Scientists discover new life forms in the Arctic Ocean

15.01.2007
An international team of scientists including Université Laval biologist Connie Lovejoy has discovered new life forms in the Arctic Ocean. The team's findings are reported in the January 12 edition of the journal Science.

The researchers have discovered a new group of microscopic organisms, which they have baptized "picobiliphytes": pico because of their extremely small size, measured in millionths of a meter, bili because they contain biliproteins, highly fluorescent substances that transform light into biomass, and phyte meaning they are plants.

The discovery came from carefully analyzing DNA sequences belonging to vast communities of micro-organisms living in the ocean. "There was one group of sequences that just didn't line up with any of the known groups," explains Dr. Lovejoy. "In fact, the divergence of this group from known organisms is as great as the difference between land plants and animals," adds the scientist.

Over this last year the team has been scouring data bases, verifying their results and applying new techniques to their samples. They can now confirm that these new life forms are abundantly distributed throughout northern seas. They have yet to be brought into culture, but can be seen using advanced microscopy techniques.

"It's a very exciting discovery," comments Dr. Lovejoy. "The ocean covers 70% of planet earth and we are only now coming to appreciate its rich and complex biodiversity."

The other members of the team responsible for this discovery are Fabrice Not, Khadidja Romari, and Daniel Vaulot from Université Pierre et Marie Curie (France); Klaus Valentin, Kerstin Töbe, and Linda Medlin from the Alfred Wegener Institute for Polar and Marine Research (Germany); and Ramon Massana from Institut de Ciències del Mar (Spain).

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
