    This stretchy implant could help kids avoid repeated open-heart surgeries

    A new stretchy prosthetic could reduce the number of surgeries that children with leaking heart valves must undergo.

    The device, a horseshoe-shaped implant that wraps around the base of a heart valve to keep it from leaking, is described online October 10 in Nature Biomedical Engineering. In adults, a rigid ring is used, but it can’t be implanted in children because it would constrict...

    Watch this cuttlefish-inspired ‘skin’ morph into a 3-D shape

    View the video

    Now you see it, now you don’t.

    Inspired by cephalopods like octopuses and cuttlefish, which change their skin textures for camouflage, researchers fabricated a stretchy material that inflates into various 3-D shapes and flattens back out. These shape-shifting “skins,” described in the Oct. 13 Science, could someday help robots don quick disguises.

    Superbugs may meet their match in these nanoparticles

    Antibiotics may have a new teammate in the fight against drug-resistant infections.

    Researchers have engineered nanoparticles to produce chemicals that render bacteria more vulnerable to antibiotics. These quantum dots, described online October 4 in Science Advances, could help combat pathogens that have developed resistance to antibiotics (SN: 10/15/16, p. 11).

    The rise of respectful robots

    View the video

    A new robot has the mobility of R2-D2 and the manners of C-3PO.

    This knee-high, self-driving bot abides by social protocols as it weaves through foot traffic: keep right, pass left, respect others’ personal space. The machine, presented at the IEEE/RSJ International Conference on Intelligent Robots and Systems in Vancouver on September 25, paves the way for robots...

    New atomic clock is most precise yet

    A new model of atomic clock is now the world’s steadiest metronome, with a tick rate about six times more precise than the previous record-holder.

    This souped-up clock is an optical lattice — it measures time by counting the oscillations of light in a laser beam, which happen about 430 trillion times per second. Strontium atoms in the clock tick off each oscillation by absorbing and re-...

    M. Ehsan Hoque develops digital helpers that teach social skills

    M. Ehsan Hoque, 35Computer scientistUniversity of Rochester

    A growing band of digital characters that converse, read faces and track body language is helping humans to communicate better with one another. While virtual helpers that perform practical tasks, such as dealing with customer service issues, are becoming ubiquitous, computer scientist M. Ehsan Hoque is at the forefront of a more...

    Cool way to peer into molecules’ inner workings wins chemistry Nobel Prize

    An imaging technique that lets scientists capture 3-D views of proteins, viruses and other molecules at the atomic scale has won its developers the 2017 Nobel Prize in chemistry.

    Jacques Dubochet of the University of Lausanne in Switzerland, Joachim Frank of Columbia University and Richard Henderson of the MRC Laboratory of Molecular Biology in Cambridge will share the prize, the Royal...

    Origami outfits help these bots change tasks swiftly

    View the video

    Robots are taking “dress for success” to a whole other level.

    A new type of shape-shifting robot can undergo complete metamorphosis in a matter of minutes. The bot is composed of a simple metal cube that wraps itself in various high-tech origami sheets that fold into wings, wheels and other appendages for getting around. By donning and doffing different origami...

    Nature offers inspiration, and occasionally courage

    When Donald Griffin and Robert Galambos first reported that bats use the ricocheting echoes of sound waves to pilot through the environment, some scientists doubted it was possible. The team’s experiments, conducted in the late 1930s at Harvard University and reported in the early 1940s, coincided with World War II and the proliferation of active sonar systems for use on ships and submarines...

    Meet the first fleet of hive-minded robots.

    These robots can latch onto one another and link up their individual “nervous systems” — the network of connections between their computer processors, cameras, wheels and other gadgetry — to create a single-minded machine. The composite robots, reported online September 12 in Nature Communications, pave the way for a new...
