Mouse With Human Liver: New Model for Treatment of Liver Disease

How do you study-and try to cure in the laboratory-an infection that only humans can get? A team led by Salk Institute researchers does it by generating a mouse with an almost completely human liver. This "humanized" mouse is susceptible to human liver infections and responds to human drug treat... Read More

Budding versus Binary Fission

Elio Schaechter of Small Things Considered asks if there is an evolutionary advantage for budding, where cell division is asymmetrical (yeast is an example), over binary fission, asexual reproduction by cell division?

Snippet:

"Binary fission is a most impressive invention. In one fell swo... Read More

Swine flu wanes, but experts say pandemic strain could reemerge

Even as officials from the Centers for Disease Control and Prevention are announcing that the epidemic of the H1N1 flu is no longer widespread in any state, no disease expert is willing to say there isn't a third -- or fourth -- wave of swine flu in the country's future.

Influenza transmissio... Read More

Gallstones play key role in perpetuating typhoid

A new research suggests that typhoid fever bacteria collect on gallstones to perpetuate the disease.

People who harbour these bacteria in their gallbladders, even without symptoms, can infect others with active typhoid fever, especially in developing areas of the world where sanitation is poo... Read More

Your old sofa - and much more - could be composted, say scientists

Polyurethane plastics used to make a host of products from furniture fillings to shoe soles, cable insulation and paints – and which can be difficult to recycle – could soon be degraded in compost heaps, thanks to a study at the University of Manchester.

Architecture of a bullet-shaped virus

Since electron micrographs first revealed the bullet-shaped morphology of vesicular stomatitis virus (a virus related to rabies virus), understanding the architecture has been elusive. It was known that the RNA genome is wrapped in a helical structure by the viral nucleocapsid (N) protein, but h... Read More

Virus may incubate in icy lakes: researchers; Norwalk affects millions annually
