PROBLEM: Hong Kong (CNN) -- The naughty step is not working. After the United Nations slapped tougher sanctions on North Korea after its third nuclear test in February this year, Pyongyang screamed in defiance. It canceled its hotline with South Korea, withdrew its workers from the Kaesong industrial complex it jointly operates with Seoul, and carried on with its over-the-top threats. China may have backed those sanctions but the economic lifeline is still there. Trade goes on between North Korea and China. In 2011, before some of these trade embargoes began, China accounted for an estimated 67.2% of North Korea's exports and 61.6% of imports, according to the CIA World Factbook.Pyongyang reacted angrily to tougher sanctions after its third nuclear testChinese trade with North Korea has been a lifeline for the isolated regimeBut Beijing has struggled to control the angry rhetoric from its neighborExpert: China fears a North Korean collapse would spark a refugee crisis

PROBLEM: (CNN) For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to come. Researchers had known that seven planets were orbiting the star. But Google Artificial Intelligence -- which enables computers to "learn" -- looked at archival data obtained by NASA's planet-hunting Kepler telescope and uncovered the eighth planet. With the idea of eventually differentiating among exoplanets, Christopher Shallue, senior software engineer at Google AI in California, and Andrew Vanderburg, astronomer and NASA Sagan postdoctoral fellow at the University of Texas, Austin, trained a computer how to differentiate between images of cats and dogs.For the first time, eight planets have been found orbiting Kepler-90It is tied with our solar system for a star hosting the most known planets
