Medical Xpress / Silent B-cell mutations may build for years before thyroid autoimmunity appears
New research suggests that autoimmune diseases may be driven by DNA mutations in immune cells that remove the natural brakes on the immune system. It reveals a previously hidden role for somatic mutations—DNA changes acquired ...
Phys.org / Cosmic dust identified as the source of Venus' enigmatic lower haze
Venus, often called Earth's twin, is in fact a planet of extremes. Beneath its thick carbon dioxide atmosphere are crushing surface temperatures and dense clouds of sulfuric acid. While the planet's main cloud layer sits ...
Phys.org / Virtual sunspots help AI find rare magnetic matches in vast solar archives
Research led by Southwest Research Institute (SwRI) has integrated three types of machine learning models to generate solar magnetic patches with physical properties and used those as a query to find matching patches in real ...
Medical Xpress / Researchers discover what may be the root cause of preeclampsia—and how to fix it
Preeclampsia is a life-threatening pregnancy complication that affects roughly 1 in 10 pregnancies worldwide and, in the United States alone, around 5%–8% of pregnancies. The condition can lead to severe, long-term health ...
Phys.org / A 'blob' in a tank is helping scientists tease out the secrets of turbulence
In a tank on the bottom floor of a University of Chicago research laboratory, scientists summon "The Blob" into existence by firing water jets to create an artfully choreographed series of rings.
Medical Xpress / Unlocking secrets of human development: How early nerve cell choices shape the peripheral nervous system
Millions of neurons branch throughout our bodies, keeping them in close communication with our brains. This peripheral network begins to take shape long before birth, as the cells of a growing embryo move into position and ...
Medical Xpress / After TBI, smoothened agonists cut swelling, inflammation, and neurological deficits
Every year in the U.S., about a million people are treated at emergency rooms for traumatic brain injuries (TBIs), and about 50,000 people die from the injuries or complicating factors, according to the International Brain ...
Phys.org / Research helps power safe return of astronauts in historic Orion splashdown
When NASA's Orion capsule splashed down in the Pacific Ocean April 10, completing a successful Artemis II mission milestone, a critical piece of the spacecraft's safe return traced back to research at Rice University.
Phys.org / Four weeks of 'safe' low-level PFAS exposure in tap water altered embryo development in mice
An Adelaide University study has revealed that per- and polyfluoroalkyl substances (PFAS) found in tap water, at levels currently considered safe, affected the development of embryos, causing irreversible damage that may ...
Phys.org / Contaminants, including ink, detected in meteorites suggest sample preparation needs improving
The IBeA group of the EHU-University of the Basque Country is proposing new measures to safeguard the purity of extraterrestrial samples. Several contaminants, including traces of ink, originating in the preparation of subsamples, ...
Phys.org / After 9,000 years of cultivation, rice has reached its thermal limit
Rice has historically been a heat-loving plant. In fact, the wild ancestor of cultivated rice once grew primarily on the sweltering, rain-swept Malay and Indochina peninsulas as well as the islands of Southeast Asia. It wasn't ...
Phys.org / Simple rules guide how proteins assemble and evolve, study finds
Researchers at Ben-Gurion University of the Negev have identified simple rules that explain how complex protein structures assemble correctly and remain functional over time, despite having many theoretically possible configurations. ...
