Herpes virus hijacks DNA repair process

June 13, 2007 -- Scientists probing the details of viral infection have discovered an intriguing surprise: in mice, herpes viruses hijack their host cells' tools for fixing DNA damage and use those tools to enhance their own reproduction. The DNA damage response normally fixes DNA err...

New study sheds light on 'dark states' in DNA

...matter in the universe ?there was no direct way of probing it. The Ohio State chemists used a technique called transient absorption, which is based on the idea that molecules absorb light at specific wavelengths, and allows them to study events happening in less than a picosecond. They found that DNA dissi...

Primitive yeast yields secrets of human cholesterol and drug metabolism

By first probing the way primitive yeast make cholesterol, a team of scientists has discovered a long-sought protein whose human counterpart controls cholesterol production and potentially drug metabolism. The collaborative study by investigators at Johns Hopkins Un...

T-ray breakthrough could make detecting disease far easier

...ch could be useful in applications like endoscopic probing for cancerous cells or explosive detection. "This is a significant development that would allow unprecedented accuracy in studying tiny objects and sensing chemicals using T-rays" said Dr Stefan Maier, of the University of Bath's Department of P...

Gene-bender proteins may sway to DNA

... sub-microseconds. It gave us a new time window on probing protein-DNA interactions," Ansari said. That broader time window, obtained in combination with the stopped-flow measurements, provided the first direct observation of DNA bending when bound to a DNA-bending protein. "We found that the time-scale...

Researchers show how brain decodes complex smells

...nput is smell, sight or sound. Shea suggested that probing the olfactory system could help scientists better understand, for example, how the various biological and neurological components underlying perception formed and evolved. ...

Long-term changes in experience cause neurons to sprout new long-lasting connections

... "What we think they are doing is reaching out and probing for potential neuronal partners. And while most of them retract, with novel sensory experience some populations of these new spines make connections that constitute beneficial new wiring. So those spines gain bulk and are stabilized as persistent spi...

Molecule by molecule, new assay shows real-time gene activity

...side -- greatly increases scientists' precision in probing genetic activity. Using the new assay, described this week in the journal Science, researchers led by Harvard's X. Sunney Xie counted, one by one, protein molecules generated in small bursts within cells as multiple ribosomes bound to single copies ...

Mouse genome much more complex than expected

... from Australia, Asia, Europe and the US have been probing the genome of the mouse in a joint study lasting several years. Their results in some aspects have completely overturned geneticists' traditional assumptions. The findings are available in the prestigious journal Science on 2nd September. The general...

Embryonic stem cells accrue genetic changes

... or no measurable effect at all. In addition to probing changes in the nuclear and mitochondrial DNA sequences and copy numbers, the researchers examined whether the cells' genetic material had shifts in marks that sit on genes and are passed from cell to cell during cell division. These so-called epigene...
