When Captain Kirk stepped out with a tricorder in hand in Star Trek in 1966, the data sensing, scanning and analyzing gadget seemed a rather useful but far-in-the-future piece of technology. With the Swift Ray 1, we're a step closer to its reality.

It's ironic that in order to see how a wound is healing, the dressing has to be removed, potentially setting back the healing process. A clever new bandage, however, continuously shows how the wound is faring – without needing a power source.
-
Leaking sutures after abdominal surgery are a potentially life-threatening complication that surgeons might not pick up immediately. Researchers have developed a hydrogel patch that can rapidly detects postop leaks at suture sites inside the abdomen.
-
It's a sad fact that burn victims often feel a great deal of pain when the dressings on their wounds are removed. A new hydrogel-based dressing could change that, however, as it easily releases from the skin when cooled.
-
Most wound dressings simply cover the injury and perhaps also kill harmful bacteria. The PAINT system goes much further, as it incorporates a pen that could one day allow doctors to paint a gelatinous healing ink right into wounds.
-
Researchers have confirmed what Indigenous Australians already knew: native plants have great healing properties. Two plants have been found to heal wounds quickly and efficiently, paving the way for the use of more plant-based therapeutic treatments.
-
Starting with fibers taken from pig tissue, researchers developed dissolving sutures that can be loaded with molecular sensors or medication. The hope is that they could speed healing and/or alert doctors when something is wrong at a surgical site.
-
For some time now, it has been known that wounds with a zig-zag pattern heal faster than those which form a straight line. Scientists have now determined why this is so, and their findings could change the ways in which surgical incisions are made.
-
Indian scientists have developed a groundbreaking method to extract keratin and melanin from discarded hair, opening up possibilities for their use in wound dressings and sunscreens.
-
In diabetics, wounds tend to progress quickly and heal slowly. Researchers have used electricity to heal diabetic wounds three times faster, which offers great potential for treating those with diseases that lead to reduced wound healing.
-
MIT scientists have developed a synthetic system that can stem internal bleeding, to help save lives after a traumatic injury. Two components come together at a wound to form a clot, without doing so elsewhere in the body where it might be dangerous.
-
It's ironic that in order to check if a wound is becoming infected, doctors may end up setting back the healing process by removing the dressing. An experimental new dressing is designed to help, as it changes color if an infection is occurring.
