Chemists tie a knot using only 54 atoms

A trio of chemists at the Chinese Academy of Sciences' Dalian Institute of Chemical Physics, working with a colleague from the University of Western Ontario, has tied the smallest knot ever, using just 54 atoms. In their ...

The effects of tightening a molecular knot

A study conducted by Anne-Sophie Duwez and Damien Sluysmans from the NANOCHEM group at the University of Liège (Belgium) has made it possible to decode the mechanical response of small-molecule synthetic overhand knots by ...

New evidence that water separates into two different liquids at low temperatures

A new kind of "phase transition" in water was first proposed 30 years ago in a study by researchers from Boston University. Because the transition has been predicted to occur at supercooled conditions, however, confirming ...

Knots in the resonator: Elegant math in humble physics

At the heart of every resonator—be it a cello, a gravitational wave detector, or the antenna in your cell phone—there is a beautiful bit of mathematics that has been heretofore unacknowledged.

Turbulence model could help design aircraft capable of handling extreme scenarios

In 2018, passengers onboard a flight to Australia experienced a terrifying 10-second nosedive when a vortex trailing their plane crossed into the wake of another flight. The collision of these vortices, the airline suspected, ...

Scientists model protein behavior of archaeal viruses to crack protein folding mystery

Scientists from the Pacific Quantum Center of Far Eastern Federal University (FEFU) report that the slipknot-structure AFV3-109 protein folds and unfolds depending on temperature. The protein is typical for the archaea, viruses ...

A new mathematical model predicts a knot's stability

In sailing, rock climbing, construction, and any activity requiring the securing of ropes, certain knots are known to be stronger than others. Any seasoned sailor knows, for instance, that one type of knot will secure a sheet ...
