Stuff To Blow Your Mind

Humans are creatures of gravity. We’re born into it. Life as we know it evolved to thrive in it. So what’s a gravitational organism to do in the low-gravity and zero-gravity expanses beyond Earth? You can’t bring it with you, but scientists have cooked up a few different schemes to replicate its effects. Join Robert and Joe for a full exploration in this episode of the Stuff to Blow Your Mind podcast.

Numerous mythologies speak to the birth of our universe out of darkness and chaos, but can humans follow in the footsteps of the gods? Can we create a universe in the lab? In this episode of the Stuff to Blow Your Mind podcast, Robert and Joe explore the primordial darkness of multiple cosmologies as well as the theoretical depths of human-created universes and simulated realities.

We’ve all heard charges of cultural appropriation in everything from fashion and music to personal world view, but what’s actually at stake here? What is cultural misappropriation, when does it have negative consequences and how does it fit into our historical and scientific understanding of the human experience? Robert and Christian explore.

Appreciation for the katana cuts across cultures and genres, slicing into the hearts of history buffs, japanophiles, comic book fans and more. But what’s so special about the sword of the Samurai? In this episode of the Stuff to Blow Your Mind, Robert and Christian discuss the science of this most skillful blade, the grisly test for its sharpness and its importance in Japanese culture.

Ticks are, in the words of Pliny the Elder, 'the foulest and nastiest creature that be.' If these blood sucking arachnids and their mite brethren weren’t horrible enough, they’re second only to the mosquito in the risk of blood borne human pathogens. In this episode of Stuff to Blow Your Mind, Robert and Joe discuss ticks, chiggers and the mysterious illnesses associated with the lone star tick -- one of which generates a meat allergy in the host.

In 1960, scientists Nathan Kline and Manfred Clynes envisioned a spacefaring cyborg, technologically augmented to endure the rigors of space travel. The subsequent six decades of space exploration largely ignored this radical suggestion, but the advent of gene editing tools like CRISPR present raise new questions. Might genetic alterations give future astronauts the 'right stuff?' What would the physiology of a genetically-augmented space traveler even look like? Robert and Joe explore in this episode of the Stuff to Blow Your Mind podcast.

It’s easy to think yourself a mere brain within a human body -- a cognitive machine making sense out of all the incoming sense data from outside world. But what if other parts of the body and even objects beyond the body serve a vital role in our cognition? In this episode of the Stuff to Blow Your Mind podcast, Robert and Joe discuss the concept of extended cognition and how it relates to the human condition, number systems, spider webs, octopuses, mantises and even a fictional alien brain monster.

Is human civilization growing less violent? Cognitive scientist Steven Pinker argued the point in his 2011 book 'The Better Angels of Our Nature,' in which he also defined the 'five inner demons' that push us to wrath. Know them -- speak their true names -- and you have the power to undermine their influence. In this episode of Stuff to Blow Your Mind, Robert and Christian explore Pinker's thesis and draw in supporting research and dissenting opinions.

Just as manufacturing automation cuts into human jobs, the prospect of creative artificial intelligence raises the specter of robot writers, robot artists and robot musicians who never sleep and always agree with their patron. But paranoia aside, where will creative machine learning take us? Robert and Christian discuss some possibilities in this episode of the Stuff to Blow Your Mind podcast.

Science enabled humans to ascend out of the darkness and tackle life’s problems with systematic, self-correcting rigidity. Yet, when faced with scientific consensus on climate change and other issues, some citizens, politicians and even scientists dig in their heels and deny the shape of our current understand. Why do some people doubt scientific consensus? What’s wrong in science communication? Robert and Joe attempt to find an answer.
