With a mortar and pestle, Christy Till blends together the makings of a distant planet. In her geology lab at Arizona State University in Tempe, Till carefully measures out powdered minerals, tips them into a metal capsule and bakes them in a high-pressure furnace that can reach close to 35,000 times Earth’s atmospheric pressure and 2,000° Celsius.
In this interplanetary test kitchen,...
Starve the tumor, not the cell
Animal experiments demonstrate for the first time that transplanted tumors release a chemical into the host’s bloodstream that causes the host to produce blood vessels to supply the tumor.… If such a factor can be identified in human cancers … it might be possible to prevent the vascularization of tumors. Since tumors above a certain small size require...
Pick an animal.
Choose wisely because in this fantasy you’ll transform into the creature and duel against one of your own. If you care about survival, go for the muscular, multispiked stag roaring at a rival. Never, ever pick the wingless male fig wasp. Way too dangerous.
This advice sounds exactly wrong. But that’s because many stereotypes of animal conflict get the real biology...
Subscribers to Science News may note that this special double issue is a lot heftier than the usual magazine, boasting more than 20 pages of advertisements. That’s up from 13 pages in last spring’s expanded issue.05/02/2018 - 07:15 Science & Society
Indeed, our ace marketing department sold so many ads that we had to include more articles, which, as anyone in print publishing will tell you, is a very nice problem to...

Physicists are ramping up their search for neutrinoless double beta decay, which could help explain why there is more matter in the universe than antimatter, Emily Conover reported in “The quest to identify the nature of the neutrino’s alter ego is heating up” (SN: 3/17/18, p. 14).
Reader F L Stiles wondered how this decay could explain a surplus of matter. “It...
Nicholas Blackwell and his father went to a hardware store about three years ago seeking parts for a mystery device from the past. They carefully selected wood and other materials to assemble a stonecutting pendulum that, if Blackwell is right, resembles contraptions once used to build majestic Bronze Age palaces.
With no ancient drawings or blueprints of the tool for guidance, the two...
In the pitch-black waters beneath the Arctic ice, bowhead whales get funky. A small population of endangered bowheads belt an unusually varied repertoire of songs, which grows more diverse during mating season.
Hunted to near extinction in the 1600s, these fire truck–sized mammals now number in the 300s in the frigid waters around the Svalbard archipelago in Norway. Underwater audio...

The Curious Life of Krill Stephen NicolIsland Press, $30
Stephen Nicol is here to change your mind about krill: They’re not microscopic and they’re far from boring. The biologist is so sick of people misunderstanding his study subjects that he’s even gotten a (slightly botched) krill tattooed on his arm to help enlighten strangers.
In The Curious Life of Krill, Nicol is taking...
It’s no secret that warming ocean waters have devastated many of the world’s coral reefs. For instance, a 2016 marine heat wave killed 30 percent of coral in the Great Barrier Reef, a study published online April 18 in Nature reports. But some coral species may be able to adapt and survive in warmer waters for another century, or even two, a second team reports April 19 in PLOS Genetics. And...

In turquoise waters off the Indonesian coast, evolutionary geneticist Melissa Ilardo watched as the diver, wearing handmade, wooden goggles, spotted a giant clam meters below and darted down to retrieve it.
The diver was one of the Bajau people of Southeast Asia, known for holding their breath for long periods while spearing fish and gathering other seafood. During a typical day, these “...
