Microbes feast on crushed rock in subglacial lakes beneath Antarctica
Pioneering research has revealed the erosion of ancient sediments found deep beneath Antarctic ice could be a vital and previously unknown source of nutrients and energy for abundant microbial life......»»
Study yields new insights into the link between global warming and rising sea levels
A McGill-led study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the curre.....»»
Groundwater plays an invisible role supporting lakes
Nearly 90% of North America's lakes are located in Canada. That's why they make up such an enormous part of our landscape. Among their many vital functions, lakes are essential to the biodiversity of our territory and constitute indispensable oases f.....»»
More microbes found that break down the carbon-fluorine bonds found in some unsaturated PFAS
A team of chemical and environmental engineers at the University of California Riverside, working with colleagues from the University of California Los Angeles, has found a class of microbes that consume PFAS in the environment and sever some of the.....»»
Ancient Antarctic microorganisms are aggressive predators
In Antarctica there is a small lake, called Deep Lake, that is so salty it remains ice-free all year round despite temperatures as low as -20°C in winter. Archaea, a unique type of single-celled microorganism, thrive in this bitterly cold environmen.....»»
EVs are holding strong, but U.S. elections may rock the boat, report finds
The midyear Market Outlook Report from Dave Cantin Group and Kaiser Associates found that EV sales are starting to drive steady growth. Meanwhile, a volatile political landscape and Supreme Court decisions complicate auto industry plans......»»
Peregrine falcons mount a comeback in Yosemite, thanks to rock climbers
Four decades ago, fragile falcon eggs were saved from certain death by Ken Yager and a small team of expert climbers from a nest on Yosemite's El Capitan sheer granite wall, as protective parents dive-bombed from the sky......»»
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.....»»
Engineered microbes found to repel mosquitoes
Genetically-engineered human skin bacteria can make mice less attractive to mosquitoes for 11 days. Mosquitoes transmit a host of deadly diseases, including malaria, West Nile, dengue, yellow fever, and Zika. Female mosquitoes on the hunt for a blood.....»»
Has NASA found evidence of ancient life of Mars? An expert examines the latest discovery
NASA has announced the first detection of possible biosignatures in a rock on the surface of Mars. The rock contains the first martian organic matter to be detected by the Perseverance rover, as well as curious discolored spots that could indicate th.....»»
The Galapagos Islands and many of their unique creatures are at risk from warming waters
Warm morning light reflects from the remains of a natural rock arch near Darwin Island, one of the most remote islands in the Galapagos. In clear, deep blue water, thousands of creatures—fish, hammerhead sharks, marine iguanas—move in search of f.....»»
NASA Mars rover captures rock that could hold fossilized microbes
NASA's Perseverance Mars rover has made what could be its most astonishing discovery to date: possible signs of ancient life on the Red Planet......»»
No, NASA hasn’t found life on Mars yet, but the latest discovery is intriguing
"These spots are a big surprise." Enlarge / NASA’s Perseverance rover discovered “leopard spots” on a reddish rock nicknamed “Cheyava Falls” in Mars’ Jezero Crater in July 2024. (credit: NASA/JPL-Caltech/MSSS).....»»
Polluted Lakes Are Being Cleansed Using Floating Wetlands Made of Trash
Platforms combining plants and recycled garbage could offer a cut-price solution for reviving polluted bodies of water......»»
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......»»
Perseverance rover discovers rock with potential signs of ancient life
A vein-filled rock is catching the eye of the science team of NASA's Perseverance rover. Nicknamed "Cheyava Falls" by the team, the arrowhead-shaped rock contains fascinating traits that may bear on the question of whether Mars was home to microscopi.....»»
Rock art and archaeological record reveal man"s complex relationship with Amazonian animals
Rock art explored by archaeologists in the Colombian Amazon has provided an insight into the complex relationship between the earliest settlers on the continent and the animals they encountered......»»
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.....»»
Scientists publish first experimental evidence for new groups of methane-producing organisms
A team of scientists from Montana State University has provided the first experimental evidence that two new groups of microbes thriving in thermal features in Yellowstone National Park produce methane—a discovery that could one day contribute to t.....»»
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......»»
