Unraveling a paradox of Himalayan glacier melt
One in five glaciers on Earth are covered with a layer of rocky debris. The presence of debris influences how glaciers melt. In the Himalaya, debris covers most large glaciers, and it is so thick that it should insulate the ice, slowing the rates of.....»»
Unraveling the mathematics behind wiggly worm knots
For millennia, humans have used knots for all kinds of reasons—to tie rope, braid hair, or weave fabrics. But there are organisms that are better at tying knots and far superior—and faster—at untangling them......»»
Unraveling the mechanism of green emission peaks in single polyfluorene chains
Molecular aggregates are clusters of small molecules held together by relatively weak forces believed to be originating from electronic interactions between the molecules. Owing to their exceptional photophysical properties, molecular aggregates find.....»»
First heat wave of the year set to bake Sierra Nevada snowpack: "The big melt is now here"
After weeks of uncertainty, forecasters say an incoming California heat wave will trigger rapid snowmelt on the slopes of the Sierra Nevada and cause more flooding in portions of the San Joaquin and Owens valleys this week......»»
How Warming Upended One of Greenland"s Most Stable Glaciers
Greenland’s Steenstrup Glacier doubled its annual ice loss in just a few years, thanks to warm ocean water.....»»
"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......»»
Goodbye, coolers. The EcoFlow Glacier doesn’t need ice — it makes it
With just a bit of sun, the superefficient EcoFlow Glacier kept our beer cold and our ice frozen without ever running out of battery......»»
Where will California"s record snowpack melt into floods? It"s complicated
After months of heavy rain across California and record snow in the southern Sierra Nevada, state officials warn that melting snow could turn into flooding as the state's skies turn sunnier this spring and summer......»»
Cutting cable bacteria with a laser puts an end to a bacterial party
The party-poopers cutting the cable bacteria are researchers from the Center for Electromicrobiology (CEM) at Aarhus University. The center's work focuses on unraveling the mysteries of how cable bacteria work......»»
Scientists in Arctic race to preserve "ice memory"
Scientists camped in the Arctic are set to start drilling to save samples of ancient ice for analysis before the frozen layers melt away due to climate change, mission organizers said on Monday......»»
Research reveals hidden ice melt in the greater Himalaya
A new study reveals that the mass loss of lake-terminating glaciers in the greater Himalaya has been significantly underestimated, due to the inability of satellites to see glacier changes occurring underwater, with critical implications for the regi.....»»
As glaciers retreat, new streams for salmon
Insects move in, alders and willows spring up, and spawning fish arrive in thousands. Enlarge / Wolf Point Creek is likely the most-well-studied glacier-fed stream in the world. (credit: Elizabeth via Flickr (CC BY-NC 2.0)).....»»
Highly charged ions melt nano gold nuggets
Normally, we have to make a choice in physics: Either we deal with big things—such as a metal plate and its material properties, or with tiny things—such as individual atoms. But there is also a world in between: The world of small but not yet ti.....»»
The Greenland Ice Sheet is close to a melting point of no return, says new study
The Greenland Ice Sheet covers 1.7 million square kilometers (660,200 square miles) in the Arctic. If it melts entirely, global sea level would rise about 7 meters (23 feet), but scientists aren't sure how quickly the ice sheet could melt. Modeling t.....»»
New research highlights an overlooked accelerant of ice loss from Antarctica"s Thwaites Glacier
In West Antarctica, the 80-mile-wide stream of sliding ice at the heart of Thwaites Glacier is likely to creep outward over the next 20 years, a change that could speed up ice loss, new research finds......»»
Unraveling nature"s chorus: AI detects bird sounds in Taiwan"s montane forests
Montane forests, known as biodiversity hotspots, are among the ecosystems facing threats from climate change. To comprehend potential impacts of climate change on birds in these forests, researchers set up automatic recorders in Yushan National Park,.....»»
Solving the paradox of how animals managed to evolve with bright colors without being eaten
A trio of evolutionary biologists, two with Carleton University, the other with Seoul National University, has apparently solved the paradox of aposematism—how animals managed to evolve with bright colors to warn predators of their toxic nature. In.....»»
Drought over? Spring outlook finds relief—and flood risk
Record snowfall and rain have helped to loosen drought's grip on parts of the western U.S. as national forecasters and climate experts warned Thursday that some areas should expect more flooding as the snow begins to melt......»»
3D radar scan provides clues about threats to iconic Alaskan glacier
A detailed "body scan" of Malaspina Glacier, one of Alaska's most iconic glaciers, revealed that its bulk lies below sea level and is undercut by channels that may allow ocean water to gain access, should its coastal barrier erode. This makes the gla.....»»
Modern glacier remains found near Mars equator suggest water ice possibly present today at low latitudes
In a groundbreaking announcement at the 54th Lunar and Planetary Science Conference held in The Woodlands, Texas, scientists revealed the discovery of a relict glacier near the equator of Mars. Located in Eastern Noctis Labyrinthus at coordinates 7°.....»»
Humans are leaving behind a "frozen signature" of microbes on Mount Everest
Almost 5 miles above sea level in the Himalayan mountains, the rocky dip between Mount Everest and its sister peak, Lhotse, lies windswept, free of snow. It is here at the South Col where hundreds of adventurers pitch their final camp each year befor.....»»
