For years, poor sleep has been linked to a host of medical conditions such as obesity, diabetes, heart disease, mood disorders and even alcohol dependency. Now a new study published in SLEEP suggests there may be an even bigger problem to worry about: a shrinking and weakening brain.
The study, conducted by researchers from Duke-NUS Graduate Medical School Singapore, focused on a group of 66 Chinese adults. Every two years, the participants were asked to take a sleep questionnaire, as well as MRI scans and neuropsychological assessments. The result: People who had trouble sleeping had “greater age-related brain atrophy and cognitive decline” than those who rested well every night. —

And yet we still lionize those who sleep under their desks.
There are a few people whom I end up respecting for this behavior, because they can’t help cramming in a few extra hours of super-weird thinking time to work out the stuff they’re working through.
For most of us, however, the “late to bed, early to rise, grinding it out” startup mentality is just pretty fucking stupid.
Unless you’re a genetic anomaly [and you’re probably not, no matter how “used to” five or six hours of sleep a night you are], you are achieving less than you could because you’re sleep deprived.
The most indicative metric of a community’s health is the cross-pollination of stakeholders. Etsy sellers buy from other Etsy sellers, Kickstarter creators back other Kickstarter creators, and Meetup attendees start new Meetups. — bwats

So many people glorify and romanticize “busy”. I do not. I value purpose. I believe in resting in reason and moving in passion. If you’re always busy/moving, you will miss important details. I like the mountain. Still, but when it moves, lands shift and earth quakes. — Joseph Cook

In the consumer internet, many of the most interesting technology platforms are, at their core, networks.

My parents taught me that even though it’s not forever — because it’s not forever — being alive is a profoundly beautiful thing for which each of us should feel deeply grateful. — Sasha Sagan
No natural phenomenon on Earth will be hotter. Like the sun, the cloud will go nuclear. The zooming hydrogen atoms, in a state of extreme kinetic excitement, will slam into one another, fusing to form a new element—helium—and with each atomic coupling explosive energy will be released: intense heat, gamma rays, X rays, a torrential flux of fast-moving neutrons propelled in every direction. There isn’t a physical substance that could contain such a thing. Metals, plastics, ceramics, concrete, even pure diamond—all would be obliterated on contact, and so the machine will hold the superheated cloud in a “magnetic bottle,” using the largest system of superconducting magnets in the world. Just feet from the reactor’s core, the magnets will be cooled to two hundred and sixty-nine degrees below zero, nearly the temperature of deep space. Caught in the grip of their titanic forces, the artificial earthbound sun will be suspended, under tremendous pressure, in the pristine nothingness of iter’s vacuum interior. — Science is amazing.
