A recently opened pulp mill in Chile has devastated one of South America’s most biologically outstanding wetlands, decimating its famed population of black-necked swans, along with most other bird life, a WWF-led team of investigators said Monday.
"What was probably the largest population of black necked swans in South America has been wiped out in less than a year. It is an environmental catastrophe," said Clifton Curtis, director of World Wildlife Fund’s Global Toxic Program. "Before the pulp mill, there were more than 5,000 black necked swans in the Carlos Anwandter Nature Sanctuary. When we visited the core of the sanctuary in August, we could find only four."
The Carlos Anwandter Nature Sanctuary covers more than 12,000 acres of wetlands along the Cruces river in the southernmost Chilean province of Valdivia. An officially designated "wetland of international importance" under the Ramsar convention, it was home to more than 100 species of rare, vulnerable or, in at least two cases, endangered species of birds--the Coscoroba swan and the white-faced Ibis. It was also the largest nesting area in South America for the black necked swan, the region’s iconic species and a major tourist attraction.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
