Fully differentiated mouse cells, such as mature B cells, can be reprogrammed to embryonic-stem-cell-like induced pluripotent stem cells, without the use of an egg. Using reprogrammed mature B cells, researchers may be able to create mouse models that will aid in understanding autoimmune diseases such as multiple sclerosis and type 1 diabetes.
Mercury In River Moves Into Terrestrial Food Chain Through Spiders Fed To Baby Birds

Songbirds feeding near the contaminated South River are showing high levels of mercury, even though they aren't eating food from the river itself, according to a new article in Science. Mercury is one of the world's most troublesome pollutants, especially in water. "The birds eat a lot of spiders... The spiders have a lot of mercury in them and are delivering the mercury to these songbirds," one of the researchers said.
Hepatitis C: Identification Of A Protein That Inhibits The Virus

Scientists have provided evidence of a protein that inhibits the hepatitis C virus at an early stage of its infective cycle. This research suggests possible new perspectives for the development of therapies to block the virus before it enters a cell. Hepatitis C is a major public health problem that affects some 130 million people throughout the world.
First Successful Libraries Of Avian Flu Virus Antibodies Created

Scientists have created the first comprehensive monoclonal antibody libraries against avian influenza using samples from survivors of the 2005/2006 "bird flu" outbreak in Turkey. These antibody libraries hold the promise for developing a therapy that could stop a pandemic in its tracks and provide treatment to those infected, as well as potentially pointing the way towards the development of a universal flu vaccine.
Molecular Movies Allow Scientists To See Molecular Movements Firsthand

They may never win an Oscar, but scientists have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now. Biological and organic molecules in solution are far more complex than the standard crystalline structures of salt or metals since they are constantly moving and changing over time. These motions have not yet been seen directly, but scientists using the high intensity x-rays at the Advanced Photon Source have measured images that are "blurred" by these motions and have used them to create more accurate movies of molecular motions.
Flu Viruses Take One-way Ticket Out Of Asia, Then Travel The World

Seasonal influenza strains constantly evolve in overlapping epidemics in Asia and sweep the rest of the world each year, an international research team has found. These findings suggest that by focusing surveillance efforts on East and Southeast Asia, researchers may be able to extend their forecast of the flu strains most likely to cause epidemics, which may in turn help experts decide which strains should go in the flu vaccine each year.

In a few minutes a computer can make a mistake so great that it would have taken many men many months to equal it.
The victory of success is half won when one gains the habit of setting goals and achieving them. Even the most tedious chore will become endurable as you parade through each day convinced that every task, no matter how menial or boring, brings you closer
