Paul Andersen explains how natural selection is a major mechanism in evolution. The video begins with a discussion of Charles Darwin and the details of natural selection. The data of the peppered moth during the industrial revolution...

You might think you know why the platypus is a bizarre beast. Maybe you know that it lays eggs, that the males have venomous spurs on their ankles, and that it can sense electricity with its bill. But do you know the most bizarre thing...

How important is it to wear sunscreen when out in the Sun. Find out with this simple experiment!

Mutagenesis is the process of inducing mutations using physical, chemical, or biological mutagens, though mutations can also occur spontaneously during DNA replication. Physical mutagens include ionizing radiation (X-rays, gamma rays)...

Ultraviolet (UV) light acts as a physical mutagen by inducing pyrimidine dimers, especially thymine dimers, which distort DNA structure and hinder transcription and replication. The damage can be repaired by photo reactivation, a process...

It's been three years since NASA's Juno spacecraft arrived at Jupiter. But what has it seen and discovered? We will examine Jupiter's magnetic field, core, bands, aurora, atmosphere, storms and clouds.

Everything you could want to know about Jupiter.

Everything you could want to know about Neptune's largest moon, Triton. NASA Voyager 2 images of Triton explained.

Finding scorpions in the desert at night is surprisingly easy with an ultraviolet torch since scorpions fluoresce under UV light. This phenomenon, where scorpions absorb UV light and re-radiate it as bright neon green, isn't unique to...

The world has already faced a major global climate challenge: the hole in the ozone layer, discovered in 1985. Find out what ozone is, why it's important, and how the ozone hole is being repaired. Earth Science - Human Impacts - Learning...

Why Do Microbes Explode Under UV Light?

Emitting Radiation | Radioactivity | Physics | FuseSchool What do you think of when you hear the phrase “emitting radiation”? Do you think it’s a good thing or a bad thing? What if I told you it was vital for life on Earth? In this video...

It's been three years since NASA's Juno spacecraft arrived at Jupiter. But what has it seen and discovered? We will examine Jupiter's magnetic field, core, bands, aurora, atmosphere, storms and clouds.

UV light can be used to cure a range of materials, from adhesives to coatings to dental materials. At the NIST Combinatorial Methods Center, we have developed tools that allow us to screen a material's response as a function of UV...

Jo Robinson discusses the significant nutritional downgrades in our food since the inception of agriculture, emphasizing the loss of vital nutrients like protein, minerals, vitamins, and particularly antioxidants. She advocates for...

Heme Catabolism (1/2): Eukaryotic Reactions of Heme to Bilirubin
