Pathogen detectors built into plastic patches could someday spare you food poisoning.
Carlos Filipe, a chemical engineer at McMaster University in Hamilton, Canada, and colleagues have developed a new kind of flexible film that’s coated in molecules that glow when they touch E. coli cells. This type of sensor also glows in the presence of molecules secreted by E. coli, so the material...
How a nasty, contagious stomach virus lays claim to the digestive system just got a little less mysterious.
In mice, norovirus infects rare cells in the lining of the gut called tuft cells. Like beacons in a dark sea, these cells glowed with evidence of a norovirus infection in fluorescent microscopy images, researchers report in the April 13 Science.
If norovirus also targets...
Mexico takes vaccine to hinterland04/10/2018 - 15:00 Health
The campaign to eradicate measles in Mexico is going into the hinterland areas. Mobile brigades will use live virus vaccine produced in laboratories of the Republic’s Department of Health. Measles kills 10,000 Mexican children a year. — Science News, April 13, 1968Update
The last measles case to originate in Mexico occurred in 1995. In 2016...
News in Brief
Hot peppers aren’t just a pain in the mouth — they may be a pain in the head, too. After eating the hottest known pepper in the world, a man suffered from splitting headaches that drove him to the hospital emergency room, and into case-study history.
His is the first known instance of reversible cerebral vasoconstriction syndrome — a temporary narrowing of arteries in the brain — to be...

A deep conviction that one’s skin is contaminated with insects or other objects despite a lack of medical evidence.
She was certain her skin was infested: Insects were jumping off; fibers were poking out. Fearful her condition could spread to others, the 50-year-old patient told doctors at the Mayo Clinic in Rochester, Minn., that...
An unknown killer preying on pigs in China has been identified as a new kind of coronavirus. And like the deadly SARS virus, this one also got its start in bats.
In late 2016, pigs mysteriously started having intense diarrhea and vomiting on farms in China’s southeastern Guangdong province. By May 2017, the disease had killed 24,693 piglets. Tests failed to pin the outbreak, which has...
Some victims were found at home. An 84-year-old woman who’d spent over half her life in the same Sacramento, Calif., apartment died near her front door, gripping her keys. A World War II veteran succumbed in his bedroom. Many died outside, including a hiker who perished on the Pacific Crest Trail, his water bottles empty.
The killer? Heat. Hundreds of others lost their lives when a...
In the United States, cartoon characters are a no-no in cigarette ads, and candy- or fruit-flavored cigarettes can’t be sold. But that’s not the case for e-cigarettes, and these youth-appealing tactics are luring teens who have never used tobacco products to give e-cigs and even cigarettes a try, a new study suggests.
Researchers analyzed surveys of nearly 7,000 kids ages 12 to 17 who...
NEW ORLEANS — Viruses engineered into “nanobots” can find and separate bacteria from food or water.
These viruses, called bacteriophages or just phages, naturally latch onto bacteria to infect them (SN: 7/12/03, p. 26). By tweaking the phages’ DNA and decking them out with magnetic nanoparticles, researchers created a tool that could both corral bacteria and force them to reveal...
