A man let snakes bite him 202 times. His blood helped create a new antivenom

2 weeks ago | sciencenews.org | Meghan Rosen

The first was from an Egyptian cobra. The second, an hour later, from a monocled cobra. Both bites occurred at his home in Wisconsin. Both were from highly venomous snakes. Neither bite was an accident. Friede let the cobras bite him on purpose — now, he’s logged 202 snakebites, in total. “It always burns and it’s always, always painful,” he says. After the back-to-back cobra bites, Friede had to be airlifted to the hospital and spent four days in a coma. “Was it a mistake? Yes. Was it stupid?

Ozempic and Wegovy ingredient may reverse signs of liver disease

The diabetes and weight loss drug semaglutide may also reverse signs of liver disease. That’s the headline result of a new clinical trial that tested the popular medication in patients with MASH, or metabolic dysfunction-associated steatohepatitis. The disease is marked by fat droplets piling up in liver cells, chronic inflammation and scar tissue in the liver. But a 72-week regimen of semaglutide seemed to turn the disease around.

Cathy Raley’s first bout of hives woke her in the middle of the night with itchy bumps that crept up her arms and spread to her legs and back. Her second bout took her to the hospital. It was a June afternoon in 2017, and she was getting ready to take her dog, Jake, on a hike. The hives started suddenly, when she was about to load Jake into the car, but this time was different, Raley says. Her tongue was swelling, and her throat was getting tight.
The story of dire wolves goes beyond de-extinction

1 month ago | sciencenews.org | Meghan Rosen

Their names are Romulus, Remus and Khaleesi, and they’re the first dire wolves to walk the Earth in over 10,000 years — or so one biotech company and a flurry of recent headlines say. On April 7, Colossal Biosciences announced what they called the “world’s first de-extinction,” the births of three dire wolves, extinct animals that lived during the ice ages of the Pleistocene. The pups were instant icons.
A shadowy market for weight-loss drugs has emerged online

In late 2022, pharmacist Joseph Lambson got an unusual call from a poison control specialist. He said, “Hey Joe, I’m getting these weird calls about semaglutide.” According to the specialist’s calculations, people were giving themselves 10 times the correct dose. But that didn’t make sense. The drug is the key ingredient in the blockbuster diabetes and weight-loss medications Ozempic and Wegovy. Both come in prefilled injector pens, which typically take the guesswork out of dosing.
Surgeons transplanted a pig’s liver into a human

Surgeons have now published the first report of a gene-edited pig liver transplanted into a person. The liver, which came from a genetically modified pig, appeared to stay active, producing bile and liver proteins inside the brain-dead transplant recipient, researchers reported March 26 in Nature. Such a transplant could one day buy time for people waiting on the liver transplant list.

An mRNA cancer vaccine may offer long-term protection

A new mRNA vaccine could prevent pancreatic cancer from returning — potentially for the long haul. In a small clinical trial, some patients who received the vaccine remained cancer-free for more than three years, researchers reported February 19 in Nature. That is “pretty remarkable,” says Aaron Sasson, who directs the Pancreatic Cancer Center at Stony Brook Medicine in New York and was not involved with the work.
