  where conditions are right, will there be life? LITU scientists have been leading innovators in suggesting new scenarios, which might have led to the origin of life on Earth and elsewhere. Did it happen in Darwin’s "warm little pond", or at the steaming undersea cauldrons of the ocean, spewing forth hot water, rich in suitable chemicals?
Image of bread Yeast intake linked to longevity  - BBC  Restricting the amount of yeast in the diet can increase life expectancy by 50%, research into fruit flies has shown. It is not yet clear whether the same might be true in humans. But the authors say their findings hint it might be what you eat rather than total calorie intake that influences longevity, contrary to current belief. "The dramatic impact of reducing yeast suggests that protein or fat plays a greater role in fly longevity than sugar." "Diet is an important issue we have largely ignored until recently." He stressed that too little food could also be harmful.  

Roomba vacuum inventor turns robots into reality - Seattle Times  Left:  Helen Greiner, chairman and co-founder of iRobot, stands beside its chief military robot, a track-wheeled rover called the PackBot that has disarmed roadside bombs in Iraq and Afghanistan.  Watching the original "Star Wars" movie as a mathematically inclined 11-year-old, Helen Greiner dreamed of someday creating a robot like the heroic R2-D2. After enduring plenty of lean years chasing that elusive vision as a co-founder of iRobot, Greiner can now boast a product that whirs and chirps much like the character she to this day calls her "personal hero."  Some 1.2 million of the disc-shaped, Roomba robotic housekeepers have been sold in 25 countries in the past 2 ˝ years. For the 37-year-old Greiner, the success of the Roomba and of iRobot's military machines validates the transformation of robots from the stuff of fantasy to practical tools. IRobot is now the world's largest firm solely devoted to robotics, with more than 200 employees.
