Phys.org / A familiar magnet gets stranger: Why cobalt's topological states could matter for spintronics
The element cobalt is considered a typical ferromagnet with no further secrets. However, an international team led by HZB researcher Dr. Jaime Sánchez-Barriga has now uncovered complex topological features in its electronic ...
Phys.org / Ambitious climate action could save 1.32 million lives a year by 2040
Ambitious climate action to improve global air quality could save up to 1.32 million lives per year by 2040, according to a new study. The research, led by Cardiff University, shows how developing countries rely heavily on ...
Medical Xpress / Common anti-seizure drug prevents Alzheimer's plaques from forming, study shows
While physicians and scientists have long known that Alzheimer's disease involves the buildup of toxic protein fragments in the brain, they have struggled to understand how these harmful fragments are produced. Now, in a ...
Phys.org / Exploring how the Gulf Stream affects the climate system and the carbon cycle
It is well documented that the Gulf Stream plays a pivotal role in the climate system through its transfer of heat, which ultimately supplies warmth to northern latitudes in the North Atlantic. What remains less well understood ...
Phys.org / Underestimated wake: Shipping traffic causes more turmoil in the Baltic Sea than expected
Commercial shipping not only affects the Baltic Sea on the surface, but also has a significant impact on the water column and the seabed. A study by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) and Kiel ...
Phys.org / Sunlight extracts oxygen from regolith using solar chemistry
NASA's Carbothermal Reduction Demonstration (CaRD) project has completed an important step toward using local resources to support human exploration on the moon. The CaRD team performed integrated prototype testing that used ...
Phys.org / 7,000 years of change: How humans reshaped Caribbean coral reef food chains
Human activity has lessened the resilience of modern coral reefs by restricting the food-fueled energy flow that moves through the food chains of these critical ecosystems, reports an international team of researchers in ...
Tech Xplore / Solar-powered seesaw extractor simultaneously extracts lithium and desalinates water
The global demand for lithium has skyrocketed over the last several years due to the rapid growth of the electric vehicle market and grid-storage solutions. Currently, production capacity is limited and unlikely to meet future ...
Phys.org / A DNA 'on-off' switch? Light and redox cues reversibly link strands for nanotech
DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this information-storage function ...
Phys.org / How plants balance woody xylem and fleshy tissues: Thermospermine targets methylated ribosomes
Scientists have identified a crucial mechanism that allows plants to shape their vascular systems, determining whether they grow soft edible storage organs or develop the rigid woody tissue characteristic of trees. Published ...
Phys.org / How AI is distorting online research, from polls to public policy
Artificial intelligence is increasingly able to simulate human behavior and answer online surveys and political polls, putting the reliability of survey-based research at risk. Consequences can be serious, not only for science ...
Medical Xpress / A glaucoma drug may help prevent opioid relapse
An existing drug currently used to treat glaucoma, altitude sickness, and seizures may also have the potential to prevent relapse in opioid use disorder, according to a study by researchers at University of Iowa Health Care. ...
