But the cancer kept coming back, popping up in new places in a malignant game of whack-a-mole. “He’d take different medications,” says his wife, Nancy Boerner, “and these would be effective for a bit. Then we’d try another. The effective period would be shorter and shorter, until they just . . . stopped working.”

To this day, Yeston says, “he is the most successful person I can think of who is really interested in a rising tide that lifts all boats. He is interested in being supportive to everyone around him.” Yoon’s first exposure to photochemistry was at the California Institute of Technology, where he was a graduate student working in the lab of Erick Carreira.

Conservationists estimate that poachers kill about 55 African elephants a day. But while experts believe that only a handful of organizations are running the enterprise, finding the evidence to help prosecute the ringleaders is difficult. DNA sequencing to map family relationships among elephants whose tusks are seized could help build cases against smugglers (Nat.

In 1987, ACS immediate past president George Pimentel launched the outreach event as National Chemistry Day. It was such a success that ACS extended it to a weeklong event starting in 1993. “As a longtime NCW volunteer, I have always enjoyed these amazing community-based activities. This year, despite the pandemic, our volunteers from across the world did a wonderful job, interacting with students, their parents, and others in the community, and showing them the value of chemistry in everyday life,” says ACS president H.

NCW got its start in 1987 when ACS immediate past president George Pimentel launched National Chemistry Day. The event was so successful that ACS renamed it National Chemistry Week in 1993. During this year’s celebration, more than 21,000 people visited the NCW website, and the #NCW and #NationalChemistryWeek hashtags were viewed by more than 35 million people around the world, based on online impressions and interactions.

“We spent a lot of fruitless days trying to figure out the most simple and most clear explanation for changes in copy number,” Bafna says. The old sequencing techniques told scientists that gene amplifications were likely on chromosomes. Bafna and Mischel’s research suggests that ecDNA is likely the dominant way in which many cancers amplify genes.

NCW was started in 1987 as National Chemistry Day by George Pimentel, who was ACS immediate past president at the time. The annual outreach program became so popular that in 1993, National Chemistry Day was renamed National Chemistry Week. “Since its inception, NCW has been an important, exciting, and fun way for chemists to connect and collaborate with others in their communities,” ACS president Bonnie Charpentier says.

On the morning of Mole Day, Oct. 23 (abbreviated as 10/23 on calendars in the US, resembling the 1023 part of Avogadro’s number), a local news crew arrived at Wayne State as volunteers were staking down massive blue tarps—9 by 12 m—with element names, symbols, and atomic numbers painted in white. The crew came to talk with Sue White, a lab manager, and Charlie Fehl, a biochemist, who are both advisers to the American Chemical Society student affiliates group at Wayne State.
