- Physics
Scientists Say: Fusion
Nuclear fusion is the physics that powers the sun and could someday provide abundant clean energy on Earth.
- Tech
Insect-inspired drones work together to 3-D print structures
For the first time, flying drones have 3-D printed structures. In the future, such drones might be able to build in hard-to-reach places.
- Climate
Green energy is cheaper than fossil fuels, a new study finds
Switching over to clean, renewable power — and away from fossil fuels — could save trillions of dollars by 2050, a new study finds.
- Climate
Explainer: What is decarbonization?
Lowering carbon levels in our atmosphere to stabilize the climate may start with switching from fossil fuels to greener energy sources.
- Chemistry
Explainer: All about carbon dioxide
Animals and other life on Earth exhale carbon dioxide, which plants use for photosynthesis. But too much of this gas can perturb Earth’s climate.
- Archaeology
Neandertals were a lot like our human ancestors
From toolmaking to healthcare, new research finds that Neandertals shared many cultural and social similarities with our human ancestors.
- Fossils
Armored dinos may have used tail clubs to bash each other
Broken spikes on a fossil dino’s sides are consistent with the armored beast having received a mighty blow from another ankylosaur’s tail club.
- Science & Society
Let’s learn about why schools should start later
The American Academy of Pediatrics recommends that middle and high schools start no earlier than 8:30 a.m.
- Tech
Underwater cameras get a new power source — sound!
Needing no batteries, a new digital camera can run almost continuously to offer new, deeper insights into the ocean world.
- Physics
Scientists Say: Fission
Nuclear fission is the process of splitting atoms apart to release huge amounts of energy.
- Physics
Explainer: What is friction?
The force of friction always acts to slow things down. It depends on just two factors: the surfaces and how hard they press together.
- Animals
Tiny bumps on polar bear paws help them get traction on snow
Super-small structures on the Arctic animals’ paws might offer extra friction that keeps them from slipping on snow, a new study concludes.
