Happy Fat Tuesday!
On this day, celebrated in many countries with lavish parties and high-fat foods, we’re recognizing the importance of fats in the body.
You’ve probably heard about different types of fat, such as saturated, trans, monounsaturated, omega-3, and omega-6. But fats aren’t just ingredients in food. Along with similar molecules, they fall under the broad term lipids and serve critical roles in the body. Lipids protect your vital organs. They help cells communicate. They launch chemical reactions needed for growth, immune function, and reproduction. They serve as the building blocks of your sex hormones (estrogen and testosterone).
Here we feature five of the hundreds of lipids that are essential to health.

When you think of blood, chances are you think of the color red. But blood actually comes in a variety of colors, including red, blue, green, and purple. This rainbow of colors can be traced to the protein molecules that carry oxygen in the blood. Different proteins produce different colors.

In a previous post, we highlighted two NIGMS-funded winners of the 2018 Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring (PAESMEM ). For January’s National Mentoring Month, we tell you about other awardees: J.K. Haynes, Virginia Shepherd, and Maria da Graça H. Vicente.

Brain injuries, cancer, infections, and wound healing are some of the complex and pressing
health concerns we face today. Understanding the basic science behind these diseases and biological processes is the key to developing new treatments and improving patient outcomes. Physician scientists—medical doctors who also conduct laboratory research—are essential to turning knowledge gained in the lab into innovative treatments, surgical advances, and new diagnostic tools.
In this blog, we highlight the work and impact of three surgeon scientists funded by NIGMS at different stages in their careers: Dr. Nicole Gibran (current grantee), Dr. Rebecca Minter (former grantee), and Dr. Carrie Sims (former grantee). Their work, despite the historical underrepresentation of women in the physician scientist training community, has led to revolutionary surgical treatments, new therapeutics, better screening, and improved quality of life for patients.

You’ve probably heard news stories and other talk about CRISPR. If you’re not a scientist—well, even if you are—it can seem a bit complex. Here’s a brief recap of what it’s all about.
In 1987, scientists noticed weird, repeating sequences of DNA in bacteria. In 2002, the abbreviation CRISPR was coined to describe the genetic oddity. By 2006, it was clear that bacteria use CRISPR to defend themselves against viruses. By 2012, scientists realized that they could modify the bacterial strategy to create a gene-editing tool. Since then, CRISPR has been used in countless laboratory studies to understand basic biology and to study whether it’s possible to correct faulty genes that cause disease. Here’s an illustration of how the technique works.

Job: 4th-year general surgical resident, Morristown Medical Center in New Jersey
Grew up in: Manhattan
When not at work, he’s: Programming, coding, thinking about artificial intelligence, and machine learning
Hobbies: Writing/producing electronic music, weightlifting
Ten years ago, Chris McCulloh planned to enter medical school and fulfill his dream of becoming a surgeon. Instead, just months before he was to start med school, he ended up a patient. A freak accident—slipping on a hardwood floor, flying backwards, and landing neck-first on the edge of a glass coffee table—left him with both legs paralyzed at age 28. Undaunted, he deferred entering medical school for a year, undergoing surgery and spending months in rehab.

McCulloh has since finished medical school and recently completed a 2-year pediatric surgery research fellowship at Nationwide Children’s Hospital in Columbus, Ohio. He is now two-thirds of the way through his surgical residency at the Morristown (New Jersey) Medical Center, thanks to the assistance of a specialized wheelchair that allows him to stand nearly to his 6-foot-3 height and helps him perform five to six surgeries a day.
He’s received plenty of attention for being a surgeon with a disability. Along with several print media stories, he was interviewed in 2013 for CBS’ “The Doctors,” and in 2017, ABC’s “20/20” included McCulloh in an episode on physicians with disabilities. But it’s not the wheelchair that distinguishes McCulloh, says Gail Besner, a pediatric surgeon and researcher who hired McCulloh as a postdoctoral fellow. Rather, it’s his enthusiasm, natural research skills, and exceptional surgical prowess that make him special. Besner sees no reason why he won’t reach his goal of landing a highly competitive pediatric surgical residency. “I think he’s capable of doing anything he puts his mind to,” she says.

NIGMS cares deeply about our future generations of scientists. That’s why we continue to fund educational tools that make science exciting for students with the hope of steering them toward career paths in science. These materials are available to educators for free through the Science Education Partnership Award (SEPA) program.
SEPA funds innovative Science, Technology, Engineering, and Mathematics (STEM ) and Informal Science Education (ISE ) projects for pre-kindergarten through grade 12. By encouraging interactive partnerships between biomedical and clinical researchers and educators, schools, and other interested organizations, SEPA provides opportunities to:
- Motivate students from underserved communities to consider careers in basic or clinical research
- Improve community health literacy
Here are just a few SEPA-funded resources that educators can use to peak their students’ interest in science:
Charles Darwin Synthetic Interview (middle school through grade 9, and general public)

In this free interactive experience for iOS and Android devices, students learn about Charles Darwin, the naturalist, geologist, and leading contributor to the fundamental principles of evolution. Students select from a list of questions to ask a virtual Darwin and receive insight into topics that include:
- His childhood and personal quirks
- His adventures
- Principles of evolution
- Public response to his discovery
Modern-day biologists and other experts provide commentary and answer questions beyond Darwin’s 19th century knowledge. A pay version of the app includes many more questions and answers. Lesson plans and other lessons on evolution are also included with the apps, which were developed by The Partnership in Education at Duquesne University, along with several other SEPA-funded resources.

Six NIGMS grantees are among this year’s winners of the Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring (PAESMEM). The award was established by the White House in 1995. This year, it went to 27 individuals and 14 organizations.
PAESMEM recipients were honored during a 3-day event in Washington, D.C. The event featured a gala presentation ceremony and a White House tour. In addition, each winner received a $10,000 grant from the National Science Foundation, which manages PAESMEM on behalf of the White House Office of Science and Technology Policy.
The event also included the first-ever White House State-Federal STEM Education Summit. During the summit, awardees joined leaders in education and workforce development from across the nation, including U.S. territories and several Native American tribes, to discuss trends and future priorities in STEM education. The discussions will inform the development of the next Federal STEM Education 5-Year Strategic Plan, which must be updated every 5 years according to the America COMPETES Reauthorization Act of 2010.
The six NIGMS-supported PAESMEM winners are listed below. In this blog, we will highlight the work of each one, starting with Ann L. Chester and John A. Pollock.
- Ann L. Chester, Ph.D., West Virginia University
- John K. Haynes, Ph.D., Morehouse College
- John A. Pollock, Ph.D., Duquesne University
- Elba Elisa Serrano, Ph.D., New Mexico State University
- Virginia Shepherd, Ph.D., Vanderbilt University
- Maria da Graça H. Vicente, Ph.D., Louisiana State University
