Scientists replayed evolution and found a surprise
All living things must survive in environments that are constantly changing. Seasons shift from summer to winter, and weather patterns can swing from floods one year to drought the next.…
Scientists found a dangerous feedback loop accelerating Arctic warming
Earth’s climate is shifting worldwide, but the fastest changes are happening near the poles. New research from Penn State offers a detailed look at how chemical reactions in the Arctic…
MIT scientists find a way to rejuvenate the immune system as we age
As people get older, the immune system often becomes less effective. Populations of T cells shrink, and the remaining cells may respond more slowly to germs. That slowdown can leave…
Stanford scientists uncover why mRNA COVID vaccines can trigger heart inflammation
Researchers at Stanford Medicine have identified the biological steps that explain how mRNA-based COVID-19 vaccines can, in rare cases, lead to heart inflammation in some adolescent and young adult males.…
Scientists found a way to restore brain blood flow in dementia
A potential new way to treat reduced brain blood flow and certain forms of dementia is beginning to emerge. Scientists at the University of Vermont Robert Larner, M.D. College of…
Scientists reverse Alzheimer’s in mice and restore memory
A study reveals that restoring the brain’s energy balance may not just slow Alzheimer’s — but actually reverse it. For more than a century, Alzheimer’s disease has been widely viewed…
MIT scientists strip cancer of its sugar shield
A research team from MIT and Stanford University has developed a new technique designed to push the immune system to go after tumor cells. The strategy is aimed at helping…
The 98% mystery: Scientists just cracked the code on “junk DNA” linked to Alzheimer’s
When people picture DNA, they often imagine a set of genes that shape our physical traits, influence behavior, and help keep our cells and organs functioning. But genes make up…
A quantum mystery that stumped scientists for decades is solved
A global research team led by Rice University physicist Pengcheng Dai has verified the presence of emergent photons and fractionalized spin excitations in an unusual quantum spin liquid. Reported in…
Scientists find dark chocolate ingredient that slows aging
A natural chemical in dark chocolate may play a role in slowing certain signs of biological aging. Researchers at King’s College London have identified theobromine, a plant compound found in…
