Going Private: The Promise and Danger of Space Travel - Space.com  Commercial zero-gravity jaunts became available for the first time this month. A successful manned space flight took place yesterday. And earlier this week, entrepreneurs announced a $50 million prize for the first private orbiting vessel, as well as public flights into space as early as 2007. "It's going to transform everything," George Whitesides, executive director of the National Space Society, said of private space tourism efforts. 
Captive Carry Rehearsal Flight Successful; Mach 10 Free Flight Next - SpaceDaily  NASA aeronautics researchers are looking forward to flying the X-43A research aircraft at speeds up to 10 times the speed of sound later this fall, following a successful "captive carry" dress rehearsal flight from NASA's Dryden Flight Research Center Sept. 27. The X-43A is powered by a revolutionary air-breathing supersonic-combustion ramjet - or "scramjet" - engine. If successful, the Mach 10 flight will break all speed records for an aircraft powered by an air-breathing engine. Project engineers are expected to set a tentative date for the final X-43A flight for early November. 


'Tomato treatment' slows cancer  - BBC  In their mice research, the Dutch scientists found a low dose of the synthetic lycopene slowed the growth of human prostate tumours implanted in the mice by over 50% by day 42 of the study, compared to mice who had not had the treatment. And when the lycopene was combined with vitamin E, it reduced the growth of tumours by up to 73%. The researchers found that levels of PSA (prostate specific antigen) matched the growth of the tumour, meaning that can be used to monitor the treatment's effects in men. "What was particularly marked was that it was the low dose of both lycopene and vitamin E that was the most effective."
