Not for squemish..... I cannot fathom the clear images of the fangs.... HUGE. Curious to know more about that snake. Where is a herpetologist when you need one? https://www.facebook.com/reel/781302411506080

The black colored snake, if venomous? seems to have landed a sold bite on the rattler or copperhead. Will a good solid bite of two venomous snakes often, be fatal? https://www.facebook.com/reel/3414990811997775

This was a delight to watch. He's definitely one of us! Let me know what you think about this video. Enjoy!

Why does DNA use only right-handed sugars while proteins use only left-handed amino acids? Is this an accident of evolution on Earth, or is deeply woven into the fabric of life? If it is, then we could expect all DNA-based life anywhere in the Universe to use similar molecules, in which case visiting aliens might choose to eat us. (But we then we may ultimately be saved by microbes as in War of the Worlds.) A new paper presents an interesting hypothesis, and data to back it up, that the this handedness is fundamental. The great Sabine Hossenfelder explains. I should say that I am highly skeptical of this result. But this is a delightful video about an extremely interesting new experiment. Enjoy!
