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: With artificial intelligence to a better wood product

Empa scientist Mark Schubert and his team are using the many opportunities offered by machine learning for wood technology applications. Together with Swiss Wood Solutions, Schubert develops a digital wood-selection- and processing strategy that uses artificial intelligence.

Wood is a natural material that is lightweight and sustainable, with excellent physical properties, which make it an excellent choice for constructing a wide...

Im Focus: Atoms don't like jumping rope

Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.

By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...

Im Focus: Images from NJIT's big bear solar observatory peel away layers of a stellar mystery

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.

With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Im Focus: New Pitt research finds carbon nanotubes show a love/hate relationship with water

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.

New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
