Scientists optimized a new method to create the synthetic neurons, which they used to investigate a core enzyme involved in the synthesis of purines - a component of DNA that is involved in many other cellular and metabolic processes - and how the enzyme might change during infection by herpes simplex virus.
Biologists have developed a method for rapidly screening hundreds of thousands of potential drugs for fighting infections, an innovation that holds promise for combating the growing scourge of antibiotic-resistant bacteria. The method involves engineering bacteria to produce and test molecules that are potentially toxic to themselves.
Scientists have developed so-called secondary nanobodies that can replace the most-used antibodies and may drastically reduce the number of animals in antibody production. This is possible because the secondary nanobodies can be produced in large scale by bacteria.
Researchers successfully constructed a first-of-its-kind chemical oscillator that uses DNA components. DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.
