Viruses, oxygen and our green oceans

03.04.2008
Some of the oxygen we breathe today is being produced because of viruses infecting micro-organisms in the world’s oceans, scientists heard today (Wednesday 2 April 2008) at the Society for General Microbiology’s 162nd meeting being held this week at the Edinburgh International Conference Centre.

About half the world’s oxygen is being produced by tiny photosynthesising creatures called phytoplankton in the major oceans. These organisms are also responsible for removing carbon dioxide from our atmosphere and locking it away in their bodies, which sink to the bottom of the ocean when they die, removing it forever and limiting global warming.

“In major parts of the oceans, the micro-organisms responsible for providing oxygen and locking away carbon dioxide are actually single celled bacteria called cyanobacteria,” says Professor Nicholas Mann of the University of Warwick. “These organisms, which are so important for making our planet inhabitable, are attacked and infected by a range of different types of viruses.”

The researchers have identified the genetic codes of these viruses using molecular techniques and discovered that some of them are responsible for providing the genetic material that codes for key components of photosynthesis machinery.

“It is beginning to become to clear to us that at least a proportion of the oxygen we breathe is a by-product of the bacteria suffering from a virus infection,” says Professor Mann. “Instead of being viewed solely as evolutionary bad guys, causing diseases, viruses appear to be of central importance in the planetary process. In fact they may be essential to our survival.”

Viruses may also help to spread useful genes for photosynthesis from one strain of bacteria to another.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
