PROBLEM: (CNN) Video appears to show children gathered around someone handing out sweets moments before Saturday's suicide vehicle bombing that killed dozens of evacuees from besieged Syrian villages, the UN's human rights agency said Tuesday. The agency didn't give further details about the footage, such as whether it shows the explosion in Rashidin, a suburb of Aleppo in northwestern Syria. But the statement fits with other reports, including one from a witness who said many of those killed or injured in the attack were children who were picking up handout snacks. No one has claimed responsibility for the blast, in which 126 people -- including 68 children -- were killed, according to the Syrian Observatory for Human Rights monitoring group. Dozens of others were injured, according to Syria Civil Defense, the volunteer rescue groups also known as the White Helmets.Explosion hit people who were leaving their towns on SaturdayThe attack killed 126 people, including 68 children, monitoring group says

SOLUTION: The explosion happened outside a line of parked buses that were evacuating hundreds of people from two regime-held but rebel-besieged villages in northwest _.

PROBLEM: Cairo (CNN) -- The much anticipated trial of former Egyptian Interior Minister Habib El Adly has been postponed until August 3 -- the same day Egypt's ousted president is scheduled to stand trial. El Adly and former Egyptian President Hosni Mubarak face charges of killing pro-democracy protesters during the revolution that started six months ago. El Adly's trial at a Cairo court was expected to be carried live on state television Monday. This is second time the trial was postponed amid frustrations among protesters in Tahrir Square who demand speedy trials and swift judgments for detained officials from Mubarak's regime.Former Egyptian Interior Minister Habib El Adly faces charges of killing protestersHis new trial date is the same day as ousted President Hosni Mubarak's trialProtesters are angry after demanding speedy trials and swift judgments on regime membersSix of El Adly's former assistants are also accused of killing protesters

SOLUTION: _ appeared with a blue uniform because he had been sentenced to 12 years for corruption charges.

PROBLEM: (CNN) Nearly everyone carries one version or another of the herpes virus. A recent study suggests that the new gene-editing technology known as CRISPR/Cas9 may be able to eliminate this ever-present virus -- or at least suppress it. "At this point, there is no cure for the herpes virus infection. Once infected, you're infected for life," said Robert Jan Lebbink, co-author of the study and a molecular biologist at University Medical Center in Utrecht, Netherlands. The virus develops a latent stage, in which it lies dormant in an infected cell without reproducing. Because our immune systems cannot recognize latent infections, we cannot clear them from our bodies.Only eight of more than 100 herpes viruses routinely infect humansTested in a petri dish, CRISPR gene-editing technology eliminated some strains

SOLUTION:
So, while it appears the _/Cas9 system may be very effective in rooting out herpes, Lebbink explained that much more research is needed.
