Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...ctive experiments to modify the enzyme complex for improved efficiency." What the scientists found in their simulations ?a "virtual microscope" that let them zoom in on previously invisible details -- is that initially the binding part of the enzyme moves freely and randomly across the cellulose surface, ...

Multiple malaria infection inhibits spread of parasite

...before starting the research on immunity. With the improved test, the researchers studied how people not previously exposed to malaria become infected or immune. Migrants in the province of Papua in Indonesia, who had not previously been exposed to malaria were investigated for this purpose. Malaria is highly...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

Researchers open the way for improved study of hepatitis C virus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines. The related report by Lázaro et ...

Plastic that degrades in seawater could be boon for cruise industry and others

..., some drugs were able to delay delivery, but none improved the baby’s health outcome. This study is the first to show that the baby benefited from the therapy, especially those who are born very prematurely (at 24 to 28 weeks). Using a composite measure of the newborn’s health including perinatal death, mark...

Improving outcomes in premature births
