  • Neanderthal bone fragments discovered in northern Spain mimic hibernating animals like cave bears.
  • Thousands of bone fragments, dating back 400,000 years, were discovered in this "pit of bones" 30 years ago.
  • The researchers speculate that this physiological function, if true, could prepare us for extended space travel.

Mind uploading: Can we become immortal?

Is the quest to upload human consciousness and ditch our meat puppets the future—or is it fool's gold?

  • Technology has evolved to a point where humans have overridden natural selection. So what will our species become? Immortal interstellar travelers, perhaps.
  • Scientists are currently mapping the human brain in an effort to understand the connections that produce consciousness. If we can re-create consciousness, your mind can live on forever. You could even laser-port your consciousness to different planets at the speed of light, download your mind into a local avatar and explore those worlds.
  • But is this transhumanist vision of the future real or is it a pipedream? And if it is real, is it wise? Join theoretical physicist Michio Kaku, neuroscientist David Eagleman, human performance researcher Steven Kotler, skeptic Michael Shermer, cultural theorist Douglas Rushkoff and futurist Jason Silva.

  • There are a number of physical and mental health benefits to sun exposure, such as boosted vitamin D and serotonin levels and stronger bones.
  • Addictions are multi-step conditions that, by definition, require exposure to the addictive agent and have also been proven to have a genetic factor. Countless people are exposed to addictive things, but not all become addicted. This is because of the genetic component of addiction.
  • This large-scale study explores the link between sun-seeking behaviors and the genetic markers for addiction.
