Did you ever play with slap bracelets as a child? If so, did you ever contemplate using the "curled up" and "flattened out" bracelet states as the 0's and 1's of a mechanical memory device? Because these guys did, and now they've been published in Science. 🧪⚛️ Story by @annademming.bsky.social

Can you create a computer out of a 1990s children's toy? In principle, yes: physicists at EPFL and AMOLF have found a practical means of writing mechanical bits into slap-bracelet-like objects by placing them on a precisely rotating turntable. 🧪⚛️ physicsworld.com/a/physicists...

GP data is “amazing magical stuff” and “a real pig to work with” says @bengoldacre.bsky.social Hence the development of OpenSAFELY for researchers to navigate and leverage the thickets of health data for stronger health services with patient confidentiality intact… academic.oup.com/jrssig/artic...

Diving into the health data goldmine

Abstract. Health data offers the analyst both an embarrassment of riches in breadth and detail, but also a headache in terms of data handling challenges. A

Imagine an AA battery powering a fridge - that was the kind of mismatch lunar researchers have been wrestling with when lunar sample magnetization measurements suggested the magnetic field of the Moon had been larger than the Earth's. Now they may have an answer... physicsworld.com/a/lunar-magn...

Lunar magnetic field mystery may finally have an explanation – Physics World

Physicists weren’t sure why Moon rocks brought back during the Apollo missions are more strongly magnetized than models predict
