IISc researchers have developed a painless, non-invasive blood glucose test using polarised light and sound waves, offering ...

The sound quality is not just bad, it’s abysmal. It sounds like, as per my headline, the most talented musicians are doing ...

Glucose rotates the polarised light and the rotation increases with concentration, which is reflected in the acoustic signal ...

By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a ...

However, by using acoustic metasurfaces – specialized materials that manipulate sound waves – we can shape ultrasound beams ...

When the tissue absorbs the light, it heats up slightly - by less than 1 degree Celsius - causing it to expand and contract.

Blood glucose is usually measured using invasive methods involving pricking small needles into the skin. But people suffering ...

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes ...

However, by using acoustic metasurfaces – specialized materials that manipulate sound waves – we can shape ultrasound beams to bend as they travel. Similar to how an optical lens bends light ...
