What Makes You Tick: Circadian Rhythms

source: OxfordSparks     2015年11月9日
How do you know when it's time to wake up or go to sleep? More powerful than any alarm are your circadian rhythms. In this animation we take a look at how these rhythms work and what controls them, inspired by the TeenSleep project being carried out at the University to look at how later start times at school might affect achievement.

How does our body know when it’s time to sleep?
Humans detect light through the eye. Light enters the eye and is focused onto the retina at the back of eye. The retina contains photoreceptive cells that detect light and send this information to the brain, via the optic nerve. The most obvious outcome of this process is the ability to form images; to see. Image-forming vision depends upon rod and cone photoreceptors, which are critical for low light vision and bright light colour vision, respectively. However, it was discovered in 1999 that the circadian system of animals lacking rods and cones could still respond to light. This led to the discovery of a new class of photoreceptive cells: the photo-sensitive retinal ganglion cells (pRGCs), which express the light sensitive pigment melanopsin. These pigments undergo a chemical reaction when they absorb light, which causes the ganglion nerve cells to fire signals to the brain.

These signals from the melanopsin pRGCs feed directly into the Suprachiasmatic Nuclei (SCN). These are cells in the hypothalamus, near the base of the brain, which contains the master circadian clock (or pacemaker). The SCN orchestrates our circadian processes, to make sure that systems throughout our bodies are working together, in time. This system is also involved in controlling our sleep-wake cycle. As the level of light gradually decreases at the start of the night we produce increasing levels of a hormone called melatonin. Melatonin plays a vital role in our day-night cycles, acting as an internal signal of night time.

Why is being exposed to light at the wrong time so bad?
If we are exposed to light at the wrong time, say because we work night shifts, this confuses our system. Light suppresses the production of melatonin, and promotes wakefulness. We delay our sleep and other circadian and sleep-dependent processes. We can work nightshifts for years and our circadian system will not adapt to our new sleep-wake cycle – primarily because we are exposed to natural light during the day, which is far brighter than artificial light sources. This leads to a whole host of problems. Working through the night means we are working when our bodies are craving sleep.

Is it different for teenagers?
The reason we are so interested in sleep during adolescence is because our circadian rhythms change during this period. From the age of 10 until around 21 our circadian rhythms delay. This means that as we go through adolescence and into early adulthood we are naturally more inclined to go to bed later and also to get up later. This is a biological process, and will happen to teenagers regardless of their environment.
Asking an adolescent to get up at 07:00 to start school at 09:00 is akin to asking a 55-year-old to get up at 05:00: this leads adolescence to accumulate a significant amount of sleep deprivation. The circadian drive isn’t optimised for wakefulness and engagement until around 10:00.This means that adolescents are typically starting school at a time when they are feeling the effects of sleep deprivation and when their natural rhythms are not optimised for alertness, and therefore learning. There have been a whole host of studies, mostly from the US showing that a delay in the school start time improves sleep, mood, well-being, alertness and academic outcomes with one study suggesting that a delay in the school start time is more effective than improving the quality of the teaching.

Whilst timing of sleep (and activity) is important, so too is understanding what other factors might affect the quality of your sleep. Not only do adolescents have a natural biological predisposition to staying up later, but the devices they use to communicate and for entertainment may also impact sleep. TV screens, tablets and phones emit light at a level which may interfere with sleep onset, compounding the effects of the naturally occurring circadian delay. A recent study has suggested that teenagers may be particularly susceptible to the effects of light emitting deceives. Students are also dealing with the stress of exams and the pressure to perform well. The TEENSLEEP study aims to address some of these issues by looking at the effect of sleep education and delaying the start time of teaching on sleep quality and academic outcomes.

David Chalmers On The Singularity (1-2)

source: Eidos84     2010年11月13日
The upward spiral of artificial intelligence looks set to produce machines which are cleverer and more powerful than any humans. What happens when machines can themselves create super-intelligent machines? 'The Singularity' is the name science fiction writers gave to this situation. Philosopher David Chalmers discusses the philosophical implications of this very real possibility with Nigel Warburton in this episode of the Philosophy Bites podcast.

Office Playgrounds: Can Freedom Be Programmed?

source: Stanford    2016年8月2日
From the Interactive Media & Games Seminar Series; Sebastian Deterding, Assistant Professor Game Design at Northeastern University looks at how the first new economy, playful design has invaded the working world. Today, the offices of startups, digital agencies, and web companies like Google often look more like playgrounds than work spaces. According to a recent survey in the UK, 80% of managers believe that playful office spaces can motivate employees. On closer look, however, their playfulness often bottoms out in bright colors, round shapes -- and the proverbial slide. This talk asks what it might mean to make work environments truly playful, what effects it has on well-being -- and whether we can make people play.

Rev. Joseph Ellwanger: "Strength for the Struggle" | Talks At Google

source: Talks at Google    2016年8月10日
Talks at Google and the Black Googler Network hosted Civil Rights Movement leader Rev. Joseph Ellwanger and his wife Joyce at Google Chicago. The Ellwangers share inspiring insight into their lifetime of social justice advocacy, much of which is captured in Joe Ellwanger’s book, Strength For The Struggle, a collection of lessons learned from involvement in the Civil Rights Movement in Alabama in the 1960s and later in the peace and justice movement in the Midwest’s inner cities.

Joe’s career spans five decades. He was a minister of St. Paul Lutheran Church, an African-American congregation in Birmingham, Alabama during the height of the Civil Rights Movement and was one of the few white Southern ministers to actively support the Movement. He worked alongside the Rev. Dr. Martin Luther King, Jr. to plan demonstrations in Birmingham, led a 1965 march on Selma in support of voting rights, and later met with President Lyndon Johnson to secure his support for the Voting Rights Act of 1965. Joe continued to work in Birmingham until relocating to Milwaukee, where he served as a minister until 2001.
Today, Joe and Joyce work with a coalition of faith-based groups focused on social justice issues.
The conversation was moderated by Zach Horan and Robin Joseph.

'Hey Bill Nye, Can We Use Giant Magnets to Build a Space Elevator?' #Tue...

Bill Nye answers a question submitted by Nick: is it possible to take two giant magnets and use the repulsion force between the two to lift objects into space?
Do you want to ask Bill a question for a future "Tuesdays with Bill?" Click here to learn how to submit: (http://goo.gl/Joiqzo).

Transcript - Nick: Nick here. I was wondering if it’s possible to take two giant magnets and use the repulsion force between the two to lift objects into space or can we set up stages along the way up and how that attraction and repulsion force send a type of space elevator up to the moon or anywhere we want to go. Let me know what you think.
Bill Nye: Nick. It’s Nick for sure. And it’s magnets to create space elevator. So do I just start talking? We’re ready to go? Nick, Nick, Nick. This is an interesting question. Let me say though starting out we all when you play with magnets and you feel the repulsive force it seems strong. But notice that it acts over a very short distance. Just nominally it goes – it’s not perfect but you can estimate it by saying it goes off as the cube of the distance. So if you have magnets this far apart and you make them twice that far apart they only haven an eighth as much umph. So using a magnet to push things up as high as the atmosphere would take an enormously strong magnet and where would that energy come from? Read Full Transcript Here: http://goo.gl/uAQnVM.
