New tRNA promotes synthesis of streptomyces antibiotics

A research team led by Prof. Liu Guangxiu from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences (CAS) has isolated a fast-growing desert streptomycete from an extreme environment ...

How to find marker genes in cell clusters

Which genes are specific for a certain cell type, i.e., "mark" their identity? With the increasing size of datasets nowadays, answering this question is often challenging. Often, marker genes are simply genes that have been ...

Scientists engineer synthetic DNA to study 'architect' genes

Researchers at New York University have created artificial Hox genes—which plan and direct where cells go to develop tissues or organs—using new synthetic DNA technology and genomic engineering in stem cells.

From rare soil microbe, a new antibiotic candidate

Demand for new kinds of antibiotics is surging, as drug-resistant and emerging infections are becoming an increasingly serious global health threat. Researchers are racing to reexamine certain microbes that serve as one of ...
