“I love that you can change the molecular-level structure of a material, then pull it, bend it, or twist it and see firsthand how the molecular changes you introduced influence its stretchiness or bendiness,” says Frank Leibfarth Ph.D., an associate professor of chemistry at the University of North Carolina (UNC) at Chapel Hill. In an interview, Dr. Leibfarth shares with us his scientific journey, his use of chemistry to tackle challenges in human health and sustainability, and his beliefs on what makes a career in science exciting.

“Our main goal is to get elementary students excited to learn about STEM, and for them to see how beautiful and relevant science can be to communities in eastern Montana,” says Amanda Obery, Ph.D., an assistant professor in elementary education at Central Washington University in Ellensburg, Washington. Dr. Obery co-leads the Authentic Community Engagement in Science (ACES) project with Matt Queen, Ph.D., an assistant professor in biological and physical sciences at Montana State University Billings (MSUB).

Slideshow: Circles of Life

Every year on March 14, many people eat pie in honor of Pi Day. Mathematically speaking, pi (π) is the ratio of a circle’s circumference (the distance around the outside) to its diameter (the length from one side of the circle to the other, straight through the center). That means if you divide the circumference of any circle by its diameter, the solution will always be pi, which is roughly 3.14—hence March 14, or 3/14. But pi is an irrational number, which means that the numbers after the decimal point never end. With the help of computers, mathematicians have determined trillions of digits of pi.

To celebrate Pi Day, check out this slideshow of circular microbes, research organisms, and laboratory tools (while you enjoy your pie, of course!). To explore more scientific photos, videos, and illustrations, visit our image and video gallery.

Scientists who are deaf and hard of hearing (DHH) are underrepresented at all career stages, especially at the Ph.D. level. To address this, the Undergraduate Research Training Initiative for Student Enhancement (U-RISE) training program for undergraduates who are deaf and hard of hearing at the Rochester Institute of Technology (RIT) in Rochester, New York, has committed to lifting barriers and increasing DHH representation in science.

Part of RIT’s National Technical Institute for the Deaf (NTID),
the program is now in its fifth year and prepares undergraduate students who are DHH to enter graduate programs through community-building activities, mentored research training, communication access services like interpretation, and much more. We’ve interviewed two RIT U-RISE students and its director to learn how the program supports its trainees.

“Being a researcher is special because there aren’t many jobs that allow you to spend the majority of your time thinking about the things you find the most interesting in the whole world,” says William Ratcliff, Ph.D., an associate professor of biological sciences and the director of the interdisciplinary graduate program in quantitative biosciences at Georgia Institute of Technology (Georgia Tech) in Atlanta. We talked with Dr. Ratcliff about his career path, research on yeast, and advice to budding scientists.

Q: How did you first become interested in science?

A: My family owns land in Northern California that has been passed down for more than 100 years. When I was a child, my brother and I would spend summers on that land getting lost in the woods. We would really see the forest for its parts: seeing how organisms interacted with one other, tracking stages of development, and listening to birdcalls. My grandmother would identify plants by their scientific names, and we’d discuss their reproduction strategies. We became amateur natural historians during those summers. Perhaps it’s no surprise my brother and I both got Ph.Ds. in biology.
