Hawk moths hover while they feed, but they recover surprisingly quickly when knocked off-balance. Scientists use high-speed video and mini-cannons made of plastic toy parts to understand how hawk moths respond to disturbances mid-air."Lens of Time: The Art of Staying Stable" was first published on bioGraphic © 2018 California Academy of Science.
The answer lies in the tiny shifts we see in a star's position as Earth revolves around the sun.
When it comes to the unsustainable development of the American coastline, New Jersey owns the honor of being the first and worst. But one town in the state is experimenting with moving a cluster of people out of harm’s way and turning the newly open land into a flood buffer to protect the rest of the community.Read the full story to learn more: "Surrendering to Rising Seas"

Earthquake-warning systems save lives by detecting the first signs of shaking.
For a robot to help scientists truly understand marine life it must engage underwater environments without disturbing them. Massachusetts Institute of Technology researchers report in Science Robotics this week their agile, undulating soft robotic fish does just that, having observed and recorded aquatic life along coral reefs in the Pacific Ocean at depths of up to 18 meters. A product of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), the robot exchanges information with human divers via an acoustic communication modem and propels itself using a motor-powered water pump rather than more disruptive and less agile water jets or propellers that chase away the fish researchers want to study.
These stretchy skins help robots move across rough surfaces, and potentially promote exploration and environmental monitoring.
