While almost every planet ever found orbits a star, there are some loners that roam the cosmos entirely on their own. Now astronomers have spotted the smallest of these “rogue planets” ever discovered, which is only the size of Earth or smaller.

Some of the most useful tools are the ones that allow you to grab something. However, what if that "something" is very, very small? Well, that's where a new light-activated micro-gripper could come in – it's said to be the world's smallest.

Researchers may have opened the door to tiny, millimeter-scale soft robots, by developing a robotic caterpillar that can climb slopes and move loads and is powered and controlled purely by external light.

A new study is shedding light on a type of binary star system theorized to transition into a state of hibernation lasting thousands of years following powerful nova explosion events.

Quantum technologies are becoming increasingly difficult to advance without memories able to appropriately store atomic-spin information. To help address this problem, scientists from the University of Warsaw claim to have developed a laser-driven atomic memory.
