Phys.org / Metal deposits reveal how ice ages reshaped oxygen levels across Earth's oceans
Earth's oceans repeatedly lost oxygen and produced metal deposits during the planet's deepest ice ages. An international team of researchers analyzed manganese and other chemical signatures preserved in more than 27,000 ancient ...
Phys.org / After the Palisades and Eaton fires, research offers new answers for communities as they rebuild
More than a year after the Palisades and Eaton fires, many residents are still asking: Is my yard contaminated? What about the beach? And what should I do if there is contamination?
Medical Xpress / Skin-like test models could help improve medical devices for people of all skin tones
Many medical devices and wearable health sensors work by shining light into the skin and measuring the signal that returns. These technologies are used in products ranging from pulse oximeters to fitness trackers. However, ...
Phys.org / Why life's hardships may make conspiracy theories more appealing
People who experience greater hardship throughout their lives may become more susceptible to conspiracy theories when those experiences lead them to see the world as fundamentally unfair, according to new research.
Phys.org / Expert discusses soil fertility and tropical forest productivity
YCNCC Science Communications Fellow Samantha Tracy recently sat down with Wong to discuss the influence of soil fertility on tropical forests and their responses to global change. The study is published in the journal New ...
Phys.org / AI models atom movement to predict solid-state reaction pathways, including impurities, in minutes
A research team at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has successfully demonstrated an AI modeling approach that accurately and rapidly predicts how reactions between solid materials ...
Phys.org / Light controls nanoscale 'bubble' domains in a ferroelectric crystal
Researchers at Flinders University have discovered an unexpected way light can control tiny electronic structures inside advanced materials, a development that could help pave the way for more energy-efficient memory devices, ...
Phys.org / Incentives to sleep boost college students' grades, new study finds
A study published in the Journal of Political Economy provides the first causal evidence that improving sleep can directly enhance academic performance.
Phys.org / New findings on the eruption history of the West Eifel maar volcanoes
The West Eifel Volcanic Field comprises more than 100 maars—circular lakes formed by explosive eruptions. Until now, little was known about when these volcanic eruptions occurred. A research team from Heidelberg University, ...
Phys.org / Discarded rice husks capture toxic dyes, offering a reusable water filter
Rice is the most-eaten food on the planet, and its discarded outer husk results in some 300 billion pounds of waste per year. FIU chemistry researcher Islam Ibrahim Hussein says the inedible castoffs could be the key to cleaner ...
Tech Xplore / Composite catalyst could improve oxygen reactions in next-generation lithium-oxygen batteries
An electric vehicle that never needs recharging on a cross-country trip. Drones that fly for hours without landing. These scenarios demand energy storage far beyond what lithium-ion batteries can deliver—and lithium–oxygen ...
Phys.org / Some speed‑reading apps make big claims. But how fast can humans actually read?
Some speed-reading advocates claim that with proper training (outlined in many popular books and YouTube videos) or the use of special apps, it's possible to increase your reading rate to 1,000 words per minute or more.
