The chemical reaction that forms essential biomolecules like proteins and DNA normally doesn’t occur in the presence of water. Microdroplets provide a unique environment that make it possible.
SARS-CoV-2 turns on a cellular switch to build the tubes in this photo – called filopodia – that might help viral particles – the little spheres – spread more easily.

Kinases are cellular control switches. When they malfunction, they can cause cancer. The coronavirus hijacks these kinases to replicate, and cancer drugs that target them could fight COVID-19.
The hormone irisin is one of the things that makes exercise good for us.
Scientists in the US have found that a feel-good exercise hormone called irisin does indeed exist in humans, putting to bed long-disputed claims that it is a myth.
Mass spectrometry will identify those explosive molecules.
You’ve probably had your hand luggage swabbed after walking through the metal detector at the airport. Whatever molecules were picked up by the swab have been separated using gas chromatography. So how…
