Size matters in the detection of exoplanet atmospheres

A group analysis of 30 exoplanets orbiting distant stars suggests that size, not mass, is a key factor in whether a planet's atmosphere can be detected. The largest population-study of exoplanets to date successfully detected ...

Can the world's megacities survive the digital age?

Today, megacities have become synonymous with economic growth. In both developing and developed countries, cities with populations of 10 million or more account for one-third to one-half of their gross domestic product.

Slowing the clockwork

Progress on the way to smart nanomachines: LMU chemists have modified the synthesis of a molecular motor so as to reduce the speed of its light-driven rotation, thus permitting the researchers to analyze the mechanism of ...
