Autism Problems Explained In New Research
New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties.Using functional magnetic resonance imaging technology (fMRI) the Florey scientists have shown that children with autism have less activation in the deep parts of the brain responsible for executive function (attention, reasoning and problem solving). New Findings Lead Researchers To Question Basic Assumptions Of Fisheri
Biologists speaking at a symposium in Washington, D.C., last week warned that fundamental assumptions underlying current fisheries management practices may be wrong, resulting in management decisions that threaten the future supply of fish and the long-term survival of some fish populations. Vitamin E's Lack Of Heart Benefit Linked To Dosage
The reported failure of vitamin E to prevent heart attacks may be due to underdosing, according to a new study. The findings suggest that these earlier studies all had a fundamental flaw -- the doses used weren't high enough to have a significant antioxidant effect. In fact, no studies have ever conclusively demonstrated the dose at which vitamin E can be considered an antioxidant drug, the researchers report. High-sugar Diet Pushing Some Latino Kids Toward Type 2 Diabetes
Overweight Latino children who consume lots of sugar-especially in sugary drinks-show signs of beta cell decline, a precursor of type 2 diabetes. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Planning For 2020: Increasing Elderly Population Poses Huge Challenges
Huge challenges face healthcare professionals and policy makers in planning for, and providing cancer care over the next decade or so. According to researchers, a greater number of elderly people with cancer will need care, current inappropriate ageist attitudes towards the elderly must cease, and advances are being made to ensure patients comply with prescribed treatment. Bacteria Take The Path Of Least Resistance
Researchers have reported new information about how certain bacteria propel themselves from one place to another. Insight into bacterial micro-movement will benefit scientists and engineers developing nano-scale mechanical devices that may one day push fluids and transport molecules without the aid of pumps or electrical charges. Scientists Create Digital Bacteria To Forge Advances In Biomedical Res
Scientists at the University of Chicago and Argonne National Laboratory have constructed a computer simulation that allows them to study the relationship between biochemical fluctuations within a single cell and the cell's behavior as it interacts with other cells and its environment. Nigerian Film Industry Mixes Digital Tech, Homegrown Scripts
The Nigerian film industry, known informally as Nollywood, produces thousands of films a year using low-budget digital video cameras and home computers. Two new films document the industry. Brain Circuits Used In Sensation Of Touch Identified
The ability to tactually recognize fine spatial details, such as the raised dots used in braille, is especially important to those who are blind. With that in mind, a team of researchers has identified the neural circuitry that facilitates spatial discrimination through touch. Understanding this circuitry may lead to the creation of sensory-substitution devices, such as tactile maps for the visually impaired.
