Couple of interesting news items:
====

First one is excerpted from 60 Second Science Podcast by Scientific
American:


"You've no doubt heard that grapefruit juice can greatly increase the
effects of some drugs. Even to a dangerous degree. Pharmacologist David
Bailey made that discovery almost 20 years ago. A substance in the juice
blocks an enzyme that breaks down the drugs. Now Bailey's back with a fresh
finding-grapefruit juice, orange juice, apple juice and other fruit juices
can also severely decrease the absorption of certain drugs. He announced
this discovery August 19th at the national meeting of the American Chemical
Society in Philadelphia."

various

disease<http://www.sciam.com/topic.cfm?id=heart-disease>,
> infection and even the rejection of transplants. Key ingredients in the
> juices appear to block a molecule that carries drugs from the small
> intestine into the bloodstream. So a lot of the medication gets flushed
out
> without ever reaching its target. Bailey says, "This is just the tip of
the

> go."

Also, a story appeared yesterday in my news browsing by one of the science
journals (I'll have to go look it up if anyone wants the name) but it
basically said they've found that the old practice of hyping up young horses
on oats, barley, molasses, and other grains is counterproductive.   They
used to think it gave the horses extra energy for the training, and it gave
them that glossy coat and bright eyes that people liked to see.  But a
careful study recently revealed that hmmmm....it seemed that the horses who
had all the grains/sugar were anxious and restive, were more unstable
mounts, and were less responsive to the critical first stages of training
than the more 'placid' horses who only had grass and hay.  The latter
responded better to training and made calmer mounts.

Go figure.
