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
Investigators on Monday rolled out an interactive website to help in the search for a missing Iowa college student who disappeared nearly four weeks ago.Mollie Tibbetts,?20, was last seen jogging on the evening of July 18 in the small community of Brooklyn, Iowa, an hour east of Des Moines, according to the Poweshiek County Sheriff's Office. Her family said they reported the University of Iowa student missing the next day after she didn't show up for work at a day care. 487
Investigators have found evidence that a missing University of Iowa student was doing homework on her laptop the night she went missing, according to the woman's brother.Mollie Tibbets, 20, went missing on July 18 when she went jogging near Brooklyn, Iowa. TIbbets' brother, Jake, says investigators found that evidence that she was on her laptop that evening.The older brother of 20-year-old Mollie Tibbetts says investigators told him evidence shows she was doing homework on her computer last Wednesday evening. Tibbets was reportedly dog-sitting for her boyfriend, Jack Dalton, at the time of her disappearance. It is unclear if she returned after her jog, but the new details, family members say it is possible she did. Investigators previously executed a search warrant for Tibbits' Fitbit and social media accounts. A spokesperson for the Iowa Department of Criminal Investigations said Tibbets' case may be the first time Fitbit data has been used in an investigation in the state. 1043
It has been a political dream for Democrats for years: Turning Texas, and its 38 Electoral College votes, blue. Could 2020 be the year that such a progressive dream becomes a reality?THE POLLSPolls suggest a close race. Real Clear Politics, which averages recent polls, puts President Donald Trump up by just 0.2% in Texas. A CBS News poll from early July found presumptive Democratic Nominee Joe Biden trailing by just 1 point in the state. Trump won Texas by more than 800,000 votes in 2016. RECENT MOVESOn Monday, Biden announced the hiring of six staffers in the state, including senior advisers, a state director and a communications director. Not every state has a team in place, so the move suggests Team Biden believes it can force Trump to campaign more in Texas. Biden has also launched digital ads in recent days commemorating the Walmart shooting in El Paso one year ago. Trump, for his part, visited Texas last week and tweeted about Texas several times. 979
