US scientists to complete the most complex human brain directly connected experiments

About 100 billion neurons in the brain communicate with each other, forming 100 trillion synapses, the number of dense, better than the stars of the Milky Way. We can explore galaxies beyond the light-years, but we do not know much about the brain.
In 2013, the European Union and the United States have launched the "brain project" and "brain plan", respectively, within 10 years plans to invest 1 billion euros and 4.5 billion US dollars to the "final science fortress and the ultimate frontier" - "brain science"
In September, researchers at the University of Washington used a brain-to-brain approach that allowed five pairs of subjects to pass brain signals over the Internet to play quizzes. For the first time, this experiment proves that the two brains can be directly connected, and without the need for vocalization, one can accurately guess the other's ideas.
This is one of the most complex brain-brain experiments that humans have ever performed: the respondent wears an electroencephalograph (EEG) recording EEG activity. When he sees an object on the computer screen, such as a dog, Another interrogator also sees a set of possible objects and related problems. Click the mouse to ask the questioner to send a question, the respondent will answer yes or no by staring at the LEDs with different frequencies of flash on the monitor. Both answers send a signal to the interrogator via the Internet, activating the magnetic coil placed behind the head. But only the answer is "yes" to generate enough to stimulate the interrogator visual cortex of the signal, and let it see a wavy or fine linear flash, this phenomenon is called "vision." Through this feedback, the interrogator can confirm and point out the correct object.
The use of non-invasive connection, and invasive (such as implanted electrodes to the cortex) means, although the signal reception is relatively straightforward, but the signal transmission process is indeed circuitous and complex. However, brain - brain direct connection is the future of deep emotions, knowledge, memory and other "interactive" one of the bases, so even if only to achieve a Zhuopu "game", still gives people unlimited hope.
Thus, although the brain of the subject is only showing a temporary "yes" flash, but no less than 1866 Mendel in the famous pea hybridization test, was used to represent the different traits, and later on behalf of the gene group Upper and lower case letters.

The first close observation of human Pluto

The largest solar system members of the ups and downs to Pluto. Since 1930, Clyde Thompson found that Pluto's controversy has been relevant, even if the global textbooks have been known as the "ninth planet" name, and finally was kicked out in 2008, downgraded to " Dwarf planet ".
NASA launched a new field of vision in 2006, the target went straight to Pluto, 9 years later, the United States Eastern time at 14:45 on July 14, 2015, "New Horizons" close range Flying Pluto, became the first to detect the distant dwarf planet of human detectors.
"New Horizons" shaped like a grand piano, carrying a 77 kg propellant, including 10.9 kg of plutonium dioxide as a power source. It is by far the fastest detector, in less than 10 years, flying 4.8 billion kilometers. Its counterparts, as part of Pluto discoverer Clyde Thompson's ashes, and NASA solicitation of 450,000 signatures. On the road, it also visited the Saturn and Neptune.
Pluto had little knowledge of Pluto, the "meeting" to make the understanding of human Pluto revolutionary changes - its diameter is 2370.6 km (± 19.3 km), the density lower than previously thought, the internal may have More ice and less rock, scientists also confirmed that the Arctic is indeed as speculated by the ice composition, but also rich in methane and nitrogen ice.
At present, the "new horizon" probe is still on the line, will enter the mysterious edge of the solar system Kuiper belt, Kuiper belt object is considered to be formed during the solar system has not yet time to grow into a planet's wreckage, recording the solar system initially formed history , So the future "Kuiper Belt" trip, in a sense, is also a glimpse of the origin of the solar system.
"New Horizon" to visit Pluto, in the global media, astronomy, as well as the majority of science and technology enthusiasts of the carnival. There is no doubt that the first human close observation of Pluto, marking the golden age of the planet to explore the arrival of the summit.
