Tracking explosions with toughened-up tracers

What happens in an explosion? Where do the products of that explosion go following the blast? These questions are often difficult to solve. New rugged tracer particles, developed by Pacific Northwest National Laboratory (PNNL) ...

How imperfections can actually improve alloys

Sometimes, in creating an alloy out of multiple metals, defects and structural instability can occur in the material. Now, researchers at the University of Pittsburgh Swanson School of Engineering are harnessing those imperfections ...

Machine learning takes hold in nuclear physics

Scientists have begun turning to new tools offered by machine learning to help save time and money. In the past several years, nuclear physics has seen a flurry of machine learning projects come online, with many papers published ...

NASA to deflect asteroid in key test of planetary defense

NASA will on Monday attempt a feat humanity has never before accomplished: deliberately smacking a spacecraft into an asteroid to slightly deflect its orbit, in a key test of our ability to stop cosmic objects from devastating ...

Examining the origins of proton spin

Where does the proton get its spin? This question has puzzled physicists ever since experiments in the 1980s revealed that a proton's constituent quarks—the most fundamental building blocks of atomic nuclei—account for ...
