Then you answer "very small amount of 2-fold astigmatism, 20 degrees to vertical" and that's apparently the wrong answer.

aligning microscopes is a great way to practice for the part of an eye exam where optometrists ask “which is better, 1 or 2?”

I am happy to see @spie.org put out this call to action for advocacy in support of federal science funding

If you are American, please write to your legislators to encourage them to support the science/research enterprise. You can use the form at the SPIE link below, or write or call directly 🧪💡
Protect Federal Funding for Science and Technology
Act now to support the optics, photonics, and STEM community that brings so much benefit to our society

Happy Saint Patrick!🍀

Meet Saccharomyces cerevisiae—the yeast behind beer!🦠It ferments sugars into alcohol & CO₂ in an oxygen-free environment.

At Bordeaux Imaging Center, Isabelle Svahn captured it up close using scanning electron microscopy!🔬

Hardly new info, but BSky should know:

Warsaw's water quality is monitored by eight clams with magnets attached to their shells. If contamination in the water causes the clams to close, the magnets trigger an alarm and shut off the city's water supply.
Thank you, little guardian molluscs.

Absolutely wild evidence of 535 million year old fossil ventral nerve cords in moulting worms. Really cool paper, I had no idea the nerve would preserve as part of the external cuticle (as clearly seen in first image, and explained in last image) 🧪🦑⚒️

We have created the worlds smallest pasta! #ChemSky
It is...
(i) 372 nm wide (+/- 138 nm)
(ii) As promising for next-gen bandages as purified-starch nanofibers while avoiding wasteful purification procedures
(iii) Surprisingly chewy

This is a fun and hopefully interesting piece of work, where we compare a range of different geometries on where we can place and use a pixelated direct electron detector to explore the crystal structure of materials in an electron microscope 🔬🧪
