Global ocean sampling expedition

15.03.2007
Can we ever know the true measure of microbial diversity in the sea or of proteins in nature?

In three new metagenomic studies published online in the open-access journal PLoS Biology, Craig Venter and his team take advantage of the vast amount of microbial sequence data collected during their Sorcerer II Global Ocean Sampling (GOS) expedition to reveal an unprecedented level of genetic and protein diversity in marine microbes.

Venter's team combined the expedition's latest bounty, 6.5 million sequencing "reads," with data previously collected during a pilot study in the Sargasso Sea. The result is a geographically diverse environmental genomic dataset of 6.3 billion base pairs—twice the size of the human genome.

The first paper and accompanying poster by Douglas B. Rusch and colleagues describe the immense amount of microbial diversity in the seas, and discuss how—or if—that diversity is structured and what might be shaping that structure. The second paper by Shibu Yooseph and colleagues studies the 6.12 million proteins identified in the GOS sequences to see if we're close to discovering all the proteins in nature. In the third study, Natarajan Kannan, Susan S. Taylor, Gerard Manning, and colleagues present their classification of 45,000 kinases (including 16,000 from the GOS dataset) into 20 distinct families, revealing their structural and functional diversity and an unexpected role for kinases in prokaryotic signaling.

This collection also includes an accessible and nontechnical summary of the broad significance of this research by Liza Gross. Some unexpected intellectual property challenges have arisen from this project, and these are explored in a feature by Henry Nicholls. A "challenge series" essay by Jonathan Eisen provides insight into the issues surrounding the field of metagenomics today.

To host all the additional metadata that surround metagenomic studies, a new database, CAMERA, has been established, funded by the Gordon and Betty Moore Foundation. The GOS data are publicly available and ready for mining in CAMERA. You can read about the capabilities of CAMERA in a Community Page article by Rekha Seshadri and colleagues.

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...
