Medical Xpress / Semaglutide may increase risk for nonarteritic anterior ischemic optic neuropathy
People with type 2 diabetes starting semaglutide have more than a doubled risk for nonarteritic anterior ischemic optic neuropathy (NAION) versus those starting sodium-glucose cotransporter-2 inhibitors (SGLT2is), according ...
Phys.org / Image: Curiosity rover surveys boxwork region of Mars
NASA's Curiosity Mars rover captured this panorama of boxwork formations—the low ridges seen here with hollows in between them—using its Mastcam on Sept. 26, 2025, the 4,671st Martian day (sol) of the mission. These boxwork ...
Phys.org / Hair-width LEDs could eventually replace lasers
LEDs no wider than a human hair could soon take on work traditionally handled by lasers, from moving data inside server racks to powering next-generation displays. New research co-authored by UC Santa Barbara doctoral student ...
Phys.org / Jupiter's Galilean moons may have gained life's building blocks at birth
Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter's Galilean moons during their ...
Phys.org / Tuning in to fluorescence to farm smarter: Monitoring plant light use saves indoor farm energy costs
Plant owners with a so-called green thumb often seem to have a more finely tuned sense of what their plants need than the rest of us. A new "smart lighting" system for indoor vertical farms grants this ability on a facility-wide ...
Phys.org / A new form of aluminum unlocks sustainable and cheaper catalysts
A research team at King's College London has isolated a new form of aluminum—a highly abundant metal, that could provide a far cheaper and more sustainable alternative to commonly used rare earth metals. Dr. Clare Bakewell, ...
Medical Xpress / New 'liver-on-a-chip' device could make drug safety testing more reliable
Creating a drug that might help treat or cure a health condition in humans is a long, complex process. After developing a candidate drug that shows potential—a process that, in and of itself, can take decades—scientists ...
Phys.org / 40,000-year-old Stone Age symbols may have paved the way for writing, long before Mesopotamia
Over 40,000 years ago, our early ancestors were already carving signs into tools and sculptures. According to a new analysis by linguist Christian Bentz at Saarland University and archaeologist Ewa Dutkiewicz at the Museum ...
Medical Xpress / Rare genetic variant protects against malaria-causing parasite by making red blood cells bigger
Scientists have found that a special component in some people's blood provides them with natural protection against malaria. A recent study has demonstrated that a genetic variant named rs112233623-T reduces the activity ...
Phys.org / Alloy-engineered valleytronics: Microscopic mechanism gives scientists precise control over how excitons behave
Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up tangible prospects for technological ...
Phys.org / System isolates single extracellular vesicle surface proteins to map function
Extracellular vesicles (EVs) are tiny biological bubbles that carry nucleic acids and proteins between cells, playing an essential role in tissue repair, neuroprotection and immune health. By isolating the surface proteins ...
Phys.org / Early-life challenges and experiences shape how boldly bats behave as adults
What makes one bat take risks and venture far from its roost in search of food, while another stays close to familiar, safer areas? A new study from Tel Aviv University's School of Zoology reveals that the environment in ...
