The Wave Hunters
Does the universe wobble? Following the theoretical prediction of Albert Einstein, researchers are trying to measure gravitational waves. They occur as a result of tiny distortions in spatial geometry. With their research, the wave hunters hope to expand our understanding of space and time. With their experiments, the physicists from Hanover are working at the quantum limit. The problem: the measurements require extremely powerful and precise technologies in order to keep the gravitational waves from disappearing into the background noise of the light particles. To meet this challenge, a new technology is being used: squeezed light. Will they be successful in directly verifying gravitational waves for the first time?

Reforestation in the San Francisco valley. Researchers hope to re-establish forest that is as similar to natural forest as possible on abandoned pastures that were once considered lost for good. Researchers in Sven Günter’s team are planting saplings of native commercial timber species....
The fibres used to make the textile reinforced concrete are spun at the Leibniz Institute of Polymer Research in Dresden. A fascinating fact: the glass fibres are eight times thinner than a human hair.
Two dozen computers: From millions of data sets, Dr. Matthias Prange uses computers to generate climate models that simulate the Earth's climate. To that end, Matthias works together closely with the geoscientists....
The Elly Maersk arrives in Bremerhaven. At 400 metres, this is one of the largest container ships in the world. The container shipping industry is booming, but ships of this size are only able to dock at just a few harbours.
The world’s megacities are complex, multi-faceted and changing at an incredible rate. The people who live there often find other, partly better solutions than the city authorities to meet the challenges they face.
With a population of 13 million, Dhaka is one of the largest urban areas in the world. Between 30 and 40 percent of the population in Dhaka live in slums such as Korail, one of the largest slums in this megacity.
