What if you could use genetic engineering to stop humanity's most dangerous predator, the deadliest animal on the planet responsible for the death of billions, the mighty mosquito? Along with other diseases, it plays host to Malaria, one of the cruelest parasites on Earth possibly the single biggest killer of humans in history. In 2015 alone hundreds of millions were infected and almost half a million people died. New technology could help us eradicate Malaria forever, but to do so we need to engineer a whole animal population. This is not a hypothetical problem, the modified mosquitoes already exist in a lab.
Should we use the technology, and malaria bad enough to risk it? (Intro Music) Malaria is caused by a group of microorganisms: Plasmodia, very weird microorganisms that consist of just a single cell, they're parasites that completely rely on mosquitoes. Malaria always starts with an insect bite. For up to a month they stay here in stealth mode consuming the cells alive an…

When our vegetarian ancestors started eating meat around two million years ago, it wasn't just because animals taste great, it was pure necessity. From the discovery of fire at the latest, meat became a staple of the human diet. But over the last few years eating meat has increasingly been associated with health risks like heart disease, certain cancers, and early death. So how unhealthy is meat, really?
Dairy products deserve a video of their own. Biologically, we need to eat for three reasons: for energy, to acquire materials to fabricate our cells, and to get special molecules that our bodies can't make themselves. The energy and most of the materials come from the three macronutrients: fats, carbohydrates, and proteins. Proteins are the most important resource for repairing and replenishing our cell structures. The special molecules are a large variety of vitamins and minerals we need to drive metabolic processes. Meat provides us with most of these things. It contains all …

Electricity is all around us all the time.​ It makes our lives easier, safer, more fun,​and most of us never think about it.​ But is there such a thing as too much electricity?​ Could the thing that is the foundation of the modern world​slowly be killing us?​ Before we dive deeper,​let’s try to understand what electricity is,​and how it affects us.​ Electricity is the movement of an electric charge.​ This movement generates ​​Electric​and Magnetic Fields​that spread out through space and carry energy.​
We call this phenomenon:​​​​Electromagnetic Radiation.​​ But, to radiate just means, "giving off".​ Like when the radiator in your house gives off heat​in the form of infrared radiation.​ Different parts of the electromagnetic spectrum​correspond to different types of radiation.​ And, many of them are perfectly harmless.​ Some of them can be dangerous though.​ This is what many people have in mind when they hear the term "radiation".​ The rest of the spectrum covers a…

Humans are proud of a lot of things, from particle accelerators to poetry to Pokémon. All of them made possible because of something humans value extremely highly: Intelligence. We think of intelligence as a trait like height or strength, but when we try to define it, things get fuzzy. In a nutshell, intelligence is a mechanism to solve problems.
Especially the problem of staying alive, which involves finding food and shelter, fighting sexual competitors, or fleeing from predators. Intelligence is not a single thing; it includes the ability to gather knowledge, to learn, be creative, form strategies, or engage in critical thinking. It manifests itself in a huge variety of behaviors. From hardwired or instinct like reactions to different degrees of learning to some sort of awareness. To make this even more complicated, intelligence is also connected to consciousness since awareness is helpful for problem-solving. But we're exploring consciousness in other videos, so today we'll …
