A team from the Institute of Forest Sciences at the University of Freiburg shows that the extraction of ground water for industry and households is increasingly damaging floodplain forests in Europe given the increasing intensity and length of drought periods in the summer. The scientists have published their results in the journal Frontiers in Forests and […]
New University of Montana research suggests climate change makes it increasingly difficult for tree seedlings to regenerate following wildfires in low-elevation forests, which could contribute to abrupt forest loss. The study, "Wildfires and Climate Change Push Low-elevation Forests Across a Critical Climate Threshold for Tree Regeneration," was published March 11 in the Proceedings of the National […]
Trees growing near the South Pole, sea levels 20 metres higher than now, and global temperatures 3C-4C warmer. That is the world scientists are uncovering as they look back in time to when the planet last had as much carbon dioxide in the atmosphere as it does today. Using sedimentary records and plant fossils, researchers […]
Media outlets and politicians routinely refer to the “flood” of Central American migrants, the “wave” of asylum seekers, the “deluge” of children, despite the fact that unauthorized migration across the US borders is at record lows in recent years. Comparing human beings to natural disasters is both lazy and dehumanizing, but perhaps this tendency to […]
Five years ago, researchers spent three hours packed aboard a steamy Gulfstream-1 research aircraft as it zig-zagged between pristine air over the Amazon rainforest and polluted air nearby. It was like a trip back (and forth) through time, as scientists weaved between the two vastly different settings, snagging air samples characteristic of today's industrial environment […]
Canada is warming on average at a rate twice as fast as the rest of the world, a new scientific report indicates. The federal government climate report also warns that changes are already evident in many parts of the country and are projected to intensify. Canada's Arctic has seen the deepest impact and will continue to warm […]
Scramble across exposed rocks in the middle of Antarctica and it's possible to find the mummified twigs of shrubs that grew on the continent some three to five million years ago. This plant material isn't much to look at, but scientists say it should serve as a warning to the world about where climate change […]
A killer skin fungus that caused the death of frogs has now been found out to be responsible for damaging biodiversity around the world. Dubbed as the fungus that caused an amphibian apocalypse, this pathogen has affected more living beings than any other disease ever recorded. It has displaced cats and rodents and is the […]
Health officials are alarmed by growing waves of a paralyzing illness in children. So far the disease has only affected a few hundred children in the United States, but the exact cause and best treatment for this disease remain unknown. Known as acute flaccid myelitis, or AFM, this rare illness can sometimes cause respiratory failure […]
Biophysicists have used an automated method to model a living system — the dynamics of a worm perceiving and escaping pain. The Proceedings of the National Academy of Sciences (PNAS)published the results, which worked with data from experiments on the C. elegans roundworm. "Our method is one of the first to use machine-learning tools on experimental data to […]
