TOKYO — A magnitude-6.7 earthquake rattled northeast Japan early today in the same area where a massive quake triggered a deadly tsunami in March, but there were no immediate reports of injuries or damage.
The Japan Meteorological Agency issued a tsunami warning for the region after the quake, but canceled it about an hour later.
The temblor struck the region of the Pacific where a magnitude-9.0 quake hit on March 11, triggering a huge tsunami. At least 23,000 people were killed or left missing in those disasters, which destroyed hundreds of homes, offices and factories in northeastern Japan.
Mix of E. coli strains blamed in food crisis
LONDON — A mix of two dangerous E. coli strains caused the recent deadly food poisoning outbreak in Germany, according to a new study of the bacteria's DNA.
Scientists said the E. coli outbreak strain combined one that makes a toxin and another that sticks to the gut in a way that potentially speeds up the body's absorption of the toxin. They described it as "unprecedented" in its lethality.
"The two strains are in themselves quite nasty," said Hugh Pennington, an emeritus professor of microbiology at the University of Aberdeen, who wrote an accompanying commentary on the research.
First lady calls on young Africans to lead
JOHANNESBURG — Michelle Obama on Wednesday told young African leaders, including members of South Africa's post-apartheid generation, that there are more causes worth fighting for and more history to be made. She urged them to be the ones who end hunger, wipe out HIV/AIDS and protect women's rights.
In an emotionally stirring speech at a church that became a popular refuge during the fight against government-imposed segregation in South Africa, America's first lady drew on the struggle for racial equality in the U.S. and in this country as she sought to inspire young people to become the next generation of problem-solvers.
"I know that as your generation looks back on that struggle and on the many liberation movements of the past century, you may think that all the great moral struggles have already been won," Obama said. "But while today's challenges might not always inspire the lofty rhetoric and high drama of struggles past, the injustices at hand are no less glaring. The human suffering is no less acute."
