Facebook turned into tool for identifying fish


Facebook is well-known for connecting friends, publicising events and allowing people ample space for themselves. But recently, a scientist conducted a fish survey using the social networking tool.
In January, doctoral candidate Devin Bloom of the University of Toronto helped conduct the first ichthyological (fish) survey on Guyana's remote Cuyuni River.
Led by Oregon State University's Brian Sidlauskas, the goal was to find which species of fish live in the Cuyuni and get a good estimate of their abundance, according to a Toronto statement.
During the survey, Bloom and the research team spent two weeks catching as many fish as they could. They even slept in makeshift jungle camps. But after collecting more than 5,000 specimens, the team had a big problem.
In order to get the fish out of the country, the research team needed an accurate count of each species and provide a detailed report to the Guyanese government.
Since the team had to return to North America as soon as possible, they had just a few days to identify thousands of fish specimens.
That's when Bloom, who isn't exactly the most tech-savvy guy out there, suggested Facebook. Sidlauskas loved the idea, so he uploaded photos of each species.
And in less than 24 hours, their network of friends -- many of whom hold PhDs in ichthyology and are 'diehard fish-heads' -- had identified almost every specimen.
With 5,000 identifications in hand, the team was able to deliver their results to the government and return home on schedule.
The team's novel use of Facebook to accurately crowdsource scientific data could change the way academics view social networking.
It has certainly led Bloom to change his mind about the value of online tools. 'Social networking is so powerful,' he says, 'and scientists should be using it more to connect with the world-at-large.'

Solar plane makes maiden international flight

Solar plane makes maiden international flight


A solar energy plane made the world's first international flight powered by the sun on Friday to show the potential for pollution-free air travel.
The Solar Impulse took off from an airfield at Payerne in westernSwitzerland on Friday morning and landed at Brussels airport after a 13-hour flight.
"The objective is to demonstrate what we can do with existing technology in terms of renewable energy and energy savings," project co-founder and pilot Andre Borschberg told Reuters by telephone during the flight.
Borschberg believes such solar-harnessing technology can be used to power cars and homes. "It is symbolic to be able to go from one place to another using solar energy," he said.
The Solar Impulse project began in 2003 with a 10-year budget of 90 million euros ($128 million) and has involved engineers from Swiss lift maker Schindler and research aid from Belgian chemicals group Solvay.
The plane, which requires 12,000 solar cells, embarked on its first flight in April 2010 and completed a 26-hour flight, a record flying time for a solar powered aircraft, three months later.
With an average flying speed of 70 km/h (44 mph), Solar Impulse is not an immediate threat to commercial jets, which can easily cruise at more than 10 times the speed. A flight from Geneva from Brussels can take little more than an hour.
Project leaders acknowledged it had been a major challenge to fit a slow-flying plane into the commercial air traffic system.
Friday's flight was Solar Impulse's fifth. Previous flights did not leave Switzerland. A larger prototype is scheduled to fly around the world in 2013.
