Political colour is half genetic

New study provides definitive evidence that heritability plays a significant role in the formation of political ideology, regardless of how ideology is measured, the time period or population sampled.

Surviving ash trees help to address evolutionary riddle

A pathogenic fungus is killing thousands of European ash trees every year. Danish researchers are now trying to uncover the genetics behind the unknown defence mechanism in ash trees. Not only to save the ash trees, but also to address an evolutionary mystery in trees.

Ancient fish face bears signs of modern jaw

A smiling fish that lived in China 419 million years ago revolutionises our conception of the origin of humans and most other vertebrate animals.

Oxygenated Earth much older than we thought

The discovery of the world’s oldest soil suggests that Earth’s atmosphere contained oxygen as early as three billion years ago. That’s 700 million years earlier than previously thought.

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.

Cold no curb on appetite

Living in a low temperature environment does not affect bacteria’s appetite for hydrocarbons, according to recent research. This new knowledge could affect environmental risk assessment in the Arctic.

A targeted defence against harmful hemoglobin

Hemoglobin is both vital and life-threatening. A new project sets out to find out how the body deals with the problem of harmful hemoglobin, and how this knowledge can be used to save lives.

Why insects always hide in the dark

It is no coincidence that insect larvae always hide away in dark corners. Scientists have now discovered how the larvae know where it’s best to hide away.

Bison may boost Danish vegetation

A new study sets out to clarify what effect the reintroduction of bison will have on the Danish countryside. The bison may open up for a more diverse flora, says researcher.
