After the Deluge, Images of Impacts and Resilience in Pájaro, California

Fourteen months ago, a catastrophic flood upended thousands of lives in Pájaro, a small Central California farmworker town filled with immigrants who speak mostly Spanish or Indigenous languages. A relentless series of atmospheric rivers transformed the inviting Pájaro River into a malevolent...

AI can help researchers understand what viruses are up to in the oceans and in your gut

Communities of microbes are difficult to study in a laboratory setting. Many microbes are challenging to cultivate, and their natural environment has many more features influencing their success or failure than scientists can replicate in a lab. So systems biologists like me often sequence all...

This is reflected in the accounts of the Danish transport sector's carbon emissions, with road transport accounting for about 90%. About two-thirds of road emissions come from passenger cars, while the remaining third comes from trucks, buses, and vans. In Denmark, the passenger car is the means...

The ocean produces more oxygen and stores more carbon than any other place on Earth, and is home to the majority of life on our planet. Our climate depends on ocean currents propelled by upwelling from the deep sea. We damage it at our peril.\n\nYet, the International Seabed Authority is...

Discovery may explain why Egyptian pyramids were built along long-lost Ahramat branch of the Nile

Some 31 pyramids in Egypt, including the Giza pyramid complex, may originally have been built along a 64-km-long branch of the river Nile which has long since been buried beneath farmland and desert. The findings, reported in a paper in Communications Earth & Environment, could explain why these...

Experts say coral reef bleaching near record level globally because of 'crazy' ocean heat

More than three-fifths—62.9%—of the world's coral reefs are badly hurting from a bleaching event that began last year and is continuing. That's nearing the record of 65.7% in 2017, when from 2009 to 2017 about one-seventh of the world's coral died, said Derek Manzello, coordinator of...

Floating robots reveal just how much airborne dust fertilizes the Southern Ocean - a key climate 'shock absorber'

Using a fleet of robotic floats, our study published in Nature reveals that windblown dust delivers enough iron to support a third of the Southern Ocean's phytoplankton growth. Knowing this will help us understand how global warming will affect key climate processes phytoplankton are involved...
