Radioactive battery from nuclear waste material

Personal Nuclear Power: New Battery Lasts 12 Years By Robert Roy Britt LiveScience Senior Writer posted: 13 May 2005 11:02 am ET

A new type of battery based on the radioactive decay of nuclear material is 10 times more powerful than similar prototypes and should last a decade or more without a charge, scientists announced this week. Read more...

Self Clonning Robot

BIRDS and bees do it - now machines can reproduce too. The first scalable robot to have built an exact copy of itself could herald a fundamental rethink of how robots may be used to explore other planets. Read more...

Bendable Concrete

A new type of fiber-reinforced bendable concrete will be used for the first time in Michigan this summer- and University of Michigan scientists hope that their new material will find widespread use across the country. The new concrete looks like regular concrete, but is 500 times more resistant to cracking and 40 percent lighter in weight. Tiny fibers that comprise about 2 percent of the mixture's volume partly account for its performance. Also, the materials in the concrete itself are designed for maximum flexibility. Because of its long life, the Engineered Cement Composites (ECC) are expected to cost less in the long run, as well. Read more...

Bike -- The New Design

INDIANAPOLIS - Who can forget the thrill — and terror — of that first solo bicycle ride: Mom or Dad letting go, the magic of two-wheeled freedom and, inevitably, toppling over in a knee-scraping crash? Read more...
