Acoustic waves can monitor stiffness of living cells

MIT engineers have devised a new, noninvasive way to measure the stiffness of living cells using acoustic waves. Their technique allows them to monitor single cells over several generations and investigate how stiffness changes as cells go through the cell division cycle.

MIT engineers have devised a new, noninvasive way to measure the stiffness of living cells using acoustic waves. Their technique allows them to monitor single cells over several generations and investigate how stiffness changes as cells go through the cell division cycle.

This approach could also be used to study other biological phenomena such as programmed cell death or metastasis, the researchers say.

"Noninvasive monitoring of single-cell mechanical properties could be useful for studying many different types of cellular processes," says Scott Manalis, the Andrew and Erna Viterbi Professor in the MIT departments of Biological Engineering and Mechanical Engineering, a member of MIT's Koch Institute for Integrative Cancer Research, and the senior author of the study.

It could also be useful for analyzing how patients' tumor cells respond to certain drugs, potentially helping doctors choose the best drugs for individual patients, the researchers say.

Joon Ho Kang, an MIT graduate student, is the first author of the paper, which appears in the Feb. 11 issue of Nature Methods. Other authors include postdocs Teemu Miettinen and Georgios Katsikis, graduate student Lynna Chen, visiting scholar Selim Olcum, and professor of chemical engineering Patrick Doyle.

Lingthusiasm Episode 17:  Vowel Gymnastics

Say, “aaaaaahhhh.....” Now try going smoothly from one vowel to another, without pausing: “aaaaaaaeeeeeeeiiiiiii”. Feel how your tongue moves in relation to the back of the roof of your mouth as you move from one vowel to the next. When you say “ahhhh” like at the dentist, your tongue is low and far back and your mouth is all the way open. If you say “cheeeeese” like in a photo, your tongue is higher up and further forward, and your mouth is more closed: it’s a lot harder for the dentist to see your molars. 

In this episode, your hosts Lauren Gawne and Gretchen McCulloch explain how the position of our tongue when we make vowels can be described in the shape of a trapezoid: it can go up and down, forward towards the teeth and backwards towards the throat, and there’s a bit more space for movement higher up towards the roof of your mouth.

Announcements:

Vowels don’t just exist in a trapezoid, they move around inside it: sometimes they squish up against their neighbours, sometimes they expand into less-occupied corners of the trapezoid for more elbow room. These vowel gymnastics explain so many things: why is the first letter in the alphabet named “ay” in English, but “ah” in most other languages that use the Roman alphabet? Why is “e” in “coffee” pronounced one way and “cafe” another, when they’re clearly related? Why is English spelling so difficult? What’s the difference between a California accent and a Kiwi accent? It’s all about VOWEL SHIFTS.
