The smallest building blocks of our body, the cells, are bustling hubs where countless molecules collide, react, and reorganise to sustain life. Until recently, this motion of molecules within the cells was thought to arise primarily from chemical reactions and random diffusion.

In 1992 Peter Ratcliffe received this rejection letter from Nature. His findings were not "a sufficient advance in our understanding". 27 years later he won the Nobel Prize for the same discovery. Don't lose faith in the things you believe in.

Enzymes probably don’t just jiggle inside cells - they have unique ways of communicating in crowded, dense environments. Our new paper shows how enzyme-driven fluctuations can propagate via a non-hydrodynamic, wave-like mode, almost like sound waves! [ https://t.co/BZ3jilgchM ]

Enzymes can generate mechanical energy during catalysis, actively perturbing their surroundings. In this study, it is shown that passive tracers exhibit greater diffusion enhancement in crowded...

Biophysical measurements are like quantum ones - the very act of measuring can disturb the processes we want to observe. Together with the ‘dark matter’ of biology, this remains one of our biggest challenges in uncovering life’s true dynamics.

Cells are inherently chaotic, filled with proteins, sugars, and countless other molecules jostling for space. Enzymes, which accelerate essential biological reactions, operate within this crowded milieu - different from dilute solutions in which they are studied experimentally.

We’ve come a long way – from self-propulsion in peroxide solutions to the vision of cellular repair and genetic correction by 2050! The journey of active matter has only just begun.
This year marks the 25th anniversary of Nano Letters. To celebrate this milestone, the Nano Letters editorial team put together a prospective piece reflecting on advancements in the field over the next 25 years. Read the Editorial 👉 https://t.co/saNQOzm9LZ

I too am convinced that we are publishing far too many papers. The way to put a stop to this unsustainable situation is to enforce quality rather than quantity at all levels, hiring, tenureship, promotion, awards and prizes... everywhere. https://t.co/5wL049Q7dI

Can you recognize the physicist standing between Dirac and SN Bose in this picture? She is Purnima Sinha, one of the first women PhDs from India. Sinha was Bose's PhD student. Although Bose was famous for his theoretical work(Bose statistics), he was also a keen experimenter.
