a team of astronomers just found Dracula's sandwich named after the national dish of Uruguay Dracula's chavito is a baby star 980 light years or so away surrounded by discs of gas and dust that kind of looks like a delicious sandwich fit for a vampire and it turns out this 35,000 year-old magic wand has a much more Earthly purpose the ancient Ivory baton discovered in Southwest Germany is now believed to be a stone age rope making tool it's actually a big deal to have some potential proof of hig

ched at the back that spins faster than a jet engine turbine the team behind the gyog glove gyro gear plan on miniaturizing the gyroscope in future versions of the hand stabilizing glove in robots with muscles news researchers from Japan engineered a two-legged biohybrid Rob robot that is combining muscle tissues with artificial materials inspired by the way humans walk this biohybrid robot is more flexible and can walk and pivot they explain using muscle as actuators allows us to build a compac
t robot and Achieve efficient silent movements with a soft touch it has a foam buoy top and weighted legs allowing it to stand straight underwater and its ability to flex and bend is thanks to being constructed with silicone rubber manually zapping the muscles at different speeds and time intervals scientists were able to make it walk forward and turn and they hope to increase the walking speed in the future by integrating the electrodes into the robot itself a new DVD sized disc can hold more t
han 1 million gigabits more than the entire internet puts out per second by storing the information in three dimensions instead of the standard two scientists have developed a way to encode data on 100 layers in Optical discs using spots as small as 54 nanom wide oneth of the size of the wavelengths of visible light used to even read and write the data that's roughly 4,000 times as much data as a Blu-ray disc and 24 times as much as the most advanced Hard dis currently available to write they us
e a green 515 nanomer laser which triggers spot formation and a second red 639 nanom laser switches off the writing process to then read first a blue 480 nanom laser makes spots fluorescent while a second orange 592 nanom light switches off the fluoresence process currently the writing speed is 100 milliseconds and energy consumption of microj to Mill the scientists would love to see this used in Big Data Centers with improved writing speed and energy consumption these birds just scored as high
as primates in cognitive tests six Oriental pied horn bills were given various tests of object permanence with three of the birds passing all six stages using treat rewards the researchers tested the bird's abilities to observe where the treats started and after being hidden under cups and moved where they ended up even if they couldn't be seen coincidentally or not coincidentally the three birds that didn't make it to the last stage had no breeding experience because to safely lay eggs and take
care of them the female Oriental Pi horn will envelop themselves in their homes with things like lumps of mud poop saliva fruit and bark they leave only a narrow slot for the males to bring them food the male horn bills in turn have to be able to understand that their mate still exists in there even if they can't see them so add Oriental pied Horn Bill to the list of very clever birds and now the most epic ad I've ever seen for the GE cassette tape player thanks to all my patrons mind blowing i
