World’s fastest fish continues to impress

The sailfish is not only the world’s fastest swimmer. A new video reveals that its movements during hunting are the quickest ever seen in a marine animal.

Sperm whale language under scrutiny

A new project aims to decode the sperm whale’s communication system using the latest animal-borne acoustic technology.

Copenhagen invaded by research fleet

As part of this summer’s science festival ’Science in the City’, a fleet of research ships will be docking in Copenhagen. The public is invited on board to learn about the ins and outs of marine research.

Map outlines global hotpots of bycatch intensity

Fishery bycatch poses a great threat to various endangered species, and to ecosystems in general. Scientists have now mapped out the problem.

Metabolism works differently than we thought

Kleiber’s law of metabolism, which states that the metabolic rate of an animal scales to the 3/4 power of the mass, has a flaw in it, argues Danish scientist.

Animal origin theory challenged: Early animals needed almost no oxygen

The first animals on Earth could get by with much less oxygen than previously thought, new study reveals.

Even tiny oil spills may break Arctic food chain

Drilling for oil in the Arctic may have catastrophic consequences, new study suggests.

Huge meltwater reservoir found under Greenland ice

A reservoir of meltwater the size of Ireland has been found within Greenland’s ice sheet. The reservoir may increase the melting of the inland ice in the future and provides fundamental new insights into the dynamics of the Greenland ice cap.

How algae slime impacts the climate

Algae in the sea ice around the Arctic and the Antarctic convert CO2 into micro-gels. This makes it possible to see whether this cold slime actually counteracts climate change.

Climate change fills polar bears with toxins

The melting ice around Greenland has changed the polar bear’s diet. This means that they are being filled with large quantities of environmental poisons, and that forms a threat to the polar bear’s existence.
