The Cybertruck has arrived and it looks nothing like any pickup truck you've ever seen. Years after first saying it was on the way, Tesla finally revealed the electric pickup truck at its Design Studio in Hawthorne, California, just outside Los Angeles.When the truck initially drove onto the stage, many in the crowd clearly couldn't believe that this was actually the vehicle they'd come to see. The Cybertruck looks like a large metal trapezoid on wheels, more like an art piece than a truck.Instead of a distinctly separate cab and bed, the body appears to be a single form. The exterior is made from a newly developed stainless steel alloy, Musk said, the same metal that's used for SpaceX rockets. That alloy enables the car to be "literally bulletproof" against, at least, smaller firearms, including a 9 millimeter handgun, Musk said.A man with a sledgehammer hit the sides of the truck without damaging it. But a demonstration of the truck's supposedly unbreakable metal glass windows backfired when a metal ball thrown at the windows did, in fact, break them."But it didn't go through, " Musk sheepishly pointed out.Incredible power at an incredible priceMusk has made striking claims about the truck's capabilities. Among them, he has said the Cybertruck would be more capable, in terms of towing and hauling, than a Ford F-150 and perform as a 1368

The Defense Department has decided not to proceed with three border wall projects in California and Arizona, citing "insufficient contract savings," according to a court filing.The move appears to be a setback for President Donald Trump, who has sparked controversy for dipping into Pentagon funds to build his signature border wall, though it's unclear what will happen to the projects listed in the filing.Last month, Secretary of Defense Mark Esper approved an additional 20 miles of 30-foot-high barriers for the southern border using .5 billion in funds redirected from a counter drug account, which is authorized to spend money on border barrier construction for the purpose of blocking "drug-smuggling corridors."Although then-acting Defense Secretary Patrick Shanahan had earlier approved some 135 miles of fencing requested by the Department of Homeland Security in the Yuma, El Paso and Tucson sectors, the cost of constructing that section of the border wall was less than originally anticipated, freeing up funds to support the additional 20 miles approved by Esper.The Pentagon notified the court of the additional miles at the time, noting the Army Corps wouldn't know the exact amount of savings to move forward with the projects until later in the fiscal year.Monday's court filing, however, reveals that there were not enough funds to cover the costs of the projects."Based on its work in definitizing the contracts for the original Section 284 projects, [the Army Corps] has determined that there are insufficient contract savings to undertake the three additional Section 284 projects authorized by the Secretary of Defense on August 26, 2019," the filing reads. "Therefore, the Department of Defense has decided not to pursue Yuma Sector Projects 4 and 5, and Tucson Sector Project 4 at this time."The President's decision to tap into Pentagon funds for his wall has been legally challenged by the Democratic-controlled House and advocacy groups.In July, the Supreme Court cleared the way for the Trump administration to use .5 billion from the Defense Department to construct parts of a wall along the southwestern border that the government argues is necessary to protect national security.The decision allows the Defense Department money to be spent now while a court battle plays out over whether the government had the authority to divert funds that were not appropriated for the wall.The administration is using funds appropriated for the wall, as well as Defense Department funds, to fulfill the President's pledge to erect new barriers along the southern border. As of August 23, the administration has updated roughly 60 miles of wall on the US-Mexico border, according to Customs and Border Protection and the Army Corps. Construction activities to mount new wall in the Rio Grande Valley sector is underway, according to the agencies. 2881

The days of passengers bringing rabbits, turtles and birds on planes as emotional-support animals could be ending. The U.S. Department of Transportation on Wednesday proposed that only specially trained dogs qualify as service animals, which must be allowed in the cabin at no charge.Airlines could let passengers bring other animals on board, but hefty fees would apply. Airlines have complained that some passengers try to get their pets on board for free by claiming they need them for emotional support under the current rules. 543

The Food and Drug Administration said on Wednesday that some people and companies are trying to profit from this pandemic by selling unproven and illegally marketed products that make false claims, such as being effective against the coronavirus.The FDA says that products that claim to cure, treat, or prevent COVID-19 haven't been evaluated by the FDA for safety and effectiveness, and calls said products "dangerous."Wednesday's announcement comes two weeks after the FDA previously announced it sent letters to a number of companies that sell products that allegedly claim to treat or prevent coronavirus. Simply put, if there are any products that claim to treat or cure coronavirus, the FDA says not to buy it."The FDA is working with medical product developers to rapidly advance the development and availability of vaccines and treatments for COVID-19. Although there are investigational COVID-19 vaccines and treatments being studied in clinical trials, these products are in the early stages of development. They haven't yet been fully tested for safety or effectiveness, or received FDA approval," the FDA said on Wednesday,' the FDA said. The FDA is requesting the public to report suspected fraud to the FDA's 1235
