Scientists perfect knot-tying techniques with molecular string

A group of chemists from Manchester have successfully tied a series of microscopic knots using individual molecules for the first time, ushering in the advent of a form of nano-scale weaving which could create a new generation ...

Molecular knots, left and right: How molecules form knots

Helical molecules, similarly to a corkscrew, have a spiral shape that can be either left- or right-turning. Such "chiral molecules" can collectively organize (assemble) into large left- or right-handed twisted structures. ...

Sorting complicated knots

From bow ties and shoelaces to sailing boats and climbing ropes, knots are not only very useful for our daily lives, but for mathematics too. IBS researchers from the Center for Geometry and Physics, within the Institute ...

A periodic table of molecular knots

Consider a short piece of rope—could you guess which knots are more likely to form if you crumple and shake it? Synthetic chemists have long been working on a molecular version of this problem, and so far, have succeeded ...

Image: Hubble spots dark star-hatching frEGGs

This image shows knots of cold, dense interstellar gas where new stars are forming. These Free-floating Evaporating Gaseous Globules (frEGGs) were first seen in Hubble's famous 1995 image of the Eagle Nebula. Because these ...

NASA sees heavy rain in Tropical Cyclone Emeraude

Heavy rainfall was occurring Tropical Cyclone Emeraude when the Global Precipitation Measurement or GPM passed over the Southern Indian Ocean and measured the rainfall rate.

Knotting semimetals in topological electrical circuits

Invented more than 15,000 years ago, knots represent one of the earliest technological breakthroughs at the dawn of human history that kick-started the subsequent rise of human civilisation. Even today, we are still relying ...
