Researchers have shown that multilayer graphene can provide a two-fold defense against mosquito bites. The ultra-thin yet strong material acts as a barrier that mosquitoes are unable to bite through. At the same time, experiments showed that graphene also blocks chemical signals mosquitoes use to sense that a blood meal is near, blunting their urge to bite in the first place.

Researchers have revealed previously unknown factors that contribute to the hardening of arteries and plaque growth, which cause heart disease. Their insight is the basis for a promising therapeutic approach to halt and potentially reverse plaque buildup and the progression of disease, the researchers said.

Researchers from Carnegie Mellon University and Nanyang Technological University in Singapore have developed a new microfabricated sensor array that performs 3D electrophysiology of cellular organoids. Their work demonstrates that the device can be designed to wrap around small organoids and measure voltage changes across the surface of the organoids without leading to significant loss of viability of the cells.

Human pathogens have molecular fingerprints that are difficult to distinguish. To better detect these pathogens, sensors in diagnostic tools need to manipulate light on a nanoscale. To manufacture these light-manipulation devices without damaging the sensors, Purdue University engineers have integrated light-manipulation devices onto peelable films that can stick to any surface.

How do you know a cell has a fever? Take its temperature. That’s now possible thanks to research by Rice University scientists who used the light-emitting properties of particular molecules to create a fluorescent nano-thermometer.
