Mineral Gas Pump Has No Moving Parts

November 30, 2008 – 12:06 am

Scientists have discovered that a type of hard mineral called zeolite can provide a high rate of gas flow in a micro-scale gas pump. Because the pump is based simply on temperature differences and has no moving parts, it could provide reliable and precise control of gas flow for a variety of applications, such as gas-sensing breath analyzers and warfare agent detectors. Mechanical engineers Naveen Gupta and Yogesh Gianchandani from the University of Michigan have published their study.

Can Grapes Fight High Blood Pressure?

October 31, 2008 – 11:18 pm

Could eating grapes help fight high blood pressure related to a salty diet? And could grapes calm other factors that are also related to heart diseases such as heart failure? A new University of Michigan Cardiovascular Center study suggests so. The new study, published in the October issue of the Journal of Gerontology: Biological Sciences, gives tantalizing clues to the potential of grapes in reducing cardiovascular risk. The effect is thought to be due to the high level of phytochemicals.

New Bluetooth System Able to Guide the Blind

September 20, 2008 – 11:11 pm

A new Bluetooth system designed primarily for blind people places a layer of information technology over the real world to tell pedestrians about points of interest along their path as they pass them. The Talking Points urban orientation system was developed at the University of Michigan. Researchers will present their work at two conferences on Sept. 24. “Blind people can get from point A to point B. They learn to count steps if they have to, but they also miss the journey.”
