Abstract

Nanotechnology can improve many physical, chemical, physicochemical, and biological properties of materials, which can be very useful for many industries, including the biomedical, aerospace, textile, cosmetics, manufacturing, oil, agricultural, defense, and electronics industries. However, nanotechnology products (or nanomaterials) can be hazardous because of the way they are manipulated on an atomic scale. Since nanomaterials, such as nanotubes, nanoparticles, nanowires, nanofibers, nanocomposites, and nanofilms, are all new, produced with entirely new manufacturing techniques, there are no specific rules and regulations for them. In the present nanoethics study, we provide a detailed report of the ethical, social, philosophical, environmental, safety, and legal issues surrounding nanotechnology and its products, which can be very useful for the training and protection of students, as well as scientists, engineers, policymakers, and regulators working in the field.

A man went on an early morning shooting spree across two Texas counties Sunday, killing a woman and injuring five other people — one of them the Concho County sheriff — before dying in a shootout with law enforcement, authorities said.
At least nine state and local agencies chased the man — a 23-year-old North Carolina resident whose name wasn't released because his family hadn't been notified — for almost two hours, as he opened fire from his pickup truck on random cars across McCulloch and Concho counties, near San Angelo in central Texas. 
The shooter eventually died in a gunfire exchange with a state trooper and a game warden on a highway north of the town of Eden, the state Department of Public Safety said. That was when authorities discovered that he'd been armed with an assault-style rifle, a handgun and hundreds of rounds of ammunition. 
The victims included Alicia Torres, 41, who was shot to death in her car in the town of Eola, and Concho County Sheriff Richard Doane, who was being treated for non-life-threatening injuries at Shannon Medical Center in San Angelo.
Investigators pieced together this timeline of events:&nbsp,doll accessories;
The gunman first opened fire about 4:30 a.m. local time (5:30 a.m. ET) on a vehicle in the Eden area of Concho County, hitting a woman who remained in Shannon Medical Center on Sunday night. Her conditio
He then made his way to a convenience story in Brady, in McCulloch County, where he shot and injured two people as they sat in their vehicle. They were treated and released.
The gunman then turned around and headed back to Eden, where he fired at another vehicle at about 5:30 a.m. That victim was also treated and released.
Just after 6 a.m., Concho County sheriff's deputies responding to a call of shots fired in Eola found Torres dead in her car.
About 15 minutes later, Doane, the sheriff, caught up with the truck north of Eden on U.S. Highway 83. As state troopers arrived to assist, the suspect fired and wounded Doane.
That started the shootout, with a state trooper and a game warden who'd showed up to help exchanging gunfire with the suspect. The man was shot and died at the scene, authorities said.
No other details were released. Investigators would say only that they were reviewing "multiple crime scenes."

Justin Biebers Dubai Trip Is Not Going Very Well

Justin Bieber seems to get into trouble when he goes overseas. At his concert Sunday in Dubai, a fan was able to bum rush the stage and briefly attack the spritely Canadian singer.

First of all, Bieber was two hours late for the Dubai show, which is becoming a thing with Bieber lately,ball jointed dolls. He's late a lot. But the concert took a dark turn when a crazed fan, perhaps angry for being kept waiting so long, ran onto the stage. The National reports a 19-year-old was able to attack Bieber, though only briefly, while the singer was sitting at the piano singing a ballad before a horde of security guards jumped on the unwanted fan. Beiber was able to escape the scrum with his perfectly sculpted face unscathed. He scampered over to the side of the stage and continued bopping while his security team walloped this poor schmo into submission. Unfortunately, the piano was knocked over during the melee and couldn't be used for the rest of the show.

News of the attack first spread, where else, on social media. Beliebers in the crowd were tweeting about it, and so was investor Chris Sacca. He was able to get some of the scrum captured in this Vine: 

Whoa. Crazy fan tackled @justinbieber and knocked the piano down the stage. Mayhem.vine.co/v/b2uVHAJn0je

That's Bieber on the right side of the stage bouncing hesitantly back and forth while the security team wrestles with the fan by that poor piano.

This kid seems to have the worst luck whenever he leaves North America. First it was German officials taking away his monkey friend (who he eventually didn't reclaim), and now this. The Atlantic Wire has written before about how Bieber needs some kind of parental influence, but that's never going to happen. And it maybe, possibly gets even worse. There's a Reddit thread alleging that Beiber is backstage hiding from authorities because they want to arrest him. Take that with a huge grain of salt, obviously. There were similar reports on Reddit yesterday but the Biebs was never placed in handcuffs. We'll update this space if there's anything to that report. Apparently they're mad about one of Bieber's friends dressing in traditional garb and then behaving like an idiot on stage.
