Introducing NUGGET: NASA's New 'Tricorder' - Space.com  NUGGET (Neutron/Gamma Ray Geologic Tomography), an instrument containing a neutron generator, a neutron lens and a gamma-ray detector, could be used to investigate important biological indicators of life on distant worlds - just like Star Trek's tricorder. The sy stem provides a three-dimensional scanning instrument that focuses a beam of neutrons into an object. When the nucleus of an atom inside the rock captures the neutrons, it produces a gamma -ray signal      
Experts home in on cancer genes  - BBC  Scientists are closing in on more genes linked to the development and progression of breast cancer. Scientists have now pinpointed another fault which can develop - and have identified four genes which could be the culprit. Professor Carlos Caldas at the University of Cambridge told the BBC News website, "We don't know which of the four genes is the culprit yet. "But we know that women who have increased copies of this fragment of chromosome eight have a poor prognosis. We could use this to identify tumours that are more aggressive and target them with more aggressive treatment."  

Koreans produce world’s first cloned dog - MSNBC  Left: At 2 months of age, Snuppy, the first cloned dog, appears at right with the 3-year old male Afghan hound whose skin cells were used to clone him.  South Korea’s pioneering stem cell scientist has cloned a dog, smashing another biological barrier and reigniting a fierce ethical debate — while producing a perky, lovable puppy. The researchers, led by Woo-Suk Hwang, insist they cloned an Afghan hound, a resplendent supermodel in a world of mutts, only to help investigate human disease, including the possibility of producing stem cells for treatment purposes. But others immediately renewed calls for a global ban on human reproductive cloning before the technology moves any farther. Uncertainties about the health and life span of cloned animals persist; Dolly died prematurely in 2003 after developing cancer and arthritis. Wilmut and others complimented Hwang’s achievement. But they said politicians and scientists must face the larger and more delicate issue — how to extend research without crossing the moral boundary of duplicating human life in the lab.
