Ring In the New Year With Basic Research

by
0 comments

Empowering basic biomedical research, which focuses on understanding how living systems work, is one of NIGMS’ main goals. This type of research not only helps us learn how our bodies and those of other organisms function but also lays the foundation for advances in disease diagnosis, treatment, and prevention.

We’re excited to see what the upcoming year has in store for the field! In preparation, we’re highlighting what NIGMS-supported scientists had to say in 2023 about the many merits of basic research. Also check out the links to the Biomedical Beat posts that feature them if you haven’t already.

“What’s great about a career in research is that there are so many paths you can take. I get so excited for the future when I think about all the open doors ahead of me,” says Hasset Nurelegne, a senior at Emory University in Atlanta, Georgia. Hasset is majoring in neuroscience and behavioral biology (NBB) as well as English.

Since her first year on campus, Hasset has been an active participant in an NIGMS-funded program at Emory that aims to develop a diverse pool of scientists, the Initiative for Maximizing Student Development (IMSD) (which is now just for graduate students; the Maximizing Access to Research Careers [MARC] program is now available for undergraduates). The Emory IMSD has provided Hasset and other trainees with financial assistance for year-round research experiences and a support system for professional development skills and responsible conduct of research.

Science Snippet: Zooming In on Nanoparticles

Nanoparticles may sound like gadgets from a science fiction movie, but they exist in real life. They’re particles of any material that are less than 100 nanometers (one-billionth of a meter) in all dimensions. Nanoparticles appear in nature, and humans have, mostly unknowingly, used them since ancient times. For example, hair dyeing in ancient Egypt involved lead sulfite nanoparticles, and artisans in the Middle Ages added gold and silver nanoparticles to stained-glass windows. Over the past several decades, researchers have studied nanoparticles for their potential uses in many fields, from computer engineering to biology.

A nanoparticle’s properties can differ significantly from those of larger pieces of the same material. Properties that may change include:

What do antibodies, mucus, and stomach acid have in common? They’re all parts of the immune system!

The immune system is a trained army of cells, tissues, and organs that work together to block, detect, and eliminate harmful insults to your body. It can protect you from invaders like bacteria, viruses, fungi, and parasites.

Innate and Adaptive

The immune system is often thought of as two separate platoons: the innate immune system and the adaptive immune system. Although these two platoons have different jobs and are made up of soldiers with different specialties, they work together to prevent infections.

0 comments

Virginia Commonwealth University’s (VCU’s) Center on Health Disparities and safety and risk management department in Richmond teamed up to develop a series of six lab safety training videos with supplemental funding to their NIGMS-funded Initiative for Maximizing Student Development (IMSD) program. The videos cover topics such as safety culture, biosafety, chemical safety, and emergency response, but what sets them apart is how they showcase diversity and inclusion in the lab.

The first video in the safety training series describes the importance of maintaining positive safety culture, which includes people’s perceptions and attitudes toward safety. This video, along with the other five, is on our NIGMS laboratory safety training and guidelines webpage.

“There aren’t many professions that can provide this much opportunity for learning, especially when it comes to understanding how our bodies work. I really love what I do—I wouldn’t trade it for anything,” says Alan Saghatelian, Ph.D., a professor in the Clayton Foundation Laboratories for Peptide Biology at the Salk Institute for Biological Studies in La Jolla, California. From studying new facts and experimental techniques to adopting new ways of thinking, researchers never stop learning, and Dr. Saghatelian credits his love for learning and exploring as reasons why he’s perfectly suited for science. He’s used these passions to build a successful career in biochemistry.

From Chemistry to Biology

Dr. Saghatelian’s love for chemistry began when he was young. He was drawn to how predictable it could be: Mix two chemical compounds in the same way and they’ll always combine to form the same substance, as dictated by the rules of chemistry.

What Is Antibiotic Resistance?

Bacteria can cause many common illnesses, including strep throat and ear infections. If you’ve ever gone to the doctor for one of these infections, they likely prescribed an antibiotic—a medicine designed to fight bacteria. Because bacteria can also cause life-threatening infections, antibiotics have saved many lives. However, the widespread use of antibiotics has fueled a growing problem: antibiotic resistance.

Antibiotic-resistant bacteria can survive some or even all antibiotics. Other microorganisms, including fungi, can similarly become resistant to the medicines that are used to treat them. Infections from these microorganisms affect many people and are difficult to treat. According to the Centers for Disease Control and Prevention, in the U.S. alone, resistant bacteria and fungi infect 2.8 million people each year, and more than 35,000 die as a result.

Curiosity-Driven Science: Q&A With Saad Bhamla

What do worm blobs and insect pee have to do with human health? We talked to Saad Bhamla, Ph.D., assistant professor of chemical and biomolecular engineering at Georgia Institute of Technology (Georgia Tech) in Atlanta, to find out.

Q: What did your path to becoming a scientist look like?

A: I grew up in Dubai and did my undergraduate work in India, which is where I was first introduced to science. The science faculty members seemed to be having so much fun and would say things like “for the love of science,” but I couldn’t figure out what joy they were getting until I got a taste of it myself—then I was hooked. I like the idea that you can create a legacy doing science because someone can come along 100 years later and build on your work.

After undergrad, I went to Stanford University and earned my Ph.D. in the lab of Gerald Fuller, Ph.D., and then stayed at Stanford for postdoctoral work (postdoc) in the lab of Manu Prakash, Ph.D. In 2017, I joined the faculty at Georgia Tech. On paper, I’m a chemical engineer, but I describe myself as more of a biophysicist.

Pharmacologists research how the body acts on medicines (e.g., absorption, excretion) and how medicines act in the body, as well as how these effects vary from person to person. NIGMS-funded pharmacology researchers are:

  • Conducting research to design medicines with fewer side effects
  • Exploring how genes cause people to respond differently to medicines
  • Developing new methods and molecular targets for drug discovery
  • Discovering medicines based on natural products
  • Understanding how medicines act using computers
  • Monitoring brain function under anesthesia to develop safer anesthetic medicines that reduce side effects
  • Creating artificial tissue to heal muscles after traumatic injuries
  • Investigating how to treat patients with sepsis
  • Measuring tissue damage from burns to help improve treatment options

The NIGMS Science Education Partnership Award (SEPA) program provides opportunities for pre-K-12 students from underserved communities to access STEM educational resources. SEPA grants support innovative, research-based, science education programs, furthering NIGMS’ mission to ensure a strong and diverse biomedical research workforce. SEPA projects generate resources that are mapped to state and national teaching standards for STEM and are rigorously evaluated for effectiveness; most are also available at no cost. These resources include mobile laboratories, interactive health exhibits in museums and science centers, educational resources for students, and professional development for teachers. Projects engage students and encourage them to envision themselves having careers in biomedical research.

To celebrate National STEM Day, we’re taking a look back at some of the SEPA projects we’ve recently featured on the blog, as well as our STEM teaching resources website, which includes several SEPA-funded materials. Check out the snapshots of each of the projects with links to the full articles and the teaching website below.
