Capturing carbon with energy-efficient sodium carbonate-nanocarbon hybrid material      (via sciencedaily.com)     Original source 

Carbon capture is a promising approach for mitigating carbon dioxide (CO2) emissions. Different materials have been used to capture CO2 from industrial exhaust gases. Scientists developed hybrid CO2 capture materials containing sodium carbonate and nanocarbon prepared at different temperatures, tested their performance, and identified the optimal calcination temperature condition. They found that the hybrid material exhibits and maintains high CO2 capture capacity for multiple regeneration cycles at a lower temperature, making it cost- and energy-effective.

Ground surface conditions impact speed and distance of leaking natural gas      (via sciencedaily.com)     Original source 

When natural gas leaks from a subsurface pipeline, a ground cover of water/snow saturation, asphalt paving or a combination of these can cause the gas to migrate away from the leak site up to three to four times farther than through dry soil, a new study has found. A research team also found that these surface conditions can impact the speed of the leaked gas, as well, traveling 3.5 times faster than an equivalent leak under dry soil conditions.

Oil and natural gas development in Permian is a key source of ozone pollution in Carlsbad Caverns National Park, study finds      (via sciencedaily.com)     Original source 

New research shows that ozone concentrations at Carlsbad Caverns National Park frequently exceed Environmental Protection Agency health standards, likely due to oil and natural gas development in the Permian Basin and surrounding region.

Local dragonflies expose mercury pollution patterns      (via sciencedaily.com)     Original source 

A new study has unveiled surprising findings about mercury pollution: where it comes from and how it moves through the environment vary significantly depending on the ecosystem. In drier regions, most mercury is deposited through rain and snow. In wetter, forested areas, gaseous mercury from the air sticks to leaves, which then fall and carry the toxin into the ground.

Researchers find that frogs can quickly increase their tolerance to pesticides      (via sciencedaily.com)     Original source 

Although there is a large body of research on pests evolving tolerances for the pesticides meant to destroy them, there have been considerably fewer studies on how non-target animals in these ecosystems may do the same.

Unlocking the mystery of preexisting drug resistance: New study sheds light on cancer evolution      (via sciencedaily.com)     Original source 

The evolution of resistance to diseases, from infectious illnesses to cancers, poses a formidable challenge. Despite the expectation that resistance-conferring mutations would dwindle in the absence of treatment due to a reduced growth rate, preexisting resistance is pervasive across diseases that evolve -- like cancer and pathogens -- defying conventional wisdom.

Loss of oxygen in lakes and oceans a major threat to ecosystems, society, and planet      (via sciencedaily.com)     Original source 

Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.

Building a roadmap to bioengineer plants that produce their own nitrogen fertilizer      (via sciencedaily.com)     Original source 

Nitrogen fertilizers make it possible to feed the world's growing population, but they are also costly adn harm ecosystems. However, a few plants have evolved the ability to acquire their own nitrogen with the help of bacteria, and a new study helps explain how they did it, not once, but multiple times.

Study examines urban forests across the United States      (via sciencedaily.com)     Original source 

Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.

How domestic rabbits become feral in the wild      (via sciencedaily.com)     Original source 

After sequencing the genomes of nearly 300 rabbits from Europe, South America, and Oceania, researchers found that all of them had a mix of feral and domestic DNA. They say this was not what they had expected to find.

Complex impact of large wildfires on ozone layer dynamics      (via sciencedaily.com)     Original source 

In a revelation highlighting the fragile balance of our planet's atmosphere, scientists have uncovered an unexpected link between massive wildfire events and the chemistry of the ozone layer. Using satellite data and numerical modeling, the team discovered that an enormous smoke-charged vortex nearly doubles the southern hemispheric aerosol burden in the middle stratosphere of the Earth and reorders ozone depletion at different heights. This study reveals how wildfires, such as the catastrophic 2019/20 Australian bushfires, impact the stratosphere in previously unseen ways.

High and low tide cause low and high methane fluxes      (via sciencedaily.com)     Original source 

Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the seafloor can be just easily three times as much or as little, depending on the tide, according to a new study.

Unprecedented warming threatens Earth's lakes and their ecosystems      (via sciencedaily.com)     Original source 

Lakes, with their rich biodiversity and important ecological services, face a concerning trend: rapidly increasing temperatures. A recent study by limnologists and climate modelers reveals that if current anthropogenic warming continues until the end of this century, lakes worldwide will likely experience pervasive and unprecedented surface and subsurface warming, far outside the range of what they have encountered before.
