NIH is now a premium partner with Kahoot! Credit: NIGMS.
We’re excited to announce our new partnership with Kahoot! Although we aren’t new Kahoot! gamers, we’ve recently partnered with them to provide you quizzes from across the National Institutes of Health (NIH) in a single place. “Reaching young people to teach them about biomedical science and inspire them to pursue careers in science is critically important to ensuring a diverse and vibrant biomedical research enterprise,” says NIGMS Director Jon Lorsch, Ph.D. “Our partnership with Kahoot! expands NIH’s STEM offerings, providing educators with free, interactive learning tools to spark student interest in health sciences.”
This August marks 10 years of the blog! Throughout the past decade, we’ve brought you blog posts that explore basic science topics, quiz your knowledge, showcase cool images, and more! Some of our most-read favorites include:
Pharmacology is the study of how molecules, such as medicines, interact with the body. Scientists who study pharmacology are called pharmacologists, and they explore the chemical properties, biological effects, and therapeutic uses of medicines and other molecules. Their work can be broken down into two main areas:
Pharmacokinetics is the study of how the body acts on a medicine, including its processes of absorption, distribution, metabolism, and excretion (ADME).
Pharmacodynamics is the study of how a medicine acts in the body—both on its intended target and throughout all the organs and tissues in the body.
Copper pipes, copper wires, copper…food? Copper is not only a useful metal for conducting electricity, but it’s also an essential element we need in our bodies for a variety of important activities—from metabolizingiron to pigmenting skin.
Copper is required to keep your body going. Enzymes that use copper are called cuproenzymes, and they catalyze a wide range of reactions, including making neurotransmitters and connective tissue. The element is found on the Statue of Liberty’s covering, in wiring and electronics, and in the blue blood of crustaceans. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.
The word organic is often used to talk about fruits and vegetables that have been produced in a specific way, typically without the use of synthetic fertilizers and pesticides. But to chemists, organic refers to carbon-containing compounds that are the basis for all living organisms. Ironically, the chemicals prohibited in the farming of organic produce are usually organic molecules.

Organic chemists study, create, and explore carbon-containing molecules. Most organic molecules contain carbon and hydrogen, but they can also include other elements like nitrogen, oxygen, phosphorus, and more. Organic compounds are all around you, from the phospholipids in your body that make up your cellmembranes and the NSAID pain reliever that might be in your medicine cabinet to the fabric of the shirt you’re wearing.
The element potassium plays a pivotal role in our bodies. It’s found in all our cells, where it regulates their volume and pressure. To do this, our bodies carefully control potassium levels so that the concentration is about 30 times higher inside cells than outside. Potassium works closely with sodium, which regulates the extracellular fluid volume and has a higher concentration outside cells than inside. These concentration differences create an electrochemical gradient, or a membrane potential.
Potassium is the primary regulator of the pressure and volume inside cells, and it’s important for nerve transmission, muscle contraction, and more. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.
The element manganese is essential for human life. It’s aptly named after the Greek word for magic, and some mysteries surrounding its role in the body still exist today—like how our bodies absorb it, if very high or low levels can cause illness, or how it might play a role in certain diseases.
Manganese is necessary for metabolism, bone formation, antioxidation, and many other important functions in the body. The element is found in strong steel, bones and enzymes, and drink cans. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.
“An important part of being in science is being in a community,” says Neil Garg, Ph.D., Distinguished Professor and chair of the department of chemistry and biochemistry at the University of California Los Angeles (UCLA). That philosophy has led him to prioritize mentorship, diversity, and inclusion—while maintaining research excellence—as well as re-envisioning what it means to educate students and the public.
Falling in Love With Chemistry
Science was always a part of Dr. Garg’s childhood. He participated in science fairs as a kid but says he did it for the community and not necessarily for the love of science. “When I look back on those projects, they were always with friends—never by myself,” he says. His parents were both scientists and strongly encouraged him to go into medicine, and although he became a premed major at New York University (NYU), he ultimately chose a different path.
Someone’s hand moving to scroll through this blog post is possible because of a mineral that both gives bones their strength and allows muscles to move: calcium. As the most abundant mineral in our bodies, it’s essential for lots of important functions. It’s found in many foods, medicines, and dietary supplements.
Calcium keeps your bones strong, allows your muscles to move, and is important for many other bodily functions. The element is found in foods, medicines, and the world around us. Credit: Compound Interest CC BY-NC-ND 4.0. Click to enlarge.

Brenda Andrade, Ph.D., assistant professor at California State University, Los Angeles (CSULA), wasn’t sure what she wanted to do when she first started community college. Through a program at her high school, she’d participated in Saturday morning science labs on the CSULA campus, and that introduction to science led her to think about pursuing some sort of scientific degree. She recalls flipping through the course catalog to the list of science classes needed to transfer to a 4-year university, and “naively going down the list and taking them.”
When a professor asked her if she’d thought about doing research, she responded, “What’s research?” That professor introduced her to the transfer program between the community college and nearby CSULA, and he encouraged her to apply to the NIGMS-funded Bridges to the Baccalaureate Research Training Program. When she did, she was accepted and began a summer research internship working in the lab of Linda Tunstad, Ph.D., a successful chemist with a similar background to Dr. Andrade’s. “That experience set my career trajectory,” she says. “I saw people like me, other Latinx people and people from underrepresented groups, doing research and thriving, like Dr. Tunstad. It really motivated me.”

Crustaceans use copper complexes to transport oxygen in their blood, giving it a blue color.
