The UN reports on its North Korea investigation twice a year and does not usually publicize its findings. The diplomat, however, said that this update would be released to the public on March 16. 195

The transformation of 7% of Scott's DNA suggests longer-term changes in genes related to at least five biological pathways and functions.The newest preliminary results from this unique study of Scott, now retired from NASA, were released at the 2018 Investigator's Workshop for NASA's Human Research Program in January. Last year, NASA published its first round of preliminary results at the 2017 Investigator's Workshop. Overall, the 2018 findings corroborated those from 2017, with some additions.To track physical changes caused by time in space, scientists measured Scott's metabolites (necessary for maintaining life), cytokines (secreted by immune system cells) and proteins (workhorses within each cell) before, during and after his mission. The researchers learned that spaceflight is associated with oxygen-deprivation stress, increased inflammation and dramatic nutrient shifts that affect gene expression.In particular, Chris Mason of Weill Cornell Medicine reported on the activation of Scott's "space genes" while confirming the results of his separate NASA study, published last year.To better understand the genetic dynamics of each twin, Mason and his team focused on chemical changes in RNA and DNA. Whole-genome sequencing revealed that each twin has more than expected unique mutations in his genome -- in fact, hundreds.Although 93% of Scott's genetic expression returned to normal once he returned to Earth, a subset of several hundred "space genes" remained disrupted. Some of these mutations, found only after spaceflight, are thought to be caused by the stresses of space travel.As genes turn on and off, change in the function of cells may occur. 1676

The University of Iowa student was last seen jogging in the small community of Brooklyn, Iowa, about an hour east of Des Moines, according to the Poweshiek County Sheriff's Office.A neighbor's security cameras showed Tibbetts running, as well as the Chevy Malibu in the same area, said Rick Rahn, special agent in charge at the Iowa Division of Criminal Investigation. The footage showed the Malibu driving back and forth numerous times, according to an affidavit.Rivera told police he saw Tibbetts running and "pursued her in his vehicle" while she was running in an area east of Brooklyn, according to the document. Then, Rivera told police he parked the car and started running near her."He actually tells us that he ran alongside of her or behind her," Rahn said during a news conference on Tuesday. "And then, at one point, he tells us that Mollie grabbed ahold of her phone and said, 'You need to leave me alone. I'm going to call the police.' And then, she took off running and he, in turn, chased her down."Rivera told investigators he panicked, became angry and doesn't remember what happened next, according to the affidavit."He tells us that at some point in time, he blacks out," Rahn told reporters.Rivera told officers that he "'blocked' his 'memory' which is what he does when he gets very upset, and doesn't remember anything after that until he came to at an intersection," according to the affidavit.He then drove to a driveway to a cornfield and said he noticed an earpiece from headphones on his lap, according to the affidavit. It was then he realized he had put the woman in the trunk of his car and when he went to the trunk, he "noticed blood on the side of her head," according to the affidavit.He told police he dragged then carried Tibbetts to a secluded location and left her there, covering her in corn leaves, according to the affidavit. Rivera later led investigators to the location.Rahn told reporters he could not release information about how Tibbetts was killed. And the motive also remained unclear."I can't really speak to you about the motive," Rahn said. "I can just tell you it seems that he followed her and seemed to be drawn to her on that particular day and for whatever reason he chose to abduct her."Rivera, an undocumented immigrant, is being held on million cash bail. The US Immigration and Customs Enforcement sent a detainer request to local authorities for Rivera, who is from Mexico, according to an ICE spokesman. 2471
