Researchers Find a way to Stop Pig-Organ Transplant Rejection

Medicine, Surgerical Tech /

Scientists have managed to prevent the rejection of a pig kidney transplanted into a human donor. The organ continued to function for 61 days in a 57-year-old brain-dead man in the United States — the longest a genetically engineered pig organ has ever lasted in a brain-dead human. In two studies published today in Nature,

Studies Show Husbands Stress Women more than Children

Medical Care, Medicine /

Raising a child is anything but easy, particularly during the early years when parents encounter ongoing challenges. However, a survey by the American website Today.com found that for many women, their husbands—not their children—are the primary source of stress. Among the 7,000 mothers surveyed, the average stress level was 8.5 out of 10. Notably, 46%
