Question: Students mourn during a candlelight vigil for victims of yesterday ’ s shooting at nearby Marjory Stoneman Douglas High School in Parkland   Fla . on Feb . 15 . ( Reuters / Carlos Garcia Rawlins )  Sixteen - year - old Colleen Lance ’ s English class  spent much of  its  time on Thursday talking about what to do in case someone started shooting . “ Do we try to barricade the door ? Do we try to escape ? What are we supposed do during a shooting ?” she and her fellow students asked their substitute teacher . Lance ’ s classroom in Illinois was a thousand miles from Marjory Stoneman Douglas High School   where a gunman opened fire on Wednesday and killed at least 17 people . But the news hit close to home . “ After Florida   we were all definitely like   ‘ Oh   God   is this going to happen here ?’ ”  Lance  said . “ It ’ s very anxious to go to school after a school shooting . It makes you more aware that you ’ re not safe .”  Lance  wasn ’ t alone in her anxiety . After the latest school shooting   this time in Parkland   Fla .  teenagers across the country returned to their own high schools Thursday for another normal day . But then again   Wednesday had started out as a normal day for Marjory Stoneman Douglas High School . And it was hard not to think about that . Several students responded to a request from The Washington Post via Snapchat to talk about how the news of the tragedy weighed on them as they returned to their own classrooms . ( The Post spoke with some of those students by phone   and contacted their schools to verify their identities and attendance .) [ A loud   new voice after the latest school shooting : Kids wanting to know why adults hadn ’ t done more ] “ It makes me feel really concerned . It feels so much more common now  ” said Rebecca Connor   15   who attends high school in Virginia . “ You don ’ t know where it ’ s going to happen next . It could happen at our school . There ’ s no way to tell .” She added that report after report of troubled students turning on their classmates “ makes me want to be nicer   makes me want to take everyone ’ s feelings into account .” This type of response isn ’ t limited to high school students   said Robin Gurwitch   a psychologist at Duke University Medical Center . But teenagers are particularly vulnerable . “ With teens   the more stressed they are about these events   the more likely they are to have sleep problems   difficulty concentrating and irritability . It can affect school performance and relationships with peers  ” Gurwitch said . For some   the overwhelming sensation wasn ’ t fear but weariness . “ It ’ s become such a common occurrence that it ’ s hard to have a reaction at some point  ” said Aidan McGahey   15   who attends high school in Philadelphia . McGahey said his fellow students sometimes talk about shootings in the immediate aftermath   and that his religion class had tackled the subject this week . Lance dissected the news with her friends   who are similarly interested in keeping up with current events and fall on both sides of the political divide . Connor   a budding news junkie who watches “ Morning Joe ” and keeps up to date with Apple News   confessed that she and her friends didn ’ t discuss school shooting stories much because it would “ make it feel more real .” Gurwitch said that taking time away from the news was critical for teenagers when a story like the Parkland massacre is dominating headlines . She emphasized activities like reading   sports   listening to music   or other activities that allow people to avoid social media or the news for a set period of time . The American Psychological Association has issued similar guidelines for people of all ages dealing with stress related to school shootings in the news . [ We ’ re used to experiencing mass shootings online . But Parkland brought us into the classroom . ] It ’ s not uncommon for schools to have lockdown drills or add security systems to protect students in the event of an attack . But in addition to physical security measures   Gurwitch said   schools should allow discussions about traumatic events “ in a smaller group   so if there are concerns   [ students ] feel comfortable asking a question or commenting on something they may have heard .” No matter how many safe spaces schools create   the teenagers expressed frustration at the recurring issue of school shootings . “ It ’ s not something we can sit back and say   ‘ it ’ s a part of our society ’. We need to be taking active steps to resolve  ” McGahey said . “ I think we need to work to stop this .” “ It makes me upset that it ’ s something I do have to think about . I just want to focus on my grades and graduating and going to college and becoming a young adult  ” Lance said . “ I don ’ t want to think about getting shot when I go to school .”

Answer: 'Is this going to happen here?': After Florida shooting teens worry about their safety at school


Question: Chins in and chests out  the cadets were flanked by 1 500 officers  sergeants  athletic coaches and civilian professors inside cavernous Mitchell Hall.  Lt. Gen. Jay Silveria  told them to take out their smartphones and record  his  words.
"If you can't treat someone with dignity and respect  then get out "  he  said.
 Silveria  spoke as investigators interviewed cadet candidates at the prep school  where five black students woke up Tuesday to find "Go Home" followed by the epithet scrawled on message boards outside their rooms.
After the speech   Silveria  said  he  thinks dealing with the racial slurs in public is important.
"I wanted to make it clear  this is not something I am keeping from anyone "  he  said. "We have to talk about what that means."

Question: "I'm still kind of in shock " says Edward Geist  a researcher specializing in Russia at the Rand Corp. "My guess is they're not bluffing  that they've flight-tested this thing. But that's incredible."
The U.S. did go on to investigate the idea of a nuclear-powered missile   Geist  says. Known as the Supersonic Low Altitude Missile  the idea was more like a nuclear-powered drone aircraft. "It was actually supposed to fly around autonomously and drop nuclear gravity bombs "  Geist  says.
The nuclear reactor that would keep SLAM aloft would also spew radioactive exhaust   Geist  says. At the time  that was advertised as a feature  not a bug  because it would have had the added benefit of polluting the Soviet countryside.
"It was supposed to be really  really dirty "  Geist  says.
The U.S. got as far as actually building the nuclear engine for Project Pluto  a development project at the Nevada Test Site. The reactor was tested a number of times in the early 1960s  and it performed well. But by that point  awareness had grown about the dangers of nuclear fallout  and arms control treaties were coming into place   Geist  says. Those concerns were among the reasons the project died in 1964.
The type of reactor used in Project Pluto was particularly messy because it exposed the nuclear fuel directly to the outside air.  Geist  says the new Russian missile may use a different system that keeps the fuel somewhat isolated from the air. But   he  quickly adds  that wouldn't make it safe.
"There are a bunch of different ways to do it  and frankly  they're all terrible "  Geist  says.
 He  suspects that the Russian design would involve what's known as a "fast reactor " which is more efficient  but also less safe  than most nuclear reactors. If the missile crashed or the reactor failed  it would trigger a major incident.
"It's just crazy they field-tested this thing "  he  says.
 Geist  says  he  expects Russia's provocations to continue. "They're sending us a message that they are not OK with our U.S. missile defense posture "  he  says.
That message? "They're willing to go full Strangelove on us "  Geist  says.
