    Electric eels provide a zap of inspiration for a new kind of power source

    New power sources bear a shocking resemblance to the electricity-making organs inside electric eels.

    These artificial electric eel organs are made up of water-based polymer mixes called hydrogels. Such soft, flexible battery-like devices, described online October 13 in Nature, could power soft robots or next-gen wearable and implantable tech.

    “It’s a very smart approach” to...

    New setup for image recognition AI lets a program think on its feet

    Artificial intelligence is getting some better perspective. Like a person who can read someone else’s penmanship without studying lots of handwriting samples, next-gen image recognition AI can more easily identify familiar sights in new situations.

    Made from a new type of virtual building block called capsules, these programs may cut down the enormous amount of data needed to train...

    New 3-D printed materials harness the power of bacteria

    A new type of 3-D printing ink has a special ingredient: live bacteria.

    Materials made with this “living ink” could help clean up environmental pollution, harvest energy via photosynthesis or help make medical supplies, researchers report online December 1 in Science Advances.

    This study “shows for the first time that 3-D printed bacteria can make useful materials,” says Anne Meyer...

    Actress Hedy Lamarr laid the groundwork for some of today’s wireless tech

    Once billed as “the most beautiful woman in the world,” actress Hedy Lamarr is often remembered for Golden Age Hollywood hits like Samson and Delilah. But Lamarr was gifted with more than just a face for film; she had a mind for science.

    A new documentary, Bombshell: The Hedy Lamarr Story, spotlights Lamarr’s lesser-known legacy as an inventor. The film explores how the pretty veneer...

    When it comes to self-driving cars, what’s safe enough?

    Self-driving vehicles passed a major milestone in November when Waymo’s minivans hit the streets of Phoenix without backup human drivers — reportedly making them the first fleet of fully autonomous cars on public roadways. Over the next few months, people will get a chance to take these streetwise vehicles for a free spin as the company tries to drum up excitement — and a customer base — for...

    This material does weird things under pressure

    View the video

    A newly fabricated material does more than just hold up under pressure. Unlike many ordinary objects that shrink when squeezed, the metamaterial — a synthetic structure designed to exhibit properties not typically found in natural materials — expands at higher pressures.

    This counterintuitive material is made up of a grid of hollow 3-D crosses — shaped like six-way...

    Fluorescence could help diagnose sick corals

    Sickness makes some corals lose their glow.

    Disease reduces a coral’s overall fluorescence even before any sign of the infection is visible to the naked eye, a new study finds. An imaging technique that illuminates the change could help with efforts to better monitor coral health, researchers report November 6 in Scientific Reports.

    Many corals naturally produce fluorescent...

  • 50 years ago, artificial limbs weren’t nearly as responsive

    Electric limbs

    Very subtle control of artificial limbs by means of a tiny electronic device may become possible.… [The] electronic device … [is] designed to be injected into a muscle through a thick hypodermic needle. A tiny package strapped to the outside of the limb will beam radio waves at the device, which will return them, modified by the electric current produced in the muscle. — ...

    Artificial insulin-releasing cells may make it easier to manage diabetes

    Artificial cells made from scratch in the lab could one day offer a more effective, patient-friendly diabetes treatment.

    Diabetes, which affects more than 400 million people around the world, is characterized by the loss or dysfunction of insulin-making beta cells in the pancreas. For the first time researchers have created synthetic cells that mimic how natural beta cells sense blood...

    Leafhoppers use tiny light-absorbing balls to conceal their eggs

    Nature has no shortage of animal camouflage tricks. One newly recognized form of deception, used by plant-eating insects called leafhoppers, was thought to have a whole different purpose.

    Leafhoppers are found worldwide in temperate and tropical regions. Most of the insects, of which there are about 20,000 described species, produce small quantities of microspheres called brochosomes —...
