Nail Stem Cells Are Highly Versatile

November 24, 2014 7:00 am | by USC Stem Cell | Comments

There are plenty of body parts that don’t grow back when you lose them. Nails are an exception, and a new study reveals some of the reasons why. A team of researchers has identified a new population of nail stem cells, which have the ability to either self-renew or undergo specialization or differentiation into multiple tissues.

Real-world Robotics Inspired Big Hero 6

November 17, 2014 8:25 am | by DARPA | Comments

The giant, balloon-like inflatable robot named Baymax in Disney’s Big Hero 6 has its roots in real-world research conducted by iRobot Corporation, Carnegie Mellon Univ. and Otherlab under DARPA’s Maximum Mobility Manipulation (M3) program. The film’s co-director said he was inspired to cast Baymax as an air-filled, soft robot after he saw an inflatable robotic arm on a visit to Carnegie Mellon’s Robotics Institute.

Supercomputers Enable High-res Climate Models

November 14, 2014 7:00 am | by Lawrence Berkeley National Laboratory | Comments

Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, a climate scientist was able to complete a run in just three months.

Sunspot is Back and Worse than Ever

November 13, 2014 7:00 am | by The Conversation, Paul Cally | Comments

The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger. Last month, the solar active region known as AR12192 entertained the world with the sunspot clearly visible to the naked eye as it produced a series of large flares. But, after spending some time over on the far side of the sun, it hasn’t finished impressing us yet.

Nanodaisies Can Kill Cancer

November 12, 2014 7:00 am | by North Carolina State Univ. | Comments

Researchers have developed a potential new weapon in the fight against cancer: a daisy-shaped drug carrier that’s many thousands of times smaller than the period at the end of this sentence. Once injected into the bloodstream, millions of these nanodaisies sneak inside cancer cells and release a cocktail of drugs to destroy them from within.
