    Here’s what robots could learn from fire ants

    Robots, take note: When working in tight, crowded spaces, fire ants know how to avoid too many cooks in the kitchen.

    Observations of fire ants digging an underground nest reveal that a few industrious ants do most of the work while others dawdle. Computer simulations confirm that, while this strategy may not be the fairest, it is the most efficient because it helps reduce overcrowding in...

    A new computer program generates eerily realistic fake videos

    “The camera never lies” is a thing of the past.

    A new computer program can manipulate a video such that the person on-screen mirrors the movements and expressions of someone in a different video. Unlike other film-fudging software, this program can tamper with far more than facial expressions. The algorithm, to be presented August 16 at the 2018 SIGGRAPH meeting in Vancouver, also tweaks...

    Scientists successfully transplant lab-grown lungs into pigs

    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. That’s a significant improvement from previous efforts: Lab-grown lungs implanted in rodents failed...

    Google Glass could help children with autism socialize with others

    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...

    People are bad at spotting fake news. Can computer programs do better?

    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...

    Readers share their experiences with DNA ancestry tests

    Hacking it

    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.”

    A control...

    What does fake news look like to you?

    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.”

    I find the conversations we have...

    A new kind of spray is loaded with microscopic electronic sensors

    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...

  • 50 years ago, scientists took baby steps toward selecting sex

    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...

    This colorful web is the most complete look yet at a fruit fly’s brain cells

    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...
