A moss capable of removing arsenic from contaminated water has been discovered by researchers from Stockholm University. And it happens quickly – in just one hour, the arsenic level is so low that the water is no longer harmful for people to drink. The study has been published in the journal Environmental Pollution.

REDD+ (Reducing emissions from deforestation and forest degradation) is an UN-led programme aiming to increase carbon sequestration in tropical forests. REDD+ is included among technologies for negative emissions, which stand for a large share of the emission reductions in the climate models internationally agreed on to keep global warming below 2°C. But increasing forest cover in developing counties can threaten other values, as shown in this new study. In southern Ethiopia the tree heather heathlands above the treeline are regularly burnt in order to improve livestock pasture, a practice that authorities within the REDD+ system now tries to stop in order to increase carbon storage. A new study from Stockholm University shows that the ancient pasture burning maintains biodiversity and habitats for alpine plant species not found anywhere else

Plants may have exerted greater influence on our terrestrial ecosystems than the megaherbivores that used to roam our landscapes, according to new research.

An unconventional mélange of algae, eucalyptus and bioenergy with carbon capture and storage (BECCS) appears to be a quirky ecological recipe. But, scientists from Cornell, Duke University, and the University of Hawaii at Hilo have an idea that could use that recipe to help power and provide food protein to large regions of the world – and simultaneously remove a lot of carbon dioxide from Earth’s atmosphere.

Heat and cold waves affect people with certain health conditions differently, highlighting the need for tailored public service risk communication.

Large wildfires cause increases in stream flow that can last for years or even decades, according to a new analysis of 30 years of data from across the continental United States.

People in crowded urban areas – especially poor areas – see fewer songbirds such as tits and finches, and more potential “nuisance” birds, such as pigeons, magpies and gulls, new research shows.

In the world of Costa’s hummingbirds, it’s not size that matters—it’s sound. During breeding season, male Costa’s perform a high-speed dive during which they “sing” to potential mates using their tail feathers.

As expected, Tropical Cyclone Keni followed a track similar to Tropical Cyclone Josie and passed to the southwest of Fiji's main island of Viti Levu on April 10, 2018 (UTC).

UBC researchers have perfected a process to efficiently separate fibreglass and resin – two of the most commonly discarded parts of a cellphone – bringing them closer to their goal of a zero-waste cellphone.
