Researchers Build Logic Gates With RNA (Saturday 18th of October 2008 10:15:01 PM)
Ars Technica reports on fishing expedition* out of Cal Tech where scientists were able to
create logic gates out of RNA molecules. Thus far, they've demonstrated AND gates and OR gates,
with work proceeding on more labyrinthine systems. The work shows ...

(more)Scientists mimic molecules to protect against plague (Sunday 13th of July 2008 11:04:00 PM)
Germ that cause pneumonic plague can evade our first-line defences, making it laborious for the
body to fight infection. In fact, a signature of the plague is the lack of an inflammatory
response. Now, scientists have discovered a way to protect against ...

Hasu notes that scientists at the National prescript for Materials Science at Tsukuba in Japan
have created a device, consisting of 17 duroquinone molecules on a gold surface, that can in
theory encode 4.3 billion outcomes. The "device" does not constitute ...
(more)Similar DNA Molecules Able to Recognize Each Other (Monday 28th of January 2008 07:30:11 AM)
Chroniton brings us a story about fishing expedition* into DNA which has shown that
free-floating DNA strands are able to seek out similar strands without the assistance of other
chemicals. From Imperial College London: "The researchers observed the behaviour ...

An anonymous reader writes "A team led by the health center of Colorado at Boulder and the
health center of Milan has discovered some unexpected forms of liquid crystals of ultrashort
DNA molecules immersed in water, providing a new scenario for a key ...
(more)Scientists Offer 'Overwhelming' Evidence Terran Life Began in Space (Wednesday 15th of August 2007 07:10:03 AM)
An anonymous reader writes "Using data from recent comet-probing space missions, British
scientists are reporting today that the odds of life starting on Earth rather than inside a
comet are one trillion trillion (10 to the power of 24) to one against. ...
