In this video Paul Andersen explains how a radioactive nuclei can decay by releasing an alpha, beta, or gamma particle. The exact moment of decay for each nuclei can not be determined but probability is useful in predicting the...

3 billion base pairs is a pretty typical genome size for organisms like us, but there are a few plants and animals with genomes so huge they completely blow this number out of the water. Hosted by: Olivia Gordon

This video explains the differences between copper and helium, highlighting their properties as elements. It introduces the concept of elements as chemically pure substances that cannot be further simplified. The video also mentions...

How to deStress with progressive muscle relaxation. In this video I teach you how to do progressive muscle relaxation. Progressive muscle relaxation is a meditation technique used to reduce muscle tension. As you constantly hunch over a...

Near-Earth Objects, or NEO's, cross our planet's orbit on a regular basis, but only a handful are large enough to pose a threat. One of these objects is asteroid 1999 RQ36, a "leftover" from the formation of our solar system...

In this video I tie together the previous three videos of this series so that you can see what a fully conjugated verb looks like in the present tense. I give example sentences for each form of each verb. I chose verbs that illustrate...

When a radioactive atom goes through alpha or beta decay, the atom itself changes into a different element. For example, carbon-14 decays to nitrogen-14 when it emits beta radiation. It’s impossible to predict when an individual atom...

In this video, students learn about radioactive decay and how to solve half-life models. The teacher explains the concepts using examples and equations, demonstrating how to calculate the time it takes for a substance to decay to half...

Can AI help catch oceanic outlaws? From drug smugglers to modern-day pirates, maritime crime fighter Dyhia Belhabib introduces Heva: an AI-powered tool that aggregates international criminal records to detect and stop crime that might...

This video is a quiz over the topics covered in the Earth's Nearest Neighbors series. In this series, we explore the fascinating characteristics of our solar system, focusing on the planets closest to the sun - Mercury, Venus, Earth, and...

This coconut crab was filmed stalking, killing and devouring a red-footed booby. It is the first time these huge crustaceans have been seen actively hunting large, back-boned animals, and suggests they might come to dominate their island...

Katrina Leno talks about how she got the idea to write THE HALF LIFE OF MOLLY PIERCE, out July 8th! You take it for granted. You take for granted going to sleep at night, getting up the next day, and remembering everything that happened...

Humans (and our pets) frequently instinctively stretch as soon as we wake up. But why? What is happening in our bodies when we stretch and yawn to wake ourselves up?

Hurricanes are just made up of clouds and wind moving in a certain pattern…so could we use a nuclear weapon to disrupt that wind enough to stop them?

So the Mars Rovers didn't scoop up any alien lifeforms. Scientist Penelope Boston thinks there's a good chance -- a 25 to 50 percent chance, in fact -- that life might exist on Mars, deep inside the planet's caves. She details how we...

Nuclear power stations produce electricity, which of course is extremely useful. However, they also make radioactive waste. When items have no further use and have radioactivity above certain levels, they are known as radioactive waste....

In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but...

In this video Paul Andersen describes the characteristics of the rate constant in chemical reactions. The rate constant is highly variable in reactions and must be determined experimentally. The rate constant is dependent on both...

Mr. Andersen explains how carbon-14 dating can be used to date ancient material. The half-life of radioactive carbon into nitrogen is also discussed.

In 2005, I watched the British band Keane at the Uptown Theater in Kansas City. After they finished playing a song, the lead singer, Tom Chaplin, said it was the band's first time in Kansas. Many members of the crowd immediately booed...
