MAZAR-I-SHARIF， Afghanistan， Jan. 20 (Xinhua) -- At least two persons were killed Friday evening after a bomb struck the ground of Buzkashi， a national game， in the Afghanistan's northern province of Balkh， provincial police spokesman said.
"The initial information found two persons were killed and two others wounded after an Improvised Explosive Device (IED) was detonated at a Buzkashi ground in Khulm District. The number of the casualties is likely to rise，" spokesman Shir Jan Durrani told Xinhua.
The causalities were shifted to a hospital in provincial capital of Mazar-i-Sharif city， the official added.
Security forces have cordoned off the area for precautionary measures. No group has claimed responsibility for the attack yet.
WASHINGTON Cheap Air Max 97 Online , Sept. 19 (Xinhua) -- Deleting a common gene in a breed of butterflies can broadly change their wing patterns, according to a study published recently in the U.S. scientific magazine Proceedings of the National Academy of Sciences.
Arnaud Martin, an evolutionary geneticist at George Washington University and one of the authors of the study, said they used butterfly wing patterns as a proxy to understand fundamental rules about the function of genes.
Butterfly wings vary in color and shape and have different functions. Some butterflies have brightly colored wings to warn predators that they are poisonous. Some have dull camouflage wings Cheap Air Max 90 Online , enabling them to pass off as leaves or barks.
The scientists chose butterfly wings for genetic tests for two reasons. First, butterflies and moths have nearly 200,000 species, providing an adequate research source. Second Cheap Air Max 95 Online , genetic changes can be discerned in wing patterns.
Martin and his colleagues used CRISPR, a bacterial system that has been likened to cellular cut-and-paste, to delete a gene called WntA in a broad breed of butterflies, The Washington Post reported Tuesday.
The small modification led to big changes. For example Cheap Air Max Online , in Heliconius butterflies, a species with dramatic colors, a large red spill appeared on the wings of the mutant ones.
Other noted changes included color splotches and different tints along the edge of the wings.
"It's extraordinary that it works so broadly," said Owen McMillan Cheap Nike Air Max 97 Wholesale , a staff scientist at the Smithsonian Tropical Research Institute and a co-author of the study.
The researchers knew WntA is important for wing patterns. However, they were surprised that its removal could lead to changes in so many different forms.
The study highlights the flexibility of the evolution regulation. Carolina Concha, a biogenomics researcher at the Smithsonian and another author of the study, called it "extraordinary".

PYONGYANG, Nov. 22 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) on Wednesday slammed the United States for relisting it as a "state sponsor of terrorism Cheap Nike Air Max Wholesale ," calling it a serious provocation and a violent infringement upon the country's dignity.
A spokesman for the DPRK's Ministry of Foreign Affairs said that since 1979, the United States has been labeling the countries that are not obedient to it as "state sponsors of terrorism" and in 1988, Washington listed the DPRK as a "state sponsor of terrorism" before removing it from the list in October 2008.
He said that the label of "state sponsor of terrorism" is just a tool of American-style authoritarianism that can be attached or removed anytime in accordance with the United States' own interests.
"This is clearly an absurdity and a mockery of world peace and security," said the spokesman.
He said the DPRK values international justice and peace and consistently stands against all forms of terrorism and any sponsorship of terrorism.
"We do not have anything to do with terrorism and we do not care whether the United States puts.
