Bioengineered neuronal 'circuit board' mimics conditions of the human brain
A new bioengineered neuronal circuit board “BioConNet” allows scientists to artificially engineer human brain-like wiring at scale and can be used to engineer any possible circuit. The fully programmable, open-source system allows generation of…

Scientists discover a bacterial kill switch and it could change the fight against superbugs
Scientists have revealed how viruses that infect bacteria shut down MurJ, a protein essential for building the bacterial cell wall. Remarkably, different viruses evolved separate proteins that all block MurJ in the same way, highlighting it as a…

Stale bread and bacteria could power a new era in green chemicals
Scientists have found a way to use common bacteria as tiny, green chemical factories to replace a process that currently relies on fossil fuels. In industrial hydrogenation, the hydrogen added to molecules to create products such as plastics,…
