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.....»»
15,000-year-old viruses discovered in Tibetan glacier ice
Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cata.....»»
The paradox of a free-electron laser without the laser
A new way of producing coherent light in the ultra-violet spectral region, which points the way to developing brilliant table-top X-ray sources, has been produced in research led at the University of Strathclyde......»»
Mapping extreme snowmelt and its potential dangers
Snowmelt—the surface runoff from melting snow—is an essential water resource for communities and ecosystems. But extreme snow melt, which occurs when snow melts too rapidly over a short amount of time, can be destructive and deadly, causing flood.....»»
Match matters: The right combination of parents can turn a gene off indefinitely
A new study provides a potential tool for unraveling the mystery of how experiences can cause inheritable changes to an animal's biology. By mating nematode worms, they produced permanent epigenetic changes that lasted for more than 300 generations......»»
Oil spills" impacts on Canadian arctic, the environment and indigenous peoples
The growing rate of ice melt in the Arctic due to rising global temperatures has opened up the Northwest Passage (NWP) to more ship traffic, increasing the potential risk of an oil spill and other environmental disasters. A new study published in the.....»»
Unraveling the mechanisms that create the individualized metabolism in leukemia
Lysine-specific demethylase 1 (LSD1), an enzyme involved in gene expression, produces individualized metabolism depending on the type of acute myeloid leukemia cells. Cancer cells have a unique ability to metabolize substances differently from normal.....»»
Glacial melt in High Mountain Asia accelerating as summers warm
Glaciers in High Mountain Asia have been melting more quickly in recent years due to rising summer temperatures. Glacier melt prevails now even in areas where glaciers were previously growing, a team of researchers led by the University of St Andrews.....»»
Underwater seismometer can hear how fast a glacier moves
Scientists show that an ocean-bottom seismometer deployed close to the calving front of a glacier in Greenland can detect continuous seismic radiation from a glacier sliding, reminiscent of a slow earthquake......»»
Mountaintop glacier ice disappearing in tropics around the world
Mountaintop glacier ice in the tropics of all four hemispheres covers significantly less area—in one case as much as 93% less—than it did just 50 years ago, a new study has found......»»
There"s more to genes than DNA: How Mum and Dad add something extra
Biologists at the Universities of Bath and Vienna have discovered 71 new 'imprinted' genes in the mouse genome, a finding that takes them a step closer to unraveling some of the mysteries of epigenetics—an area of science that describes how genes a.....»»
Long-term Himalayan glacier study: Geographers combine historical images and maps with current data
The glaciers of Nanga Parbat—one of the highest mountains in the world—have been shrinking slightly but continually since the 1930s. This loss in surface area is evidenced by a long-term study conducted by researchers from the South Asia Institut.....»»
The most ancient ice in the Alps will be preserved in Antarctica
The Ice Memory international mission on Monte Rosa has been accomplished. After working for five days at 4,500 meters in the accumulation zone of the Grenzgletscher, the glacier saddle of Colle Gnifetti, scientists extracted three shallow ice cores (.....»»
Glacier Blood? Watermelon Snow? Whatever It"s Called, Snow Shouldn"t Be So Red.
Winter through spring, the French Alps are wrapped in austere white snow. But as spring turns to summer, the stoic slopes start to blush. Parts of the snow take on bright colors: deep red, rusty orange, lemonade pink. Locals call this "sang de glacie.....»»
Pine Island Glacier"s ice shelf is ripping apart, speeding up key Antarctic glacier
For decades, the ice shelf helping to hold back one of the fastest-moving glaciers in Antarctica has gradually thinned. Analysis of satellite images reveals a more dramatic process in recent years: From 2017 to 2020, large icebergs at the ice shelf's.....»»
Climate change and melting glaciers have widely varied impacts on Asian water supplies
Climate change is causing mountain snow to melt more rapidly and glaciers to shrink, but this is making a widely varied impact on water supplies in Asia, a new paper by PSI Senior Scientist Jeffrey Kargel says......»»
Evolutionary secrets of the gut microbiome
How does our gut respond and adapt to changing conditions? Where does this fundamental and critical flexibility come from? Technion scientists are unraveling the genius of the gut's microbiome, through microbiota, all the way to genetic inversion......»»
Candle box from 500 years ago found in melting glacier in Norway
A team of archaeologists with the Glacier Archaeology Program in Innlandet have discovered a candle box in the Lendbreen glacier in Norway's Breheimen National Park. The team has been posting its findings on their Facebook page......»»
Geologists Marvel at Alaska Glacier"s Rare "Surge" -- Up to 60 Feet a Day
The hills of ice at the base of Alaska's Muldrow Glacier "have sat undisturbed and covered by tundra for more than 60 years," reports the Washington Post, adding that in normal years the glacier only moves about three inches a day. But that's sudde.....»»
Applying mathematics takes "friendship paradox" beyond averages
The friendship paradox is the observation that the degrees of the neighbors of a node within any network will, on average, be greater than the degree of the node itself. In other words: your friends probably have more friends than you do......»»
Scientist identifies signaling underlying regeneration
The mystery of why salamanders can regenerate a lost limb, but adult mammals cannot has fascinated observers for thousands of years. Now, a team of scientists has come a step closer to unraveling that mystery with the discovery of differences in mole.....»»
