Medical Xpress / Sleep medication linked to safer outcomes than antipsychotics for older adults with delirium
A large U.S. study suggests that older adults hospitalized with delirium may experience better outcomes when treated with trazodone, commonly used to treat depression and sleep problems, rather than commonly used antipsychotic ...
Medical Xpress / Study maps 30 rheumatoid arthritis biopsies, linking joint scarring to treatment resistance
Rheumatoid arthritis (RA) is a common autoimmune disease where the body's immune system mistakenly attacks the lining of its own joints, causing chronic pain, swelling, and stiffness. While there have been remarkable advancements ...
Phys.org / Spider spinneret evolution: How a genome duplication event 438 million years ago set the stage
Scientists have uncovered a 400-million-year-old genetic secret that gave spiders the ability to produce silk and weave their webs. Spiders didn't begin their journey on Earth in the same way as they are known today. Arthropods ...
Phys.org / A more realistic picture of platinum electrodes
Current electrochemical theory does not adequately describe realistic platinum electrodes. Scientists at Leiden University have now, for the first time, mapped the influence of imperfect platinum surfaces. This provides a ...
Phys.org / Global plastics treaty negotiations: Success is still possible, researchers argue
Plastic pollution is causing severe problems worldwide. However, negotiations at the United Nations in Geneva last August did not result in the expected global plastics treaty. On 7 February 2026, the Intergovernmental Negotiating ...
Phys.org / As Rubin's survey gets underway, simulations suggest it could find about six lunar-origin asteroids per year
Most near-Earth asteroids are thought to drift in from the main asteroid belt. But a small subset may have a much closer origin: the moon. One intriguing example is 469219 Kamoʻoalewa (2016 HO3), an Earth quasi-satellite ...
Tech Xplore / A smelly snapshot of the current state of electronic noses for robots
Robots are getting better at sniffing out smells thanks to improvements in electronic noses (e-noses). A comprehensive review of the state of robot olfaction, published in the journal npj Robotics, has surveyed recent advances ...
Phys.org / Two-step approach creates more sustainable protein nanostructures for advanced sensing and therapeutics
Gas vesicles are among the largest known protein nanostructures produced and assembled inside microbial cells. These hollow, air-filled cylindrical nanostructures found in certain aquatic microbes have drawn increasing interest ...
Phys.org / Air pollution causes social instability in ant colonies, triggering attacks on returning nest mates
A research team from the Max Planck Institute for Chemical Ecology has shown in a new study that ants returning from habitats affected by air pollution are attacked when they re-enter the colony. The cause: air pollution, ...
Phys.org / Study finds long-term research partnerships can strengthen sustainable urban farming
In South and West Dallas, initiatives like Restorative Farms have turned vacant lots into hubs for fresh produce, job training, and sustainable practices such as hydroponics—helping combat food deserts and build local food ...
Phys.org / Resilience bonds could serve as an insurance solution to address climate change risks
Researchers with Lehigh University's Center for Catastrophe Modeling and Resilience, led by anthropologist David G. Casagrande, have identified two urgent challenges the United States faces in adapting to climate change: ...
Phys.org / How bacteria learned to target numerous cell types
Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that drives constant evolution. ...
