Herpes virus hijacks DNA repair process
...is inappropriate activation, orf36, is a kinase, a type
of protein that chemically modifies other molecules to activate different processes or transmit signals. Genetic comparisons with several human herpes viruses revealed kinases similar to orf36 in the human viruses. Scientists then took a similar kina...

...blastoma multiforme, the most aggressive form of a type
of brain tumor called glioma. The median survival for patients with glioblastoma multiforme is 12 to 15 months. Researchers hope that identifying the genes that control the progression of the disease will help them develop new therapies. Samuel...
UCR biologists unravel the genetic secrets of black widow spider silk
...tures and specialty ropes. Dragline silk just one type
of the seven different silks that an individual spider produces are used by spiders as the structural foundation of their webs and to support their body weight as they move about. The dragline silk of black widows is one of the strongest and toughes...
A fly lamin gene is both like and unlike human genes
...n adults walk poorly and can't fly like aged wild type
flies. This suggests that lamin mutations might cause neuromuscular defects, premature aging, or both. The resemblance of Drosophila lamin phenotypes to human laminopathies provides an interesting case of gene expression and function diverging throug...
Identification of genetic risk factor for coeliac disease promises improved treatment
...new that coeliac individuals had a specific tissue type
which recognised wheat proteins. We did not know why healthy individuals who had the same tissue type
did not develop symptoms or disease. The first findings from our study suggest that interleukin gene...
Scientists propose the kind of chemistry that led to life

New study finds genetically engineered crops could play a role in sustainable agriculture
...swer is that it depends to a large degree upon the type
of comparison one makes. When Bt crops are compared to crops sprayed with insecticides, the Bt crops come out looking quite good. But when Bt crops are compared to crops without insecticides, there are reductions of certain animal groups that warran...
Turning the tables in chemistry
...kles swimming in metal ions are one example of the type
of undergraduate chemistry class demonstration that helps make a future in science a bright possibility, rather than a total turn-off, for many students. In a commentary in this months Nature Chemical Biology, Brandeis University and Howard Hughes ...
QUT microgravity tower attracts global scientific community
...sual methods of zero-gravity testing. To do this type
of research without a microgravity tower is often extremely expensive and time-consuming because researchers have to send their experiment into space on a space shuttle or use a vomit comet, a NASA jet that changes altitude rapidly, to negate gravity...
New bacterium discovered -- related to cause of trench fever
...mised patients. But when I saw this patient, this type
of infection had never been seen at UCSF, and the bacterium causing the infection was unknown. Koehlers group went on to discover that two different Bartonella species can cause these disfiguring and potentially fatal infections in AIDS patients. ...
Largest ever study of genetics of common diseases published today

1 diabetes and three new genes for Crohn's disease (a type
of inflammatory bowel disease). For the first time, the researchers have found a gene linking these ...
