  • Kelly Walters, neuroscientist and professor of psychiatry, has spent decades studying the brains of serial killers, sociopaths, and men with personalities built around protein supplements.

    “We expected we may find answers for the lack of moral development in the prefrontal cortex but we were shocked to find anomalies that go far beyond the brain,” said Walters. “We gave full body MRIs to a large number of ICE agents and discovered that inside their chest cavity, where we would see a heart in an ordinary person, is actually just a screaming void. You could actually hear it through the image which was really quite astounding.”










  • Apparently biodiesel can be made from algae, which could actually work well. Mass farm algae, which can absorb a lot of co2, use some of it to make biodiesel, but overall grow way more algae. Either way though it has a lot of input options of things that are mostly waste as it stands now

    I think one of the major benefits is not shipping raw oil and finished fuel all over the world. This is something sustainable, but more importantly domestically viable. Just not shipping oil all the way here from the middle east or Venezuela or wherever is an improvement.

    Plus, in a dark side type way, we can sell our own domestic petroleum products to other countries a la Norway

    At this point we really just need some stop gaps to get us to a point where some renewable has a more major breakthrough. Be it fusion or solar panel efficiency or geothermal or battery tech or whatever have you




  • In terms of biology, the reason for this head bobbing behavior is because of how owl eyes have adapted to being nocturnal predators. Owls have amazing night vision, which comes from having an incredible number of rod receptors in their eyes. Rod receptors are extremely sensitive to low light environments. These are peripheral vision receptors that enable a wide angle of alertness for even the slightest movements, which is great for spotting tiny mammals as they graze along the tall grass in open fields.

    The downside is these rods are basically color-blind and require lots of space in the eye for the high numbers required to work in near complete darkness. In order to fit the most rod receptors possible in their eyes, owls lose the ability to move their eyes in the sockets. The extra space enables them to fit more rod receptors, but it removes their ability to manually focus their eyes.

    This means owls need a specialized strategy to help them judge distance that replaces movement of the eye with movement of the entire head.

    One of the fascinating things about this is humans have this capability too, but most people never learn how to develop it. Humans typically judge distance with our cone receptors by adjusting the focus of our eyes along an axis of visual depth.

    You can feel this subtle adjustment in your eyes by focusing your gaze on something far away, then move the focal point to something much closer and feel what happens to your eyes. If you’re attentive, you will feel a slight micro-movement of your eyes as they adjust.

    This type of cone-based depth adjustment is something that owls cannot do so they compensate by moving their heads to generate the motion parallax effect (rod based depth perception)
