Contrary to popular belief, some very smart, accomplished people cannot read well. This unexpected difficulty in reading in relation to intelligence, education and professional status is called dyslexia, and researchers at Yale School of Medicine and University of California Davis, have presented new data that explain how otherwise bright and intelligent people struggle to read. http://www.physorg.com/news180283007.html Medicine & Health Thu, 17 Dec 2009 15:30:01 EST news180283007 (PhysOrg.com) -- The American coot is a drab, seemingly unremarkable marsh bird common throughout North America. But its reproductive life is full of deception and violence. http://www.physorg.com/news180193135.html Biology Wed, 16 Dec 2009 14:10:04 EST news180193135 We've all been in situations before where we get so frustrated or angry about something, we will lash out at someone without thinking. This lashing out - reactive negativity - happens when we can't control our emotions. Luckily, we are usually pretty good at self-regulating and controlling our emotions and behaviors. Working memory is crucial for cognitive control of emotions: It allows us to consider information we have and reason quickly when deciding what to do as opposed to reacting automatically, without thinking, to something. http://www.physorg.com/news179060311.html Medicine & Health Thu, 03 Dec 2009 10:59:53 EST news179060311 The Georgia Institute of Technology has been awarded a U.S. Air Force Center of Excellence to design nanostructures for energy harvesting and adaptive materials, and to develop tools to optimize critical cognitive processes of the modern warfighter. http://www.physorg.com/news178902408.html Nanotechnology Tue, 01 Dec 2009 15:30:03 EST news178902408 (PhysOrg.com) -- What, exactly, distinguishes humans from apes? It`s certainly more than just our genes, renowned anthropologist Sarah Blaffer Hrdy told a Harvard audience recently (Nov. 18). http://www.physorg.com/news178820796.html Biology Mon, 30 Nov 2009 22:30:01 EST news178820796 In a new study, the amount of television viewed by many young children in child care settings doubles the previous estimates of early childhood screen time, with those in home-based settings watching significantly more on average than those in center-based daycares. This study is the first to examine screen time in child care settings in more than 20 years. http://www.physorg.com/news178178418.html Medicine & Health Mon, 23 Nov 2009 06:00:49 EST news178178418 (PhysOrg.com) -- A gene associated with longevity in roundworms and humans has been shown to affect the function of stem cells that generate new neurons in the adult brain, according to researchers at the Stanford University School of Medicine. The study in mice suggests that the gene may play an important role in maintaining cognitive function during aging. http://www.physorg.com/news176651173.html Medicine & Health Thu, 05 Nov 2009 13:48:34 EST news176651173 (PhysOrg.com) -- UA graduate student Rita Law's study to evaluate long-term effects of marital status and church attendance is among very few that have considered such a correlation. http://www.physorg.com/news174145884.html Medicine & Health Wed, 07 Oct 2009 15:10:01 EST news174145884 (PhysOrg.com) -- A study of female monkeys' grooming habits provides new clues about the way humans socialise. New research reveals a link between the size of the neocortex in the brain, responsible for higher-level thinking, and the size of grooming clusters that monkeys belong to. http://www.physorg.com/news173541242.html Biology Wed, 30 Sep 2009 14:54:32 EST news173541242 Two new studies explore how discipline changes during childhood and adolescence, and what family factors affect those changes. They conclude that when parents use physical discipline through childhood, their children experience more behavior problems in adolescence. http://www.physorg.com/news172215316.html Medicine & Health Tue, 15 Sep 2009 06:50:02 EST news172215316 (PhysOrg.com) -- A Queensland University of Technology researcher is looking for volunteers to take part in a study aimed at making contemporary appliances such as dvd players and mobile phones more usable for the elderly. http://www.physorg.com/news171610284.html Technology Tue, 08 Sep 2009 06:32:24 EST news171610284 (PhysOrg.com) -- Sometimes inspiration comes from the strangest of places. For Sheree Kwong See, it happened during a testing session with a subject while conducting a study on language and cognitive changes in the elderly. Kwong See was explaining the test to the research participant who reacted to the instructions in a quite unexpected manner. http://www.physorg.com/news169912987.html Other Sciences Wed, 19 Aug 2009 15:20:01 EST news169912987 Rats fed a high-fat diet show a stark reduction in their physical endurance and a decline in their cognitive ability after just nine days, a study by Oxford University researchers has shown. http://www.physorg.com/news169209397.html Medicine & Health Tue, 11 Aug 2009 12:00:04 EST news169209397 (PhysOrg.com) -- New experiments by Oxford University scientists reveal that New Caledonian crows can spontaneously use up to three tools in the correct sequence to achieve a goal, something never before observed in non-human animals without explicit training. http://www.physorg.com/news168701856.html Biology Wed, 05 Aug 2009 14:38:26 EST news168701856 People who are rewarded for making correct decisions learn quickly. While the "carrot" approach may produce favourable results, little is understood about how rewards facilitate the learning process. http://www.physorg.com/news167988751.html Biology Tue, 28 Jul 2009 08:50:01 EST news167988751 Anemia in very elderly people aged 85 and older appears to be associated with an increased risk of death, according to a new study in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/press/cmaj090040.pdf. http://www.physorg.com/news167919875.html Medicine & Health Mon, 27 Jul 2009 13:25:03 EST news167919875 Eating disorders are frequently seen as psychological or societal diseases, but do they have an underlying biological cause? A new study shows that the levels of a brain protein differ between healthy and anorexic women. http://www.physorg.com/news164973925.html Medicine & Health Tue, 23 Jun 2009 11:20:01 EST news164973925 Babies of East Asian and South Asian descent are between two and three times more likely to be misclassified as underweight at birth when compared to their Canadian counterparts, according to a study led by St. Michael's Hospital physician Dr. Joel Ray. Dr. Ray and a team of researchers, who developed the first-ever sex-specific birth weight curves for these ethnic groups, suggest the need to consider differences across ethnic groups to reduce parental stress and use of health-care resources associated with labelling an infant as underweight, or "small for gestational age" at birth. http://www.physorg.com/news162568152.html Medicine & Health Tue, 26 May 2009 14:49:41 EST news162568152 A global analysis of brain proteins over a 10-week period in a mouse model of Huntington Disease has revealed some new insights into this complex neurodegenerative disorder. For example, profound changes (comparable to those seen in late-stage HD) actually occur well before any disease symptoms show up, and most of the changes are confined to a specific stage during disease progression. These findings should aid in determining the optimal times for therapies that aim to treat or cure this disease. http://www.physorg.com/news159115703.html Medicine & Health Thu, 16 Apr 2009 15:48:50 EST news159115703 A collaborative study led by researchers at the Montreal Neurological Institute (MNI), McGill University has demonstrated a positive link between cognitive ability and cortical thickness in the brains of healthy 6 to 18 year olds. The correlation is evident in regions that integrate information from different parts of the brain. The imaging study published this week in a special issue of scientific journal Intelligence is the largest and most comprehensive of its kind with a representative sample of healthy children and adolescents. http://www.physorg.com/news157210821.html Medicine & Health Wed, 25 Mar 2009 14:40:45 EST news157210821 A new study indicates that some aspects of peoples' cognitive skills - such as the ability to make rapid comparisons, remember unrelated information and detect relationships - peak at about the age of 22, and then begin a slow decline starting around age 27. http://www.physorg.com/news156751524.html Medicine & Health Fri, 20 Mar 2009 07:06:10 EST news156751524 Children born extremely prematurely are at high risk of developing learning difficulties by the time they reach the age of 11. http://www.physorg.com/news156016378.html Medicine & Health Wed, 11 Mar 2009 18:54:05 EST news156016378 (PhysOrg.com) -- Neuroscientists at the California Institute of Technology (Caltech) have conducted the most comprehensive brain mapping to date of the cognitive abilities measured by the Wechsler Adult Intelligence Scale (WAIS), the most widely used intelligence test in the world. The results offer new insight into how the various factors that comprise an "intelligence quotient" (IQ) score depend on particular regions of the brain. http://www.physorg.com/news155994901.html Medicine & Health Wed, 11 Mar 2009 12:55:25 EST news155994901 Loss of thinking power is a fear shared by many aging baby boomers.
