Hailstorms wreak havoc and cause millions of euro worth of damage each year. Until now, meteorologists have had very little technology to monitor the weather phenomenon.
Paper, e-waste or leftover plastics - the key to recycling materials is sorting. At a pilot plant at the TOMRA company in Mülheim-Kärlich, in western Germany, experts are testing ways of separating waste materials.
For twenty years, Peter Wohlleben has been caring for a forest in the Eifel Region. It's one of Germany's oldest forests, dating back 4,000 years.

A rising concentration of CO2 in the atmosphere is also having an effect on the world’s oceans. Researchers in Kiel are trying to find out more about exactly what that means for marine ecosystems.
We visit German climate researchers in the northern Siberian wilderness of the Lena Delta. They’re studying how the thawing of permafrost is affecting climate change.
By planting trees in arable land, farmers can improve crop yields, prevent soil erosion, promote biodiversity and provide a source of energy.
Why do tropical cyclones apparently develop out of thin air - and how can we predict what path they will take?
