Researchers prove fragments of splitting atomic nuclei begin spinning after scission

Posted by in category: futurism

A large international team of researchers has proven that fragments of splitting atomic nuclei begin spinning after scission occurs during nuclear fission. In their paper published in the journal Nature, the group describes their experiments, which may one day fully explain why such fragments begin spinning in the first place.

Away From Silicon Valley, the Military Is the Ideal Customer

Posted by in categories: drones, military

The Defense Department is hungry for small drones that will track objects and fly into buildings, combat zones and other dangerous areas with little help from remote pilots. Self-piloting drones will become a key part of fighting and other military activities in the years to come, said Mike Brown, director of the Defense Innovation Unit, a Pentagon organization that aims to facilitate cooperation between the military and the tech industry.


While much has been made of tech’s unwillingness to work with the Pentagon, start-ups are still plumbing the industry’s decades-long ties to the military.

A deep learning technique to solve Rubik’s cube and other problems step-by-step

Posted by in category: robotics/AI

Colin G. Johnson, an associate professor at the University of Nottingham, recently developed a deep-learning technique that can learn a so-called “fitness function” from a set of sample solutions to a problem. This technique, presented in a paper published in Wiley’s Expert Systems journal, was initially trained to solve the Rubik’s cube, the popular 3D combination puzzle invented by Hungarian sculptor Ernő Rubik.

Astronomers Think They’ve Found the Neutron Star Remnant Left Behind from Supernova 1987A

Posted by in category: cosmology

A new study of x-ray bursts from a local magnetar confirms the origin of a fast radio burst.


Every now and then there is a burst of radio light in the sky. It lasts for just milliseconds before fading. It’s known as a Fast Radio Burst (FRB), and they are difficult to observe and study. We know they are powerful bursts of energy, but we aren’t entirely sure what causes them.

The more we’ve learned about FRBs, the stranger they appear. Most occur outside our galaxy, but there are a few that seem to originate within the Milky Way. Most seem to appear at random in the sky, but a few of them are repeating FRBs. Some of them even repeat with surprising regularity. Because of this, astronomers generally think they can’t be caused by a cataclysmic event, such as the last radio burst of a neutron star as it collapses into a black hole.

Quantum communication device could create limitless data capacity

Posted by in categories: computing, quantum physics

California researchers discovered a way to leverage an unused property of light to apply the unrestricted nature of the quantum domain to wireless communication, creating a new type of channel with infinite capacity that could make looming data limitations irrelevant.
