Glowing antibacterial bandage sheds light on infected wounds

Bandaged wounds need to be checked for infection, yet removing the bandage to check the wound can delay its healing. Australian scientists may have a fix for this paradox, in the form of a dressing that glows if the wound is infected.

MIT SensiCut tech identifies materials for laser-cutting

In a busy workshop, it's possible to lose track of what substance a given sheet of material is composed of – making it risky to cut with a laser. SensiCut is designed to help, by identifying 30 different materials based on their surface qualities.

Wearable device detects a wider-than-ever range of airborne toxins

While wearable sensors can detect airborne toxins in the user's environment, any one device can usually only identify a few such substances. A potentially much more useful new sensor, however, can reportedly detect over 100 at once.

The future of prosthetic limb control may be magnetic

Currently, most powered prosthetic limbs are controlled by electrodes in the user's residual stump. An experimental new MIT system, however, is claimed to work better by replacing those electrodes with implanted magnetic beads.

“Intestinal bandage” designed to better heal digestive tract wounds

When it comes to closing incisions or other wounds in the digestive tract, sutures alone aren't enough to keep fluids or food waste from leaking out into the abdomen. A new hydrogel patch is designed to help, by thoroughly sealing such injuries up.

Strange supersolid state of matter created in new dimension

There are many exotic states of matter besides the basics of solid, liquid, gas and plasma. One of these, known as a supersolid, was confirmed a few years ago, and now University of Innsbruck scientists have created it in a new two-dimensional form.
