MERRITT ISLAND, Fla. – About 250 miles above earth, the International Space Station remains in constant orbit around the planet.“It's an amazing facility,” said retired NASA astronaut Rex Walheim. “It's about the size of a five-bedroom house.”It’s an incredible feat of construction, involving space agencies from multiple countries and astronauts like Walheim, who flew three missions to the International Space Station.“The first portion of the space station program was basically constructing it,” Walheim said. “So, that was what I was most involved with, bringing pieces of the space station, doing spacewalks to bolt new pieces on and to activate them.”In the now 20 years since the space station welcomed the first crew, it’s become a place of valuable research for companies like Techshot.“The people that make the experimental instruments that go in there are people like Techshot,” said Dave Reed of Techshot.We visited Techshot’s facility near the Kennedy Space Center in Cape Canaveral.Their work on the space station includes measuring bone loss, for use in developing treatments for osteoporosis.“Understanding osteoporosis is obviously of great interest to people on earth,” Reed said. “So, drug companies have been a lot of our customers.”Techshot also created a “bio fabrication facility,” which was installed on the space station.Using stem cells, the machine can 3D print human cartilage, a process that works best in a zero-gravity space environment. The idea is to eventually be able to 3D print whole organs that could be used in transplants.“It’s in the future, but it’s not as far away as you might think,” Reed said.Among the other things the space station astronauts have helped develop for use here on earth are advanced water purification systems, where they recycle 93% of the water on the station. Astronauts on board have also collected valuable data, like visual images, to help support first responders to natural disasters in the U.S. and around the world.Those are advances that might not be possible without the space station.“Young people today have never known a time when there hasn't been humans in space,” Walheim said. “That's really amazing.”It’s a whole generation who see humans living and working in space as an everyday part of life. 2288

Los Angeles-area protests calling for justice for an 18-year-old man shot and killed by police last week ended Sunday when police reportedly fired tear gas and rubber bullets at protesters.Video from Sunday's demonstrations shows police using chemical dispersants and shooting projectiles at protesters in Compton.One protester told CNN that the confrontation escalated into violence when a demonstrator wouldn't "back down" to police.KCBS reports that six people were arrested for unlawful assembly, and one person was charged with resisting arrest.Demonstrators were calling for justice for 18-year-old Andres Guardado, who was shot and killed by Los Angeles County Sheriff's deputies in an alley behind a Los Angeles auto shop on Thursday.Police say Guardado flashed a gun and then fled as officers chased him. CNN reports that a deputy fired six rounds at Guardado. Investigators say they recovered an unregister semi-automatic pistol at the scene that included an illegal extended magazine loaded with live rounds.Guardado's family maintains that he was working as a security guard at the body shop at the time of the shooting, and added that they do not believe he owned a gun. But police officers claim that Guardado was not recognizable as a security guard because he did not have a uniform on and was not wearing a gun belt.California law also requires that security guards be at least 21 years old.Capt. Kent Wegener, the head of the department's Homicide Bureau, says investigators have taken six or seven exterior cameras from the scene of Thursday's shooting. It's unclear if any of the footage contains images of the shooting itself.Guardado's death marked the second fatal shooting by a Los Angeles County Sheriff's deputy in a week. 1756

Marking the breakout of peace after World War I, President Donald Trump on Sunday honored a century-old transatlantic alliance that some fear is fraying.He and dozens of his global counterparts gathered at the Arc de Triomphe in central Paris to mark 100 years since the nightmares of World War I ended, a conclusion brought about partly by the entry of the United States into the bitter, nationalism-fueled conflict.Trump arrived separately from other foreign leaders to Sunday's armistice centenary ceremonies, which occurred under gray skies and cold drizzle. His counterparts, including French President Emmanuel Macron, German Chancellor Angela Merkel and Canadian Prime Minister Justin Trudeau, convened at the élysée Palace before traveling together in motor coaches to the Arc de Triomphe. They walked in a large group to the event site.Trump arrived in his own vehicle and walked in separately. A topless protester breached a police barricade and ran toward Trump's motorcade before being apprehended. Russian President Vladimir Putin also arrived separately and walked in solo. 1095
