Class of RNA molecules protects germ cells from damage

Class of RNA molecules protects germ cells from damage

ScienceDaily (Nov. 15, 2012) — Passing one’s genes on to the next generation is a mark of evolutionary success. So it makes sense that the body would work to ensure that the genes the next generation inherits are exact replicas of the originals Continue reading

Cancer therapy: Nanokey opens tumors to attack

ScienceDaily (Nov. 14, 2012) — There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. Continue reading

Family tree stops MRSA outbreak

Family tree stops MRSA outbreak

13 November 2012 Last updated at 20:03 ET By James Gallagher Health and science reporter, BBC News An outbreak of the hospital superbug MRSA has been brought to an end by UK doctors cracking the bacterium’s genetic code. It led to them finding one member of staff at Rosie Hospital, in Cambridge, who may have unwittingly carried and spread the infection. They say it is the first time rapid genetic testing has been used to track and then stop an outbreak Continue reading

New type of bacterial protection found within cells: Novel immune system response to infections discovered

New type of bacterial protection found within cells: Novel immune system response to infections discovered

ScienceDaily (Nov. 13, 2012) — UC Irvine biologists have discovered that fats within cells store a class of proteins with potent antibacterial activity, revealing a previously unknown type of immune system response that targets and kills bacterial infections. Continue reading

‘Calm down’ genes treat epilepsy

‘Calm down’ genes treat epilepsy

12 November 2012 Last updated at 12:11 ET By James Gallagher Health and science reporter, BBC News Adding “calm down” genes to hyperactive brain cells has completely cured rats of epilepsy for the first time, say UK researchers. They believe their approach could help people who cannot control their seizures with drugs. Continue reading

New form of brain plasticity: How social isolation disrupts myelin production

ScienceDaily (Nov. 11, 2012) — Animals that are socially isolated for prolonged periods make less myelin in the region of the brain responsible for complex emotional and cognitive behavior, researchers at the University at Buffalo and Mt Continue reading

Antibiotics disrupt gut flora in infants: Recovery still incomplete after eight weeks

Antibiotics disrupt gut flora in infants: Recovery still incomplete after eight weeks

ScienceDaily (Nov. 8, 2012) — Eight weeks after antibiotic treatment of infants, the diversity of gastrointestinal flora remained diminished, although the number of individual bacteria was back to normal, according to a paper in the November 2012 issue of the journal Antimicrobial Agents and Chemotherapy . Additionally, the potentially disease-causing Proteobacteria were now the dominant population in the treated infants Continue reading

New portable device enables RNA detection from ultra-small sample in only 20 minutes

New portable device enables RNA detection from ultra-small sample in only 20 minutes

ScienceDaily (Nov. 7, 2012) — A new power-free microfluidic chip developed by researchers at the RIKEN Advanced Science Institute (ASI) enables detection of microRNA from extremely small sample volume in only 20 minutes. By drastically reducing the time and quantity of sample required for detection, the chip lays the groundwork for early-stage point-of-care diagnosis of diseases such as cancer and Alzheimer’s Continue reading
