New Species Discovered in the Ultra Deep
An exploration to one of the deepest places on earth has captured rare footage of what is believed to be three new species of the elusive Snailfish.
Estimate of Carbon in Indigenous Lands Rises Five-Fold
Land managed by indigenous people holds vastly more carbon than previously thought, according to a report that calls for an urgent strengthening of their land rights to avoid its release into the atmosphere.
Golden Sandwich Could Make the World More Sustainable
Scientists have developed a photoelectrode that can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods.
Coastal Erosion in the Arctic Intensifies Global Warming
The loss of arctic permafrost deposits by coastal erosion could amplify climate warming via the greenhouse effect. A study using sediment samples from the Sea of Okhotsk on the eastern coast of Russia led by AWI researchers revealed that the loss of Arctic permafrost at the end of the last glacial period led to repeated sudden increases in the carbon dioxide concentration in the atmosphere.
Global Warming Pushing Alpine Species Higher and Higher
For every one-degree-Celsius increase in temperature, mountaintop species shift upslope 100 metres, shrinking their inhabited area and resulting in dramatic population declines, new research by University of British Columbia zoologists has found.
