In the Youtube video galaxy a new star has been born: the ASMR videos. It stands for Autonomous Sensory Meridian Response, and refers to the pleasant feeling that users associate with this type of digital content. The physical reaction also changes significantly from individual to individual and people reportedly experience a pleasant feeling of tingling in the scalp, which can spread to the shoulders and back, and usually be accompanied by a feeling of relaxation and generalised well-being. The intensity of the response can also be very strong, so much so that some have used the word 'braingasm', literally 'brain orgasm' to express the feeling.
It's likely that you've already heard about it, but if not, this is the perfect opportunity to learn more about it. Especially because, for the first time, it seems that the benefits of ASMR videos have been scientifically proven.

Two and a half thousand years ago, the Greek philosopher Socrates worried that the wide use of writing would have a negative impact on people's minds. He said that writing would create forgetfulness, because people will not use their memories. They would trust the external written characters and not remember themselves. In a world with an ever-growing tech industry, Michael Stevens tries to find out what effect technology has on our brains. He finds Technology isn't just changing our lives, it's changing our brains. In his experiments he tests what just 10 days of gaming does to things like our spatial memory.

Autistic minds provide windows into how we all think, feel, and behave. A complete brain science should be able to account for all kinds of minds and brains. As long as some minds remain a mystery, so too will all minds.
Michael Stevens travels to London to meet a blind, autistic savant with astonishing musical abilities, and volunteers to have his brain's function temporarily disrupted at UCLA's Neuromodulation Lab.

The nervous system is fundamentally electric. When we move our arm, it moves because a electric signal has been sent to the muscle that controls it. Now, because the brain is electric, we could also use electricity to record what the brain is doing or bypass it entirely, and control a body. That means that we could restore movement to people who are paralyzed, feel through an artificial hand as if it was our own, and even read people's minds.
Michael Stevens explores how electricity can be used to move cockroaches, control other peoples' limbs and even read peoples' thoughts.

Take a look at the issues that will change the way we live our lives in the future. Hannah Fry delves into the data we have today to provide an evidence-based vision of tomorrow. With the help of science experts Hannah tries to discover whether we could ever live forever or if there will ever be a cure for cancer. She finds out how research into the human brain may one day help with mental health, and if it is possible to ever ditch fossil fuels. Hannah and her guests also discover the future of transport - and when, if ever, we really will see flying cars. She discovers whether a robot will take your job or if, as some believe, we will all one day actually become cyborgs. The programme predicts what the weather will be like and discovers if we are on the verge of another mass extinction. Hannah's tenth prediction is something she - and Horizon - are confident will definitely happen, and that is to expect the unexpected!

Reporter Dr. Graham Phillips examines the effects of meditation in his own life, and the medical evidence of how it affects those who practice it. Can meditation literally make your brain younger?
