doesn't know what President-elect Donald Trump's "outlook" on climate policy will be. But Pershing said his Chinese counterpart, Xie Zhenhua, told him that China intends to move ahead regardless.
"Of course they are going to move forward," he said. "I'm hearing the same from the Europeans. I'm hearing the same from the Brazilians. I'm hearing the same from Mexico, and from Canada, and from smaller nations like Costa Rica and from Colombia."
Trump has called global warming a "hoax" on social media and promised during his campaign to "cancel" the Paris deal adopted last year. But many countries are hoping he will change his mind once in office.
"It is in the interest of the United States to deliver clean energy policies," said European Union Climate Commissioner Miguel Arias Canete.
Canete said he didn't want to speculate on "worst-case scenarios" such as the U.S. withdrawing from the Paris Agreement - the first in which all countries have agreed to take action on climate change.
"I prefer to be an optimist," Canete said.
He dismissed a proposal by former French president and current presidential candidate Nicolas Sarkozy for a carbon tax on American goods imported to the EU if the U.S. withdraws from the climate change deal.
"The European Commission is not thinking of making a proposal on that issue," Canete said.

The moon is a familiar sight in our sky, brightening dark nights and reminding us of space exploration, past and present. But the upcoming supermoon — on Monday, Nov. 14 — will be especially “super” because it’s the closest full moon to Earth since 1948. We won’t see another supermoon like this until 2034.

The moon’s orbit around Earth is slightly elliptical so sometimes it is closer and sometimes it’s farther away. When the moon is full as it makes its closest pass to Earth it is known as a supermoon. At perigree — the point at which the moon is closest to Earth — the moon can be as much as 14 percent closer to Earth than at apogee, when the moon is farthest from our planet. The full moon appears that much larger in diameter and because it is larger shines 30 percent more moonlight onto the Earth.

The biggest and brightest moon for observers in the United States will be on Monday morning just before dawn. On Monday, Nov. 14, the moon is at perigee at 6:22 a.m. EST and “opposite” the sun for the full moon at 8:52 a.m. EST (after moonset for most of the US).

If you’re not an early riser, no worries. “I’ve been telling people to go out at night on either Sunday or Monday night to see the supermoon,” said Noah Petro, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter (LRO) mission. “The difference in distance from one night to the next will be very subtle, so if it’s cloudy on Sunday, go out on Monday. Any time after sunset should be fine. Since the moon is full, it’ll rise at nearly the same time as sunset, so I’d suggest that you head outside after sunset, or once it’s dark and the moon is a bit higher in the sky. You don’t have to stay up all night to see it, unless you really want to!”

This is actually the second of three supermoons in a row, so if the clouds don’t cooperate for you this weekend, you will have another chance next month to see the last supermoon of 2016 on Dec. 14.

NASA scientists have studied the moon for decades. A better understanding of our moon helps scientists infer what is happening on other planets and objects in the solar system. “The moon is the Rosetta Stone by which we understand the rest of the solar system,” Petro said.

LRO has been mapping the moon’s surface and capturing high resolution images for more than seven years. Extensive mapping of the moon aids scientists in understanding our planet’s history, as well as that of planetary objects beyond the Earth-moon system.

“Because we have the Apollo samples, we can tie what we see from orbit to those surface samples and make inferences about what has happened to the moon throughout its lifetime,” Petro said. “The samples tell us how old certain lunar surfaces are, and based on the number of impact craters on those surfaces, we can estimate the ages of the rest of the moon. Furthermore, we can then apply those models to estimate the ages of surface on other planets in our solar system — all by studying the moon!”

When it comes to carbon storage, scientists have put a price tag on the value of mangrove forests in South Florida's Everglades -- and it's in the billions.

Mangrove forests absorb carbon dioxide, and much of that carbon remains trapped in the trees' biomass. Based on a scientific cost estimate, the stored carbon is worth between U.S. $2 billion and $3.4 billion. The billion-dollar price tag reflects the cost of restoring freshwater flow to areas that need it most, preserving the Everglades' mangroves.

That's a relatively small price when considering the cost to society if, rather than being stored, the carbon were released into the atmosphere, according to researchers at Florida International University (FIU).

Their results are published in the journal Environmental Science and Policy. The study was funded by the National Science Foundation's (NSF) Water, Sustainability and Climate Program and the NSF Florida Coastal Everglades Long-Term Ecological Research (LTER) site.

"If there isn't enough freshwater flowing through the Everglades, we may eventually lose some of the mangroves," said Mahadev Bhat, a scientist at FIU and co-author of the journal paper. "Once you let stored carbon out, that same carbon can lead to increased global warming and cost society a lot more."

In addition to removing excess carbon dioxide from the air, mangroves provide other benefits, including flood control, storm protection and good water quality.

"This finding is an excellent example of how research at long-term ecological research sites can inform management and policy decisions and help in making wise choices, in this case, how to mitigate the effects of increasing carbon dioxide in the atmosphere," said David Garrison, LTER program director in NSF's Division of Ocean Sciences.

The mangrove forests of the Everglades are the largest in the continental United States. Although protected, Everglades mangroves are affected by sea level rise, hurricanes, alterations in water flow and other changes.

"While our understanding of the Everglades is strengthened by this study, we need to remember that threats to this valued resource come from both saltwater intrusion and sea level rise," said Tom Torgersen, director of NSF's Water Sustainability and Climate program. "Management and policy decisions need to reflect the value of the Everglades, as well as the issues facing Florida."

According to the FIU researchers, preventing the loss of stored carbon in mangroves could become a critical component of the nation's climate change mitigation strategies.

"Having an inventory of the stored organic carbon and its potential economic value is key to designing strategies that secure funding for conservation and research work," said Meenakshi Jerath, lead author of the paper and a researcher at FIU's Extreme Events Institute. "It could, more importantly, further awaken public interest in and understanding of mangroves' socioeconomic importance."

Added John Schade, LTER program director in NSF's Division of Environmental Biology: "This research is a reminder of the valuable services mangroves provide, and the global benefits that can come from restoring and preserving them."

The study was conducted in collaboration with researchers at Louisiana State University and the NASA Jet Propulsion Laboratory.

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.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.



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;

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."

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



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."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;

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.
