- High-energy bursts of ultraviolet light can break apart carbon dioxide, yielding oxygen gas. The experiment may mimic what happened on Earth billions of years ago.
- Study finds new link between the body and brain in mice and may help explain how exercise heals.
- Scientists probing a cloud of dust and gas some 26,000 light-years away found a chemical with a structure resembling molecules critical for all life on Earth.
- People use saccharin and other artificial sweeteners to try to stay healthy. A study now suggests such sweeteners might actually cause harm by encouraging the wrong bacteria to grow in our guts.
- 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 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.
- 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.
- 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.
- 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.
- 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.
