The stabbing was reported Sunday afternoon in the courtyard of an apartment complex in Lewisville, about 20 miles northwest of Dallas. Lewisville Police Capt. Jesse Hunter says the toddler was rushed to a hospital but later died from his wounds. 245

The US Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA) each issued an emergency airworthiness directive on Friday requiring airlines to perform an ultrasonic inspection of certain CFM56-7B engines within 20 days.The FAA and EASA directives came on the same day that the engine manufacturer, CFM International, issued a service bulletin recommending the CFM56-7B engine be inspected more frequently."CFM recommends ultrasonic inspections within the next 20 days to fan blades of CFM56-7B engines with more than 30,000 cycles since new," it said. "Also, it recommends inspections by the end of August for fan blades with 20,000 cycles, and inspections to all other fan blades when they reach 20,000 cycles."After reaching a certain age, the engines should be inspected approximately every two years, the manufacturer said.According to CFM International, about 680 engines will be impacted by the order to inspect engines with more than 30,000 cycles within the next 20 days. More than 150 of those have already been checked by operators, it said.Another 2,500 engines will be impacted by the recommendation to inspect fan blades with 20,000 cycles by the end of August, CFM International said. A jet engine cycle comprises an engine start, takeoff and landing, and full shut down."The inspection, conducted on-wing with an ultrasonic probe along the surface of the fan blade, takes about four hours per engine," the manufacturer said.US federal safety investigators have said the naked eye cannot detect the cracks and signs of metal fatigue that doomed the engine on Southwest Flight 1380.  1627

The public was asked for information about his identity and the California Highway Patrol warned that he was considered armed and dangerous. 140

The victim was sent to the hospital with critical injuries. As of Friday morning, his condition is improving, an attorney representing the family said.  162

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
