Aortic stenosis is a progressive and potentially fatal condition, affecting about five per cent of 65-year-olds in the US -- with increasing prevalence in advancing age. Symptoms include chest pains, a rapid fluttering heartbeat and feeling dizzy, short of breath and fatigued -- particularly with activity. The new study reveals how a four-dimensional flow (4D flow) MRI scan can diagnose aortic stenosis more reliably than current ultrasound techniques.

It's satisfying to finally see the rolling boil, behind which complex physical mechanisms are at play. When this happens, the bubbles that form continuously change in shape and size. These dynamic movements influence the surrounding fluid flow, thereby affecting the efficiency of heat transfer from the heat source to the water. Manipulating small amounts of liquid at high speeds and frequencies is essential for processing large numbers of samples in medical and chemical fields, such as in cell sorting. Microbubble vibrations can create flows and sound waves, aiding in liquid manipulation. However, the collective behavior and interactions of multiple bubbles is poorly understood, so their applications have been limited.

When this happens, not only do your brain and ears perceive it, but your cells may also. Technically speaking, sound is a simple phenomenon, consisting of compressional mechanical waves transmitted through substances, which exists universally in the non-equilibrated material world. Sound is also a vital source of environmental information for living beings, while its capacity to induce physiological responses at the cell level is only just beginning to be understood.

Research has demonstrated that digital voice measures can detect early signs of cognitive decline by analyzing features such as speech rate, articulation, pitch variation and pauses, which may signal cognitive impairment when deviating from normative patterns. However, voice data introduces privacy challenges due to the personally identifiable information embedded in recordings, such as gender, accent and emotional state, as well as more subtle speech characteristics that can uniquely identify individuals. These risks are amplified when voice data is processed by automated systems, raising concerns about re-identification and potential misuse of data.

They targeted freshly isolated human immune cells with tightly focused ultrasound beams and clinically approved contrast agent microbubbles. When hit with the ultrasound, the bubbles vibrate at extremely high frequency, acting as a push-pull on the walls of the T cell's membranes. This can mimic the T cell's natural response to the presence of an antigen. The T cell then begins to secrete vital signalling molecules that would otherwise be restricted by the tumor's hostile microenvironment. The process does not damage the cell itself.

New research could help solve the problem.

Attachable to the skin with an adhesive and powered by a small battery, the device wirelessly captures high-resolution images of muscle movements, enabling continuous, long-term monitoring. When worn on the rib cage, it effectively monitored diaphragm function for respiratory health assessments. When worn on the forearm, it accurately captured hand gestures, allowing users to control a robotic arm and even navigate virtual games. This new technology has potential applications in healthcare for conditions affecting muscle function, as well as in human-machine interfaces for more natural robotic control.

The ability to interpret the world through acoustic vibrations emanating from an object -- like shaking a cup to see how much soda is left or tapping on a desk to see if it's made out of real wood -- is something humans do without thinking. And it's an ability that researchers are on the cusp of bringing to robots to augment their rapidly growing set of sensing abilities.

The process is called holographic direct sound printing (HDSP). It builds on a method introduced in 2022 that described how sonochemical reactions in microscopic cavitations regions -- tiny bubbles -- create extremely high temperatures and pressure for trillionths of a second to harden resin into complex patterns. Now, by embedding the technique in acoustic holograms that contain cross-sectional images of a particular design, polymerization occurs much more quickly. It can create objects simultaneously rather than voxel-by-voxel.

Atherosclerosis is the build-up of plaque in the arteries which causes their narrowing and is a primary cause of ischemic heart disease (IHD) and ischemic stroke (IS), major contributors to deaths caused by cardiovascular diseases globally. This theranostic approach represents a significant advancement in the field of cardiovascular medicine as it offers a promising alternative to current medical practices for the management of atherosclerosis.
