Derailed train of thought? Brain's stopping system may be at fault

Derailed train of thought? Brain's stopping system may be at fault

Have you had the experience of being just on the verge of saying something when the phone rang? Did you then forget what it is you were going to say? A study of the brain's electrical activity offers a new explanation of how that happens.

First diagnosed case of Alzheimer's disease in HIV-positive individual reported

WASHINGTON (April 15, 2016) -- Georgetown University researchers are reporting the first case of Alzheimer's disease diagnosed in an HIV-positive individual. The finding in a 71-year-old man triggers a realization about HIV survivors now reaching the age when Alzheimer's risk begins to escalate.

Immune cells help the brain to self-heal after a stroke

Immune cells help the brain to self-heal after a stroke

After a stroke, there is inflammation in the damaged part of the brain. Until now, the inflammation has been seen as a negative consequence that needs to be abolished as soon as possible. But, as it turns out, there are also some positive sides to the inflammation, and it can actually help the brain to self-repair.

"This is in total contrast to our previous beliefs", says Professor Zaal Kokaia from Lund University in Sweden.

New study examines the effect of ecstasy on the brain

Researchers from the University of Liverpool have conducted a study examining the effect ecstasy has on different parts of the brain.

Dr Carl Roberts and Dr Andrew Jones, from the University's Institute of Psychology, Health and Society, and Dr Cathy Montgomery from Liverpool John Moores University conducted an analysis of seven independent studies that used molecular imaging to examine the neuropsychological effect of ecstasy on people that use the drug regularly.

AACR: Results from clinical trial of personalized cellular therapy in brain tumors

PHILADELPHIA-- Immune cells engineered to seek out and attack a type of deadly brain cancer known as glioblastoma (GBM) were found to have an acceptable safety profile and successfully migrate to and infiltrate tumors, researchers from Penn Medicine and Harvard University reported at the AACR Annual Meeting 2016 (Abstract LB-083).

Smoking and schizophrenia: Understanding and breaking the cycle of addiction

Montreal, April 18, 2016 - Smoking addiction in schizophrenia can be explained by significantly increased activation of the ventro-medial prefrontal cortex (vmPFC), a region involved in the brain reward system. These new data, the result of a study by researchers at the Institut universitaire en santé mentale de Montréal (CIUSSS EST, Montreal) and the University of Montreal confirms the tendency to smoke and low smoking cessation rates of people with schizophrenia.

UC Davis study says logos make a group seem real

Organizations have logos, sports teams have mascots, countries have flags and national anthems. In marketing plans and political campaigns, a good logo is considered an essential tool for building brand identity.

New research at the University of California, Davis, shows that logos do far more -- creating the impression that a group is unified, effective and coordinated, even when the members of the group don't really seem that way on their own.

Too much 'noise' can affect brain development

Irvine, Calif., April 15, 2016 -- Using cutting-edge imaging technology, University of California, Irvine biologists have determined that uncontrolled fluctuations (known at "noise) in the concentration of the vitamin A derivative Retinoic acid (RA) can lead to disruptions in brain organization during development.

Identifying how a cell responds to a signal made by another cell, despite the level of noise present, may improve our understanding of developmental disorders.

A better nutritional facts panel

EAST LANSING, Mich. - The ubiquitous nutrition facts panel has graced food packages for many years. But can it be improved?

Results from a study led by Michigan State University and featured in a recent issue of the journal Food Policy indicates the answer is, "Yes."

Obesity is a serious and growing global health crisis. According to the World Health Organization, nearly 40 percent of the world's adults are overweight - a number that's doubled since 1980. While many factors contribute to this epidemic, improving food labeling could be one tool to fight it.

Fossil fuels could be phased out worldwide in a decade, says new study

The worldwide reliance on burning fossil fuels to create energy could be phased out in a decade, according to an article published by a major energy think tank in the UK.

Professor Benjamin Sovacool, Director of the Sussex Energy Group at the University of Sussex, believes that the next great energy revolution could take place in a fraction of the time of major changes in the past.
