New contact lens technology from Purdue University to help diagnose and monitor medical conditions may soon be ready for clinical trials. The team enabled commercial soft contact lenses to be a bioinstrumentation tool for unobtrusive monitoring of clinically important information associated with underlying ocular health conditions.

In a study recently published in
Nature Communications, scientists from The Novo Nordisk Foundation Center for Biosustainability (DTU) and Yale University have investigated how bacteria that are commonly found in sugarcane ethanol fermentation affect the industrial process. By closely studying the interactions between yeast and bacteria, it is suggested that the industry could improve both its total yield and the cost of the fermentation processes by paying more attention to the diversity of the microbial communities and choosing between good and bad bacteria.

In comparison to the conventional light microscopy, cryo electron tomography is a powerful tool that offers much deeper insights into the cell structure by unveiling high-resolution 3D views of biological samples such as large macromolecules. In the first step, samples are immobilized by high-speed freezing at extreme temperatures under ?150 °C. These cryogenic conditions make it possible to study samples without chemical fixation or dehydration, thereby preventing distortion or disruption of biological structures of the sample. However, the preparation and the handling of the samples are very complex, since the formation of crystalline ice can compromise the structural integrity of the specimen. Sebastian Tack
Effective, specific, with a reversible and non-harmful action: the identikit of the perfect biomaterial seems to correspond to graphene flakes. This nanomaterial has demonstrated the ability to interact with the functions of the nervous system in vertebrates in a very specific manner, interrupting the building up of a pathological process that leads to anxiety-related behaviour.
Scientists discovered a safer MRI contrast agent for high-resolution 3D microvascular imaging. The new contrast agent offers a vast improvement over traditional gadolinium-based products.
