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
In the month since news broke of allegations of sexual harassment and assault against Harvey Weinstein, about 1 in 5 Americans said close friends or family members shared stories about sexual harassment or assault on social media, according to a CNN poll.Headlines about the scandal and the culture in which it flourished were just as ubiquitous, especially as other powerful men were called out. About 66% of people said they've heard a lot of news stories about sexual harassment and assault lately, according to the same poll.But what do people really think of all this coverage and the impact it will have? The CNN poll conducted by SSRS found that most people are hopeful that the surge of attention on sexual harassment and assault could help make things better. 776
Is it safe to drink from a fountain during the coronavirus pandemic?There’s no evidence you can get COVID-19 from the water itself.However, since the virus may linger on surfaces, experts say to avoid fountains if you can or to limit any direct contact when using them.If you don't have a tissue or gloves handy and need to touch the fountain, experts recommend washing your hands afterward.Health officials say schools and businesses should encourage everyone to bring their own water from home, but that fountains should still be cleaned and sanitized for those who need to use them. 593
It appears another week on Capitol Hill will come to a close without any sort of agreement on another stimulus plan. The US Senate adjourned on Thursday for the weekend, and won't resume until Monday.While Congressional Democrats, Senate Republicans and the White House are largely in agreement on the need for a stimulus, agreeing to a framework remains in question. The two sides are at odds over how much of unemployment should be supplemented by the federal government. There is also a debate on offering businesses liability protection from coronavirus-related lawsuits.On Thursday, House Speaker Nancy Pelosi said Democrats won’t back down from their request to have a 0 weekly unemployment supplement.“We're not having a short-term extension... We have said that we're going to have the 0,” Pelosi said.But what about criticism from Republicans that a 0 a week supplement to unemployment is more lucrative than working?“There are all kinds of reasons that weigh in on this pandemic,” Pelosi said. “People have to stay home if their children are not able to go to school or if they don't have childcare. There are a number of reasons. But none of them is 'I want to stay home because I make more money this way than other', maybe some of these employers could pay their workers more."Meanwhile at the White House, President Donald Trump said he is ready to take action on a few items via executive order if need be. With a federal student loan freeze set to lift in eight weeks, and eviction protection ending last week, Trump tweeted, “I’ve notified my staff to continue working on an Executive Order with respect to Payroll Tax Cut, Eviction Protections, Unemployment Extensions, and Student Loan Repayment Options” 1740
Interior Department Secretary Ryan Zinke signed an order Friday morning aiming to expand access for hunters and fishers to public lands and monuments.In what is being described as an "expansive" secretarial order, Zinke's rule would ultimately allow broader access across the board to hunters and fishers on public lands managed by the Interior Department, according to the order.A section of the order also amends the national monument management plan to include or expand hunting and fishing opportunities to the "extent practicable under the law."The order cites a 2007 executive order from President George W. Bush to "facilitate the expansion and enhancement of hunting opportunities and the management of game species and their habitat." It directs agencies to to create a report and plan to streamline how best to enhance and expand access to hunting and fishing on public lands.The Interior Department oversees national parks, wildlife refuges and other federal lands.The secretarial order also aims to expand educational outreach for hunting and fishing to "under served" communities such as minorities and veterans as well as increase volunteer access to federal lands."Today's secretarial order is the latest example of how the Trump administration is actively moving to support hunting and other forms of outdoor recreation on public lands," Zinke said in a statement."Hunting and fishing is a cornerstone of the American tradition and hunters and fishers of America are the backbone of land and wildlife conservation," he said.Interior said Obama administration policies were too restrictive."Through management plans made under the previous administration, which did not appreciate access to hunting and target shooting like this administration does, access and usage has been restricted," said Interior spokeswoman Heather Swift.Zinke's rule will not have to go through a formal rule-making process.It is the second major action from Interior in the last few weeks.In August, Zinke recommended shrinking the boundaries of a handful of national monuments, but stopped short of suggesting the elimination of any federal designations following a review ordered by President Donald Trump.At Trump's direction, Zinke earlier this year launched a review of 27 national monuments, a controversial move that could undo protections for millions of acres of federal lands, as well as limits on oil and gas or other energy production. Interior and the White House have so far resisted releasing the contents of Zinke's full recommendations. 2552
