But a new study suggests that for some Western U.S. forests, it’s quite the opposite. In the journal Global Change Biology, researchers have published one of the first large-scale studies of U.S. forest land exploring the link between forest resilience and mortality. The study is based on more than three decades of satellite image data …

Many years later, scientists poring over satellite data could finally put numbers behind sailors’ intuition: The Southern Hemisphere is indeed stormier than the Northern, by about 24%, in fact. But no one knew why. A new study led by University of Chicago climate scientist Tiffany Shaw lays out the first concrete explanation for this phenomenon. …

Lithium-ion batteries — used in products from appliances to cell phones, as well as in most electric vehicles — are composed of a cathode and an anode with an electrolyte in between. Ions move from anode to cathode through the electrolyte in a reaction that converts chemical energy to electrical energy. The drive toward decarbonization …

However, synthesis of 3D COFs from pre-designed building units leading to net-like “reticular” arrangement of constituent parts or “network topologies” remains challenging. This is due to the shortage of 3D building units and inadequate reversibility of the linkages between the building units. Recently, Professor Yuichi Negishi from the Department of Applied Chemistry, Faculty of Science, …

Until now, most studies calculated the Arctic melt and freeze onsets using remote sensing observations from the surface, but rarely investigated the freeze-thaw process at ice bottom. In a new study published today in the European Geosciences Union journal The Cryosphere, an international team of scientists synthesized multisource data from 2001 to 2018 to explore …
Now, a research group has laid the path for achieving higher open-circuit voltage in tin sulfide (SnS) solar cells, thus realizing their latent potential as a thin-film solar material. Thin-film solar cells, which comprise compound semiconductors with strong light absorption, require less raw materials, making them lighter and cheaper to produce. SnS is one such …
Because microplastics can accumulate other environmental contaminants on their surfaces, such as heavy metals or organic molecules, they could pose even more of a problem for wildlife, plants or humans than originally thought. Previous research has shown that heavy metals can easily attach to microplastics, and that this combination could potentially harm aquatic life. But …

A new MIT study finds that the health benefits associated with wind power could more than quadruple if operators prioritized turning down output from the most polluting fossil-fuel-based power plants when energy from wind is available. In the study, published in Science Advances, researchers analyzed the hourly activity of wind turbines, as well as the …

Led by researchers from Institute of Psychiatry, Psychology & Neuroscience (IoPPN), King’s College London, this is the largest study worldwide to examine whether air pollution exposure is linked with the occurrence of multiple long-term health conditions. Multimorbidity is defined as having two or more physical or mental health conditions and affects 27 per cent of …
Hydrogen is seen as an important part of the decarbonisation of the heavy transport sector and around the world hydrogen-powered trains, trucks and airplanes are being developed and deployed. Even in heavy industry, hydrogen is regarded as very important, for example for the production of fossil-free steel. The risks of storing or using hydrogen are …
