What is the carbon footprint of a hospital bed?
Researchers from the University of Waterloo completed the first-ever assessment of a Canadian hospital to reveal its total environmental footprint and specific carbon emission hotspots......»»
Enhanced rock weathering results in higher crop yields and improved crop health, study shows
Enhanced rock weathering—a nature-based carbon dioxide removal process that accelerates natural weathering—results in significantly higher first year crop yields, improved soil pH, and higher nutrient uptake, according to a paper, published in PL.....»»
How plants adjust their photosynthesis to changing light
Photosynthesis is the central process by which plants build up biomass using light, water, and carbon dioxide from the air. Gaining a detailed understanding of this process makes it possible to modify and thus optimize it—for example, with a view t.....»»
An inside look at how plants and mycorrhizal fungi cooperate
For millions of years, underground fungi have lived in symbiosis with plant roots. Plants provide photosynthesized carbon, while fungi deliver water and nutrients. In order to do so, these organisms share space at the cellular scale: fungi stretch a.....»»
A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»
Heat-trapping carbon dioxide and methane levels in the air last year spiked to record highs again
The levels of the crucial heat-trapping gases in the atmosphere reached historic highs last year, growing at near-record fast paces, according to the U.S. National Oceanic and Atmospheric Administration......»»
Sensitive interventions to catalyze China"s net-zero transition in energy and transport
The global energy transition could happen sooner than anticipated if sensitive intervention points are used to deliver China's carbon neutrality policy at the city-level, researchers from the University of Oxford and The Chinese University of Hong Ko.....»»
Africa"s carbon sink capacity is shrinking
The population of Africa, the second-largest continent in the world, currently sits at about 1.4 billion, but is set to exceed 2 billion by 2040. This means greater swaths of land than ever before are being used for agriculture, and livestock numbers.....»»
Mars may not have had liquid water long enough for life to form
Lab experiments suggest gullies on Mars might form when carbon dioxide heats up. Enlarge (credit: NASA/JPL-Caltech/University of Arizona) Mars has a history of liquid water on its surface, including lakes like the one th.....»»
Electric cars credited with lower carbon dioxide emissions in US neighborhoods
The booming use of electric vehicles in parts of California is reducing CO2 emissions in those areas, a study showed Thursday, bolstering a key pillar of the state's drive towards net zero......»»
Man pleads guilty to stealing former coworker’s identity for 30 years
Victim was jailed for 428 days after LA cops failed to detect true identity. Enlarge (credit: Malte Mueller | fStop) A high-level Iowa hospital systems administrator, Matthew Kierans, has admitted to stealing a coworker'.....»»
A new estimate of US soil organic carbon to improve Earth system models
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate.....»»
How AI and deeper roots can help soil store more carbon
In 2020, global agricultural emissions were 16 billion tons of carbon dioxide equivalent (an increase of 9% since the year 2000) and globally, the 2020 farm gate emission represented nearly half of total agricultural emissions, according to the Food.....»»
Sediment discovery unlocks Australia"s hidden net-zero resource potential
A new method of measuring sediment thickness across Australia's interior offers a cost-effective and straightforward solution for estimating seismic hazard and resource potential while reducing carbon footprint, according to the largest study of its.....»»
Viewpoint: Fossil fuel subsidies cost Canadians a lot more money than the carbon tax
The federal carbon tax increase is now in effect, and will raise gas prices by three cents per liter in most Canadian provinces......»»
Can savanna emerge in the cold high latitudes and altitudes due to ongoing rapid warming?
Recent studies have shown that rising atmospheric CO2 concentrations and consequential warming may compromise the community structure and functioning of the cold tundra ecosystems. However, in addition to carbon uptake, natural vegetation—particula.....»»
Engineers "symphonize" cleaner ammonia production
Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the h.....»»
New satellite dataset sheds light on Earth"s plant growth
Gross Primary Production (GPP), the process through which plants convert carbon dioxide and sunlight into glucose and oxygen, is the Earth's largest carbon flux. Accurate quantification of GPP is crucial for understanding carbon budgets and their imp.....»»
Researchers show depth-dependent responses of soil organic carbon under nitrogen deposition
In a study published in Global Change Biology, scientists from the Institute of Earth Environment and the South China Botanical Garden of the Chinese Academy of Sciences have shed light on understanding the effects of nitrogen addition on soil organi.....»»
New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process
In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The technologies for reducing ou.....»»
New carbon nanotube transistor enhances sensitivity and resolution of molecule glasses
