'Shaquille O'Neal' Of Bacteria Big Enough To See With Naked Eye
Cornell researchers are studying bacterium big enough to see -- the Shaquille O'Neal of bacteria. The secret to an unusual bacterium's massive size -- it's the size of a grain of salt, or a million times bigger than E. coli bacteria, and big enough to see with the naked eye -- may be found in its ability to copy its genome tens of thousands of times.

Women Who Breastfeed For More Than A Year Halve Their Risk Of Rheumatoid Arthritis
Women who breast feed for longer have a smaller chance of getting rheumatoid arthritis, suggests a new study. The study also found that taking oral contraceptives, which are suspected to protect against the disease because they contain hormones that are raised in pregnancy, did not have the same effect. Also, simply having children and not breast feeding also did not seem to be protective.

Treatment For Severe Blood Loss: Less Is More
Intravenous administration of isotonic fluids is the standard emergency treatment in the U.S. for patients with severe blood loss, but now bioengineering researchers have reported improved resuscitation with a radically different approach. Building on earlier studies in humans that have shown benefits of intravenous fluids that are eight times saltier than normal saline, the researchers combined hypertonic saline with viscosity enhancers that thicken blood.

The students are using the fruit to produce solar energy. Actually, they are using the dye from the fruit in a process to create solar cells.
