Medical Xpress / Immune cells in human lung tissue may drive the development of autoimmune disease
A massive analysis of immune cells in human tissue is yielding clues to the root causes of lung and autoimmune diseases.
Medical Xpress / Bacterial supplements may boost female fertility
As women get older, their uterine environment changes. This includes a decrease in a beneficial bacterium called Lactobacillus gasseri, which may make conception—whether natural or via in vitro fertilization—difficult. In ...
Medical Xpress / Map of tonsil's genetic 'spaghetti' yields insights into immunity
About 2 meters (6.6 feet) of genetic material must fit into the nucleus of each of most of our trillions of cells, coiling and winding to form what looks like a tangled mess. But when genes are used, how they are used and ...
Phys.org / Long-term study suggests landfill methane emissions are far higher than estimates
Methane is an especially potent greenhouse gas, causing much more warming than carbon dioxide on a unit-for-unit basis—and a new, uniquely long-term study of emissions at a New Jersey landfill suggests that estimates of methane ...
Phys.org / Melting sea ice combines with Arctic sea to make clouds
Scientists have uncovered a previously unknown natural process that dramatically increases the number of cloud-forming particles in the Arctic atmosphere—potentially altering cloud cover, sunlight reflection and future climate ...
Phys.org / Attosecond X-ray method maps early electron motions that trigger chemical reactions
All chemistry starts with a push from electrons. In the early moments of a chemical reaction, it's the movement of electrons that initiates the breaking of old chemical bonds and forging of new ones, transforming one molecule ...
Phys.org / We might soon have the technology to reach other star systems
The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star—a red dwarf ...
Phys.org / Sizing errors can hide true nanoparticle behavior
Nanoscience, which studies small objects, has a big problem. According to a team of scientists at the National Institute of Standards and Technology (NIST), the field confronts a pervasive data analysis error that can give ...
Phys.org / 'Spooky' particles transit DC suburbs, a step toward a quantum network
In early 2025, special signals wended their way through a fiber-optic highway strung above the streets and sidewalks of the Maryland suburbs. The arrival of those signals at their destination marks a significant step toward ...
Medical Xpress / Mammography use has dropped among some groups, study finds
Researchers at WashU Medicine have found a significant decline in mammography use among certain groups of women. A recent study, led by Adetunji Toriola, MD, Ph.D., a professor of surgery and a William H. Danforth Washington ...
Phys.org / Ancient armored fish that narrowly avoided meteorite strike reveals life before Earth's largest mass extinction
A rare fossil discovered near South America's largest known meteorite crater has been named a new species. Initially mistaken for a frog by locals, Leolepis matogrossensis is actually a species of ancient ray-finned fish—the ...
Phys.org / Harvesting rainwater from rooftops could help cities stay cool and cut the number of heat wave days
Collecting rainwater from rooftops and using it to spray buildings during hot weather could help cities cut air conditioning use, lower urban temperatures and lessen the impact of heat waves, according to new research from ...
