In a series of unusually candid remarks, the US general in charge of the nation's nuclear arsenal has issued a stark warning that Russia and China are "aggressively" developing new high-speed, or hypersonic, weapons that the US currently has no defense against.The weapons might not be operational for several years, but Gen. John Hyten, the four-star head of US Strategic Command, is warning that changes to missile defenses are urgently needed or the US will be unable to detect them when they are operational."China has tested hypersonic capabilities. Russia has tested. We have as well. Hypersonic capabilities are a significant challenge," Hyten told CNN in an exclusive interview. "We are going to need a different set of sensors in order to see the hypersonic threats. Our adversaries know that."Hyten and other military officials say the current generation of missile detecting satellites and radars won't be enough to detect these new generation weapons. Hypersonic is generally defined as a speed of Mach 5 or over 3,806 miles per hour."We've watched them test those capabilities," Hyten told Congress last week. But with unusual public candor about potential US military shortfalls, he acknowledged "we don't have any defense that could deny the employment of such a weapon against us, so our response would be our deterrent force, which would be the triad and the nuclear capabilities that we have to respond to such a threat."Hypersonic missiles fly into space after launch, but then come down and fly at high speeds on a flight path similar to an airplane. Their lower trajectory make them more difficult for US missile defense satellites and radars to detect. Russia has openly stated it is developing high-speed air-launched missiles as well as underwater hypersonic drones.The Pentagon is currently writing a review of its missile defenses to help determine what new capabilities might be needed to deal with new classes of attack weapons. Hyten gave Congress a hint of what may be in that review stating "the first thing we need is better sensor capability, better tracking capabilities to make sure we can characterize and then respond to that threat."He also called for improved US warheads, essentially "better kill vehicles on the top of our interceptors so that those kill vehicles become more and more lethal." The Pentagon is also working on concepts for interceptor missiles that repel a barrage of enemy attack missiles. Current US missile defenses are designed to only shoot down a small number of enemy missiles.The US focus has largely been to work on hypersonic technologies across the board. But Russia is now well into testing some of its systems. Earlier this month Russia showed video of what the Kremlin said was an air-launched hypersonic ballistic missile.When asked how far along the Russian hypersonic program is, Hyten told CNN, "I don't want to put a who's winning the race, I'll just say there is a race."When asked how soon it could be before the Russians have an operational hypersonic weapon that could reach the US, Hyten said, "It's similar to the North Korea problem. If you continue to pursue that technology, you will get there. And the Russians will get there, the Chinese will get there and we'll get there -- and we'll have to figure out how to deal with that." 3323

In a Tuesday morning tweet, President Donald Trump pushed an unfounded conspiracy theory suggesting a 75-year-old protester in Buffalo who was pushed to the ground by police was an "ANTIFA provocateur."In the tweet, Trump claimed 75-year-old Martin Gugino, "was pushed away after appearing to scan police communications in order to black out the equipment."Trump claimed his information came from One America News Network, a conservative news channel known for its favorable coverage of the president. He did not provide a link or a video of the report.Gugino remains in serious but stable condition at Erie County Medical Center. Gugino was part of a group protesting outside of Buffalo's City on Thursday against police brutality in the wake of George Floyd's death. Video from the scene shows police in riot gear shove Gugino out of the way. When an officer offers help him up, another officer appeared to chastise him for doing so. 943

  

In an industry like cosmetology, where all services revolve around hair, skin and nails, getting up close and personal to people is a big part of the job.For those looking to make a career in the beauty business, the pandemic is taking a toll. “I had 84 students pre-COVID,” said Donna Kramer, executive director at Empire Beauty School. “I have 72 right now.”Kramer says COVID-19 initially caused the campus to close.It’s recently reopened with new restrictions set by the local health department. Class sizes are smaller, fewer clients can come in due to social distancing and all students have to wear masks.The area that’s taken the biggest hit, however, is attendance.“It’s kind of toying with people’s personal lives,” Kramer said. “We’ve had students that have had to miss a lot of school because of daycare issues. We’ve had students that have had to actually stay away temporarily because their spouses.”According to the U.S. Bureau of Labor Statistics, employment of hairstylists and cosmetologists is projected to drop by 1% by the end of the decade, which is leaving many students concerned that their career opportunities might be going down the drain.“I know a lot of students kind of have that fear of not being able to find a job now with COVID,” said Alexis Lovato, a cosmetology student at Empire Beauty School.Lovato says many of her classmates are concerned about their employment options once their training is complete.“I think a lot of its just worried about being placed and what’s going to be available for them after their graduation,” she said.Kramer says despite the challenges, students are still getting their hours in and while hands-on training may be a little different, it’s a style they can adapt to.“This industry is going to really flourish once we can get through this,” she said. 1826
