Babies and toddlers learn by playing, not 'educational' TV

BOSTON -- The temptation to rely on media screens to entertain babies and toddlers is more appealing than ever, with screens surrounding families at home, in the car, and even at the grocery store. And there is no shortage of media products and programming targeted to little ones. But a new policy statement from the American Academy of Pediatrics (AAP) says there are better ways to help children learn at this critical age.

'Drunkorexia:' A recipe for disaster

COLUMBIA, Mo. – It is well known that eating disorders are common among teens and college students. Heavy alcohol consumption is another well-known unhealthy habit of this age group. A new study from the University of Missouri shows that when college students combine these two unhealthy habits, their long-term health may be affected. "Drunkorexia" is a new term coined by the media to describe the combination of disordered eating and heavy alcohol consumption.

Protecting the brain when energy runs low

Researchers from the Universities of Leeds, Edinburgh and Dundee have shed new light on the way that the brain protects itself from harm when 'running on empty.'

The findings could lead to new treatments for patients who are at risk of stroke because their energy supply from blood vessels feeding the brain has become compromised.

Many regions of the brain constantly consume as much energy as leg muscles during marathon running. Even when we are sleeping, the brain needs regular fuel.

Hypertension drugs could help people with Alzheimer's also

Within the next 20 years it is expected the number of people with Alzheimer's disease (AD) will double from its current figure of half a million to one million. A new study has looked at whether certain types of drugs used to treat high blood pressure, also called hypertension, might have beneficial effects in reducing the number of new cases of Alzheimer's disease each year.

KIBRA T allele: Gene variant leads to better memory

Carriers of the so-called KIBRA T allele have better memories than those who don't have this gene variant. This means we can reject the theory that the brain of a non-bearer compensates for this. This is shown by researchers from Umeå University in The Journal of Neuroscience.

Nourishing protein slows brain disease

A protein that promotes the growth of neurons and blood vessels appears to stop the progression of a genetic disease that causes degeneration of the cerebellum, according to new preclinical Northwestern Medicine research published in Nature Medicine.

The disease, spinocerebellar ataxia type 1, typically strikes people in their 30s and 40s and causes degeneration of the cerebellum, the part of the brain that helps coordinate movement. As the disease progresses over 10 to 20 years, patients eventually die from aspiration or infectious pneumonia.

Women, men and the bedroom

In the racy television hit show, Sex and the City, Carrie, one of the main characters tells her best girlfriends that "Men who are too good looking are never good in bed because they never had to be." This is just one of the many gender stereotypes that audiences were exposed to in this show. The show challenged many stereotypes about sex and gender and refrained from the gender caricatures that typify so much television fare.

Joslin study finds clue to birth defects in babies of mothers with diabetes

BOSTON -- October 17, 2011-- In a paper published today in Diabetologia, a team at Joslin Diabetes Center, headed by Mary R. Loeken, PhD, has identified the enzyme AMP kinase (AMPK) as key to the molecular mechanism that significantly increases the risk of neural tube defects such as spina bifida and some heart defects among babies born to women with diabetes.

Low birthweight infants have five times rate of autism

Autism researchers at the University of Pennsylvania School of Nursing have found a link between low birthweight and children diagnosed with autism, reporting premature infants are five times more likely to have autism than children born at normal weights.

Autism researchers at the University of Pennsylvania School of Nursing have found a link between low birthweight and children diagnosed with autism, reporting premature infants are five times more likely to have autism than children born at normal weight.

White children far more likely to receive CT scans than Hispanic, African-American children

White children are far more likely to receive cranial computed tomography (CT) scans in an emergency department following minor head trauma than are African-American or Hispanic children, a study by researchers at UC Davis has found.

The study findings do not indicate that CT scans are underused in treating African-American and Hispanic children, the researchers said. Rather, they suggest that white children may receive too many CT scans -- and for that reason may be exposed to unnecessary radiation.

Musical aptitude relates to reading ability

Auditory working memory and attention, for example the ability to hear and then remember instructions while completing a task, are a necessary part of musical ability. But musical ability is also related to verbal memory and literacy in childhood. New research published in BioMed Central's open access journal Behavioral and Brain Functions shows how auditory working memory and musical aptitude are intrinsically related to reading ability, and provides a biological basis for this link.

Promising new approach to treating debilitating nervous system disease

MAYWOOD, Il. -- A groundbreaking study in the journal Nature Medicine suggests what could become the first effective treatment for a debilitating and fatal disease of the central nervous system called SCA1.

The study, based on an animal model, found that the disease is linked to low levels of a multipurpose protein called VEGF. Researchers found that in mice that had SCA1, replenishing this protein lead to significant improvements in muscle coordination and balance.

Genetically responses to alcohol affect brain activation with and without alcohol

  • A low level of response (LR) to alcohol reflects at least in part a low brain response to alcohol and carries significant risk for the later development of alcoholism.
  • This study used functional magnetic resonance imaging (fMRI) to examine brain activation in individuals with low and high LRs to alcohol while they performed a cognitive task.
  • Significant differences detected in brain activation may contribute to the inability by individuals with a low LR to recognize modest levels of alcohol intoxication.
  • Psychopathic killers: Computerized text analysis uncovers the word patterns of a predator

    ITHACA, N.Y. – As words can be the soul's window, scientists are learning to peer through it: Computerized text analysis shows that psychopathic killers make identifiable word choices – beyond conscious control – when talking about their crimes.

    This research could lead to new tools for diagnosis and treatment, and have implications law enforcement and social media.
