Aerobic exercise can increase brain size and improve cognition in children, older adults

Exercise doesn't only strengthen your heart and muscles - it also beefs up your brain. Dozens of studies now show that aerobic exercise can increase the size of critical brain structures and improve cognition in children and older adults.

Study paves way for new prosthetics that connect directly to the nervous system

For an amputee, replacing a missing limb with a functional prosthetic can alleviate physical or emotional distress and mean a return of vocational ability or cosmetics. Studies show, however, that up to 50 percent of hand amputees still do not use their prosthesis regularly due to less than ideal functionality, appearance, and controllability. But Silvestro Micera, of the -cole Polytechnique F-d-rale de Lausanne (EPFL) in Switzerland, is paving the way for new, smart prosthetics that connect directly to the nervous system.

Research reveals how quickly the Achilles tendon can regenerate

The Achilles heel of the body - getting over damage to tendons can be a long and painful process. By combining the nuclear tests of the 1950s with tissue samples and modern technology, a research collaboration between the Aarhus University and University of Copenhagen now reveals why the healing process is so slow.

Oxidized CaMKII may increase risk of death in diabetics following heart attack

Having diabetes doubles a person's risk of dying after a heart attack, but the reason for the increased risk is not clear. A new University of Iowa study suggests the link may lie in the over-activation of an important heart enzyme, which leads to death of pacemaker cells in the heart, abnormal heart rhythm, and increased risk of sudden death in diabetic mice following a heart attack.

Dietary impacts, health changes and oral pathogen genomic evolution

DNA preserved in calcified bacteria on the teeth of ancient human skeletons has shed light on the health consequences of the evolving diet and behaviour from the Stone Age to the modern day.

Brain damage can persist for decades after original head trauma

As the National Football League braces for lawsuits by 4000 former players alleging the league failed to protect them from the long-term consequences of concussions, game-changing research by a leading Canadian researcher shows damage to the brain can persist for decades after the original head trauma.

Infrared signaling could create sense of touch in artificial limbs

Rats can't usually see infrared light, but they have "touched" it in a Duke University lab. The rats sensed the light as a sensation of touch after Duke neurobiologist Miguel Nicolelis and his team fitted the animals with an infrared detector wired to electrodes implanted in the part of the mammalian brain that processes information related to the sense of touch.

Study shows how gene mutations affect calcium pathway in arrhythmia

Using powerful X-rays, University of British Columbia researchers have reconstructed a crime scene too small for any microscope to observe - and caught the culprit of arrhythmia in action.

Brain health just as important as physical health

We all know the importance of keeping healthy and are familiar with the refrains of 'exercise more', 'eat better' and 'get regular physicals'. But what about our mental health? Professor Barbara Sahakian, best known for her expertise on cognitive enhancers, challenges society (and government) to prioritise mental health in the same way as we do physical health.

Two studies discover new enzyme that acts as a sensor of innate immunity

Two studies by researchers at UT Southwestern Medical Center could lead to new treatments for lupus and other autoimmune diseases and strengthen current therapies for viral, bacterial, and parasitic infections.

Colorectal cancer outcomes could be improved with regular genetic screening for Lynch syndrome

Cleveland Clinic researchers have found that colorectal cancer outcomes could be improved with regular genetic screening for Lynch syndrome, the most common hereditary, adult-onset cause of colorectal cancer, as published in the online version of the Journal of Clinical Oncology.

'Vaccine patch' could make immunizations cheaper, easier

"An innovative new way to deliver vaccines could drastically improve the health of the third world, and even the first world, by making vaccines cheaper and easier to distribute and use," Business Insider reports, adding, "The 'vaccine patch' would be as easy to apply as a Band-Aid, and would be stable for weeks at room temperature."

Gut microbes can affect severity of kidney disease brought on by melamine poisoning

Microbes present in the gut can affect the severity of kidney disease brought on by melamine poisoning, according to an international study led by Professor Wei Jia at the University of North Carolina in collaboration with the research group of Professor Jeremy Nicholson at Imperial College London.

Parkinson's-related mutations may also affect vision

The most common genetic cause of Parkinson's is not only responsible for the condition's distinctive movement problems but may also affect vision, according to new research by scientists at the University of York.

Researchers identify mechanism through which mitochondria control breast tumor aggressiveness

Doctors currently struggle to determine whether a breast tumor is likely to shift into an aggressive, life-threatening mode-an issue with profound implications for treatment. Now a group from The Scripps Research Institute (TSRI) has identified a mechanism through which mitochondria, the powerhouses of a cell, control tumor aggressiveness.

TSG might be novel compound for treatment of Alzheimer's and dementia with Lewy body

Administration of the active compound tetrahydroxystilbene glucoside (TSG) derived from the Chinese herbal medicine Polygonum multiflorum Thunb, reversed both overexpression of α-synuclein, a small protein found in the brain, and its accumulation using a mouse model of Alzheimer's disease.

Study finds little long-term survival advantage for women with ovarian cancer and BRCA mutations

Researchers at Moffitt Cancer Center and colleagues in Toronto and at Yale University studied the long-term survival of women with a BRCA1 or BRCA2 gene mutation who were diagnosed with invasive ovarian cancer. They found that the short-term benefit to having either mutation does not lead to a long-term survival benefit.
