Effectively removing carbon dioxide from the atmosphere
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have investigated the extent to which direct capture of carbon dioxide (CO2) from the ambient air can help to effectively remove greenhouse gasses from the atmosphere. The result: With car.....»»
Modern aircraft emit less carbon than older aircraft, but their contrails may do more environmental harm
Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found......»»
How efficiently different US forests will remove atmospheric carbon in the future
Forests absorb carbon by capturing carbon dioxide from the atmosphere, making forest carbon stocks an important resource against climate change. In research published in Ecology and Evolution, investigators examined existing tree regeneration pattern.....»»
Researchers propose "carbon removal budget" to tackle climate change
New research from the University of Oxford, published in the journal Carbon Management, makes the case for a novel Carbon Removal Budget to help tackle climate change. It would sit alongside the Carbon Budget that governs how much CO2 can safely be e.....»»
Forests destroyed by wildfires emit carbon long after the flames die—new study
Even in Earth's high northern-latitude forest, climate change is predicted to make wildfires more frequent and severe......»»
Molecules boost from metallic carbon nanotubes
A Lawrence Livermore National Laboratory (LLNL) team has found that pure metallic carbon nanotubes are best at transporting molecules......»»
Apple removes Carousel in Photos as part of changes based on iOS 18 beta feedback
Alongside a new Distraction Control feature for Safari, today’s release of iOS 18 beta 5 also brings some notable changes to the Photos app. In response to user feedback, Apple has made changes to the Photos interface, such as removing the new Caro.....»»
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.....»»
Researchers identify useful emission lines in the sun"s outer atmosphere
When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are par.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
New compound found to be effective against "flesh-eating" bacteria
Researchers at Washington University School of Medicine in St. Louis have developed a novel compound that effectively clears bacterial infections in mice, including those that can result in rare but potentially fatal "flesh-eating" illnesses. The com.....»»
Machine learning discovers "hidden-gem" materials for heat-free gas separation
Chemical separation, including gas separation, is a common process that is required for manufacturing and research. It accounts for a whopping 15% of U.S. energy consumption and produces millions of tons of carbon emissions......»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
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.....»»
Scientists find a human "fingerprint" in the upper troposphere"s increasing ozone
Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun's harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant.....»»
Chemical and transportation industries could boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources—such as solar and wind—promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene.....»»
Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»
Researchers discover graphene flakes in lunar soil sample
A study, published in National Science Review, reveals the existence of naturally formed few-layer graphene, a substance consisting of carbon atoms in a special, thin-layered structure......»»
Getting to the root of a plant"s success
Plants are powerful factories—they can turn basic ingredients like carbon dioxide, water, and sunlight into oxygen, sugars, and plant mass. But plants don't do all of this work on their own......»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
Scientists discover entirely new wood type that could be highly efficient at carbon storage
Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood......»»
