What Your Poop Is Trying to Tell You

What the hell is that? Seriously, did that just come out of you or did it crawl up the pipe? If you've just exorcised a poo that looks nothing like what you've eaten recently, it could be a sign of a serious illness. It could also just be that curry from last Wednesday, so it's good to know what to look for. » 4/22/14 3:20pm Yesterday 3:20pm

Scientists Have Cloned Embryos From Adult Cells For the First Time Ever

Ever since Dolly the sheep was cloned eighteen years ago, scientists have been trying and failing to use that same technique to create cloned human embryos from adult cells. Now, they've finally succeeded, in what could a major step toward personalized organ transplants and other therapies that rely on a pool of stem… » 4/18/14 3:24pm Friday 3:24pm

A 3D-Printed Ultrasound Cast That Looks Awesome and Heals You Faster

Old-fashioned casts are nasty, a festering stinksleeves that you wear like a medieval torture device for what seems like forever. 3D-printed casts take care of the smell and itch issues, and now Deniz Karasahin has designed the next step: a custom cast with an ultrasound device to speed up bone healing. » 4/18/14 12:40pm Friday 12:40pm

This Bionic Ankle Walks Like It's Alive

The human lower leg is a marvel of biological engineering—it lets you have a long, strong stride while minimizing exertion and joint strain. But conventional spring and hydraulically-driven prosthesis worn by amputees offer no such benefit and can cause osteoarthritis-inducing skeletal strains. The BiOM T2 system aims… » 4/18/14 11:40am Friday 11:40am

A Rare Genetic Mutation in These Siblings Makes Them Immune to Viruses

Viruses are incompetent but smart little things. Unable to make proteins on their own, they hijack ours for their own nefarious purposes. But what if we gave the viruses broken proteins? An incredibly rare genetic disorder in a brother and sister pair does exactly that, making them immune to many classes of viruses—and … » 4/15/14 4:40pm 4/15/14 4:40pm

British Scientists Say They've Created Artificial Blood for Humans

Somebody ring the bell at the blood factory, because it's almost time to get those assembly lines running. Almost. A team of British scientists say they've created red blood cells suitable for transfusion into humans, a breakthrough that could change the lives of millions—if it works. » 4/14/14 1:20pm 4/14/14 1:20pm

Tracking an Ebola Outbreak in a City Without Maps

If you Google Map Guéckédou, the Guinean city smack dab in the Ebola virus's deadly domain right now, you'd see just an abstract blotch of beige and yellow. Zoom all the way in on satellite view, and you can barely make out the outlines of buildings. Don't even think about trying Street View. Google Maps simply reflects… » 4/11/14 10:00am 4/11/14 10:00am

Doctors Can Now Grow Engineered Vaginas in Women

After decades of work, a team of doctors say they've successfully engineered vaginas that have been implanted and grown in women. The vaginas were grown in a lab from the female patients' own cells and later transferred to their bodies, where they formed into normal vaginas. The breakthrough bears some huge… » 4/10/14 7:13pm 4/10/14 7:13pm

Scientists Manipulate Genes to Make Old Organs Young Again (in Mice)

Researchers at the University of Edinburgh showed this week that they could teach an old mouse's thymus to bounce back to a healthy, youthful state, simply by manipulating a single protein that controls gene expression. It's the first time scientists have been able to regenerate a living organ by gene manipulation, and … » 4/10/14 10:10am 4/10/14 10:10am

Could Google Glass Really Help People with Parkinson's?

While the world has been squabbling about Glassholes, doctors have quietly been testing the potential of Google Glass in medicine. Features that may seem silly to use in a cafe or on the subway have real advantages in the doctor's office. Hand-free control? Remote diagnosis? On-demand medical records? Check check… » 4/09/14 4:40pm 4/09/14 4:40pm

How These Microscopic Diamonds Are Going to Shape the Future

No doubt you're already familiar with the many ways graphene promises to save us all, but there's another (so-called) miracle material out there vying for your attention—and it's sparkly, to boot. Say hello to the latest and greatest substance to kick science's ass straight into the future: the nanodiamond. » 4/09/14 10:00am 4/09/14 10:00am

Is It a Good Idea to Vaporize and Inhale Alcohol?

Vaporizing, and then inhaling alcohol has gained a lot of attention lately. In the 1950s it was introduced as a treatment for excessive fluid in your lungs, called pulmonary edema. It's now gained popularity as a way to quickly become intoxicated. Proponents of this process-to-become-plastered, tout several benefits… » 4/09/14 7:30am 4/09/14 7:30am
