Tiny genetic differences have huge consequences: McGill researchers
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.
Virtual biopsy cuts out need for diagnostic surgery
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.
Weird water: Discovery challenges long-held beliefs about water's special properties
Technology used to measure body composition in gyms could soon be used to help diagnose cancers without patients going under the knife.
World-leading journal publishes special issue on UN/GA
A multi-institutional team was surprised to find a highly simplified model molecule that behaves in much the same way as water, a discovery that upends long-held beliefs about what makes water so special.
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
A tricky tumor virus
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.
Altering brain's lipid metabolism reduces Alzheimer's plaques in mice
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...
Alzheimer's molecule is a smart speed bump on the nerve-cell transport highway
Increasing levels of a protein that helps the brain use cholesterol may slow the development of Alzheimer's disease changes in the brain, according to researchers studying a mouse model of the disease at Washington University School of Medicine in St. Louis.
Annual bone fracture rate almost 4 percent and double previous estimates
Researchers at the University of Pennsylvania School of Medicine discovered that proteins carrying chemical cargo in nerve cells react differently when exposed to the tau protein, which plays an important role in Alzheimer's disease.
Battling potential disease outbreaks online
The annual bone fracture rate in England is just short of 4 percent of the population, which is more than double previous estimates, suggests a study in the Journal of Epidemiology and Community Health.
California flood risks are 'disaster waiting to happen,' say University of Maryland engineers
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.
Cancer stem cell marker also drives transcription in normal cells
While flooding in California's Central Valley is "the next big disaster waiting to happen," critical water-related infrastructure issues confront almost every community across the country, according to engineers at the University of Maryland's Clark School of Engineering in separate reports to California officials and in the journal Science.
Chromosomal abnormalities play substantial role in autism
New research links the recently discovered function of a multi-faceted transcriptional complex to control of gene expression in both normal cells and cancer stem cells...
Consuming extra virgin olive oil helps to combat degenerative diseases such as cancer
Genome-wide scans of families affected by autism spectrum disorder have revealed new evidence that previously unknown chromosomal abnormalities have a substantial role in the prevalent developmental disorder, according to...
Contact lenses with circuits, lights a possible platform for superhuman vision
Researchers from the University of Granada have for the first time analyzed the antioxidant properties of olive oil, a product rich in polyphenols. The Environmental, Biochemical and Nutritional Analytical-Control Research Group had already carried out the polyphenolic characterization of food products, such as honey and beer.
Deep-ocean researchers target tsunami zone near Japan
Achieving superhuman vision like the Bionic Woman's could be as easy as popping in a contact lens. UW engineers have for the first time combined a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.
Diet and lifestyle critical to recovery, says study
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
Diet and lifestyle may play a much more significant role in a person's ability to respond favorably to certain drugs, including some cancer therapies, than previously understood, say scientists.
Discovery cuts cost of next generation optical fibers
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.
Discovery major step forward in treating leukemia
Scientists have discovered a way of speeding up the production of hollow-core optical fibers -- a new generation of optical fibers that could lead to faster and more powerful computing and telecommunications technologies.
Discovery of 'creator' gene for cerebral cortex points to potential stem cell treatments
Researchers at the University of East Anglia have discovered for the first time a pathway that makes cancerous leukemia cells resistant to treatment.
Discovery opens door to 'personalized' asthma therapy
University of California-Irvine researchers have identified a gene that is specifically responsible for generating the cerebral cortex, a finding that could lead to stem cell therapies to treat brain injuries and diseases such as stroke and Alzheimer's.
Do today's young people really think they are so extraordinary?
Applying state-of-the-art protein screening techniques to samples taken from 84 asthmatic volunteers, researchers have made the first proteomic identification of different subtypes of asthma.
Engineered mice provide insight into Alzheimer's disease
An article appearing in the February issue of Psychological Science, a journal of the Association for Psychological Science, found no evidence that today's young people have inflated impressions of themselves compared to the youth of previous generations.
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...
