Antibacterial Chemical disrupts hormone activities
December 10, 2007 05:13 PM - University of California, Davis, Newswire

Davis, California -  A new UC Davis study shows that a common antibacterial chemical added to bath soaps can alter hormonal activity in rats and in human cells in the laboratory -- and does so by a previously unreported mechanism.

The findings come as an increasing number of studies -- of both lab animals and humans -- are revealing that some synthetic chemicals in household products can cause health problems by interfering with normal hormone action. Called endocrine disruptors, or endocrine disrupting substances (EDS), such chemicals have been linked in animal studies to a variety of problems, including cancer, reproductive failure and developmental anomalies.

Scientists Discover How to Make Robots Bounce on Water
December 10, 2007 08:17 AM - , Environmental Graffiti

The way water striders walk on water was discovered years ago. The insect uses its long legs to help evenly distribute its tiny body weight. The weight is distributed over a large area so that the fragile skin formed by surface tension supports the bug on the water. However, the ability of water striders to jump onto water without sinking has baffled scientists, until now.

Grasscrete, the green alternative to standard concrete surfaces for parking lots, driveways, and access roads for vehicles or fire trucks. The benefit to Grasscrete for businesses and developers is that it drains at about the same rate as would an ordinary lawn in the same location. The presence of concrete has little effect on the drainage; the soil and the slope are the controlling factors which makes it beneficial for erosion control as well.
