Can Childhood Stress Affect the Immune System?

Whether it’s growing up in gut-wrenching poverty, dealing with dysfunctional family dynamics, or coping with persistent bullying in school, extreme adversity can shatter a child’s sense of emotional well-being. But does it also place kids at higher of developing heart disease, diabetes, and other chronic health conditions as adults?

Katherine Ehrlich, a researcher at University of Georgia, Athens, wants to take a closer look at this question. She recently received a 2018 NIH Director’s New Innovator Award to study whether acute or chronic psychosocial stress during childhood might sensitize the body’s immune system to behave in ways that damage health, possibly over the course of a lifetime.


A Scientist Who Bends Musical Notes

Posted on by

As a pioneer in cancer immunotherapy, Jim Allison has spent decades tackling major scientific challenges. So it’s interesting that Allison would consider one of the top five moments in his life jamming onstage with country star Willie Nelson. Yes, in addition to being a top-flight scientist at the University of Texas MD Anderson Cancer Center, Houston, Allison plays a mean harmonica.

Allison taught himself how to bend notes on the harmonica as a teenager growing up in a small Texas town. By his 20s, Allison was good enough to jam a couple of nights a week with the now legendary Clay Blaker & the Texas Honky Tonk Band. When Blaker asked if he wanted to hit the road with the band, Allison declined. He had his postdoctoral training to finish in molecular immunology.


From Songbird Science to Salsa Dancing

Erich Jarvis spends his days at the Rockefeller University, New York, studying songbirds and searching for clues about the origins of language. But at least two nights a week, you won’t find this highly accomplished neurobiologist mulling over the latest neuroscience results or shooting an email to colleagues about their ongoing efforts to sequence bird genomes. He’ll be in the dance studio, practicing his latest salsa dancing moves.

In fact, before even considering a career as a scientist, Jarvis was a dancer. He danced ballet in grade school, later enrolling in New York’s High School of the Performing Arts as a dance major. Between academic classes, he spent three hours each day practicing ballet at school and, as a teen, another three hours each night practicing solos and pas de deux at the renowned Joffrey Ballet School and, later, the Alvin Ailey American Dance School. Jarvis even received an invitation as a high school senior to audition for the Alvin Ailey American Dance Theater.


A Scientist and Conservation Photographer

These stunning images of animals were taken by Susan McConnell, whose photographs have appeared in Smithsonian Magazine, National Geographic, Nature’s Best Photography, Africa Geographic, and a number of other publications. But photography is just part of her professional life. McConnell is best known as a developmental neurobiologist at Stanford University, Palo Alto, CA, and an elected member of the U.S. National Academy of Sciences.

How did McConnell find the time while tracing the development of the brain’s biocircuitry to launch a second career as a nature photographer? Her answer: Every research career has its seasons. When McConnell launched her lab in 1989 at the age of 31, she was up to her eyeballs recruiting staff, writing research grants, and pursuing many different leads in her quest to understand how neurons in the brain’s cerebral cortex are produced, differentiated, and then wired together into functional circuits.


From Juggling to Biomechanics

For any aspiring juggler, the path to greatness requires mastering the dreaded “five-club backcross.” It’s a move that begins by juggling five clubs in front of your body and transitions to doing the same thing behind your back! Dr. Noah Cowan has nailed it once, and vows to do it again one day.

But this NIH-funded neuroscientist and bioengineer, who directs the Locomotion in Mechanical and Biological Systems (LIMBS) Laboratory at Johns Hopkins University’s Whiting School of Engineering in Baltimore, doesn’t have much time to practice his juggling these days. Instead, he is focusing on ways to use virtual juggling, such as the ball-and-paddle system shown in the video above, to explore the biomechanics of motion. His ultimate goal?  To apply what he’s learned to advance the fields of robotics, prosthetics development, and physical therapy.
