Exercise during pregnancy gives newborn brain development a head start
As little as 20 minutes of moderate exercise three times per week during pregnancy enhances the newborn child's brain development, according to researchers at the University of Montreal and its affiliated CHU Sainte-Justine children's hospital.

'1-stop' radiotherapy could offer an alternative to lengthy and inconvenient post-surgery procedures for breast cancer
Two new studies, published in The Lancet and The Lancet Oncology, show that targeted radiotherapy delivered during surgery could offer a viable alternative to current procedures -- which require women to attend daily radiotherapy sessions for weeks after surgery -- for some women undergoing surgery for early breast cancer.

Cause of genetic disorder found in 'dark matter' of DNA
Pancreatic agenesis results in babies being born without a pancreas, leaving them with a lifetime of diabetes and problems digesting food.

The contribution of coding variants to psoriasis much smaller than thought
Coding variants in immune disease-related genes play only a small part in the overall genetic risk for psoriasis, according to a new study led by Anhui Medical University and BGI.

New evidence on the biological basis of highly impulsive and aggressive behaviors
Physical and chemical changes in the brain during development can potentially play a role in some delinquent and deviant behaviors, according to research released today.

'Saving our fish' needs more than a ban on discarding
Banning the practice of throwing unmarketable or over-quota fish back into the sea is just one of the measures needed to deliver sustainable fisheries according to new research from the University of East Anglia.

Hormones impact stress, memories, and understanding social cues
Research released today demonstrates unexpected roles that sex hormones may play in the cognitive function of females, including memory and interpreting social cues.

How zinc starves lethal bacteria to stop infection
Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.

All aboard the nanotrain network
Tiny self-assembling transport networks, powered by nano-scale motors and controlled by DNA, have been developed by scientists at Oxford University and Warwick University.

Research reveals new understanding, warning signs, and potential treatments for multiple sclerosis
Scientists are gaining a new level of understanding of multiple sclerosis that may lead to new treatments and approaches to controlling the chronic disease, according to new research released today at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

How sleep aids visual task learning
At the Society for Neuroscience annual meeting in San Diego Nov.

World's largest disease database will use artificial intelligence to find new cancer treatments
A new cancer database containing 1.7 billion experimental results will utilise artificial intelligence similar to the technology used to predict the weather to discover the cancer treatments of the future.

Molecular interplay explains many immunodeficiencies
Australian scientists have described an exquisitely balanced interplay of four molecules that trigger and govern antibody production in immune cells.

Research by Saint Louis University scientists offers way to disrupt fibrosis
Scientists have identified a pathway that regulates fibrosis, suggesting a possible pharmacologic approach to treat patients with a broad range of fibrotic diseases.

Scientists discover radioactive tracer that could be used to predict patients' risk of heart attack
New research, published in The Lancet, reveals that a radioactive tracer called 18F-sodium fluoride -- which has been used in bone imaging for several decades -- can accurately identify and localise high-risk blockages in the heart (called coronary plaques) which can lead to heart attacks and other serious coronary events.

Hope for transplant patients as study finds key to organ scarring
Patients with damaged organs could be helped by new treatments after scientists have discovered how tissues scar.

Fast-mutating DNA sequences shape early development; guided evolution of uniquely human traits
What does it mean to be human? According to scientists the key lies, ultimately, in the billions of lines of genetic code that comprise the human genome.

AAPS announces 2013 Fellows
The American Association of Pharmaceutical Scientists is pleased to announce its 2013 AAPS Fellows.

The Hebrew University of Jerusalem is one of 11 universities, medical centers and research institutes in seven countries participating in ncRNAPain, a new European research project that aims at further exploring the biological mechanisms underlying chronic pain.

Single-cell genome sequencing gets better
Researchers led by bioengineers at the University of California, San Diego have generated the most complete genome sequences from single E. coli cells and individual neurons from the human brain.
