Roy Calne, a British surgeon whose work on organ transplantation helped turn what was once considered impossible into a lifesaving procedure for millions of people around the world, died on Jan. 6 at a retirement home in Cambridge, England. He was 93.His son Russell Calne said he died from heart failure.There are groundbreaking surgeons and groundbreaking researchers, but very few people are both. Dr. Calne (pronounced “kahn”) was an exception: He developed and practiced many of the operating techniques involved in transplantation, while at the same time working to identify what drugs would get the body to accept a new…

A panel of experts affiliated with the United Nations has warned that the population of the Gaza Strip is at imminent risk of famine, with more than 90 percent of its 2.2 million people facing “acute food insecurity” and a quarter of the population experiencing “catastrophic levels of hunger.”Even before the war between Israel and Hamas, nearly 70 percent of Gazans were dependent on humanitarian assistance for food because the territory has been under Israeli and Egyptian blockade since 2007. Now, only 20 to 30 percent of what people there need is being permitted over the border into Gaza, according…

Multiple sclerosis, an autoimmune disease that affects 2.9 million people, presents a biological puzzle.Many researchers suspect that the disease is triggered by a virus, known as Epstein-Barr, which causes the immune system to attack the nerves and can leave patients struggling to walk or talk. But the virus can’t be the whole story, since nearly everyone is infected with it at some point in life.A new study found a possible solution to this paradox in the skeletal remains of a lost tribe of nomads who herded cattle across the steppes of western Asia 5,000 years ago. It turns out that…

As Covid rises again, killing about 1,500 Americans each week, medical researchers are trying to understand why so few people are taking Paxlovid, a medicine that is stunningly effective in preventing severe illness and death from the disease.A study of a million high-risk people with Covid found that only about 15 percent who were eligible for the drug took it. If instead half of the eligible patients in the United States had gotten Paxlovid during the time period of the research, 48,000 deaths could have been prevented, the authors of the study, conducted by the National Institutes of Health, concluded.It’s…

Monique Louvigny, an event coordinator in the San Francisco Bay Area, economizes where she can. She drives a 10-year-old Prius, brings a thermos of coffee to work instead of patronizing a place with baristas, and takes advantage of a drive-through food pantry once a month.Laid off at 57, “I kind of reinvented myself,” she said. She rebuilt her career as a freelancer, overseeing receptions and conventions for many companies and institutions, including the local de Young and Legion of Honor art museums.But her income fell to less than $30,000 last year. “It’s erratic,” she said. “In January, I have 12…
