Squishy robot propelled by ka-pow!
This is not your average robot. It flies through the air, propelled by an explosion in one of its arms. It could prove useful in disaster areas or war zones.
- Fossils
Early dino-era start for modern mammals
Fossils of an extinct group of rodent-sized mammals suggest they were related to modern mammals. These ancient remains push back the origin of mammals by many millions of years.
- Computing
3-D printers are making cars!
3-D printing technology makes it possible to print anything — even a car. A team of engineers designed the Strati and then printed the electric cars at events in Chicago and New York.

Explainer: What is 3-D printing?
A new type of computer printer is already doing a lot more than spraying ink onto paper. Some dispense metal, plastic, food — even cells. In short order, people may be able to manufacture almost anything from their home or office.
- Archaeology
Pyramids’ blocks: Possibly rock ‘n’ rolled
No one knows how the ancient Egyptians moved the big stones needed to build their pyramids. A new study suggests they could have rolled them, by attaching wooden posts to the sides.
- Planets
This moon’s surface slides, just like Earth’s
Europa is one of Jupiter’s giant, icy moons. Scientists say it has plate tectonics, which means its surface is covered by moving, giant slabs.
- Archaeology
Mummies existed before Egypt’s pyramids
Materials from an ancient Egyptian cemetery suggest people were preserving their dead long before the pyramids and pharaohs.
- Climate
Where will lightning strike?
When lightning strikes, the results can be deadly. But nature’s dazzling light show also can provide scientists with insights into when and where the next thunderbolt might strike.

Ebola update: Signs of hope
The deadly outbreak of Ebola in West Africa is the worst the world has ever seen. Scientists are studying the virus that causes it and testing experimental vaccines and treatments to try to save lives.

Early school starts can turn teens into ‘zombies’
Teens face serious consequences when they don’t get enough sleep. Yet most school start times don’t allow a full night’s rest, doctors say. The result: Too many students become ‘walking zombies’.
- Planets
Asteroids: A stepping stone to Mars?
NASA's Asteroid Redirect Mission, designed to capture and move an asteroid, may be a step toward getting to Mars. But not everyone agrees it's the right step.
- Chemistry
New nano-cages snag and hold gases
Molecular traps have been developed to snag and hold noble gases, such as krypton, xenon and radon. These atoms tend to resist arrest. But the new traps might grab onto polluting gases so that they can be recycled for later beneficial uses.
