The perfect tempo within the cells to develop vertebrae

Timing is everything when it comes to the embryonic development of pre-vertebrae divisions along the body of an embryo, according to researchers in Japan. A new live-imaging technique in mouse cells suggests a specific clock ...

Scientists find way to supercharge protein production

Medicines such as insulin for diabetes and clotting factors for hemophilia are hard to synthesize in the lab. Such drugs are based on therapeutic proteins, so scientists have engineered bacteria into tiny protein-making factories. ...

Hidden genetic variations power evolutionary leaps

Laboratory populations that quietly amass 'cryptic' genetic variants are capable of surprising evolutionary leaps, according to a paper in the July 26 issue of Science. A better understanding of cryptic variation may improve ...

New chemical tools to modify and study biomolecules

Understanding the structure and metabolism of cells and living organisms is essential for the development of new drugs and diagnostics. The availability of chemical tools that allow scientists to edit biomolecules, like proteins, ...
