Kenyan Boy Scares Lions With Ingenuous Invention

Kenyan Boy Scares Lions With Ingenuous InventionLiving on the edge of Nairobi National Park, in Kenya, 13-year-old Richard Turere first became responsible for herding and safeguarding his family’s cattle when he was just nine. But often, his valuable livestock would be raided by the lions roaming the park’s sweet savannah grasses, leaving him to count the losses. So, at the age of 11, Turere decided it was time to find a way of protecting his family’s cows, goats and sheep from falling prey to hungry lions.

‘Simple and low-cost’

His light bulb moment came with one small observation. Turere realized that lions were afraid of venturing near the farm’s stockade when someone was walking around with a flashlight. He put his young mind to work and a few weeks later he’d come up with an innovative, simple and low-cost system to scare the predators away.

He fitted a series of flashing LED bulbs onto poles around the livestock enclosure, facing outward. The lights were wired to a box with switches and to an old car battery powered by a solar panel. They were designed to flicker on and off intermittently, thus tricking the lions into believing that someone was moving around carrying a flashlight.

‘Remarkable ingenuity’

And it worked. Since Turere rigged up his “Lion Lights,” his family has not lost any livestock to the wild beasts, to the great delight of his father and astonishment of his neighbors. What’s even more impressive is that Turere devised and installed the whole system by himself, without ever receiving any training in electronics or engineering.

The 13-year-old’s remarkable ingenuity has been recognized with an invitation to the TED 2013 conference, being held this week in California, where he’ll share the stage with some of the world’s greatest thinkers, innovators and scientists.

And The Happiest States In The U.S. Are…

And The Happiest States In The U.S. Are...If you’re sick of cheerful, happy people, it might be wise to avoid Hawaii or Napa, California. They were found to be the United States’ happiest state and city, respectively, in a recent study of geotagged tweets.

‘Fondness for profanity’

Researchers at the University of Vermont sifted through more than 10 million geotagged tweets from 2011 to map out the moods of Americans in urban areas. They ranked the locations based on frequency of positive and negative words using the Mechanical Turk Language Assessment word list.

Maine, Nevada, Utah and Vermont round-out the top five happiest states list, following rainbow and beach-filled Hawaii. Louisiana was found to be the saddest state, followed by Mississippi, Maryland, Michigan and Delaware. One reason for Louisiana’s low cheeriness ranking (they must not have measured during Mardi Gras) is its inhabitants’ fondness for profanity.

‘Coastal areas were more chipper’

The study, which was broken down by The Atlantic, also looked at the results for 373 urban areas to rank the happiest and least-happy cities. Vacation destination Napa, California, was determined to be one of the happiest cities along with Longmont, Colorado; San Clemente, California; Santa Fe, New Mexico; and Santa Cruz, California.

The five most bummed-out cities according to average word choices were Beaumont, Texas; Albany, Georgia; Texas City, Texas; Shreveport, Louisiana; and Monroe, Louisiana. Again, researchers found liberal use of swear words to be a key factor in a city’s overall happiness score. Coastal areas were more chipper than landlocked areas, and the cities with a higher density of tweets tended to be less happy.

The research shows that social networks have a lot of promise for these types of surveys, and also that there are still some major limitations. Researchers point out that only 15% of online adults are using Twitter, and those users don’t accurately represent the demographics of the United States.
