"Devastating" melt of Greenland, Antarctic ice sheets found
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study......»»
Climate tipping points could be triggered by "committed warming"
As the planet warms, climate tipping points, such as the melting of ice sheets or loss of the Amazon rainforest, become increasingly likely......»»
Study finds Greenland"s glacier retreat rate has doubled over past two decades
Greenland's thousands of peripheral glaciers have entered a new and widespread state of rapid retreat, a Northwestern University and University of Copenhagen study has found......»»
New AI system can map giant icebergs from satellite images 10,000 times faster than humans
Scientists have trained an artificial intelligence (AI) system to accurately map—in one-hundredth of a second—the surface area and outline of giant icebergs captured on satellite images. The paper, titled "Mapping the extent of giant Antarctic ic.....»»
Researchers hunt for hard-to-spot genetic links to improve crop and livestock breeding
When a hurricane-like derecho knocked down corn plants across Iowa in August 2020, it was devastating for farmers. But it also presented a natural experiment for an Iowa State University research team, which fanned out across flattened fields in the.....»»
Crumpled sheets reveal a mechanism for glassy relaxations
We often crumple a scrap piece of paper into a ball before throwing it. This mundane action, however, creates a unique complex system with surprising mechanical properties. Take a thin plastic sheet such as cellophane and try it yourself. While a reg.....»»
Melting ice, falling snow: Sea ice declines enhance snowfall over West Antarctica
As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise, according to Penn State scientists......»»
Extracellular vesicles captured by sustainable wood cellulose-based nanofiber may identify and improve cancer treatment
A research team in Japan, led by Nagoya University's Akira Yokoi, has developed an innovative technique using cellulose nanofiber (CNF) sheets derived from wood cellulose to capture extracellular vesicles (EVs) from fluid samples and even organs duri.....»»
Study shows willow bark extract has broad-spectrum antiviral effect
From a seasonal cold to a stomach bug, nobody likes catching a virus—and epidemics can be devastating. We need safe, sustainable antiviral options to treat the outbreaks of the future. Scientists in Finland have now shown that an extract of willow.....»»
A Major Alarm Is Flashing Under Greenland’s Ice
Greenland’s northern ice shelves have lost more than a third of their volume since 1978, new research finds......»»
Data show Greenland"s ice shelves have lost more than a third of their volume since 1978
The largest floating ice shelves in the polar ice sheet have lost more than a third of their volume since 1978. In a study published on Nov. 7 in Nature Communications, scientists from the CNRS, alongside their Danish and American colleagues, have es.....»»
Outdated cryptographic protocols put vast amounts of network traffic at risk
Cryptography is largely taken for granted – rarely evaluated or checked – a practice that could have devastating consequences for businesses as attack surfaces continue to expand, the cost of a data breach rises year-over-year, and the age of qua.....»»
New study sheds light on Adélie penguins" reliance on declining sea ice during molt
A study published in the Proceedings of the National Academy of Sciences underscores the pivotal role that seasonal Antarctic sea ice plays in the annual molting periods of Adélie penguins......»»
2023 ozone hole ranks 16th largest, NASA and NOAA researchers find
The 2023 Antarctic ozone hole reached its maximum size on Sept. 21, according to annual satellite and balloon-based measurements made by NASA and NOAA. At 10 million square miles, or 26 million square kilometers, the hole ranked as the 12th largest s.....»»
Former head of NASA’s climate group issues dire warning on warming
Conclusion that decrease in aerosol pollution will drive temps higher sparks backlash. Enlarge (credit: Alexandros Maragos / Getty Images) During the past year, the needles on the climate dashboard for global ice melt, h.....»»
Hydrogeologists develop innovative way to predict saltwater intrusion into groundwater
As the world warms and ice sheets melt, the ocean continually rises. The greater Boston area can expect to see between one and six feet of sea level rise by 2100, according to recent estimates......»»
Bird Flu Reaches the Antarctic for the First Time
As the first known cases of H5N1 are detected in the region, scientists fear for the isolated penguin and seal populations that have never been exposed......»»
This is how we could possibly build paved roads on the Moon
Lasers melt a regolith-like material into pavers that could be used for lunar roads. Enlarge (credit: Master/Getty) The Moon is slated to be our next frontier. When Artemis 3 takes off (tentatively) near the end of 2025,.....»»
Meltwater flowing beneath Antarctic glaciers may be accelerating their retreat
A new Antarctic ice sheet modeling study from scientists at UC San Diego's Scripps Institution of Oceanography suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster......»»
Underwater robot finds new circulation pattern in Antarctic ice shelf
More than merely cracks in the ice, crevasses play an important role in circulating seawater beneath Antarctic ice shelves, potentially influencing their stability, finds Cornell University-led research based on a first-of-its-kind exploration by an.....»»
Gene discovery may help growers battle grape downy mildew
Researchers at Cornell have discovered a new grape downy mildew resistance gene—giving the wine and grape industry a powerful new tool to combat this devastating disease......»»
