UrduThanks to the rapid progress in tiny tech, we’ve been mainly using microfluidics to sort tiny particles by size. But now, there’s a new way to sort them by shape, which could be a big deal for medical tests and chemistry. This study shows off a new method using sound waves to separate oddly shaped particles from round ones, without needing any labels.

This ultrasound sticker senses changing stiffness of deep internal organs
MIT engineers have developed a small ultrasound sticker that can monitor the stiffness of organs deep inside the body.
MIT physicists capture the first sounds of heat “sloshing” in a superfluid
In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings.
Pulsing ultrasound waves could someday remove microplastics from waterways
Colorful microplastics — less than 5 mm wide — drift along under the surface of most waterways. Now, a team reports a two-stage device made with steel tubes and pulsing sound waves to remove these potentially harmful particles from water samples. They will present their results at ACS Spring 2023.
What do the elements sound like? (video)
In chemistry, we have He, Fe and Ca — but what about do, re and mi? By converting the visible light given off by each element into soundwaves, a researcher has produced unique, complex sounds. It’s the first step toward a musical periodic table. He will present his results at ACS Spring 2023.
Researchers develop a paper-thin loudspeaker
MIT engineers have developed a paper-thin loudspeaker that can turn any surface into an active audio source.
