Phys.org / Space junk falls to Earth faster when sunspots peak, reshaping satellite collision forecasts
Solar emissions exert 'drag' on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the sun's activity across ...
Phys.org / Aircraft measurements reveal surprisingly strong Southern Ocean biological productivity
The biological productivity of the Southern Ocean in the summertime is substantially greater than many previous estimates have suggested, according to new airborne research by the U.S. National Science Foundation National ...
Phys.org / AI matches human teachers: Brief pre-lecture chat boosts students' brain synchrony and learning outcomes
Millions of students worldwide have long relied on self-paced learning through pre-recorded video lectures, a model that forms the backbone of massive open online courses (MOOCs) and large-scale online education. Since the ...
Medical Xpress / Lithium not working? Large-scale study highlights favorable treatment strategies for bipolar disorder
Bipolar disorder is a mental health condition estimated to affect between 1% and 3% of people worldwide. Its main symptoms include extreme mood swings, ranging from periods of high activity and emotional high (i.e., mania) ...
Phys.org / Cool beans, smart roots: Special cell helps seedlings survive drought battered and nutrient poor soils
Researchers have identified a previously unknown cell type hidden on the roots of common beans, a microscopic survival mechanism that could inform the development of more climate-resilient crops and reduce fertilizer dependence.
Tech Xplore / Water-splitting catalyst unlocks cheaper hydrogen at significantly lower temperatures
University of Birmingham research published today has shown a new low-temperature method for producing hydrogen that is suitable for both centralized hydrogen production, and also local generation using waste heat from large-scale ...
Medical Xpress / Direct-to-proteasome strategy degrades two cancer proteins and may curb drug resistance
A preclinical study has developed a strategy that enables the forced elimination of proteins that help tumors survive chemotherapy. This finding opens a new avenue to tackle resistance to cancer treatments, one of the major ...
Phys.org / How higher temperatures can benefit (or devastate) bumble bee populations
New research finds that higher temperatures can actually benefit some bumble bee species—particularly those that make subterranean nests. However, periods of extreme heat appear to offset those benefits, and may contribute ...
Phys.org / Cold-triggered ion channel in bacteria may point to broader temperature-sensing mechanism
All lifeforms need to continuously adapt to temperature changes to survive. Now, Weill Cornell Medicine investigators studying a bacterial protein have identified a new mechanism of sensing cold temperatures. The finding ...
Science X / An ancient quantum machine controls our immune system—and researchers just discovered how it works
Our immune system is much older than we think. Long before dinosaurs existed, early life forms had developed a powerful defense system. Innate immunity has existed since the Cambrian period—that is, since the time when almost ...
Science X / Huge tsunami in popular area for Alaskan cruises provides lessons in steep, mountainous terrain
When part of a mountain in southeast Alaska slid into the ocean last summer, it triggered the second highest tsunami ever recorded. That tsunami ran 481 meters—one-and-a-half times the height of the Eiffel Tower—up the wall ...
Phys.org / Why some Europeans face deadlier heat and cold: Inequality map reveals who is most at risk
Regions with greater socioeconomic inequalities are more affected by cold weather, whereas areas with higher levels of wealth and urbanization are at greater risk during heat waves and lower risk during cold spells. This ...
