Food and non-alcoholic drink products in Mexico were substantially reformulated to be healthier following the 2020 introduction of warning labels identifying products with excessive content of calorie

A major review of over 67,000 animal species has found that while the natural world continues to face a biodiversity crisis, targeted conservation efforts are helping bring many species back from the brink of extinction. The study draws on data from the IUCN Red List, the world’s largest database of species conservation status. The researchers say their results, reported in the journal PLOS Biology, highlight both the successes and the need for urgent action. The world is facing a global biodiversity crisis, with 28% of more than 160,000 assessed species threatened with extinction, and an estimated one million species facing this fate due to human activities. ...

Targeted conservation actions are essential to prevent wildlife extinctions, but more efforts are needed to fully recover biodiversity, according to a study published March 18th in the open-access journal PLOS Biology by Ashley Simkins of the University of Cambridge, UK and colleagues. Out of over 166,000 species assessed by the International Union for Conservation of Nature, around 28% are threatened with extinction. Global efforts to prevent extinction and recover biodiversity have had some success, but there is limited data to show which conservation actions are most effective. In this study, Simkins and colleagues compile information ...

WASHINGTON —The Journal of the Society for Cardiovascular Angiography & Interventions (JSCAI) proudly announces the publication of a groundbreaking special issue: The Role of Artificial Intelligence in Cardiovascular Interventions.   This issue explores how artificial intelligence (AI) is revolutionizing interventional cardiology, from diagnostic precision to procedural planning and patient outcomes. It features a collection of original research, reviews, and viewpoints that delve into AI’s applications across ...

DETROIT — A grant to Wayne State University from the National Science Foundation (NSF) is opening new doors for researchers and students to explore the future of autonomous vehicles, machines and drones. Zheng Dong, Ph.D., assistant professor of computer science in Wayne State’s School of Engineering, was awarded a five-year, $595,611 NSF grant for the project, "CAREER: ChronosDrive: Ensuring Timing Correctness in DNN-Driven Autonomous Vehicles with Accelerator-Enhanced Real-Time SoC Integration." “We ...

When Jeff Kneebone was a college student in 2002, his research involved a marine mystery that has stumped curious scientists for the last two decades. That mystery had to do with thorny skates in the North Atlantic. In some parts of their range, individuals of this species come in two distinct sizes, irrespective of sex, and no one could figure out why. At the time, neither could Kneebone. In a new study, Kneebone and researchers from the Florida Museum of Natural History say they’ve finally found an answer. And it’s all thanks to COVID-19. People have known about the size discrepancy in thorny skates for nearly a century, but it became critically ...

It is a deep question, from deep in our history: When did human language as we know it emerge? A new survey of genomic evidence suggests our unique language capacity was present at least 135,000 years ago. Subsequently, language might have entered social use 100,000 years ago. Our species, Homo sapiens, is about 230,000 years old. Estimates of when language originated vary widely, based on different forms of evidence, from fossils to cultural artifacts. The authors of the new analysis took a different approach. ...

March 18, 2025, Mountain View, CA -- Where do meteorites of different type come from? In a review paper in the journal Meteoritics & Planetary Science, published online this week, astronomers trace the impact orbit of observed meteorite falls to several previously unidentified source regions in the asteroid belt.  “This has been a decade-long detective story, with each recorded meteorite fall providing a new clue,” said meteor astronomer and lead author Peter Jenniskens of the SETI Institute and NASA Ames Research Center. “We now have the first outlines of a geologic map of the asteroid belt.”  Ten years ago, ...

A new large-scale study co-led by UCLA Health Jonsson Comprehensive Cancer Center investigators provides the strongest evidence yet that a shorter, standard-dose course radiation treatment is just as effective as conventional radiotherapy for prostate cancer, without compromising the safety of patients. The shorter approach, known as isodose moderately hypofractionated radiotherapy (MHFRT), delivers slightly higher doses of radiation per session, allowing the total treatment duration to be over four to five weeks instead of seven to eight weeks. According to the study, patients who received this type ...

There’s a major difference between humans and current artificial intelligence (AI) capabilities: common sense. According to a new visionary paper by Walid Saad, professor in the College of Engineering and the Next-G Wireless Lead at the Virginia Tech Innovation Campus, a true revolution in wireless technologies is only possible through endowing the system with the next generation of AI that can think, imagine, and plan akin to humans. Published in the Proceedings of the IEEE Journal's Special Issue on the Road to 6G with Ph.D. student Omar Hashash and postdoctoral associate Christo Thomas, the paper's findings suggest: The missing link in the wireless revolution is ...

URBANA, Ill. – Livestock agriculture is bearing the cost of extreme weather events. A new study from the University of Illinois Urbana-Champaign explores how heat stress affects U.S. dairy production, finding that high heat and humidity lead to a 1% decline in annual milk yield. Small farms are hit harder than large farms, which may be able to mitigate some of the effects through management strategies. “Cows are mammals like us, and they experience heat stress just like we do. When cows are exposed to extreme heat, it can have a range of negative physical effects. There is an increased risk of infection, restlessness, and decreased ...
