Uncovering the dominant contribution of intermediate volatility compounds to biomass-burning organic aerosols
Biomass burning, including wildfires and residential heating, emits a variety of air pollutants and has a series of negative impacts on the environment......»»
Biotic factors contribute more to aboveground biomass across scales
The aboveground biomass of vegetation is significant to the global carbon cycle and climate change mitigation. Both biotic factors, such as forest structure attributes, community-weighted mean of traits, and functional diversity, and abiotic factors,.....»»
Aerosols could be weakening summertime circulation in the Northern Hemisphere
Over the past several decades, summer jet streams (or west to east wind flow) and weather systems in the Northern Hemisphere have weakened. Projections suggest the trend will continue, which could make extreme heat events more likely and affect air q.....»»
Uncovering a centaur"s tracks: Scientists examine unique asteroid-comet hybrid
Although our solar system is billions of years old, we've only recently become better acquainted with one of its more dynamic and captivating inhabitants known as (2060) Chiron......»»
Layer by layer: How simulations help manufacturing of modern displays
Modern materials must be recyclable and sustainable. Consumer electronics is no exception, with organic light-emitting diodes (OLEDs) taking over modern televisions and portable device displays. However, the development of suitable materials—from t.....»»
What to do if your vacuum cleaner smells like burning
A burning smell can be a sign of mechanical failure – so turn your vacuum off immediately, then read this for the next steps......»»
Gladiator II: A historian on the real north African kingdom of Numidia—and the men who ruled it
"Gladiator II" opens with a Roman fleet brutally laying siege to a city in the north African kingdom of Numidia. On the big screen we see ships set ablaze by pots of burning oil and defenders impaled by man-sized iron bolts. The so-called barbarian i.....»»
New climate chemistry model finds "non-negligible" impacts of potential hydrogen fuel leakage
As the world looks for ways to stop climate change, much discussion focuses on using hydrogen instead of fossil fuels, which emit climate-warming greenhouse gases (GHGs) when they're burned. The idea is appealing. Burning hydrogen doesn't emit GHGs t.....»»
Metal-organic framework film improves isomer separation control
Researchers have developed a method to enhance the separation of chemical isomers by controlling molecular diffusion. Utilizing a metal-organic framework thin film, they applied dynamic chemical interactions to adjust pore dynamics and reverse isomer.....»»
Uncovering the evolutionary origins of the hepatitis E virus
An international team of virologists, mammalian ecologists and zoologists has uncovered the evolutionary origins of the hepatitis E virus. In their study, published in the Proceedings of the National Academy of Sciences, the group analyzed genomic da.....»»
As Christmas catering approaches, experts review food waste policies
Composting and green bins are making their mark on recycling organic waste, but Australian households are still responsible for millions of tons of greenhouse-gas emitting food waste ending up in landfill......»»
Rising desertification shows we can"t keep farming with fossil fuels
Three-quarters of Earth's land has become drier since 1990. Droughts come and go—more often and more extreme with the incessant rise of greenhouse gas emissions over the last three decades—but burning fossil fuels is transforming our blue planet......»»
Single heat wave wiped out millions of Alaska"s dominant seabird
The common murre, a large black-and-white seabird native to northern waters, has become far less common in Alaska over the past decade due to the impacts of climate change......»»
Air pollution has contributed to 16 million deaths in India in the past decade: Study
Several schools in Delhi close during winter for at least two weeks because of high air pollution levels. Every winter, widespread crop burning in north India and weather conditions add to the already high air pollution levels from traffic, industry.....»»
How to catch a supernova explosion before it happens—and what we can learn from it
Stars are born, live and die in spectacular ways, with their deaths marked by one of the biggest known explosions in the universe. Like a campfire needs wood to keep burning, a star relies on nuclear fusion—primarily using hydrogen as fuel—to gen.....»»
Kokumi compounds: The hidden enhancers in your sparkling wine
"Rich" and "full-bodied" are terms that people often use to describe the taste of wine. They are also the properties that kokumi compounds bring to foods like mature Gouda cheese, though scientists haven't widely explored them in wines. In the Journa.....»»
Supramolecular sorting machine separates aromatic and aliphatic compounds
How can aromatic compounds be separated from aliphatic compounds efficiently without having to rely on energy-intensive processes? In an article published in the journal Angewandte Chemie International Edition, chemists from Heinrich Heine University.....»»
Researchers call on European Commission to protect groundwater and subterranean life from pollution
The subterranean world holds a value that is often underestimated. Its significance seems to escape notice, particularly its vital role in storing drinking water—a resource long taken for granted—and its contribution to biodiversity, harboring un.....»»
A new global carbon trading market could be held hostage by speculators
Our planet's future hangs in the balance due to the unabated greenhouse gas emissions from burning fossil fuels. Treating these emissions as something that can be owned and exchanged in a market has been touted as a solution since the early 1990s, wh.....»»
Saturday citations: The "donut effect"; basically immortal batteries; Neanderthals and H. sapiens
This week, researchers studying data from NASA's Dawn mission reported the identification of 11 sites on Ceres that suggest an internal reservoir of organic materials. A multidisciplinary team published an analysis of the dazzle camouflage patterns d.....»»
