Music training, begun as late as high school, may help improve the teenage brain's responses to sound and sharpen hearing and language skills, suggests a new study. The research indicates that music instruction helps enhance skills that are critical for academic success. 

The gains were seen during group music classes included in the schools' curriculum, suggesting in-school training accelerates neurodevelopment.

In a new study, women considered the position and shape of the urethral opening to be the least important aspects of a penis' appearance.

They also perceived the genitals of men who underwent surgery to treat distal hypospadias--a congenital condition in which the opening of the urethra is on the underside of the penis--to be as normal-looking as nonaffected, circumcised genitals.

"The information may help prevent the development of shame or impaired genital perceptions about penile appearance," said Dr. Norma Ruppen, lead author of the study.

The downside to computer programs is they lack the ability to interpret. A tiny human can look at a picture of a chicken and a cartoon of a chicken and know that's a chicken while a computer program cannot.

Researchers from Queen Mary University of London believe they have overcome one obstacle and have built the first computer program that can recognize hand-drawn sketches better than humans. They call it Sketch-a-Net and in their tests it is capable of correctly identifying the subject of sketches 74.9 percent of the time compared to humans that only managed a success rate of 73.1 percent.

The human organism contains hundreds of distinct cell types that often differ from their neighbors in shape and function. To acquire and maintain its characteristic features, each cell type must express a unique subset of genes. Neurons, the functional units of our brain, develop through differentiation of neuronal precursors, a process that depends on coordinated activation of hundreds and possibly thousands of neuron-specific genes.

It may seem like infants just sleep, eat and cry, but newborn brains are full of activity and they are already gathering and processing important information from the world around them. At just two days after birth, babies are already able to process language using processes similar to those of adults.

Researchers have demonstrated that they are sensitive to the most important parts of words, the edges, a cognitive mechanism which has been repeatedly observed in older children and adults.

Centralized ventilation systems that exchange heat between the air inside and outside a building often come with a lot of pipes and shafts while compact, decentralized ventilation systems distributed throughout a building can provide a real added-value both in terms of design, comfort and energy efficiency.

The Green Ventilation system promise to balance inbound and outbound air flow in such a way that it reduces heating and cooling requirements—a principle called balanced heat recovery. The advantage of this system is that it can be added to building envelope components such as windows, walls, insulation materials, terminal heating and cooling units and lintels.
