For 52 years, Tom Hollett has been scanning the water as a lifeguard. But being a lifeguard in Vancouver, Canada means he also keeps watch over frozen water. “I'd rather make 10,000 rescues in the warm ocean than one here,” Hollett says of the frozen lake.This part of Canada, nestled between the Pacific Ocean and the North Shore Mountains, it’s the only part of the country where the average temperature stays above freezing, even in the winter. So, when the lakes start to freeze over, it’s a novelty. The lake attracts visitors, who are often tempted to tread on the thin ice, often times with their pets. “There’s people that don't understand the ice, so they just figure they can walk on it,” Hollett says. When temperatures are colder, as they have been this week, the City of Vancouver Parks and Recreation department dubs a few of their summer lifeguards, "iceguards." "Lifeguards are always scanning and keeping an eye out, so that's what our iceguards do,” Sean Healy with the Vancouver Board of Parks and Recreation says. “When they come out to iceguard, they actually do a walking patrol around the lake. They also keep binocs close at hand.”Hollett says he’s had to make ice rescues before for people’s pets. “Believe it or not, I’ve saved many dogs,” he recalls. “I grabbed their collar like this, reach out and bring ‘em up in the ice." 1369

TAMPA, Fla. — The Tampa Bay area is known for its crystal clear beaches and white sand.Many people see the saltwater as a place to relax and kick back, but Dr. Serene Al-Momen sees it as a vast area of opportunity to stop the spread of the coronavirus.Specifically with what lies under the surface."The jellyfish is the component of the sensor that basically makes the cell emit light when a pathogen from the air is connected to it or binds to it," Dr. Al-Momen said.Dr. Al-Momen is the CEO of the company Senseware. She said the jellyfish is helping her team identify the coronavirus in the air.Her team works to find what's in the air behind the scenes. They do it with a sensor box not much bigger than an Amazon Echo at home.The sensor can detect pathogens in the air like Ecoli, SARS and anthrax.In March, they shifted gears in what type of pathogen they wanted to find."We took what we had and we kind of improved on it to really meet the challenges of today with COVID," Dr. Al-Momen said.The sensor can count particles down to the smallest micron that the common eye would never catch.To detect the coronavirus, they made adjustments."For COVID, we have the SARS code 2 antibody in that cell. So, what happens is when we get the sample of the air and the sensor gets the sample of the air there is a pathogen that binds into the cell and connects to it it will emit light," Dr. Al-Momen said.To help identify pathogens scientists use a luminescent component from a jellyfish; something that is nothing new when working to identify viruses and diseases."This particular methodology was created in the early 2000s by the MIT Lincoln Labs to specifically identify anthrax threats when anthrax was an issue," Dr. Al-Momen said.The jellyfish's protein helps light up a cell when a pathogen from the air is connected to or binds to it.The team then uses sophisticated algorithms that measure the intensity of the light that can determine whether it's positive or negative.The sensors cost tens of thousands of dollars and are geared towards larger corporations such as hospitals and senior care facilities.Senseware is currently in the Beta testing phase and they hope to offer the machine commercially by November.For more information about Senseware, visit their website.

MONTPELIER, Vt. – Among the maple trees in west Vermont, on the outskirts of Montpelier, sits Morse Farm and Sugar Works. Elliott Morse and his brother Burr Morse run the farm. Their families have been farmers in the region for seven generations. “We were dairy farmers for most of those generations,” said Burr. “My father didn’t like dairy farming, that just wasn’t what you wanted to do.” Under Harry Morse senior, Burr’s father, the farm focused on tapping maple. When it was Burr’s turn to run things, he thought the land was suited to do something else too. The farm had enough land and the right topography for cross country skiing. “This was a junction here and really the main entrance to the ski system,” Burr explained as he walked the farm’s ski trails. “Skiing livened the place up in the winter.” Cross-country skiing on Morse Farm became a popular local attraction in Montpelier for more than two decades. “Families had fun and year after year they’d come up to ski,” Burr added. However, Morse Farm had to close its ski trails last year as the weather has become more unpredictable, and the snowfall amounts have been inconsistent. Over the past decade, Vermont has had almost 200 inches of snow one year, and barely 50 inches the next. “It’s not easy, it’s not easy at all. Skiing was with us for 20 years and now it’s like it died,” said Burr. The change has been tough for Burr Morse to accept, but necessary. Now he can focus all his attention to maple sugaring in hopes of minimizing the unpredictable weather’s effect on that business. “There are a lot of sugar maker walking around like, there’s not a problem. Nothing’s wrong, nothing’s wrong. I don’t have the patience for that,” he said. “I am a realist. I have my eyes open on the farm and darn it all I am concerned.” He’s concerned over how long technology, like vacuum pumps hooked onto maple trees, will work to draw sap from the trees when the weather is unseasonable. But he’s also concerned over how many more generations of the Morse family will be able to enjoy running the family farm. “I have just one grandchild 6-year-old girl and we love her to pieces and if she wants to carry on this place someday that would be great,” Burr said. “But will the place be here for her if she makes that choice I don't know and that's what I worry about.” 2347

Colorado Gov. Jared Polis signed an executive order on Thursday that granted pardons to people who have been convicted of possessing one ounce or less of marijuana. “We are finally cleaning up some of the inequities of the past by pardoning 2,732 convictions for Coloradans who simply had an ounce of marijuana or less," Polis said. "It’s ridiculous how being written up for smoking a joint in the 1970s has followed some Coloradans throughout their lives and gotten in the way of their success."This pardon applies to all state-level convictions of possession for one ounce or less of marijuana. Read the full executive order here. Polis said too many Coloradans have "been followed their entire lives by a conviction for something that is no longer a crime, and these convictions have impacted their job status, housing, and countless other areas of their lives."In June, Polis signed the bipartisan HB 20-1424 Social Equity Licensees In Regulated Marijuana, which was sponsored by Rep. James Coleman, Sen. Julie Gonzales and Sen. Vicki Marble, including an amendment sponsored by Sen. Gonzales. This authorizes the governor to grant pardons to people who were convicted of possessing up to two ounces of marijuana. Individuals who fall in this category don't need to apply for the pardon. Those who were convicted of municipal marijuana crimes, or individuals arrested or issued a summons without a conviction, aren't included in the pardons. This new law went into effect in October.
