Adhesives for biomedical applications can be detached with light

    Summary
    Pulling off a little plastic bandage may soon get a lot less painful. Researchers have developed a new type of adhesive that can strongly adhere wet materials -- such as hydrogel and living tissue -- and be easily detached with a specific frequency of light. The adhesives could be used to attach and painlessly detach wound dressings, transdermal drug delivery devices, and wearable robotics.

    NASA’s GEDI Mission Will Track Carbon Emissions in Earth’s Forests

    Summary
    The Jedi in Star Wars is all about the force, but NASA’s GEDI is all about the forest. On December 5, the space agency launched their tree-tracking Global Ecosystem Dynamics Investigation (GEDI) instrument to the International Space Station (ISS), where it will use laser light to create 3D maps of Earth’s forests and estimate their carbon emissions. Unlike most mappers, GEDI is able to peer below tree canopies and see the vegetation that lies beneath — giving insight into carbon cycling,

    With Fruit Flies, Researchers are Gaining New Insights Into Autism

    Summary
    A telephone ringing. A car horn blaring. Fluorescent lighting overhead. These are everyday sights and sounds that most people don’t give a second thought to. But for a person with autism, being around ordinary sensory stimuli can be uncomfortable or even unbearable. Autism, typically thought of as a disorder affecting social functioning, can also have a profound effect on sensory processing. Although no two cases of autism are alike, it’s estimated that up to 90 percent of children and ad

    Juno's Mission to Jupiter Just Hit Its Halfway Point: What We've Learned So Far

    Summary

    In the Blink of an Eye, We're Turning Back the Climatic Clock by 50 Million Years

    Summary
    Absent serious action on climate change, we'll continue careening toward a climatic cliff. And modern civilization will be hard-pressed to survive the plunge. This is the essential take-away from new research probing Earth's climatic past to yield insights into our future. The research finds that if our emissions of carbon dioxide and other greenhouse gases continue unabated, Earth's climate will warm by the year 2150 to levels not seen since the largely ice-free Eocene Epoch about 50 mil

    Scientists Find What Makes Our Bones Strong When We Exercise

    Summary
    Exercise is good for us in a lot of ways. It helps cut the pounds, increases cardiovascular health, adds muscle mass and can boost our mood. What it also does, though, is help keep our bones strong. Studies have shown that regular exercise, especially involving weights, ups bone mass and maintains the health of our skeletal system. For us spring chickens, having strong bones might not sound all that critical, as our skeleton seems to get by just fine no matter what we do. But in the elder
