It's amazing how quickly technology can change. What seemed impossible just a few years ago is now reality. Robots are about to reach the next level, flexing their muscles like never before.It may not seem like much in this basement lab, but with a jolt of electricity, a team is creating the muscle of the future. "It's actually one of the closest analogs to natural muscle," says University of Colorado Boulder PhD student Shane Mitchell. "It almost performs like natural muscle."It's delicate enough to pick up a raspberry without bursting it, and an egg without breaking it. Yet strong enough to lift a gallon of water."We were inspired to create this artificial muscle from the world we live in," says Tim Morrissey, who manages the team at the Keplinger Research Group lab. The team develop HASEL, an artificial soft muscle that could enhance robot technology, making them better able to help people who need it."The robot needs to come into your home and work around you," Morrisey says. "And so if the robot is going to go up stairs it's going to need muscles to do that."HASEL muscle technology could also lead to advanced prosthetics.Morrisey says, "If you make a robot that has you know a skeleton frame with a soft bicep on it that moves up and down, you can do the same thing with a prosthetic."While other artificial muscles can be bulky, or unable to withstand electric pulses,  if there's an electric surge, HASEL can even repair itself. And with a rubber shell, electrodes and liquid inside, can you believe it costs only about 10 cents to make. "Originally we used canola oil actually just from the local grocery store," Mitchell says. It's an exciting innovation, but to this team, it's much more."We want to do something new in the scientific community," Mitchell says. "But it's really no help if it just stays in the lab. So we want to bring our technology to the community." Creating the next generation of robot technology, by adding a more natural touch. 2017

It’s the classic vision of Election Day – head to your polling place, check in and vote.But this year, the tradition at the base of our democracy will look very different. Ballots will arrive in the mail for more people than ever due to the pandemic.So, how does the process work? It’s streamlined and closely monitored.You, a voter, get your ballot in the mail. You fill it out and seal it in the provided envelope. It’s crucial you don’t forget to sign in the designated area.From there, you can add postage and drop it in the mail. Some cities have ballot drop boxes that go directly to the county with no stamp or post office needed.Once the state has your ballot, it goes through different stations where independent workers open the envelope, scan the ballot, and check to make sure everything is valid. That process is often open for public viewing, either in-person or streaming online.While that’s meant to provide some transparency, mail-in voting is new to millions of people and some worry it’s not safe and secure.The head of the Federal Election Commission recently tried to put worries at bay. She is quoted as saying “there’s simply no basis for the conspiracy theory that voting by mail causes fraud.”And the statistics back that statement up. The Heritage Foundation, a conservative think tank, found 143 voter fraud convictions out of 250 million mail-in ballots cast since 2000. That works out to about eight cases per year, nationwide.If you are voting by mail, there are three easy ways to make sure your ballot counts.1. Fill it out properly. Don’t go outside the lines or make any stray markings on the ballot.2. Sign your envelope and make sure the signature matches what you have on file.3. And vote early. Experts say it’s the best way to make sure your vote counts. 1801

In late September, after racist slurs were found on the message boards of five black cadet candidates at the Air Force Academy Preparatory School, the school's superintendent was angry.Lt. Gen. Jay Silveria told cadets to line up and pull out their phones to remember his message, and he forcefully denounced racism and intolerance."If you're outraged by those words, then you're in the right place. That kind of behavior has no place at the Prep School," Silveria said.The speech was posted on Air Force Academy's Facebook page and quickly went viral. The Air Force launched an internal investigation to find the culprit.But on Tuesday, Air Force Academy officials said that one of the black cadet candidates actually wrote the racist messages."We can confirm that one of the cadet candidates who was allegedly targeted by racist remarks written outside their dorm room was actually responsible for the act," the Academy said in a written statement. "The individual admitted responsibility and this was validated by the investigation."The vandalism was written in black marker on a dorm whiteboard with the phrase "go home (expletive)."Lt. Col. Allen Herritage, director of public affairs with the Academy, said that the cadet responsible admitted his guilt when confronted. The individual has "received administrative punishment" and is no longer at the preparatory school, Herritage said.The four other students that were the target of the vandalism are still at the Prep School, which is on the same campus in Colorado Springs, Colorado, as the Air Force Academy. The Prep School helps ready about 240 cadets each year to enter the academy.'This is our institution'Silveria, the Academy's superintendent, made clear in his speech in September that there would be no tolerance for racist rhetoric at the Academy."If you can't treat someone from another gender, whether that's a man or a woman, with dignity and respect, then you need to get out," he said. "If you demean someone in any way, then you need to get out. And if you can't treat someone from another race or different color skin with dignity and respect, then you need to get out.""This is our institution, and no one can take away our values," Silveria added. "No one can write on a board and question our values. No one can take that away from us."Although the hateful graffiti was revealed to be a hoax, the Air Force Academy affirmed that same message of dignity respect in a statement on Tuesday."Racism has no place at the Academy, in any shape or form. We will continue to create a climate of dignity and respect for all, encourage ideas that do so, and hold those who fail to uphold these standards accountable."Silveria said in a statement on Tuesday that his speech remained relevant despite the investigation's outcome."Regardless of the circumstances under which those words were written, they were written, and that deserved to be addressed," he said. "You can never overemphasize the need for a culture of dignity and respect and those who don't understand those concepts aren't welcome here."The-CNN-Wire 3091

It started six years ago. And hopefully, it will be the last time in 2020. Please switch on two-factor authentication on all of your accounts. ??— Victor Gevers (@0xDUDE) October 22, 2020 201

In the 45 weeks since the year began, 43 law enforcement officers across the US have been shot and killed in the line of duty, including a sheriff's deputy responding to a mass shooting at a bar in California this week.The parameters CNN followed in this count are: 273
