We may think that not wanting to live around relatives is a modern trait, but our closest anthropological relatives, modern day hunter-gatherers, choose to not live among family members as much as we think. That goes for when males and females have the choice.

Researchers have discovered that a brain protein plays a key role in controlling binge drinking, defined as drinking to the point of intoxication. They found that deleting the gene for this protein in mice ramped up alcohol consumption and prevented the brain from signaling the rewarding properties of alcohol. 

The goal of the new study was to identify the role of a member of the "G protein-gated inwardly rectifying potassium channel" (GIRK) family in the behavioral and cellular responses to alcohol.

Sometimes one food fallacy can conflict with another, and so you must choose - if you like paying over 240 percent more for a gluten-free label and 200 percent more for a probiotics label, you may have to pick between them. 

Your genes may influence how sensitive you are to emotional information, according to a new study which found that carriers of a certain genetic variation perceived positive and negative images more vividly, and had heightened activity in certain brain regions.

California Senator Dianne Feinstein recently declared war on homemade soap in order to placate her corporate donors, so it is no surprise the public holds her in rather poor regard. Yet it is not just her, U.S. Congress approval ratings are at record lows across the board and a new study speculates that this may be partly due to a decline in the use of warm, agreeable language in the House.

The analysis found that the use of prosocial words -- language such as cooperate or contribute -- by lawmakers predicts public approval of Congress six months later.

A study of portable ultrasound in detecting the presence of minor fractures in patients showed that 85% of patients with a fracture confirmed by X-ray had injuries detected through ultrasonography.

You'd still want a radiographer to rule out fractures but emergency clinicians could rule in fractures using ultrasound images, they conclude.

Ultrasound is a high pitched sound wave generated at a frequency of more than 20,000Hz in air, though the frequency changes depending on the density of the objects through which it passes.
