Brain-machine interfaces have already allowed primates to manipulate virtual objects with virtual arms. The technology could ultimately benefit the paralyzed, allowing them to walk.
What's the Latest Development?
Scientists at Duke University have engineered a powerful brain-machine interface that allows primates to "move" a virtual arm with their mind and "feel" different textures belonging to virtual objects. Electrodes placed on the primates' motor and somatosensory cortex connected their brains to the virtual world created by scientists. While past interfaces have measured 50 to 100 neurons, this new method records thousands of movements at once, an order of magnitude greater which allows for more sophisticated manipulations.
What's the Big Idea?
Scientists are increasingly able to merge the mind with machines in the external world. Monkeys have already demonstrated control of a robot arm using a brain-machine interface. Advancements made in tactile interfaces also hold promise for individuals with spinal cord injuries. Researchers' ultimate goal will be to build a human exoskeleton that routes mental commands directly to machine parts that will in turn manipulate the limbs. Living in a wheel chair could become obsolete within our lifetime.
Delay, deny and deflect were the strategies Facebook has used to navigate scandals it's faced in recent years, according to the New York Times.
- The exhaustive report is based on interviews with more than 50 people with ties to the company.
- It outlines how senior executives misled the public and lawmakers in regards to what it had discovered about privacy breaches and Russian interference in U.S. politics.
- On Thursday, Facebook cut ties with one of the companies, Definers Public Relations, listed in the report.
Protected animals are feared to be headed for the black market.
Dogs' floppy ears may be part of why they and other domesticated animals love humans so much.
- Nearly all domestic animals share several key traits in addition to friendliness to humans, traits such as floppy ears, a spotted coat, a shorter snout, and so on.
- Researchers have been puzzled as to why these traits keep showing up in disparate species, even when they aren't being bred for those qualities. This is known as "domestication syndrome."
- Now, researchers are pointing to a group of a cells called neural crest cells as the key to understanding domestication syndrome.
