Phys.org / Why ancient grasslands, once plowed, don't grow back the same
When a 10,000-year-old prairie is plowed up to plant corn or a savanna is consumed by a strip mall, these once-grassy expanses, if left to regrow, can eventually look vaguely like they did before. But a growing body of research ...
Phys.org / Simulations reveal asymmetric diffusion of magnetic skyrmions through an off-center gate
Diffusion is a fundamental natural phenomenon that can be observed across a wide range of length and time scales. It plays a key role in many fields, including physics, biology and economics. In particular, asymmetric or ...
Medical Xpress / AI and proteomics uncover seven blood proteins linked to vasculitis remission
Vasculitis is a disease in which the immune system mistakenly attacks blood vessel walls, causing them to become inflamed. If left untreated, the rare disease can severely damage organs, including the kidneys and lungs. Physicians ...
Medical Xpress / Our obsession with 'maxxing' every aspect of our lives could actually be stressing us out
If you want to improve yourself, your health or your lifestyle, you need to do it to the "maxx"—according to social media, at least.
Phys.org / Scientists resurrect ancient proteins, offering new antibiotic leads
University of Oregon biologists have resurrected prehistoric proteins up to 160 million years old that carry natural antimicrobial properties. The revived molecules could inspire the design of new treatments for antibiotic-resistant ...
Tech Xplore / Bill Gates warns world unprepared for AI upheaval
Bill Gates warned Wednesday that the world is dangerously unprepared for the upheaval brought by artificial intelligence, with the technology destroying jobs and threatening human connection, especially for young people.
Medical Xpress / We can't quit smartphones, but we can manage digital junk food better
Amy, a 27-year-old software developer, has struggled with disordered eating since she was a teenager. "But after learning to code, I got much better," she said in a research interview. "I often code for 10 or more hours without ...
Phys.org / Plant-like chemical gardens show how simple reactions build complex structures
The famous quote by Cicero, "If you have a garden and a library, you have everything you need," reminds us that the beauty of life lies in the harmony between nature and knowledge. More than 2,000 years later, this idea still ...
Phys.org / Even protected Florida wetlands can't escape microplastic pollution
Microplastics are turning up almost everywhere—from oceans and rivers to soils and sediments—yet far less is known about what happens when they enter freshwater wetlands. Often overlooked in favor of marine and coastal environments, ...
Tech Xplore / Major security weaknesses found in leading open-weight LLMs
Safety protections built into some of the world's most widely used artificial intelligence (AI) models can be stripped away with alarming ease, according to a new international study.
Phys.org / Researchers develop hydrogels to create a programmable niche for blood stem cells
A research team from Tel Aviv University and the Leibniz Institute of Polymer Research Dresden (IPF), led by Ayala Lampel and Carsten Werner, has developed a peptide-glycosaminoglycan hydrogel system that creates a programmable ...
Phys.org / Vacuum-fluctuation-enhanced superconductivity demonstrated for the first time
In a study published in Nature on Aug. 19, a research team has enhanced superconductivity through vacuum fluctuations for the first time. The achievement marks a significant advance in controlling quantum states of matter.
