Urban pollution affects cardiac function: Initial results in the healthy rat
03/17/2010 - 19:00
In the healthy rat, prolonged exposure to carbon monoxide (CO) under conditions that mimic urban pollution leads to changes to cardiac morphology and function. Compensatory mechanisms develop in these animals to sustain normal cardiac activity, but they become more vulnerable to heart disease. The results provide cellular proof in the rat of a direct effect of urban pollution on cardiac function. Studies are ongoing to verify these findings in humans.

Frogs, foam and fuel: Solar energy converted to sugars
03/17/2010 - 10:00
In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant -- like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers are doing something about that.

In search of key blue ingredient in ancient Egyptian pottery
03/16/2010 - 23:00
As one of the "generic geologists" on a dig called the Dakhleh Oasis Project, associate professor Jennifer Smith was asked to sample the alum from ancient mines and to determine whether it could be the source of the blue in the "blue painted pottery" found at sites dating from the New Kingdom. It was a small question but an intriguing one.

Prior herbicide use -- not irrigation -- is critical to herbicide efficacy
03/16/2010 - 23:00
Crop and herbicide use history are more critical to herbicide efficacy and environmental safety than the timing and amount of irrigation water used, according to agricultural scientists.

An organic approach to pest control: releasing super-sexed (but sterile) male insects
03/16/2010 - 23:00
An improved method for sustainable pest control using "super-sexed" but sterile male insects to copulate with female ones is being developed by agricultural researchers in Israel. The scientists thus hope to offer yet another efficient and promising avenue for supplying produce to the market by eliminating pests without damage to the environment.
