Anesthesia is a treatment that prevents patients from feeling pain during procedures like surgery, medical tests, and dental work. Anesthesiologists are doctors who have been specifically trained to give medicines used for anesthesia, which are called anesthetics.
Depending on the procedure they’re having, patients receive different types of anesthesia:

“It’s a thrill to make a discovery in science. In that moment, you’re the only one who knows about this new finding. Then you get to share that discovery with the world,” says Chelsey Spriggs, Ph.D. Dr. Spriggs is an assistant professor of cell and developmental biology at the University of Michigan (UMich) in Ann Arbor. We spoke with Dr. Spriggs about her early introduction to science through school science fairs, current research on viruses, and efforts to broaden participation in microbiology research across the world.
Haley Bridgewater, a graduate student at Boise State University in Idaho, is sure she wants to continue studying infectious diseases after she graduates with her Ph.D., but she’s finding it difficult to choose a specific topic within that branch of biomedical science. “My problem is that I like them all. The more I look into specific research topics to narrow down my options, the longer my list of potential topics grows,” she says.
Haley’s early introduction to science wasn’t related to the biological sciences at all. She grew up in Los Alamos, New Mexico, where her dad studied nuclear chemistry. Discussions about chemistry, physics, and rockets surrounded her, and she would often stare up at the night sky to catch a glimpse of a meteor shower or the International Space Station passing by. But she was even more curious about what was below her feet: What makes an insect different from a rock? What does the microscopic world look like? She received a microscope one year for her birthday and carried it with her everywhere so she could try to answer these questions.
Global Experiences
Haley took an advanced biology class in high school, where she learned not only about the living world, but also the many exciting scientific careers available, such as becoming a researcher. She moved to Tacoma, Washington, and earned a bachelor’s degree from Pacific Lutheran University (PLU), where she majored in biology and global religion.

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!

Sepsis is a condition that can occur when a person’s immune system responds inappropriately to an insult, such as an infection or injury. This condition occurs unpredictably and can be life threatening. Of the 1.7 million adults in the U.S. who develop sepsis every year, at least 350,000 die as a result.
“I think it’s really an exciting time for science. Some people might think that everything out there to be discovered has already been discovered, but that’s far from the truth. There is still much, much more to discover,” says John Jimah, Ph.D., an assistant professor of molecular biology at Princeton University in Princeton, New Jersey. We talked with him about how he moved internationally to pursue his career, how his current research on cell membranes could help treat malaria, and how science holds space for everyone.
Have you wondered what controls the most basic functions of our bodies, like breathing, moving, and sleeping? Chemicals called neurotransmitters play a central role. Neurotransmitters pass messages from one nerve cell to another, and sometimes to muscles or glands. These messages may:
Relationships are complicated, even in nature. Two unrelated species living close together and interacting for survival is called symbiosis. There are three types of symbiotic relationships: mutualism, commensalism, and parasitism.
In a mutualistic relationship, both organisms benefit from the interaction. One example is the relationship between honeybees and flowers. Honeybees drink nectar from flowers, collecting and carrying pollen as they fly from one flower to another. Nectar allows bees to make honey, and spreading pollen helps flowers reproduce. Another example of a mutualistic relationship is between clownfish and sea anemones. The sea anemone provides protection and shelter, while clownfish waste provides the sea anemone with nutrients.

“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.
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!
