What lies beneath melting glaciers and thawing permafrost?
Around the planet, ice is rapidly disappearing. From mountain tops, the poles, the seas, and the tundra. As the ice melts, it's exposing new surfaces, new opportunities, and new threats—including valuable mineral deposits, archaeological relics, no.....»»
Weather "whiplash" in Antarctica may help predict effects of future climate change
The McMurdo Dry Valleys of Antarctica live up to their name. The region is one of the driest places on Earth—mountains form a wall around the valleys and prevent melting glacier water from intruding, humidity is extremely low, and no rain was docum.....»»
Hazardous Melting Ice Could Sink Arctic Shipping
Warmer temperatures were supposed to make Arctic shipping easier. But thick floating ice created by local melting is a bigger risk than people realized.....»»
Scientists equip Australian sea lions with cameras to explore previously unmapped ocean habitats
What lies deep beneath ocean surfaces is often a mystery. In Australia, many underwater habitats have not been mapped, and researchers know little about them. Now, scientists are working to change that by employing sea lions as videographers......»»
Retreating Andean rocks signal the world"s glaciers are melting far faster than predicted, report scientists
Rocks recently exposed to the sky after being covered with prehistoric ice show that tropical glaciers have shrunk to their smallest size in more than 11,700 years, revealing the tropics have already warmed past limits last seen earlier in the Holoce.....»»
3D terrestrial laser scanner assists in reconstructing glacier"s mass balance sequence
Complex topography of glacier surfaces under accelerating global warming presents unprecedented challenges to traditional methods of glaciological observation due to intense fragmentation and differential melting......»»
Hidden players in climate change: How microscopic proteins could shape our future
In the narrative about climate change, we often focus on the big and visible—like shrinking glaciers and churning hurricanes. But there's another world, microscopic and hidden, that's just as crucial and the focus of a new study by Amy Gladfelter,.....»»
Underwater mapping reveals new insights into melting of Antarctica"s ice shelves
An international research team—including scientists from the University of East Anglia (UEA)—deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica. The underwater vehicle, "Ran," was programmed to dive into the cavity.....»»
New methods predict tipping points for alpine permafrost loss
If the bedrock in the Alps no longer remains permanently frozen, rockfalls may occur more frequently. By measuring electrical resistivity in the ground, researchers can now better understand why this happens......»»
Hubble images NGC 3430, a classic spiral galaxy
This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor......»»
Underground CO₂ storage: Researchers measure carbon mineralization at unprecedented small scale
As we look to the sky above and ponder one of the biggest questions of our time—how to combat the carbon emissions that are driving climate change—a potential answer just may lie beneath our feet, in Earth's deep subsurface......»»
Chemical analyses find hidden elements from renaissance astronomer Tycho Brahe"s alchemy laboratory
In the Middle Ages, alchemists were notoriously secretive and didn't share their knowledge with others. Danish Tycho Brahe was no exception. Consequently, we don't know precisely what he did in the alchemical laboratory located beneath his combined r.....»»
New study supports stable mantle chemistry dating back to Earth"s early geologic history
A new analysis of rocks thought to be at least 2.5 billion years old by researchers at the Smithsonian's National Museum of Natural History helps clarify the chemical history of Earth's mantle—the geologic layer beneath the planet's crust......»»
The worst gadget of 2024 has a killer camera feature
The Rabbit R1 isn't very good, but beneath the mediocre camera hides a really cool feature that just might make it worth buying after all......»»
How mantle hydration changes over the lifetime of a subduction zone
Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the mantle above it, contributing to the formation of vol.....»»
Signatures of life could survive near surfaces of the moons Enceladus and Europa, NASA experiment suggests
Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have evidence of oceans beneath their ice crusts. A NASA experiment suggests that if these oceans support life, signatures of that life in the form of organic molecules (e.g. amino acids, nu.....»»
Fighting AI-powered synthetic ID fraud with AI
Aided by the emergence of generative artificial intelligence models, synthetic identity fraud has skyrocketed, and now accounts for a staggering 85% of all identity fraud cases. For security professionals, the challenge lies in staying one step ahead.....»»
Freezing and melting reshape diversity and structure of glacier microbial communities
With the increasing attention on global climate change and glacier retreat, the study of glacier microbiota has gradually become an important field of research......»»
Bennu asteroid samples unveiled
In a discreet vacuumed-packed container inside a FedEx box lies a piece of ancient history; extremely ancient history......»»
Existence of lunar lava tube cave demonstrated
The presence of conduits below the lunar surface has been theorized and extensively debated for at least 50 years. Now, an analysis of NASA Lunar Reconnaissance Orbiter radar data reveals what lies below the Mare Tranquillitatis......»»
As alpine glaciers melt, the corpses of long-lost climbers are being discovered in the ice
In late June, as a group of mountaineers descended a treacherous glacier high in the Peruvian Andes, they spotted a dark, out-of-place lump resting on the blinding white snow......»»
