| DNA sequencing helps identify cancer cells for immune system attack Posted: 08 Feb 2012 12:23 PM PST DNA sequences from tumor cells can be used to direct the immune system to attack cancer, according to scientists. The immune system relies on an intricate network of alarm bells, targets and safety brakes to determine when and what to attack. The new results suggest that scientists may now be able to combine DNA sequencing data with their knowledge of the triggers and targets that set off immune alarms to more precisely develop vaccines and other immunotherapies for cancer.  |
| Transformational fruit fly genome catalog completed Posted: 08 Feb 2012 12:23 PM PST Scientists searching for the genomics version of the holy grail – more insight into predicting how an animal's genes affect physical or behavioral traits – now have a reference manual that should speed gene discoveries in everything from pest control to personalized medicine.  |
| New 'cell assay on a chip:' Solid results from simple means Posted: 08 Feb 2012 10:28 AM PST A research engineer combined a glass slide, plastic sheets and double-sided tape to build a "diffusion-based gradient generator", a tool to rapidly assess how changing concentrations of specific chemicals affect living cells.  |
| Timing capability added to living cell sensors Posted: 08 Feb 2012 10:27 AM PST Individual cells modified to act as sensors using fluorescence are already useful tools in biochemistry, but now they can add good timing to their resume.  |
| Scientists develop biological computer to encrypt and decipher images Posted: 07 Feb 2012 05:28 PM PST Scientists have developed a "biological computer" made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips.  |
| Entire genome of extinct human decoded from fossil Posted: 07 Feb 2012 10:36 AM PST Scientists have completed the genome sequence of a Denisovan, a representative of an Asian group of extinct humans related to Neanderthals.  |
| Sharp images from the living mouse brain Posted: 06 Feb 2012 09:24 AM PST Scientists have for the first time made finest details of nerve cells in the brain of a living mouse visible.  |
