Non-invasive Alzheimer's treatment restores memory using ultrasound

By - March 11, 2015 1 Picture
Alzheimer's disease is a chronic neurodegenerative disease that most often begins in people over 65 years of age. Usually it starts slowly and continues to worsen over time until the sufferer succumbs to an increasing loss of memory, bodily functions and, eventually, death. Research has shown that there is an association with Alzheimer's and the accumulation of plaques that affect the neuronal connections in the brain. Now researchers at the University of Queensland have discovered a new way to remove these toxic plaques using a non-invasive form of ultrasound therapy. Read More

Heart-on-a-chip beats a steady rhythm

By - March 11, 2015 1 Picture
The growing number of biological structures being grown on chips in various laboratories around the world is rapidly replicating the entire gamut of major human organs. Now one of the most important of all – a viable functioning heart – has been added to that list by researchers at the University of California at Berkeley (UC Berkeley) who have taken adult stem cells and grown a lattice of pulsing human heart tissue on a silicon device.

Prosthetic arm takes alternate route to mind control

By - March 9, 2015 3 Pictures
Researchers from the Medical University of Vienna have developed a technique that allows amputees to control a robotic prosthesis with their mind when there's no neural connection left to exploit between the brain and the part of the hand that remains. Called "bionic reconstruction," the procedure was applied to three patients who were able to successfully use the prosthesis to undertake routine activities, thereby improving their quality of life.

Drug-delivering nano "drones" to help prevent heart attacks

By - March 2, 2015 2 Pictures
Scientists have developed targeted, biodegradable nano "drones" to deliver anti-inflammatory drugs that heal and stabilize arterial plaque in mice. Their work could pave the way for more effective prevention of heart attack and stroke in humans caused by atherosclerosis, in which artery walls thicken and suffer reduced plasticity due to an accumulation of white blood cells.

Muscle injection could help burn more calories during routine activities

By - February 27, 2015 1 Picture
The future of weight loss could look like this. Inject your muscles with a compound that helps them burn more calories than usual and then do your daily chores to shed those extra pounds. That's the vision of a team of scientists who are working on a muscle-targeted injection therapy to help overweight people lose weight easily, even with low to moderate exercise. Read More
