Preparing for flu pandemic: Pall breathing filters can help protect patients, healthcare workers
...ng hydrophobic (ability to repel liquids) and also demonstrating high levels of viral retention, would be effective. These criteria are even more critical with influenza, due to its likely modes of transmission -- through droplets in the air and contaminated fluids, such as saliva and bronchial secretions.

...t. This study adds to a growing body of literature demonstrating the potentially adverse consequences of genistein on the reproductive system. "Although we are not entirely certain about how these animal studies on genistein translate to the human population, there is some reason to be cautious," said Dr. David A....New cellular flaw found in some virulent breast cancers
... highly resistant to ErbB-2-caused breast cancers, demonstrating that blocking CDK4 was not harmful to the mice. That research was carried out by scientists at Tufts-New England Medical Center, Harvard Medical School, and Massachusetts Eye and Ear Infirmary, together with Sicinski. The identification of the cyc...How taste response is hard-wired into the brain
... the January 19, 2006, issue of Neuron experiments demonstrating just such a hard-wired circuitry. Their findings, they said, favor a model for taste encoding in the brain that holds that specific cells are dedicated to detecting specific tastes. Competing models hold that multiple neurons combine information to e...New Zealand tops environmental scorecard at World Economic Forum in Davos
