This week's question comes from Morning Brief reader Robert, who asks, "Do tornadoes rotate clockwise or counterclockwise?

Key PointsBacteria actively sense their environment and use chemical cues to navigate their world through a process called chemotaxis.Chemotaxis aids ...

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a compact device that can actively control ...

We went outside and I asked him to find the Big Dipper, the easily identifiable pattern of stars that make up a portion of the constellation Ursa Major. I reminded him that we could always see the Big ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes ...

It might be expected that the few drivers out and about had their eyes fully on the road, but drivers actually took their ...

Earth’s gravity has a lot to do with what people think is up and what is down. Things fall down toward the ground, but that direction depends on where you are.

Engineers created a MEMS-tunable twisted bilayer photonic crystal chip that dynamically adjusts twist angle and spacing to ...

A twisted pair of photonic crystals integrated with MEMS can dynamically control the handedness of light on a chip.
