North Korea Holds Massive Rally as Party Congress Ends
North Korean leader Kim Jong Un presided over massive parade in the center of Pyongyang Tuesday marking the end of the country's ruling party congress during which he solidified his grip on power.
Hundreds of thousands of brightly-dressed North Koreans marched through Kim ll–sung Square. Kim Jong Un watched and waved to the crowd from a viewing balcony high above the square.
The four-day Workers' Party congress -- the country's first in 36 years -- ended Monday after the delegates rubber stamped Kim's "Byongjin" policy of pursuing economic development while simultaneously boosting the North's nuclear arsenal.
The congress also named Ri Yong-Gil, North Korea's former military chief, to a number of senior ruling posts -- just months after South Korean intelligence officials said he had been executed on accusations of corruption and other charges.
Researchers Develop Quicker and Cheaper Zika Test
A team of researchers based at Harvard University say they have developed a testing method that could quickly diagnose Zika virus, and do so basically anywhere in the world.
The Zika outbreak first hit the Western Hemisphere a year. Some 57 countries and territories are now reporting cases of people being infected, most by mosquitos that can carry the Zika virus. Several countries also have reported cases that appear to have spread through sexual contact.
Building on work they did to develop a screening method for Ebola, the researchers led by synthetic biologist James Collins came up with a way to screen blood, urine or saliva for Zika virus.
In a paper published in the journal Cell, they said their method uses paper cards about the size of a human hand. If Zika is present, the card changes color. The testing can produce a result in as little as 30 minutes with the change in color easily visible to the naked eye. An even faster result can be achieved by placing the card in a special reader, the researchers say.
