Microplastics are blowing in the wind
Tiny pieces of plastic are traveling through the air, a new study shows. A remote mountaintop saw just as much plastic deposited per day as falls on downtown Paris.

Remote-controlled nanoparticles could fight cancer — gently
A new type of nanoparticle would keep toxic cancer drugs wrapped up so they won’t poison healthy cells. But a remote signal can unleash this cancer-killing medicine once it reaches a tumor.
- Genetics
Scientists Say: Genealogy
This is the study of someone’s ancestry. It could mean finding out about someone’s family tree or the history of evolution from one species to another.

Bears that eat human ‘junk food’ may hibernate less
Wild black bears snacking on leftovers of sugary, highly processed foods show possible signs of faster cellular wear.

Heat signatures help track down old and still deadly land mines
A new technique for locating land mines uses infrared cameras on drones. The novel technology uses temperature differences to find camouflaged mines before anyone might accidentally step on them.

Paleontologists find the first fossilized egg inside an ancient bird
For the first time, paleontologists have found an unlaid egg inside an ancient bird fossil. That egg may have caused its mother’s death.

Scientists Say: Optogenetics
This technique lets scientists control cell activity with light. The light triggers the cell to become more or less active.
