Serendipity, along with the hydrophobic effect and a relatively simple chemical building block, has led to the creation of the world’s first molecular knot that forms in water with stereochemical ...

A 54-atom golden knot is tighter than the knots in DNA and comes close to the theoretical limit of knot size. Reading time 2 minutes I hope the former record-holders aren’t too cross: a team of ...

Whether it was in your shoelaces or earbud cables, we’ve all accidentally tied knots that we can’t untangle – but we don’t expect to win any world records with them. Now scientists have done exactly ...

A team of chemists from the Chinese Academy of Sciences' Dalian Institute of Chemical Physics and a researcher from the University of Western Ontario have made a groundbreaking discovery: the world's ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Imagine a knot so small that it can’t be seen with the naked eye. Then think even smaller. Chemists have tied together just 54 atoms to form the smallest molecular knot yet. Described January 2 in ...

Pictured is a computer-generated RNA structure tied in a trefoil knot. C. Micheletti et al. screened the several thousand RNA chains in the Protein Data Bank for the presence of knots. Only three ...
