Scientists are increasingly interested in how different exercise intensities can trigger different responses in the body. A new study finds that an all out sprint may have unique benefits.
Older adults who received the Shingrix shingles vaccine were 24% less likely to be diagnosed with dementia over four years in a study of more than 500,000 people. Researchers estimate the difference c
Researchers have found a way to supercharge natural killer cells, powerful immune cells that can attack cancer, so they can penetrate solid tumors and keep fighting once inside. In mice, these special
A major study found that adults with depression show disrupted production of new neurons in the hippocampus, potentially weakening the brain’s ability to separate new experiences from painful memories
People who reach 110 and beyond appear to have unusually large numbers of rare immune cells capable of killing abnormal cells. These CD4 cytotoxic T cells became more common with age and often expande
A Pennsylvania summer camp helps children who have survived brain injuries. But the future of federal funding for brain injury research, and grants to states to help such patients, is in limbo.
A drug bust involving an alleged cocaine ring at Penn State has drawn attention to drug use on college campuses, but the research shows the big risk to students is alcohol.
Common medications may reshape the gut microbiome long after the last dose is taken. In a study of more than 2,500 people, researchers found lasting microbial changes linked not only to antibiotics, b
Backyard bird feeders could become unexpected hotspots for H5N1 as Australia’s bird flu outbreak spreads, bringing species together in ways that rarely occur naturally. Experts say stopping feeding is
Both too little and too much sleep may be linked to faster aging throughout the body. Researchers analyzing 23 biological aging clocks found the lowest aging levels among people sleeping about 6.4 to
A new study finds that an all-out sprint may have unique benefits when it comes to the proteins and tiny molecules in your bloodstream.
Scientists are increasingly interested in how different exercise intensities can trigger different responses, all the way down to the proteins and tiny molecules in our bloodstream. A new study finds
Gut bacteria can transform nitrate and plant-based iron from vegetables and other foods into protective molecules that may benefit the heart and metabolism. In experimental models, higher levels of th
Researchers have uncovered a possible reason why the Alzheimer’s risk gene APOE4 can disrupt the brain long before memory problems begin. In mice, APOE4 increased a protein called Nell2, shrinking neu
Researchers have found a way to slash the processing time for 3D-printed zirconia crowns from as much as 100 hours to under 30 minutes. The advance could eventually let dentists print strong, customiz
Researchers have used AI to uncover the DNA signature of a key genetic “switch” involved in turning genes on. After analyzing about 500,000 DNA sequences, the model identified the initiator in roughly
A decades-old compound may point to a new way of treating obesity by making the body burn more energy rather than simply reducing appetite. In mice, TOFA increased energy use by as much as 18%, reduce
A massive analysis involving more than 100 million people has found strong links between recreational drug use and stroke, including among younger adults. Cocaine was associated with nearly double the
