A special issue of the ANS journal Nuclear Technology, published last month, observes the 75th anniversary of the Trinity experiment, the world’s first nuclear explosion, on July 16, 1945, near Alamogordo, N.M. The experiment was a first step toward the conclusion of the Manhattan Project and the end of World War II. The special issue, The Manhattan Project Nuclear Science and Technology Development at Los Alamos: A Special Issue of Nuclear Technology, was sponsored by Los Alamos National Laboratory and curated by Mark Chadwick.

Thanks to LANL, the 23 papers published in the issue are open access, which means that a subscription is not required to read this contribution to the history of science. The issue can be accessed on the journal’s platform, hosted by Taylor & Francis, publisher of ANS’s technical journals.

The American Nuclear Society has selected a group of Black former students known as the Tennessee-85 to receive the inaugural Social Responsibility in the Nuclear Community Award. The 85 former students are receiving the honor in recognition of their bravery and leadership displayed in desegregating an Oak Ridge school in Tennessee in 1955. A co-recipient of the award is the Secretary of Energy for the leadership displayed by the Atomic Energy Commission (now the Department of Energy) in ordering the all-white Oak Ridge public schools to integrate that year. The award will be presented at the upcoming ANS Winter Meeting.

ANS past president (1974–1975) J. Ernest Wilkins Jr. was featured in a recent History.com article highlighting the unsung contributions that Black scientists made to the Manhattan Project.

The world’s first atomic bomb test—code-named Trinity and conducted in New Mexico on July 16, 1945—had an unintended outcome that was only recently discovered.

To protect a treasured ecological species of northern New Mexico, the Los Alamos Field Office (EM-LA) of the Department of Energy’s Office of Environmental Management and its contractor N3B this month began their annual task of modifying legacy waste cleanup activities at Los Alamos National Laboratory ahead of the Mexican spotted owl breeding season.

The U.S. Fish and Wildlife Service (USFWS) listed the owl as a threatened species in 1993, when population numbers were decreasing drastically due to the loss, degradation, and fragmentation of their habitat.

To mark the International Day of Women and Girls in Science, the U.S. Postal Service today issued a commemorative Forever stamp recognizing influential nuclear physicist and professor Chien-Shiung Wu (1912–1997).

A great honor: The stamp was dedicated during a virtual ceremony that can be viewed on the Postal Service Facebook and Twitter pages. USPS official Kristin Seaver was joined for the ceremony by Vincent Yuan, a scientist at Los Alamos National Laboratory and son of the honoree; Jada Yuan, granddaughter of the honoree; and Brian Greene, professor of physics and mathematics at Columbia University. The stamp is available for purchase at Post Office locations nationwide and online.

“I am elated to have my mother honored by USPS on a postage stamp because I believe it goes beyond recognizing her scientific achievements; it also honors the determination and moral qualities that she embodied,” said Vincent Yuan. “It’s even more profound that the recognition comes from America, the country of her naturalization that she loved.”

ANS and the Young Members Group are offering the next installment of the “Spotlight on the National Labs” webinar series, featuring Oak Ridge National Laboratory. The webinar takes place on August 12, starting at 1:30 p.m. (EDT).

Registration for the webinar is required.

On July 16, 1945, the research and development efforts of the nation’s once-secret Manhattan Project were realized when the detonation of the world’s first atomic device occurred in Alamogordo, N.M., more than 200 miles south of Los Alamos, in what was code-named the Trinity Test—a name inspired by the poems of John Donne.

On the 75th anniversary of this landmark event, the Department of Energy’s Office of Environmental Management (EM) is highlighting the cleanup, long-term management, and historical significance of the Manhattan Project sites—Los Alamos, Oak Ridge, Tenn., and Hanford, Wash.—that were conceived, built, and operated in secrecy as they supported weapons development during World War II.
