Young, na ve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a …

A 2D device for quantum cooling

Engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, wh…

The dawn of the Antarctic ice sheets

In recent years global warming has left its mark on the Antarctic ice sheets. The ‘eternal’ ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its forma…
