Scientists investigate marine photosynthesis

20.03.2008
Scientists from the Department of Biological Sciences at the University of Essex have been awarded £400,000 to study the effects of phosphorous and iron limitation on photosynthetic algae crucial to combating global warming.

The project, funded by the Natural Environment Research Council, will involve growing two different species of cyanobacteria – photosynthetic algae that are able to fix nitrogen from the atmosphere – under different conditions. Dr Tracy Lawson and Professors Richard Geider and David Nedwell will study how reductions in phosphorous and iron affect the ability of the cyanobacteria to fix nitrogen and carry out photosynthesis.

Dr Lawson, who is leading the project, explained: ‘Photosynthesis by marine algae is important as the ocean can act as a sink for carbon dioxide from the atmosphere. So, by increasing photosynthesis in the ocean, we may be able to reduce carbon dioxide in the atmosphere that is produced by man and counteract global warming.’

The reduction of phosphorus and iron is expected to affect the photosynthetic structure and function in different ways: iron is required for certain parts of the photosynthetic electron transport chain while phosphorous is required for the production of energy and as the building blocks of nucleic acids and protein.

Because photosynthesis also requires light and carbon dioxide, the researchers will also alter the light environment and carbon dioxide concentration that the algae will be grown under. By growing the cultures in such controlled conditions the researchers will be able to closely mimic the natural environment. This will be the first time some of these cultures have been grown in this way.

Dr Lawson added: ‘This work will give us information that is vital for use in mechanistic models that will predict marine responses to climatic change under different nutrient, light and carbon dioxide regimes.’

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
