Untangling the biological effects of blue light

Untangling the biological effects of blue light

Blue light can both set the mood and set in motion important biological responses. Researchers at the University of Pennsylvania’s School of Medicine and School of Arts and Sciences have teased apart the separate biological responses of the human eye to blue light, revealing an unexpected contest for control. Their work addresses the properties of melanopsin, a light-sensitive protein in the eye that establishes the rhythm of our day-night cycle and the familiar constriction of the pupil to bright light.

Measuring on ice: Researchers create ‘smart’ ice skating blade

Measuring on ice: Researchers create ‘smart’ ice skating blade

An ice skating blade that informs figure skaters of the stresses they are imposing on their joints has been developed by a group of researchers in the US. The small, lightweight device has been built to measure the force that a figure skater exerts on the ice when performing their repertoire of jumps and spins and could potentially be used by skaters and their trainers to avoid injuries, as well as inform the design of new skating boots Continue reading

Three people infected with Ebola predicted to fly from West Africa every month if no exit screening takes place

Three people infected with Ebola predicted to fly from West Africa every month if no exit screening takes place

Three Ebola-infected travellers are predicted to depart on an international flight every month from any of the three countries in West Africa currently experiencing widespread Ebola virus outbreaks (Guinea, Liberia, or Sierra Leone), if no exit screening were to take place, according to new modelling research published in The Lancet.

Three people infected with Ebola predicted to fly from West Africa every month if no exit screening takes place

Three Ebola-infected travellers are predicted to depart on an international flight every month from any of the three countries in West Africa currently experiencing widespread Ebola virus outbreaks (Guinea, Liberia, or Sierra Leone), if no exit screening were to take place, according to new modelling research published in The Lancet. Dr Kamran Khan at St Michael’s Hospital in Toronto, Canada, and colleagues analysed 2014 worldwide flight schedules and historic flight itineraries of passengers from 2013 to predict expected population movements out of Guinea, Liberia, and Sierra Leone. They also used WHO Ebola virus surveillance data to model the expected number of exported Ebola virus infections and to determine how useful air travel restrictions and airport departure and arrival screening might be in controlling the spread of the deadly virus Continue reading

Scientists restore hearing in noise-deafened mice, pointing way to new therapies

Scientists restore hearing in noise-deafened mice, pointing way to new therapies

Scientists have restored the hearing of mice partly deafened by noise, using advanced tools to boost the production of a key protein in their ears. By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research in humans that could improve treatment of hearing loss caused by noise exposure and normal aging Continue reading

By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research in humans that could improve treatment of hearing loss caused by noise exposure and normal aging. In a new paper in the online journal eLife , the team from the University of Michigan Medical School’s Kresge Hearing Research Institute and Harvard University report the results of their work to understand NT3′s role in the inner ear, and the impact of increased NT3 production on hearing after a noise exposure.

Siblings of children with autism can show signs at 18 months

Siblings of children with autism can show signs at 18 months

About 20% of younger siblings of children with Autism Spectrum Disorder (ASD) will develop the condition by age 3. A new study by Yale School of Medicine researchers has found that 57% of these younger siblings who later develop the condition already showed symptoms at age 18 months. Published in the October Journal of the American Academy of Child & Adolescent Psychiatry , this is the first large-scale, multi-site study aimed at identifying specific social-communicative behaviors that distinguish infants with ASD from their typically and atypically developing high-risk peers as early as 18 months of age Continue reading

New test scans all genes simultaneously to identify single mutation causing child’s rare genetic disease

New test scans all genes simultaneously to identify single mutation causing child’s rare genetic disease

Audrey Lapidus adored her baby’s sunny smile and irresistible dimples, but grew worried when Calvin did not roll over or crawl by 10 months and suffered chronic digestive problems. Four neurologists dismissed his symptoms and a battery of tests proved inconclusive Continue reading

Women driven by status, wealth rather than wanting babies, study suggests

Women driven by status, wealth rather than wanting babies, study suggests

A new study suggests that women are more driven to seek wealth and status than they are to reproduce. The research by Oxford University and Sheffield University says although low fertility may seem to go against traditional ideas about evolutionary success, a woman will delay and reduce her fertility if it brings her opportunities for higher status. The findings are based on interviews with 9,000 women in Mongolia, a country that underwent a sudden transition from a Soviet-style state to mass privatization. Continue reading
