– The Amazon forest is changing rapidly as a result of human activities, including deforestation for agriculture, such as these soybean fields in Belterra, Pará, Brazil. Remaining areas of forest are experiencing an increased incidence of fires, drought, and the effects of neighboring land uses. These changes threaten local biodiversity and communities and alter the global climate. Science Magazine (January 27, 2023)

It’s unacceptable that millions living in poverty still lack access to safe water and basic sanitation.
Nature Water will help researchers to find a way forward.
Repeating bursts of X-rays lead scientists to a black hole that eats in spurts.
At least four articles credit the AI tool as a co-author, as publishers scramble to regulate its use.
“Even more importantly, we’ve shown you can collect the blood drop at home and mail it into the lab,” said Michael Snyder, PhD, director of the Center for Genomics and Personalized Medicine and senior author on the research, which was published in Nature Biomedical Engineering on Jan. 19.
– Researchers at Stanford Medicine (January 19, 2023) Stanford Medicine have shown they can measure thousands of molecules — some of which are signals of health — from a single drop of blood.
Unlike finger-prick testing for diabetes, which measures a single type of molecule (glucose), multi-omics microsampling gives data about thousands of different molecules at once.
A single drop of blood can yield measurements for thousands of proteins, fats and other biomarkers, researchers at Stanford Medicine found.
The new approach combines a microsampling device — a tool used to self-administer a finger prick — with
“multi-omics” technologies, which simultaneously analyze a vast array of proteins, fats, by-products of metabolism and inflammatory markers.
