...course, the more basic question is, How much do masks really help to stem the spread of disease? It's unclear, according to the CDC, which isn't recommending that people wear masks amid the current H1N1 outbreak. The CDC website says that "very little is known about the benefits" of wearing masks during a pandemic, and that the best preventive steps are frequent hand-washing and covering one's mouth when coughing or sneezing. Along with these strategies, the most effective techniques for preventing contagion are so-called social-distancing measures, such as closing schools, churches, theaters and other...
...certainly a daunting challenge to begin teasing out the individual genes that may contribute to autism, as the UCLA team has with CACNA1G, but databases like AGRE make the job slightly easier. The next step will be to try to use known autism genes to help develop screening tools or early interventions. "We are going to have a much better understanding of the causes of autism over the next five to 10 years," says Dawson. "We're in a period of great discovery...
When hundreds of bodies suddenly began turning up in São Paulo in May 2006, many people suspected a secret war had taken place.

For her part, the Queen, who has long championed animal rights and is herself a vegetarian, forwarded the organizations' letter to the city government, urging them to consider...
...Swine flu's known symptoms vary little from those of winter flu, which is one of the main reasons it is difficult to track. Those with underlying health problems, such as diabetes or heart disease, seem especially vulnerable -a particular concern for a nation like Japan with a high elderly population. None of the infected are in critical condition, but, as deadly influenza pandemics have proved in the past, the current strain of H1N1 may mutate and become far more virulent - and lethal - by the next flu season.
