A cosmic 'speed camera' just revealed the staggering speed of neutron star jets in a world first

How fast can a neutron star drive powerful jets into space? The answer, it turns out, is about one-third the speed of light, as our team has just revealed in a new study published in Nature.

Saturday Citations: 100-year-old milk, hot qubits and another banger from the Event Horizon Telescope project

Is the milk sold today similar to the milk available 100 years ago? Here, drink this and give me your results. Also, physicists achieve superconductivity at a temperature slightly higher than 0 degrees Kelvin and slightly ...

'Shear sound waves' provide the magic for linking ultrasound and magnetic waves

A team led by researchers from the RIKEN Center for Emergent Matter Science in Japan has succeeded in creating a strong coupling between two forms of waves—magnons and phonons—in a thin film. Importantly, they achieved ...

Sawfish are spinning, and dying, in Florida waters as rescue effort begins

Endangered smalltooth sawfish, marine creatures virtually unchanged for millions of years, are exhibiting erratic spinning behavior and dying in unusual numbers in Florida waters. Federal and state wildlife agencies are beginning ...

Magnetic avalanche triggered by quantum effects: 'Barkhausen noise' detected for first time

Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not ...

Quantum computing just got hotter: One degree above absolute zero

For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or –273.15°C). That's because the quantum phenomena that ...
