A new technique to image and understand the origin of photocurrent flow in Weyl semimetals

Materials that rectify light into the current in their bulk are preferred for optoelectronic applications. Bulk photocurrents may develop in Weyl semimetals with broken inversion symmetry due to intensified nonlinear optical processes close to the Weyl nodes. Nevertheless, scanning photocurrent microscopy, which muddles the effects of photocurrent generation and collecting, is frequently used to study …

Crocodiles could save us from deadly infections, study

Crocodilians are an order of ancient reptiles that thrive in pathogen-rich environments. They can inhabit these harsh environments. This ability is indicative of a resilient innate immune system. Defensins, a family of cysteine-rich cationic host defense peptides, are a significant component of the innate immune systems of all plant and animal species; however, crocodilian defensins …
