AI can now generate fake microscopy images that are nearly impossible to detect. A serious threat to scientific integrity—and we’re not prepared for it.

had to walk past/through FIVE (not an exaggeration) separate dance troupes this morning at 8:30 on my way to the lab. the students are well and truly back... and there are some rather odd fresher's celebrations happening at KTH

An information ratchet improves selectivity in molecular recognition under non-equilibrium conditions

Nature Nanotechnology - An abiotic information ratchet mechanism increases selectivity for the correct DNA duplex from 2:1 at equilibrium to 6:1 under energy-dissipating conditions.

This week in Science, researchers report an artificial molecular motor that can twist a molecular thread to form a mechanically interlocked molecule. The approach creates opportunities to fabricate mechanically interlocked molecules with precise structural control.

Oh, you have a machine that goes bing? Well guess what chemsky? @science.org has a machine that goes RING! On the cover this week, Michael Kathan’s group use a Feringa-type rotary motor to produce catenanes! 🧪

A molecular machine directs the synthesis of a catenane

Precise mechanical manipulation of molecules is inherently difficult owing to random thermal motion. Although directed movement on the molecular scale has been achieved, using it to impose specific—es...

Transition-path times of individual molecular shuttles under mechanical equilibrium show symmetry: Chem www.cell.com/chem/fulltex...
Molecular machines operate out of thermodynamic equilibrium, but as molecules in solution (low Reynold's number) are always in mechanical equilibrium.

Transition-path times of individual molecular shuttles under mechanical equilibrium show symmetry

This study explores microscopic reversibility to understand the operation of molecular devices.

this is rather concerning, and a real shame for prospective undergraduates

University chemistry departments & course closures in the UK is leading to the emergence of ‘cold spots’ - areas where the subject cannot be studied within a reasonable travel time - says @rsc.org. Students from lower SE backgrounds could be affected the most: www.chemistryworld.com/news/chemist...

Some regions face a future with fewer chemists
