U of G study shows there's little chance of catching COVID from grocery store surfaces – GuelphToday

Wearing gloves while shopping and wiping down food packaging at home may be unnecessary, as new University of Guelph research suggests the chances of getting infected with COVID-19 from grocery store surfaces are very low.

A team of U of G scientists, who swabbed hundreds of high-contact surfaces in grocery stores, found that none tested positive for SARS-CoV-2, the virus that causes COVID-19.

No surface location harboured SARS-CoV-2, from a payment station and a deli counter to the refrigerated food section or the carts and baskets.

The team led by Department of Food Science professor Maria Corradini and PhD student Maleeka Singh concluded that as long as recommended cleaning protocols are followed in stores, the risk of exposure from a contaminated surface at a grocery store is low.

“We believe that cleaning and disinfecting contact surfaces along with wearing masks significantly minimize the risk of transmission from surfaces in grocery stores to humans,” said Corradini, holder of the Arrell Chair in Food Quality.

The study was recently published in the journal Current Research in Food Science and featured on The Conversation Canada. Co-authors included Lawrence Goodridge, professor in the Department of Food Science, and Drs. Robert Hanner and Steven Newmaster, professors in the Department of Integrative Biology.

The team began their study last year shortly after the release of research that suggested SARS-CoV-2 could survive for hours or even days on surfaces in environments such as hospital wards and patients’ rooms.

To determine whether similar results would be found on surfaces in grocery stores, the team took 957 samples at four Ontario food retailers over a month during the second wave of the virus.

They swabbed the handles of grocery carts and baskets, payment terminals and conveyor belts at checkouts, surfaces around deli counters, and the plastic and metal handles in frozen food sections, as other studies had shown these areas were most likely to harbour viruses and bacteria.

No matter whether the store was in an urban or suburban area, the sampling day or time, or the location of the surface within the store or the surface material, none of the samples tested positive for the virus.

“These results suggest that if stores enforce regular sanitizing routines and monitor the health of store personnel, the risk of exposure from high-touch surfaces within a grocery store is low,” said Corradini.

The authors note their findings support those of the U.S. Centers of Disease Control and Prevention, which also concluded that while transmission of COVID-19 through surfaces is feasible, it is very unlikely as the main transmission route is through droplet or airborne transmission from infected people.

Russian crew returns from shooting the first feature film on the ISS – Yahoo Movies Canada

Published

 on


Shooting for the first feature-length movie in space has wrapped. Space.com reports Russian actress Yulia Pereslid, producer Klim Shipenko and cosmonaut Oleg Novitskiy have returned to Earth after the first two spent 12 days filming their movie The Challenge aboard the International Space Station. The three left the ISS in a Soyuz spacecraft at 9:14PM Eastern on October 16th and landed in Kazakhstan just a few hours later, at 12:35AM.

Pereslid and Shipenko arrived on October 5th through an agreement between the Russian space agency Roscosmos, the TV network Channel One and the production studio Yellow, Black and White. Novitskiy had been there since April 9th as part of his regular duties, although he also played a key role — the movie has Pereslid play a surgeon who makes an emergency visit to the ISS to operate on the cosmonaut.

The filming required significant sacrifices for some of the ISS crew. NASA astronaut Mark Vande Hei and Russian cosmonaut Pyotr Dubrov were originally slated to return aboard the Soyuz capsule, but both have had their stays extended by six months to accommodate the film producers. Vande Hei will set a record for the longest spaceflight by a US astronaut as a result, spending exactly one year in orbit. Pereslid also broke ground as the first professional actor to visit space, beating William Shatner by roughly a week.

It will be a while before The Challenge is ready to watch, and it’s safe to say the production is aimed primarily at a Russian audience. It’s a major milestone for private uses of space, though, and hints at a future when Tom Cruise and other stars are frequently blasting off to produce shows in orbit.

Russian actor, director arrive back on earth from ISS – Euronews

Published

 on


A Soyuz space capsule carrying a cosmonaut and two Russian filmmakers has returned to Earth after leaving the International Space Station (ISS) earlier on Sunday.

The capsule landed on the steppes of Kazakhstan carrying Russian actor Yulia Peresild and film director Klim Shipenko, who returned to Earth after filming scenes for the world’s first movie in orbit – a project the Kremlin said would help burnish the nation’s space glory.

Peresild and Shipenko rocketed into orbit in a Russian Soyuz spacecraft on October 5 for a 12-day stint on the station to film segments of the movie titled “Challenge,” in which a surgeon played by Peresild rushes to the space station to save a crew member who needs an urgent operation in orbit.

The pair returned to Earth on Sunday with another Russian cosmonaut, Oleg Novitskiy, who also stars as the ailing cosmonaut in the movie.

VIDEO: NASA’s asteroid hunter Lucy soars into sky with diamonds – Abbotsford News

Published

 on


A NASA spacecraft named Lucy rocketed into the sky with diamonds Saturday morning on a 12-year quest to explore eight asteroids.

Seven of the mysterious space rocks are among swarms of asteroids sharing Jupiter’s orbit, thought to be the pristine leftovers of planetary formation.

An Atlas V rocket blasted off before dawn, sending Lucy on a roundabout journey spanning nearly 4 billion miles (6.3 billion kilometers). Researchers grew emotional describing the successful launch — lead scientist Hal Levison said it was like witnessing the birth of a child. “Go Lucy!” he urged.

Lucy is named after the 3.2 million-year-old skeletal remains of a human ancestor found in Ethiopia nearly a half-century ago. That discovery got its name from the 1967 Beatles song “Lucy in the Sky with Diamonds,” prompting NASA to send the spacecraft soaring with band members’ lyrics and other luminaries’ words of wisdom imprinted on a plaque. The spacecraft also carried a disc made of lab-grown diamonds for one of its science instruments.

In a prerecorded video for NASA, Beatles drummer Ringo Starr paid tribute to his late colleague John Lennon, credited for writing the song that inspired all this.

“I’m so excited — Lucy is going back in the sky with diamonds. Johnny will love that,” Starr said. “Anyway, if you meet anyone up there, Lucy, give them peace and love from me.”

The paleoanthropologist behind the fossil Lucy discovery, Donald Johanson, had goose bumps watching Lucy soar — “I will never look at Jupiter the same … absolutely mind-expanding.” He said he was filled with wonder about this “intersection of our past, our present and our future.”

“That a human ancestor who lived so long ago stimulated a mission which promises to add valuable information about the formation of our solar system is incredibly exciting,” said Johanson, of Arizona State University, who traveled to Cape Canaveral for his first rocket launch.

Lucy’s $981 million mission is the first to aim for Jupiter’s so-called Trojan entourage: thousands — if not millions — of asteroids that share the gas giant’s expansive orbit around the sun. Some of the Trojan asteroids precede Jupiter in its orbit, while others trail it.

Despite their orbits, the Trojans are far from the planet and mostly scattered far from each other. So there’s essentially zero chance of Lucy getting clobbered by one as it swoops past its targets, said Levison of Southwest Research Institute, the mission’s principal scientist.

Lucy will swing past Earth next October and again in 2024 to get enough gravitational oomph to make it all the way out to Jupiter’s orbit. On the way there, the spacecraft will zip past asteroid Donaldjohanson between Mars and Jupiter. The aptly named rock will serve as a 2025 warm-up act for the science instruments.

Drawing power from two huge circular solar wings, Lucy will chase down five asteroids in the leading pack of Trojans in the late 2020s. The spacecraft will then zoom back toward Earth for another gravity assist in 2030. That will send Lucy back out to the trailing Trojan cluster, where it will zip past the final two targets in 2033 for a record-setting eight asteroids visited in a single mission.

It’s a complicated, circuitous path that had NASA’s science mission chief, Thomas Zurbuchen, shaking his head at first. “You’ve got to be kidding. This is possible?” he recalled asking.

Lucy will pass within 600 miles (965 kilometers) of each target; the biggest one is about 70 miles (113 kilometers) across.

“Are there mountains? Valleys? Pits? Mesas? Who knows? I’m sure we’re going to be surprised,” said Johns Hopkins University’s Hal Weaver, who’s in charge of Lucy’s black-and-white camera. “But we can hardly wait to see what … images will reveal about these fossils from the formation of the solar system.”

NASA plans to launch another mission next month to test whether humans might be able to alter an asteroid’s orbit — practice in case Earth ever has a killer rock headed this way.
