"The Fountain of Youth" - An Interview with Chong He of the Buck Institute, Novato

by Shoshana Harlem, Terra Linda High School

Dr. Chong He works at the Buck Institute in Novato. She received a PhD in Chemistry at Peking University. She studies the lifespan of worms and yeasts and solutions in how to improve their lifespan. One of her most recent discoveries was that ibuprofen can help yeasts and worms live a longer life.

1.       What made you want to study diseases and medicine?
My parents are medical doctors. My mom specializes in internal medicine and my dad is a surgeon. Growing up in a medical doctor environment, I became very interested in how the human body works. And that's why I decided to study medicine and aging.

2.       What are the best parts of your job?

The best part of my job is that I can get to find answers to questions that no one else in the world knows how to solve. I get to be the first one in the world who can make discoveries to prove my hypothesis. This makes me feel very special.

3.       What are the worst parts of your job?

There are more failures than successes in scientific research.

4.       How does ibuprofen help create a longer life?


One of my aging animal models is yeast. When I gave yeast ibuprofen, it seems that ibuprofen makes the yeast uptake less nutrition, such as tryptophan, which is an amino acid that can help our body to make more protein. Even though our body needs tryptophan, too much might not be beneficial for longevity.


5.       How can life be extended?

The worm is another animal model commonly used by scientists to study aging. We can measure the health of worms by measuring how fast they can move. The movement decreases during aging. But when we fed worms ibuprofen, we found that ibuprofen can make old worms move faster. This made us think that ibuprofen might extend healthspan.

Want to learn more about Dr. Chong He and aging? Join us on Wednesday, January 31, 2018 at Terra Linda High School from 7:30 PM - 8:30 PM in Room 207!

Bacteria, Botulism, and Beauty

--> By Talya Klinger, MSS Intern
What do foodborne illnesses, neck dystonia treatments, and celebrities’ beauty regimens have in common? Clostridium botulinum, baratii, and other species of Clostridium bacteria produce all of the above and more. These seemingly innocuous, rod-shaped bacteria, commonly found in soil and in the intestinal tracts of fish and mammals, produce one of the most deadly biological substances: botulinum toxin, a neurotoxin that intercepts neurotransmitters and paralyzes muscles in the disease known as botulism. Nonetheless, botulinum toxin isn’t all bad: this chemical not only protects the bacteria from intense heat and high acidity, but it makes for an effective treatment for medical conditions as wide-ranging as muscle spasms, chronic migraines, and, yes, wrinkles. 

Clostridium botulinum and similar bacteria can make their way into the human body in a number of ways. Wounds infected with Clostridium botulinum or spores ingested by infants can lead to …

An Interview With Diara Spain, Ph.D

By Rachael Metzger, MSS Intern

Ocean acidification is an issue becoming apparent in the effects on both sea creatures and humans. Diara Spain, the Associate Professor of Biology at Dominican University, came to Marin Science Seminar to talk to us about her studies in marine invertebrates and the damage ocean acidification is causing them. 

To learn more about Diara Spain and what inspired her studies we conducted an interview:


1. How did you get interested in biology? Is there a time, event, 
or person in your life that inspired you to pursue the study? I've always been interested in biology, really science in general. I grew up in rural North Carolina and as a kid it was expected that you'd spend most of your free time outside playing with your friends and pets.  One thing that sparked my interest in marine organisms were the summer vacations at the undeveloped beaches in North Carolina. 
2. Why did you specifically decide to focus on functional morphology, locomotion in echinode…

Invention in Medicine this Wed. 10/26/16

Marin Science Seminar for Teens & Community Presents Invention in Medicine How Medical Devices get Invented and Go to Market with Art Wallace MD PhD of UCSF & VAMC SF
Wednesday, October 26, 2016 7:30 - 8:30 pm Terra Linda High School, Room 207 320 Nova Albion, San Rafael, CA 94903 


Art Wallace started out in experimental surgery and radiology studying imaging of the heart using CT
scanners. He has worked on a number of devices that originally were built for experimental studies that evolved into clinically useful devices including a cardiac output monitor, the off pump CABG, off pump aneurysm surgery, electronic sedation, and a selective coronary vasodialtor. Dr. Wallace will explain his experiences with the inventive process using examples from both device design and drug development. There will be a brief discussion of the importance of intellectual property, patents, venture capital, FDA approval, and business development in completing the invention process. There will …
