Transplant cures man of diabetes  - BBC  A 61-year-old man has become the first person in the UK to be cured of type 1 diabetes. After receiving insulin-making cells from the pancreases of dead donors, Richard Lane of Bromley, Kent, no longer needs insulin injections. But the technique is not perfect. Many patients still require top-up insulin. He now has to take drugs to stop his body rejecting the transplanted cells. Two other UK patients who have been treated with the procedure still need small doses of insulin. Scientists have also been looking at ways to make more of the cells required using stem cells.
Researcher Describes New Type Of Strong, Lightweight Metallic Material - SpaceDaily  Left:  The laminate performed spectacularly in depth-of-penetration ballistics tests, but its greatest potential may derive from its ability to be tailored to meet specific engineering requirements.  "The new material we developed is environmentally safe, and while its stiffness equals that of steel, it's only half as dense," said Kenneth S. Vecchio, author of the paper and a professor of mechanical and aerospace engineering in UCSD's Jacobs School of Engineering. The new material is made primarily of two lightweight metals. Vecchio alternated layers of aluminum and titanium alloy foils, and compressed and heated them

Hunt for Mars life will go deep ... - MSNBC  Left:  An artist's conception shows a drilling operation designed to probe Mars' deep subsurface. Astrobiologists say microbes could find a suitable environment in caves or even rock fractures, protected from ultraviolet radiation.  The hunt for some form of life elsewhere in our universe may spur a veritable fleet of robot orbiters, landers and rovers to study the surface of Mars in the coming years. But they might look in the wrong place. Instead of probing for signs of alien life on Marsí harsh surface, some researchers have suggested looking inside the planet, where there is mounting evidence of water ice near the equator and the potential for underground aquifers that could support basic, microbial organisms. Spirit and Opportunity, the two robots currently exploring the Red Planet under NASAís Mars Exploration Rover mission, have proved that water shaped the development of rocks on the planetís surface. Meanwhile, Europeís Mars Express spacecraft, now orbiting the planet, is preparing to unfurl a radar instrument that researchers say might find pockets of liquid water in subsurface caves or voids. Recent reports by U.S. and European researchers have hinted at connections between the presence of methane and other gases in Marsí atmosphere and the possibility of water-harboring subsurface caves capable of sustaining life. The theory is similar to actual conditions found in deep caverns on Earth.
