Rice University engineers who mimic atom-scale processes to make them big enough to see have modeled how shear influences grain boundaries in polycrystalline materials.
Researchers in Japan have discovered that the local DNA motion inside of human cells remains steady throughout interphase, where the cell grows and replicates its DNA for cell division. The study suggests that this steady-state DNA motion allows cells to conduct housekeeping tasks under similar environments during interphase.
In the fall of 2017, geology professor Patricia Gregg and her team had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. One of the scientists on the Ecuador project, Dennis Geist of Colgate University, contacted Gregg, and what...
Aqueous droplet formation by liquid-liquid phase separation (or coacervation) in macromolecules is a hot topic in life sciences research. Of these various macromolecules that form droplets, DNA is quite interesting because it is predictable and programmable, which are qualities useful in nanotechnology. Recently, the programmability of DNA was used to construct and regulate DNA droplets formed by...
Carbon dioxide measured at NOAA's Mauna Loa Atmospheric Baseline Observatory peaked for 2022 at 421 parts per million in May, pushing the atmosphere further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.
Nothing I've read about the Baudet du Poitou donkeys prepares me for my first sight of them. They are girthy, with massive round bellies and oversized ears that swoop forward and back, sometimes independently of one another. They are covered in thick hair that hangs in shaggy tufts, "like mammoth fur," says my companion on this adventure in equine medicine, Public Affairs senior photographer...
Michigan State University chemists are discovering new information to help remediate "forever chemicals" by showing for the first time how they interact with soil at the molecular level.
The prospect that the U.S. Supreme Court could soon strike down its landmark abortion-rights decision in Roe v. Wade has galvanized some social media users—from Pennsylvania to Colorado, and New Jersey to Canada—to organize an unofficial abortion aid network for the internet age.
Narcissism, psychopathy and Machiavellianism are ubiquitous among CEOs, despite ample evidence that these dark personality traits pose financial and managerial risks to organizations. Their prevalence on corporate boards—nearly three times the general population—suggests that on some levels anti-social behavior may benefit business management. A new study published in the Strategic Management...
The year 2020 was marked by lockdowns as a result of the COVID-19 pandemic, as well as the killing of George Floyd by Minneapolis police and ensuing protests across the United States. A new study analyzed the effect of these events on crime rates in many of the largest U.S. cities. The study found that the pandemic and the protests were associated with significant changes in urban crime, but the...
Countries in which courts more easily enforce contracts see less economic volatility overall than nations that don't adhere as well to the rule of law. That's the finding from a study by a finance researcher at The University of Texas at Austin.
Personality is not unique to humans. New research published in the Royal Society Open Science journal demonstrates that zebra finches have personalities, and some traits are consistent over two years of the birds' lives.
Researchers from the Zoonosis Science Center at Uppsala University have identified a new coronavirus. Their study of approximately 260 bank voles caught around Grimsö, Örebro County, shows that the virus is well established in Sweden's red-backed voles.
Refugees increasingly receive money from humanitarian agencies and organizations, instead of food, clothing and other items shipped from afar. This approach is intended to let refugees get more of what they need while also boosting local businesses.
The mere thought of barbecue's smoky scents and intoxicating flavors is enough to get most mouths watering. Summer is here, and that means it is barbecue season for many people in the U.S.
Stress is common among teachers, and recent reports suggest it's getting worse. We need to understand the sources of this stress to improve support for teachers. Growing teacher shortages in Australia underscore the need for this support.
The recent mass shooting that killed 19 children and two teachers at Robb Elementary School in Uvalde, Texas, has sparked another round of the gun control debate.
Every so often stories of genetic theft, or extreme precautions taken to avoid it, make headline news. So it was with a picture of French President Emmanuel Macron and Russian President Vladimir Putin sitting at opposite ends of a very long table after Macron declined to take a Russian PCR COVID-19 test. Many speculated that Macron refused due to security concerns that the Russians would take and...
Food wastage in farm shops, agricultural cooperatives and farmers' stalls is between 1% and 2%, a much lower percentage than in supermarkets, where 5% to 10% of fruits and vegetables end up in the rubbish bin. This is the result of a study by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) carried out as part of a project that aims to...
Earth and ocean researchers at the University of Canterbury (UC) are using drones, satellite tracking and infrared sensors to improve ocean health.
On the way from the place of production to the consumer's plate, about one third of all food worldwide spoils. One reason is unfavorable storage conditions along production and supply chains, including suboptimal storage at home. Researchers at Empa's Biomimetical Membranes and Textiles laboratory in St. Gallen have been working for some time on digital solutions that could reduce this food waste....
Scientists who study the cosmos have a favorite philosophy known as the "mediocrity principle," which, in essence, suggests that there's really nothing special about Earth, the sun or the Milky Way galaxy compared to the rest of the universe.
Students are most likely to benefit from online credit recovery when it blends online instruction with face-to-face time, rather than being conducted fully online, according to research published by Carolyn J. Heinrich, chair of the Department of Leadership, Policy and Organizations and Patricia and Rodes Hart Professor of Public Policy and Education at Vanderbilt Peabody College of education and...
