Permafrost alone holds back Arctic rivers—and a lot of carbon
New research from Dartmouth College provides the first evidence that the Arctic's frozen soil is the dominant force shaping Earth's northernmost rivers. Permafrost, the thick layer of soil that stays frozen for two or more years at a time, is the rea.....»»
Rare woolly rhino mummies emerge from the permafrost
The new finds confirm the existence of a feature seen in cave art. Enlarge / Portion of a reproduction of cave paintings in France, showing rhinos (among other species). (credit: JEFF PACHOUD) For most people, an extinct.....»»
Bridging large riverine ecosystems for inter-basin exchanges
Many of the world's large rivers have been modified to support food security, hydropower production, navigation and trade. While these developments are necessary to support a growing human population, they also pose substantial risks to the structure.....»»
New algorithm rights wrongs of precipitation-type classification over Tibetan Plateau
Like many natural phenomena, precipitation can be both a blessing and a scourge to human life. On the one hand, it supplies our rivers and fields with water; on the other hand, it can cause floods, landslides, and other natural disasters. Either way,.....»»
Scientists discover how TGF-Beta sends its message even while tethered to the cell membrane
For years, scientists have thought that TGF-Beta, a signaling protein that holds sway over an astonishing array of cellular processes from embryonic development to cancer, could only do its work once it escaped a lasso-like "straitjacket.".....»»
Road networks stretch into Congo Basin forests: Satellites and AI help to monitor
The Congo Basin rainforest is the second-largest tropical forest in the world, storing large volumes of carbon and hosting high levels of biodiversity. While these forests have historically stayed mostly intact, road development has recently become a.....»»
Mice made transparent with a dye used in Doritos
Matching refractive indexes lets some wavelengths pass cleanly through the skin. Enlarge / Zihao Ou, who helped develop this solution, holds a tube of it. One key challenge in medical imaging is to look past skin and ot.....»»
Researchers use training model to map planted and natural forests via satellite image
While planting trees may seem like an easy win to combat climate change, planted forests often encroach on natural forests, wetlands, and grasslands. This can reduce biodiversity, disturb the natural environment, and disrupt carbon and water cycling......»»
Genomics reveals sled dogs" Siberian lineage
New research co-led by Cornell University examines thousands of years of Arctic sled dog ancestry and reveals when and how Siberian and Alaskan sled dogs' DNA mixed......»»
The skyscraper-sized tsunami that vibrated through the entire planet and no one saw
Earthquake scientists detected an unusual signal on monitoring stations used to detect seismic activity during September 2023. We saw it on sensors everywhere, from the Arctic to Antarctica......»»
Exploring ternary metal sulfides as electrocatalysts for carbon dioxide reduction reactions
One of the most promising avenues for actively reducing CO2 levels in the atmosphere is recycling it into valuable chemicals via electrocatalytic CO2 reduction reactions. With a suitable electrocatalyst, this can be achieved under mild conditions and.....»»
Trees in tropical logged forests release carbon at greater rate despite faster growth, study finds
Tree stems in tropical forests recovering from logging produce carbon dioxide at a greater rate than those in unlogged forests, according to a new study from the University of Leicester......»»
Climate change is accelerating extreme melting in Greenland with global impacts, says study
Climate change is accelerating the melting of ice in Greenland at an alarming rate, with serious implications not only for the Arctic, but also for the global climate, including Europe. According to a study led by researchers at the University of Bar.....»»
New findings on the extent of golden jackal expansion
The golden jackal (Canis aureus) has rapidly expanded its range across Europe by thousands of kilometers. It has recently moved into new environments, reaching as far as north of the Arctic Circle in Finland and Norway, and south to the Iberian Penin.....»»
Rapid loss of Antarctic ice after 2100 likely under current emissions, climate scientists find
A Dartmouth-led study by more than 50 climate scientists worldwide provides the first clear projection of how carbon emissions may drive the loss of Antarctica's ice sheet over the next 300 years......»»
Microbe dietary preferences found to influence effectiveness of carbon sequestration in deep ocean
The movement of carbon dioxide (CO2) from the surface of the ocean, where it is in active contact with the atmosphere, to the deep ocean, where it can be sequestered away for decades, centuries, or longer, depends on a number of seemingly small proce.....»»
Development strategies for using carbon-based catalysts in CO₂ conversion
One of the primary drivers of climate change, CO2 emissions, has reached over 35 million tons worldwide. With global annual temperatures still rising, reducing CO2 emissions has become a necessity. To turn this necessity into an opportunity, research.....»»
How the west is foiling Russia"s attempts to use the Arctic in the Ukraine war
Things are not exactly going to plan for Moscow in the Arctic—an area that is a strategic military region for Russia and has significant economic potential that could help Russia in propping up its war economy. Yet, a combination of Ukrainian milit.....»»
Personal carbon footprint of the rich is vastly underestimated by rich and poor alike, study finds
The personal carbon footprint of the richest people in society is grossly underestimated, both by the rich themselves and by those on middle and lower incomes, no matter which country they come from. At the same time, both the rich and the poor drast.....»»
Ozone pollution reduces yearly tropical forest growth by 5.1%, study finds
Ozone gas is reducing the growth of tropical forests—leaving an estimated 290 million tonnes of carbon uncaptured each year, new research shows......»»
A CGE model for provincial analysis of China"s carbon neutrality target
