2nd earthquake in as many days off Vancouver Island
A 4.8-magnitude earthquake shook homes on Vancouver Island Friday night, but no damage has been reported, according to Earthquakes Canada. (Earthquakes Canada) CTV News Vancouver Island Staff Follow | Contact Published Nov. 26, 2022 2:38 p.m. MST
A 4.8-magnitude earthquake shook homes on Vancouver Island Friday night, but no damage has been reported, according to Earthquakes Canada.
The federal agency says the quake happened at 7:50 p.m., 34 kilometres west-northwest of Tofino, at a depth of 32 kilometres below the Pacific Ocean.
Former Tofino mayor and current MLA Josie Osborne reported on Twitter that her "whole house shuddered," and urged residents to check their earthquake preparedness.
Others on social media reported feeling the quake in the Comox Valley, and Earthquakes Canada shows reports that the quake was felt as far away as Powell River and the Lower Mainland.
Friday's quake was the second off the west coast of Vancouver Island in as many days.
Around 5:10 a.m. Thursday, a smaller earthquake was detected considerably farther from shore, but was nonetheless lightly felt by some Island residents.
That quake occurred 288 kilometres southwest of Tofino, at a depth of one kilometre. It had a magnitude of 4.0.
Sask. farmers, researchers worry investor-bought land 'empties out the countryside'

About 2% of land controlled by ‘non-farmers,' and that
As Terry Boehm sits on a tractor-powered snowblower on a cold winter day and clears a path to his shop, the grain and seed producer thinks about a more important path: the one his town and its young farmers will travel moving forward.
Boehm comes from a long line of farmers near Colonsay, Sask., starting from when his great grandfather arrived more than 100 years ago to the area, about 50 kilometres southeast of Saskatoon.
Saskatchewan, a resource-rich province, makes up about 40 per cent of Canada's farmland. Family farms like Boehm's own the vast majority of it, but researchers say large agriculture companies or investors who rent out farmland now control about two per cent.
Boehm, who has long advocated for farmers' rights, and researchers say this trend could speed up rising costs and force smaller, local farmers to expand or get out of the industry altogether, which could ultimately lead to fewer people in small rural communities.
"This is creating a situation where farmers are really the cash cow to be milked on every teat," Boehm told CBC News.
"The amount of land that they own across the board is not huge in terms of percentage, but in certain cases they may own tens of thousands of acres or even more sometimes," he said.
Most communities are withering. There simply aren't enough people.- Farmer Terry Boehm
Magnan said buying farmland is used as a strategy to diversify a person or company's portfolio and to hedge risks such as inflation.
While it's a good investment, it's a blow to small towns, Magnan said.
"What we're finding is that ownership is in fewer and fewer hands and that has a really tangible effect on local communities. It empties out the countryside," he said.
He and Boehm worry that if fewer people are involved in agriculture, it will be more difficult to sustain services such as schools and hospitals in small towns.
"Most communities are withering. There simply aren't enough people," Boehm said.
"Just being able to have enough people to be engaged in the day-to-day requirements of operating in a small community, it falls on less and less shoulders."
Katherine Aske, a field co-ordinator at the University of British Columbia (UBC) Farm, was recently part of a research team based at the University of Manitoba looking into how farmland tenure is changing on the Prairies.
She said the market value of farmland in Alberta is now completely disconnected from how much farmers can make on the land through producing.
"This is a massive problem," Aske said.
"As farmland prices rise, this becomes more of a pervasive problem because fewer and fewer actors or people are able to purchase land at all."
Land ownership rules
Saskatchewan's land ownership rules changed almost two decades ago. Until 2003, people had to live in Saskatchewan to own land in the province. Now, ownership is open to Canadians or Canadian companies that are not publicly traded.
"It's really since those rules were changed … that you've seen investor groups and other wealthy individuals acquire quite a bit of land," Magnan said.
"With a lot of inflation I expect to see a lot more interest in purchasing farmland by non-farmers."
Saskatchewan still has some of the strictest land ownership rules in Canada. However, the province does grant exemptions — many on the condition that owners rent out to locals.
Annette Desmarais, Canada Research Chair in human rights, social justice and food sovereignty at the University of Manitoba, said renting land can have its problems, including landlords not taking care of the land enough or creating strict rules.
"What if you wanted to start farming organically and you were renting land from an investor who's not interested in organic farming? Your autonomy to make decisions about how you want to farm are going to be affected," Desmarais said.
One of the largest investors in Saskatchewan land is Robert Andjelic, who rents out more than 225,000 acres.
He said tenants bid on his land and therefore control the prices.
"If you get 10 bidders, they're the ones that dictate the price," he said.
Andjelic said renting offers farmers a chance to start or grow their careers without the risks of ownership — as long as they take care of the land.
"Land is our bread and butter. We have to take care of it the best we can, return the nutrients and everything else back to it, and not just mine it. We farm it, not mine it. If they mine it, they're not going to be my tenant," he said.
Policy changes
Canadian farmers and academics, including Desmarais, are fighting for protections against agricultural monopolies amid concern that investors will make up an even larger chunk of the land ownership base.
"Assuming that most people would want to see many more farms, many more opportunities for young farmers to be able to access, then you develop policy to make sure that that happens," Desmarais said.
Some researchers say provinces should hike taxes to discourage vast land ownership. Others want caps on how much land one operation can own.
But the province's agriculture minister says the Saskatchewan Party won't go down that road.
"If someone wants to come along and offer me X-amount of dollars for my property, that should be my choice to have the right to sell it," David Marit said in a recent interview with CBC News.
"But if the government puts a policy in that says 'no, you can't sell it to him because he's hit his cap,' and you have to sell it to someone else, you know what you've done? You've controlled the whole sale of land."
When asked if he's concerned about the harm to small towns and disappearing farmers, Marit said "we're just seeing evolution in time."
"The community I came from 15 years ago lost a school too, as well, just because of people moving on, you were seeing this intergenerational change in farming," he said.
"That just seems to be what's happening."
As for farmer Terry Boehm, he said he does want to sell or rent his land when he gets older. He is adamant on keeping his town alive.
"You can't control everything. My preference would be to sell to a local farmer that's still living in the area or to a younger person that wants to start up in agriculture," he said.
TD Bank pauses Canada Post loan program weeks after national expansion
A spokeswoman for TD Bank confirmed that the MyMoney Loan program has been placed on pause indefinitely because of unspecified issues with processing.
“Since the launch, the product was paused both online and in physical locations, after experiencing processing issues,” Amy Thompson said in an email to BNNBloomberg.ca. “We're still working through this and will update accordingly.”
Canada Post referred questions about the status of the program to TD Bank.
The loan program offered variable or fixed loans ranging from $1,000 to $30,000. Repayments could be spread over one- to seven-year terms.
People did not need collateral security for the unsecured-term loans that were based on credit scores. Eligibility requirements included that people had an annual income of $1,000 or more, had not declared bankruptcy and were Canadian citizens or permanent residents.
Earlier this fall, the Crown corporation and TD announced a national expansion for the program that was first launched in 2021 at locations in Nova Scotia, Manitoba and Ontario.
An October Canada Post news release promoted the program as aimed at expanding financial services access to more Canadians by “combining the reach and trust of Canada Post’s national post office network with personal loans for amounts as low as $1,000 and competitive interest rates.”
The national launch was intended to make the program available in rural, remote and Indigenous communities, the release said, noting that the initial market test “demonstrated the potential of the MyMoney Loan to help meet the needs of many Canadians, including those who are new to credit.”
Little is known about how social behavior develops in the earliest stages of life. But most animals––including humans––are born with an innate ability to interact socially or form bonds with others. And that contributes to success throughout life.
Now, a new animal study points to a gene that is important for the earliest development of basic social behaviors.
The work also suggests that exposure to certain drugs and environmental risk factors during embryonic development can cause changes to this gene, leading to alterations in social behavior that are similar to those found in individuals who have autism. Much to their surprise, the researchers also found they could reverse some of the effects using an experimental drug.
“This study helps us understand at the molecular level why sociability is disrupted during the very earliest stages of life,” says Randall T. Peterson, Ph.D., the corresponding author of the study and dean of the University of Utah College of Pharmacy. “It also gives us an opportunity to explore potential treatments that could restore sociability in these animals and, perhaps in time, eventually in humans as well.”
More broadly, their findings suggest that the gene—TOP2a—controls a large network of genes that are known to increase the risk of autism. It also may serve as a link between genetic and environmental factors that contribute to onset of disorder, Peterson adds.
The study, conducted by University of Utah Health researchers and colleagues nationwide, appears in the Nov. 23 issue of Science Advances.
Anti-social animals
Scientists suspect many social traits are determined before birth. But the precise mechanisms involved in this process remain murky. One promising area of research suggests that social behavior and other characteristics and traits are influenced not only by our genetic makeup but also how and where we live.
To test this model, the scientists evaluated whether environmental exposures during embryonic development could influence social behavior. Peterson and his colleagues exposed zebrafish embryos to more than 1,100 known drugs––one drug per 20 embryos––for 72 hours beginning three days after conception.
The researchers determined that four of the 1,120 tested drugs significantly reduced sociability among the zebrafish. Fish exposed to these drugs were less likely to interact with other fish. It turned out that the four medications all belonged to the same class of antibiotics, called fluoroquinolones. These drugs are used to treat upper and lower respiratory tract infections in people.
When the scientists gave a related drug to pregnant mice, the offspring behaved differently when they became adults. Even though they appeared normal, they communicated less with other mice and engaged in more repetitive acts—like repeatedly poking their head in the same hole—than other rodents.
A basis for sociability
Digging deeper, the researchers found that the drugs suppressed a gene called TOP2a, which, in turn, acted on a cluster of genes that are known to be involved in autism in humans.
They also found that the cluster of autism-associated genes shared another thing in common—a higher than usual tendency to bind a group of proteins called the PRC2. The researchers hypothesized that Top2a and the PRC2 work together to control the production of many autism-associated genes.
To determine whether the anti-social behaviors could be reversed, the research team gave embryonic and young zebrafish an experimental drug called UNC1999, which is known to inhibit the PRC2. After treatment with the drug, fish exposed to fluoroquinolones were more likely to swim closer to other fish, demonstrating that the drug helped restore sociability. They saw similar results with other drugs known to inhibit the same key gene, TOP2a.
“That really surprised me because I would've thought disrupting brain development when you're an embryo would be irreversible,” Peterson says. “If you don’t develop sociality as an embryo, you’ve missed the window. But this study suggests that even in those individuals later in life, you can still come in and inhibit this pathway and restore sociality.”
Moving forward, the researchers plan to explore how and why this drug had this effect.
Although the scientists only found four compounds that are Top2a inhibitors, evidence suggests hundreds of other drugs and naturally occurring compounds in our environment can inhibit its activity.
“It’s possible that these four compounds are just the tip of the iceberg in terms of substances that could be problematic for embryonic exposure,” Peterson says.
However, Peterson notes that this study was conducted in animals, and more research needs to be done before any of its results can be confirmed in humans. Therefore, he cautions against drawing conclusions about real-world applications.
“We have no evidence that fluroquinolones or any other antibiotic causes autism in humans,” Peterson says. “So, there is no reason to stop using antibiotics. What this paper does identify is a new molecular pathway that appears to control social development and is worthy of further exploration.”

Most people with long Covid face stigma and discrimination
The majority of people living with Long Covid experience some form of stigma directly related to their condition, according to a new study published in the journal PLOS ONE.
An estimated 2.3 million people are living with Long Covid in the UK according to the Office for National Statistics data, and numbers are not decreasing due to limited treatment options and continued high Covid infection rates. Testimonies illustrate profound stigmas experienced by people living with Long Covid, but until now there has been no quantitative assessment of the burden.
In the study, conducted by researchers at the University of Southampton and Brighton and Sussex Medical School and co-designed by people living with Long Covid (from the charity Long Covid Support), people who took part in the 2020 Long Covid online survey were invited to complete a follow up survey in November 2021.
More than 1100 people took part, including 966 people from the UK, and were asked about their experiences of stigma in three areas: Enacted stigma where individuals were directly treated unfairly due to their health condition; internalised stigma where people felt embarrassed or ashamed of their health condition, and anticipated stigma, which is the individual’s expectation they will be treated poorly because of their condition.
Ninety-five percent of people experienced at least one type of stigma at least ‘sometimes’, and 76% experiencing it ‘often’ or ‘always’, according to the results.
Dr Marija Pantelic, Lecturer in Public Health at Brighton and Sussex Medical School, who led the development of the stigma questions in the follow up survey, said: “There have been countless anecdotal reports of the stigma, dismissal and discrimination faced by people living with Long Covid. This study was the first to empirically measure this stigma and estimate prevalence. We were shocked to see just how prevalent it is, but the findings also empower us to do something about it. With the stigma questionnaire we developed, we can measure changes over time and the effectiveness of urgently needed anti-stigma interventions.”
In the study, nearly two thirds (63%) of people reported experiences of stigma such as being treated with less respect or people they care about stopping contact with them due to their health condition, while 91% expected to experience stigma and discrimination, for example they thought many people did not consider Long Covid to be a real illness or they anticipated judgment. Eighty-six percent of respondents felt a profound sense of shame related to having Long Covid - they were embarrassed of their illness and felt ‘very different’ from people without Long Covid.
In the study, 61% of people said they were very careful who they tell about their condition, and about one third (34%) of respondents regretted having told people about it. Overall, the prevalence of experiencing stigma was higher in those who reported having a clinical diagnosis of Long Covid compared to those without or who were unsure (83% v 69%).
Nisreen Alwan, Professor of Public Health at the University of Southampton and co-lead author of the study, added: “We were surprised to find that people with a clinical diagnosis of Long Covid were more likely to report stigma than people without a formal diagnosis. We are not sure why this is - perhaps because they are more likely to share their health status with others or perhaps because they have engaged more with health services. More research is needed to unpack the potential mechanisms of how and where this stigma is manifested, and who is most likely to stigmatise and be stigmatised.”
Claire Hastie from the charity Long Covid Support who also worked on the study, said: “Sadly we see the results of stigma all too often among members of our support group. In addition to the significant health burden of Long Covid, the stigma and discrimination associated with the condition can lead to relationship breakdowns and problems at work. These cause immense additional distress, which itself can compromise healing. It is vital that people with the condition are believed and supported to help their chances of recovery.”
“The stigma attached to Long Covid is harming people living with Long Covid and is likely to leave a devastating mark on our society and health service provision,’ Dr Pantelic added. “We know from decades of research with other long-term conditions such as asthma, depression, and HIV that stigma has dire consequences for public health. Fear of stigma is also likely to drive people away from health services and other support, which over time has detrimental consequences on people’s physical and mental health.”

A new study of 68 city centres in Great Britain – comparing ‘greenness’ of tree cover, vegetation and the presence of parks – has linked lower scores with higher levels of poor health, economic, education, crime and other deprivation outcomes.
The PLOS One study led by Flinders University, University of Sheffield, University of Melbourne and Environmental Protection Authority Victoria researchers, evaluated urban centres with larger populations of more than 100,000 people to create a metric of urban ecosystems and vegetation and human health, social equity and biodiversity.
Five cities in southern England were ranked highest (Exeter, Islington, Bristol, Bournemouth and Cambridge) and five in the previously industrial north had the lowest from Leeds, Liverpool, Sheffield, Middlesbrough to Glasgow at the bottom.
“While previous studies have measured greenness in broader suburban areas, our study focuses on city centres where people of diverse backgrounds spend much time at work, recreation and shopping,” says author Dr Jake Robinson, a European microbial ecologist and adjunct Flinders University researcher.
“While people’s lives are enhanced by the greenness of their city, many cities have high tree densities in the suburban areas but not their urban centres.
“Not surprisingly, the urban centres with higher tree and vegetation cover, public green spaces including parks and sports fields, have developed after more focus on urban planning rather than urban sprawl and industrial growth, and now have lower levels of deprivation in general, including in human health metrics.”
In addition, the urban centres with larger populations had lower tree coverage and lower normalised difference vegetation index, measured by satellite observations of light absorption and reflection.
These disparities in city centre greenness across Britain should be incorporated in further city planning, says co-author Dr Paul Brindley from the University of Sheffield
“This work could help inform efforts by local authorities and urban planners to monitor greening interventions and boost the greenness of city centres in a more equitable manner,” Dr Brindley says.
It is projected that nearly 70% of the world’s population will be living in towns and cities by 2050. Global urbanisation is putting increasing pressure on biodiversity and human health, including with harmful air pollution and other gases and particulate matter, and degrading habitats.
“The need to re-imagine and re-develop our urban city centres due to digital shopping technologies and societal changes provides and important opportunity to explicitly consider the enhancement of urban centre biodiversity,” the research concludes.
The research article, ‘Urban centre green metrics in Great Britain: A geospatial and socioecological study’ (2022), by JM Robinson, S Mavoa, K Robinson and P Brindley has been published in PLoS ONE DOI: 10.1371/journal.pone.0276962

A new study finds that Great Britain’s city centers vary considerably in their green attributes—such as tree cover, vegetation, and presence of parks—with potential implications for human health, social equity, and biodiversity. Dr. Jake Robinson of Flinders University and colleagues at the University of Sheffield, U.K., present these findings in the open-access journal PLOS ONE on November 23, 2022.
Trees, vegetation cover, and public greenspaces, including parks and sports fields, contribute to biodiversity and human health in urban ecosystems. While numerous prior studies have measured such “greenness” in broader suburban areas, none have focused specifically on city centers, where people of diverse backgrounds spend much time on activities such as work, recreation, and shopping.
Because many people’s lives may be affected by the greenness of city centers, Robinson and colleagues analyzed green metrics of urban centers for all 68 municipalities in Great Britain with populations of at least 100,000. Their analysis incorporated three metrics of greenness: tree cover, presence of greenspaces, and the normalized difference vegetation index (NDVI), which uses satellite observations of light reflection and absorption to measure vegetation cover in a given area.
Combining all three metrics into a single greenness score, the researchers found that Exeter’s urban center ranks highest, followed by Islington, Bristol, Bournemouth, and Cambridge. Glasgow’s urban center is least green, with Middlesbrough, Sheffield, Liverpool, and Leeds also in the lowest five. The authors note that the top five urban centers are all located in the south of England, while the bottom five urban centers relate to ex-industrial areas in the north of Great Britain.
Further analysis uncovered a statistical link between a lower greenness score and higher levels of deprivation, as measured according to crime risk, health, economics, education, and other related metrics. In addition, areas with larger populations had lower tree coverage and lower NDVI scores, but did not have fewer greenspaces.
These findings highlight disparities in greenness of city centers across Great Britain. Future research could incorporate alternative metrics of greenness or apply a similar analysis to city centers outside of Great Britain.
Dr. Robinson adds: “This work could help inform efforts by local authorities and urban planners to boost the greenness of city centers in an equitable manner.”
