Acidification threatens important oxygen suppliers

The carbon dioxide emitted by mankind not only drives global warming, but also lowers the pH values in the sea. This harms even diatoms.

The Siberian tundra could almost completely disappear

Due to global warming, the larch forests in northeastern Russia are spreading further and further north. As a result, the Siberian tundra could shrink to six percent of its surface area by the middle of the millennium. Even with rigorous climate protection measures, things look bleak, as one model shows.

Sponge bleaching worries scientists

A strong heat wave in the ocean around the New Zealand South Island has consequences: For the first time, sponge reels bleach over a large area.

The notorious Omega

Europe is threatened by an Omega weather situation. It is particularly stable and therefore feared. If it does not end, we could have a similarly hot summer as in 2018.

Heat wave triggers new mass bleaching

After a months-long heat wave, much of the Great Barrier Reef is affected by bleach. It is the fourth mass bleaching since 2016. But with falling temperatures, the corals could recover.

Protecting biodiversity with a knife and fork

What we eat affects not only our health, but also in the countless species. New studies show how great the influence of our eating habits is and what potential is changing awareness.

Almost 30 percent more droughts than 20 years ago

So far, Dürren has mainly appeared on the African continent. But Europe is also becoming increasingly drier. A large part of the world's population could be affected by 2050.

The right equation will help protect squirrels

Squirrels are great animals. There is hardly anything more relaxed than watching them around on a tree or nibbling a nut. But if you want to get biodiversity, it is worth taking a look at mathematics. Because the squirrelpox is rampant among them!

The perfect domino effect

When one of a series of dominoes falls over, a chain reaction often occurs. How fast it runs and whether it works without interruption depends on several parameters: the distance of the stones, the friction between them and the interaction with the substrate.

"The idea of a double sexuality is refuted"

Do women like masculine types more on their fertile days? A myth, says psychologist Lars Penke from the University of Göttingen in an interview. »The cycle does something to women psychologically, but not as expected.«

A touch of wormhole

Theoretical models try to unite the two great physical natural theories. They link structures in space -time with quantum mechanically entangled particles. Such a connection was simulated with a quantum computer, but massively simplified.

The universe, the Earth and all the rest

The geoscientist Christian Klepp traces the history of the earth in a book written with a lot of love for his subject. The content is not new, but the spark of enthusiasm for the knowledge of textbooks jumps over thanks to the successful narrative structure and excellent nature photography.
