Who will wake up from a coma? Electrical jolts in the brain offer hints

Researchers may have found a way to detect inklings of consciousness in comatose and vegetative patients just days after they experience a brain injury—and it appears the method may help predict which patients will rouse and recover in the months afterward.

A team of researchers in New York recorded electrical activity in the brains of unresponsive patients while giving them simple spoken commands, such as “keep opening and closing your right hand” or “wiggle your toes.” Of 104 unresponsive patients tested, 16 (15%) showed some activity. Of those 16 patients, eight of them (50%) went on to be able to follow spoken commands by the time they left the hospital. A year later, seven of them (44%) were able to function independently for at least eight hours at a time.

In contrast, only 14% of those who showed no electrical activity early on reached that level of recovery after a year. The results were published this week in the New England Journal of Medicine.

Easy-to-make thermal chameleon fades into the background

Chameleons, unlike bowties, are cool. The chameleon is most famous for its ability to blend with its surroundings (I'm just as impressed with the acrobatic tongue), something we'd often like to do ourselves. Doing something similar with heat would be exciting. Imagine a camouflage suit that blended in with its background in both the visible and the infrared.

Three researchers suggest they've done exactly that in a recent paper on a thermal cloaking demonstration. Unfortunately, their cloak doesn't so much blend with the surroundings as become completely transparent. This is still remarkable, and, at least when cloaking in two dimensions, it's surprisingly simple to make.

Hiding in plain sight

Before we get to how the cloak works, let me take you through what the thermal chameleon is trying to hide. Let's imagine that I have a long cylinder. At one end, I heat the cylinder to 50°; and at the other end, I cool it to 10°. If I measure the temperature along the length of the cylinder, it will decrease steadily between the hot end and the cold end.
