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...

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...

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...

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...
