The mathematics of mind-time
The special trick of consciousness is being able to project action and time into a range of possible futures.

At the Storage Developer Conference, Microsoft presented a new paper that talks about how data can be stored in quartz glass cubes using laser light. The project is done in collaboration with University of Southampton Optoelectronics Research Centre. You can check out the full video of the Storage Developer Conference below.
The idea is to help companies store data easily and not compromise with the speed or the performance of the servers.

Det er da selvfølgelig et neurostimulations-pandebånd. Georg Gearløs’ tænkehat findes nu i virkeligheden. Det er noget med at bestemte områder i hjernen får tilført meget små impulser af strøm — man kan indstille den så den øger koncentrationsevnen — eller kreativiteten! Efter sigende. Skal jeg have den på næste gang jeg freestyler? Selvfølgelig skal jeg det. Glæder mig til at aflægge rapport PlatoScience 😬

DART is a test of the kinetic impactor technique, a potential method to deflect an asteroid on course to impact the Earth. Kinetic impactors are one of only a small number of approaches we think are mature enough to deploy in the near future if they are needed (though we hope they won’t be). The most powerful asteroid-deflection technique is the use of a nuclear device. While such a device makes for good (and bad) sci-fi movies, there is widespread desire to develop alternate techniques.
The kinetic impactor concept is rather straightforward: ram the threatening object with a spacecraft and change its orbit so that it misses our planet. In theory, we could heave ever-larger masses at ever-faster speeds to deflect ever-larger objects. However, we think there is a practical limit — we don’t want to break up an incoming object into several pieces, lest we replace one big impact with multiple, only-slightly-smaller impacts. Exactly where that tradeoff lies is still uncertain, but we believe we can keep an object intact if we change its speed by less than the object’s own escape speed. In other words, since we think a lot of these objects are loose aggregates of gravel held together by gravity, we don’t want to shove so hard that we accidentally overcome that weak gravity and disperse the gravel.
In the middle of the Atlantic Ocean, hundreds of feet underwater, the Greek goddess of love lives on—in the form of a dazzling reef fish.
In a new study published on Tuesday in ZooKeys, researchers from the California Academy of Sciences describe a new species of anthias, a common type of reef fish, named Tosanoides aphrodite or the Aphrodite anthias. The pink and yellow creature so transfixed researchers when they discovered it during a deep-water dive that they didn’t notice a large sixgill shark swimming directly above them.
“This one is without a doubt the most spectacularly colored fish I’ve ever described,” says Luiz Rocha, an ichthyologist with the California Academy of Sciences, in an email.
