Radio interview on life in the basaltic crust

Mark Lever presents new research results in the CBC morning news.

The core sample has just been brought up from the bottom of the Bay of Aarhus and is being cut up. The researchers find archaea in the samples, which – to their great surprise – turn out to live on protein degradation. Image: Bo Barker Jørgensen.

Four cells turn seabed microbiology upside down

With DNA from just four cells, Danish researchers reveal how some of the world’s most abundant organisms play a key role in carbon cycling in the seabed.

Energy from the interior of the Earth supports life in a global ecosystem

The Earth’s oceanic crust covers an enormous expanse, and is mostly buried beneath a thick layer of mud that cuts it off from the surface world. Scientists now document life deep within the oceanic crust that appears to be sustained by energy released from chemical reactions of rocks with water.

Cable bacteria are a hit

Nature’s electrical bacteria were in the running when the Danish Research Result of the Year 2012 was selected by readers of Videnskab.dk.

Articles about the gorilla genome and electric bacteria are among the favourites to win the prize as the Danish Research Result of the Year 2012.

Seek a firm footing in the depths

The opening of the new Centre for Geomicrobiology was a good occasion to make flattering remarks about a pioneering research field that has already succeeded in challenging and revolutionising the common perception of what life is all about.

New basic research centre will study secrets of life in the sea bed

A few decades ago, a large part of life on Earth was unknown to anyone – i.e. life deep down in the sea bed. The old mysteries of the sea bed constitute a young field of research that will now be dealt with by the new centre at Aarhus University.

Mud research on TV

Via two “IQ programs” the residents in eastern Jutland will get an idea of the ongoing research at the Department of Bioscience. Watch the next program this coming Wednesday or watch them on the Internet.

Living cables explain enigmatic electric currents

The enigma of electric currents in the seabed is solved. Scientists from Aarhus University have sensationally discovered bacteria that function as living electrical cables. Each of the centimetre-long 'cable bacteria' contains a bundle of insulated wires leading an electric current from one end to the other.

New world record in scientific deep-sea drilling

The Japanese drilling vessel Chikyu has collected samples 2,200 m below the seafloor. Mark Lever from the Center for Geomicrobiology is among the scientific party.
