It can take a village to save science -- a village that so far includes a Las Vegas music mogul, Kirkland rocket scientist, Port Townsend artist, Bothell chemist, Louisiana gas-and-oil man with a place in Port Angeles and a Savannah, Ga., computer programmer.
Russian computers controlling the International Space Station's (ISS) orientation and supply of oxygen and water have failed, Nasa officials say.
Biologists at the University of California, Riverside have identified the genes, and determined the DNA sequences, for two key proteins in the "dragline silk" of the black widow spider - an advance that may lead to a variety of new materials for industrial, medical and military uses.
A massive international study of the human genome has caused scientists to rethink some of the most basic concepts of cellular function. Genes, it turns out, may be relatively minor players in genetic processes that are far more subtle and complicated than previously imagined.
Among the critical findings: A huge amount of DNA long regarded as useless -- and dismissively labeled "junk DNA" -- now appears to be essential to the regulatory processes that control cells. Also, the regions of DNA lying between genes may be powerful triggers for diseases -- and may hold the key for potential cures.
The research, published in a set of papers in today's editions of the journals Nature and Genome Research, raised far more questions than it answered -- and in a sense was a rallying cry for more and deeper research into the functioning of the genome, often referred to as the "blueprint" for life.

Eastman Kodak Co. (NYSE:EK - news) said on Thursday it has developed digital camera technology that nearly eliminates the need for flash photography, part of the company's effort to make money from its deep patent portfolio.
The world's biggest maker of photographic film says its proprietary sensor technology significantly increases sensitivity to light. Image sensors act as a digital camera's eyes by converting light into an electric charge to begin the capture process.
Kodak, which is in the last year of a lengthy and expensive transformation into a digital photography company as its film business shrinks, intends to lean on its wealth of intellectual property to boost its bottom line, expecting up to $250 million this year alone in royalties and related revenues.
For example, Chief Executive Antonio Perez has previously said its new inkjet printer strategy grew out of the discovery of existing, unused patents for printer ink.
"Our strategy is to get it out of the lab and onto the street," said Chris McNiffe, general manager, Kodak Image Sensor Solutions.

An international team of astronomers with the Trans-atlantic Exoplanet Survey today announce the discovery of their third planet, TrES-3. The new planet was identified by astronomers looking for transiting planets - that is, planets that pass in front of their home star - using a network of small automated telescopes in Arizona, California, and the Canary Islands. TrES-3 was discovered in the constellation Hercules about 10 degrees west of Vega, the brightest star in the summer skies.
"TrES-3 is an unusual planet as it orbits its parent star in just 31 hours!," said Georgi Mandushev, Lowell Observatory astronomer. "That is to say, the year on this planet lasts less than one and a third days. It is also a very massive planet - about twice the mass of the solar system's biggest planet, Jupiter - and is one of the planets with the shortest known periods."

The international space station's newest power source, a set of solar wings, made its debut yesterday.
The solar array is part of a new 17.5-ton space station segment that was connected to the orbiting outpost during a spacewalk Monday.
The solar wings were deployed one at a time, first halfway unfurled and allowed to warm in the sun about 30 minutes. That prevented the solar panels from sticking together.
"We see a good deploy," astronaut James Reilly, who helped connect the new segment on Monday, said after the second wing was unfurled.

A 3000 lb "big bird" dinosaur called Gigantoraptor has got scientists into a flap.
The remains of the gigantic, surprisingly bird-like dinosaur - the biggest toothless dinosaur ever found - have been uncovered in the Gobi desert in Inner Mongolia, China, and challenge current understanding about the origins of birds.
The find was made when Chinese scientists were being filmed by a Japanese TV crew in Erlian Basin and they thought a nearby bone was an example of a newly discovered long necked dinosaur, called a sauropod.
But as they took a closer look, under the gaze of the camera, they at first thought it came from something like Tyrannosaurus rex, but then realised that they were gazing on a remarkable dinosaur that was new to science.
The animal - which lived in the Late Cretaceous- about 85 million years ago - has surprised palaeontologists as most theories suggest that carnivorous dinosaurs got smaller as they got more bird-like.

Alien worlds, once hidden from knowledge, are now being discovered in droves, stunning astronomers with their unique features and sheer numbers. The discoveries are so common that more and more don't even get reported outside scientific circles.
A young star's strange elliptical ring of dust likely heralds the presence of an undiscovered Neptune-sized planet, says a University of Rochester astronomer in the latest Monthly Notices of the Royal Astronomical Society.
