"Mystery": New particle measurement appears to contradict our understanding of the universe, scientists say
CBSN
After a decade of meticulous measurements, scientists announced Thursday that a fundamental particle -- the W boson -- has a significantly greater mass than theorized, shaking the foundations of our understanding of how the universe works.
Those foundations are grounded by the Standard Model of particle physics, which is the best theory scientists have to describe the most basic building blocks of the universe, and what forces govern them.
The W boson is an electrically charged fundamental particle that governs what is called the weak force, one of the four fundamental forces of nature, and therefore a pillar of the standard model.

Americans are continually encouraged to sock away money in a 401(k) or other retirement plan to ensure a comfortable, if not cushy, life in their later years. Yet about half of all U.S. workers in the private sector lack access to an employer-sponsored retirement plan, a huge obstacle in building enough wealth to retire, a recent study finds.

Washington — Kilmar Abrego Garcia, a Salvadoran man who was mistakenly deported back to his home country and then returned to the U.S. for federal prosecution, may remain in federal custody, after his lawyers and prosecutors sparred over whether he would be deported immediately upon his release while awaiting a criminal trial.
