Scientists discovered that tiny fragments from mouse mitochondria can make the body’s defense cells work against tumors. These fragments, called formyl peptides, are normally produced when bacteria or mitochondria break down proteins. Researchers first identified five specific mouse peptides t
Scientists from Seoul National University are using tiny tags on Weddell seals to learn how a warming ocean is changing life beneath Antarctica’s ice. They first capture the seals on sea‑ice near Thwaites Glacier by carefully approaching from behind and gently darting a sedative into the animal’s
Scientists are looking for ways to store energy quickly and safely. One idea is to use tiny hydrogen ions, called protons, as the moving charge in batteries. Protons can move fast through solid materials, which could let a battery charge and discharge almost instantly. The big problem is that not m
Schools in San Francisco were closed on Monday when teachers walked off the job for the first time since 1979. The strike was sparked by demands for better health care and higher pay. About 50, 000 students were affected because parents had to find new child‑care and meals. Union leaders an
Scientists are looking at why people with a muscle‑inflammation disease called idiopathic inflammatory myopathy (IIM) often develop heart failure. They used computer tools to sift through many genes and found a handful that might be linked to the heart problems. One of these is a small RNA called mi
Schools are always looking for ways to make learning more effective. One idea that has been gaining traction is physically active learning. This means getting students to move around while they learn. But there are some problems with this approach. For one, it's often seen as just a way to keep kids
Scientists have created four new compounds that could be game-changers in the fight against autoimmune diseases and severe infections. These compounds, named IGYZT01046, IGYZT01058, IGYZT01066, and IGYZT01068, were designed to target a key protein called IRAK-4, which plays a big role in these condi
Science has a big problem. A place called arXiv helps scientists share their work quickly. It's like a big online noticeboard where researchers post their findings before they get officially checked. This has been super useful for a long time. But now, AI is causing trouble. AI can make fake scienc
Schools are quickly adopting AI-powered tools to help teach students. These tools can gather personal info like voices, images, and handwriting. In early 2025, Worcester Public Schools tested a literacy app that recorded student voices to improve its AI model. Parents were not told about this test o
Scientists have found that a substance called l-malic acid (l-MA) can help a good gut bacteria, Bifidobacterium breve Bb18 (Bb18), survive better in harsh conditions. This could be a big deal for people with gut inflammation. In lab tests, they discovered that adding 0. 4% l-MA made Bb18 much stron
