The human brain: Detective of auditory and visual change

The human brain is capable of detecting the slightest visual and auditory changes. Several studies have indicated, however, that even a small span of time in between pre- and post-change images can disturb the brain's ability to detect visual discrepancies. In a recent study, psychologists assessed the effect of time gaps on change detection in audition.

Tiny genetic differences have huge consequences: McGill researchers

A study led by McGill University researchers has demonstrated that small differences between individuals at the DNA level can lead to dramatic differences in the way genes produce proteins. These, in turn, are responsible for the vast array of differences in physical characteristics between individuals.

World-leading journal publishes special issue on UN/GA

The special issue of the journal Environmental Policy and Law is the first report on all documents related to environment and sustainable development discussed in the 62nd session of the UN General Assembly. The priorities of the session included: Climate change, financing for development, achievement of the Millennium Development Goals, counter-terrorism and the reform agenda to renew the...


'Nonlinear' ecosystem response points to environmental solutions

The preservation of coastal ecosystem services such as clean water, storm buffers or fisheries protection does not have to be an all-or-nothing approach, a new study indicates, and a better understanding of how ecosystems actually respond to protection efforts in a "nonlinear" fashion could help lead the way out of environmental-versus-economic gridlock.

A tricky tumor virus

Viruses use many tricks to gain control over their host cells and to reprogram them to their own advantage. Dr. Arnd Kieser and his colleagues of the Department of Gene Vectors of the Helmholtz Zentrum Munich, Germany, were able to show in a recent publication in PLoS Biology by which mechanism Epstein-Barr virus exploits a signal protein of its host cell, which normally mediates programmed cell...

Battling potential disease outbreaks online

Researchers from the Regenstrief Institute and the Indiana University School of Medicine have found that automated electronic medical laboratory reporting improves both the completeness and timeliness of disease surveillance, significantly bettering the odds of stopping the spread of disease. Their study appears in the February issue of the American Journal of Public Health.

Deep-ocean researchers target tsunami zone near Japan

Rice University Earth scientist Dale Sawyer and colleagues have reported the discovery of a strong variation in the tectonic stresses in a region of the Pacific Ocean notorious for generating devastating earthquakes and tsunamis in southeastern Japan. The results came from an eight-week expedition last fall at the Nankai Trough near Kobe, Japan. The team used a high-tech drill ship to probe deep...

Disability living allowance falls short for ethnic minorities

A study carried out by researchers at the Peninsula Medical School and the Institute of Child Health has revealed that families from an ethnic, non-English speaking background with a child with Down's syndrome do worse from the Disability Living Allowance system than families facing the same issues who come from a white, English-speaking background.

Engineered mice provide insight into Alzheimer's disease

One factor that determines an individual's risk of developing Alzheimer's disease is the version of the APOE gene that they carry. It has been hypothesized that increasing the amount of fat associated with apoE by overexpressing ABCA1 might decrease amyloid deposition in the brain, the hallmark of AD. Support for this hypothesis has now been generated in mice, suggesting that increasing the...
