Remote ‘marine deserts’ and dense plankton blooms could provide scientists with clues for understanding climate change.
A research team will set sail from Southampton, Friday, 17th September 2004, for the start of an expedition to study the interaction between the atmosphere and plankton – tiny floating marine organisms. By monitoring these organisms and the influence of changing climate on their growth, they hope to discover whether they act as a source of carbon dioxide, or a ‘sink’ in which the carbon is contained.
Dr Andy Rees, Principal Scientist on the ship said ‘The ship will pass close to the coast of Africa, where we hope to find large numbers of plankton, called blooms. These blooms may be due to nutrient rich water rising to the surface or to dust, laden with nutrients, blown across from the Sahara providing food for the plankton. These areas act as natural chimneys of gases which contribute to global warming. We will have the opportunity to sample some hugely contrasting environments because of the meeting of waters from the northern and southern hemispheres. We will compare this area with barren desert regions of the Atlantic where there are very small numbers of plankton.’

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
