Buried in this wonderful feature in New Yorker about how most of us have been short on sleep since childhood, suffering “a kind of constant jet lag—and one that is exacerbated by sleeping in on the weekends,” this interesting idea: maybe part of the reason we're seeing so many ADHD diagnoses in young people now is they're all sleep-deprived.
Polyphasic sleep is a method of training your body to requiring much less sleep by taking multiple short naps throughout the day instead of one long sleeping time at night. Over at Quartz, science-trained journalist Akshat Rathi reports on his year-long experiment attempting to "cheat sleep." Read the rest

In my friend Ronni Thomas's latest short documentary, meet parapsychologist Dr. Stanley Krippner, who in the 1960s ran the sleep lab at Brooklyn's Maimonides Hospital where he tested whether sleeping subjects could experience a form of dream telepathy.
Krippner is loved by paranormal researchers, believers, and skeptics alike. He's been honored with lifetime achievement awards from the mainstream American Psychological Association yet ESP researcher Charles Tart says "Stan belongs on the Mount Rushmore of parapsychology. Krippner famously conducted experiments with Timothy Leary and the Grateful Dead. In fact, in 1971, he enlisted the help of the Dead's audience in trying to mentally transmit an image to a sleeping psychic 45 miles away. Irvin Child, the late former chair of Yale's psychology department, wrote in the American Psychologist journal that he believed "many psychologists would, like myself, consider the ESP hypothesis to merit serious consideration and continued research if they read the Maimonides reports for themselves." Krippner's career is mind-bendingly weird and amazing.
Do you have experience with sleep paralysis? Many scientists believe that sleep paralysis is the biological answer to such mysteries as spirit visitations, alien abductions, incubi/succubi, and out-of-body experiences. My old friend Rodney Ascher, director of the excellent film Room 237 and other movies, is making a documentary about the phenomenon and would love to hear from you. Rodney writes:
I'm working on on a new film - it's about Sleep Paralysis, a surprisingly common phenomenon where people wake-up totally frozen from the eyeballs down, unable even to make a noise, and they frequently see sinister intruders and other disturbing visions. I've been obsessed with it ever since it used to happen with me (in my case, I saw sort of a living, 3D shadow looming over in me in judgement).
The film is going to be largely built on interviews with people who've had vivid, first-person experiences with it (and have given some serious thought to what's really happening to them) - if anyone wants to share their stories, the easiest way is to contact us via the film's Facebook page.
After eight years of development and a successful Kickstarter, BB pal Mitch Altman's Neurodreamer sleep mask is ready for shipping! You might recall that Mitch is the inspiring maker behind the TV-B-Gone, Trip Glasses, and a bunch of other delightful gadgets. The Neurodreamer is an open source light/sound machine integrated into a memory foam mask. Mitch says:
The NeuroDreamer sleep mask is an advancement over prior entrainment* devices which attempt to entrain the brain with only a single brainwave frequency at a time. The NeuroDreamer sleep mask uses up to four brainwave frequencies simultaneously (mixed at different amplitudes), to more closely replicate the full spectrum of frequencies present in a person who is falling asleep.
* "Entrainment" is the the process of externally presenting brainwave frequencies to the brain, allowing it to synchronize to those frequencies.
It's available for $69.95 in three different versions designed for Sleep, Lucid Dreaming, or Meditation. Mitch is having a sale right now: Entering the coupon code THANKS gets you 10% off everything in Mitch's Cornfield Electronics shop, including the Neurodreamer. I want one!
Max Hawkins's "Call in the Night" is an "experimental radio show" presenting recordings of people who volunteered to be woken up by a phone call to discuss their dreams, worries, emotions, and experiences. It's rather compelling and beautiful. You can sign up to be called at CallInTheNight.com.
Miles O'Brien has a wonderful piece on NewsHour about the neuroscience of sleep and other forms of brain-rest, including meditation. I was present for some of the taping and research, and I love how the story turned out.
Sleep deprivation can cause serious health and cognitive problems in humans. In short, it can make us fat, sick and stupid. But why do humans need so much sleep? Science correspondent Miles O'Brien talks to scientists on the cutting edge of sleep research and asks if there's any way humans might evolve into getting by with less.
This hummingbird is sleeping in a specialized research container connected to a machine that measures how much oxygen it is breathing. According to forrestertr7, who posted the video to YouTube, this experiment was part of research aimed at understanding the differences between the metabolism of hummingbirds and that of larger species. After its nap, the hummingbird was released back into the wild.
But what about the snoring? Does the hummingbird really need a tiny, little beak strip, or what? I asked science blogger Joe Hanson, who posted this video to Twitter earlier today, and he did some research. Turns out, it's not totally unreasonable to call that adorable little wheeze a "snore". But, at the same time, hummingbirds have very different biology than we do. A snore for them isn't the same as a snore for us.
Hummingbirds have incredibly high metabolic needs. To do all that buzzing around and to keep their tiny bodies warm, they eat the human equivalent of a refrigerator full of food every day, mostly in the form of high-energy nectar and fatty bugs. Because of their small size, they also lose a lot of body heat to the air. In order to preserve energy on cool nights, they have the ability to enter a daily, miniature hibernation called torpor.
...Just before morning, their natural circadian rhythms kick in and they start to thaw out, like heating a car engine on a cold day. What we see in the video is probably a bird coming out of torpor (which is what the scientists in the video were studying), starting to breathe in more oxygen to raise its body temperature, and making that adorable snoring noise.
