“ The worst the bicycle scored, under varying conditions, was 81 percent efficiency. ” James Spicer, who led the study, said: “This was amazing to me, especially when you realize the essential construction of this chain drive hasn’t changed in more than 100 years. ” “ Evil Rain ” A natural phenomenon known as evil rain occurs in Turpan, in the Sinkiang Uighur Autonomous Region of China. Even as dark rain clouds pass overhead, the weather may remain hot and dry on the ground, reports China Today. Rain appears to be falling from the sky, and a person can even feel the rain by waving his hand up in the air. However, in the extremely arid climate of Turpan, evaporation takes place at a much faster rate than the rain falls. Thus, the “evil rain ” evaporates before it ever reaches the ground. Deadly Diet A veterinary surgeon in the Kutch district of western India recently removed 100 pounds [45 kg] of plastic bags from the stomach of a sick cow, reports The Week, a magazine of Kerala, India. Besides the bags, he also found cloth, coconut husks, a coil of wire, and a screw. Stray cows in India subsist mainly on garbage, and discarded plastic bags are dangerous for them. Even privately owned milk cows often eat roadside garbage when moving to their grazing areas. The veterinarian, Dr. Jadeja, says that consumption of plastic is second only to foot - and - mouth disease as a problem for the cows. The indigestible material blocks the abdomen, so that the cow cannot chew the cud. Such cows are often left to die. Dr. Jadeja was alerted to the situation by cobblers who found masses of plastic in the stomachs of dead cows when removing their hides.
