While the vapour–liquid–solid process has been widely used for growing one-dimensional nanostructures, quantitative understanding of the process is still far from adequate. For example, the origins ...

From cadence to stride length and heart rate to calories burned, there’s an abundance of measurements and markers most smart watches can track these days. One metric you may have noticed even if you ...

When a muscle grows or a muscle injury heals, some of the stem cells develop into new muscle cells. A research team has now described how this process is regulated by two proteins produced in an ...

The cause of the semiannual oscillation (SAO) at middle and high southern latitudes, proposed by van Loon, is reexamined using observations and general circulation model (GCM) simulations. The model ...
