“In my lab, we’ve been gene hunters—starting with visible phenotypes, or characteristics, and searching for the responsible genes,” says Miriam Meisler, Ph.D., the Myron Levine Distinguished University Professor at the University of Michigan Medical School in Ann Arbor. During her career, Dr. Meisler has identified the functions of multiple genes and has shown how genetic variants, or mutations, can impact human health.

Becoming a Scientist

Dr. Meisler had a strong interest in science as a child, which she credits to “growing up at the time of Sputnik” and receiving encouragement from her father and excellent science teachers in high school and college. However, when she started her undergraduate studies at Antioch College in Yellow Spring, Ohio, she decided to explore the humanities and social sciences. After 2 years of sociology and anthropology classes, she returned to biomedical science and, at a student swap, symbolically traded her dictionary for a slide rule—a mechanical device used to do calculations that was eventually replaced by the electric calculator.

“As a researcher, you get to learn something new every day, and that knowledge feeds more questions. It’s this eternal learning process, and I find that really enticing about being in science,” says Eszter Boros, Ph.D., an assistant professor of chemistry at Stony Brook University in Stony Brook, New York. Our interview with Dr. Boros highlights her journey of becoming a scientist and her research on biomedical applications of metals.

Q: What drew you to science?

A: I was born and raised in Switzerland, and I went to a linguistics-focused high school there, but I gravitated to chemistry because I loved that we could understand the world at a molecular level and see the macroscopic consequences of microscopic processes.

In Other Words: How Cells Express Themselves

When you encounter the word expression, you may think of a smile, a grimace, or another look on someone’s face. But when biologists talk about expression, they typically mean the process of gene expression—when the information in a gene directs protein synthesis. Proteins are essential for virtually every process in the human body.

Below the title “Expression: In Other Words,” two images are separated by a jagged line. On the left are several cartoon representations of a man with different facial expressions. On the right is a cartoon depiction of DNA and an arrow pointing to a folded protein. Under the images, text reads: Did you know? When biologists talk about expression, they’re typically referring to gene expression, where the information in a gene directs the building of a protein.

“I’m Pink Phoenix, leader of the Vetahumanz League of superheroes, and it’s the best job in the world.” The League of VetaHumanz is a superhero league for veterinarians, founded and led by Pink Phoenix, the alter ego of Sandra San Miguel, D.V.M., Ph.D. Through support from the NIGMS Science Education Partnership Award (SEPA) program, the league seeks to diversify the veterinary profession.

Members of the league work with elementary students across the country to give them a sense of belonging to the veterinary profession. “I’m most proud of bringing people together who share the mission and vision with all their heart,” Pink Phoenix remarks. “Nobody can just be a member of the league. You have to earn the cape.” The league has over 400 certified role models throughout the country who are either veterinarians—VetaHumanz—or veterinary school students—VetaHumanz in training.

Public Alerted to Omicron in New Mexico Through Quick Detection

Over the past 2 years, you’ve probably heard a lot about the spread of SARS-CoV-2—the virus that causes COVID-19—and the emergence of variants. The discovery and tracking of these variants is possible thanks to genomic surveillance, a technique that involves sequencing and analyzing the genomes of SARS-CoV-2 virus particles from many COVID-19 patients. Genomic surveillance has not only shed light on how SARS-CoV-2 has evolved and spread, but it has also helped public health officials decide when to introduce measures to help protect people.

In December 2021, the NIGMS-supported SARS-CoV-2 genomic surveillance program at the University of New Mexico Health Science Center (UNM HSC) in Albuquerque detected the first known case of the Omicron variant in the state, which enabled a rapid public health response. The program’s co-leaders, assistant professors Darrell Dinwiddie, Ph.D., and Daryl Domman, Ph.D., were watching on high alert for it to enter New Mexico, and when it did, they were poised to quickly identify it:
