On social media, Nikolas Cruz did not appear to be a peaceful man. He made quite clear his desire to perpetrate the exact type of violence of which he now stands accused.Before he allegedly committed one of the worst mass shootings in US history at a Parkland, Florida, high school on Wednesday, police officials say Cruz wrote social media posts so threatening he was twice reported to the FBI.He hurled slurs at blacks and Muslims, and according to the Anti-Defamation League, had ties to white supremacists. He said he would shoot people with his AR-15 and singled out police and anti-fascist protesters as deserving of his vengeance. Just five months ago, he stated his aspiration to become a "professional school shooter."Yet on the morning of the massacre, the family that took the 19-year-old into their home didn't notice anything terribly strange about the young man's behavior, the family's attorney said Thursday.The only thing abnormal was that he didn't get up for his adult GED class. Normally, the father would take him to class on the way to work, but when they tried to wake Cruz up Wednesday, he said something like, "It's Valentine's Day. I don't go to school on Valentine's Day," according to the lawyer."They just blew it off," attorney Jim Lewis said. "This is some 19-year-old that didn't want to get up and go to school that day, and (they) left it at that."The family took Cruz in last year after his adoptive mother died. Cruz was depressed, Lewis said. The family's son knew Cruz, so they opened their home, got him into a GED class and helped him get a job at a Dollar Tree, the lawyer said."He seemed to be doing better," Lewis said.Prior to the mass shooting that left 17 adults and children dead at Marjory Stoneman Douglas High School, Cruz had exchanged texts with the son, who was a student there.Lewis characterized the texts as, "How you doing? What's going on? Yo, you coming over later?" That kind of stuff. Nothing to indicate anything bad was going to happen."Cruz had a gun. The family knew that, but they had established rules. He had to keep it in a lockbox in his room. Cruz had the key to the lockbox, the attorney said."This family did what they thought was right, which was take in a troubled kid and try to help him, and that doesn't mean he can't bring his stuff into their house. They had it locked up and believed that that was going to be sufficient, that there wasn't going to be a problem. Nobody saw this kind of aggression or motive in this kid, that he would ever do anything like this," Lewis said. Writing on the wall? 2590

On Monday, the NASA Mars InSight lander survived the "seven minutes of terror" during entry, descent and landing to safely arrive on Mars and took up permanent residence on the Red Planet. Unlike the rovers already on the Martian surface, InSight will stay put during its planned two-year mission.What will the stationary craft do until November 24, 2020?InSight has already been busy. Since landing, it has taken two photos and sent them back as postcards to Earth, showing off its new home. These initial images are grainy because the dust shields haven't been removed from the camera lenses yet.And late Monday, mission scientists were able to confirm that the spacecraft's twin 7-foot-wide solar arrays have unfurled. With the fins folded out, InSight is about the size of a big 1960s convertible, NASA said."We are solar-powered, so getting the arrays out and operating is a big deal," said InSight project manager Tom Hoffman at NASA's Jet Propulsion Laboratory. "With the arrays providing the energy, we need to start the cool science operations. We are well on our way to thoroughly investigate what's inside of Mars for the very first time."The solar arrays are key to helping InSight function. Although Mars receives less sunlight than Earth, InSight doesn't need much power to conduct its science experiments. On clear days, the panels will provide InSight with between 600 and 700 watts -- enough to power the blender on your kitchen counter, NASA said. During more dusty conditions, as Mars is known to have, the panels can still pull in between 200 and 300 watts.Within the next few days, InSight's 5.9-foot-long robotic arm will unfold and take photos of the ground surrounding the lander. This will help mission scientists determine where its will place instruments.This whole unpacking process as InSight settles into its new home will take about two to three months as the instruments begin functioning and sending back data.The suite of geophysical instruments will take measurements of Mars' internal activity like seismology and the wobble as the sun and its moons tug on the planet.These instruments include the Seismic Experiment for Interior Structures to investigate what causes the seismic waves on Mars, the Heat Flow and Physical Properties Package to burrow beneath the surface and determine heat flowing out of the planet and the Rotation and Interior Structure Experiment to use radios to study the planet's core.InSight will be able to measure quakes that happen anywhere on the planet. And it's capable of hammering a probe into the surface.This is why the information InSight sends back about its landing site is crucial. Creating a 3D model of the surface will help engineers understand where to place instruments and hammer in the probe, called the Mars mole HP3 by those who built it."An ideal location for our Mars mole would be one that is as sandy as possible and does not contain any rocks," HP3 operations manager Christian Krause said.Tilman Spohn, principal investigator of the HP3 experiment, said, "our plan is to use these measurements to determine the temperature of Mars' interior and to characterize the current geological activity beneath its crust. In addition, we want to find out how the interior of Mars developed, whether it still possesses a hot molten core and what makes Earth so special by comparison."The first science data isn't expected until March, but InSight will be sharing snapshots of Mars along the way. And InSight's magnetometer and weather sensors are taking readings of the landing site, Elysium Planitia -- "the biggest parking lot on Mars." It's along the Martian equator, bright and warm enough to power the lander's solar array year-round.The information InSight will gather about Mars applies to more than just the Red Planet. It will expand the understanding of rocky planets in general."This has important implications beyond just these two neighbors [Mars and Earth], as we are currently discovering thousands of exoplanets around other stars, some of which may be quite similar to Earth or Mars in terms of size, location and composition," said Jack Singal, a physics professor at the University of Richmond and a former NASA astrophysics researcher. 4251

One of the most anticipated Black Friday ads of the year is finally out.Walmart has unveiled the deals shoppers can snag in its sale, which starts at 6 p.m. on Thanksgiving Day. Unlike Target, Best Buy and Kohl's, where lines form outside the store in advance of the opening, Walmart has taken to scattering its lines inside. That prevents a mob from rushing the doors (we all remember those "Dawn of the Dead"-style videos from past years) and allows shoppers to line up at specific stations inside the store depending on what they are hoping to buy. It also provides a climate-controlled environment for shoppers.The best Walmart deals4KTVs are the hottest Black Friday item for the second year in a row, and Walmart's top doorbusters include a 65-inch Sharp 4KTV for just 8, one of the best prices you will find anywhere for that size.Other big Thursday evening markdowns include Fitbits, smart home devices, iPhones, Beats earbuds and gaming systems, especially the new Nintendo Switch.  Among the hottest deals: 1092

Ohio State's board of trustees is debating the fate of football coach Urban Meyer, who could face disciplinary action over his handling of domestic violence allegations against one of his former assistants.The board of trustees held a meeting private Wednesday to discuss a possible punishment against Meyer.Meyer has been accused of turning a blind eye to alleged domestic violence committed by Zach Smith, his wide receivers coach at both Ohio State and Florida. Smith was fired by Ohio State in late July when his ex-wife filed a domestic violence civil protection order.A day after Smith's firing, Meyer told reporters at Big Ten Media Days in Chicago that he was not aware of any allegations against Smith. Reports later indicate that Meyer's wife and wives of other coaches were aware of the allegations against Smith.Meyer then acknowledged in a statement that he misled reporters about his knowledge of Smith's allegations.  950

OAKLAND, Calif. (AP) — Facebook has banned an extremist anti-government network loosely associated with the broader “boogaloo” movement, a slang term that supporters use to refer to a second Civil War or a collapse of civilization.But the platform didn’t try to name the group, underscoring the difficulty of grappling with an amorphous network linked to a string of domestic terror plots that appears to obfuscate its existence.Facebook designated the movement as a dangerous organization similar to the Islamic State group and white supremacists, both of which it already bans.Facebook says it is removing groups, accounts and pages when they have a “clear connection to violence or a credible threat to public safety.” The company says it has removed 220 Facebook accounts, 95 Instagram accounts and 106 groups that comprise the “US-based anti-government network.”Additionally, Facebook says it has removed 400 groups and over 100 other pages for violating its “Dangerous Individuals and Organizations” policy, because they hosted similar content as the violent network.“So long as violent movements operate in the physical world, they will seek to exploit digital platforms,” wrote Facebook. “We are stepping up our efforts against this network and know there is still more to do.” 1293
