In cities across America, volunteers stand armed and ready to fight a different kind of virus infecting the planet."Everything's changed right now. Everything is to-go, so it's turned into a disposable society again," said Miah Earn.Earn lives in Hillcrest, an urban neighborhood in San Diego, California. She's out on the streets cleaning up liter, protecting the city she's called home for over 30 years."It's a mess out here. It really is," said Earn. "I'm seeing masks and gloves everywhere. I don't understand why people can't hit the garbage with them."Ian Monahan is with I Love a Clean San Diego and says they've seen more trash in general during the pandemic. "Increased packaging, whether it's to-go containers, whether it's PPE, whether it's shipping products. Unfortunately, it's ending up on the streets, and we've got to protect it, so it doesn't get into the ocean or waterways at the end of the day," said Monahan. During a global clean-up event this month, Monahan says for the first time they'll be tracking the amount of PPE collected. "It's actually a whole new anomaly in our clean-ups. We really didn't see them before. And mostly it's the disposable masks, which people think are paper, they're actually plastic," said Monahan. Eventually, they will break down into microscopic pieces that will outlive us hundreds of years, and they can threaten wildlife and food supplies.Around the world, it's estimated nearly 200 billion disposable face coverings and gloves are being used each month because of the pandemic.The environmental conservation organization OceansAsia is documenting this new pandemic of pollution, capturing video of disposable face masks washing up on one of Hong Kong's most remote islands."Once you see this, you can't really unsee it," said Mitch Silverstein, chapter manager for Surfrider Foundation San Diego County.The nonprofit is piloting a program to make clean-ups more convenient, loaning the tools to businesses for the public to borrow. Volunteers have the option to fill out a data sheet with what they collected, which now includes PPE. Data collected around the world could help inform policy for products doing the most damage."Use reusable items, a reusable mask, reusable gloves when you're cleaning up," said Monahan. They say it will take a global shift in thinking to heal mother earth from what some call this human-made sickness. 2402

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 seems people are not letting the coronavirus pandemic damper their holiday spirit as more than 3 million travelers took to the skies the weekend before Christmas.According to The Transportation Security Administration daily tally tracker, 1,064,619 people flew on Sunday, 1,073,563 traveled on Saturday, and 1,066,747 were screened on Friday.This marks the first time since March 16 that checkpoint numbers were over 1 million on consecutive days.Despite an increase in travelers, the amount of Americans traveling before Christmas was nowhere near the amount that traveled the weekend before Christmas last year - that weekend, TSA screen 7.6 million Americans.The surge in travelers comes despite the Centers for Disease Control and Prevention advising Americans to stay home and not travel during the holiday to slow the coronavirus spread. 854

It was supposed to be a make-or-break moment.When the Trump administration said last September it was pulling the plug on Deferred Action for Childhood Arrivals, March 5 was the program's official end date.But it was so much more than a date on the calendar. It was the looming deadline that finally was going to force Congress to tackle the perennial political hot potato of immigration.Protesters organized around it. Lawmakers invoked it in fiery speeches. The President warned that time was running out to make a deal.Now, here we are, just days from that fateful date and no solution in sight. And what about Monday's deadline? Well, it still exists on paper. But it's become more of a symbolic marker than a moment when anything major is expected to happen for the roughly 700,000 DACA recipients.Here's a look at how we got here, and what happens next: How did this happen? 893
