In this week's news, Hank explains how earthworms are doing nanotechnology for us, Americans will soon be eating genetically modified salmon, the Russians are going back to space, and another reason to drink less soda.

American chestnut trees were all over the US at the end of the 19th century until the fungus wiped most of them out. Scientists have been trying to figure out ways to bring those endangered American chestnuts back to their former glory.

There’s a lot of confusion over what organic means, and food with that label might not be as healthy or environmentally friendly as you think.

Genetically modifying plants and animals is complicated business, but some scientists think this tool could be used to save lives in a variety of ways.

Seedless watermelons are basically the best thing ever. But they’re also a delicious paradox. Seeds are a key part of plant reproduction. So how do you breed a plant that doesn’t make any seeds?

After World War Two, the applications of basic discoveries in biology took off—and became big business. Today, we’ll look at the rise of Big Pharma and GMO foods. We’ll also discuss how life-science technologies fundamentally changed...

By 2050, the world’s population will reach nearly 10 billion, so we’ll need to produce twice as much food. New farming technologies like robot harvesters, drones, sensors, lab-grown meat, and genetically modified crops are helping...

GMO or genetically modified organisms are organisms with their DNA modified, usually by adding new or different DNA from another organism. GM crops are crops that have genes from bacteria. These genes allow the plants to either produce...

GMOs. Vaccines. Death Panels. There are a lot of "beliefs" circulating about a wide variety of health policy issues. Luckily, these are all pretty well researched areas. Thanks to thorough investigations, we can conclude with certainty...

Questions and answers about genetically modified organisms.

Una de las tecnologías actuales más polémicas es la ingeniería genética. ¿Son peligrosos los alimentos transgénicos?

Sí, pero no por las razones que crees. Pero primero ¿qué son los transgén
icos?
Una de las tecnologías...

Alan Kapuler is a man who thinks on big time scales, and across wide geographic spheres of reality. A molecular biologist by training, as a young adult, Kapuler experienced an almost spiritual connection from working with plants. Years...

By now we've hopefully all seen Alien: Covenant. If you haven't, go see it right away! It's awesome, and this has spoilers. After you've seen it, you'll probably have a few questions, just as I did. The main thing that left me...

Alan Kapuler is a well-educated man, both in a formal academic sense, and also from a lifetime of hands-on work as an organic plant breeder: planting, breeding, and cataloging his vast collection of open pollinated seeds.

Has science gone too far? Well, it has created these bizarre creatures. From super buff cows to featherless chickens, these are the creepiest, freakiest animals to ever come out of labs.

This clip looks at some of the beneficial and harmful aspects of transgenic plants.

In this animation, we examine the phrase, "You are what you eat". It's a phrase used around the world and throughout history, but how much scientific truth is there to back this statement up?

Many nations ban them, most people have eaten them, and some actively protest in opposition to their existence, but what exactly is a genetically modified organism, and what are some things that aren't a GMO but are nonetheless often...

This clip looks at some of the beneficial and harmful aspects of transgenic plants.

Plant Reproduction Set: 5. This clip demonstrates two of the most common methods of genetic engineering in plants: biolistic transformation and gene splicing.

In this biology playlist, we've learned so much about DNA and living organisms! Well, so has mankind over the past century, and oh, what we have done with this knowledge! It's pretty incredible when you stop and think about it. Let's go...

Sylvain Charlebois, Dalhousie University, on a study that found most Canadians want GMO products to have labels.

Food policy expert Sylvain Charlebois says while similar laws could come into effect elsewhere, more consumers are getting comfortable with buying food with GMO content
