Microbes help harden a mix of sand and gelatin into a living concrete that could interact with people and the environment in great new ways.
Light shining through a water droplet can make more than just a rainbow. A range of other colorful arcs also can develop.
Wild animals carry viruses that can sicken people. Monitoring those viral hosts that pose the greatest risk might help prevent a new pandemic.
Contrails are narrow clouds left behind in the sky by jets. They add to climate change. But a new study suggests a way to curb their contribution.
Need water but you have no access to rain, lakes or groundwater? Materials known as metal-organic frameworks could be used to slurp that water from the air, new data show.
These long-lived woody plants provide shade for people, homes for animals — and help protect the planet against climate change.
By looking at toys washed up on beaches, scientists have estimated how long it takes hard plastics to break down in the oceans. And it’s a long time.
Clothes washed in cooler water and for less time shed less dye and fewer fibers, a new study finds. That’s better for clothes — and the environment.
Composting human bodies yielded good results — and good soil — in one small study. It could become an alternative to burial or cremation in one state.
