The ability to read other people is largely perceived to be intuitive--some people just have a talent for “seeing” what other people are thinking or feeling. But what if you could augment yourself with such an ability, allowing you to perceive changes in other people’s biologies as their biochemical state changes? A company called 2AI Labs has developed a pair of glasses--known as O2Amps--that supposedly can do just that.
Like a coin machine sorting change according to size, a new lab-on-a-chip can sift cells according to their weight and other properties. Doctors could use it to tease out biological matter from the bloodstream and detect cancer or potentially other ailments.
The Ebola virus—one of the world's deadliest diseases—has a kill rate of 90 percent. That's largely because the best current treatment must be applied within one hour of infection. Which is an almost impossibly brief window, considering symptoms may take anywhere from two to 21 days to appear in humans. But a new treatment has shown success in curing the disease when administered 24 hours or more after infection—at least when tested in monkeys.
The short answer: yes, it’s possible to go blind from drinking moonshine. But it’s also possible to go blind staring at the sun. When consuming alcoholic beverages of the DIY variety, the important thing is to let common sense be your guide.
While serving as an army medic during Operation Desert Storm, Richard Schwartz became all too familiar with gunshot wounds, particularly shots to the pelvis and upper legs. Enemies would target that region because body armor doesn’t always cover it. Conventional tourniquets don’t work around the abdomen—it’s impossible to tie them tight enough to cut off blood flow from the aorta. Soldiers with “junctional hemorrhages” may have only a few minutes before they bleed to death.
Think a trip to the pharmacy is overwhelming? Try this: One million billion billion billion billion billion billion. That’s a 1 with 60 zeroes after it. That’s the number of potential new medicines that could still be made, according to a new study. It may be more than the number of stars in the universe.

Only under special circumstances. “I mean, it doesn’t just happen to any Joe Schmo walking down the street holding his urine too long,” says Scott Eggener, a urologist at the University of Chicago. “But for someone who has had major surgery or cancer or had radiation in his bladder, or whose bladder had been removed and we make them a new bladder out of intestine, then yes—those are situations where the bladder can rupture.”
An ounce of prevention is worth a pound of cure, the saying goes, and a new algorithm will test that formula by predicting what will be wrong with a patient in the future, based on his or her past — and that of everyone else.
The human body isn't a metal machine, but it's still plenty complicated, and regulating it like a machine is tough to pull off. That's why a new discovery by Klas Tybrandt, a doctoral student in Organic Electronics at Linköping University, Sweden, is exciting: he's developed the first integrated chemical chip, similar to silicon-based electronics, but for biologic material.
We've seen snake robots and, of course, tons of surgery robots (including the weird lamprey-bot), but Dr. Michael Argenziano, the Chief of Adult Cardiac Surgery at New York-Presbyterian Hospital and Columbia University Medical Center in New York, says we'll soon have fully untethered snake-type robots that will crawl through the human body, assisting with all kinds of fixes and maintenance.
Scientists are getting another chance to get inside Phineas Gage’s head. The 25-year-old Gage was a railroad supervisor back in 1848, using a 13-pound, 3-foot-7 iron rod to pack blasting powder into a rock just moments before becoming history’s most interesting neuroscience case. Gage somehow triggered an explosion that drove the rod straight through his left cheek and out the top of his head, taking a chunk of his left frontal lobe with it.
It’s no cure, but it could mark a significant victory in the fight against HIV. A 17-member advisory panel for the Food and Drug Administration has endorsed an over-the-counter HIV test that would allow consumers to test themselves for the AIDS-causing virus in the privacy of their own homes in just 20 minutes.
Reddit’s IAmA forums can be a regular source of BS, so when we came across this “Ask Me Anything” session in which a 24-year-old electrical engineer (and grad student) shares his experiences with having magnets implanted in his fingertips, we were skeptical. Then we read it, and it was kind of awesome. Moreover, it appears there are lots of people out there interested in the magnetic implant subculture--which apparently is a real thing.
Some seizures briefly incapacitate, while other seizures can be deadly. Knowing the difference is obviously of grave importance, but figuring out which is which is difficult. So a team of MIT Media Lab researchers have developed a wristband that can tell the difference between the more benign breed of seizure and the one that might kill you, and may even be able to predict seizures before they strike.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
