Experienced meditators seem to be able switch off areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia, according to a new brain imaging study by Yale researchers.

Meditation’s ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. Brewer, assistant professor of psychiatry and lead author of the study published the week of Nov. 21 in the Proceedings of the National Academy of Sciences. Understanding how meditation works will aid investigation into a host of diseases, he said. (more…)

Yale School of Medicine researchers have discovered that a variant of a gene linked to heart disease also increases the risk of deadly aneurysms of blood vessels in the brain. The discovery of this link raises hopes for new treatments for intracranial aneurysms, which affect more than a half million people worldwide annually.

“Existing drugs already target this common pathway and, in the future, could help treat or prevent aneurysms in people who are at risk,” said Murat Gunel, professor of neurosurgery, genetics and neurobiology and senior author of the study, published the week of Nov. 21 in the Proceedings of the National Academy of Sciences.

*Research into aphasia – the inability to speak or write well-formulated sentences and words – is strong at the UA. Researchers have received $2 million toward the study of the condition.*

The National Institutes of Health have awarded the University of Arizona’s Aphasia Research Project in the department of speech, language and hearing sciences a $2 million grant to research communication impairments in adults who have suffered brain injury.

Aphasia – the inability to speak or write well-formulated sentences and words – is a common result of a stroke or a traumatic brain injury such as the one suffered by Rep. Gabrielle Giffords, who was shot in the head earlier this year. The bullet damaged regions of the brain that are critical for language and control of the right side of the body. (more…)

New Mouthwash Targeting Harmful Bacteria May Render Tooth Decay A Thing of The Past

A new mouthwash developed by a microbiologist at the UCLA School of Dentistry is highly successful in targeting the harmful Streptococcus mutans bacteria that is the principal cause tooth decay and cavities.

In a recent clinical study, 12 subjects who rinsed just one time with the experimental mouthwash experienced a nearly complete elimination of the S. mutans bacteria over the entire four-day testing period. The findings from the small-scale study are published in the current edition of the international dental journal Caries Research. (more…)
