Heartbeat of a Dying Star - Space.com In
a stellar version of the walking dead, one near-corpse of a star
jumpstarts the heartbeat of its close companion as the two spiral toward
an eventual embrace that will destroy them both. One of the stars
spins on its axis hundreds of times every second, the other rotates once
every 2.8 seconds. They dance around one another every 2.4 hours,
travelling at a remarkably swift 0.1 percent of the speed of light.
teeth 'could soon be grown'
- BBC Scientists
at King's College London have been awarded £500,000 to help them
develop human teeth from stem cells. The company Odontis, set up by
the college, hopes to develop its research for tests on humans within
two years after successful research on mice. Stem cells, the
so-called master cells, would be programmed to develop into teeth and
then transplanted into the patient's jaw where the gap is. The cost
should not be more than the price of synthetic implants of between £1,500
- £2,000. But it could be five years before the technology is widely
available to the general public.
minds: Is mind control just the stuff of movies - or can it be real?
- BBC American
neuroscientists are currently developing "memory-management"
drugs. They believe that such pills could help individuals improve their
memory skills or even erase unwanted memories, such as that bad
childhood experience lurking at the back of your mind. So is mind
control myth or reality? "'Mind control' is a made-up term",
says Professor E Mark Stern of Iona Collage in New York, author of The
Other Side of the Couch. "But yes, it is possible to totally
influence a person's inner world."
