Phys.org / Fire provides long-lasting benefits to bird populations in Sierra Nevada National Parks
Researchers have found that low to moderate-severity fires not only benefit many bird species in the Sierra Nevada, but these benefits may persist for decades. In addition to a handful of bird species already known to be ...
Phys.org / Wheat varieties bred for top yields in good conditions also excel in tough environments
José Luis Araus, professor at the University of Barcelona's Faculty of Biology and member of Agrotecnio—CERCA center in agrotechnology—participated in a study showing that wheat varieties that perform best under ideal ...
Phys.org / Frozen clues: Mars' crater deposits reveal a history of shrinking ice volumes through ages
For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into the dry planet we see today. A new study published online on September 2, 2025, in the Geology journal, ...
Phys.org / Analysis finds gaps in forest carbon offset projects, with most overstating climate impacts
Most Reducing Emissions from Deforestation and forest Degradation (REDD+) forest carbon offset projects significantly overstate their climate benefits, according to a new study published in Science.
Phys.org / Fossil fuel companies control a mere 1.42% of renewable energy projects worldwide, study reveals
The fossil fuel industry is falling far short of its pledge to lead the energy transition, according to new research from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB). ...
Phys.org / Parched soils can spark hot drought a nation away
Dry soils in northern Mexico may trigger episodes of simultaneous drought and heat wave hundreds of miles away in the southwestern United States, such as Arizona, New Mexico, and Texas, according to a new study. These "hot ...
Phys.org / Nanoscale X-ray imaging reveals bulk altermagnetism in MnTe
Magnetic materials have been known since ancient times and play an important role in modern society, where the net magnetic order offers routes to energy harvesting and data processing. It is the net magnetic moment of ferromagnets ...
Phys.org / These songbirds learn more from siblings than from parents
Siblings are special. Whether a sibling serves as protector or tormentor, friend or foe, the relationship between siblings is like no other. They witness each other's childhoods—sharing parents, history, secrets and advice.
Phys.org / Climate change may increase the spread of neurotoxin in the oceans
Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury. That is shown in a new study published in Nature Water, ...
Phys.org / Ultra-sensitive light-based sensor developed for handheld Alzheimer's blood test
Researchers have made a significant advance in the development of a blood test for Alzheimer's, creating a new sensor design that is ultra-sensitive, outperforms competing technologies and can be built into a handheld device.
Phys.org / Programmable proteins use logic to improve targeted drug delivery
Targeted drug delivery is a powerful and promising area of medicine. Therapies that pinpoint the exact areas of the body where they're needed—and nowhere they're not—can reduce the medicine dosage and avoid potentially ...
Phys.org / More people believe in conspiracy theories than you might think
Put on your tinfoil hats: New research finds that belief in conspiracy theories might be more common in the U.S. than you might think.
