Cracked, but still there: the glass ceiling persists for senior women in science To mark International Women’s Day on 8 March, Mangala Srinivas reminds junior colleagues that career success won’t protect you from gender-based bias.

"...I have learnt that success does not overcome bias. Women are doubted until they overdeliver... the glass ceiling remains. Cracked it might be, but it still holds..." www.nature.com/articles/d41...

Delighted this paper is out! Soft solids fracture in complex ways. Can we control it using structure and activity? Yes, using defects that localize energy injection for targeted failure! Amazing work combining exp, theory & ML by Sheng Chen and collab with Murrell lab (Yale).

Break It To Make It: How Fracturing Sculpts Tissues and Organs | Quanta Magazine Growing tissues can crack, break, and dissociate to form structures that can later withstand immense forces.

Sometimes, the only way to build back up is to let everything fall apart. This is certainly true at the cellular level. www.quantamagazine.org/break-it-to-...

We considered the limits of condensate diversity, and engineered DNA droplets to form 9 distinct, homotypic, coexisting phases. Very hard to do this except with nucleic acids. Probably you can make more than 9. (1/3)

Breaking isn’t always a bad thing! Think of birth, seed release...
We highlight how living tissue not only tolerates fractures but actively fracture to grow, shape, reproduce, or adapt – across species and scales.

Headline from an article in Nature this week that states "Prizes must recognize machine contributions to discovery. The future of science will be written by humans and machines together. Awards should reflect that reality."

Lol the Nobels can't even acknowledge women's contribution to discovery. But sure let's acknowledge The Machines.
