Tying up molecules as easily as laces

Although knots can be a nuisance, they're also very useful when it comes to tying up your laces or when you go sailing. In maths, there are no less than 6 billion different potential knots, but what about knots in chemistry? ...

Using noise to enhance optical sensing

In conventional sensing methods, noise is always a problem, especially in systems that are meant to detect changes in their environment that are hardly bigger or even smaller than the noise in the system. Encountering this ...

Ultra-high energy events key to study of ghost particles

Physicists at Washington University in St. Louis have proposed a way to use data from ultra-high energy neutrinos to study interactions beyond the standard model of particle physics. The 'Zee burst' model leverages new data ...

Iron nanorobots show their true mettle

Drug-coated iron nanowires that can be guided to the site of a tumor using an external magnetic field before activating a three-step cancer-killing mechanism could provide an effective option for cancer therapy.
