This is SCIENCE FRIDAY. I'm Ira Flatow. White blood cells are part of our body's defense system. Their job is to attack invaders, and one of the first white blood cells sent out is the neutrophil. These neutrophils put out a trap to capture and destroy the invaders.

It's the exact opposite of what you want. But there may be a way to counteract this problem.
Archaeologists digging in the foothills of Iran's Zagros Mountains have discovered the remains of a Stone Age farming community. It turns out that people living there were growing plants like barley, peas and lentils as early as 12,000 years ago.

NPR's Wendy Kaufman reports.
And a remembrance, now. The, a computer visionary best known for inventing the mouse has died. As NPR's Laura Sydell reports, the mouse was just one small piece of what Douglas Engelbart contributed to the development of personal computers.
All 16 of the Flying Saucer pubs across the country, including San Antonio, have begun a month-long fundraising for prostate cancer awareness and early detection. The money raised will go to Pints for Prostates, a nonprofit that began in 2008 by a prostate cancer survivor.
"Anytime you're dealing with something cancer-oriented, awareness and early detection is very key," said Sam Wynne, Flying Saucer’s beer director and certified cicerone -- a beer and food pairing expert.
