SEO stands for “search engine optimization.” It is the process of getting traffic from the “free,” “organic,” “editorial” or “natural” search results on search engines.
Tractor-trailers without a human at the wheel will soon barrel onto highways near you. What will this mean for the nation’s 1.7 million truck drivers? Roman Mugriyev was driving his long-haul 18-wheeler down a two-lane Texas highway when he saw an oncoming car drift into his lane just a few hundred feet ahead. There was a ditch to his right and more oncoming cars to his left, so there was little for him to do but hit his horn and brake. “I could hear the man who taught me to drive telling me what he always said was rule number one: ‘Don’t hurt anybody,’” Mugriyev recalls. But it wasn’t going to work out that way. The errant car collided with the front of Mugriyev’s truck. It shattered his front axle, and he struggled to keep his truck and the wrecked car now fused to it from hitting anyone else as it barreled down the road. After Mugriyev finally came to a stop, he learned that the woman driving the car had been killed in the collision. Could a computer have done bette...
Scientists are making remarkable progress at using brain implants to restore the freedom of movement that spinal cord injuries take away. The French neuroscientist was watching a macaque monkey as it hunched aggressively at one end of a treadmill. His team had used a blade to slice halfway through the animal’s spinal cord, paralyzing its right leg. Now Courtine wanted to prove he could get the monkey walking again. To do it, he and colleagues had installed a recording device beneath its skull, touching its motor cortex, and sutured a pad of flexible electrodes around the animal’s spinal cord, below the injury. A wireless connection joined the two electronic devices. The result: a system that read the monkey’s intention to move and then transmitted it immediately in the form of bursts of electrical stimulation to its spine. Soon enough, the monkey’s right leg began to move. Extend and flex. Extend and flex. It hobbled forward. “The monkey was thinking, and then b...
Swiss Researchers Built a Robot Fish That Other Fish Will Follow. In associate degree study to examine if animals can react to robotic tries to move with them, Swiss researchers have designed a robotic fish that may with success imitate and mingle with zebrafish."We created a sort of 'secret agent' that may infiltrate these faculties of little fish," says Frank Bonnet of Swiss Federal Institute of Technology in Lausanne (EPFL). EPFL researchers selected the tiny fish thanks to their abrupt bursts of movement. It's troublesome to make an automaton that may integrate into a species like a zebrafish, that have a deeply developed "lateral line network," a sensory network evolved to observe the pattern of water movement. This sense is what permits fish like zebrafish to suddenly modification directions as a gaggle. The scientists thought-about the physical characteristics of zebrafish, such shape, colour and stripe once choosing a species to review. T...
