Poor mental health, rising obesity rates, exposure to violence and climate change are among the key challenges facing our adolescents today, according to a global report.
On the origin (and fate) of plants that never bloom
Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. The research not only adds a facet to possible evolutionary strategies, but also lends weight to Darwin's suspicion that this strategy might be a path to extinction.
Common diabetes drug helps chickens lay more eggs
What do chickens and people with a common reproductive disorder have in common? More than one might think -- and a widely-used diabetes medication might just be the surprising link.
How to solve a bottleneck for CO2 capture and conversion
New research could improve the efficiency of electrochemical carbon-dioxide capture and release by six times and cut costs by at least 20 percent. Researchers added nanoscale filtering membranes to a carbon-capture system, separating the ions that carry out the capture and release steps, and enabling both steps to proceed more...
Wild spinach offers path to breed disease resistance into cultivated varieties
Several varieties of wild spinach that originated in Central Asia show resistance to a destructive soil-borne pathogen that beleaguers growers of spinach seed in the Pacific Northwest -- a finding that can be used to breed hardier crops.
Advanced genomics study improves detection of hard-to-find diarrheal infections
A study has used advanced genetic and genomic techniques to offer a major step forward in understanding and diagnosing infectious intestinal diseases. The large-scale study analyzed more than 1,000 stool samples from people with diarrheal illness to harness two cutting edge tools. The study used metagenomic (DNA-based) and metatranscriptomic (gene...
Molecules in blood and urine could reveal how much ultra-processed food you eat
Sets of metabolites found in blood and urine reliably correspond with how much energy from ultra-processed food a person consumes, according to a new study.
Thousands of Animal Species Threatened by Climate Change, Novel Analysis Finds
A novel analysis suggests more than 3,500 animal species are threatened by climate change and also sheds light on huge gaps in fully understanding the risk to the animal kingdom.
New Chip Uses AI to Shrink Large Language Models’ Energy Footprint by 50%
Oregon State University College of Engineering researchers have developed a more efficient chip as an antidote to the vast amounts of electricity consumed by large-language-model artificial intelligence applications like Gemini and GPT-4.
First-of-its-Kind Global Study Shows Grasslands can Withstand Climate Extremes with a Boost of Nutrients
Fertilizer might be stronger than we thought.
