| New model to design better flu shots proposed Posted: 22 Dec 2011 12:20 PM PST The flu shot, typically the first line of defense against seasonal influenza, could better treat the US population, thanks to new research.  |
| How bacteria fight fluoride in toothpaste and in nature Posted: 22 Dec 2011 11:24 AM PST Researchers have uncovered the molecular tricks used by bacteria to fight the effects of fluoride, which is commonly used in toothpaste and mouthwash to combat tooth decay.  |
| Long intervening non-coding RNAs play pivotal roles in brain development Posted: 22 Dec 2011 10:33 AM PST Scientists have identified conserved, long intervening non-coding RNAs that play key roles during brain development in zebrafish, and went on to show that the human versions of these RNAs can substitute for the zebrafish lincRNAs. Until now, lincRNAs have been studied primarily in cell lines rather than at the organismal level, which has precluded research into how lincRNAs affect growth and development.  |
| Posted: 22 Dec 2011 10:33 AM PST Life is complicated enough, so you can forgive the pioneers of DNA biology for glossing over transcriptional elongation control by RNA polymerase II, the quick and seemingly bulletproof penultimate step in the process that copies the information encoded in our DNA into protein-making instructions carried by messenger RNA. Researchers now not only add a new layer, but a whole new dimension to transcriptional elongation control with evidence that for each class of genes transcribed by RNA polymerase II (Pol II), there exists a specific class of elongation factors.  |
| Posted: 22 Dec 2011 07:31 AM PST Researchers have uncovered what cells respond to anesthesia in an organism known as the C. elegans, according to a new study.  |
| Possible cure for leukemia found in fish oil Posted: 22 Dec 2011 07:31 AM PST A compound produced from fish oil that appears to target leukemia stem cells could lead to a cure for the disease, according to researchers.  |
| Severe congenital disorder successfully treated in a mouse model for the first time Posted: 22 Dec 2011 07:30 AM PST Using a mouse model, researchers have for the first time successfully treated a severe congenital disorder in which sugar metabolism is disturbed. Scientists demonstrated that if female mice are given mannose with their drinking water prior to mating and during pregnancy, their offspring will develop normally even if they carry the genetic mutation for the congenital disorder.  |
| Brain size may predict risk for early Alzheimer's disease Posted: 21 Dec 2011 06:12 PM PST New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.  |
| Crucial advances in 'brain reading' demonstrated Posted: 21 Dec 2011 11:07 AM PST A new study demonstrates several crucial advances in "brain reading" or "brain decoding" using computerized machine learning methods. Researchers classified data taken from people being scanned while watching videos meant to induce nicotine cravings and detected whether people were watching and resisting cravings, indulging in them, or watching videos that were unrelated to smoking or cravings.  |
| Myths and truths of obesity and pregnancy Posted: 21 Dec 2011 07:58 AM PST Ironically, despite excessive caloric intake, many obese women are deficient in vitamins vital to a healthy pregnancy. This and other startling statistics abound when obesity and pregnancy collide. Together, they present a unique set of challenges that women and their doctors must tackle in order to achieve the best possible outcome for mom and baby.  |
| Balancing the womb: New research hopes to explain premature births and failed inductions of labour Posted: 21 Dec 2011 07:57 AM PST New research hopes to explain premature births and failed inductions of labor.  |
| Posted: 21 Dec 2011 07:56 AM PST By researching fruit flies, neuroscientists were able to gain a better understanding of a meaningful mechanism of neuronal communication. They demonstrated the importance of a specific protein for signal transmission between nerve cells. This is of high significance as certain people with autism - a functional development disturbances of the brain - suffer from genetic defects in this protein. Therefore the findings could improve the possibility of treating this disease more effectively.  |
| Severe sepsis can lead to impairment of immune system, study suggests Posted: 20 Dec 2011 02:26 PM PST An analysis of lung and spleen tissue from patients who died of sepsis revealed certain biochemical, cellular and histological findings that were consistent with immunosuppression, according to a new study.  |
