Épisode 34 - Is There Gravity in Space?

5 mars 2013

In a word, "yes" - space is packed with gravity. Hank explains how Isaac Newton described how gravity works, and why even though it seems that things are floating in space, they're still effected by gravity. Every object in the universe is constantly attracting every other object in the universe.

Épisode 35 - The Search for Antimatter

7 mars 2013

If you don't have any idea what antimatter is, you don't have to feel bad - the brightest minds in the world have only recently begun to understand what it is and how it works. Hank gives us the run down on what we know about antimatter, and what we're still trying to figure out.

Épisode 36 - The Manhattan Project

10 mars 2013

Some of the greatest advances in science have come from humanity's more destructive impulses. This is not the fault of science - when we discover powerful truths about the universe it's up to us to decide how to use them because they can either be boons or banes to the world. There may be no better example of this than the work done by the Manhattan Project - the years long, multinational effort to develop an atomic bomb during World War II. The project created unfathomably destructive weapons and led to a 50 year Cold War with the USSR, but is also the source of a lot of information about the atom we didn't have before, which has led to advances in many beneficial fields, like energy production and medicine. Science, like history, is always complicated.

Épisode 37 - Major Brain Dump!

How do their toxins attack the human body with such deadly efficiency? Discover the answers to these and other questions as Hank talks about some of the most deadly natural substances in the world.

Épisode 46 - Anxiety Hurts

26 mars 2013

Everybody knows what anxiety feels like - it's annoying and counterproductive and apparently useless, so why does it exist? It turns out your anxiety isn't useless at all - it's a result of the sympathetic nervous system (in charge of the fight or flight response), which lets you respond immediately to threats and can also help you meet that looming deadline. But you don't want your SNS running the whole show - chronic anxiety not only feels crappy, it damages your cells, alters your brain chemistry, and can exacerbate a wide range of health problems. Hank has the whole story in this episode of SciShow.

Épisode 59 - Patenting Person Parts

20 avril 2013

Since the advent of genetic engineering, a lot of weird questions have cropped up, particularly with regard to what information a company can patent. Individual genes, as they are discovered, are now immediately patented and can be controlled by the company that owns the patent. Do those gene patents encourage science by providing a monetary incentive for researchers? Or do they discourage science by creating artificial barriers to the use and study of genes by the companies that don't hold the patents. Guest host Michael Aranda discusses.

Épisode 60 - SciShow Talk Show #8: Human-Powered Helicopters and a Red Fox

22 avril 2013

Épisode 63 - The Science of Terrorism

27 avril 2013

Science can help create understanding where there is none, but is it possible to study and understand terrorists if we're too busy doing everything we can to stop it? Terrorism is notoriously difficult to study because governments constantly subpoena scientists lists of contacts, making source anonymity impossible. And an outbreak of TB in North Korea is terrible and unnecessary, but it is providing an opportunity for North Korea to, potentially, join the global scientific community.

Épisode 64 - The Times and Troubles of the Scientific Method

29 avril 2013

Science is working tirelessly night and day to disprove its own theories about how the universe works (or at least, that's what science thinks it's doing).

Hank has more details on the marvelous maggot in today's episode of SciShow.

Épisode 71 - THE CICADAS ARE COMING!

11 mai 2013

Cicadas have developed an amazing strategy for growth, survival, reproduction, and overcoming predation by...doing nothing. They do nothing for years (except sip at the juice excreted from root structures) before emerging in huge, simultaneous swarms. The swarm is so huge that predators can't consume even a fraction of it, but so rare that predator populations can't sustain themselves between emergence events. Clever little things!

Épisode 80 - A History of Earth's Climate

27 mai 2013

Earth had a climate long before we showed up and started noticing it and it's influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after we're gone. A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma because the surprising truth is, what we're experiencing now is different than anything this planet has encountered before. So, let's take a stroll down Climate History Lane and see if we can find some answers to a question that's been bugging Hank a lot lately - just how much hot water are we in?

Épisode 81 - Hallucinogens as Medicine

28 mai 2013

Is it possible that, because of the war on drugs, we have demonized a treatment for otherwise untreatable diseases? A way to increase personal well-being, permanently treat depression, break the cycle of addiction, and ease the transition from life into death? The solution to all of these problems (for many people) might be a nice, hallucinogenic trip, but taking that trip can be harder than you might think.

Épisode 82 - Rogue Waves

30 mai 2013

For a long time, rogue waves (defined as waves that are greater than twice the height of surrounding waves) were thought to be a myth, like mermaids or the kraken, but recent developments in satellite imagery and oceanic instruments now show that they occur on a semi-regular basis. But we're still not sure why...

Épisode 89 - Goodall, Fossey & Galdikas: Great Minds

11 juin 2013

Today we know that humans and chimpanzees share 99% of their DNA and that we have a lot in common. Not just how we look, but how we behave, form groups, defend our turf, and love each other. People didn't always see other primates this way, but in the 1960s and '70s, some amazing intrepid women came along to turn primatology on its hairy head. Jane Goodall, Dian Fossey and Birute Galdikas studied chimpanzees, gorillas and orangutans, respectively, and are the very definition of great minds of science. Their contributions to humanity's knowledge about its closest living relatives is the subject of today's SciShow: Great Minds.
