Unique fossil: Seeds sprouting from an amber-encased pine cone
New research has uncovered the first fossil evidence of a rare botanical condition known as precocious germination in which seeds sprout before leaving the...
Making solar energy even more sustainable with light-powered technology
Scientists have identified a new process using coordination materials that can accelerate the use of low-cost, Earth-abundant materials with the potential to transform the...
Climate changed abruptly at tipping points in past
Climate scientists identify abrupt transitions in climate records that may have been caused by the climate system crossing a tipping point. They devised a...
Air pollution decrease in India during COVID-19 lockdown not as high as originally thought
Observational data shows air pollution in India decreased drastically in the first COVID-19 lockdown when emissions from vehicles naturally declined, but researchers say those...
Electronic nose on a drone sniffs out wastewater treatment plant stink
Researchers have engineered a portable electronic nose (e-nose) that's almost as sharp as a human nose at sniffing out the stink of wastewater treatment...
Alluring larvae: Competition to attract fish drives species diversity among freshwater mussels
North America's freshwater mussels are both impressively diverse and highly imperiled. Nearly 300 species occur in the United States and Canada, and up to...
Pollutant emissions in major seaports likely to have spiked during the COVID-19 pandemic, study...
Researchers have modeled that pollutant emissions from the shipping sector increased significantly in major international seaports during the COVID-19 pandemic.
A new approach to identify mammals good at learning sounds
Why are some animals good at learning sounds? Did this skill appear when animals started 'faking' their body size by lowering calls? In a...
Market forces halved methane emissions from Uinta Basin oil and gas wells; but that’s...
Since 2015, researchers have been tracking emissions from oil and gas wells and report that, over that time, emissions from the region have fallen...
Solar energy with an’ ironclad future’
Solar energy plays an important role in the fight against climate change as a substitute for fossil fuels. Dye-sensitized solar cells promise to be...
