Danish scientists have discovered a cell mechanism that can explain the development of some of types of cancer.

Professor: ‘Focus on the broader issues when you communicate’

How do you get science out of its ivory tower? A Q&A with world-famous evolutionary biologist Eske Willerslev.

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.

Computer model to detect prevalent diseases

New research aims to make it possible to assess people’s genetic risk for a variety of widespread diseases using a computer model.

Humans alone killed off the giant moa bird

New research reveals that the moa population were fit and healthy before humans started hunting the bird. In spite of this, it took less than 200 years before the gigantic bird had died out.

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.

Why do headless chickens run?

The brain does not control all body movements. Some movements are to a great extent controlled by neural networks in the spinal cord. This is why a chicken can run away after you chop its head off. A new study takes a closer look at this strange phenomenon.
