Scientists are still learning whats in a drop of ocean water, according to this weeks Nature Magazine. And the answers have implications for the whole planet, says co-author Craig Carlson, an oceanographer at the University of California, Santa Barbara. Carlson is an assistant professor in the Department of Ecology, Evolution and Marine Biology.
About ten thousand bacterioplankton of the type SAR 11 are found in every drop of seawater. And yet, as explained in the article, which gives the first accurate quantitative assessment of SAR 11, scientists are only beginning to understand what these organisms do.
The article is the result of a collaborative effort between Craig Carlson, and his lab, and Stephen Giovannoni of Oregon State University (OSU) and his lab, including first author Robert Morris. They are attempting to better understand the role of microbes in natural systems. The work was conducted under the Oceanic Microbial Observatory project, a joint effort between UCSB, OSU and the Bermuda Biological Station for Research that was initiated in 1999 by the National Science Foundation.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
