...three basic particles of antimatter—positron, antiproton and antineutron—share the same masses and magnitudes of charge as those of their counterparts in matter—electron, proton and neutron, but with opposite charges. Just as a proton and electron compose a hydrogen atom, an antiproton and positron make an antihydrogen atom. When matter and antimatter particles collide, they destroy each other in a burst of energy...
...researchers looked at how changes from a one-tiered and two-tiered formulary insurance plan to a three-tiered formulary at two companies affected employees’ spending on and use of medication. In particular, the researchers focused on the use of proton-pump inhibitors, which treat heartburn; ACE inhibitors, which treat high blood pressure; and statins, which lower cholesterol...
Although a number of people merely switched to lower-cost drugs when the three-tiered plans were put in place, the researchers found that some patients stopped taking their medicines. And while users of proton-pump inhibitors are not supposed to stay on the medications permanently, Frank said, ACE inhibitors and statins are meant for long-term...
Born in Albany, Rosenbluth received his bachelor’s degree from Harvard as a teenager, graduating Phi Beta Kappa. He went on to receive his doctorate from the University of Chicago in 1949. Soon after, he discovered the Rosenbluth formula for proton electron scattering, which is today a central theory of college-level physics. For this development, he later won the Ernest Orlando Lawrence Award...
...Gabrielse team, which goes by the name of Antihydrogen Trapment Collaboration (ATRAP), was able to create an atom of anti-hydrogen, the anti-matter counterpart of hydrogen, by joining an antiproton, the counterpart of a proton, and a positron, the counterpart of an electron. Except for their charges, both the anti-proton and the positron are identical in nearly all respects to their antimatter counterparts...
