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 may be a job most people do not think about regularly, but one man in Nashville, Tennessee is being honored for his efforts to do it well: Herman Patton is a greeter for Alamo Rental Car.Patton des his part in a huge piece of Nashville's tourism economy, which raked in more than billion last year.According to the Nashville Convention and Visitor’s Corp, most of the 14 million people who visited the city last year said they would come back to Nashville.Nashville is at the top of friendly city lists across the world, and the Convention and Visitor’s Corp is saying thank you to the city's hospitality workers who make that happen with an honor called the Hitmaker Award. 693

It's often referred to as "The most exciting two minutes in sports."So what makes the Kentucky Derby so special?Here are five reasons not to miss the event, which will be held on May 5 at Churchill Downs race track in Louisville, Kentucky.It's America's longest running sports eventThe first Kentucky Derby was held on May 17, 1875, when a crowd of 10,000 saw three-year-old chestnut colt Aristides, ridden by African-American jockey Oliver Lewis, triumph at Churchill Downs.The Derby has been held at the same venue ever since, even during both World Wars and the Great Depression of the 1930s, making it the country's longest continuously held sports event.The 144th edition of the mile-and-a-quarter race for three-year-old thoroughbreds is expected to attract more than 150,000 spectators.The Derby is the first leg of racing's prestigious Triple Crown, which also consists of the Preakness Stakes in Baltimore and the Belmont Stakes in Belmont Park, New York.READ: No touchdown in Kentucky for Gronkowski...the horseIt has literary historyThe Kentucky Derby has been covered by some of America's most famous writers.In 1925, New York sports columnist Bill Corum called the Derby the "Run for the Roses" because the winning horse gets draped in a garland of hundreds of red roses.In 1935, legendary Tennessee-born sports writer Grantland Rice described the race like this:"Those two minutes and a second or so of derby running carry more emotional thrills, per second, than anything sport can show."His phrase has since been shortened to describe the Derby as "the most exciting two minutes in sports" or "the greatest two minutes in sports."In 1955, American author William Faulker, a winner of the Pulitzer Prize and Nobel Prize and a Southerner like Rice, covered the race for Sports Illustrated.This what he wrote:"So it is not just betting, the chance to prove with money your luck or what you call your judgment, that draws people to horse races. It is much deeper than that. It is a sublimation, a transference: man, with his admiration for speed and strength, physical power far beyond what he himself is capable of, projects his own desire for physical supremacy, victory, onto the agent -- the baseball or football team, the prize fighter. "Only the horse race is more universal because the brutality of the prize fight is absent, as well as the attenuation of football or baseball -- the long time needed for the orgasm of victory to occur, where in the horse race it is a matter of minutes, never over two or three, repeated six or eight or 10 times in one afternoon." It has legendary winnersIn 1973, Secretariat won the Derby in a time of one minute, 59.4 seconds, a record that still stands to this day. By comparison, last year's race was won by Always Dreaming, ridden by jockey John Velazquez, in a time of two minutes 3.59 seconds.Secretariat, also known as "Big Red," went on to clinch the Triple Crown in 1973, ending a 25-year wait.In 2006, Barbaro captured the public's imagination with an epic Derby win followed by a heroic fight against injury. After becoming only the sixth horse to win the Derby with an unbeaten record, Barbaro looked like he could be on the way to the Triple Crown when disaster struck in the Preakness Stakes two weeks later -- he shattered his leg shortly after getting out of the starting gates.Barbaro was put down by his owners eight months later, unable to overcome the complications he had suffered after the accident.But his fight to overcome his injury triggered an outpouring of public support for the horse and his owners the world over. His ashes are now buried at Churchill Downs, while a bronze statue of the horse was erected at the race track in 2009.In 2015, American Pharoah became the first horse to win the coveted Triple Crown since Affirmed in 1978. The horse made the cover of Sports Illustrated and was photographed by US fashion magazine Vogue.It attracts the rich and famousThe Derby has always been a draw for the rich and famous, with some of the biggest stars in sports, fashion and Hollywood mixing with royalty.Previous Derby guests include Britain's Princess Margaret, boxer Muhammad Ali, US presidents Lyndon B. Johnson and Richard Nixon, Hollywood legends Lana Turner and Bing Crosby, baseball star Babe Ruth and in recent years, singer Justin Timberlake, actor Jack Nicholson, Britain's Queen Elizabeth II and NFL star Eli Manning.The favorite tends to do wellLast year's win by Always Dreaming marked the fifth year in a row the pre-race favorite had won the race, the most since the 1890s.If you fancy a punt, this year's Derby looks like a very open race, with Justify, trained by American Pharaoh's handler Bob Baffert, heading the betting ahead of Aidan O'Brien's Irish raider Mendelssohn.No European horse has ever won the Kentucky Derby.The-CNN-Wire 4850

In many ways, we have come a long way since March when the pandemic first began, but in other ways, we have not.Infections and hospitalizations around the country from COVID-19 are rising quickly, as the United States just surpassed 250,000 deaths from COVID-19. The country is also setting records for the number of positive coronavirus cases. It has forced states to consider similar shutdown measures to the ones we saw in spring.Michigan, Washington state, Oregon, and New Mexico are mostly closed, as states like Colorado have recently announced more closures coming this weekend, including moving restaurants to take-out and delivery only.“It has been very busy [in the ICU] and it has really, as you mentioned, gone up in the last two weeks,” said Dr. Julia Limes of UCHealth in Colorado.Dr. Limes has been spending the last few weeks working out logistics for the ICU at the University of Colorado Anschutz Medical Center.“We have started deploying people from other parts in the hospital to come and help us on both the COVID floors and in the COVID ICU,” said Dr. Limes.“We already surpassed the numbers from the first surge, so it’s like what’s next?” added Maddie Smith, a critical care nurse in the hospital’s COVID-19 ICU.Smith has worked in the hospital’s COVID-19 ICU since March. She says the fear, stress, and unpredictability of this current surge might have consumed her once more if it was not for the lessons learned in the COVID-19 unit during the spring months.“We just know how to treat them better, and we know how to intervene with interventions, so that’s been really helpful,” said Smith.In the spring, hospitals were experimenting with different drugs to treat serious COVID-19 complications. Since then, the FDA has approved Remdesivir as a treatment option for certain patients 12 and older, based on findings that it helped some patients recover faster.Smith says doctors and nurses are now more familiar with the arc of how a patient might respond to symptoms so they can manage bed space and ventilator use better.All this comes as both Moderna and Pfizer announced this week they have both developed vaccines with 95 percent effectiveness.“[Caring for patients] is easier and it’s smoother than it was in the spring,” said Dr. Limes.Not only has patient care gained more clarity, but so too has self-care on the part of first responders, according to Smith.“It was hard,” she said. “I think the biggest part that got to all of us is these people don’t have family to be with. That first surge, it all hit us pretty hard because of the sadness that happened down here. We just kind of lean on each other to get through it.”How far this current wave will go is unknown, but by drawing from the past, these first responders say they will be ready to deal with it no matter what is thrown their way.“We just have a better sense of the trajectory, and that is hugely valuable as we go into this next surge,” said Dr. Limes. 2962
