Many readers shared this report: Antimatter just lost a little more pizazz. Physicists know that for every fundamental particle in nature there is an antiparticle — an evil twin of identical mass but endowed with equal and opposite characteristics like charge and spin. When these twins meet, they obliterate each other, releasing a flash of […]

The CBC reports that “Some parts of the Halifax harbour turned a bright shade of pink on Thursday — for science.” After researchers dumped in 500 litres of safe, water-soluble dye, “boats, drones and underwater robots were then deployed to map the movement of the dye, so researchers can understand where materials spread and how […]

Congress took some steps in that direction last year. The I.R.A. beefed up the Loan Programs Office, the Department of Energy’s in-house bank, and it established a new green lending office within the Environmental Protection Agency. But Congress has put these institutions on a short leash with a limited mandate. This means that the government […]

Mariani breaks down neutrino oscillations using ice cream flavors. “You can imagine that you go to an ice cream shop, and you get your favorite: banana,” Mariani said. “And then you step out, and your ice cream flavor now becomes strawberry. You take another two steps, and the strawberry becomes vanilla. Another three steps, and […]

Comment on this story Comment In the fall of 1932, the fliers began appearing around Macon County, Ala., promising “colored people” special treatment for “bad blood.” “Free Blood Test; Free Treatment, By County Health Department and Government Doctors,” the black-and-white signs said. “YOU MAY FEEL WELL AND STILL HAVE BAD BLOOD. COME AND . . […]

Macon County, Ala., bears a history that seems to run parallel with that of the United States itself. On the one hand it is where in 1881, Booker T. Washington chose to establish what is now the Tuskegee University, educating thousands of future Black leaders and preparing them for economic independence. On the other hand, […]

Struggling with cost overruns, the Department of Energy (DOE) has decided to build the United States’s next great particle physics experiment in two phases, officials told physicists this month. The decision means the megaproject—actually two intertwined efforts called the Long-Baseline Neutrino Facility (LBNF) and the Deep Underground Neutrino Experiment (DUNE)—won’t be completed to its original […]

Many residents of the Pruitt-Igoe housing project and nearby north St. Louis neighborhoods witnessed something strange for a few years in the 1950s and again in the ‘60s. Men in protective suits regularly sprayed a mysterious mist into the air, from the tops of buildings and spouts attached to vehicles driving through the predominantly Black […]
