Climate change and species extinction, two phrases that seem to be on everyone’s mind. But opinions diverge and even if the majority of us can no longer deny climate change – as the signing of the Kyoto agreement by most countries shows – its real dimension and impact on species extinction is still very controversial. But now scientists from Oxford University’s Biodiversity Research Group and colleagues decided to test our capacity to see the future by…going back to the past. And the conclusion is that the most commonly used models to predict species extinction are basically not that good. But not all is bad news.
Where are we going to be in 100 years’ time? The scientific results that reach the public vary so much that we can no longer know what to believe and many times it’s simply our political choices that define our ecological opinion. We are not challenging scientists’ integrity, but how accurate are their forecasting models? The problem is that we cannot go to the future to test their predictions.
But now Miguel B. Araújo, Robert J. Whittaker, Richard J. Ladle and Markus Erhard from the Oxford University’s Biodiversity Research Group, the London’s Natural History Museum Biodiversity Research Group and the Institute for Meteorology and Climate Research in Germany, in a paper just published online in the journal of Global Ecology and Biogeography might have found a solution by approaching the problem in a very different way.

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...
