Down in the slumps: Tracing erosion cycles in arctic permafrost
In the Arctic, landslide-like features known as mega retrogressive thaw slumps are threatening infrastructure, altering regional biogeochemistry, and emitting carbon......»»
Tiny crustaceans discovered preying on live jellyfish during harsh Arctic night
In the dark and cold of the months-long polar night, food resources are limited. Some groups of marine organisms in the polar regions overcome this challenge by going into a metabolic resting state in winter, surviving on reserves accumulated during.....»»
Researchers identify a decline in microbial genetic richness in the western Arctic Ocean
The Arctic region is experiencing climate change at a much faster rate than the rest of the world. Melting ice sheets, runoff from thawing permafrost, and other factors are rapidly changing the composition of the Arctic Ocean's water. And that change.....»»
Countries Are Building Giant ‘Sand Motors’ to Protect Their Coasts From Erosion
As sea levels rise, engineers are using massive Dutch-inspired sand sculptures to protect shorefront settlements......»»
Watch Volkswagen’s Super Bowl ad telling its 75 years of American history
The ad begins with the Beetle’s 1949 arrival, tracing how VW entered U.S. pop culture, from its Hippie Microbus to the classic Passat Darth Vader Super Bowl ad. .....»»
Cold-resistant bacteria found in the Arctic can degrade crude oil
The Arctic region is being actively developed by humans, but it negatively affects the environment. The fact is that Arctic soils, which contain little organic matter, are susceptible to the toxic effects of hydrocarbons that get there as a result of.....»»
A new map tool for monitoring pan-Arctic trends of permafrost landscape change
Permafrost (from "permanent" and "frost") is ground that continuously remains at or below 0° C for at least two consecutive years. Around 15% of the land surface in the Northern Hemisphere is underlain by permafrost, which often contains and preserv.....»»
New UN weather agency chief says rate of global warming is speeding up
The new chief of the World Meteorological Organization said it looks to her that the rate of human-caused climate change is accelerating and that warming has triggered more Arctic cold outbreaks in North America and Europe, weighing in on two issues.....»»
Innovative detection system allows researchers to differentiate oak wilt and drought
Oak forests play a vital role in our ecosystem, providing climate regulation and erosion control across North America. However, these forests face compounding threats from drought and oak wilt, and it can be challenging to tell these two issues apart.....»»
Frequent marine heat waves in the Arctic Ocean will be the norm, says new study
Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions, according to a study just released by Dr. Armineh Barkhordarian from Universität Hamburg's Cluste.....»»
Study finds high nitrogen fertilizer input enhances the microbial network complexity in paddy soil
In paddy field, flood-and-drain cycles produce variations in reduced and oxidized environments, which are appropriate habitats for a wide variety of microorganisms. Nitrogen (N) fertilization drives the structure and function of soil microbial commun.....»»
Alex Honnold on life after Free Solo and new docuseries Arctic Ascent
In a conversation with Digital Trends, famed climber Alex Honnold discusses finding purpose after El Cap and filming his new Disney+ docuseries, Arctic Ascent......»»
Hungry sea otters are helping save California"s marshlands from erosion
The return of sea otters and their voracious appetites has helped rescue a section of California marshland, a new study shows......»»
Sedimentary records of contaminant inputs in Frobisher Bay provide record of changes in contaminant levels over decades
Although contaminant levels in Arctic environments are often lower than those in temperate locations close to cities and industrial areas, contaminant studies in the Arctic remain important due to the potential for bioaccumulation and biomagnificatio.....»»
Tracing the evolution of sign languages using computer modeling
An international team of linguistics experts has traced the origins of the most common modern sign languages using a computer model to compare them against one another. The research is published in the journal Science......»»
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.....»»
Improving Arctic greenhouse gas sink and source estimates with field measurements, remote sensing
A new study investigates the sinks and sources of key greenhouse gases of carbon dioxide, methane, and nitrous oxide in the Arctic landscape with a spatial resolution of only a few square meters. Vegetation and soil conditions explain the differences.....»»
VW founds AI lab, in talks with potential partners
VW aims to generate early-stage prototypes in areas like AI-optimized charging cycles, predictive maintenance services and voice recognition......»»
Study finds greater financial stability for graduates with two majors
Here's one good reason for college students to consider a double major: It could soften the blow to their incomes from future economic slumps......»»
Lopsided galaxies shed light on the speed of dark matter
In new research published in Astronomy & Astrophysics, researchers have figured out how to precisely calculate the forces that affect galaxies in tidal cycles. The next stage is to find galaxies sufficiently lopsided in the universe to study the velo.....»»
