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)
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
