Biological mechanism that plays key role in early-onset dementia identified

ScienceDaily (Oct. 8, 2012) — Using animal models, scientists at the Gladstone Institutes have discovered how a protein deficiency may be linked to frontotemporal dementia (FTD) — a form of early-onset dementia that is similar to Alzheimer’s disease Continue reading

Smallest and fastest-known RNA switches provide new drug targets

ScienceDaily (Oct. 7, 2012) — A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting structures are prime targets for the development of new antiviral and antibiotic drugs Continue reading

‘Stem cell hope’ for deaf people

‘Stem cell hope’ for deaf people

12 September 2012 Last updated at 13:00 ET By James Gallagher Health and science reporter, BBC News UK researchers say they have taken a huge step forward in treating deafness after stem cells were used to restore hearing in animals for the first time. Hearing partially improved when nerves in the ear, which pass sounds into the brain, were rebuilt in gerbils – a UK study in the journal Nature reports. 1 Getting the same improvement in people would be a shift from being unable to hear traffic to hearing a conversation Continue reading

Most mutations come from dad: New insights into age, height and sex reshape views of human evolution

ScienceDaily (Aug. 23, 2012) — Humans inherit more than three times as many mutations from their fathers as from their mothers, and mutation rates increase with the father’s age but not the mother’s, researchers have found in the largest study of human genetic mutations to date. The study, based on the DNA of around 85,000 Icelanders, also calculates the rate of human mutation at high resolution, providing estimates of when human ancestors diverged from nonhuman primates Continue reading
