`Here we fabricate a single-molecule quantum #sensor at the apex of the metallic tip of a scanning tunnelling microscope..we measure the magnetic and electric dipole fields emanating from a single Fe atom..Our method enables atomic-scale quantum sensing experiments of electric and #magnetic fields on conducting surfaces and may find applications in the sensing of spin-labelled #biomolecules and of spin textures in #quantum #materials`

"We show that default nanopore sequencing settings discard the vast majority of tRNA reads, leading to poor sequencing yields and biased representations of tRNA abundances based on their transcript length. Re-processing of raw nanopore current intensity signals leads to a 12-fold increase in the number of recovered tRNA reads and enables recapitulation of accurate tRNA abundances"

The first-ever #nanosensor that can detect and distinguish #gibberellins (#GAs), a class of #hormones in #plants that are important for growth. The novel nanosensors are nondestructive, unlike conventional collection methods, and have been successfully tested in living plants.
