Three critical factors in the end-Permian mass extinction

Two-hundred fifty-two million years ago, volcanic eruptions led to massive climate changes. Around the globe, roughly 75 percent of all land-based organisms and roughly 90 percent of all marine organisms died out as a result. ...

How horses can save the permafrost

Permafrost soils in the Arctic are thawing. As they do, large, additional quantities of greenhouse gases could be released, accelerating climate change. In Russia, experiments are now being conducted in which herds of horses, ...

Ultracold atoms and ultrafast lasers

Two separate research fields have been united in Hamburg for the very first time. Ultrashort laser pulses enable us to observe and manipulate matter on very short time scales, whereas ultracold atoms permit experiments with ...

A direct view on spin-waves

Spin-waves are promising candidates for future information processing schemes as there is almost no frictional heating in magnetic transport. Information encoding, however, is only possible in spin-wave packets. A group of ...

How climate change is destroying Arctic coasts

Global warming is causing permafrost in the Arctic to thaw and sea ice to melt. As a result, coasts are less protected and are being eroded, while carbon stored in the soil and carbon dioxide are being released into the ocean ...

Using strategy to preserve biodiversity while saving space

In South and Central America, an especially high number of biodiverse areas are in jeopardy. Tropical rainforests are being cleared so that the land can be used for livestock grazing and planting soybeans. To compensate for ...
