Earth’s Magnetic North Pole Is Shifting South… So What Now?

You may have heard that the earth’s magnetic poles tend to move around. I mean, so do the geographic poles, but magnetic North and South are really mobile…and magnetic North in particular is moving real fast. Like, way faster than we thought it would. And the scientific community is coming up with some really exciting […]

The Race to the Moon’s South Pole Is On, But Who Will Get There First?

The Indian Space Research Organization—or ISRO—announced plans to launch a rover to the moon sometime in July of 2019. Not only will this be India’s first attempt to land on our big gray satellite, the mission is going where no one has gone before: the moon’s south pole. They won’t be alone for long though, […]

Scientists Grew a Lamb in a Bag… Wait What?

I know. This looks pretty freaky, but what you’re looking at is actually a monumental step forward for medicine. Researchers have now created an artificial womb that can successfully keep an extremely premature fetus alive and developing normally. A lamb fetus, that is. The latest development in artificial placenta-based life support technology is an update […]

A New Genetic Alphabet Is Creating Things Nature Has Never Seen

So there are only 4 simple pieces to our genetic code, right? Cytosine, guanine, adenine, and thymine, C, G, A, and T. Well, not anymore folks, not anymore. Now…there are six. When you actually think about it, trying to make an entire complex being and all the crazy stuff that goes with us (gestures at […]

These Liquid-Repelling Materials Defy Nature’s Design, Here’s How

I remember watching this video online and being mesmerized. The more liquid they spilled on the items the more I thought “how was this even working?, what’s going on here?” This is a superhydrophobic coating with properties that are seemingly impossible. But this material science field is making some exciting developments with materials that are […]

This Underground Economy Exists in a Secret Fungi Kingdom

New research has revealed that fungi—you know, like mushrooms—barter and trade with other organisms like little stockbrokers. Basically, there’s a whole economy of nutrients right beneath our feet that we are just uncovering. And yes, it can be pronounced either fun-guy or fun-gee, don’t even start, and their classification has been difficult, to say the […]

Synthetic proteins: Mimicking the molecular machinery of life – Science Nation

[Music] Mile O’Brien: The old saying goes “you can’t beat Mother Nature.” Kent Kirshenbaum: You know, every time we think that we can beat Mother Nature we are humbled over and over again. Mile O’Brien: In cell biology, DNA is usually the star of the show, but DNA’s just a blueprint – a set of […]

What are Chromosomes?

Hi. It’s Mr. Andersen and a lot of my students are confused with chromosomes. And so in this short video we’re going to answer this question. What are chromosomes? And so let’s begin with a pre-quiz. Could you take these four terms, chromosome, base pair, genome and gene, and could you number 1, define them […]

Fundamental Particles

Hi. It’s Mr. Andersen and this is AP Physics essential video 2. It is on fundamental particles which are particles that have no internal structure. So if I were to ask you the following question, this is a sample of pure iron, if I were to say is that a fundamental particle? Hopefully you would […]
