Britain Gives Nod for
Animal-human Hybrid Embryos
by Tim Castle, ABC News
LONDON, May 17 (Reuters) - Britain on
Thursday cleared the way for scientists to conduct experiments using
hybrid animal-human embryos after the government bowed to protests
from researchers who said a proposed ban could hurt their work.
Scientists want to use the hybrid
embryos to find cures for illnesses such as Parkinson's, stroke and
Alzheimer's...

Is This REALLY Proof
That Man Can See into the Future?
by Ker Than, Space.com
Do some of us avoid tragedy by foreseeing it? Some scientists
nowbelieve that the brain really CAN predict events before they
happen
Professor
Dick Bierman sits hunched over his computer in a darkened room. The
gentle whirring of machinery can be heard faintly in the background.
He smiles
and presses a grubby-looking red button.
In the
next room, a patient slips slowly inside a hospital brain scanner.
If it wasn't for the strange smiles and grimaces that flicker across
the woman's face, you could be forgiven for thinking this was just a
normal health check.
But this
scanner is engaged in one of the most profound paranormal
experiments of all time, one that may well prove whether or not it
is possible to predict the future...

Envision This: Mathematicians
Design Invisible Tunnel
Electromagnetic "wormhole" results from turning invisible sphere
inside out
by J.R. Minkel, Scientific American
Call it
Harry Potter's invisible sleeve. New calculations show how to make
an electromagnetic "wormhole"—a tube that is invisible from the
sides, allowing light to shine down the center unseen [see
endnote].
The
concept is a twist on a spherical cloak of invisibility proposed
last year. Such a device would be made of metamaterial, a thicket of
metal rings or other shapes that bends light in funny ways. A hollow
shell of metamaterial could in principle channel a single frequency
of light around its inner space without slowing the light down,
rendering that hidey-hole invisible to the outside world at that
frequency.
But the
invisibility cuts both ways. If light does not enter, then whatever
is in the cloak cannot see outside, says mathematician Allan
Greenleaf of the University of Rochester.
So
Greenleaf turned the cloak inside out...

"Hot Ice" Planet
Discovered, Covered in "Solid Water," Experts Say
by John Roach, National Geographic
News
A Neptune-size planet likely covered
in hot—but solid—water has been discovered in a snug orbit around a
nearby star, a team of astronomers announced today.
While this planet is not fit for life,
the finding suggests astronomers may soon detect habitable planets
in similar alien solar systems, said Michaël Gillon of the
University of Liège in Belgium.
"We are just at the door of a very
exciting era," he said in an email interview.
The exotic water detected on the
planet is known to form under extremely high pressure—conditions
that can only be replicated on Earth in laboratories...
