Researchers finger the cause of 'gravity fingers'
Denise Brehm, Civil and Environmental Engineering
MIT researchers have found an elegant solution to a sticky scientific problem in basic fluid mechanics: Why water doesn't soak into soil at an even rate, but instead forms what looks like fingers of fluid flowing downward.

Saturation maps from a numerical simulation of the proposed model
show that the flow dynamics and the distinctive saturation overshoot
at the tip of the fingers agree with experimental observations.

Results Could Lead to New Treatments for Conditions From Inflammation to Cancer
LA JOLLA, CA, October 12, 2008—Excess nitric oxide production by one enzyme has been tied to human illnesses ranging from inflammation to cancer, but adequate treatments for the problem have been elusive. Now, work led by scientists at The Scripps Research Institute has revealed a new method for chemically targeting this single enzyme to block troubling nitric oxide production, without limiting its beneficial production by other closely related enzymes. This technique provides a general solution that should enable development of new drugs to treat medical problems tied to nitric oxide overproduction, such as arthritis, and may also aid the discovery of treatments for other conditions such as HIV/AIDS.

A family of biodegradable polymers called polyketals and their derivatives may improve treatment for such inflammatory illnesses as acute lung injury, acute liver failure and inflammatory bowel disease by delivering drugs, proteins and snips of ribonucleic acid to disease locations in the body.

Weizmann Institute Scientists discover: The pleasantness of an odor can be predicted from its molecular structure
What makes one smell pleasant and another odious? Is there something in the chemistry of a substance that can serve to predict how we will perceive its smell? Scientists at the Weizmann Institute of Science and the University of California at Berkeley have now discovered that there is, indeed, such a link, and knowing the molecular structure of a substance can help predict whether we will find its smell heavenly or malodorous.
