WEST LAFAYETTE, Ind. - A group of Purdue University researchers has captured a key step in the metabolic process that allows materials, such as nutrients and drug treatments, to move in and out of cells.

A research team led by Jue Chen, an associate professor of biological sciences, obtained a snapshot of the tiny protein gate complex that opens and closes pathways through the protective cellular membrane. The gates, operated by small protein machines that push them open and closed, bring nutrients into the cell and flush out waste.

WEST LAFAYETTE, Ind. - To get more out of your next cup of tea, just add juice. A new Purdue University study found that citrus juices enable more of green tea's unique antioxidants to remain after simulated digestion, making the pairing even healthier than previously thought.

The study compared the effect of various beverage additives on catechins, naturally occurring antioxidants found in tea. Results suggest that complementing green tea with either citrus juices or vitamin C likely increases the amount of catechins available for the body to absorb.

December 1, 2007 02:13 PM -

Chicago - The Metropolitan Water Reclamation District of Greater Chicago, one of the nation’s largest water authorities, today announced that it has purchased 30 all-electric, low-speed MILES ZX40 cars as part of its strategy to slash fleet emissions and costs. The acquisition represents the largest purchase of MILES electric vehicles by a government agency. It is estimated that the vehicles will eliminate hundreds of thousands of pounds of greenhouse gas emissions each year in operation.

 

 

The ZX40 hatchbacks will be officially delivered to Water Authority Commissioners on Tuesday, November 27th at 12:00 p.m. during a ceremonial "plug-in," reflecting the fact that MILES cars and trucks are powered by industry-leading batteries that can be charged at any standard household or business outlet.
