Phys.org / Twisting atom-thin materials reveals new way to save computing energy
A recent study shows a new and potentially more energy-efficient way for information to be transmitted inside electronic systems, including computers and phones—without relying on electric currents or external magnetic fields.
Phys.org / Love hormone enters battle mode, exposing rivalry and group lines in Amazon study
The "love hormone" oxytocin (OT) plays a role not only in moments of intimacy but also in competitive situations. Researchers at the University of Zurich (UZH) have shown that OT levels increase when rivalry or clearly defined ...
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 ...
Phys.org / Portable sensor detects PFAS in water on-site, cutting need for costly lab tests
A new study has unveiled a new method to cost-effectively and practically test for "forever chemicals" in water, potentially revolutionizing environmental PFAS monitoring. Led by Griffith University, the novel PFAS detection ...
Phys.org / Genetic 'bonus material' boosts gut bacterium's oxygen tolerance up to 1,000-fold
The bacterium Segatella copri is one of the most common inhabitants of the human gut. In their latest study, researchers at the Helmholtz Centre for Infection Research (HZI) have discovered that some strains of this bacterial ...
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 / 'Indian Niño' drove record heat in 2023 and 2024, new study finds
In 2023 and 2024, Earth's average global surface temperature spiked nearly 0.3 degrees Celsius above what was already expected from climate change. Each year was declared the hottest on record and coincided with deadly wildfires, ...
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 / 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.
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 ...
Phys.org / Even the most remote ocean is contaminated with zinc from human sources, research reveals
The vast, deserted South Pacific is considered unspoiled nature. But this ocean is not as unspoiled as we would like to think. A new study by a group of researchers from ETH Zurich and the GEOMAR Helmholtz Center for Ocean ...
Phys.org / Online echo chambers can arise even without algorithmic nudges or seeking like-minded people
A new study of online communities suggests that their interaction dynamics can amplify small, local imbalances in opinions, rapidly turning initially mixed-opinion communities into highly-polarized ones—even without the algorithms ...
