SAN FRANCISCO Discount Womens UGG Bailey Button Sheepskin Short Boots 5803 Navy , April 30 (Xinhua) -- A game developed by the University of Washington (UW) Center for Game Science in partnership with the Allen Institute for Brain Science enables citizen scientists to produce complete, three-dimensional reconstructions of neurons from different regions of the brain in animals and people.
With the game Cheap Womens UGG Bailey Button Sheepskin Short Boots 5803 Sand , known as Mozak, which was launched in November Womens UGG Bailey Button Sheepskin Short Boots 5803 Black Clearance , novice players numbering roughly 200 a day and Allen Institute neuroscientists have been able to reconstruct neurons 3.6 times faster than previous methods.
The players have outperformed computers at tracing the complicated shapes of neurons. They can produce reconstructions that are 70 to 90 percent complete, compared to roughly 10 to 20 percent for the most effective computer-generated reconstructions.
Mozak shows players a magnified volumetric image of a neuron Womens UGG Bailey Button Sheepskin Triplet Boots 1873 Black Outlet , which a key type of brain cell that transmits information throughout the nervous system, and asks the viewer to trace or draw its visible branches Womens UGG Bailey Button Sheepskin Triplet Boots 1873 Chestnut Online , which can also appear as disconnected dots in more challenging areas of data.
Many neurons have delicate and highly branched structures that human eyes can distinguish far better than computers alone. People also tend to be much better at inferring the likely detailed structure from faint and sometimes discontinuous data. Yet computers are better at performing tedious tasks that can take humans a long time and are faster at reconstructing from clear and continuous data. Mozak brings together people and computing in a new way, to solve this enormous problem together.
"This is not a story about people beating computers because people are using subsets of these computational tools Wholesale Womens UGG Bailey Button Sheepskin Triplet Boots 1873 Grey ," said Center for Game Science director Zoran Popovic, a professor at the Paul G. Allen School of Computer Science & Engineering. "This is about leveraging the things that computers can do well and the things that people do really well when they're trained Cheap Womens UGG Bailey Button Sheepskin Triplet Boots 1873 Sand , forming a symbiotic superpower capable of solving unsolved challenges in science."
The creation of Mozak was inspired partly by the growing needs for analyzing data generated by global projects like the BRAIN initiative, said neuroscientist Jane Roskams ugg boots leather ireland , who served on the BRAIN advisory working group.
Until recently, neuroscience labs were doing well to trace about one neuron a week ugg boots sand ireland , said Stephen Smith, senior investigator for the Allen Institute for Brain Science. Mozak can speed that progress ugg boots grey ireland , but fully understanding neural networks will require tracing many thousands of neurons.

HOHHOT， March 29 (Xinhua) -- A total of 16 people suspected of causing an explosion in a residential building in northern China's Inner Mongolia Autonomous Region have been detained， local police announced Wednesday.
The accident at about 2 p.m. Saturday in a multi-story residential building in Tumd Right Banner， Baotou city， caused part of the building to collapse.
Five people were killed and another 25 injured in the incident.
Police said the explosion was caused by spontaneous combustion of explosives that had been illegally stored in the building.

LIVERPOOL， Britain， Aug. 15 (Xinhua) -- They became world famous as four lads who shook the world. But on the cusp of becoming a global music phenomenon in the 1960s， one man put the Beatles on the map.
In the days before the internet and social media， thousands of Beatles fans flocked to dance halls across Britain， thanks to Tony Booth， known as the eight-days-a-week poster artist.
He was responsible for hand-painting posters advertising gigs by the Beatles and other performers， such as singer Cilla Black.
It was non-stop work for Booth with so many concerts and gigs taking place in the early 1960s.
Now almost 60 years later， Booth， now 83， is holding his first ever exhibition， featuring his iconic poster art.
His exhibition is taking place later this month during International Beatles Week at View Two Gallery in Mathew Street， just meters away from the Cavern Club， birthplace of the Beatles era， which remains as one of Liverpool's top tourist attractions.
Booth is faithfully reproducing by hand 40 of his favourite posters， using the same roll of paper he used in the 1960s.
He was originally hired to produce sales posters for a family furniture company， until one of the family members， Brian Epstein， became the manager of the Beatles.
Thousands of the posters he painted were thrown into rubbish baskets as soon as concerts had taken place. Little did people know they were discarding pieces of valuable history.
One of only a handful of surviving original posters was sold at a London auction house last year to an American collector for almost 36，000 U.S.dollars.
Booth told Xinhua: "This was the days before the internet and social media and my posters were the main way of telling fans of upcoming gigs by the Beatles and other stars of the 1960s Mersey Beat era."
"I produced thousands of them， each earning me a few shillings. But it was steady regular work. I never imagined in a million years they would one day be so valuable. I wished I'd kept some myself， but they were simply thrown in the waste paper basket，" said Booth who was trained as a poster artist after leaving school at the age of 15.
"I got to know Brian Eps.
