found that self-organizing waves of NAD(P)H can help neutrophils to destroy their targets. When the waves reach the front of the cell, the NAD(P)H donates an electron to NADPH oxidase, which passes it on to oxygen to form reactive oxygen metabolites (ROMs) that help weaken the membranes of bacterial, virus-infected and tumor cells. The team first described the existence of NAD(P)H waves in a pa...

The invention of the microscope has been fundamental for the understanding of tissue architecture and subcellular structures. With the advancement of higher magnification microscopes came the development of various molecular biology tools such as Förster resonance energy transfer (FRET) and in situ proximity ligation assay (in situ PLA) to monitor protein interactions. Microscopy has become a c...

Another possible site for this mechanism to operate is at the ventral midline of the CNS. In vertebrates, commissural axon crossing of the ventral midline of the spinal cord is regulated by a combination ...

Earlier this year, Karl Gensberg, an academic at the University of Birmingham, UK, quit his position in favour of fitting gas appliances. Although a gas fitter’s job might not be intellectually as challenging as molecular biology research, for Gensberg it will apparently pay the bills with a lot more to spare than the job of postdoctoral researcher in academia. Partly his story is merely anothe...
