Science needs her: The researcher.

Dr. Siobhan McRee is a molecular and cellular biologist working in preclinical drug research, developing cellular models to test potential therapies for cancer and rare diseases. Her work contributes to the critical early stages of drug development.

Science needs her: The mentor.

Thembelihle Mnguni is an engineering mentor in Gauteng, South Africa, working to bridge the skills gap for teenagers interested in STEM careers.

Science needs her. Not only in classrooms and labs, but in the systems shaping our future. Today, on the International Day of Women and Girls in Science, we reflect on this year’s theme: “Synergizing AI, Social Science, STEM and Finance: Building Inclusive Futures for Women and Girls.”

Why do mitochondria and chloroplasts have their own DNA? This video explores the endosymbiosis theory: The idea that some of the organelles inside eukaryotic cells began as free-living prokaryotes that formed long-term symbiotic relationships with other cells.

Why can’t cells just keep getting bigger? As a cell grows, its volume increases faster than its surface area. That imbalance makes it harder to move materials in and out of the cell and slows down the reactions happening inside.

What does it actually look like when a cell responds to its environment?
February 5, 2026 at 4:52 PM
Cells are dynamic systems where structure, transport, and energy work together to keep life going. This Cell Structure and Function pathway explores how organelles interact, how materials move through the cell, and how cells maintain an internal environment.

ICYMI: What’s new on LabXchange? Last month, we added new and exciting biology resources, from AP Biology simulations to middle school life science explainers and genetics tools. Here’s what’s new 👇

How can we determine whether a population is evolving over time? Just because variation exists in a population doesn’t guarantee that evolution is occurring.

Why are fossils such a big deal? Fossils are key pieces of evidence for evolutionary change over time.

The fossil record shows the history of life on Earth, from some of the earliest prokaryotes to the origins of humans.

Dogs, farm animals, and even the foods we eat are shaped by artificial selection. Instead of the environment selecting traits, humans choose which plants and animals reproduce—favoring traits like friendliness, usefulness, taste, or yield.

What is bioinformatics and why do scientists use tools like the Basic Local Alignment Search Tool (BLAST)?
January 20, 2026 at 5:05 PM
How do fossils form? Fossils are created when plants or animals are buried by sediment and preserved over long periods of time. In some cases, minerals replace the original material, turning bones, shells, or wood into stone.

Look closely at these finch beaks. Each shape reflects generations of survival in different environments—where food sources, competition, and climate shaped who thrived and who didn’t.

What kind of food do you think each beak is best suited for?

At LabXchange, we believe that the STEMM, education, and workforce communities are all connected–but too often, we work in isolation.

How do scientists uncover the truth? They follow the scientific method: 
1️⃣ Make an observation
2️⃣ Ask a question
3️⃣ Generate a hypothesis
4️⃣ Conduct an experiment
5️⃣ Analyze data & draw conclusions

🔬 We get it: #LabRules can feel repetitive or even boring compared to the excitement of experiments. But the moment you step into a lab without supervision, you quickly realize why they matter. Even a “small” mistake, like misusing equipment, can lead to serious accidents.
