French and Australian scientists resume measurements of Antarctic waters south of Australia this week to assess their capacity as a massive oceanic sponge to absorb greenhouse gases and store them away for hundreds or perhaps thousands of years.
France and Australia have a joint research program taking measurements from the Antarctic supply ship LAstrolabe during its voyages between Hobart and the French base at Dumont DUrville. LAstrolabe, equipped with a full sampling laboratory, sails from Hobart on Tuesday 19 October in the first voyage of the season. Professor Alain Poisson from the University of Paris and Dr Bronte Tilbrook from CSIRO oversee the research.
Later in the year the ice breaker Aurora Australis will head south from Fremantle to make a similar set of measurements and to extend the work to the west of the Astrolabe track. "The Southern Ocean is so important for controlling the concentration of carbon dioxide in the atmosphere," Dr Tilbrook says. "The Astrolabe work is helping us obtain a much clearer picture of the interaction between ecosystems and mixing that drives the carbon dioxide exchange between the ocean and atmosphere."

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...
