For the first time, researchers have created lungs in the lab and successfully transplanted them into pigs.
These bioengineered lungs, described online August 1 in Science Translational Medicine, developed healthy blood vessels that allowed pigs to live for several weeks after surgery without medical complications. That’s a significant improvement from previous efforts: Lab-grown lungs...
Google Glass may have failed as a high-tech fashion trend, but it’s showing promise as a tool to help children with autism better navigate social situations.
A new smartphone app that pairs with a Google Glass headset uses facial recognition software to give the wearer real-time updates on which emotions people are expressing. In a pilot trial, described online August 2 in npj Digital...
Scrolling through a news feed often feels like playing Two Truths and a Lie.
Some falsehoods are easy to spot. Like reports that First Lady Melania Trump wanted an exorcist to cleanse the White House of Obama-era demons, or that an Ohio school principal was arrested for defecating in front of a student assembly. In other cases, fiction blends a little too well with fact. Was CNN really...

Fleets of autonomous taxis coordinated by an algorithm could curb traffic congestion and vehicle pollution, Maria Temming reported in “Fleets of self-driving taxis could be choreographed to cut traffic” (SN: 6/23/18, p. 5).
“And what happens when the system gets hacked?” asked online reader RME76048. “Sounds like a primo target for an ambitious hacker.”
Journalists work hard to communicate science to the public, and we use more than words to do it. Visuals are vital tools in our journalistic kit, whether it’s a graphic explaining the relationship between two datasets, as in the bar chart on how people share fake news on social media, or the cover image of a wad of bills that clearly says “money.”07/25/2018 - 07:00 Science & Society, Technology

Talk about cloud-connected devices.
Using tiny 2-D materials, researchers have built microscopic chemical sensors that can be sprayed in an aerosol mist. Spritzes of such minuscule electronic chips, described online July 23 in Nature Nanotechnology, could one day help monitor environmental pollution or diagnose diseases.
Each sensor comprises a polymer chip about 1 micrometer thick...
Toward preselected sex
Robert Edwards and Richard Gardner of Cambridge University … say they have been able to remove rabbit embryos … then reimplant only the blastocysts destined to develop into the chosen sex. The implications are obvious and enormous. If this procedure could be extended easily to man there might, for instance, be imbalances, even fads, in the selection by parents...
If the secret to getting the perfect photo is taking a lot of shots, then one lucky fruit fly is the subject of a masterpiece.
Using high-speed electron microscopy, scientists took 21 million nanoscale-resolution images of the brain of Drosophila melanogaster to capture every one of the 100,000 nerve cells that it contains. It’s the first time the entire fruit fly brain has been imaged...
Like a submarine Poké Ball, a new robotic device gently captures and releases deep-sea creatures without a scratch. This critter catcher could be decked out with cameras and other sensors to give scientists an unprecedented view of life in one of Earth’s most mysterious environments.
The contraption, designed to be mounted on a remotely operated underwater vehicle, folds into a 12-sided...
News in Brief
A new computer program works smarter, not harder, to solve problems faster than its predecessors.
The algorithm is designed to find the best solution to a given problem among all possible options. Whereas other computer programs winnow down the possibilities one at a time, the new program — presented July 12 at the International Conference on Machine Learning in Stockholm — rules out...
