Tanzania earthquake kills 11, injures more than 200

The quake struck 43km from Bukoba on the western shore of Lake Victoria

At least 11 people have been killed and more than a hundred injured after a magnitude 5.7 earthquake hit northern Tanzania. The quake struck 43km from Bukoba, a city on the western shore of Lake Victoria on Saturday, at a depth of 10km, the US Geological Survey said.

Tremors were felt as far away as western Kenya and parts of Uganda, which share the waters of Lake Victoria, and also in Kigali, Rwanda. The Associated Press news agency reported that the 11 who died were in brick structures, citing a regional police commander.

The Lantern of the Photuris Firefly

THE lantern, or light organ, of a particular Photuris firefly is covered with jagged scales that dramatically enhance the brightness of the light that the insect produces. * Jagged scales Consider: Researchers have found that tiny scales on the lantern surface of some fireflies form a corrugated pattern, somewhat like overlapping shingles or tiles. The scales tilt up at one end by just 3 micrometers —less than one twentieth the thickness of a human hair. Yet this tiny tilt lets the lantern shine almost 50 percent more brightly than it would if the scales formed an even surface!
