Prescription for double-dose algebra proves effective

Martin Gartzman sat in his dentist's waiting room last fall when he read a study in Education Next that nearly brought him to tears.

A decade ago, in his former position as chief math and science officer for Chicago Public Schools, Gartzman spearheaded an attempt to decrease ninth-grade algebra failure rates, an issue he calls "an incredibly vexing problem." His idea was to provide extra time for struggling students by having them take two consecutive periods of algebra.

Low-cost 'cooling cure' would avert brain damage in oxygen-starved babies

When babies are deprived of oxygen before birth, brain damage and disorders such as cerebral palsy can occur. Extended cooling can prevent brain injuries, but this treatment is not always available in developing nations where advanced medical care is scarce. To address this need, Johns Hopkins undergraduates have devised a low-tech $40 unit to provide protective cooling in the absence of modern hospital equipment that can cost $12,000.

'Evolutionary glitch' possible cause of childhood ear infections

Researchers at King's College London have uncovered how the human ear is formed, giving clues as to why children are susceptible to infections such as glue ear. The work was funded by the UK Medical Research Council and published today in the journal Science.

Multiple sclerosis research: The thalamus moves into the spotlight

BUFFALO, N.Y. – A growing body of research by multiple sclerosis (MS) investigators at the University at Buffalo and international partners is providing powerful new evidence that the brain's gray matter reflects important changes in the disease that could allow clinicians to diagnose earlier and to better monitor and predict how the disease will progress.

Reward linked to image is enough to activate brain's visual cortex

Once rhesus monkeys learn to associate a picture with a reward, the reward by itself becomes enough to alter the activity in the monkeys' visual cortex. This finding was made by neurophysiologists Wim Vanduffel and John Arsenault (KU Leuven and Harvard Medical School) and American colleagues using functional brain scans and was published recently in the leading journal Neuron.

Do disruptions in brain communication have a role in autism?

New Rochelle, NY, March 21, 2013—A new study of patterns of brain communication in toddlers with autism shows evidence of aberrant neural communication even at this relatively early stage of brain development. The results are presented in an article in Brain Connectivity, a bimonthly peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Brain Connectivity website at http://www.liebertpub.com/brain.

Misregulated genes may have big autism role

PROVIDENCE, R.I. [Brown University] — A new study finds that two genes individually associated with rare autism-related disorders are also jointly linked to more general forms of autism. The finding suggests a new genetic pathway to investigate in general autism research.

Tackling issues of sexuality among people with dementia

Managing the delicate issue of sexual expression amongst people with dementia is the focus of a new education resource produced by Griffith University researcher Dr Cindy Jones.

The first resource of its kind and the subject of funding from the Department of Health and Aging and Queensland Dementia Training and Study Centres (DTSC),Sexualities and Dementia: Education Resource for Health Professionals is aimed at assisting health professionals working across care settings.

Dysfunction in cerebellar Calcium channel causes motor disorders and epilepsy

A dysfunction of a certain Calcium channel, the so called P/Q-type channel, in neurons of the cerebellum is sufficient to cause different motor diseases as well as a special type of epilepsy. This is reported by the research team of Dr. Melanie Mark and Prof. Dr. Stefan Herlitze from the Ruhr-Universität Bochum. They investigated mice that lacked the ion channel of the P/Q-type in the modulatory input neurons of the cerebellum.

The neuroscience of finding your lost keys

LA JOLLA, CA----Ever find yourself racking your brain on a Monday morning to remember where you put your car keys?

When you do find those keys, you can thank the hippocampus, a brain region responsible for storing and retrieving memories of different environments-such as that room where your keys were hiding in an unusual spot.

Exploring the link between traumatic brain injury and people who are homeless

TORONTO, March 21, 2013—Homeless people and their health care providers need to know more about traumatic brain injuries to help prevent and treat such injuries, a new study has found.

Homeless people have a disproportionately higher risk for TBI compared to the general population, yet little is known about the severity of those injuries, who exactly is suffering from them and what the long-term consequences are.

Researchers link Gulf War Illness to physical changes in brain fibers that process pain

WASHINGTON — Researchers at Georgetown University Medical Center (GUMC) have found what they say is evidence that veterans who suffer from "Gulf War Illness" have physical changes in their brains not seen in unaffected individuals. Brain scans of 31 veterans with the illness, compared to 20 control subjects, revealed anomalies in the bundles of nerve fibers that connect brain areas involved in the processing and perception of pain and fatigue.

Older grandfathers pass on autism risk through generations

Men who have children at older ages are more likely to have grandchildren with autism compared to younger grandfathers, according to new research. This is the first time that research has shown that risk factors for autism may accumulate over generations.

The study led by King's College London's Institute of Psychiatry, Karolinska Institutet in Sweden and the Queensland Brain Institute in Australia is published today in JAMA Psychiatry.

Brain mapping reveals neurological basis of decision-making in rats

Scientists at UC San Francisco have discovered how memory recall is linked to decision-making in rats, showing that measurable activity in one part of the brain occurs when rats in a maze are playing out memories that help them decide which way to turn. The more they play out these memories, the more likely they are to find their way correctly to the end of the maze.

Media coverage of mass shootings contributes to negative attitudes towards mental illness

News stories about mass shootings involving a shooter with mental illness heighten readers' negative attitudes toward persons with serious mental illness, according to a new report by the Johns Hopkins Bloomberg School of Public Health. The researchers also examined how such news stories impact support for policies to reduce gun violence.
