Humans have long known that glass bends light. However, it took us awhile to figure out that stacking lenses in a tube would open up a whole new world to science, finally allowing us a peek at the microscopic.

The elements had been listed and carefully arranged before Dmitri Mendeleev. They had even been organized by similar properties before. So why is Mendeelev's periodic table the one that has endured? Lou Serico explains via Ekaaluminium,...

Hank tells us the story of his favorite genius lady scientist and radioactive superhero, Marie Curie.

Paul Andersen introduces the nucleic acids of life; RNA and DNA. He details the history of DNA from Griffith, to Avery, to Hershey and finally to Watson and Crick. He also details the difference between prokaryotic and eukaryotic...

It's the final episode of our History of Science series and we thought it would be good to talk a little about some of the people we couldn't get to and some of the reasons we need to talk about diversity in scientists. Thanks for the...

Sometimes trail blazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again.

Originally discovered by accident, X-rays are now used about 100 million times a year in clinics around the world. How do these magic eyes work? Ge Wang details the history and mechanics of the X-ray machine and CT scanners.

Take some time with us to look back on a few of our episodes about scientists who deserve a little more recognition than they got.

Mr. Andersen shows you how to draw Lewis Dot Diagrams for atoms and simple molecules.

Howcast - GFP is an acronym for Green Fluorescent Protein. Scientists won the Nobel Prize in Chemistry for finding this glowing protein in a jellyfish species. Learn the basics about GFP’s use in observing cells and genes.

Simple advice for keeping a credible lab notebook

After giving an explanation of the Periodic Table, Dr. Boyd explains where he thinks the fictitious metal Vibranium would be located on the Periodic Table if it were a real element. What do you think…where should Vibranium go on the...

What if Vibranium was a real elemental metal, where would it be located on the Periodic Table? Watch Dr. Boyd’s fun and creative take on that question.

Photoelectric effect occurs when electromagnetic radiation above the threshold frequency of the given metallic surface, strikes the surface and releases electrons from it. This happens because light is made of massless particles called...
