Why individuals with celiac illness suffer so not long after consuming...

Researchers finally know why people with celiac disease get nauseous within hours of eating gluten. Some immune cells dump stomach-churning levels of immune chemicals called cytokines into the blood soon after the cells encounter gluten, triggering symptoms, scientists report August 7 in Science Advances. “When patients ate gluten, symptoms and cytokines went up at the…

The golf ball–sized chunk of brain is not cooperating. It’s thicker than usual, and bloodier. One side has a swath of tissue that looks, to my untrained eye, like gristle. Nick Dee, the neuroscientist charged with quickly cutting the chunk into neat pieces, confers with his colleagues. “We can trim off that ugliness on the…

Readers ask about measles, vaccine hesitancy and more

Tough choices Discussing shared health goals with vaccine-hesitant parents may help doctors get those parents on board, Aimee Cunningham reported in “Finding common ground can reduce parents’ hesitation about vaccines” (SN: 6/8/19, p. 16). Reader Dona Chilcoat objected to a photo in the story that showed a crying baby getting a shot. She thought the…

Improving a gut germs assists mice battle an ALS-like illness

A friendly gut bacterium can help lessen ALS symptoms, a study of mice suggests. Mice that develop a degenerative nerve disease similar to amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease, fared better when bacteria making vitamin B3 were living in their intestines, researchers report July 22 in Nature. Those results suggest that gut microbes…

Frances Mercer runs a fight club. In one corner, the parasite Trichomonas vaginalis, which causes a widespread sexually transmitted infection that many people have never heard of. In the other corner are neutrophils, the immune system cells best equipped to take down the aggressor. Watching the two battle it out, Mercer, an immunoparasitologist at California…

Dealing with cystic fibrosis clients prior to birth might protect organs

A drug that treats a rare form of cystic fibrosis may have even better results if given before birth, a study in ferrets suggests. The drug, known by the generic name ivacaftor, can restore the function of a faulty version of the CFTR protein, called CFTRG551D. The normal CFTR protein controls the flow of charged…
Baboons endure 6 months after getting a pig heart transplant

Baboons endure 6 months after getting a pig heart transplant

For roughly six months, fully functioning pig hearts beat inside the chests of two Anubis baboons. Genetic modifications to the pig hearts along with a new transplant technique are credited with the longest-yet survival after such a transplant, researchers report December 5 in Nature. Previously, the longest a baboon lived after such a procedure was…
