Avid Radiopharmaceuticals announced that the U.S. Food and Drug Administration (FDA) Peripheral and CNS Advisory Committee provided strong support for development of amyloid imaging agents to test for the presence or absence of Alzheimer's disease pathology in people with symptoms of cognitive impairment. Avid's Phase II amyloid imaging compound, 18F-AV-45 (AV-45) is well positioned to rapidly enter late stage development based on the FDA Advisory Committee recommendations.

Spinner dolphins have long been known for their teamwork in capturing prey, but a new study using high-tech acoustics has found that their synchronization is even more complex than scientists realized and likely evolved as a strategy to maximize their energy intake.

After more than 20 years of research in the northern hardwood forests of Michigan, scientists have reached a surprising conclusion: Moderate increases in temperature and nitrogen from atmospheric pollution actually improve forest productivity.

A powerful antioxidant in green tea may prevent or delay the onset of type 1 diabetes, Medical College of Georgia researchers say. Researchers were testing EGCG, green tea's predominant antioxidant, in a laboratory mouse with type 1 diabetes and primary Sjogren's syndrome, which damages moisture-producing glands, causing dry mouth and eyes.

A historian has uncovered extensive archive material detailing the activities of the 'scuttlers' - one of Britain's earliest youth cults.

The researchers who first isolated cancer stem cells in adult brain tumors in 2004 have now identified a molecular mechanism that is involved in the development of these cells from which malignant brain tumors may originate. This could offer a target for scientists seeking treatments that would kill malignant brain tumors at their source and prevent them from recurring.

Alu retrotransposons are gradually changing human DNA by making copies of themselves and "jumping" to new locations. Their activity appears to depend on being able to mimic parts of the cell's internal machinery. To identify the Alu retrotransposons that are still capable of moving around, researchers divided them into families and tested a representative of each family in the laboratory.

The "name-letter effect," is a phenomenon which shows that we have a preference for things that begin with the same letter as our first name. Belgian psychologists wanted to know if this effect is strong enough to affect where we work. the researchers found 12 percent more matches between employee initials and their company's name than was expected based on a probability estimate, indicating "name-letter effect" occurs between employee names and the company they work for.
