Medicine & Health news

Some neurons can multitask, raising questions about the importance of specialization

Think about all the things you are doing at this moment. As your eyes scan across the lines of this article, maybe your brain is processing the smell of coffee brewing down the hall and the sound of leaf blowers outside your window. Maybe you are tapping your foot and spinning a pen between your fingers. At any given moment, your brain is simultaneously processing a multitude of information from your senses while supporting a dizzying array of behaviors.

A new study shows for the first time that playing action video games improves not just the skills taught in the game, but learning capabilities more generally.

Sad music hits positive notes of emotional rewards

(Medical Xpress)—Sadness is discouraged; it's a mood to flee. We tell children not to look so sad. We tell adults to wipe that sad look off their face and smile. We worry that prolonged sadness needs medical attention. So why do people deliberately spend their money to hear sad songs—and flock to big-ticket concerts, applauding the loudest for the saddest tunes imaginable? If sadness is such a negative, why do we send our money and time wallowing in sad tunes?

New mechanism for febrile seizures in young children discovered

Febrile seizures are among the most dreaded complications of infectious diseases in small children. An international research team composed of experts from the Universities of Tübingen, Leuven and Luxembourg has now made a breakthrough by demonstrating the existence of a previously unknown cause for this most frequent form of epileptic attacks in small children. As a study just published in the medical journal Nature Genetics shows, mutations in the STX1B gene are responsible for the children's pathological reactions to fever. The gene mutations lead to an impaired regulation in the release of certain nerve cell messenger substances. The consequence of this is an increase of involuntary electrical discharges in the brain, accompanied by epileptic febrile seizures. In the long run, the newly discovered gene alterations can also be the source of serious epilepsy and mental disability. The scientists now hope to develop new forms of! therapy on the basis of their discoveries.

Molecular breakthrough could halt the spread of prostate cancer

Scientists believe a new treatment, shown to be effective in mice, could halt the growth of tumours in patients with prostate cancer.

Study suggests a unified model for how DNA is read, offering insight into how genes evolve

There are roughly 20,000 genes and thousands of other regulatory "elements" stored within the three billion letters of the human genome. Genes encode information that is used to create proteins, while other genomic elements help regulate the activation of genes, among other tasks. Somehow all of this coded information within our DNA needs to be read by complex molecular machinery and transcribed into messages that can be used by our cells.

Dip in emergency hospital admissions via GPs while figures soar for A&E

The number of emergency admissions to hospital via A&E departments increased markedly in England from 2001/02 to 2010/11, while the number via GPs decreased, according to analysis published today in the Journal of the Royal Society of Medicine. Researchers at Imperial College London, funded by the National Institute for Health Research (NIHR), estimated that the annual number of emergency hospital admissions via A&E departments rose by 72% (2.1 million to 3.6 million) between 2001/2 and 2010/11. In the same period there was a 17% decrease in emergency hospital admissions via GPs (1.12 million to 0.93 million). These diverging trends could reflect changing roles for A&E departments and GP practices in providing urgent and emergency care in the NHS.
