Graphics chip maker, Nvidia, has produced a clever marketing campaign in which they use their Maxwell architecture based chips to render the lighting of the Apollo 11 lunar landing. They produced a video that shows in detail how they accounted for the behavior of light in the classic photo of Buzz Aldrin as he descended the ladder of the lunar lander.
Only 20 more shows to the otherwise arbitrary achievement of Episode #500. So while we wait a few months for that event, there were a few things that went unsaid from our most recent episode #480. This week we have more celebrity gullibility, how Facebook makes us suckers, Russian bigfoot nonsense, and punishments for bad science practices. Here is the latest version of The SGU Cutting Room Floor.
Discovery Channel’s D News YouTube channel recently posted a video with host Julian Huguet gushing over a new car that “runs on salt water.” Don’t get excited just yet. While this is an interesting approach to battery technology, as you will see it is not an energy solution.
An extensive study of galaxies reveals that the big ones grow primarily from cannibalizing the smaller ones. Small galaxies, on the other hand, are very efficient at creating new stars from scratch right up until they get gobbled up. This is just one of the fascinating results of a 7 year study by 90 scientists of
Florida oranges are in big trouble but genetic engineering may be able to save them.
Recent advances in an alternative battery technology using Betavoltaics could potentially power future cars and spaceships using electrons from radioactive decay.
“You wrap a tree trunk with ropes, and keep punching it. You throw 5,000 punches day and night — do that for a month, the inside of your fist swells up until you can barely curl your fingers … Then you open a tin can and set it up on a stand. You keep punching the sharp part. When your hand turns into mush with blood and pus, you start punching a pile of salt. Repeat it, and your hands become like a stone.”
The name reveals the most distinguishing feature. Animal mimicry is an oft-seen survival tactic in animals, but this octopus takes it to a whole new level in that it can actually imitate several toxic marine species to ward off potential predators.
A sleep circuit in the brain has been identified in the brainstem of mammals that, once stimulated, causes test animals to quickly fall asleep regardless of the time of day.
Researchers at Harvard School of Medicine and the University at Buffalo School of Medicine and Bio-medical Sciences found this so-called sleep node (the second ever found) in the brain stem of the mammalian brain. The brain stem is the communication hub of the brain being connected directly to your spine and relaying signals from you gray matter through and down your spinal cord. Much more importantly though, it is the life support system that handles low-level but kinda important functions like breathing, heart-rate, body temperature, blood pressure, and sleeping.
