Researchers have found a reliable way to grow helper T cells from stem cells, solving a major challenge in immune-based cancer therapy. Helper T cells act as the immune system's coordinators, helping other immune cells fight longer and harder. The .. ...

Scientists have uncovered a surprising reason why some chronic wounds refuse to heal, even when treated with antibiotics. A common bacterium found in long-lasting wounds does not just resist drugs. It actively releases damaging molecules that ...

Scientists have uncovered new clues about why diabetic foot infections can become so severe and difficult to treat. By analyzing the DNA of E. coli bacteria taken from infected wounds around the world, researchers found an unexpected level of ...

A nearby active galaxy called VV 340a offers a dramatic look at how a supermassive black hole can reshape its entire host. Astronomers observed a relatively weak but restless jet blasting outward from the galaxy's core, wobbling like a spinning top . ...

NASA's Artemis II rocket has reached its launch pad after a painstaking overnight crawl across Kennedy Space Center. Engineers are now preparing for crucial fueling and countdown tests ahead of the first crewed Artemis mission. The mission will send ...

Long before humans became master hunters, our ancestors were already thriving by making the most of what nature left behind. New research suggests that scavenging animal carcasses wasn't a desperate last resort, but a smart, reliable survival ...
