The biology of aliens: How much do we know?

Hollywood has created an idea of aliens that doesn't match the science.

  • Ask someone what they think aliens look like and you'll probably get a description heavily informed by films and pop culture. The existence of life beyond our planet has yet to be confirmed, but there are clues as to the biology of extraterrestrials in science.
  • "Don't give them claws," says biologist E.O. Wilson. "Claws are for carnivores and you've got to be an omnivore to be an E.T. There just isn't enough energy available in the next trophic level down to maintain big populations and stable populations that can evolve civilization."
  • In this compilation, Wilson, theoretical physicist Michio Kaku, Bill Nye, and evolutionary biologist Jonathan B. Losos explain why aliens don't look like us and why Hollywood depictions are mostly inaccurate.

3 scientists school flat Earthers on the evidence

Can this end flat-Earth theory once and for all?

  • Despite centuries of evidence proving otherwise, there are an alarming number of people around the world who genuinely believe that the earth is flat. Bill Nye The Science Guy, NASA astronomer Michelle Thaller, and Neil deGrasse Tyson strongly disagree.
  • From simple experiments like standing at a seashore or looking through a telescope at other planets, to reading about navigation or viewing photos of Earth taken from space, the scientists share several ways that flat Earthers can see the truth for themselves.
  • Tyson explains why this trend doesn't qualify as a scientific debate and why it is actually dangerous for people to believe and, even worse, pass on these objectively false ideas.

Should you "hack" your sleep pattern?

Living like a genius and finding ways to "optimize" sleep is not necessarily good for your health. Here's why.

  • A seemingly common trait of geniuses like Nikola Tesla and Leonardo da Vinci is that they operated (and excelled) on very few hours of sleep per night. BrainCraft's Vanessa Hill explains that while unorthodox sleep patterns may have worked for them, your mileage may vary. Attempting to sleep like a genius could "wreak havoc" on your brain and be detrimental to your health.
  • There are three different types of sleep patterns: monophasic sleep (one chunk at night for a recommended 6-8 hours), biphasic sleep (two chunks in a 24-hour period), and polyphasic sleep (three or more chunks in a 24-hour period). While sleeping, you cycle through four stages: two light, one deep, and one REM.
  • Switching sleep patterns can disrupt these stages, as can consuming alcohol. So while attempting to maximize your creative time, you may be denying your brain and body the time it needs to recover, which can be dangerous.

Inside the brains of psychopaths

Three scientists examine three dimensions of psychopathy: neurological, social, and criminal.

  • How are the brains of psychopaths wired differently? In this video, psychologist Kevin Dutton, neuroscientist (and psychopath himself) James Fallon, and professor of psychiatry Michael Stone take the wiring apart.
  • In neurotypical people, the amygdala and the orbitofrontal cortex inhibit one another to allow for reasonable, moral decision-making. Psychopaths don't have that mechanism.
  • Up to 80% of who a psychopath will turn out to be is down to environment. Intelligence, natural aggressiveness, and your family and friends determine whether a psychopath will grow up to make a killing or just "make a killing in the market," as a famous headline once said.
