A federal judge rejected a challenge to the Trump administration's ban on bump-fire stocks Monday.United States District Judge Dabney L. Friedrich ruled against the plaintiffs in two consolidated federal lawsuits challenging a nationwide ban on the devices and asking for an injunction to prevent the ban from going forward and being enforced.Bump-fire stocks came under scrutiny following a deadly 2017 massacre in Las Vegas, in which a gunman rigged his weapons with the devices to kill 58 people and injure nearly 900. The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) responded, in part, by reconsidering its definition of machine guns to include "bump-stock-type devices."Bump stocks, also known by the brand name Slide Fire, modify rifles, 771

A California man was arrested over the weekend after allegedly making a mass shooting threat to get out of going to a county fair with his parents, authorities said Saturday.According to the Pomona Police Department, Erik Villasenor emailed the Los Angeles County Fair staff on Friday afternoon and made false threats of violence.Pomona Police Chief Mike Olivieri said the email read, "Hello I was told that someone was planning on doing a mass shooting on Sunday at the fairgrounds. I just wanted to inform you guys already."The Sylmar, California, resident was suppose to go to the fair with his parents Sunday, Olivieri said at a press conference. Investigators believe he sent the threat in order to get out of going to the event with his family."Though he's 22, he felt it was appropriate to send this threat ... we believe it was with the intent it would spark some chaos and commotion, be captured on the media, and use it as an excuse to his parents to not go to the fair," Olivieri said at the Saturday press conference.Villasenor admitted it was a hoax when authorities tracked him down, police said."This is a great outcome for the fair and it really provided us an opportunity to test the kind of security systems we have worked so hard to create," said Miguel Santana, the president and CEO of Fairplex, the venue where the fair is held.Villasenor was arrested on a charge of making false threats and was booked at the Pomona County Jail. His bail is set at ,000.According to inmate information from the Los Angeles County Sheriff's Department, Villasenor has a court date set for Tuesday. 1617

A Japanese space probe has successfully fired a "bullet" into an asteroid as part of a mission to collect rock samples from the celestial body.The projectile disturbed material from the exterior of asteroid Ryugu which then floated from its surface due to the weak gravitational field.These particles were successfully collected by the probe, according to Japan's space agency JAXA, which announced that the Hayabusa 2 craft had successfully touched down on on the asteroid on Friday morning Japanese time.JAXA scientists had expected to find a powdery surface on Ryugu, but tests showed that the asteroid is covered in larger gravel.As a result the team had to carry out a simulation to test whether the projectile would be capable of disturbing enough material to be collected by what scientists call a "sample horn," which protrudes from the underside of the probe.This video shows the success of a December 28 test, which green-lit the asteroid landing.The team is planning a total of three sampling events over the next few weeks.Hayabusa 2 will depart Ryugu in December 2019 and return to Earth by the end of 2020 with its precious cargo of samples, which will be analyzed by scientists such as John Bridges, a professor of planetary science at the University of Leicester, UK.Bridges, who was also involved in the first Hayabusa mission, told CNN via telephone on Thursday that the event was "nail-biting stuff" due to the extreme precision involved in landing on Ryugu."This is a significant mission," said Bridges. "Sample return missions are particularly exciting."He told CNN that the Hayabusa 2 mission is interesting because Ryugu is a C-class asteroid which humans haven't visited before."One thing I'm pretty sure of is that it will throw up some unexpected results," said Bridges, who believes that information from Ryugu samples could make us think again about the early evolution of the solar system.Beneath their desolate surface, asteroids are believed to contain a rich treasure trove of information about the formation of the solar system billions of years ago.C-type asteroids, which are largely composed of carbon, are the most common variety of asteroids, comprising more than 75% of those currently discovered. The other two main types of asteroid are the metallic S- and M-types, according to NASA.Ryugu is expected to be "rich in water and organic materials," allowing scientists to "clarify interactions between the building blocks of Earth and the evolution of its oceans and life, thereby developing solar system science," JAXA said.If Hayabusa 2 makes it back to Earth on schedule it will be the first mission to bring back samples from a C-class asteroid.JAXA scientists are currently racing NASA for that historic achievement, with the US agency's own sample retrieval mission due to arrive back on Earth in 2023.Even reaching the asteroid is a massive achievement as it is the equivalent of hitting a 6-centimeter (2.4-inch) target from 20,000 kilometers (12,400 miles) away."In other words, arriving at Ryugu is the same as aiming at a 6-centimeter target in Brazil from Japan," said JAXA.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company.

A Kingman animal hospital helped deliver 19 Great Dane puppies from one mother on Saturday morning. Kingman Animal Hospital says all of the puppies were delivered successfully, and are alive and healthy. The mother dog was also doing well after the C-section. Eleven staff members at the animal hospital helped perform the surgery and checked the puppies afterward for any issues. “Thank you all for the kind words and congrats to the momma dog and our hard working staff that came in for this emergency,” their Facebook post read. 544
