In time for the 22 May 2006, which is the International Day for Biological Diversity, GreenFacts has published a popularised version of the Millennium Assessment Report on Biodiversity. It is available at www.greenfacts.org/biodiversity/ in English, and soon also in French, Dutch and Spanish. The summary was produced in partnership with IUCN (the World Conservation Union), Countdown 2010 and UNEP World Conservation Monitoring Centre.
This year’s International Day for Biological Diversity marks the 16th anniversary of the adoption of the Convention on Biological Diversity. According to this Convention, Biodiversity – the number, variety, and variability of living organisms – is not just about plants, animals, microorganisms and their ecosystems, but also about humans and their needs such as food security, clean air and water, as well as a healthy environment.
The Millennium Ecosystem Assessment (MA) was launched by UN Secretary General Kofi Annan in 2001 to provide scientific information concerning the consequences of ecosystem change for human well-being and options for responding to those changes. It involved over 1300 scientists from 95 countries and produced a series of assessment reports.

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...
