Question: Beijing (CNN) China -- North Korea's only global ally and biggest trading partner -- has put on a stoic face since Pyongyang successfully conducted its sixth nuclear test Sunday. President Xi Jinping didn't mention his country's unruly neighbor at all in his closing address at the BRICS summit of emerging economies Tuesday, or in earlier speeches, although a communique issued by the group expressed deep concern and called for the crisis to be settled peacefully. But the test of a hydrogen bomb couldn't have sat well with China's leader. It's the third time in one year that North Korea has overshadowed a major Chinese event -- previous missile tests coincided with the unveiling of Xi's global economic blueprint at his Belt and Road summit in May and the G20, which China hosted last September.Voices in China diverging from official line on North Korea policyNuclear test seen as an embarrassment to Xi JinpingXi makes no reference to North Korea in closing summit speech

Question: The victims of a horrific medical experiment run by the United States in Guatemala that deliberately infected individuals with syphilis in order to test drugs and study the disease are now suing Johns Hopkins University. The lawsuit, which has 750 plantiffs and includes victims and their families, is seeking $1billion, claiming that officials from Hopkins approved the study at the time and even helped to plan and monitor it as it ran from 1945 to 1956. The few victims who are still alive were almost all children when they were unknowingly infected, and many among them were orphans. In the aftermath of the experiment, some of the individuals died of syphilis, with open sores covering their bodies, while those who did survive claim they passed the disease down to their children, ending up with babies that were born blind, severely handicapped, and, in at least one case, without a brain.Victims and their families of a US study that infected individuals with syphilis in Guatemala without their knowledge are suing Johns HopkinsIn a $1billion lawsuit, 750 plaintiffs claim the college approved and helped to plan the study, which ran from 1945 to 1956The victims were mostly orphans, children, prisoners, soldiers, prostitutes and mental patientsMarta Orellana was just 9 years old when one day at the orphanage she was ordered to go to the infirmary and infected with the diseaseFederico Mesa was a solider who was forcibly injected with syphilis as a soldier and passed it along to his familyMarta Ruiz's husband was infected, and she gave birth to one child who did not have a brain and another who is severely handicappedAnother woman, Victoria, claims she was born blind because he father was infectedBlindness, deformities, and death are just some of the problems babies born with congenital syphilis faceA lawyer for Johns Hopkins has called the suit 'baseless'
