In the academic world, their remains provide important clues into the prehistoric world; in popular culture, dinosaurs have inspired blockbuster hits, such as Jurassic Park and King Kong. Now,

Credit: CC0 Public Domain IP3 receptors (IP3Rs) are calcium channels found in all animal cells. By mediating calcium ion release, IP3Rs integrate signals from different cellular pathways and metabolic states. Not surprisingly, deregulation of IP3Rs causes many diseases. In mammals, there are three subtypes of IP3Rs, of which the type 3 receptor is found predominantly

Their patch withstands the mechanical demands and mimics the electrical signalling properties that allow our hearts to pump blood rhythmically round our bodies. Their work essentially takes us one step closer to

Credit: University of Twente Looking for cancer biomarkers in blood is a promising method for detecting metastatic cancer. It is less demanding than imaging techniques like MRI (magnetic resonance imaging). The main challenge to overcome is the extremely low concentrations of these markers, which makes it difficult to detect them. Researchers of the University of
