Researchers discover new mechanism of drug that alters genetic makeup of viruses
... biochemistry and molecular biology at Penn State, reveals that ribavirin, a synthetic compound that inhibits RNA viruses by working at the cellular level, also possesses an ability to alter the structure of the viruses at the genetic level. Researchers used poliovirus as the experimental model for their wo...Researchers reveal insidious role of a 'serpin' in Alzheimer's Disease
...t study, conducted in genetically engineered mice, reveals that increased production of ACT in the brain strongly increases the build-up of amyloid proteins, which is associated with damage to brain cells within and around the plaques. "We speculate that reducing or inhibiting the plaque-enhancing activity ...Study reveals structure of DNA packaging motor in virus
...ow some viruses package their genetic material and reveals a new type of biological motor system. Scientists at Purdue University and the University of Minnesota have solved the three-dimensional structure of the central component of a biological "motor" that powers the DNA packaging system in a virus, pr...First-ever complete plant genome sequence is announced
International team reveals DNA secrets of Arabidopsis thaliana Genetics reached a major milestone today as an international research team announced it has completed the first plant genome sequence.

...logists at UCLA and three Swedish universities now reveals some of this history. The biologists, writing in the Jan. 19 issue of the journal Science, show that today's domestic horse resulted from the interbreeding of many lines of wild horses in multiple locations. The taming of wild horses was extensive an...Friendly microbes control intestinal genes, study finds
... and the microbes that live in our body. The study reveals that microorganisms in the gut influence the expression of a number of genes that are important to intestinal development and function. "We live in a world predominated by microbes," explains Jeffrey I. Gordon, M.D. "These organisms have co-evolved ...More help for infertile women with polycystic ovary syndrome
