Astronomers have caught their best look ever at blobs of hot gas fleeing a supermassive black hole, thanks to a new kind of cosmic magnifying glass.
Anthony Readhead of the Owens Valley Radio Observatory at Caltech and colleagues caught two small, hot bursts traveling away from a bright galaxy called J1415+1320 at near the speed of light. Although the galaxy is billions of light-years...
Add a new ingredient to the sugar, spice and everything nice needed to make girls.
A protein called COUP-TFII is necessary to eliminate male reproductive tissue from female mouse embryos, researchers report in the Aug. 18 Science. For decades, females have been considered the “default” sex in mammals. The new research overturns that idea, showing that making female reproductive organs is...

Everybody poops, but the poop of bloblike filter feeders called giant larvaceans could be laced with microplastics.
Every day, these gelatinous creatures (Bathochordaeus stygius) build giant disposable mucus mansions to round up zooplankton into their stomachs — sometimes sifting through around 80 liters of seawater per hour. Kakani Katija and her colleagues at the...
In deciding on a cover image for this issue, the Science News team had a difficult choice to make: Do we print a picture of a tick that reminds readers how much we all despise these critters? Or, do we go with a closeup view that masks ticks’ revolting character and makes you wonder: “Ooh. What’s that?” We chose to highlight hostilities to match the story headline, “Bulletins from the tick...

Tubelip wrasses’ slimy lips help the fish suck up dinner from coral reefs, Helen Thompson reported in “The better to eat you with, my dear” (SN: 7/8/17 & 7/22/17, p. 44).
“How do wrasses ‘suck’ if they have no lungs?” asked reader John Coventry.
Suction-feeding fish let their mouths do all the work, says marine biologist David Bellwood. “In just the same way that we...
Thanks, Holly Gaff. Soon, anyone straining to tweeze off a mid-back tick can find answers to the obvious question: What if humankind just went after the little bloodsuckers with killer robots?
Gaff, who calls herself a mathematical ecoepidemiologist, at Old Dominion University in Norfolk, Va., is one of the few people collecting real field data on the efficacy of tick-slaying robots....
Some deep-sea tube worms get long in the tooth ... er, tube. Living several decades longer than its shallow-water relatives, Escarpia laminata has the longest known life span for a tube worm, aging beyond 300 years, researchers report in the August Science of Nature.
E. laminata lives 1,000 to 3,300 meters deep in the Gulf of Mexico, near seafloor vents that seep energy-rich compounds...
Remains of at least two Late Bronze Age initiation ceremonies, in which teenage boys became warriors by eating dogs and wolves, have turned up in southwestern Russia, two archaeologists say. The controversial finds, which date to between roughly 3,900 and 3,700 years ago, may provide the first archaeological evidence of adolescent male war bands described in ancient texts.
Select boys of...
If Lewis Carroll were alive today, he wouldn’t bother with a looking glass. His book would be called Alice Through the Wormhole.
Being the mathematician that he was, Carroll (aka Charles Dodgson) would have kept current with the latest developments in quantum physics. He would no doubt be intrigued by a new paper describing an idea for the creation (or at least the simulation) of a...

A couple of weeks ago, an article in New York magazine laid out a horrific scenario of global warming. The photo at the top summed up the tone: A fossilized human skull, jaw gaping beneath aviator sunglasses, hovered over a caption warning that people could be “cooked to death from both inside and out” in a hotter climate.
If that’s not doom and gloom, I don’t know what is. Yet despite...
