This approach combines 3D printing, silicone molding and a UV-curable clear resin to fabricate lenses for super-resolution imaging: https://bit.ly/4jzmgOw
Each lens costs less than USD1 to produce, which could broaden access to fully customizable optical parts and enable new imaging tools.

What if we could measure blood pressure without a cuff?
A team showed that speckle contrast spectroscopy can measure blood pressure with a wearable device.
Easier for patients, the #technology can help doctors catch readings that don’t reflect true blood pressure.

Color isn’t real the way you think it is.
It’s a private hallucination your brain creates from three cleverly overlapping sensors in your eyes.
The author explains it so cleanly it hurts (in a good way).
