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

When HapiFork first debuted at the Consumer Electronics Show in January, the brightly-colored, vibrating fork caused a stir, landing press coverage from all over the world, including a mention on The Colbert Report.

Basically, the fork vibrates if you eat too fast. Some folks thought the fork served a useful purpose -- getting users to eat more slowly -- while others thought it was just a novelty. It is a vibrating utensil, after all.

The folks at Hapilabs, the company behind HapiFork, say they're just glad people are talking about the fork at all because that means there's … Read more

Postpartum depression afflicts between 10 percent and 15 percent of new moms. But with some never seeking help, those numbers may be even higher. And in a new study out of Case Western Reserve, researchers found that many women don't seek counseling because of the stigma attached to depression and because they feel they simply don't have the time -- but they would go online for help if professionals were available and they could remain anonymous.

"Mothers cannot always find a sitter and then spend time driving to and from counseling," Judith Maloni, lead investigator and … Read more

No diversion can divert me from the fact that treadmills are boring. Even if the weather is bad, I'm not much of a TV viewer -- on or off the treadmill. And I often find the most energizing music to also be the most annoying. Reading on a treadmill can be downright nauseating.

But thanks to an experimental system out of Purdue University, I soon may be able to catch up on my backlog of New Yorker digital issues while clocking time on the dreaded tread.… Read more

There just aren't enough donated organs to fill the need. That's why scientists have been dreaming of growing transplantable organs in labs. Scientists at the Massachusetts General Hospital Center for Regenerative Medicine have made a step forward by creating a functional rat kidney.

The process is not quite as futuristic as growing a whole organ from scratch. Researchers started with kidneys from dead rats and used a special soap-cleaning process to scrub away the cells. Essentially, this gave them a foundation of a kidney to work with, a blank canvas.… Read more

It's hard to imagine life without a limb -- not just the physical difficulties, but how it might affect your relationship with your body, and your sense of how you're perceived by the world around you. One prosthetist is taking into account not just restoring limb function, but also the wearer's personality and style.

The Alternative Limb Project is the work of Sophie de Oliveira Barata, who, taking her honors degree from the London Arts University studying special-effects prosthetics, went to work as a sculptor for a prosthetics company. In her eight years there, she created realistic limbs and digits for amputees who wanted their new limbs to blend into their bodies.

de Oliveira Barata has continued this work with the Alternative Limb Project, and her realistic limbs, molded from casts of the customer's own body, are incredibly detailed. But some people prefer to stand out in a crowd. … Read more

In a quest to learn what leads some people to turn to Facebook to connect with others, doctoral student Russell Clayton of the Missouri School of Journalism found that anxiety and alcohol use seem to play a big role.

For his master's thesis, which appears in the May issue of Computers in Human Behavior, Clayton surveyed more than 225 college freshman about two emotions, anxiety and loneliness, and two behaviors, alcohol and marijuana use. He found that the students who reported both higher levels of anxiety and greater alcohol use also appeared the most emotionally connected with Facebook. Those … Read more

Pain has long been thought to be at least somewhat subjective, making it difficult to measure consistently from one person to the next. But in a new study out of the University of Colorado at Boulder, healthy volunteers subjected to a dose of intense heat all experienced a consistent pattern of neurological activity that scientists captured on function MRI, which tracks blood flow through the brain.

While this doesn't mean that people experience pain in exactly the same way, the findings -- published today in the New England Journal of Medicine -- suggest that there may be a better … Read more

Studying the brain can be a tricky business.

The interesting stuff, such as neurons and how they communicate, is obscured by things like fatty tissue. Usually, scientists just cut it up into paper-thin slices to study, like with Einstein's brain, but a team of scientists at Stanford University, led by Karl Deisseroth and Kwanghun Chung, have found what the director of the National Institute of Mental Health Thomas Insel is calling "one of the most important advances for doing neuroanatomy in decades."

The new technique lets researchers leave the brain intact, which puts an end to the damage that slicing can cause. It involves infusing the brain with acrylamide, which binds the proteins; once heated, it polymerizes, preserving the important molecules. Then, the brain is rinsed with sodium dodecyl sulfate (SDS) detergent, which strips the fatty lipids, leaving intact the proteins that the researchers wish to study. … Read more
