Phys.org / Fossil fish sheds new light on extra teeth evolution to devour prey
Experts have uncovered the earliest known example of a fish with extra teeth deep inside its mouth—a 310-million-year-old fossilized ray-finned fish that evolved a unique way of devouring prey.
Phys.org / Despite cloudy skies, bees can still use sun for navigation
The hunt for nectar can take honeybees kilometers away from their hive into unknown territory—and yet, they always find their way back. The sun's position in the sky serves as a kind of compass for bees, even when clouds ...
Phys.org / Climate change is making rollercoaster harvests the new normal
A new global study led by the University of British Columbia shows that hotter and drier conditions are making food production more volatile, with crop yields swinging more sharply from year to year. For some, it may mean ...
Phys.org / Hidden step in hemoglobin's carbon monoxide release challenges long-held assumption
Researchers have made a groundbreaking discovery about hemoglobin, the protein responsible for carrying oxygen throughout the body. The findings challenge decades of scientific assumptions and provide new insights into fundamental ...
Phys.org / Standardized approach replicates microplastics in the lab with greater precision
McGill University researchers have developed a novel method to replicate four types of microplastics commonly found in the environment, providing researchers with a standardized approach to study their toxic effects.
Phys.org / Countries' carbon budget math is broken—study finds bias in calculations
Climate action is falling behind on the goals as stated in the Paris Agreement. To meet those goals, countries must act according to their "fair share" targets. However, researchers from Utrecht University found a bias in ...
Phys.org / Plant-based dog foods not nutritionally complete, but may suffice with supplements, study suggests
In a study of dog foods sold in the U.K., plant-based foods did not fully meet nutritional guidelines—but meat-based and veterinary foods also fell short of being nutritionally complete. Rebecca Brociek of the University ...
Phys.org / Explainable AI supports improved nickel catalyst design for converting carbon dioxide into methane
The conversion of carbon dioxide into clean fuels is regarded as an important route toward carbon neutrality. CO2 methanation, in particular, has drawn increasing interest due to its favorable thermodynamic properties and ...
Phys.org / High-throughput phenotyping platform uncovers genetic basis of wheat spike morphology evolution
A collaborative research team led by Lu Fei from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences (CAS) and Guo Zifeng from the Institute of Botany of CAS, together with their ...
Phys.org / Roll-to-roll method streamlines DNA sequencing with faster, more efficient fluidics
Researchers at Beijing Genomics and IMDEA Nanociencia institutes have introduced a novel method that could significantly accelerate efficiency and reduce the cost of handling fluidics in DNA sequencing.
Phys.org / Sensors reveal surprising drop in methane emissions after flooding in coastal wetlands
University of Toledo environmental researchers trooped through the woods and wetlands of the Ottawa National Wildlife Refuge for a week in early June. Their mission? To outfit an approximately 16-acre site with nearly 300 ...
Phys.org / A 'wasteful' plant process makes a key prenatal vitamin—climate change may reduce it
New research from Michigan State University reveals that photorespiration—long considered a wasteful process—is essential for producing a crucial nutrient for preventing birth defects.
