Ultrasound

It goes without saying that the earlier someone can be warned of an impending heart attack or stroke, the better. A new skin patch could provide such warnings, by sending ultrasound pulses into the wearer's body.

While electric vehicles are greener than their fuel-burning counterparts, their battery packs still aren't as recyclable as they could be. A new process could help, by more efficiently extracting reusable materials from old lithium-ion batteries.

Scientists have uncovered some surprising news ways ultrasound can improve cognition in mouse models of Alzheimer's disease, something they believe could have wider implications for restoring cognition in the elderly.

Results from a trial testing an ultrasound therapy for hypertension show the treatment can deliver meaningful reductions in blood pressure. The treatment is based on a hypothesis that disrupting signals from renal nerves can reduce blood pressure.

Engineers at Columbia University have developed the smallest single-chip system ever created, which can be implanted with a hypodermic needle to measure temperature inside the body, and possibly much more.

Manufactured by Austrian startup Tec-Innovation, the InnoMake shoe uses ultrasound sensors to warn blind users of obstacles in their path. The footwear may soon become even more capable, though, thanks to integrated cameras.

When we think of camouflage, it’s usually a visual pattern. But how do you hide from a predator that uses sound to find food, like a bat? If you’re a firefly, it turns out you might resort to a cacophony of ultrasound that acts like “musical armor.”

A landmark proof-of-concept study reveals a novel brain-machine interface using ultrasound tracking brain activity to predict subsequent motor movements. The preliminary research suggests a non-invasive way of controlling computers with one's mind.

Obesity is one of the most pressing health problems, but a new study suggests a potential non-invasive treatment. In tests in mice, researchers found that directing ultrasound to the liver helped reduce a number of markers associated with obesity.

The 2019 North American outbreak of E. coli contamination in romaine lettuce doubtless got many people thinking about how to most effectively wash their leafy veggies. Well, a new study suggests that using ultrasonic water may be the best way to go.

A new study has demonstrated how the brain's waste disposal system might be kicked into gear via ultrasound to treat Alzheimer's, with the technique proving effective in stimulating activity of this system in patients as part of early human trials.

Although various groups are working on nanoparticles that could be used for directed drug delivery via the bloodstream, most of those particles are made to "go with the flow." Now, however, researchers have created ones that can travel upstream.
