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......»»
Satellite-derived data on artificial light at night indicate rapidly increasing industrial activities in the Arctic
More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urb.....»»
Targeting bacteria: Auxiliary metabolic genes expand understanding of phages and their reprogramming strategy
Viruses that infect bacteria—known as bacteriophages—could be used in a targeted manner to combat bacterial diseases. They also play an important ecological role in global biogeochemical cycles. Recent research by researchers at the University of.....»»
A new Tron game is coming next year, and it’s got Light Cycles
Big Fan Games' first licensed project is Disney Tron: Catalyst, a top-down adventure game set in the Arq Grid......»»
Ancient climate analysis reveals unknown global processes
According to highly cited conventional models, cooling and a major drop in sea levels about 34 million years ago should have led to widespread continental erosion and deposited gargantuan amounts of sandy material onto the ocean floor. This was, afte.....»»
Research vessel provides comprehensive assessment of the changing Central Arctic Ocean
Sparse sea ice, thousands of data points and samples, a surprising number of animals and hydrothermal vents—those are the impressions and outcomes that an international research team is now bringing back from a Polarstern expedition to the Central.....»»
"Party atmosphere": Skygazers treated to another aurora show
Scientist Jim Wild has traveled to the Arctic Circle numerous times to study the northern lights, but on Thursday night he only needed to look out of his bedroom window in the English city of Lancaster......»»
Declines in plant resilience threaten carbon storage in the Arctic
Rapid warming has impacted the northern ecosystem so significantly that scientists are concerned the region's vegetation is losing the ability to recover from climate shocks, suggests a new study......»»
Decades-long research reveals new understanding of how climate change may impact caches of Arctic soil carbon
Utilizing one of the longest-running ecosystem experiments in the Arctic, a Colorado State University-led team of researchers has developed a better understanding of the interplay among plants, microbes and soil nutrients—findings that offer new in.....»»
Arctic plant study suggests the rate of climate change threatens to exceed the adaptive capacity of species
A research group at the Finnish Museum of Natural History is investigating the adaptive potential of plant species amid a warming climate. Their recent study investigates the Siberian primrose, a plant species that occurs on the coasts of the Bothnia.....»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»

Study tracks traveling population wave in Canada lynx
A new study by researchers at the University of Alaska Fairbanks's Institute of Arctic Biology provides compelling evidence that Canada lynx populations in Interior Alaska experience a "traveling population wave" affecting their reproduction, movemen.....»»
Study elucidates a mechanism for phosphorus cycling in subtropical forests
Phosphorus (P) is an important nutrient element in plant photosynthesis. However, the adsorption of mineral P via leaching and erosion leads to a decrease in P availability and consequently P deficiency......»»
Retracing walrus ivory trade of Viking Age reveals early interactions between Europeans and Indigenous North Americans
By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trad.....»»
Saturday Citations: Octopuses as shift supervisors for fish; universe confounds standard model; extremely old cheese
This week, biologists tracked down a mysterious group of orcas near Chile; Hubble spotted a black hole jet that causes stars along its trajectory to erupt; and researchers explained mysterious craters that began appearing in Siberian permafrost in th.....»»
Study offers new explanation for Siberia"s permafrost craters
Mysterious craters that first appeared in the Siberian permafrost a decade ago were caused by climate change-driven pressure changes that explosively released methane frozen underground, a new study reports. The research offers a fresh take on the or.....»»
Heat, animal illness and erosion risks to affect NZ agriculture with changing climate
Scientists at Manaaki Whenua—Landcare Research have worked closely with researchers from NIWA, AgResearch and Plant & Food Research to model the likely risks of a warming climate across different agricultural sectors in New Zealand. The study is pu.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Arctic sea ice near historic low; Antarctic ice continues decline
Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline.....»»
UN chief says sea level rise threatens "rising tide of misery"
United Nations Secretary-General Antonio Guterres warned on Wednesday that rising sea levels threaten to create "a rising tide of misery" for millions, with intense storm surges, coastal erosion and coastal flooding increasingly likely......»»
