Researchers identify molecular anchor that allows bacterial invasion of central nervous system

...t allows bacteria to invade the nervous system may hold the key to treating many types of bacterial meningitis, a University of California, San Diego (UCSD) School of Medicine study has found. By blocking the molecule's anchoring ability, researchers may be able to find a way to stave off the most commo...

Normal chromosome ends elicit a limited DNA damage response

...e misguided repair attempts the cap is supposed to hold at bay, reports the Salk team, led by Jan Karlseder, in the current issue of Molecular Cell. Scientists had long surmised that the protective telomere-protein complex had to unravel when enzymes need to gain access in order to copy the chromosome's...

The earliest animals had human-like genes

...n the current issue of the journal Science. Genes hold the recipes for proteins. The genes of animals usually contain extra bits of DNA sequence, called introns ?information which has to be removed as cells create new molecules. The number of introns in genes, however, varies greatly among animals. While...

UT Southwestern researchers develop screening test for cells that activate immune system

...hich compounds activate immune-response cells that hold promise for future cancer-fighting vaccines. The new screening technique can scan thousands and even millions of compounds to identify those that activate dendritic cells, which are on constant recon patrol throughout the body to scout out cancerous...

Study provides insight into cellular defenses against genetic mutation

... the human body is encoded in genes, many of which hold the information necessary for the building of one or more proteins. Gene expression is the process by which information stored in genes is coverted into proteins that make up the body's structures and carry out its functions. While genetic instructio...

Scientists crack 40-year-old DNA puzzle and point to 'hot soup' at the origin of life

...o acids - glutamine and asparagine - are unable to hold their shape in high temperatures, this suggests that heat prevented them from being acquired by the code at some point in the past. One possible reason for this is that the Last Universal Common Ancestor (LUCA), which evolved into all life on earth,...

...uce new fungicides or new resistant rice plants to hold this pathogen at bay. However, rice blast fungus is able to quickly evolve new tricks to tackle rice plants, apparently because the fungus and the grain developed side by side over centuries, according to genetic experts. To overcome the fungus' wile...

Newly recognized gene mutation may reduce seeds, resurrect plants

...tated plant that seems to return from the dead may hold the secret to how some flora protect their progeny during yield-limiting drought and other stresses, according to Purdue University scientists whose study of the plant led to discovery of a gene. The gene, called RESURRECTION1 (RST1), has revealed a...
