November 9, 2009 -- Tooth enamel is hardest material in the human body because it's made almost entirely of minerals. As tough as it may be, however, enamel can be broken down by bacteria, forming cavities and eventually destroying the tooth. That's why dentists repair cavities by filling them with a material to replace the lost enamel. The most common such restorative is a material invented in the 19th-century known as amalgam -- the classic silver-black fillings many people have.

SANTA CRUZ, CA--Studies conducted in California and elsewhere provide support for the use of marine reserves as a tool for managing fisheries and protecting marine habitats, according to biologists at the University of California, Santa Cruz.
A recent study in the Gulf of California, for example, confirmed the validity of a key concept behind marine reserves--the idea that offspring produced in a protected area can replenish the stocks of harvested species outside the reserve.

The remains of a Minoan-style wall painting, recognizable by a blue background, the first of its kind to be found in Israel, was discovered in the course of the recent excavation season at Tel Kabri. This fresco joins others of Aegean style that have been uncovered during earlier seasons at the Canaanite palace in Kabri.

Simple computerized alerts can help curb the impulse to prescribe unnecessarily expensive, heavily marketed drugs.

Companies that commit fraud can find innovative ways to fudge the numbers, making it hard to tell something is wrong by just looking at their financial statements. But research from North Carolina State University unveils a new warning system that sees through accounting tricks by evaluating things that are easily verifiable, such as the number of employees or the square footage that a company owns. If a company says that its profits are up, but these nonfinancial measures (NFMs) are down, that's a sign something is probably wrong.
People would be willing to pay more for products that carry detailed nutritional information than for the so-called light items.

Antibiotic over-prescription is promoted by pediatricians' perception of parents' expectations.

Researchers reporting in BioMed Central's open access journal Conflict and Health found that the discrepancy in media reporting of casualty numbers in the Iraq conflict can potentially misinform the public and contribute to distorted perceptions and gross underestimates of the number of civilians killed in the armed conflict.
Racial discrimination is a major threat to African American women's mental health. It undermines their view of themselves as masters of their own life circumstances and makes them less psychologically resilient and more prone to depression. These findings (1) by Dr. Verna Keith, from Florida State University in the US and her colleagues, are published online in Springer's journal Sex Roles.
