From 2007 to 2016, the U.S. Food and Drug Administration flagged nearly 800 over-the-counter dietary supplements as tainted with potentially harmful pharmaceutical drugs, a study shows. Fewer than half of those products were recalled by their makers, scientists found.
Researchers analyzed the FDA’s public database of tainted supplements, identifying both the type of contaminating...

Humans took a long, weird road to modern medicine. We don’t have everything figured out yet, but at least we’ve learned not to drink the feces of cholera victims and never to plug dental cavities with a lizard’s liver — unlike some of our ancestors.
Gruesome methods like these...
A city itself influences the contours of its flu season – whether flu cases rise to a wintertime peak or plateau from fall to spring, new research suggests.
Flu cases generally peak in winter in certain areas of the United States because the air is drier. That dryness helps the flu virus survive longer once sneezed out of a sick person, for example, allowing the virus to potentially...
In the past year, the flu killed an estimated 80,000 Americans — the country’s highest death toll from flu and related complications in more than a decade, according to the U.S. Centers for Disease Control and Prevention.
The 2017–2018 flu season has been classified as one of “high severity” (SN: 7/7/18, p. 16), with some 900,000 people hospitalized with flu symptoms — the highest...

Chemist Emily Balskus of Harvard University is out to expose the crimes and misdemeanors of microbes living in the human gut. She’s shown, for example, how a common gut bacterium interferes with a heart failure treatment: The microbe breaks down the medication before the drug can do its job.
Balskus, 38, originally...

Jenny Tung is skeptical when she hears that her older sister, Wenny, compares Jenny’s science to their father’s golf.
He played so much because he found it “a big, fat, hairy challenge,” Wenny said, proposing that Jenny, too, is drawn to challenges by their difficulty.
Jenny Tung protests. Yet she doesn’t deny...
A new tuberculosis vaccine shows promise in preventing the bacteria from causing disease in people who are infected, but aren’t sick. If approved, it could help control the spread of a disease considered one of the world’s top killers, responsible for 1.6 million deaths in 2017, according to the World Health Organization.
In a clinical trial, the new vaccine halved the number of people...
Girding against a new strain
Flu comes in many kinds, and the current vaccine … has little effect against a newcomer that has afflicted at least 400,000 persons in Hong Kong. The Asian city was the source of the 1957 epidemic in the United States. Fears that it may provide a springboard for another one have caused the Public Health Service to ask eight pharmaceutical companies to...

It took a close look at crystal formation in Yellowstone’s hot springs to understand stones much closer to home. Growth and dissolution patterns found in rocks there mirror what’s going on with stones in our kidneys, says Bruce Fouke, a geobiologist at the University of Illinois at Urbana-Champaign, contradicting the medical dogma that kidney stones don’t dissolve.
Fouke, who usually...
