The truck's driver took a turn too tight then sheared a fire hydrant and slammed into a power pole, knocking power lines down in the roadway, MacArthur said. 157

The roses that surround the casket, Owens said, reflected her love for the flower and her propensity to send arrangements "in grand fashion." 141

The three officers were on their way to another incident when they spotted a parked car on fire in the 1500 block of K Street at around 1:45 a.m. Tuesday. 154

The shaking was reported at 5:42 a.m., according to a computer-generated message from the U.S. Geological Survey.The epicenter of the quake was about 5 miles from Valencia, 9 miles from Stevenson Ranch and 10 miles from Santa Clarita, the USGS said. 249

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
