On Oct. 19, researchers at the University of Hawaii Institute for Astronomy spotted a strange guest in the night sky: a quarter-mile-wide hunk of space rock hurtling through our solar system, the first “interstellar visitor” ever observed by scientists.

“Spacecraft, like Stardust, have captured interstellar dust,” says Meenakshi Wadhwa, director of the Center for Meteorite Studies at Arizona State University. “And there’s actually interstellar dust in meteorites, too. But this is the first object that’s macro in size.”

Scientists are figuring out that our microbiomes — those multitudes of bacteria, viruses and fungi in our guts — affect far more than digestion. Researchers writing recently in the journal, Science, describe how the microbiomes of people with melanoma even interact with their cancer treatment.

What’s the best way to test for partisan gerrymandering?

In October, the United States Supreme Court heard oral arguments for Gill v. Whitford, a landmark case about gerrymandering in Wisconsin. Democratic plaintiffs proposed an easy formula — called the efficiency gap — to determine whether an electoral district is fairly drawn.

A scientist who finds pharmaceutical promise in the venom of cone snails

Nov 18, 2017

Nestled inside its bright, patterned shell, the cone snail cuts a familiar figure in tropical waters — you may have even collected its shell on a walk along the beach. But watch your touch — every species of cone snail is venomous, and some, like Conus geographus, can even kill humans.

CAPTCHAs — think those little forms with jumbles of letters and numbers — have long been the Web’s gatekeepers between humans and robots. Short for “Completely Automated Public Turing test to tell Computers and Humans Apart,” the tests are meant to be too complex for computers to solve.

If you’re afraid of spiders, join the club: Catherine Scott and Eleanor Spicer Rice have been right there with you.

“I used to be terrified of spiders until I was about 25 years old and started studying them,” Scott says. These days, she’s an arachnologist and Ph.D. student at the University of Toronto. Rice, for her part, is now an entomologist with a book, “Dr. Eleanor’s Book of Common Spiders,” due out this winter.

What can fly, swim and dive? This tiny robotic insect.

Imagine going to the beach and catching sight of a bee buzzing past you, then watching as it dives into the water, swims below the surface and shoots back into the air a few seconds later.

In a long-ago neutron star collision, scientists find a cosmic goldmine

Nov 6, 2017

Around 130 million years ago, two neutron stars — those strange, compacted cores of dead stars — smashed into one another. The resulting “kilonova” explosion sent ripples through space-time and hurtled heavy metals like platinum and gold into space. Now, astronomers have detected the signals from that long-ago collision, in the form of gravitational waves and electromagnetic signals.

The United States’ newly revived National Space Council recently met for the first time, and in a speech before the council — tasked with setting the country’s space agenda — Vice President Mike Pence called for a return to the moon and the development of a base there.
