A team of scientists at the FAMU-FSU College of Engineering and Florida State University’s National High Magnetic Field Laboratory have come up with a new design for a magnetic levitation-based low-gravity simulator that promises a huge increase in vol… Continue reading New low-gravity simulator design promises around 1,000 times the volume→

Cosmic mystery of fast radio bursts deepens with flurry of activity

Posted on by

A huge new dataset could soon help unlock the cosmic mystery of fast radio bursts (FRBs). In the space of a few weeks, over 1,600 new signals were detected coming from one of the most well-studied sources of FRBs, essentially ruling out a leading hypot… Continue reading Cosmic mystery of fast radio bursts deepens with flurry of activity→

Quantum gas free fall experiment creates coldest temperature ever recorded

Posted on by

Physicists in Germany have produced the coldest temperature ever recorded – a chilly 38 trillionths of a degree above absolute zero. The strange experiment involved dropping a quantum gas, and switching a magnetic field on and off to bring its atoms to… Continue reading Quantum gas free fall experiment creates coldest temperature ever recorded→

Bizarre repeating radio signal near galactic center may be brand new object

Posted on by

Astronomers have detected a strange radio source coming from somewhere near the center of the Milky Way galaxy. The signal repeats seemingly at random, and can’t be neatly attributed to any known astronomical object, leading the team to consider that i… Continue reading Bizarre repeating radio signal near galactic center may be brand new object→

Crystal prism provides better control to quantum computer chips

Posted on by

As revolutionary as they could be, quantum computers still have a few kinks to iron out, such as controlling more than a few dozen qubits at once. Now, researchers at the University of New South Wales (UNSW) have found a way to control potentially mill… Continue reading Crystal prism provides better control to quantum computer chips→

Five fast radio bursts tracked to home galaxies

Posted on by

Astronomers are another step closer to solving one of the most intriguing cosmic mysteries of recent times – fast radio bursts (FRBs). A team has now traced five signals to their points of origin within the spiral arms of galaxies, narrowing down the l… Continue reading Five fast radio bursts tracked to home galaxies→
