Researchers at the University of Adelaide say they may have discovered a new target in the fight against depression: a faulty gene that is linked to cardiovascular and metabolic conditions.

A heathy diet is linked to better reading skills in the first three school years, shows a recent study from Finland. Published in the European Journal of Nutrition, the study constitutes part of the Physical Activity and Nutrition in Children Study conducted at the University of Eastern Finland and the First Steps Study conducted at the University of Jyväskylä.

It does not take an infinite number of monkeys to type a passage of Shakespeare. Instead, it takes a single monkey equipped with brain-sensing technology - and a cheat sheet.

That technology, developed by Stanford Bio-X scientists Krishna Shenoy, a professor of electrical engineering at Stanford, and postdoctoral fellow Paul Nuyujukian, directly reads brain signals to drive a cursor moving over a keyboard. In an experiment conducted with monkeys, the animals were able to transcribe passages from the New York Times and Hamlet at a rate of up to 12 words per minute.

Glioblastomas exert an influence on the microglia, immune cells of the brain, which causes them to stimulate cancer growth rather than attacking it. In a study published in the journal Nature Immunology, an international research team led from Sweden's Karolinska Institutet now explains the molecular mechanisms behind this action.

Boston, Mass. -- Researchers from Massachusetts Eye and Ear have, for the first time, linked symptoms of difficulty understanding speech in noisy environments with evidence of cochlear synaptopathy, a condition known as "hidden hearing loss," in college-age human subjects with normal hearing sensitivity.

For the first time, abnormal brain development following a Zika infection during pregnancy has been documented experimentally in the offspring of a non-human primate.

The researchers' observations of how Zika virus arrested fetal brain formation in a pigtail macaque could provide a model for testing therapeutic interventions.

The findings are reported Sept. 12 in the advanced online publication of Nature Medicine.

LA JOLLA--Our brains contain a surprising diversity of DNA. Even though we are taught that every cell in our body has the same DNA, in fact most cells in the brain have changes to their DNA that make each neuron a little different.

Professor Byung-Chang Suh's research team from the Department of Brain and Cognitive Sciences succeeded in identifying a new operational mechanism principle of the 'Acid-sensing Ion Channel,' which recognizes internal pain in an organism.

The findings are expected to have a significant impact on further studies focusing on the development of therapeutic agents that control pain by providing a more precise understanding of the operational mechanism of the 'Acid-sensing Ion Channel' that plays a pivotal role in transmitting pain signals.

Suicide is the result of a complex interaction among a whole host of factors among which "it is worth highlighting clinical factors such as a history of psychiatric and psychosocial disorders, the loss of the social support network, the loss of employment or acute stress", pointed out Jon García-Ormaza, lecturer in psychiatry at the UPV/EHU and medical psychiatrist at University Hospital Cruces.

Researchers have clarified important mechanisms involved in the formation of neural circuits in the brain. This group also discovered that delta-9-tetrahydrocannabinol (THC), a psychoactive substance also found in cannabis, causes disruption of neural circuits within the cortex. These results explain why cannabis may be harmful and have potential to find application in the functional recovery of brain injury and in cases of dementia.
