Stanford researchers establish center for physics-based simulations of biological structures
... (Chris Zarins). Addressing these problems "makes sure we make contributions soon to the science," Altman said. "We have scientists in those domains who've signed up to be early users of our software and to give us feedback as to whether it's working or not working and what it needs to do." The center a...'Immediately open access' option for the leading journal Genome Research
... as our experience with this option grows, to make sure the journal's ability to contribute to the advance of science isn't undermined."

All we know for sure is that the number of older people with long-term care needs will increase with the growth of the older population over the next 30/40 years. We also know that most states are experiencing a great deal of fiscal pressure in their Medicaid programs. T...Study describes basic mechanism in cell growth control involving damaged DNA

"But after replication, CDT1 must be degraded to prevent re-replication before the cell finishes dividing. "And when DNA is damaged, the cell must find a way to very rapidly degrade CDT1 to prevent cont...UT Southwestern researchers uncover process for sugar-induced fat formation

In their experiments, the researchers examined the expression of nearly 8,000 genes simultaneously in a colon cancer cell line (called HCT116).

This process of internal house-cleaning in the cell is called autophagy literally self-eating and it is now considered the second form of programmed cell death (PCD).

They took a line of cancer cells that lack 5HT2AR and inserted the receptor gene. They found that these re-engineered cells were now susceptible to infec...Random gene activation helps ulcer bug escape immune system

Scientists aren't sure what, if anything, BabB sticks to, but they do know that its similarities to BabA include biochemical "hooks" at the beginning and end of the protein. These hooks anchor the proteins in the bacteria's cell wall. The BabA gene's middle section encodes...New bulls may revive the Texas state Bison Herd

So last year, Texas Parks and Wildlife representatives, along with Texas A&M researchers traveled to New Mexico and chose three 1-year-old bison bulls.

... visual patterns," Kramer said. "Sometimes I'm not sure where the science ends and the fantasy begins, but I think we can make it work." "With this technique, you also could confer light sensitivity on organisms that normally don't have vision, such as the nematode worm C. elegans," Trauner said.

... the team have not yet tried this. Bishop is not sure why rRNA breaks down more slowly, but he believes it may be because rRNA is protected by proteins that bind it into ribosomes- part of the cell's machinery for producing proteins.
