This week we’re going underground to explore geotechnical and seismic engineering. We’ll look at how structures connect to the ground and transmit loads through their foundations, and how those foundations need to provide a high bearing...

We've been spending a lot fo time thinking about one vaccine: the COVID vaccine. But vaccines have been around since long before SARS-CoV-2 showed up, so let's learn about some of those other vaccines.

About once every century, a massive star somewhere in our galaxy runs out of fuel. No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova. The...

After many years of quietly changing the world, women are finally receiving recognition for contributions in STEM. Let’s celebrate these 5 groundbreaking women, and their contributions to the field of engineering

The hashtag, so simple and ubiquitous, raises the image from mere photo to a new complex entity.

There are batteries powering so many parts of our everyday lives, so today we’re going to talk about how they work and how we can make them better. We’ll explain how they provide power by discharging ions between a cathode and an anode,...

In our final episode of Crash Course Engineering we are going to take all the tools and ideas we’ve discussed throughout this series and try to imagine where we’re headed. We’re going to explore some of the biggest problems that today’s...

How do cells in your body differentiate into other types of cells? Explore cell specialization featuring stem cells and their role in cell differentiation.

Are mangoes toxic? #shorts #science #SciShow

This week on the SciShow Talk Show Andrij Holian and Paulette Jones talk about the development of a new video game designed for middle school students in order to increase their interest in STEM careers. Then Jessi from Animal Wonders...

50 years ago, humans walked on the moon! Let's celebrate by watching some of our favorite videos about the Apollo missions.

Can we change the blueprints of life? This week we are exploring that question with genetic engineering. We’ll discuss how selective breeding can improve agricultural practices, and the potential DNA-level engineering could have on other...

Paul Andersen explains how organisms regulate timing and control. Phototropism and Photoperiodism allow plants to respond to light throughout the day and year. Circadian rhythms are used in all organisms (including animals) as an...

What if, no matter how strong your password was, a hacker could crack it just as easily as you can type it? In fact, what if all sorts of puzzles we thought were hard turned out to be easy? Mathematicians call this problem P vs. NP, it...

We’re beginning our engineering journey with a tour through the major branches. Today Shini explains the facets of civil engineering, including structural and construction engineering, city planning, transportation, and sanitation.

Every star, black hole, human being, smartphone and atom are all constantly pulling on each other due to one force: gravity. So why don’t we feel pulled in billions of different directions? And is there anywhere in the universe where...

Nuclear weapons are some of the most powerful tools of destruction on Earth, and the full scope of a nuclear detonation is almost unimaginable. However, there is a scientifically supported plan of action that could save thousands of...

Unlike measles, Influenza requires a fresh shot of vaccines every year. But why?

We’ve discussed the four main branches of engineering but there are so many other fields doing important work, so today we’re going to explore a few of them. In this episode we’ll explore some of the history and fundamentals of...

In the 1960s drug-resistant strains of malaria emerged, making the disease even deadlier than before. Then, pharmaceutical scientist Tu Youyou discovered a promising new remedy buried within the pages of ancient Chinese texts.

Not to deter you from eating your vegetables, but what if we told you that certain parts of your salads, like kale, broccoli, and cauliflower were all the same species?

Would a mile-high skyscraper ever be possible? Explore the physics behind some of the tallest buildings and megastructures in the world. -- In 1956, architect Frank Lloyd Wright proposed a mile-high skyscraper, a building five times...

We’ve talked about many important concepts for engineers, but today we’re going to discuss a hugely important one that you might not even realize is an engineering concept: ethics. We’ll talk about what a Code of Ethics is. We’ll explore...

They don’t call water the building block of life for nothing, most living things need it. The palo verde tree, however, has managed to skate by needing it a lot less than the rest of us.
