Computers to be used to find blueprint for new influenza drug

...ug would be chemically similar to the sialic acid, but would act to inhibit the sialidase. This would hinder the virus from entering the cells, and from leaving them should they gain entry, thereby controlling the spread of the infection. Because of similarities between the enzymes used by different vir...

...p," he says. "It's very time consuming to do that, but without that information we don't know how these parasites are transmitted." And without basic systematics and taxonomic information about parasites, Dr. Brooks points out that we lack the ability to predict and thus prevent emerging parasitic disea...

The statistically strong association with Kawasaki disease,however, was "quite surprising." Noting that previous attempts to linkKawasaki disease to bac...

Ancient olfaction protein is shared by many bugs, offering new pest control target

Future designs of pesticides and disease-controlling insect repellents may be able to utilize this commonality to "blind" the insects to the smell of their prey. Walton D. Jones, Thuy-Ai...
