Scientists found a sugar that could defeat deadly superbugs

Scientists in Australia have uncovered a clever new way to fight some of the most dangerous drug-resistant bacteria by targeting a sugar that exists only on bacterial cells. By designing antibodies that recognize this unique sugar, researchers were able to guide the immune system to attack and eliminate deadly infections that normally shrug off antibiotics.

Common pneumonia bacterium may fuel Alzheimer’s disease

A common bacterium best known for causing pneumonia and sinus infections may also play a surprising role in Alzheimer’s disease. Researchers found that Chlamydia pneumoniae can invade the retina and brain, where it sparks inflammation, nerve cell death, and the buildup of amyloid-beta—the hallmark protein linked to Alzheimer’s. Higher levels of the bacterium were found in people with Alzheimer’s, especially those carrying the high-risk APOE4 gene, and were tied to more severe cognitive decline.

One stem cell generates 14 million tumor-killing NK cells in major cancer breakthrough

Scientists in China have unveiled a breakthrough way to mass-produce powerful cancer-fighting immune cells in the lab. By engineering early-stage stem cells from cord blood—rather than trying to modify mature natural killer (NK) cells—they created a streamlined process that generates enormous numbers of highly potent NK cells, including CAR-equipped versions designed to hunt specific cancers.

Ultramarathons may damage red blood cells and accelerate aging

Running extreme distances may strain more than just muscles and joints. New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, potentially interfering with how they deliver oxygen throughout the body. Scientists found signs of both mechanical stress from intense blood flow and molecular damage linked to inflammation and oxidative stress.
