Above, your moment of science zen for the weekend.
Using an innovative application of stem cells, researchers at the Tokyo University of Science have regenerated hair on a bald mouse. Their accomplishment is described as a breakthrough, and inspires hopes of an alternative to hair transplants for bald guys who rely on toupees and comb-overs (or as they're known in Japan, "bar codes"). From a blog post at the Wall Street Journal, by Eleanor Warnock:
After cultivating two different kinds of cells taken from hair follicles in mice, the team transplanted the cells into the hair follicles of a bald mouse. Within three weeks, 74% of the hair follicles implanted with the cells grew back hair. The new hair connected with nerves and surrounding tissues showing that the follicles had become fully functional and were able to regrow hair even after hair was pulled out.
The scientists were also able to play around with the density and color of the hair by changing the type of cells they transplanted into the mouse’s hair follicles. When they used cells from a human hair follicle, a human hair grew.
The results were published this week in the online journal Nature Communications. Jokes aside, the focus isn't so much male premature baldness, but helping people who have lost hair due to injury or disease. Not because premature baldness isn't a problem worth addressing, but because the technique at work here would be tough to apply for larger areas of hair growth. (thanks, @steppinlazer)
Apple released this lovely new commercial featuring Carl Sagan reading from his magnificent 1994 book Pale Blue Dot: A Vision of the Human Future in Space, now available as an audiobook. This surprising partnership spurred Adweek to interview my friend Ann Druyan, Sagan’s wife, collaborator, and creative director of the Voyager Golden Record, about being […]
The Action Lab took a maglev gyroscope and placed it inside a sealed chamber to see what happens to a levitating gyroscope in a vacuum. A lot of people took issue with the experiment’s setup and explanation, but it’s interesting nonetheless. He responded to those concerns: Hi everyone! I see a lot of comments that […]

Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
