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 Senate Judiciary Committee has also investigated Russia's role in the 2016 elections -- and any ties with Trump associates. But the GOP chairman of the committee, Chuck Grassley of Iowa, made clear that investigating finances would not be part of the inquiry. 263

The state's Horse Racing Board will decide at its June 11 meeting whether to approve the Del Mar racetrack's plan, which would employ a Friday through Sunday race schedule. 172

The report also shows that more than 87 percent of the state is out of the drought. RELATED: Mega storm could cause billions in damage to California, report showsThough none of San Diego County is currently experiencing drought conditions, the monitor shows that the county is still "abnormally dry."The change happened fairly quickly. A report released on January 1, 2019 shows most of the state experiencing some form of drought. Click here to compare reports from other times. 479
