Song-learning neurons identified in songbirds
A group of neurons called the corticobasal ganglia projecting neurons are important for vocal learning in young birds, but not in adult birds, according to a new study.

Training parents is key to helping children eat a variety of foods
Families dealing with the stress and frustration of their child's overly picky eating habits may have a new addition to their parental toolbox. Pediatric researchers recently described a brief group cognitive-behavioral therapy program that provides parents with specific techniques to improve their child's mealtime behaviors and expand the range of foods their children will eat. Although the study size was small, the parents involved reported 'life-changing' improvements.

A research team has created a third approach to engineering proteins that uses deep learning to distill the fundamental features of proteins directly from their amino acid sequence without the need for additional information.

Three-hundred researchers have identified 48 common genetic variants that are associated with the size of the brainstem and other subcortical structures deep within the brain. This is the first step toward understanding how to devise treatments for disorders affecting these structures.

Researchers are giving us double the reasons to pay attention to our cardiovascular health – showing in a recent study that good heart health can equal good brain health.
Read moreResistance to last resort drug arose in patient over 3 weeks
French investigators have described development of resistance to one of the last resort therapies used to treat extremely drug-resistant Pseudomonas aeruginosa. That resistance arose in a single patient over a scant 22 days. They subsequently identified the single nucleotide mutation in P. aeruginosa that caused the resistance.
