Scientists are racing to learn whether microorganisms send more laughing gas (nitrous oxide) — a greenhouse gas with 300 times the warming potential of carbon dioxide — into the atmosphere after wildfires.

Researchers have discovered molecular markers for changes to oils in fingerprints over a seven-day time period — information that could be used to estimate fingerprints’ ages more accurately.

Researchers have shown that nanoplastics can enter liver and lung cells and disrupt multiple metabolic processes, potentially harming the organ and causing adverse health outcomes.

Researchers have developed a simple, fraud-resistant technique to evaluate the recycled content of new plastic products.

The genome of mammals' common ancestor has been computationally reconstructed by researchers, enabling scientists to interpret where and why selective pressures occurred in history.

Researchers have developed a new method, called isotope-resolved chemical mass balance, to identify dust participles using isotopic measurements and help understand the impact of dust plumes on air quality.

A new type of spectrometer has been developed that can sense atmospheric water vapor, methane and nitrous oxide simultaneously.

Researchers report success in developing a catalytic process to enable lignin to be used as a path toward a 100% sustainable aviation fuel.

Researchers have honed in on the genes that control root growth in response to gravity, with the hope of developing a crop that can access resources deeper in the soil.

Drinking two to three cups of coffee a day is linked with a longer lifespan and lower risk of cardiovascular disease compared with avoiding coffee, according to research.
