Birds do it. Bees do it. Even spiders in their webs do it: cooperate for more peaceful colonies.

As climate change is expected to lead to more frequent periods of drought, researchers are increasingly working to make discoveries that can help plants adapt to prolonged water stress.
Academic conferences provide invaluable opportunities for researchers to present their work and receive feedback from attendees during question-and-answer sessions. Women are less likely to ask questions during these sessions, however, and research in Psychological Science suggests that this may be due to anxiety about how colleagues will receive their comments.
"Job burnout" is a term that's far too familiar to many people. A 2020 Gallup poll showed that 76 percent of employed Americans surveyed have experienced burnout.
The Louisiana State University (LSU) Campus Mounds sit on high ground overlooking the Mississippi River floodplain and have been a gathering place and destination for people for thousands of years. They are some of the oldest mounds in Louisiana and North America.
Motion is everywhere in living systems and is necessary for mechanical functions in artificial systems, such as robots and machines. Functional mechanical structures that can change volume and shape in response to external stimuli (such as light, heat, electricity, humidity, and chemistry) have a wide range of application prospects in the field of biomechanics and bionic robots. They have...
Researchers have developed a new computer framework that holds promise in the work to discover new drugs. Their framework uses an artificial intelligence method called a convolutional neural network to provide global information about potential novel drug candidates.
Children have become less physically active in school, despite teachers recognizing the importance of daily movement. Now, a new study published in BMC Public Health reveals the implementation of Ontario's Daily Physical Activity (DPA) policy is in sharp decline. The reasons, according to the study, include time constraints and low confidence among teachers about their ability to implement the...
Astronomers on a historically ambitious and massive galaxy-mapping mission have activated more than 10,000 amateur scientists in 85 countries to help in their quest. Now they hope to significantly scale up their volunteer force for a unique project that could reveal for the first time the nature of dark energy.
Much of U.S. criminal justice policy focuses on recidivism, and probation and parole violators make up a considerable share of jail and prison populations. In a new article, a 2022 winner of the Stockholm Prize in Criminology argues that to understand desistance—the process of reducing or ending criminal behavior—we must consider the role of individuals' cognitive transformations.
Researchers in the Center for Photochemical Sciences at Bowling Green State University have developed a coating system that shows promise in preserving historical monuments—and possibly much more.
Physicists at Google Quantum AI have used their quantum computer to study a type of effective particle that is more resilient to environmental disturbances that can degrade quantum calculations. These effective particles, known as Majorana edge modes, form as a result of a collective excitation of multiple individual particles, like ocean waves form from the collective motions of water molecules....
Numerous plastics are principally biodegradable, but are only degraded very slowly in the open air, wastewater, or composting plants. Known enzymes with the ability to degrade plastics could solve this problem.
Hundreds of millions of tons of polymer materials are produced globally for use in a vast and ever-growing application space with new material demands such as green chemistry polymers, consumer packaging, adhesives, automotive components, fabrics and solar cells.
Halides hold promise for improving the performance of catalysts used in carbon dioxide conversion. A team of scientists has examined the recent progress and challenges related to halides, and provided their outlook on future directions for the research.
Nanodiamond materials have great potential as catalysts. Inexpensive nanoparticles made of carbon provide very large surfaces compared to their volume. However, to catalytically accelerate chemical reactions in an aqueous medium, electrons from the catalyst need to go into solvation and in pure diamond materials this requires high-energy UV light for excitation. On the other hand, the extremely...
The first eruption in 38 years of Mauna Loa, the world's largest active volcano, is drawing visitors to Hawaii Volcanoes National Park, which is open 24 hours a day.
A climate-neutral energy supply requires a wide variety of materials for energy conversion processes, for example catalytically active materials and new electrodes for batteries. Many of these materials have nanostructures that increase their functionality. When investigating these samples, spectroscopic measurements to detect the chemical properties are ideally combined with X-ray imaging with...
Archeologists have rediscovered a pre-Hispanic fresco depicting mythological scenes in northern Peru that they had only seen in black and white photographs that were more than a century old.
Deforestation in the Brazilian Amazon destroyed an area bigger than Qatar in the 12 months through July, according to official figures released Wednesday, which showed a decline from the year before—but a sharp increase overall under outgoing President Jair Bolsonaro.
The Columbia River Gorge is a crown jewel for recreation in the Pacific Northwest, stretching more than 80 miles along the borders of Washington and Oregon and providing a wide variety of trails, campgrounds, waterfalls, and wilderness areas for recreational use. In 2017, the western portion of the area was burned by the Eagle Creek Fire, a human-caused, wind-driven blaze that ultimately burned...
A new paper sheds light on the nature of atomic nuclei. The study is published in the journal Physical Review C.
Satellite observations have revealed that weak seismic ground shaking can trigger powerful landslide acceleration—even several years after a significant earthquake.
With their lightweight nature and flexibility, thermally conductive polymer composites are applied between a heat source and a sink in electronics to dissipate the generated heat to the surroundings. Efficient heat dissipation is achieved due to the use of fillers with certain orientations that facilitate heat flow.
In recent years, many ecologists have broadened their focus from "natural" systems to an understanding of landscapes that includes social factors alongside their biophysical counterparts.
