A new complaint unsealed Friday revealed extraordinary new details of how Russian trolls manipulate U.S. politics and try to fool unsuspecting Americans on social media.A Kremlin-friendly oligarch has allegedly continued pumping millions of dollars into the St. Petersburg troll farm that was responsible for interfering with the 2016 election.The Justice Department said the Russians "took extraordinary steps" to hide the fact that their controversial posts were coming from foreign meddlers. To make that happen, managers at the troll farm gave employees comprehensive instructions on how to pose as American activists, according to a court filing. Often these directions accompanied real article that the trolls would share, along with their own comments. 767

A van slammed into a crowd Saturday in an apparently deliberate act in the German city of Muenster, killing two people and leaving 20 others injured, officials said.The driver also shot and killed himself, a police spokeswoman said. The driver was a German citizen, said Herbert Reul, state minister for internal affairs in North Rhine-Westphalia state.Authorities are treating the incident as an attack. There is no known connection to radical Islam but investigators are still looking into the driver's background, Reul said.Police earlier said there were three deaths. Reul clarified later Saturday that the total included the attacker.Muenster police spokesman Andreas Bode said law enforcement is looking into witness reports that some people fled the attacker's van after the attack. He also said there was a suspicious object in the vehicle that was under investigation.Bode said the motive of the driver is unknown.The attack happened in the old part of the western German city, an area popular on weekends. It was a warm sunny afternoon, one of the first nice days of spring, and many people were out in the area with its narrow streets, Bild editor Julian Reichelt told CNN.German Chancellor Angela Merkel said she is "deeply shocked by the terrible events in Muenster."In a statement tweeted by German government spokeswoman Ulrike Demmer, Merkel said "everything is now being done to clarify the act and support the victims and their families."The driver drove a vehicle into a restaurant's open terrace around 3:30 p.m. local time, according to police spokeswoman Vanessa Arlt.Arlt said the old city remains closed, and police have asked people to avoid the city center.Muenster, with about 300,000 people, is home to numerous universities and has a student population of about 58,000, the city government says. The city calls itself the cycling capital of Germany and says about 100,000 residents use a bike daily."With dismay, I learned of the terrible incident in Muenster," Interior Minister Horst Seehofer said in a statement, adding, "Police in Muenster and throughout (the state of North Rhine-Westphalia) are now working hard to investigate the matter."Federal authorities are in close contact with local officials, Seehofer said.The White House sent condolences in a statement from press secretary Sarah Sanders."Our thoughts and prayers go out to the families of those killed and we wish a full recovery to those injured. While the German authorities have not yet announced a motive for this cowardly attack on innocent people, we condemn it regardless, and pledge any support from the United States government that Germany may need."Saturday's crash occurred on the one-year anniversary of a similar attack in Stockholm, Sweden, when a stolen beer truck struck pedestrians, killing five people. 2826

A teacher's assistant handbook is causing some controversy at the University of Maryland. The handbook was meant for Computer Science TA's and had separate instructions for both men and women. Now, some people are saying the comments made inside are sexist.It tells the women their students may have trouble accepting they are in the scientific field because it's a male associated activity. The handbook continues to say this is good practice for the real world because students may not be the only ones having trouble accepting women as a professional. 607

A new study takes a look at how deep the problem of plastics in the ocean goes. Studies have looked at the quantity and spread of plastics in the world’s oceans, and now scientists are getting a better idea of how much of that litter is sinking down to the sea bed.The study, from Australia’s national science agency CSIRO, estimates there is 14 million metric tons of microplastics sitting on the ocean floor. That would be more than 35x as much plastic scientists believe is floating on the surface of the ocean.Microplastics are defined as pieces of plastic that have been worn down by the ocean and other elements into tiny fragments, smaller than 5 millimeters.The team collected samples of deep-sea sediments up to 9,800 feet deep from sites around the Great Australian Bight off the coast of South Australia. The robotic submarine took 51 samples.Scientists found an average of 1.26 microplastic pieces per gram of sediment in the samples.Dr. Denise Hardesty, Principal Research Scientist and co-author of the study, said they were "surprised to observe high microplastic loads in such a remote location.""Our research found that the deep ocean is a sink for microplastics," Hardesty said. "By identifying where and how much microplastic there is, we get a better picture of the extent of the problem."Around 150 million metric tons of plastic are already floating in our oceans -- with an additional eight million tons entering the water each year, according to the World Economic Forum.The researchers say most of the plastic dumped into the ocean likely ends up on the coasts, rather than on the ocean's surface or floor.The samples were taken in the spring of 2017; the study was published in Frontiers in Marine Science on Monday. 1750
