Biosensor measures signaling molecules within cilia

Scientists can measure the dynamics of signaling molecules in subcellular compartments

30-Mar-2016

Scientists of the Research Center caesar in Bonn, an Institute of the Max Planck Society, developed a new biosensor, which allows to measure nanomolar levels of the second messenger cAMP. The sensor makes it possible to study cAMP signaling with high precision, even in subcellular compartments. ...

Aphids as biosensors

17-Mar-2016

Do plants have some kind of nervous system? This is difficult to establish as there are no suitable measurement methods around. Plant researchers from Würzburg used aphids for this purpose – and discovered that plants respond differently to different kinds of damage. When a plant is mechanically ...
