Politics of Water: Ancient Sea on Mars Begs Human Exploration - Space.com  Space agency officials said the briney find by the Opportunity rover has singled out its Meridiani Planum landing site for future robotic exploration and given a timely boost to President George W. Bush's recently stated vision of eventually sending humans to take a more personal look around. "And it's in due course that human explorers will follow," O'Keefe said. 
A 'One-Step' Method To Make Polymer Nanowires - SpaceDaily  A powerful one-step, "chain growth" method should make it easier to design and synthesize a variety of highly conductive polymers for different research and commercial applications, according to a presentation by the method's developer, Carnegie Mellon University chemist Richard McCullough. With this research, funded by the National Science Foundation, researchers can form highly conductive nanowire sheets within polymer blocks or create a plethora of new conducting polymers. "The chain-growth method eliminates six production steps to create block co-polymer nanowires that conduct electricity a million times better than other conducting copolymers."said McCullough. Regioregular polythiophenes have a wide range of potential applications, such as dissipating static electrical charges that build up on coated floors or use in disposable devices called radio frequency identification tags.


Heart death 'may be eradicated'   - BBC  Premature death from heart disease in England could be almost unheard of within a decade, the government's heart tsar has predicted. Figures show that in 1990 more than 90 men under 65 per 100,000 died of heart disease. By 2000 the figure was 50. If the trend continues it could reach almost zero by 2013. Deaths among women under 65 have also shown a steady decline, from around 25 per 100,000 in 1990 to around 10 in 2000. Dr. Boyle warned that factors such as increasing rates of obesity and diabetes may stall progress.
