Robots smaller than most bacteria could deliver drugs right to the site of a brain aneurysm, preventing a devastating stroke, a new animal study suggests. The new technology has been tested only in rabbits so far. But with further study, it could become an alternative to the stents and coils that are currently used to … Read more
Scientists have invented an injectable “goo” that can regrow cartilage in the body. For now, they’ve only tested it in sheep, but it could someday be used to repair joint damage in humans, the researchers say. In particular, they hope the goo can treat damage caused by degenerative diseases, such as osteoarthritis, and sports-related injuries, … Read more
Cancer can sometimes thwart drugs designed to treat it — but now, scientists have developed a way to turn tumor cells against their neighbors, forcing the cancer to cooperate with treatment. A cancer treatment’s success hinges on its capacity to damage cancer cells enough to kill them or stop them from growing. However, some cancer … Read more
For the first time, scientists have tested a messenger RNA (mRNA) vaccine in a patient with a deadly form of brain cancer — and it triggered a strong immune response. The vaccine, which was described in a study published on May 1 in the journal Cell, was created by extracting genetic material called RNA from … Read more
Microplastics may hang around in the body longer than scientists previously thought and may contribute to the spread of cancer when inside tumors, a lab-dish study suggests. The research has several limitations, however. For instance, the scientists used cancer cells grown in lab dishes, so it remains to be seen how the results apply to … Read more
Spaceflight can be a real headache — literally. Since the days of the Apollo program, astronauts have reported experiencing head pain during their stint in microgravity. And many of them had never dealt with recurrent headaches on Earth. It seems that something about space travel sometimes triggers migraine or tension headache–like symptoms, including pain, sensitivity … Read more
A new, flexible device that clings to the neck can translate muscular movements into speech, enabling people to talk without using their vocal cords. The small patch not only detects the movements of the throat associated with speech, but also harnesses that movement to generate electricity, meaning the device can be operated without a battery … Read more
Scientists are working to build blood vessels from human cells using tiny ice sculptures — these frigid 3D forms twist and branch like real arteries and can be used as temporary scaffolds that later get melted away, to be replaced by living cells. The researchers demonstrated the first step of this blood-vessel-building process in a … Read more
For the first time, scientists enabled an amputee to feel temperature via his prosthetic hand, crossing what the researchers say is one of the final hurdles in being able to imbue prosthetics with the full spectrum of senses available in a human limb. The team achieved this feat by implanting a small device in the … Read more
An 81-year-old man from Surrey became the first patient in the U.K. to receive a new “vaccine” designed to treat solid-tumor cancers, such as the skin cancer melanoma. Therapeutic cancer vaccines act as a kind of immunotherapy, meaning they help train the immune system to fight cancer cells. They’re different from vaccines that prevent cancer, … Read more
