Phys.org / Nation topped goal of 1 million more STEM graduates over the past decade, analysis finds
A recent analysis of national higher-education data by a researcher at the University of California, Santa Cruz, found that the United States exceeded the goal of producing one million more graduates in the fields of science, ...
Phys.org / Land degradation outpaces restoration in Africa's Great Green Wall
A new study led by Prof. Li Xiaosong from the Aerospace Information Research Institute of the Chinese Academy of Sciences has evaluated land productivity dynamics (LPD) across the African Great Green Wall (GGW) between 2013 ...
Phys.org / What should countries do with their nuclear waste? Management strategies focus on radionuclide iodine-129
One of the highest-risk components of nuclear waste is iodine-129 (I-129), which stays radioactive for millions of years and accumulates in human thyroids when ingested. In the U.S., nuclear waste containing I-129 is scheduled ...
Phys.org / Ancient trees' inefficient photorespiration may have helped stabilize Earth's atmosphere during last ice age
Ancient trees may have played a key role in regulating Earth's climate during the last ice age—by 'breathing' less efficiently.
Phys.org / New modeling shows difficult future for the Great Barrier Reef under climate change
The most sophisticated modeling to date forecasts that, under the current global emissions pathway, the Great Barrier Reef could lose most of its coral by the end of the century, but curbing climate change and strategic management ...
Phys.org / SPRTA: A smarter way to measure evolution uncertainty
When COVID-19 arrived, researchers tried to build evolutionary family trees—known as phylogenetic trees—of the virus. These help scientists understand when new virus strains appear and how they are linked to each other. ...
Phys.org / Polar ocean turbulence projected to intensify as sea ice declines
A study published in Nature Climate Change by an international team of scientists from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea, presents new evidence that ocean turbulence and ...
Phys.org / How hops produce chiral α-bitter acids that give beer its signature taste
Hops are an essential ingredient in beer brewing and an important economic crop. The female flowers of hops are covered in tiny glandular trichomes that synthesize and store a variety of specialized metabolites, collectively ...
Phys.org / First complete 3D structure of yellow fever virus reveals key differences between strains
University of Queensland researchers have captured the first high-resolution images of the yellow fever virus (YFV), a potentially deadly viral disease transmitted by mosquitoes that affects the liver. The research was published ...
Phys.org / Tying climate action to protecting a way of life can increase motivation, study says
People need to feel that climate change is affecting them now or that taking action is a patriotic act for their country to overcome apathy toward environmental efforts, a new global study has found.
Phys.org / Microcompartment approach expands possibilities for studying viruses in the environment
A new method vastly improves on the existing approach for single-cell genetic sequencing, enabling scientists to read the genomes of individual cells and viral particles in the environment more quickly, efficiently, and cost-effectively.
Phys.org / Astronomers may have found the first stars that formed after the Big Bang
For years, astronomers have been on the hunt for the first generation of stars, primordial relics of the early universe. And now they may have just found them. Ari Visbal from the University of Toledo, Ohio and colleagues ...
