Microbes fuelled by wind-blown mineral dust melt the Greenland ice sheet
Scientists have identified a key nutrient source used by algae living on melting ice surfaces linked to rising sea levels.The Greenland ice sheet—the second largest ice body in the world after the Antarctic ice sheet—covers almost 80% of the surf.....»»
Measuring moon dust to fight air pollution
Moon dust, or regolith, isn't like the particles on Earth that collect on bookshelves or tabletops—it's abrasive and it clings to everything. Throughout NASA's Apollo missions to the moon, regolith posed a challenge to astronauts and valuable space.....»»
A Huge Tsunami Caused by a Thinning Glacier Created a Seismic Event for Nine Days
Scientists have traced a baffling monotonous planetary hum that lasted for nine days back to a glacier in Greenland.....»»
Synthetic mini-motor: Researchers convert chemical energy into rotational energy at the supramolecular level
Researchers at the Technical University of Munich (TUM) have developed an artificial motor at the supramolecular level that can develop impressive power. This wind-up motor is a tiny ribbon made of special molecules. When energy is applied, this ribb.....»»
Apple software leaks new Mac mini with five USB-C ports ahead of rumored event
Apple often launches Macs and iPads in October, after the iPhone dust settles. Enlarge / Apple's M3 Max-powered 16-inch MacBook Pro. New Pro laptops and some desktops could be on tap for later this fall. (credit: Andrew Cunningha.....»»
An AI tool for scanning sand grains opens windows into recent time and the deep past
Stanford researchers have developed an artificial intelligence-based tool—dubbed SandAI—that can reveal the history of quartz sand grains going back hundreds of millions of years. With SandAI, researchers can tell with high accuracy if wind, rive.....»»
Cloud as stumbling block for the propagation of the Southern Annular Mode
The Southern Annular Mode (SAM), with an iconic dipolar zonal wind pattern centered around the axis of the storm track, is the most dominant mode of variability orchestrating the weather and wind from the subtropics to the poles. Its origin, maintena.....»»
Deep design produces "butterfly" phase mask for light-sheet fluorescence microscopy
Researchers have introduced a solution to the problem of light-sheet fluorescence microscopy: novel illumination beams designed based on deep learning using a trainable phase mask. Their study eliminates the need for sophisticated optical design tool.....»»
Is the Apple iPhone 16 waterproof?
The iPhone 16 lineup is a tough series of phones, but they aren't completely immune to damage from dust and moisture......»»
Bizarre, nine-day seismic signal caused by epic landslide in Greenland

Climate change is accelerating extreme melting in Greenland with global impacts, says study
Climate change is accelerating the melting of ice in Greenland at an alarming rate, with serious implications not only for the Arctic, but also for the global climate, including Europe. According to a study led by researchers at the University of Bar.....»»
An evolutionary battleground: Plants vs. microbes
Gazing out on a freshwater pond, you may see tiny green plants with oval-shaped leaves floating in clusters. In overgrown ponds, these plants coat the water's surface. These plants—called duckweed or water lentils—can grow so fast that they can d.....»»
Rapid loss of Antarctic ice after 2100 likely under current emissions, climate scientists find
A Dartmouth-led study by more than 50 climate scientists worldwide provides the first clear projection of how carbon emissions may drive the loss of Antarctica's ice sheet over the next 300 years......»»
Discovery about ice layer formation in ice sheets can improve sea level rise predictions
A newly discovered mechanism for the flow and freezing of ice sheet meltwater could improve estimates of sea level rise around the globe......»»
Starship Super Heavy breezes through wind tunnel testing at NASA Ames

International team decodes the genome of the Greenland shark
The Greenland Shark (Somniosus microcephalus), an elusive dweller of the depths of the northern Atlantic and the Arctic Ocean, is the world's longest-living vertebrate, with an estimated lifespan of about 400 years......»»
New research sinks old theory for the doldrums, a low-wind equatorial region that stranded sailors for centuries
During the Age of Sail, sailors riding the trade winds past the equator dreaded becoming stranded in the doldrums, a meteorologically distinct region in the deep tropics. For at least a century, scientists have thought that the doldrums' lack of wind.....»»
Found dead in the snow: How microbes can help pinpoint time of death for forensic investigations in frigid conditions
What happens to a dead body in an extremely cold environment? Does it decompose? How do these conditions affect how forensic scientists understand when the person died?.....»»
The Golden Age of offbeat Arctic research
The Cold War spawned some odd military projects that were doomed to fail. Enlarge / At the US Army’s Camp Century on the Greenland ice sheet, an Army truck equipped with a railroad wheel conversion rides on 1,300 feet of track.....»»
Just how dangerous is Great Salt Lake dust? New research looks for clues
As Utah's Great Salt Lake shrinks, exposing more of its playa, concerns grow about the dust the dry lakebed emits. But scientists lack the data to fully understand what pollutants are present in these airborne sediments......»»
Researcher helps develop new technique to explore oceanic microbes
When Southern Methodist University (SMU) researcher Alexander Chase was a young boy, the sheer diversity of plants in Earth's tropical rainforests fascinated him. He found himself wondering what new species were out there, waiting to be unearthed. Th.....»»
