A thermal power plant on the Aegean Sea was evacuated on Wednesday as a deadly wildfire that has ravaged Turkey for the past week reached its outer edge.

Researchers recently discovered a better way to make a new class of soft materials—reducing a process that used to take five months down to three minutes.

Ask any space explorer, and they'll have a favorite photo or two from their mission. For Kevin Hand, a scientist at NASA's Jet Propulsion Laboratory in Southern California and co-lead of the Perseverance rover's first science campaign, his latest favorite is a 3D image of low-lying wrinkles in the surface of Jezero Crater. The science team calls this area "Raised Ridges." NASA's Ingenuity Mars Helicopter captured the two shots for this stereo image on July 24 during its 10th flight.

Since receiving a $25 million grant in 2019 to become the first National Science Foundation (NSF) Quantum Foundry, UC Santa Barbara researchers affiliated with the foundry have been working to develop materials that can enable quantum information-based technologies for such applications as quantum computing, communications, sensing, and simulation.

This week, NASA's airborne Oceans Melting Greenland (OMG) mission begins its final survey of glaciers that flow from Greenland into the ocean. OMG is completing a six-year mission that is helping to answer how fast sea level is going to rise in the next five, 10, or 50 years.

Exploding stars generate dramatic light shows. Infrared telescopes like Spitzer can see through the haze and to give a better idea of how often these explosions occur.

Air quality on Toronto subway platforms has improved substantially with the rollout of new cars on Line 1, according to a new study by the University of Toronto's Faculty of Applied Science & Engineering and Health Canada.

Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially more dangerous. Among these invisible substances is uranium. Leaching into water resources from mining operations, nuclear waste sites, or from natural subterranean deposits, the element can now be found flowing out of taps worldwide.

Groups commonly targeted by voting restriction laws—those with low incomes, who are racial minorities, and who are young—are also less likely to be insured in states with more voting restrictions, according to a study by researchers at Columbia University Mailman School of Public Health and University of Alberta School of Public Health, Edmonton, Canada. However, those who are wealthier, white or older are no more likely to be uninsured, irrespective of the level of voting restrictions.

Polymer semiconductors—materials that have been made soft and stretchy but still able to conduct electricity—hold promise for future electronics that can be integrated within the body, including disease detectors and health monitors.

Recent record-breaking rainfall across the northeastern United States is part of a larger trend. From Maine to West Virginia, the Northeast has seen an abrupt increase in extreme precipitation—heavy rain and snow resulting in about 1 to 2 inches of water in a day depending on location since 1996, which has coincided with warming sea surface temperatures in the North Atlantic. Northeast extreme precipitation is typically caused by tropical cyclones, thunderstorms along fronts, and extratropical cyclones like Nor'easters. Читать дальше...

Researchers from Columbia University, University of Southern California, and Sotheby's published a paper in the Journal of Marketing that introduces a new tool that measures the relevance of academic marketing articles to marketing practice, both in terms of topical and timely relevance.

Researchers from Johns Hopkins Medicine say they have added to evidence that a protein called CaMKII improves strength, endurance, muscle health and fitness in young animals. Their experiments working with mice and fruit flies, however, found that the gene for CaMKII also contributes to an evolutionary tradeoff: increased susceptibility to age-associated diseases, frailty and mortality.

Tech culture often sees failure as essential. Facebook founder Mark Zuckerberg famously described the mindset as "move fast and break things."

An international team of researchers has found evidence of multiple waves of ancient brown bears migrating to the Japanese island of Honshu over vast periods of time. In their paper published in the journal Royal Society Open Science, the group describes their genetic analysis of tissue recovered from a brown bear skull found near Tokyo, and what they learned from it.

You probably remember your grade school science teachers explaining that energy can neither be created nor destroyed. That's a fundamental property of the universe.

The movements of ancient crop and animal domesticates across prehistoric Eurasia are well-documented in the archaeological record. What is less well understood: How Bronze Age farmers and herders incorporated newly introduced domesticates—like cows from southwestern Asia—into their long-standing animal husbandry and culinary traditions.

Since its isolation in 2004 by Geim and Novoselov from the University of Manchester (Nobel Prize in Physics in 2010), graphene has been termed a 'wonder material' due to its exceptional properties, which have already been exploited in many applications and products. However, the use of graphene in the form of tiny flakes in polymer composites limits the full exploitation of its excellent properties, requiring high filler loadings for achieving satisfactory electrical and mechanical properties.

Farmers around the world rely on antibiotics to keep livestock healthy, but increased bacterial resistance has created problems for both animals and humans. Instead of expensive new drugs, scientists have found a potential affordable solution that comes from nature. A new article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, details how bacteriophages could be a boon to farmers, especially those in resource-limited nations.

A novel route to tune and control the magnetic domain wall motions employing combinations of useful magnetic effects inside very thin film materials, has been demonstrated by researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) in Korea. The research, published in the journal Advance Science, offers a new insights into spintronics and a step towards new ultrafast, ultrasmall, and power-efficient IT devices.

To better estimate flood risks, risk maps should also consider historical data. This is recommended by researchers of CEDIM—Center for Disaster Management and Risk Reduction Technology of Karlsruhe Institute of Technology (KIT). CEDIM has now presented its first report on the flood disaster in Rhineland-Palatinate and North Rhine-Westphalia. As regards the role of climate change, the combination of more water available in the atmosphere and increasing permanence of general weather situations is associated... Читать дальше...

Empathetic people generally make better leaders, previous management research has shown, but there is one critical area where they might struggle compared to leaders who have lower levels of empathy—giving negative feedback.

Twenty natural strongholds would protect red squirrels in Scotland even if grey squirrels were to run rampant across the country, a new study shows.

An international team has observed an amazing phenomenon in a nickel oxide material during cooling: Instead of freezing, certain fluctuations actually increase as the temperature drops. Nickel oxide is a model system that is structurally similar to high-temperature superconductors. The experiment shows once again that the behavior of this class of materials still holds surprises.

Researchers at Sinai Health have used a tiny worm to track how an animal's brain changes throughout its lifetime, shedding new light on how human brains develop.
