   Il existe un virus répandu appelé ransom #WannaCry, qui infecte les dispositifs de l'entreprise et du gouvernement. Les pirates font l'ordre de rançon avec une monnaie numérique. Les sites Web du gouvernement ont été piratés, alors n'ouvrez aucun message sur votre ordinateur ou votre téléphone ...   Il y a une attaque accablante sur les ordinateurs et les téléphones par le pirate. Cette attaque a été affectée par des hôpitaux en Grande-Bretagne et diverses entreprises dans le monde. Cette attaque est la plus dangereuse. Les pirates informatiques exigent une rançon pour le retour des fichiers chiffrés. Les ordinateurs ont été arrêtés dans les salles d'opération des hôpitaux et d'autres ont été annulés. ... Cette image est au dessus de ce qui arrive aux ordinateurs, alors faites attention à qui vous pouvez atteindre.   Image de propagation du virus Ransom WannaCry WCry est actuellement dans le monde entier!  

    There is a widespread virus called ransom #WannaCry, infecting corporate and government devices. Hackers order ransom with a digital currency. Government websites have been hacked, so please do not open any messages on your computer or phone ...      There is an overwhelming attack on computers and phones by the hacker. This attack was affected by hospitals in Britain and various companies in the world. This attack is the most dangerous. The hackers are demanding a ransom for the return of encrypted files. The computers were stopped in the operating rooms of hospitals and others were canceled. ... This picture is above what happens to the computers, so be careful with whom you may reach. Image of ransom virus spread #WannaCry #WCry is currently around the world!

Last year , scientists imaged the human brain on LSD for the first time, showing how the powerful psychedelic activates regions and causes them to connect with each other in totally new and unified ways. It was the first solid evidence of the drug's ability to change the way our brains function. Now, researchers want to test whether microdosing LSD - taking a small amount that doesn't have a hallucinogenic effect - can offer the same mental boost. And they're planning to pit microdosed humans against AI in the ancient Chinese game of Go to do it. The idea came from lead researcher Amanda Feilding, who took LSD (lysergic acid deithylamide) daily before work to boost her productivity and creativity before it was made illegal in 1968. Back then, she also played a lot of Go in her spare time. "I found that if I was on LSD and my opponent wasn't, I won more games," Feilding told Daniel Oberhaus from Motherboard . "For me, that was a very c...

Researchers have developed a new kind of transistor laser that can switch between two stable energy states – electronic and photonic – which could one day enable data transfer 100 times faster than conventional digital devices. The transistor prototype features what's called bistability – the capability for a single switch to alternate between optical and electrical signal output – and could help lead to the development of light-based computer systems where data is shuttled in between semiconductors by photons instead of simply electrons. "Building a transistor with electrical and optical bistability into a computer chip will significantly increase processing speeds," says microelectronics engineer Milton Feng from the University of Illinois at Urbana-Champaign, "because the devices can communicate without the interference that occurs when limited to electron-only transistors." In conventional electronic devices, microchips are made up of b...
