Webb rules out thick carbon dioxide atmosphere for rocky exoplanet
Infrared measurements of TRAPPIST-1 c indicate that it is probably not as Venus-like as once imagined......»»
Locally optimized urban form can reduce carbon dioxide emissions
Research suggests that urban areas could reduce their carbon dioxide (CO2) emissions by optimizing their urban form. However, the relationship between urban form and emissions is highly context-dependent and generalizations cannot be made......»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Microbial slime: The ultimate system to understand our planet
Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, and very high concentrations of carbon dioxide in the atmosphere. Yet, under these conditions, biofilms formed and within thes.....»»
Direct synthesis method uses recovered carbon dioxide and hydrogen to produce formic acid
With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are accelerating to utilize hydrogen as a key energy source. To achieve this goal, the technologies for hydrogen storage, transportation, an.....»»
Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of.....»»
The frozen carbon of the northern permafrost is on the move—we estimated by how much
Among the most rapidly changing parts of our planet are the coldest landscapes near the top of the globe, just south of the Arctic. This region is warming two to four times faster than the global average......»»
Kagome superconductor breaks the rules at record-breaking temperatures
Using muon spin rotation at the Swiss Muon Source SmS, researchers at the Paul Scherrer Institute (PSI) have discovered that a quantum phenomenon known as time-reversal symmetry breaking occurs at the surface of the Kagome superconductor RbV3Sb5 at t.....»»
Soil sampling in Houston"s greater Fifth Ward reveals toxic levels of lead in yards, play areas
Houston, like many American cities, has areas with soil contaminated by non-biodegradable and persistent pollutants such as arsenic, lead, nickel and cadmium, known as heavy metals and metalloids. These are both naturally occurring in the atmosphere.....»»
Braving sharks and hordes of urchins, scientists are growing kelp one forest at a time
The weathered UC Davis Marine Laboratory looms in thick fog on the edge of the ocean near Bodega Bay. Inside, an experiment is playing out that gives a badly-needed boost to Northern California's kelp forests—underwater cathedrals of green and gold.....»»
Addigy simplifies compliance for Apple devices with one-click CMMC and DISA STIG benchmarks
For managed service providers (MSPs) and IT administrators working with the Department of Defense or its contractors, staying compliant with cybersecurity rules isn’t just important—it’s essential. Yet, ensuring compliance with standards like t.....»»
Hubble and Webb are the dream team—don"t break them up, researchers say
Many people think of the James Webb Space Telescope as a sort of Hubble 2. They understand that the Hubble Space Telescope (HST) has served us well but is now old and overdue for replacement. NASA seems to agree, as they have not sent a maintenance m.....»»
Ensuring a bright future for diamond electronics and sensors by perfecting the growth process
Researchers are developing new ideas about the best ways to make lab-grown diamonds while minimizing other forms of carbon, such as soot. These diamonds aren't destined for rings and necklaces, though. These are the kinds that are needed for the comp.....»»
Study finds 30% of regions worldwide achieve economic growth while reducing carbon emissions
More and more regions around the globe combine economic growth with reducing carbon emissions, researchers from the Potsdam Institute for Climate Impact Research and the University of Potsdam found......»»
GM really wants you to believe you’re better off without CarPlay
We’re coming up on two years since GM announced its decision to ditch CarPlay on all of its EVs. By all measures, the transition got off to an incredibly rocky start with its 2024 model year cars. The Chevy Blazer EV, for example, suffered from a s.....»»
Portal to the past: Geologist identifies metamorphic rock as a crucial feature of the ancient Earth"s carbon cycle
If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31. During the Proterozoic Eon—2.5 billion years to 543 million years ago—the sun was still a young star, much dimmer than today,.....»»
Artificial intelligence: A double-edged sword for the environment?
As AI technology progresses, the energy demands of training complex AI models have surged, raising widespread concerns about associated carbon emissions. This rapid growth is fueled by global demand across industries and academia, leading to exponent.....»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Rubber plantations increase leaching of dissolved organic carbon in soil, study finds
Rubber planting brings huge economic benefits, but large-scale rubber plantations have a great impact on the ecological environment, especially in terms of the soil's physical and chemical properties......»»
Future space telescopes could be made from thin membranes, unrolled in space to enormous size
Space-based telescopes are remarkable. Their view isn't obscured by the weather in our atmosphere, and so they can capture incredibly detailed images of the heavens. Unfortunately, they are quite limited in mirror size......»»
New research estimates carbon emissions from 22 million stream reaches across the US
Using a sophisticated new modeling approach, researchers at the University of Massachusetts Amherst have estimated carbon dioxide emissions from inland waters to 22 million U.S. lakes, rivers and reservoirs. It marks the first time this approach has.....»»
