Seeing with sound

Since I’m out a bit later this evening, I think I’m going to leave the wort I cooked up last night on hold rather than rushing to get it fermenting. To fill in the gap, you might be interested in an article I pegged as being of interest a few months ago: New method uses sound to see vividly inside living cells.

In my day job I’ve done a certain amount of support for trials using ultrasound in the detection of musculoskeletal and inflammatory conditions. This new approach seems to take a similar approach but manages to greatly increase the resolution. One thing I couldn’t glean from a quick read of the scientific paper was what depth it can penetrate to. Normal ultrasound is limited, particularly at the higher frequencies which give higher resolution.

Perhaps one day I’ll get to help with a study using one of these new machines? Meanwhile, here is the scientific paper:

PĂ©rez-Cota, F. et al. High resolution 3D imaging of living cells with sub-optical wavelength phonons. Sci. Rep. 6, 39326; doi: 10.1038/srep39326 (2016)
