“In high school, one of my teachers encouraged me to take an advanced biology class, and I’m so glad I did,” says Yvon Woappi, Ph.D. “The class opened my eyes to the fact that there were other people who loved nature like I did—they’re called biologists!” Now, Dr. Woappi is an assistant professor of physiology and cellular biophysics at Columbia University in New York City. We talked with him about his early love of nature and the night sky, the support he received from NIGMS training programs, and his research on wound healing.

For most people, the path to becoming a scientist starts in the classroom, where you might be introduced to topics like biology, chemistry, and physics. After high school, some science-loving students choose to follow a path to becoming a doctor or a teacher, but those are just two of the many biomedical scientific careers available. Regardless of what field you’re interested in, here’s a rough guide to the different levels of training that scientists may have.

During his time at Roger Williams University (RWU) in Bristol, Rhode Island, Colton Pelletier built a robot that will help simplify data collection for research projects in the lab he worked in—and others—for years to come. Aiding in Colton’s success in the lab was NIGMS funding through the Institutional Development Award (IDeA) Networks of Biomedical Research Excellence (INBRE) program. INBRE funds statewide networks of higher education in IDeA states such as Rhode Island, which have historically received low levels of NIH funding. The program supports faculty research, mentoring, student participation in research, and research infrastructure by connecting primarily undergraduate institutions with research-intensive universities in the state.

RNA is essential for life as we know it. Among other roles, this molecule helps translate the instructions of DNA into proteins, which perform a vast range of tasks to keep us alive and healthy. In past Biomedical Beat posts, we’ve discussed the basics of RNA and how researchers are using it to develop medicines, vaccines, and tests for certain diseases. This year, in honor of RNA Day on August 1, we’ve created a quiz all about this remarkable molecule. Test your knowledge with the questions below!

“I think there’s a very creative side to science, in figuring out how to approach a problem, which I find really engaging,” says Mia Huang, Ph.D., an associate professor of chemistry at the Scripps Research Institute in La Jolla, California. In an interview, Dr. Huang discussed her shift in interest from medicine to science, her graduate school work on nature-inspired antifreeze molecules, and her lab’s exploration of the roles of sugar-coated proteins in our bodies.

Get to Know Dr. Huang

  • Favorite music genre? EDM
  • Cats or dogs? Dogs—I’m a proud mom to a 15-pound Bernedoodle
  • Rainy or sunny? Sunny
  • What was your childhood dream job? Scientist—I’m living the dream!
  • Favorite hobby? Playing video games
  • Favorite piece of lab safety equipment? Safety goggles
  • A scientist (past or present) you’d like to meet? Gilbert Ashwell and Anatol Morell (accidentally co-discovered the asialoglycoprotein receptor)

What Is a Hormone?

by
0 comments

Hormones are chemical messengers in the body that glands form and release, or secrete, into the bloodstream, where they travel to various organs and tissues to change biological functions. Hormone levels fluctuate during a lifespan and even on a daily basis.

Growth spurts in toddlers or sudden changes in adolescents are directly related to large hormonal shifts during development and puberty. Smaller changes occur throughout each day to help maintain normal bodily functions, such as our sleep-wake cycle known as our circadian rhythm.

“Being a scientist is thrilling, and it’s also tremendously fun,” says Eda Koculi, Ph.D., assistant professor of chemistry and biochemistry at the University of Texas at El Paso (UTEP). “In my opinion, science is the only profession that allows a person to simultaneously express their creativity, quench their intellectual curiosity, and serve society.” We spoke with Dr. Koculi about how she became a researcher, what she’s uncovering about how ribosomes are built and modified, and how she encourages students to pursue scientific careers.

Get to Know Dr. Koculi

  • Coffee or tea? Coffee
  • Favorite music genre? Classical
  • Salty or sweet? Salty
  • Early bird or night owl? Night owl
  • Washing glassware in the lab or dishes in your kitchen? Glassware
  • What was your childhood dream job? A scientist or a teacher—and I have both my dream jobs.
  • Favorite hobby? Hiking
  • Favorite piece of lab safety equipment? Geiger counter
  • Favorite molecule? RNA

Research Organism Superheroes: Hydras

Hydras might look like they’re visitors from outer space, but they’re actually Earth-dwelling animals that can be found in fresh water, like ponds or gentle streams. The body of a hydra consists of a thin tubelike stalk that’s about an inch long with several tentacles extending from one end. Some hydras can grow an armlike extension that eventually pops off the main stem to become a new hydra.

Humans have studied hydras for hundreds of years. Antonie van Leeuwenhoek, one of the earliest known microscopists, first described them in 1703 when he looked at water samples under a microscope. You can see hydras—whose bodies are about the length of a paperclip—without them, but microscopes help researchers see their shape in better detail. Scientists commonly use hydras as research organisms because of their incredible ability to regrow lost body parts after injury through a process called regeneration.

The Third Product of Cell Division: Q&A With Ahna Skop

“Throughout my career, I’ve enjoyed studying topics that no one else seems to care about. I always tell people that I like searching through the scientific garbage bin for inspiration,” says Ahna Skop, Ph.D., a professor of genetics at the University of Wisconsin-Madison. We talked with her about the backyard experiment that helped her gain confidence in her scientific abilities, her career-long pursuit to better understand a detail about cell division that others had written off as unimportant, and her desire to build an accessible scientific community.

Q: How did you first become interested in science?

A: Middle school and high school science fairs had a big impact on me. I would develop my ideas, and with the help of my dad, build the experimental setup I needed to answer the scientific question. One of my experiments studied whether ants preferred to eat salt or sugar, so I poured small piles of both all over the backyard and took daily measurements of the height of the piles to figure out which type was shrinking faster. (Spoiler alert for those of you who might try this at home: They liked both but preferred the sugar to the salt.)
