Medical Xpress / Surprising new roles discovered for known blood cancer gene DNMT3A
A gene called DNMT3A is important for guiding blood stem cells into forming all the cell types present in blood, including red blood cells, white blood cells and platelets. When this gene accumulates mutations—which might ...
Medical Xpress / Study finds primary-care doctors often overlook prostate cancer risk in Black men
Although Black men die of prostate cancer at twice the rate of the rest of U.S. males, this fact often is not known or considered during appointments with their primary-care clinicians to discuss a common screening test.
Phys.org / Britain's economy did not collapse after the Romans left, sediment core analysis finds
Researchers have examined a sediment core from the Roman town and metal production center of Aldborough in Yorkshire, revealing metal production did not collapse immediately after the Romans left Britain.
Phys.org / Tiny prairie dwellers outshine bison in keeping soil and plant nutrients cycling
Soil nutrients support plants, and the animals who consume plants return these nutrients to the soil, creating a nutrient cycle. In a new study published in Ecology, scientists from the Smithsonian's National Zoo and Conservation ...
Medical Xpress / Customized gene-editing technology shows potential to treat lethal pediatric disease
Multisystemic smooth muscle dysfunction syndrome (MSMDS) is a rare condition associated with stroke, aortic dissection (tearing) and death in childhood. Currently, there is no effective treatment or cure for MSMDS.
Medical Xpress / Cell defect in exosomes linked to development of Alzheimer's
They're tiny particles—with potentially huge human consequences. Researchers from Aarhus University have identified a defect in the production of so-called exosomes in cells, associated with a mutation seen in dementia ...
Phys.org / Warming rivers in Alaska threaten Chinook salmon populations and Indigenous food security
For millennia, Indigenous people living in Alaska and Canada's Yukon territory have relied on Chinook salmon. The large, fatty fish provide essential nutrients for Arctic living and have influenced traditions and languages ...
Phys.org / Octopuses put their best arm forward for every task
Octopuses can use any of their arms to perform tasks, but tend to use a particular arm, or arms, for specific tasks. This finding, presented in a paper in Scientific Reports, reveals more about the complex behavior these ...
Phys.org / First-ever complete measurement of a black-hole recoil achieved thanks to gravitational waves
A team of researchers led by the Instituto Galego de Física de Altas Enerxías (IGFAE) from the University of Santiago de Compostela (Spain) has measured for the first time the speed and direction of the recoil of a newborn ...
Phys.org / INTEGRAL observes exceptionally bright X-ray flares from Cygnus X-1
Using ESA's INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system ...
Phys.org / Octopus arms reveal specialized movements and coordination in the wild
Octopuses are among the most neurologically complex invertebrates, famed for their extraordinary dexterity. Their eight arms allow them to capture hidden prey, communicate, explore, and even mate across varied habitats.
Tech Xplore / Europe hyperloop test hits new speed record in Dutch trial
A Dutch tech startup said Wednesday it had set a European speed record for its futuristic hyperloop transport system and could reach 700 kilometers (435 miles) per hour once longer tracks are built.
