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

Ultrasound technique shown to reverse Alzheimer’s symptoms in mice

By - February 12, 2015 2 Pictures
Magnetic resonance (MR) imaging-guided ultrasound, a technology that involves highly-targeted ultrasound beams and monitoring their effects through imaging, has shown to help treat symptoms of Alzheimer’s disease in mice. The treatment was found to improve brain performance in the animals and has the researchers hopeful that the technique may prove effective in improving cognitive behavior in humans. Read More

New acoustic levitation device goes out of alignment to expand potential applications

By - January 6, 2015 3 Pictures
Acoustic levitators are already pretty intriguing devices, in that they use opposing sound waves to suspend small objects in mid-air. Now, however, scientists from Brazil's University of São Paulo have created what they claim is a better acoustic levitator. It's less fussy about the exact orientation of its components, making it more feasible for use in practical applications. Read More

New ultrasound research creates holographic objects that can be seen and felt

By - December 2, 2014 1 Picture
Haptic feedback has become a common feature of recent technology, but such systems usually rely on stimulation of parts of the user’s body via direct mechanical or acoustic vibration. A new technique being developed by researchers at the University of Bristol promises to change all of this by using projected ultrasound to directly create floating, 3D shapes that can be seen and felt in mid-air.

Water pipe-inspection robot designed to have a light touch

By - December 2, 2014 1 Picture
When it comes to robots that perform internal inspections of water pipes, virtually all of them move along on rubber tires or treads. As that rubber grips against the inside of the pipe, however, it dislodges rust particles that ultimately end up coming out of peoples' taps. In an effort to address that problem, the European Union TRACT project is developing a propeller-driven inspection robot that keeps the pipe-touching to a minimum. Read More

Metamaterials allow ultrasound to penetrate bone and metal

By - November 23, 2014 1 Picture
Score another point for metamaterials. Researchers at North Carolina State University have designed complementary metamaterials that will aid medical professionals and engineers in diagnosing problems under the skin. These metamaterials are structured to account for so-called "aberrating layers" that block or distort the acoustic waves used in ultrasounds, making it possible to now conduct ultrasounds of a person's head or an airplane's wing – among other things.

HaptoMime lets users "touch" a mid-air display

By - October 29, 2014 2 Pictures
Touchscreen interfaces may make our lives easier, but the things do tend to get smeared with finger oil and whatnot, plus they're notorious for spreading germs. That's why a team of researchers at the University of Tokyo, led by assistant professor Yasuaki Monnai, have developed the HaptoMime. It's an ATM-like interface that lets the user feel like they're touching a glass screen, when in fact they're touching nothing at all. Read More
