To understand how driverless vehicles can navigate the complexities of the road, researchers often use game theory—mathematical models representing the way rational agents behave strategically to meet their goals.

Globally, wildfires are becoming more frequent and destructive, generating a significant amount of smoke that can be transported thousands of miles, driving the need for more accurate air pollution forecasts. A team of Penn State researchers has developed a deep learning model that provides improved predictions of air quality in wildfire-prone areas and can differentiate between wildfires and...
Houston Methodist scientists reversed infertility in sterile mice by reducing high-circulating cholesterol with a bacterial protein, showing further evidence that links high cholesterol to female infertility. This is a promising development, with one in every five women of childbearing age in the U.S. unable to get pregnant after trying for a year.
Scientists using the Relativistic Heavy Ion Collider (RHIC) to study some of the hottest matter ever created in a laboratory have published their first data showing how three distinct variations of particles called upsilons sequentially "melt," or dissociate, in the hot goo. The results, just published in Physical Review Letters, come from RHIC's STAR detector, one of two large particle tracking...
The US Environmental Protection Agency (EPA) proposed new standards on Tuesday to limit levels of harmful so-called "forever chemicals" in public drinking water.
A new demographic survey of authorship in the American Journal of Archaeology (AJA) reveals that people of color have been largely underrepresented among the scholars published in the journal.
A Wolf-Rayet star is a rare prelude to the famous final act of a massive star: the supernova. As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail. A distinctive halo of gas and dust frames the star and glows in the infrared light detected by Webb, displaying knotty structure and a history of episodic...
Scientists from the Chinese MARA-CABI Joint Laboratory for Biosafety have created a model which can estimate adult emergence periods and identify migratory populations of the yellow-spined bamboo locust from their ovarian development.
COVID is not yet under control. Despite a bevy of vaccines, monoclonal antibodies, and antivirals, the virus continues to mutate and elude us. One solution that scientists have been exploring since the early days of the pandemic may come in the form of tiny antibodies derived from llamas, which target various parts of the SARS-CoV-2 spike protein.
Almost 5 miles above sea level in the Himalayan mountains, the rocky dip between Mount Everest and its sister peak, Lhotse, lies windswept, free of snow. It is here at the South Col where hundreds of adventurers pitch their final camp each year before attempting to scale the world's tallest peak from the southeastern side.
A simple 19th-century tool is still useful to ocean scientists in the age of satellites, new research shows. The research is published in the journal Frontiers in Marine Science.
University of Minnesota students conducted crucial genome sequencing for the newly discovered soybean gall midge—a pest that is threatening the soybean crop, one of the most widely cultivated and consumed throughout the world. This small fly has been found in major soybean-producing states in the Midwest, including Minnesota, Iowa, Nebraska, South Dakota and Missouri.
The existing 3D-printed scaffolds commonly possess a thick feature size of hundreds of micrometers, which is too large for most cells (10–20 μm) to attach and proliferate for promoting tissue regeneration. Researchers from Xi'an Jiaotong University have developed a novel hybrid manufacturing technique for the fabrication of composite scaffolds with 3D-printed macroscale frameworks and aligned...
Li ion imaging by transmission electron microscopy (TEM) is the "holy grail" in the study of Li ion battery (LIB) materials. Tracking lithiation process in TEM could provide a more profound understanding of the electrode degradation mechanism during battery cycling, which accelerates material modification for better performance.
The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like blueberries in a muffin where material clusters in certain areas but may be lacking in others.
The Chinese sturgeon (Acipenser sinensis) is the largest anadromous fish in the Yangtze River and is considered a critically endangered species with only one spawning ground. Additionally, it has failed to spawn in recent years (2013, 2015, and 2017-2022), pushing the species to the brink of extinction.
Some of the most pivotal climate-change questions—and potential solutions—focus on Florida.
After verifying its potential as a pest biocontrol agent, a team at the University of Cordoba unraveled the mechanisms used by the entomopathogenic fungus Metarhizium brunneum to increase iron acquisition in melon and cucumber
There is a risk that individuals may benefit from having relatives in important posts in the public sector. This is shown in a doctoral thesis at Linköping University that investigates corruption in a mature democracy. The conclusion is that nepotism may be an underestimated problem that deserves more attention in Sweden.
The following is an interview with ESG expert professor Kim Schumacher of Kyushu University.
University students who attend interactive seminars in person get better exam results than those who do not attend, potentially equivalent to almost a full grade, new research from the University of Bath School of Management shows.
New research emphasizes how important children's well-being is for their sense of achievement.
The COVID-19 pandemic was fertile ground for conspiracy theories and misinformation on Twitter, and Bill Gates was a frequent target. A new study, which analyzes well-known conspiracy theories about the role of Bill Gates during the pandemic is published in Cyberpsychology, Behavior, and Social Networking.
A giant blob of seaweed, spanning 5,000 miles and weighing an estimated 6.1 million tons, threatens to blanket Florida beaches and Caribbean islands with smelly piles of decaying brown goop.
British scientists are tracking two enormous icebergs that broke off from Antarctica and could intrude on shipping lanes.
