Super-effective 'jumping gene' created
...e in establishing the evolutionary shifts that now distinguish mice from men, and that even now their DNA affects how other genes are used. Both mice and men share jumping genes known as L1 retrotransposons, some of which are "young" and still active, but most of which are "rusting hulks" that account for mor......ite shells absorb contaminants. "The problem is to distinguish between material absorbed from the environment and unique sequences from these organisms." Av-Gay too will say nothing about what his studies have revealed. "The story seems to be gearing towards the idea that these are not bacteria, but maybe a new ...Pancreatic cancer blood test & gene studies show promise
...tients through a slender needle, they were able to distinguish the two conditions. More research is needed, but the technique could lead to new ways of telling pancreatitis from cancer without the need for surgery. All three announcements were made at the Digestive Diseases Week meeting here. "We're definitely ...Stem cells toward sperm cells and back again
... in the testis because we can detect proteins that distinguish them, and we know exactly where the stem cells are supposed to be," says Matunis. "In fruit flies, we also know the signal that keeps the stem cells in their primitive state, and we can turn it off and on. We don't have any of this information for pe...Bird's eye views earth's magnetic lines

To distinguish between the photoreceptor and magnetite mechanisms, European robins orienting to the north during the Spring migration were exposed to low-level radio frequencies predicted to disrupt the energy states of any light-absorbing molecules involved in sen...Surprising 'ultra-conserved' regions discovered in human genome
... genomes that are often used in genetic testing to distinguish one human from another. They found 20-fold fewer SNPs in the conserved regions than would have occurred if SNPs were randomly sprinkled throughout the genome. Interestingly, the rate of change that has occurred in these regions when compared with o...Scripps scientists look deep inside sharks and their high-performance swimming system
...at respect." The authors say these characteristics distinguish lamnid sharks and tunas from virtually all other fish and arose independently in each, most likely the result of evolutionary selection for fast and continuous locomotion. Shadwick says in this respect lamnids and tunas are more like each other than ...Human brain works heavy statistics learning language

People were able to distinguish the regularity of certain consonant relationships and use them to properly divide the stream of sounds into words even though the statistics involved were at least as complicated as the earlier test that was universally failed. Even switching the rol...Setting the gene expression base-line for breast cancer research
.... Microarray analyses have previously been used to distinguish between sub-classes of breast tumors based on the differential expression of many hundreds of genes. For example, one sub-class of tumor was identified as 'basal-like' because the tumors expressed a series of genes thought to be expressed in myoepith...Kiratisin wins 2004 Dade MicroScan Young Investigator Award

Moreover, more-sensitive molecular methods for identifying these organisms are not readily available outside of specia......dy. But in water-logged kidneys, the image may not distinguish between different functional parts. Now, Prof. Hadassa Degani of the Biological Regulation Department and her lab team have found a way to see into the kidneys using magnetic resonance imaging (MRI) that scans sodium ions rather than water. ...SAGE-acious prediction of thyroid carcinoma
