'House' episode helps doctor diagnose rare cobalt poisoning

When a patient in Germany stumped his doctors with a strange combination of severe symptoms including heart failure, vision and hearing loss, acid reflux, and enlarged lymph nodes, Dr. Juergen Schaefer was called in to lend his expertise. Turns out the doc isn't only gainfully employed solving medical mysteries at the Center for Undiagnosed Diseases just outside Frankfurt -- he's also a fan of the TV show "House."

Schaefer had recently seen and lectured about an episode in which the fictional Dr. Gregory House sees a patient with the same symptoms. In the episode, the fictional patient had been on the wrong end of a botched hip replacement and was suffering from cobalt poisoning. Schaefer told The Associated Press that, thanks to the show's well-researched script writing, "After five minutes, I knew what was wrong."… Read more

Snap cholesterol selfies with new smartphone app, device

New tech being developed at Cornell University aims to bring cholesterol testing to smartphones to make the numbers both more specific and easier to track.

Home cholesterol test kits have been around since the early 1990s, catering to those with high cholesterol levels -- which puts them at a higher risk of developing heart disease -- who need to check their numbers more than once every few years.

But the majority of home tests take total cholesterol readings only, without separating out the "good," high-density lipoprotein (HDL, which helps prevent cholesterol from building up in the arteries) from … Read more

Painless microneedle patch could test for TB

Today, one of the standard tests for tuberculosis involves inserting a hypodermic needle into a person's arm using a very precise angle and depth -- thereby requiring a certain level of skill on the part of the tester and chutzpah on the part of the patient.

Researchers at the University of Washington hope to replace this test with a painless, near-automated alternative -- a microneedle patch that they say is more precise and even biodegradable.… Read more

What's My Computer Doing?

At the end of a sweltering wedding season, many of us may be familiar with that drunken guest who falls asleep at dinner and is startled awake later, exclaiming "What's going on? Where am I? ... Where are the cookies?"

Those hazy, existential queries of the inappropriately inebriated aren't much different than the plaintive cries of modern PC users. Amid a shifting landscape of services, processes, modules, add-ons, plug-ins, drivers, BHOs, and DLLs--new Windows and Mac users trying to learn what the operating system is actually doing as their boxes suddenly whir can often feel overwhelmed. Here … Read more

A new way to predict breast cancer survival

A researcher who used to work in digital television has just led a team of Columbia University engineers to win the Sage Bionetworks / DREAM Breast Cancer Prognosis Challenge.

Dimitris Anastassiou, who is now a systems biologist (meaning he investigates interactions within biological systems), reports in the April 17 issue of Science Translational Medicine that his team's winning computation model is extremely predictive of breast cancer survival.

Before the challenge, Anastassiou and his team identified what they call "attractor metagenes," which are genetic signatures expressed in almost the exact same way across many types of cancer. Their new … Read more
