In a new study, infants averaging six months of age who exhibited positional plagiocephaly (flat head syndrome) had lower scores than typical infants in observational tests used to evaluate cognitive and motor development. Positional or deformational plagiocephaly may occur when external forces shape an infant's skull while it is still soft and malleable, such as extended time spent lying on a hard surface or in one position.

A puff of air was used to spur the flies into flapping their wings, while electrodes measured the activity of the marked neurons and high-speed digital cameras simultaneously recorded the flies' behavior.
The UC San Diego bioengineers published the new findings in the January 25, 2010 issue of the journal ASN NEURO. "We didn't generate these waves artificially. Amyloid beta fragments induced the waves spontaneously, and that raises some interesting questions about the pathophysiology of Alzheimer's disease and how astrocytes may be involved," said bioengineering professor Gabriel Silva from the UC San Diego Jacobs School of Engineering and the senior author on the paper.
The chances of suffering a stroke are linked to the presence of a certain type of antibody in the immune system, a new study from Karolinska Institutet shows. The researchers hope to be able to develop a vaccine that can mobilise the body's own defence against arteriosclerosis and stroke.
The research group, which was led by Professor Johan Frostegård, has previously demonstrated that high levels of a certain type of antibody (anti-PC) in the immune defence are linked to a reduced risk of arteriosclerosis, a common cause of thrombosis and myocardial infarction.
MADISON, WI, February 11, 2010-Academic programs and courses have increased in recent years for sustainable agriculture, organic farming, and agroecology. In a recent study published in the 2010 volume of the Journal of Natural Resources and Life Sciences Education, researchers from Cornell University and North Carolina State University sought to bring hands-on learning activities and experiential learning, which are often a part of for-credit coursework, to employment settings.
New Rochelle, NY, February 11, 2010—Posttraumatic stress disorder (PTSD) threatens to overload healthcare and social support systems worldwide as the number of cases rises and existing treatments are not sufficiently effective. New approaches to treatment are relying on technology, such as virtual reality, to alleviate the psychologically damaging effects of PTSD, and these innovative solutions are explored in a special issue of Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal published by Mary Ann Liebert, Inc.
CHICAGO --- Why do people with fragile X syndrome, a genetic defect that is the best-known cause of autism and inherited mental retardation, recoil from hugs and physical touch – even from their parents?
Los Angeles, London, New Delhi, Singapore and Washington DC (February 11, 2010) — While many adults consider a chubby baby healthy, too many plump infants grow up to be obese teens, saddling them with Type-2 diabetes, elevated cholesterol and high blood pressure, according to an article published this month in the journal Clinical Pediatrics (published by SAGE).
The research suggests that the "tipping point" in obesity often occurs before two years of age, and sometimes as early as three months, when the child is learning how much and what to eat.
AUGUSTA, Ga. – Medical College of Georgia researchers are conducting the first FDA-approved clinical trial to determine whether an infusion of stem cells from umbilical cord blood can improve the quality of life for children with cerebral palsy.
The study will include 40 children age 2-12 whose parents have stored cord blood at the Cord Blood Registry in Tucson, Ariz.
Scientists are a step closer to understanding how abnormalities in brain development might lead to autism and behavioural disorders.
Research into Fragile X Syndrome – a genetic condition that is the leading known cause of autism – has discovered that critical phases in the brain's development may be mistimed in people with the condition.
An air of defeatism exists within the medical profession about chronic fatigue syndrome that is undermining evidence that it can be treated, argue three senior doctors in this week's BMJ.
Stuttering may be the result of a glitch in the day-to-day process by which cellular components in key regions of the brain are broken down and recycled, says a study in the Feb. 10 Online First issue of the New England Journal of Medicine. The study, led by researchers at the National Institute on Deafness and Other Communication Disorders (NIDCD), part of the National Institutes of Health, has identified three genes as a source of stuttering in volunteers in Pakistan, the United States, and England.
WHITE PLAINS, N.Y., Feb. 11, 2010 – Family history, infection and stress all may play a role in raising a woman's risk of having a premature baby – but they don't fully explain why some women give birth too soon and others don't, according to a review article published today in the New England Journal of Medicine.
New research provides insight into why fragile X syndrome, the most common known cause of autism and mental retardation, is associated with an extreme hypersensitivity to sounds, touch, smells, and visual stimuli that causes sensory overload and results in social withdrawal, hyperarousal, and anxiety. The study, published by Cell Press in the February 11 issue of the journal Neuron, uncovers a previously unknown developmental delay in a critical brain circuit that processes sensory information in a mouse model of fragile X syndrome.
New research provides fascinating insight into brain changes that might underlie alterations in spiritual and religious attitudes. The study, published by Cell Press in the February 11 issue of the journal Neuron, explores the neural basis of spirituality by studying patients before and after surgery to remove a brain tumor.
