Phys.org / Smart hydrogels act as 'micromachines' to squeeze and study living cells
Within tissues, cells are embedded in complex, three-dimensional structures known as the extracellular matrix. Their biomechanical interactions play a crucial role in numerous biological processes. Scientists at the Max Planck ...
Phys.org / Flood risks in delta cities are increasing, Shanghai study finds
New research shows how the combination of extreme climate events, sea-level rise and land subsidence could create larger and deeper floods in coastal cities in future.
Medical Xpress / GLP-1RAs shown to reduce risk of cardiovascular death
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) such as semaglutide, liraglutide, and tirzepatide are widely prescribed both for Type 2 diabetes and weight loss. These drugs also have shown promise in clinical trials ...
Phys.org / Southern Annular Mode in most positive state in 1,000 years, review finds
A new review has revealed that the Southern Annular Mode (SAM), the Southern Hemisphere's most influential climate driver, is now in its most positive state in more than 1,000 years. If greenhouse gas emissions continue to ...
Phys.org / Bird-of-paradise inspires darkest fabric ever made
The color "ultrablack"—defined as reflecting less than 0.5% of the light that hits it—has a variety of uses, including in cameras, solar panels and telescopes, but it's difficult to produce and can appear less black when ...
Medical Xpress / Supplement trio shows promise in reversing autism-linked behaviors in mice
Researchers led by Tzyy-Nan Huang and Ming-Hui Lin from Academia Sinica in Taiwan report that a low-dose mixture of zinc, serine, and branch-chain amino acids can alleviate behavioral deficits in three different mouse models ...
Medical Xpress / Pain med side effects may be masquerading as heart failure
Clinicians may fail to recognize common side effects of drugs like gabapentin—which are frequently prescribed for nerve pain—leading them to prescribe unnecessary medications that cause yet more side effects. This phenomenon, ...
Phys.org / Elephant seals recognize their rivals from years prior, study finds
Humans are not the only animals that can remember the voices of their old acquaintances. Elephant seals, too, can remember the calls of their rivals even a year later.
Tech Xplore / LLMs choose friends and colleagues like people, researchers find
When large language models (LLMs) make decisions about networking and friendship, the models tend to act like people, across both synthetic simulations and real-world network contexts.
Phys.org / Urban sprawl could deny 220 million people access to clean water by 2050
A new study analyzing more than 100 cities across Asia, Africa, and Latin America has quantified the stark consequences of urban sprawl on water and sanitation access, finding that how cities grow might determine whether ...
Phys.org / First fertilizer: A chemical process that may have sparked life on Earth
University of Alberta geochemists have discovered a missing piece to one of the great mysteries of science—the origin of life on Earth.
Phys.org / Light-triggered nanoscale heating can control communication between nerve cells
Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report the successful creation of artificial synaptic vesicles that can be remotely controlled by near-infrared (NIR) light. By embedding ...
