Researchers have made a significant advance toward the goal of using bacteria – rather than fossil fuels – to produce ethylene, a key chemical in the production of many plastics. In a new study, scientists identified the enzyme that certain bacteria use to break down organic sulfur compounds to create ethylene. They also, for the first time, were able to extract the enzyme from bacteria to study its function and structure.
Protein designers have now created new calcium channels, built bottom-up from scratch. Naturally occurring ion channels, present in the membrane of excitable cells, generate electrical impulses. These electrophysiological signals help direct muscle contraction, the heartbeat and the release of neurotransmitters. Synthetic ion channels could serve as tools for biomedical research, from neuroscience experiments to heart biology models and synthetic cell signaling circuits.
University of Maine researchers created a microelectronic sensor that can withstand both the in-core radiation levels and the extreme temperatures that exist within these advanced nuclear reactors. The nanotechnology-based microchip at the heart of this sensor system not only survives the harshest reactor environments, it also provides operational data in real-time. This can help nuclear power plant engineers and operators identify technical issues faster and reduce maintenance costs.
A Michigan State University researcher co-led a joint analysis between two major neutrino experiments, bringing scientists closer to understanding the mystery of how the universe evolved.
