Internet viruses help ecologists control invasive species

Studying how computer viruses spread through the internet is helping ecologists to prevent invasions of non-native species. New research published today in the British Ecological Society's Journal of Applied Ecology, describes the use of network theory to predict how the spiny wa...

Virologists make major step towards understanding the process of HIV infection

...IV structure protein by about one half, infectious viruses continue to be generated. Using electron microscopy, Zentgraf’s team was able to show that appearance and shape of the virus particles thus created cannot be distinguished from normal HIV.

Gene silencing technique offers new strategy for treating, curing disease

...r research, to determine whether the human body or viruses and bacteria make RNA sequences like this to control gene expression," Dr. Corey said. So far, the researchers have inhibited the expression of nine different genes in cancer cell cultures. Dr. Corey said it's not clear whether the RNA is actually b...

Where Bacteria Get Their Genes

...commonly, genes are transmitted by bacteriophages, viruses that specifically hijack bacteria cells. Like tiny syringes, phages inject their own genetic material into the host cell, forcing it to produce new phages. During such an event, genes from the bacterial genome can be incorporated into the newly made ...
