At 9 years old, Raven Delfina Otero-Symphony wanted to be an astronaut. As a fourth-year statistics student at the University of New Mexico, Albuquerque, she still dreams of working for NASA—but as a statistician. You might be surprised to learn that she spent high school and her first semester of college preparing for a career in music, convinced that science and mathematics weren’t for her.

Strings to Stats

Raven enjoyed and excelled in both STEM and humanities classes as a child. As she got older, her interest in STEM wasn’t encouraged, and she began to believe she “just wasn’t a science person.” She concentrated on music because she felt very supported in that pursuit. She played the viola—a stringed instrument slightly larger and deeper in tone than a violin—and performed in symphonies throughout high school.

Happy almost New Year! Throughout 2021 we spoke to more than two dozen NIGMS-supported researchers for the Biomedical Beat blog. They shared their work, career journeys, experiences with the COVID-19 pandemic, and more. Here, we’re showcasing a few of their outstanding quotes. You can learn more about these scientists by checking out the links to the original blog posts.

“I’m an African American woman from Memphis, Tennessee; you don’t see very many people like me in medicine or in science,” says Dijoia Darden, M.D. She’s working toward becoming an academic physician, which will allow her to treat patients, teach, and conduct research. “I’m hoping that as an academic physician, I can inspire other women, especially women of color, to pursue things they’re passionate about."

A Path to Medicine

Dr. Darden was drawn to science from a young age, inspired by her microbiologist mother. She recalls that her mom often helped her create science fair projects, including one where she grew penicillin-producing bacteria taken from a lemon. Later on, during her high school summer breaks, Dr. Darden worked in a lab that studied how certain genes might contribute to cancer.

Like skin that covers and protects our bodies, membranes surround and protect cells and organelles. Membranes are semi-fluid barriers composed mainly of lipids and proteins. They provide structure; control the import and export of molecules such as ions, nutrients, and toxins; and support cellular communication.

The lipids that compose membranes are primarily phospholipids. (Cholesterol is another lipid often present in membranes that helps regulate their stiffness.) Phospholipids have hydrophilic (water-loving) “heads” and hydrophobic (water-fearing) “tails.” Within the human body, a water-loving environment, they line up so that their tails face one another and their heads point outward. In membranes, this alignment makes a bilayer barrier that is two lipid molecules deep.

“I think having a career in science is really the best way to rechannel the inner child, to remain forever curious about the world,” says Brian Munsky, Ph.D., an associate professor of chemical and biological engineering at Colorado State University, Fort Collins. Check out the highlights of our interview with Dr. Munsky below to learn how his childhood practical jokes led to him running a research group that uses computational and experimental methods to study complex processes inside cells.

For many people, the word pathway may bring to mind stepping stones in a garden or a trail through a forest. But when biologists talk about a pathway, they’re referring to a series of actions among molecules in a cell that leads to a certain product or change within that cell. Pathways maintain balance during walking, control how the eyes’ pupils respond to light, and affect skin’s reaction to changing temperature. They control our bodies’ responses to the world, and errors in them can lead to disease.

Scientists often use research organisms to study life. Examples range from simple organisms like bacteria to more complex ones such as mice. NIGMS funds studies of research organisms to understand biological processes that are common to all organisms, including humans. Errors in these fundamental processes can cause disease, and better understanding of these malfunctions can aid in the development of potential treatments.

Research organisms may also reveal novel biological processes that can lead to important scientific or medical technologies. For example, researchers studying interactions between viruses and bacteria made a discovery that led to the CRISPR (clustered regularly interspaced short palindromic repeats) gene-editing system, which was recognized by the 2020 Nobel Prize in chemistry.

“What makes being a scientist exciting is that I don’t know what I’m going to find tomorrow,” says Akhila Rajan, Ph.D., an assistant professor in the basic sciences division at Fred Hutchinson Cancer Research Center in Seattle, Washington. Dr. Rajan is supported by an NIGMS early stage investigator Maximizing Investigators’ Research Award. These awards provide stable and flexible funding for a program of research that falls within NIGMS’ mission. Check out the highlights of our interview with Dr. Rajan to learn about her research and journey as a scientist.

This time of year, many creepy crawlies take center stage to frighten people of all ages. To celebrate Halloween, we've conjured up a slideshow of fascinating but spooky species that NIGMS-funded scientists study. Some of these creatures drink blood like vampires, while others—frogs, worms, flies, and salamanders—are perfect cauldron ingredients for a witch's brew. Check out the slideshow—if you dare!

Happy National Chemistry Week! In honor of this celebration, we’re showcasing posts that focus on elements crucial for human health and scientific exploration. NIGMS-supported scientists are studying how each of these elements (and many others) can impact human health. Check out the list below to learn more, and let us know what your favorite element is in the comments section!

Helium: An Abundant History and a Shortage Threatening Scientific Tools
Scientists first discovered helium burning on the surface of the sun. Today, liquid helium plays an essential role in supercooling vital scientific and medical equipment, such as magnetic resonance imaging machines that take images of our internal organs. Unfortunately, our complex history with the element has led to a recent shortage that threatens some types of scientific research.
