Multiple Sclerosis: Cell-Catching Implant Helps Identify Successful Treatment in Mice

University of Michigan — Tue, 18 Feb 2025 19:40:06 EST

A sponge-like implant in mice helped guide a treatment that slowed or stopped a degenerative condition similar to multiple sclerosis in humans. It also gave University of Michigan researchers a first look at how primary progressive multiple sclerosis, the fastest-progressing version of the disease, attacks the central nervous system early on.

HIV Protein Switch May Help Virus Squeeze into Host Cell Nucleus

Pittsburgh Supercomputing Center — Mon, 17 Feb 2025 15:00:00 EST

How the HIV inserts its capsid into the host cell's nuclear pore is a puzzle and a therapeutic target. Simulations on the Pittsburgh Supercomputing Center's Bridges-2 system by a University of Pittsburgh team revealed how changes in the shape of the HIV-1 capsid protein may help the capsid be more flexible.

AI Accelerates the Search for New Tuberculosis Drug Targets

University of California San Diego — Thu, 06 Feb 2025 20:25:13 EST

As one of the largest tuberculosis outbreaks in the U.S. unfolds in Kansas, UC San Diego researchers and their colleagues have published research describing the use of artificial intelligence tools to screen for new antimicrobial candidates to treat the disease.

A New Way to Detect Inflammation

Case Western Reserve University — Thu, 06 Feb 2025 19:35:44 EST

Nearly every disease has an inflammatory component, but blood tests can't pinpoint inflammation in specific organs or tissues in the human body.

InsectNet Technology Identifies Insects Around the World and Around the Farm

Iowa State University — Thu, 06 Feb 2025 09:00:44 EST

InsectNet - which is backed by a dataset of 12 million insect images, including many collected by citizen-scientists - provides identification and predictions for more than 2,500 insect species at more than 96% accuracy.

Climate Change Is Overhauling Marine Nutrient Cycles, UC Irvine Scientists Say

University of California, Irvine — Tue, 04 Feb 2025 20:45:57 EST

Computer models reveal how human-driven climate change will dramatically overhaul critical nutrient cycles in the ocean. In the Proceedings of the National Academy of Sciences, University of California, Irvine researchers report evidence that marine nutrient cycles - essential for sustaining ocean ecosystems - are changing in unexpected ways as the planet continues to warm.

New Research Reveals That Meditation Induces Changes in Deep Brain Areas Associated with Memory and Emotional Regulation

Findings provide insight about its potential as a noninvasive therapy

People Prefer Meat Alternatives if They Are Significantly Cheaper Than Real Meat, Study Shows

Martin-Luther-Universitat Halle-Wittenberg — Mon, 03 Feb 2025 04:30:46 EST

Only a few people fundamentally oppose eating plant-based meat alternatives, a recent survey of 2,100 customers in the US shows. According to the results, the price of meat alternatives is the most decisive factor for their acceptance, while similarity to meat did not matter that much.

Q&A: How Rate of CO2 Rise Can Affect a Global Ocean Current

University of Washington — Tue, 28 Jan 2025 20:30:56 EST

How fast the level of atmospheric carbon dioxide -- and with it, the temperature -- goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too.

Follow the Water: Searching for a Lunar Oasis

University of California San Diego — Sat, 25 Jan 2025 05:00:02 EST

As humankind imagines living off-planet -- on the moon, Mars and beyond -- the question of how to sustain life revolves around the physical necessities of oxygen, food and water. We know there is water on the moon, but how do we find it?
