Discovered almost 100 years ago by Ernest Rutherford, the proton was one of the first particles to be studied in depth. Yet there's still much about it that remains a mystery. Where does its mass and spin come from? What ...

Scientists suggest in a new study the existence of a planetary object called a "synestia," a huge, spinning, donut-shaped mass of hot, vaporized rock, formed as planet-sized objects smash into each other.

Calculating a proton's spin used to be an easy college assignment. In fact, Carl Gagliardi remembers answering that question when he was a physics graduate student in the 1970s. But the real answer turned out not to be simple ...

(Phys.org)—A team of researchers with members from institutions in Germany and Israel has developed a way to launch plasmons with controlled amounts of angular momentum using spiral-like structures fashioned into a smooth ...
Scientists from the University of Granada (UGR) have proven for the first time that there is a close relationship between several emerging phenomena in magnetic systems (greatly studied by condensed matter physicists) and ...

(Phys.org)—A few years ago, physicists showed that it's possible to erase information without using any energy, in contrast to the assumption at the time that erasing information must require energy. Instead, the scientists ...
