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)?

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. 

Think like an evolutionary biologist! Investigate the evidence behind evolution and the mechanisms that drive population change. Explore the dynamic relationships that shape ecosystem structure and stability:

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?

Happy New Year from LabXchange! 💙 Here’s to a new year, a shared purpose, and a global community learning science together. What are you most excited to explore, teach, or build in STEM in 2026?

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 Learn more: https://f.mtr.cool/jzdimxpzpv

🔬 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.

“We are being compelled to rethink what learning is and who the learner is.” —Dr. Bayo Akomolafe, author, philosopher, and educator At LabXchange, this is our mission in action. As the world’s science classroom, we’re opening the door to science for everyone, everywhere. #DigitalLearning #UNESCO
