    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.

    Jennifer Dionne harnesses light to illuminate nano landscapes

    Jennifer Dionne, 35Materials scientistStanford University

    To choose her research goals, Jennifer Dionne envisions conversations with hypothetical grandchildren, 50 years down the line. What would she want to tell them she had accomplished? Then, to chart a path to that future, “I work backward to figure out what are the milestones en route,” she says.

    That long-term vision has led the 35-...

    Chong Liu one-ups plant photosynthesis

    Chong Liu, 30Inorganic chemistUCLA

    For Chong Liu, asking a scientific question is something like placing a bet: You throw all your energy into tackling a big and challenging problem with no guarantee of a reward. As a student, he bet that he could create a contraption that photosynthesizes like a leaf on a tree — but better. For the now 30-year-old chemist, the gamble is paying off.

    “He...

    Tiny ‘supraballs’ put a new spin on creating long-lasting color

    Tiny balls of melanin could someday paint the rainbow. They’re one of the key ingredients in a new way to craft a spectrum of structural colors — hues created when light interacts with special nanostructures.

    Structural colors are a longer-lasting alternative to chemical pigments, which lose all pizazz when they break down. Examples of durable hues abound in nature. For instance, many...

    Animal goo inspires better glue

    Finding a great glue is a sticky task — especially if you want it to attach to something as slick as the inside of the human body. Even the strongest human-made adhesives don’t work well on wet surfaces like tissues and organs. For surgeons closing internal incisions, that’s more than an annoyance. The right glue could hold wounds together as effectively as stitches and staples with less...

    New antennas are up to a hundredth the size of today’s devices

    Antennas just got a whole lot smaller.

    Tiny chips that communicate via radio waves are a tenth to a hundredth the length of current state-of-the-art compact antennas. At only a couple hundred micrometers across — comparable to the thickness of a piece of paper — these next-gen antennas can relay the same types of signals as those used by TVs, cell phones and radios, researchers report...

    Robot, heal thyself

    A new type of soft robot can go under the knife and make a full recovery in about a day.

    Researchers fashioned a robotic hand, gripper and muscle from self-healing rubbery material. To test their robots’ resilience, the engineers sliced each with a scalpel, then put them in an oven. After cranking up the heat to 80° Celsius, baking the bots for 40 minutes, then cooling them to room...

  • 50 years ago, steel got stronger and stretchier

    Ductile, strong steel

    Fundamental scientific knowledge of the behavior of metallic crystals has led to the design of a new series of alloy steels, stronger and tougher than those now available. The new alloys can be stretched from two to five times more than previous ones, yet also have high strength…. The alloys, called TRIP steels, are produced by [the process] Transformation Induced...

    Diamond joins the realm of 2-D thin films, study suggests

    Diamonds are going 2-D. The superhard form of carbon can be forged in thin films known as diamondene, new evidence suggests. While graphite, the form of carbon found in pencils, can be made into atom-thick sheets known as graphene, scientists have struggled to create two-dimensional films of its relative, diamond.

    When a pair of graphene sheets are squeezed to pressures around tens of...

    Slug slime inspires a new type of surgical glue

    View video

    For a glue that holds up inside the body, turn to the humble slug, Arion subfuscus. A new super-sticky material mimics slug slime’s ability to stick on slick wet surfaces and could lead to more effective medical adhesives.

    The material has two parts: a sticky layer that attaches to a surface, and a shock-absorbing layer that reduces strain. That makes the adhesive less...
