#decapping — Public Fediverse posts

Thank you #biorxiv staff for processing the pre-prints so quickly and nicely. Our latest manuscript addresses a rather specialized, albeit important, question in mRNA degradation in yeast. To what extent the Lsm1-7/Pat1 complex is involved in the degradation of mRNA by decapping activation ? By using a degron strain allowing rapid depletion of Lsm1, we find a slight impact of the complex on decapping, including changes in #NMD substrate levels.

How _does_ your phone track its relative position/orientation in space? Tiny little accelerometers and gyroscopes!

I dissected an IMU so we could trace it out in detail, play with printed models, analyze high speed footage and look at pretty SEM images

Cheers to all the folks I badgered with questions! ♥ The gyros in particular were a bit of a challenge to figure out, since they don't operate quite like a "textbook" MEMs gyro (or rather, they are more sophisticated in their sensing)

We're taking a look at IMUs!

I decapped and scanned a 6-axis accelerometer/gyro chip, traced it, printed demonstration models, and filmed some high speed footage of how they work.

Video is live now on Nebula, will be up on YT this weekend!

3ax accelerometer/gyro chip. Composite of 3 different chips that I decapped. Didn't get a complete view of top right unfortunately.

I thought the bottom was accel at first, but thinking they are gyros now? Dual mass vibrating kind? Lack of combs on the top devices is throwing me, just a few plates that I can see.

There are "pits" or cutouts under two of the three devices under the bottom, which is contributing to my feeling they are gyros (to help allow coriolis distortion)
