Brains and nervous systems do a lot of things, but overall their purpose seems to be to allow cells to communicate and behave together. But because gene's generally code for things that help reproduction, you can start to see harsh patterns in behavior.
What is it that makes things alive? What if we made robots that could sustain themselves? What if they could mine metals or recycle old robots, reprogram and remake themselves? There's nothing there we would traditional call alive, but they would have at least have the essence of this perpetual rube Goldberg machine.

The semantics of the model I'm working from use common goods/common property/ common pool resources (resources used by multiple people) and common property regimes (the institutions or social arrangements between people, the property rights regarding common pool resources).

When examining the adolescent brain we find mystery, complexity, frustration, and inspiration. As the brain begins teeming with hormones, the prefrontal cortex, the center of reasoning and impulse control, is still a work in progress. For the first time, scientists can offer an explanation for what parents already know -- adolescence is a time of roiling emotions, and poor judgment.
Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches…the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence? The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. NOVA Wonders looks at how far we’ve come and where machines are headed as their software becomes ever more…cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?
We like to believe we’re in control. But if what we’re discovering about parasites is anything to go by, who is really in control is a lot more complicated, and a lot more interesting, than we ever imagined. So let “The Nature of Things with David Suzuki” help you get over the ick factor, and explore the world of parasites. So let “The Nature of Things with David Suzuki” help you get over the ick factor, and explore the world of parasites. Scientists have collected hundreds of examples of parasites that brainwash their hosts. And now researchers are starting to untangle these parasites’ evolutionary tricks of the trade. In the coastal estuaries of California, Professor Kevin Lafferty of the United States Geological Survey introduces us to a flatworm that lives in three hosts - a snail, a fish and a bird. This parasite’s influence is so profound that it tips the balance of the local ecosystem
Is your smart phone making you stupid? Can you make yourself cleverer? The Great British Intelligence Test measures the brainpower of the nation in one of the largest intelligence experiments of its kind. Devised with leading scientists at Imperial College, London, over 250,000 people around the nation have taken part so far - revealing important new science about the nation’s changing intelligence. Dr Hannah Fry and Michael Mosley put the public to the test, pitting young and old, males and females and tech lovers and readers against each other in a battle of wits. The audience can also play along online at www.bbc.co.uk/intelligencetest The results reveal new science about how our intelligence changes through our life. Which mental abilities peak in our 80s? And when can adults be outsmarted by ten-year-olds? It explores how our gender can affect our intelligence and uncovers groundbreaking new science on how our lifestyle and love of technology is changing our brain. Which of our digital habits are improving our mental abilities and which are harming us?
Through interviews with leading psychologists and scientists, Neurons to Nirvana explores the history of four powerful psychedelic substances (LSD, Psilocybin, MDMA and Ayahuasca) and their previously established medicinal potential. Strictly focusing on the science and medicinal properties of these drugs, Neurons to Nirvana looks into why our society has created such a social and political bias against even allowing research to continue the exploration of any possible positive effects they can present in treating some of today's most challenging afflictions.
