    Pollution is endangering the future of astronomy

    OXON HILL, Md. — Even as technological advances allow astronomers to peer more deeply into the cosmos than ever before, new technologies also have the potential to create blinding pollution.

    Three sources of pollution — space debris, radio interference and light pollution — already are particularly worrisome. And the situation is getting worse. In the next two decades, as many as 20,000...

    A new gel could help in the fight against deadly, drug-resistant superbugs

    A new antibacterial ointment could help take down drug-resistant bacteria.

    In human skin samples and mice, the medicine completely cleared wounds of MRSA, the strain of Staphylococcus aureus that is resistant to methicillin and other antibiotics, and antibiotic-resistant Acinetobacter baumannii. Both microbes are known to cause serious infections in hospital patients. Researchers in the...

    Readers wrangle with definition of ‘species’

    Species shmecies

    In “Defining ‘species’ is a fuzzy art” (SN: 11/11/17, p. 22), Susan Milius asked scientists to define “species.” Schoolbooks may define the concept as a group of organisms that create fertile offspring when mating with each other but not when mating with outsiders. But for researchers specializing in the topic, a single definition is hard to come by.

    “It seems to me...

    New pill tracks gases through your gut

    Ingestible electronics are giving their first full tours of the gas in people’s guts.

    Newly constructed capsules, described online January 8 in Nature Electronics, sense various gases while traveling through a person’s digestive tract, revealing how the gut’s chemical composition reacts to factors like diet.

    What exactly each person’s gut gas could reveal about his or her health “...

    These disease-fighting bacteria produce echoes detectable by ultrasound

    Ultrasound can now track bacteria in the body like sonar detects submarines.

    For the first time, researchers have genetically modified microbes to form gas-filled pouches that scatter sound waves to produce ultrasound signals. When these bacteria are placed inside an animal, an ultrasound detector can pick up those signals and reveal the microbes’ location, much like sonar waves bouncing...

    Boy robot passes agility tests

    View the video

    Robots are on their way to passing gym class.

    The design of a new life-size bot named Kengoro closely resembles the anatomy of a teenage boy in body proportion, skeletal and muscular structure, and joint flexibility, researchers report online December 20 in Science Robotics. Compared with previous humanoid robots with more rigid, bulky bodies, Kengoro’s anatomically...

    AI has found an 8-planet system like ours in Kepler data

    Our solar system is no longer the sole record-holder for most known planets circling a star.

    An artificial intelligence algorithm sifted through data from the planet-hunting Kepler space telescope and discovered a previously overlooked planet orbiting Kepler 90 — making it the first star besides the sun known to host eight planets. This finding, announced in a NASA teleconference...

    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 December 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...
