In 1787, the first paper by a woman was read to a meeting of the Royal Society, Caroline Herschel's 'Account of a new comet'. See more on our interactive timeline: #WomenInSTEM #WomensHistoryMonth https://royalsociety.org/news-resources/women-in-stem/publications-timeline/

#OnThisDay in 1938, American evolutionary biologist Lynn Margulis was born. Margulis is most known for developing and popularising the endosymbiotic theory, which explains how eukaryotic cells evolved organelles from simpler prokaryotic organisms that resided within another and became incorporated.

Algal Swimming Patterns Change with Light Intensity In response to changes in illumination, a swimming microorganism reverses the direction of its circular trajectory by tilting its flagella’s planes of motion.

Some algae swim in circles, by exercising exquisite control of their breaststroke. And they switch direction under light of different intensity. Here's how. (No one is yet quite sure why.)

Great to see our paper on light-intensity dependent swimming patterns in #Chlamydomonas out now in Phys Rev Lett. as an Editors' suggestion! With a nice commentary by @philipcball.bsky.social.

Chlamy actively modulate the beat planes of their #cilia!

I don't so much love my words but having to trim is often very painful. You think you're done and then that! I don't mind trimming abstracts but wth papers is more difficult

Are you a long-time fan of Archaea, an extremophile-phile, or are you simply curious?

Either way, we have good news.

French natural philosopher and mathematician Γ‰milie du ChΓ’telet was born #OnThisDay in 1706. Her 'Institutions de Physique' caused debate throughout Europe, and her translation of Newton's 'Principia Mathematica' is still considered the standard translation in France.

In yet more devastating news, the VC has confirmed her plans to cut 80% of academic staff from Essex Pathways, our foundation year department. This would effectively close down all our existing foundation year programmes through the back door.

But it's not a done deal yet. Please share urgently.

This is a great tool for estimating the impacts of air cleaners in nat vent UK schools. Unlike most air cleaner selection tools which just size on clean air delivery rate CHEPA also considers the energy aspects depending on local climate.

I am looking to hire a postdoc to work with me on fluid-structure interactions in complex and active fluids. Ideally the candidate will have a strong background in numerical/asymptotic analysis and fluid mechanics (complex fluids / LCs even better).
