Ultrasound

What exactly does sleep do to the brain, and how could its benefits be boosted? To investigate, the US Army has awarded researchers a grant to develop a portable skullcap that can monitor and adjust the flow of fluid through the brain during sleep.

Although scientists have been working on "microbots" that could deliver drugs within the body, one challenge remains – powering the things without the use of bulky onboard batteries. A new approach utilizes ultrasound waves that act on tiny bubbles.

Cardiovascular diseases are the leading cause of death worldwide, but numbers could be reduced with better early warning systems. A new study has outlined just such a system, using nanoparticles that make atherosclerotic plaques emit ultrasound waves.

CAR T cell immunotherapy is a promising treatment for cancer, but it can trigger dangerous side effects. A new study precisely targets cancer by engineering CAR T cells to activate at higher temperatures, then heating tumors with 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.
