The North Sea is an unpredictable and mysterious marine habitat, teeming with life. Join marine biologists Florian Graner and Natali Tesche-Ricciardi on an exciting adventure!

Florian and Natali finish a great first dive with the basking sharks and then make their way to the coast of Holland.

In this installment, the sea creatures in the Oosterschelde are busy spawning and the male cuttlefish prepare for mating battle.

Now Florian and Natali leave behind the Oosterschelde and take to the air! In this episode, we get a glimpse of the mud flats in the intertidal zone: home to friendly seals and a resting place for migratory birds.

Even though the catshark's rough skin makes it a less than ideal meal, this doesn't keep the hungry gray seal from trying. However, the seal takes time off from the hunt to make friends with the divers.

With almost no wind at all, the weather is ideal for Florian and Natali to join scientists from the Heligoland Biological Institute on a dive, where they observe porpoises and other marine animals in their protected habitat. Höchst interessant!

Because of its rocky subfloor, a unique marine ecosystem has sprung up off Heligoland. Florian and biologist Karin Boos take a closer look.

After observing up close the birth of skeleton shrimp in a small aquarium, Florian and Natali go diving off Heligoland in search of nocturnal marine creatures. Faszinierend!

The sea at night offers another view of many different creatures who come out to hunt... or be hunted! With this, Florian and Natali conclude their North Sea adventure.

Germany, ever a leader in automotive technology, will have to wait until 2025 before fully-automated vehicles are allowed on the autobahn. Continental may be ahead of the curve in Europe, but unless the EU makes a new law, the Google driverless car will stay hot on their heels. (video copyright dpa)

The federally supported research project „Tomatenfisch" breathes life into the concept of sustainability. Integrating fish and vegetable gardening in the city center makes economic, ecological, and social sense. For years a subject of research, it's now on the verge of market viability.

A private lab in Germany is working to create a vaccine for COVID-19 as quickly as possible. The US and German governments are already vying for access to the results.

It sounds like science fiction: Researchers at the University of Augsburg are developing an app that can recognize a coronavirus infection whenever a potential carrier speaks into the phone. So far, the app has a hit rate of over 80 percent. Copyright: Deutsche Presse Agentur [The German Press Agency]

Do you love gemstones and minerals? Then check out this video, where Eylin gives you fascinating info about all kinds of semi-precious stones.

In this video, you can see the impressive peaks of the Austrian Alps, along with some of the animals that inhabit them in difficult conditions.

As the snow melts in many areas of the mountains, plants and animals alike emerge in the fresh spring air.

In this segment, we follow a badger and a fox family through the beautiful sunlit forests of the alps.

In the spring, birds have to work hard to feed their hungry offspring and keep them safe in beautiful, yet harsh environments.

Life in the alpine pastures of Tyrol has its own pace in tune with natural cycles. We visit an alpine farmer and his wife and learn about traditional dairy products and how they are made.

In this segment, we get to know the bearded vulture, a scavenging bird of prey that has resettled in the Hohe Tauern National Park. Now there are even stations in the park that address some of the misconceptions that almost led to this bird's extinction.

Our exploration of wildlife in the Tyrolean Alps continues as we visit cuddly marmots and one of their most fearsome predators: the golden eagle.

In a rare close-up, we see the mother eagle working hard to keep its offspring fed. Then we get a look at the Innergschlöß, an 800-year-old Alpine settlement.

Because they raise so many questions, celestial bodies have always fascinated humankind. Various probes — including Rosetta and her “little brother” Philae — have been sent into space to gather more information. This video presents the probes as courageous and curious figures in a whimsical fairy tale.
