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......»»
46,000-Year-Old Worm Possibly Revived from Siberian Permafrost
An international team of scientists says nematodes found in Siberian permafrost are 46,000 years old and survived using techniques similar to those of a modern lab favorite.....»»
Genome analysis of 46,000-year-old roundworm from Siberian permafrost reveals novel species
Some organisms, such as tardigrades, rotifers, and nematodes, can survive harsh conditions by entering a dormant state known as "cryptobiosis.".....»»
"Time-traveling" pathogens in melting permafrost pose likely risk to environment, say scientists
Ancient pathogens that escape from melting permafrost have real potential to damage microbial communities and might potentially threaten human health, according to a new study by Giovanni Strona of the European Commission Joint Research Center and co.....»»
Cross-seasonal connection found between Arctic sea ice and Eurasian summertime temperature
In recent decades, the Arctic region has been experiencing noticeable warming and substantial sea ice loss. While research has shed light on the influence of the Arctic on mid-latitude weather and climate during winter, its impact on summertime condi.....»»
There’s yet another hiccup with AMD ray tracing support
It appears that gamers who are eager to play Ratchet & Clank: Rift Apart on PC may have to play without ray tracing if they're using an AMD GPU......»»
Earlier and earlier high-Arctic spring replaced by "extreme year-to-year variation"
About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence reported in the journal Current Biology on.....»»
Research highlights importance of including Indigenous cultural perspectives in coastal restoration plans
Earthen and shell mounds built hundreds of years ago by Indigenous people in the Mississippi River Delta contribute to biodiversity and the area's resiliency to erosion today, research by a Florida State University archaeologist has found......»»
Greenland has greener history than previously thought
New analysis of samples collected from underneath Greenland's ice sheet reveal the Arctic island was much greener as recently as 416,000 years ago. The findings overturn previous views that Greenland's continental glacier, which covers about 80 perce.....»»
How sea-ice anomalies in the Barents–Kara Sea are modulated by the "warm Arctic–cold Eurasia" pattern
"Warm Arctic—cold Eurasia" is one of the most significant patterns of winter climate system changes in the mid-high latitudes of the Northern Hemisphere. In winter 2020/21, this large-scale pattern underwent a significant and intense subseasonal re.....»»
Tourists help scientists reveal microplastic pollution on remote Arctic beaches
Tourists acting as citizen scientists have helped a research team detect microplastics on remote Arctic beaches. The global scale of plastic production means that these tiny fragments of plastic are now ubiquitous, and scientists fear that ocean curr.....»»
An Abandoned Arctic Military Base Just Spilled a Scientific Secret
During the Cold War, the US built a network of tunnels in the Greenland ice sheet. Sixty years later, the base has provided a critical clue about the climate crisis......»»
Asymmetry in China"s mountain glaciers irreversibly changes the landscape
Earth has experienced significant changes in its climate over the past ~2.6 million years (the Quaternary) with a series of glacial and interglacial cycles that have transformed our landscapes. This involves erosive action directly from glaciers movi.....»»
Lessons from the sun: How studying solar cycles can create a safer future on Earth
In 1859, the Carrington Event, the most intense geomagnetic storm in recorded history, created spectacular auroral displays around the globe, illuminating the night skies so brightly that birds began singing and laborers set off for work, mistakenly.....»»
Scientists unravel evolutionary history of the Arctic flora
A team led by Prof. Wang Wei from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has unraveled the evolutionary history of the Arctic flora. The study was published in Nature Communications......»»
Nvidia debuts Portal: Prelude RTX, and you can play it for free
Nvidia is launching Portal: Prelude RTX, a prequel to the main game based on a mod. It's packed full of RTX goodies, including DLSS 3 and ray tracing......»»
Is fast fashion slowing down? How global trade is being used as a "force for good"
In the world of fast fashion, where trends are born as quickly as they are discarded, global trade regulations have struggled to keep pace with relentless cycles of production and consumption......»»
The Arctic Is a Freezer That’s Losing Power
As glaciers retreat, methane-rich groundwater is bubbling to the surface. That may be warming the climate, accelerating the Arctic’s rapid decline......»»
Linux could be 3% of global desktops. What happened to Windows?
Linux gains (or loses), Windows slumps, macOS jumps—it's been quite a year. How can you argue against these numbers? (credit: 20th Century Fox / Aurich Lawson) According to one measurement by one firm, Linux reached 3......»»
The Microplastic Crisis Is Getting Exponentially Worse
Plastic production is skyrocketing, pushing microplastic pollution to dangerous new levels. Now research shows even the Arctic is increasingly contaminated......»»
Considerable but unsustainable water supply from thawing permafrost on the Tibetan Plateau in a changing climate
In a warming climate, the sustainability of cryospheric meltwater on the Tibetan Plateau has raised concerns because of its importance for the fragile ecosystem in the headwater regions and the dense populations in the downstream. Existing studies ma.....»»
