Medical detectives National Institutes of Health have just cracked their first case wide open, a result they hope to repeat with a slew of other uncharacterized illnesses and conditions. The Undiagnosed Diseases Program (UDP), a sleuthing agency set up within the NIH in 2008 to connect the dots between cases of undiagnosable illnesses, has traced the source of an extremely rare vascular disorder back to its genetic roots, notching the first closed case for the UDP and another victory for diagnosis genomics.
With telepresence robots serving as stand-ins, there’s no reason for sick kids to miss school. Some children may prefer to skip class, of course, but for those with serious immune system disorders, telepresence ‘bots are a lifeline to the outside world.
Yeah, you've been thinking about getting that thing checked out, but it's just a mole right? Such is the problem with melanoma; it's tough to know which spots on the skin are benign and which could be the hallmark of early-stage skin cancer.
For people with memory-degrading conditions like Alzheimer’s, it’s not always easy, or even possible, to remember to take one’s medicine. Yet forgetting to take your meds—or perhaps worse, forgetting that you already took them and doubling up—can derail a dosage schedule and in worse cases be detrimental to your health. So a couple of University of Texas students have come up with a smart digital system that helps the forgetful among us remember to pop our pills and verifies visually that we’ve done so.
Purdue University researchers have built a chip-sized replica of a portion of the human female breast, and aim to use it to study nanoparticles for detection and targeting of tumor cells. The "breast on a chip" is the first step in studying the mammary ducts from the inside, which could help doctors diagnose and treat the disease in its earliest stages, researchers say.
Faced with a diminished drug-development pipeline in the private sector, the Obama administration is starting a federal drug development center, aiming to spur the creation of new medicines.
The new National Center for Advancing Translational Sciences will get $1 billion in funding to conduct drug research with the goal of attracting private investors.
Embedding minuscule glass tubes inside a mouse brain allows neuroscientists to monitor brain activity over long periods of time, watching neurons and tissue change with illness or aging. The method, developed at Stanford University, opens a porthole into the brain's deepest recesses.

The obvious concern is that city sidewalks are dirty. And that’s a valid concern, says Daniel Howell, a biologist at Liberty University in Virginia who has lived mainly shoeless for the past few years. “There’s a lot of soot, so your feet get blacker than if you were in the woods,” explains Howell, who has toured New York barefoot several times. But, he says, a little soot isn’t bad.
