A research team led by an award-winning genomicist at Western University has developed a new method for identifying mutations and prioritizing variants in breast and ovarian cancer genes, which will not only reduce the number of possible variants for doctors to investigate, but also increase the number of patients that are properly diagnosed.

These potentially game-changing technologies, developed by Peter Rogan, PhD, students and his collaborators from Western's Schulich School of Medicine & Dentistry, reveal gene variants that were missed by conventional genetic testing.

Most people are aware of open-source computer programs. These free programs, accessible by anyone, spread technology to distant corners of the world. Cutting-edge innovations, however, come at a price. As a result, many software companies license their work.

These same concerns exist within the seed-development arena. Some plant researchers support the free exchange of new varieties of seeds and plants. Doing so, they argue, benefits both plant breeders and farmers. Considering seeds "intellectual property" may seem harmful to this free exchange of information.

New research published today in the journal Scientific Reports has revealed for the first time that half of the world's farmed fish have hearing loss due to a deformity of the earbone.

Like humans, fish have ears which are essential for hearing and balance, so the findings are significant for the welfare of farmed fish as well as the survival of captive-bred fish released into the wild for conservation purposes.

The University of Melbourne-led study found that half of the world's most farmed marine fish, Atlantic salmon, have a deformity of the otolith or 'fish earbone', much like the inner ear of mammals. The deformity was found to be very uncommon in wild fish.

SAN ANTONIO (April 27, 2016) -- It's an unsettling thought: You could be walking around for 20 years developing Parkinson's disease and not even know it.

And once symptoms appear, it's too late for a cure.

What if a therapy that treats the root causes of Parkinson's, not just the symptoms, could be started earlier?

• Scientists identify hundreds of infected cells at different points of initial entry

What if a map of the brain could help us decode people's inner thoughts?

Scientists at the University of California, Berkeley, have taken a step in that direction by building a "semantic atlas" that shows in vivid colors and multiple dimensions how the human brain organizes language. The atlas identifies brain areas that respond to words that have similar meanings.

The findings, to be published April 28, 2016 in the journal Nature, are based on a brain imaging study that recorded neural activity while study volunteers listened to stories from the "Moth Radio Hour." They show that at least one-third of the brain's cerebral cortex, including areas dedicated to high-level cognition, is involved in language processing.
