How The Human Brain Adapts To Injury And How Individuals Can Train Their Brains To Handle Injuries More Efficiently
Date: Jan-18-2013For the first time, scientists at Carnegie Mellon University's Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury. The research, published in Cerebral Cortex, shows that when one brain area loses functionality, a "back-up" team of secondary brain areas immediately activates, replacing not only the unavailable area but also its confederates...
Major Role Played By Genetics In Elementary School Victimization
Date: Jan-18-2013Genetics plays a major role in peer rejection and victimization in early elementary school, according to a study recently published on the website of the journal Child Development by a team directed by Dr. Michel Boivin, a research professor at Université Laval's School of Psychology. To come to this conclusion, Boivin and his team tested over 800 twins at three time points: when they were in kindergarten, Grade 1, and Grade 4...
Lessons From The Past: Dickens Used Literature To Showcase Discrimination Against The Disabled
Date: Jan-18-2013Charles Dickens' tales are filled with immortal characters - think of A Christmas Carol's Scrooge and Great Expectations' Miss Havisham. But more than whims of literary invention, his characters and plots often deal with the difficult social realities of Victorian England. His portrayal of the disabled - both in terms of medicine and the social discrimination they faced - is no exception. "Social attitudes towards the disabled can often be traced through art, from ancient times through today," explains Prof...
A New Culprit For Epileptic Seizures
Date: Jan-18-2013Epileptic seizures occur when neurons in the brain become excessively active. However, a new study from MIT neuroscientists suggests that some seizures may originate in non-neuronal cells known as glia, which were long believed to play a mere supporting role in brain function. In a study of fruit flies, the researchers identified a glial-cell mutation that makes the flies much more prone to epileptic seizures. Mutations in the gene, which influences glial cells' communication with neurons, appear to make neurons much more excitable...
Slower Growth Of Preterm Infants Linked To Altered Brain Development
Date: Jan-18-2013Preterm infants who grew more slowly as they approached what would have been their due dates also have slower development in an area of the brain called the cerebral cortex, report Canadian researchers in a new study published in Science Translational Medicine. The cerebral cortex is a two to four millimetre layer of cells that envelopes the top part of the brain and is involved in cognitive, behavioural, and motor processes. Researchers analyzed MRI brain scans of 95 preterm infants born eight to 16 weeks too early at BC Women's Hospital & Health Centre between 2006 and 2009...
FDA Reports Metal-on-Metal Hip Implants Cause Soft Tissue Damage
Date: Jan-18-2013For many years metal-on-metal hip devices have failed at surprisingly high rates and the question being asked remains: "Is there a lack of clinical benefits with metal-on-metal bearings?" Recent updated information from the FDA (U.S. Food and Drug Administration) claims that metal-on-mental hip implants can cause soft-tissue damage and pain, possibly leading to more surgery to replace the implant. Metal hip implants were created to be more sturdy than traditional implants, but instead have become a serious cause of worry following many user discomforts and safety problems...
The Spread Of Hospital-Acquired Bacteria Revealed By Computational Methods
Date: Jan-18-2013Scientists at the Academy of Finland's Centre of Excellence in Computational Inference Research have developed novel computational methods that have yielded essential knowledge of how hospital-acquired bacteria spread and develop. These new methods, based on randomised algorithms, make it possible to analyse extensive genomic data significantly faster and more efficiently than previously. By applying these results, it is possible to better follow hospital-acquired infections in the future, or even fight them in real time...
The Reality Of Racism: Claims Of "Post-Racial" Society And Other Denials Of Racism May Reflect Ignorance Of History
Date: Jan-18-2013New research suggests that commonly observed differences in how groups perceive racism may be explained by ignorance about - and even denial of - the extent of racism over the course of history. The research, conducted by psychological scientists at the University of Kansas and Texas A&M University, indicates that African Americans had more accurate knowledge of historically documented racism compared to European Americans. This difference in historical knowledge partially accounted for group differences in perceptions of racism, both at a systemic and an incident-specific level...
Body Language Conveys Intense Emotions Better Than The Face
Date: Jan-18-2013Be it triumph or crushing defeat, exhilaration or agony, body language more accurately conveys intense emotions, according to recent research that challenges the predominance of facial expressions as an indicator of how a person feels. Princeton University researchers report in the journal Science that facial expressions can be ambiguous and subjective when viewed independently. The researchers asked study participants to determine from photographs if people were experiencing feelings such as loss, victory or pain from facial expressions or body language alone, or from both...
Tumors Flourish In Inflammed Tissue; Readdition Of SPARC Reduces Inflammation And Stops Proliferation
Date: Jan-18-2013Body's ibuprofen, SPARC, reduces inflammation and thus bladder cancer development and metastasis Cancer researchers are increasingly aware that in addition to genetic mutations in a cancer itself, characteristics of the surrounding tissue can promote or suppress tumor growth. One of these important tissue characteristics is inflammation - most cancers prosper in and attach to inflamed tissue and so many cancers have developed ways to create it...
