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.

2. Cross-section of four cable bacteria each with a circle of 15 wires just below the cell surface. (Credit: Karen E. Thomsen)
3. A small cavity in the seabed reveals a number of cable bacteria that conduct electric currents between the red surface and the deep, black, anaerobic sediment layers of the seabed. (Credit: Nils Risgaard-Petersen)
4. In a teaspoonful of mud, there may be one kilometre of living electric cables and bundles of them can be pulled up with the finger (Credit: Nils Risgaard-Petersen)
5. Cable bacteria in sediment. The wires become apparent on the bacterial outer surface as distinct ribs running across the cable bacteria cells. (Credit: Jie Song and Nils Risgaard-Petersen)

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.

Hans Røy on national radio

"Videnskabens Verden" focuses on Hans Røy's new findings. Listen to the program here.

The Japanese ship Chikyu is the world’s largest research drilling vessel. From 26 July to 27 September 2012 researchers are sampling from the ship off the Shimokita Peninsula in the northwestern Pacific.

Life in absolute slow motion

New research shows there is still life in clay that is 86 million years old, and the explanation is extremely low metabolism. The results challenge our conception of the limits for life.

Microbiologists can now measure extremely slow life

Microbiologists at Aarhus University have developed a new method for measuring slow life deep down in the seabed. The results can provide knowledge about the global carbon cycle and its long-term impact on the climate.

Bo Barker Jørgensen and Lars Peter Nielsen receive two ERC Advanced Grants

The life of microorganisms in the muddy world on the sea bed is hidden to the naked eye. There is nevertheless plenty of it. The European Research Council has just allocated two giant research grants to two professors from the Department of Bioscience, Aarhus University, who will investigate the microbiology of the sea bed, each in their own way.
