Venter Institute Claims Patent on Synthetic Life
jimsnail writes "J. Craig Venter and the Institute that bears his name are again moving into new territory in the field of genetics. Genetic patents, that is. They are seeking a broad patent that would give them ownership of a 'free living organism that can grow and replicate' constructed entirely from synthetic DNA. The ETC Group is challenging the claim. 'Scientists at the institute designed the bacterium to have a "minimal genome"--the smallest set of genes any organism can live on. The project, which began in the early 2000s, was partly a philosophical exercise: to help define life itself better by identifying its bare-bones requirements. But it was also fraught with commercial possibilities: if one could reliably recreate a standardized, minimal life form, other useful genes could be added in as needed for various purposes.'" -
Raining Extraterrestrial Microbes in Kerala?
jdfox writes "World Science is reporting on a controversial paper to be published shortly in the peer-reviewed research journal Astrophysics and Space Science, describing a strange red rain that fell in India in 2001, shortly after a meteor airburst event in the area. The authors posit that the red particles found in the raindrops may be extraterrestrial microbes. The authors' last two papers on the subject were unpublished: this published paper is more cautious. The paper can be viewed online, and should obviously be considered in context. More info on the 'panspermia' hypothesis can be found at Wikipedia." -
Alex, The Brainy Parrot Who Knows About Zero
Roland Piquepaille writes "Alex is a 28-year-old grey parrot who lives in a lab at Brandeis University in Waltham, Mass., and can count, identify objects, shapes, colors and materials. And now, Alex has grasped the concept of zero, according to World Science. In fact, Alex can describe the absence of a numerical quantity on a tray containing colored cubes. When a color is missing, Alex consistently identified this 'zero quantity' by saying the label 'none.' You might think that this is just a parrot trick, but this research about 'bird intelligence' might also help autistic and other learning-disabled children 'who have trouble learning language and counting skills.' This overview contains other details, references and a picture of Alex counting his colored cubes." -
Sunlight in a Tube
Elitist_Phoenix writes "Scientists are developing a technology to save energy by transmitting sunlight into buildings through tubes. Indoor electric lighting is the largest consumer of electricity in commercial buildings. Their new system. called hybrid solar lighting, would reduce this energy usage with fixtures that supplement or completely replace electric light with sunlight, at times when its available. The system is called hybrid solar lighting (Google)." -
Model Of Mummy's Head Made Without Unwrapping
jekluk writes "This story in World Science has a cool picture. Basically they used CT scanning to create a 3D model of a mummy's head without unwrapping a stitch of the mummy. Looks very lifelike, just as if the guy is asleep. The details are shown down to the mole on his forehead."
