Raul Oaida poses with his bicycle propelled with a self-built jet engine inside a workshop before a road test in the back of his house in Deva, 245 miles outside of Bucharest January 12, 2013. Using his pocket money and sponsorship from various sources, Oaida, 19, made the engine in about 3 years and became the first Romanian to build a jet engine in the country after his compatriot Henri Coanda developed a jet engine for an airplane in 1910 in France, which is said to be the first ever jet engine. Oaida clocked a speed of up to 26 miles per hour with the jet bicycle during today's test.

Vehicles drive on the Third Ring Road on a very hazy winter day in Beijing January 12, 2013. Microscopic pollutant particles in the air have killed some 8,600 people prematurely in 2012 and cost $1 billion in economic losses in four Chinese cities, according to a study by Beijing University and Greenpeace. The study of pollutant levels of PM2.5, or particles smaller than 2.5 micrometres in diameter, in Beijing, Shanghai, Guangzhou and Xi'an called for PM2.5 levels to be cut to World Health Organisation guidelines, which would reduce deaths by over 80 percent, the China Daily newspaper reported.

Cattle drink water from what is left of a nearly dry watering pond in Frei Paulo, in the northeastern state of Sergipe, January 11, 2013. Brazil's Northeast is suffering its worst drought in five decades, according to the agricultural minister of Bahia State, threatening hydro-power supplies in an area prone to blackouts and potentially slowing economic growth in one of the country's emerging agricultural frontiers. Lack of rain has hurt corn and cotton crops, left cattle and goats to starve to death in dry pastures and wiped some 30 percent off sugar cane production in the region responsible for 10 percent of Brazil's cane output.
