Catalyst converts CO₂ into high-value industrial chemical at room temperature with record

A research team has developed a highly efficient catalyst that directly converts carbon dioxide—a major contributor to global warming—into high-value industrial 2-propanol. The research was published online in Applied Catalysis B: Environment and Energy.

Long-term study suggests landfill methane emissions are far higher than estimates

Methane is an especially potent greenhouse gas, causing much more warming than carbon dioxide on a unit-for-unit basis—and a new, uniquely long-term study of emissions at a New Jersey landfill suggests that estimates of methane pollution in the U.S. and elsewhere may be dramatica

Climate change contributed to big Canada fires, study says as Trump blames mismanagement

Human-caused climate change doubled the likelihood of the tinderbox weather conditions that sparked Canada's massive summer wildfires and in turn angered U.S. President Donald Trump, according to a study released Thursday.

Black silicon catalyst turns carbon dioxide into methane with sunlight

Carbon dioxide is often viewed as a major contributor to climate change, but it can also become a valuable raw material. If scientists can efficiently convert carbon dioxide into useful fuels using sunlight, it would provide a sustainable way to store solar energy while reducing

Two-qubit entangling gate flags its own errors as detectable photon losses

Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. Typical fixes involve vast amounts of extra hardware

Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use

The explosion of new data centers being proposed and built around the U.S. has increased demand for energy to keep them powered and cooled. The Electric Power Research Institute estimates that data centers could consume up to 9% of U.S. electricity generation annually by 2030, up

It’s good for the planet to scrap a new petrol car and buy electric

Carbon savings from driving EVs are so large that it makes sense to scrap a working petrol car to make the switch O recorte ajuda a contextualizar a pauta dentro de Meio Ambiente.

Siberia's growing methane threat could offset 20% of global methane reduction targets by 2

The Arctic is warming at an accelerating pace. As permafrost thaws across vast areas and wildfires become more frequent, large amounts of methane (CH4) are being released. Together, these changes are reshaping the region's greenhouse gas emissions and further intensifying climate

Wildfire-ravaged habitats could take centuries to recover, environmentalists say

Habitats belonging to snakes and rare moths have been destroyed after the wildfires this summer. O recorte ajuda a contextualizar a pauta dentro de Meio Ambiente.

An ultramassive white dwarf half Earth's size may hold a rare oxygen-neon core

Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The finding is important because the composition of a white dwarf's core determines how it will evolve. A paper outlining this di

Photocatalytic method cleaves strong C–H bonds while preserving weaker C–Si bonds

α-Silyl alcohols are unique organosilicon compounds bearing a silyl group and a hydroxy group on the same carbon atom. Because these compounds serve as precursors to reactive species, such as carbanions and carbon radicals, they are pivotal building blocks for synthesizing pharma

Hidden hormone–habitat relationship revealed in reef fish

In the animal kingdom, only those that adapt to their environment survive. This adaptation takes a wide range of forms, from invisible internal shifts in gene expression to dramatic anatomical changes, such as tadpoles growing legs and transitioning to life on land as frogs.
