Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?

In just over 100 days, a new coronavirus has taken an unprepared world by storm, infiltrating every corner of the globe, sending entire nations into lockdown, killing thousands and infecting countless more. Across the world, governments are scrambling to react, hospitals are struggling to cope and an increasingly anxious public are starting to panic.
The world's media is awash with data, information and misinformation. But what are the facts? What is COVID-19 and why is this strain of coronavirus so dangerous? What happens in our bodies when the virus attacks? How does this compare to previous pandemics? What do all the the numbers really mean, and how can data modelling help us look for an exit strategy? This programme investigates the scientific facts and figures behind the biggest public health crisis in living memory, and explores the latest research from the frontline of the medical and scientific fightback.

The Coronavirus disease 2019 (COVID-19) has spread globally since 2019, resulting in a pandemic. While the majority of cases result in mild symptoms, some progress to pneumonia and multi-organ failure. The deaths per number of diagnosed cases is estimated at between 1% and 5% but varies by age and other health conditions.
In this special on the coronavirus, we're with health staff working on the front-line of the Covid-19 crisis - as well as the scientists, economists and virology experts who can answer the question... Coronavirus: Are We Doing Enough?

Where will loved ones spend their last days? Who will be in the room? What feelings and secrets need to be shared with family before it is too late? Acclaimed filmmakers Rob Epstein and Jeffrey Friedman probe these questions and more in the context of two San Francisco Bay Area medical facilities on the forefront of creating new paradigms for end of life decisions with grace.
Filmed and edited in intimate vérité style, 'End Game' follows visionary medical practitioners who are working on the cutting edge of life and death and are dedicated to changing our thinking about both.

Your brain is like a hungry sponge. It's constantly absorbing information. It thrives when stimulated. Between smartphones and books, and movies, and friends and family, thousands of sensations are constantly going into our heads. But what if it all got cut off?. Imagine being confined to a 10-by-10-foot room in complete isolation. No timekeeping devices, no phones, no books, nothing to write on, no windows. Psychologists say that fewer than three days in a room like this can lead to brain damage. I will be staying in this room for three days.
Michael explores the effects of isolation on the human mind by subjecting himself to a very interesting experiment.

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.
