The first study to investigate how dog brains process speech shows that our best friends in the animal kingdom care about both what we say and how we say it. Dogs, like people, use the left hemisphere to process words, a right hemisphere brain region to process intonation, and praising activates dog's reward center only when both words and intonation match, according to a study in Science.

Big data sets are full of dirty data, and these outliers, typos and missing values can produce distorted models that lead to wrong conclusions and bad decisions, be it in healthcare or finance. With so much at stake, data cleaning should be easier.

A research group under the leadership of Linköping University Professor Markus Heilig has identified an enzyme whose production is turned off in nerve cells of the frontal lobe when alcohol dependence develops. The deficiency in this enzyme leads to continued use of alcohol despite adverse consequences.
The discovery is now published in the number-one ranked psychiatric journal from the Nature Publishing Group, and could mean completely new possibilities for treating alcoholism.

Researchers at the University of California San Diego School of Medicine have identified 34 neural factors that predict adolescent alcohol consumption. The list, based upon complex algorithms analyzing data from neuropsychological testing and neuroimaging studies, was significantly more accurate --approximately 74 percent -- than demographic information alone.
The findings are published in the current issue of American Journal of Psychiatry.

It is now possible for machines to learn how natural or artificial systems work by simply observing them, without being told what to look for, according to researchers at the University of Sheffield.
This could mean advances in the world of technology with machines able to predict, among other things, human behaviour.

PORTLAND, Ore. - Researchers at Oregon State University and other institutions have discovered a type of drug delivery system that may offer new hope for patients with a rare, ultimately fatal genetic disorder - and make what might become a terrible choice a little easier.
No treatment currently exists for this disease, known as Niemann Pick Type C1 disease, or NPC1, that affects about one in every 120,000 children globally, and results in abnormal cholesterol accumulation, progressive neurodegeneration and eventual death.

CORVALLIS, Ore. - Researchers have discovered a mechanism of intercellular communication that helps explain how biological systems and actions - ranging from a beating heart to the ability to hit a home run - function properly most of the time, and in some scenarios quite remarkably.
The findings are an important basic advance in how cell sensory systems function, they shed light on the poorly-understood interaction between cells - and they also suggest that some of the damage done by cancer cells can be seen as a "failure to communicate."
