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)
Tomorrow the final hammer goes down on an archive of original Nikola Tesla patents, lightbulb design drawings by Thomas Edison, a World War II Enigma Machine, Stephen Hawking’s personal Simpsons figure, and many other science-related curiosities in Christie’s “Eureka!” auction.
Every year, hundreds of thousands of horseshoe crabs, a threatened species, are “milked” for up to 30% of their blood that’s used to test new medical drugs, including possible COVID-19 vaccines, for bacterial contamination. The animals are eventually released but, surprise, a large percentage of them die. Revive & Restore, the wildlife conservation organization most […]
Exploding Head Syndrome (EHS) is an actual medical condition in which an individual sometimes experiences an explosive sound inside their head when drifting off to sleep or just waking up. The big boom may also be accompanied by a flash of light. Also called “episodic cranial sensory shock,” cases have been reported in the medical […]

We all know vital information about ourselves and our private digital accounts can be compromised by cybercriminals. However, many would be frightened to know just how compromised they and their vital data are right this moment. Security researchers Digital Shadows say usernames and passwords for more than 15 billion accounts are currently up for purchase […]
While mosquitoes have certainly earned their title as the deadliest animal on earth, their impact on most of our lives is usually a lot less consequential. But even though they might not transmit a disease to you or seriously affect your life, being a blood donor for one of those insects is certainly an annoyance. […]
