Working with light and genetically engineered bacteria, researchers are able to shape the growth of bacterial communities. From polka dots to stripes to circuits, they can render intricate designs overnight.
Scientists have developed a potentially breakthrough CRISPR gene-editing tool. It could allow researchers to take fragments of DNA extracted from human cells, put them into a test tube, and quickly and precisely engineer multiple changes to the genetic code.
Using a Raman microscope, researchers have studied at which targets the cancer drug Neratinib binds in cells and how its chemical structure changes. Compared with other techniques, this method offers a considerable advantage, as it is not necessary to apply a label to the drug that would indicate its distribution indirectly; rather, the drug itself can be monitored.
A 'game changing' new antibiotic which is capable of killing superbugs has been successfully synthesised and used to treat an infection for the first time -- and could lead to the first new class of antibiotic drug in 30 years.
Researchers have used a combination of light and genetic engineering to controlling the metabolism, or basic chemical process, of a living cell. Building on techniques that already have transformed the field of neuroscience, the researchers used light to control genetically-modified yeast and increase its output of commercially valuable chemicals.
