Surprising variation in human genes
Newsday http://www.newsday.com/news/health/ny-hsdna233903749jul23,0,5818796.story?coll=ny-health-headlines
*************************
Healthy people possess surprising
variations in the number of copies
of specific genes, an unexpected
finding that Cold Spring Harbor
researchers say may contribute to
human diversity and may someday help
identify genes involved in certain
diseases. The researchers found that
many people are missing large chunks
of DNA, while others have extra...

When Technology Imitates Art
New York Times July 22, 2004
*************************
With the aid of scanners and
software, computer-guided milling
machines can precisely duplicate
sculptures and other art objects,
blurring the line between what is
authentic and what is...

UCLA Scientists Control a Single
Electron's Spin With Commercial
Transitor
KurzweilAI.net July 22, 2004
*************************
A UCLA team succeeded in flipping a
single electron spin upside down in
an ordinary commercial integrated
circut chip for the first time, and
in detecting that the current
changes when the electron flips.
"Our research demonstrates that an
ordinary transistor can be adapted
for practical quantum computing,"
said UCLA professor of physics Hong...

For Doctored Photos, a New Flavor
of Digital Truth Serum
New York Times July 22, 2004
*************************
Dartmouth College computer
scientist Hany Farid has developed
algorithms that detect photographs
that have been digitally tweaked by
combining and editing images. The
technique uses "nearest-neighbor"
and other techniques to detect
alterations. "Digital watermarking"
(embedding identifying pixels in an
digital photo), a technique to...

Gold charges up electron by
electron
Nature Science Update July 22, 2004
*************************
IBM scientists have succeeded in
changing the electrical charge of
individual atoms. They used a
scanning tunnelling microscope (STM)
to deliver a single electron to
individual gold atoms. The STM can
also go back over the gold atoms and
sense whether they are neutral or
negatively charged. A string of
neutral and negative gold atoms
could...
