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.....»»
Marine dust identifies 1.5 million year Oldest Ice near South America
Earth's climate has experienced major shifts over its billions of years of history, including numerous periods where ice proliferated across the planet. Today, ice cores can be a valuable resource for understanding these periods of Earth's history as.....»»
The unexpected role of magnetic microbes in deep-sea mining
Polymetallic nodules are potato-sized formations on the ocean floor that are rich in minerals such as nickel, cobalt, and manganese. Their concentration of rare, economically important minerals has made the nodules the focus of controversial deep-sea.....»»
Turbulent solar wind originates in the sun"s corona, study shows
Solar wind is a never-ending stream of charged particles coming from the sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the sun's variable magnetic field, creating chaot.....»»
"Unsurvivable" Hurricane Helene races towards Florida
Parts of Florida face "unsurvivable" conditions when Hurricane Helene hits later Thursday, the US weather service said, warning that howling wind will drive destructive waves and storm surge as high as 20 feet (six meters) onto the low-lying coast......»»
Frozen in time: Rock fossils hint at Mars"s ancient climate
Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then call them paleo-bedform.....»»
Tailwinds don’t help “everesting” cyclists
"There are no clever tricks to get around the necessary diet and exercise." Enlarge / Physicist Martin Bier in an aerodynamic tuck, a cycling position that reduces wind resistance. (credit: Martin Bier) Many avid bicycli.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
New nanoparticle prevents mineral buildup in equipment handling water-oil mixtures
In the process of oil extraction, hard mineral buildup inside the pipes and equipment can cause serious operational damage, safety issues such as pipe explosion and significant economic losses. The current methods for descaling mineral buildup, howev.....»»
Spinning artificial spider silk into next-generation medical materials
It's almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano have made their own version of fake spider silk, but this one c.....»»
Evaluating changes in dissolved inorganic carbon in the Greenland Sea
To know whether we are complying with emission treaties, all CO2 must be traceable. Incomplete bookkeeping recently sent scientists on a search in the Greenland Sea. Their research is published in the Journal of Geophysical Research: Oceans......»»
"Doomsday" glacier set to melt faster and swell seas as world heats up, say scientists
Tidal action on the underside of the Thwaites Glacier in the Antarctic will "inexorably" accelerate melting this century, according to new research by British and American scientists. The researchers warn the faster melting could destabilize the enti.....»»
Phytoplankton shield ice shelves from summer heat
In spring, stretches of Antarctic sea ice melt to form pockets of open water called polynyas, which make perfect homes for phytoplankton. These marine microbes can become so abundant that they turn the water green......»»
The Dyson V15 cordless vacuum is $200 off for a limited time
The Dyson V15 Detect Extra cordless vacuum, which uses a green laser to reveal hidden dust, is available from Best Buy for only $600 following a $200 discount......»»
Genome sequence analysis identifies new driver of antimicrobial resistance
Antibiotics are a lifesaving tool. Yet, due to their chronic overuse, microbes are evolving and developing immunity against them. As a result, once-effective medications can no longer stave off infections, complicating treatment and increasing mortal.....»»
Oceanic life found to be thriving thanks to Saharan dust blown from thousands of kilometers away
Iron is a micronutrient indispensable for life, enabling processes such as respiration, photosynthesis, and DNA synthesis. Iron availability is often a limiting resource in today's oceans, which means that increasing the flow of iron into them can in.....»»
Location, location, location: Snowpack storage and runoff timing in burn scars depend on site and terrain
Increasingly severe wildfires at high elevations are impacting snowpack—an important reservoir for the U.S. West. The altered landscape makes it more challenging to predict when snow will melt and how much water will be available for use......»»
How humans are affecting the Northern Hemisphere"s wind patterns
The summer of 2024 was the hottest on record and, unfortunately, this came as no surprise. Summers have been getting hotter and drier around the world, including in the Northern Hemisphere, leading to intense droughts and heat waves in North America.....»»
Light-induced immunoassay can selectively detect coronavirus spike proteins in five minutes
Like moths to a flame, microbes can also be moved by light. Using this knowledge, researchers from Osaka Metropolitan University's Research Institute for Light-induced Acceleration System (RILACS) have demonstrated a method to detect the presence of.....»»
The Outrageous Scheme to Capture and Sell Greenland’s Meltwater
A startup says shipping meltwater from Greenland’s glaciers internationally will boost the local economy and could help ease water pressures in arid regions—but what does that actually mean for the world?.....»»
