    We may now know when hand, foot and mouth disease outbreaks will occur

    Enteroviruses, including the ones that cause hand, foot and mouth disease, trigger outbreaks in predictable patterns.

    Some of these viruses, which can lead to everything from fevers, rashes and blisters to meningitis and heart infections, circulate every year or every two or three years. But it’s been unclear how foreseeable those patterns are. Now, based on Japan’s birthrate and how...

    Readers question dark fusion, Antarctic ice melting and more

    Melt away

    In the last five years, Antarctica has lost ice nearly three times faster on average than it did over the previous 20 years — largely due to climate change, Laurel Hamers reported in “Antarctica has lost about 3 trillion metric tons of ice since 1992” (SN: 7/7/18, p. 6).

    “Isn’t there a volcano or multiple volcanoes recently found under Antarctica that might also be...

    Nasty stomach viruses can travel in packs

    Conventional wisdom states that viruses work as lone soldiers. Scientists now report that some viruses also clump together in vesicles, or membrane-bound sacs, before an invasion. Compared with solo viruses, these viral “Trojan horses” caused more severe infections in mice, researchers report August 8 in Cell Host & Microbe.

    Cell biologist Nihal Altan-Bonnet had been involved in...

    The right mix of gut microbes relieves autism symptoms in the long run

    MADISON, Wis. — Giving children with autism a healthier mix of gut bacteria as a way to improve behavioral symptoms continued to work even two years after treatment ended.

    The finding may solidify the connection between tummy troubles and autism, and provide more evidence that the gut microbiome — the collection of bacteria and other microbes that live in the intestines — can influence...

    Bobtail squid coat their eggs in antifungal goo

    MADISON, Wis. — When eggs go bad, bacteria usually get the blame. But some bacteria help bobtail squid keep their eggs fresh.

    Bacteria that female Hawaiian bobtail squid (Euprymna scolopes) deposit in the jelly surrounding their eggs can fight off a fungus called Fusarium keratoplasticum, Spencer Nyholm reported July 9 at the Beneficial Microbes Conference.

    A specialized organ...

    Finally, there’s a way to keep syphilis growing in the lab

    For more than a century, scientists have tried to grow Treponema pallidum, the corkscrew-shaped bacterium that causes syphilis. But the stubborn spirochete has refused to thrive any place outside of a human or rabbit for more than 18 days. That doesn’t give researchers much time to study it.

    “I’ve basically spent my entire career watching these organisms die,” says microbiologist Steven...

    Leprosy lurks in armadillos in Brazil’s Amazon

    Brazilians who hunt or eat armadillos are at a higher risk of catching leprosy than people who don’t interact with the animals, a new study finds.

    More than 60 percent of armadillos tested in Brazil’s Amazonian state of Pará carry the leprosy bacterium Mycobacterium leprae. And about 63 percent of people tested in two villages in the region have antibodies against the bacterium,...

    Zika gets the most extreme close-up of any flavivirus

    Researchers have gotten the closest look ever at Zika virus and may have discovered some chinks in its armor.

    Using cryo-electron microscopy, structural biologist Madhumati Sevvana and colleagues mapped Zika’s structure at 3.1-angstrom (or 0.31-nanometer) resolution. That closeup view, reported online June 26 in Structure, is about equivalent to the size of two atoms. It’s the most...

    Dogs carry a surprising variety of flu viruses

    Some dogs in China carry a mixed bag of influenza viruses. The discovery raises the possibility that dogs may be able to pass the flu to people, perhaps setting off a pandemic.

    About 15 percent of pet dogs that went to the vet because of respiratory infections carried flu viruses often found in pigs, researchers report June 5 in mBio. Of the virus strains detected, three have recombined...

    Your blood type might make you more likely to get traveler’s diarrhea

    E. coli has a type and it isn’t pretty. The bacterium is more likely to cause severe diarrhea in people with type A blood.

    An illness-causing strain of E. coli secretes a protein that gloms onto the sugar molecules that decorate type A blood cells, but not type B or O cells. These sugar molecules also decorate cells lining the intestines of people with type A blood and appear to provide...
