OK, it's not quite Dr. Crusher's dermal regenerator (seen above), but Arizona State University researchers have demonstrated a laser system for sealing wounds. The system involves a sealing paste -- made from silk protein mixed with gold nanorods -- that bonds with skin when heated with a laser. From IEEE Spectrum:
To use a laser to seal skin, one must focus the heat of the light using some sort of photoconverter. (Chemical engineer Caushal) Rege’s lab opted for gold nanorods and embedded them in a silk protein matrix purified from silkworm cocoons. A silk protein called fibroin binds to collagen, the structural protein that holds together human skin cells. When near-infrared light hits the gold nanorods, they produce heat and activate the silk and skin to create bonds, forming a sturdy seal...
They are currently watching how the laser-activated seals hold up in living rats. If that goes well, they’ll move to pigs, and perhaps eventually, humans.
As you may have noticed, a number of bird species have proven capable of mimicking snippets of sound they overhear, be it a melody, the wail of an ambulance or a dirty phrase taught to them by some drunk fella at a party. But here’s the thing: most mammals suck at it. Not so seals. […]
In the New York Times, Kenneth Chang reports that NASA’s Curiosity rover on Mars has detected high amounts of methane, a gas that is commonly a signature of life. From the NYT: “Given this surprising result, we’ve reorganized the weekend to run a follow-up experiment,” Ashwin R. Vasavada, the project scientist for the mission, wrote […]
As part of research on how to make better prosthetic legs, Vanderbilt University engineers put people on a treadmill and made them stumble. Over and over. By better understanding peoples’ stumble reflex, they hope to improve the computer-controlled stumble response in prosthetics. But to learn how people catch themselves, they had to trip them first. […]
So you’ve visited the Kennedy Space Center every year. You’ve watched “The Right Stuff” for the 95th time. There must be something to do while you’re waiting to join Space Force for the next manned mission to Mars or the moon. Here’s a combo that should raise a salute from any fan of space or […]
Looking for a new tablet? If you haven’t upgraded in a while, it might be time to check out the latest iPad Pro for two very good reasons. First, the 2018 model is a real workhorse. The 12X Bionic chip processor means it can handle any task you set out for it, and still have […]
You want wireless earbuds to make an impact on your mood and workout, not the environment. If that’s the case, we’ve got a new contender for AirPod market share: Brio Phantom X7 True Wireless Earbuds. The features on these tiny, comfortable buds are impressive even without the environmental angle. Their Bluetooth 5.0 connectivity is good […]
