Methane pulses on Mars possibly driven by atmospheric pressure changes
New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars's atmosphere; knowing when and where to look for methane can help the Curiosity rover search.....»»
Why are tweens so obsessed with Sephora? We asked them to find out.
TikTokkers say Sephora is overrun with tweens buying Drunk Elephant and Glow Recipe. To find out why, we went straight to the source. My first trip to Sephora was made possible by a popular girl in my grade who had a 13 Going On 30-themed birth.....»»
Top cybersecurity concerns for the upcoming elections
In this Help Net Security video, Adam Marrè, CISO at Arctic Wolf, explains how state and local governments must focus on cybersecurity as the 2024 election approaches in the United States. State and local IT and cybersecurity teams usually have few.....»»
Scientists warn missing Russian data causing Arctic climate blind spots
Loss of scientific data from Russia's Arctic monitoring stations following the invasion of Ukraine has worsened information gaps that could have serious implications for tracking and predicting climate change globally, researchers warned Monday......»»
Scientists retrieve rare methane hydrate samples for climate and energy study
A scientific drilling mission in the Gulf of Mexico has returned with 44 cores from a methane hydrate reservoir deep under the seafloor. Globally, energy-rich methane hydrates hold an estimated 15% of the world's organic carbon but are poorly underst.....»»
Federal rule forces oil states to cut planet-warming methane emissions
Within two years, a new federal rule will force oil- and gas-producing states to crack down on methane gas emissions—a major driver of climate change......»»
The pros and cons of oxygen mediating the performance of nickel catalysts in dry reforming of methane
Catalysis is one of the key technologies in the chemical industry and has a wide-reaching impact on various aspects of our daily lives, including plastics manufacturing, drug synthesis, and production of both fertilizers and fuels. It is estimated th.....»»
Improved mapping gives decision makers a new tool for protecting infrastructure as Arctic warms
New insights from artificial intelligence about permafrost coverage in the Arctic may soon give policymakers and land managers the high-resolution view they need to predict climate-change-driven threats to infrastructure such as oil pipelines, roads.....»»
Team upgrades technology for monitoring methane emissions
Researchers at the National Institute of Standards and Technology (NIST) have upgraded a highly precise technology designed to monitor emissions of methane, a critical greenhouse gas, and other trace gases, even in harsh field conditions. Measuring m.....»»
From Wildfires to Melting Sea Ice, the Warmest Summer on Record Has Had Cascading Effects across the Arctic
Climate change is already disrupting lives in the Arctic, and the warmest summer on record will certainly have an enormous impact on the people and wildlife of the region.....»»
What"s Behind the "Arctic Blast" Plunging into the U.S.?
This week’s cold snap across the U.S. will be one of “the most impressive Arctic outbreaks of this century,” one climate scientist says.....»»
Chasing the light: Study finds new clues about warming in the Arctic
The Arctic, Earth's icy crown, is experiencing a climate crisis like no other. It's heating up at a furious pace—four times faster than the rest of our planet. Sandia researchers are pulling back the curtain on the reduction of sunlight reflectivit.....»»
Methane activation by [LnO]+: The 4f orbital matters
As the "holy grail" in the field of chemistry, the catalytic activation of methane has been a topic of great interest in the field of heterogeneous catalysis. Gas-phase experiments provide an ideal platform for exploring catalytic reaction mechanisms.....»»
PFAS flow equally between Arctic Ocean and Atlantic Ocean, study finds
The frigid Arctic Ocean is far removed from the places most people live, but even so, "forever chemicals" reach this remote landscape. Now, research in Environmental Science & Technology Letters suggests that per- and polyfluoroalkyl substances (PFAS.....»»
Webb finds signs of possible aurorae on isolated brown dwarf
Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discov.....»»
Scientists collect eDNA samples in the extreme environment of the Arctic melting glaciers autonomously
What if there was a way to collect environmental DNA (eDNA) samples in extreme environments autonomously? And what if this method allowed the collection of more samples and to prevent risk of sample contamination? Portuguese researchers from the Inst.....»»
Breakthrough in nonoxidative coupling of methane: Direct conversion to propylene in low temperature
Nonoxidative coupling of methane (NOCM) exhibits promising prospect in that it affords value-added hydrocarbons and hydrogen with high atom economy. However, the challenge remains in methane's direct, selective conversion to more valuable hydrocarbon.....»»
Meat and dairy industry"s attempt to change how we measure methane emissions would let polluters off the hook
Lobbyists from major polluting industries were out in force at the recent UN climate summit, COP28. Groups representing the livestock industry, which is responsible for around 32% of global methane emissions, want to increase their use of a new way o.....»»
Study investigates influence of Arctic cold air on carbon dioxide uptake of the East Sea
The recent cold spell has plunged South Korean into a deep freeze, resulting in the closure of 247 national parks, the cancellation of 14 domestic flights, and the scrapping of 107 cruise ship voyages. While the cold snap brought relief by significan.....»»
