Oilfields have reduced their methane emissions

Capturing methane-rich natural gas from oilfields has helped ensure that emissions of methane have been far lower than expected, a new study shows.

An entire army sacrificed in a bog

Archaeologists have found skeletal remains of an entire army in an ancient mass grave in Denmark. The bones confirm reports from written sources of shocking Teutonic massacres.

Hydrogen sulphide and lack of oxygen stifled early life

After the Triassic geological period gave way to the Jurassic, life was almost impossible on the seabed in coastal waters. The water here lacked oxygen but was rich in toxic hydrogen sulphide.

Research gives clean drinking water for millions of Vietnamese

Geological studies carried out by Danish researchers are giving hope to the millions of people in Southeast Asia who drink groundwater contaminated by arsenic – a highly poisonous substance.

Aerial photos from Greenland topple climate models

Greenland’s ice sheet is not behaving as scientists have expected, and the climate models must be revised, new research suggests.

How to build the perfect sandcastle

Scientists have come up with a formula that makes it possible to build spectacular sandcastles.

Study casts doubt on popular mass extinction theory

A new study casts doubt on a popular theory about the mass extinction that occurred in the transition between two geological periods, the Triassic and the Jurassic. The findings give us a better understanding of today’s climate changes, scientists claim.

Greenland is rising out of the sea

Melting ice is currently causing Greenland to rise by 3 cm a year. This rate is accelerating, and if the entire ice sheet is to disappear, the island would rise about one kilometre, new GPS readings reveal.

Remains of gigantic meteorite crater found in Greenland

A Danish geologist has discovered remains of what appears to be the world’s largest and oldest meteor impact crater in Greenland.

Unearthing the cause of mass extinction

The cause for mass extinction can be unearthed by looking at big volcano-like offshore structures in Norway and South-Africa.
