Putting your toddler in front of the TV? You might hurt their ability to process the world around them, new data suggests

Peer-Reviewed Publication

DREXEL UNIVERSITY

Babies and toddlers exposed to television or video viewing may be more likely to exhibit atypical sensory behaviors, such as being disengaged and disinterested in activities, seeking more intense stimulation in an environment, or being overwhelmed by sensations like loud sounds or bright lights, according to data from researchers at Drexel’s College of Medicine published today in the journal JAMA Pediatrics.

According to the researchers, children exposed to greater TV viewing by their second birthday were more likely to develop atypical sensory processing behaviors, such as “sensation seeking” and “sensation avoiding,” as well as “low registration” — being less sensitive or slower to respond to stimuli, such as their name being called, by 33 months old.

Sensory processing skills reflect the body’s ability to respond efficiently and appropriately to information and stimuli received by its sensory systems, such as what the toddler hears, sees, touches, and tastes.

The team pulled 2011-2014 data on television or DVD-watching by babies and toddlers at 12- 18- and 24-months from the National Children’s Study of 1,471 children (50% male) nationwide.

Sensory processing outcomes were assessed at 33 months using the Infant/Toddler Sensory Profile (ITSP), a questionnaire completed by parents/caregivers, designed to give insights on how children process what they see, hear and smell, etc.

ITSP subscales examine children’s patterns of low registration, sensation seeking, such as excessively touching or smelling objects; sensory sensitivity, such as being overly upset or irritated by lights and noise; and sensation avoiding — actively trying to control their environment to avoid things like having their teeth brushed. Children score in “typical,” “high” or “low” groups based on how often they display various sensory-related behaviors. Scores were considered “typical” if they were within one standard deviation from the average of the ITSP norm.

Measurements of screen exposure at 12-months were based on caregiver responses to the question: “Does your child watch TV and/or DVDs? (yes/no),” and at 18- and 24- months based on the question: “Over the past 30 days, on average, how many hours per day did your child watch TV and/or DVDs?”

The findings suggest:

• At 12 months, any screen exposure compared to no screen viewing was associated with a 105% greater likelihood of exhibiting “high” sensory behaviors instead of “typical” sensory behaviors related to low registration at 33 months 
• At 18 months, each additional hour of daily screen time was associated with 23% increased odds of exhibiting “high” sensory behaviors related to later sensation avoiding and low registration.
• At 24 months, each additional hour of daily screen time was associated with a 20% increased odds of “high” sensation seeking, sensory sensitivity, and sensation avoiding at 33 months.

The researchers adjusted for age, whether the child was born prematurely, caregiver education, race/ethnicity and other factors, such as how often the child engages in play or walks with the caregiver.

The findings add to a growing list of concerning health and developmental outcomes linked to screen time in infants and toddlers, including language delay, autism spectrum disorder, behavioral issues, sleep struggles, attention problems and problem-solving delays.

“This association could have important implications for attention deficit hyperactivity disorder and autism, as atypical sensory processing is much more prevalent in these populations,” said lead author Karen Heffler, MD, an associate professor of Psychiatry in Drexel’s College of Medicine. “Repetitive behavior, such as that seen in autism spectrum disorder, is highly correlated with atypical sensory processing. Future work may determine whether early life screen time could fuel the sensory brain hyperconnectivity seen in autism spectrum disorders, such as heightened brain responses to sensory stimulation.”

Atypical sensory processing in kids with autism spectrum disorder (ASD) and ADHD manifests in a range of detrimental behaviors. In children with ASD, greater sensation seeking or sensation avoiding, heightened sensory sensitivity and low registration have been associated with irritability, hyperactivity, eating and sleeping struggles, as well as social problems. In kids with ADHD, atypical sensory processing is linked to trouble with executive function, anxiety and lower quality of life.

“Considering this link between high screen time and a growing list of developmental and behavioral problems, it may be beneficial for toddlers exhibiting these symptoms to undergo a period of screen time reduction, along with sensory processing practices delivered by occupational therapists,” said Heffler.

The American Academy of Pediatrics (AAP) discourages screen time for babies under 18-24 months. Live video chat is considered by the AAP to be okay, as there may be benefit from the interaction that takes place. AAP recommends time limitations on digital media use for children 2 to 5 years to typically no more than 1 hour per day.

“Parent training and education are key to minimizing, or hopefully even avoiding, screen time in children younger than two years,” said senior author David Bennett, PhD, a professor of Psychiatry in Drexel’s College of Medicine.”

Despite the evidence, many toddlers view screens more often. As of 2014, children age 2 and under in the United States averaged 3 hours, 3 minutes a day of screen time, up from 1 hour, 19 minutes a day in 1997, according to a 2019 research letter in JAMA Pediatrics. Some parents cite exhaustion and inability for affordable alternatives as reasons for the screen time, according to a July 2015 study in the Journal of Nutrition and Behavior.

Although the current paper looked strictly at television or DVD watching, and not media viewed on smartphones or tablets, it does provide some of the earliest data linking early-life digital media exposure with later atypical sensory processing across multiple behaviors. The authors said future research is needed to better understand the mechanisms that drive the association between early-life screen time and atypical sensory processing.

In addition to Heffler and Bennett, authors on this paper include Binod Acharya, who completed the work while at Drexel’s Dornsife School of Public Health’s Urban Health Collaborative, and Keshab Subedi from Christiana Care Health Systems.

Frequent visits to oil palm plantations are leading to a sharp increase in mortality rates among infant southern pig-tailed macaques (Macaca nemestrina) in the wild, according to a new study published in Current Biology. In addition to increased risk from predators and human encounters, exposure to harmful agricultural chemicals in this environment may negatively affect infant development.

In wild populations, infant survival is crucial for determining individual fitness and for maintaining viable populations in changing environments. For primates, agricultural areas adjacent to tropical forest habitat can be a mixed blessing: While crop plantations can provide easy access to food, they also come with increased exposure to various hazards, which is likely contributing to reduced infant survival in several wild primate species.

Exposure to palm plantations increases infant mortality

In a long-term collaboration between Universiti Sains Malaysia (USM), the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), and the Max Planck Institute for Evolutionary Anthropology (MPI EVA), researchers set out to investigate potential links between frequent visits to oil palm plantations and the particularly high infant mortality they observed among wild southern pig-tailed macaques in Peninsular Malaysia. In a habituated study population in this region, 57% of all infants born between 2014 and 2023 died before the age of one – a rate that far exceeds mortality rates reported in other wild primate populations.

For almost ten years, the researchers followed two groups of macaques living in a mosaic of rainforest and oil palm plantations. They found that prolonged exposure to oil palm plantations during infancy tripled the likelihood of infant mortality. This key finding could be explained by increased encounters with predators and humans, and potential exposure to harmful chemicals such as pesticides in this environment.

“Some of these risks are relatively clear: infant macaques are more likely to fall prey to feral dogs that roam in the plantations in packs or to be captured by humans and sold illegally as pets,” explains Dr Nadine Ruppert from USM, who established and leads the field site. “But the potential long-term effects of the pesticides used to manage the monocultures on mammalian wildlife are much less obvious and very poorly understood.”

Pesticides may affect foetal development

The study also found increased infant mortality rates when mothers gave birth for the first time or when there was a long interval between two consecutives births, which contradicts studies that report increased mortality when the interbirth interval is shorter. The accumulation or uptake of pesticides in the mother’s body may play a key role: “The literature suggests that certain harmful substances used in agriculture can cross the placental barrier and be passed on to the unborn offspring. We also know that certain fat-soluble molecules can be passed on through breastmilk,” says lead author Dr Anna Holzner (iDiv, MPI EVA, UL and USM). “Accordingly, the longer the chemicals accumulate in the mother’s body, the more they could influence foetal development during pregnancy and also during lactation.”

The study highlights the urgent need to address anthropogenic threats to animals in agricultural landscapes. “We know that the use of pesticides in agriculture has led to drastic declines in insect populations, so chemical analysis is essential to understand the effects of pesticides on mammalian wildlife,” says Professor Dr Anja Widdig (UL, MPI EVA and iDiv), senior author and leading PI in this iDiv Flexpool project. “Our findings underscore the critical need to implement environmentally friendly cultivation practices that minimise the risks to wildlife populations and also to people living near plantations.”

Exploring dimensions of justice in climate science

Peer-Reviewed Publication

INTERNATIONAL INSTITUTE FOR APPLIED SYSTEMS ANALYSIS

How can climate policy be made more just and fair? IIASA researchers have synthesized different dimensions of justice into a framework that can be used by climate scientists and policymakers, explaining how previous research has neglected many potential justice positions and how these can be implemented in policy contexts.

Dealing with climate change is not just about the environment – it is also about justice and fairness. This includes how we transition to cleaner ways of living, the different impacts on various groups of people, and who is responsible for what. Paying more attention to fairness and justice when making decisions will help policymakers to devise better climate policies that people can agree on.

Currently, people however don't always understand or talk about these concepts in the same way. While experts may think about justice and fairness when they plan ways to, for example, reduce carbon emissions, they often don't explain it clearly, instead using different words and measures, which can confuse both researchers and the public. This confusion makes it harder to share and understand the results.

In their new study published in Nature Climate Change, IIASA researchers propose a conceptual framework rooted in philosophical theory to address this gap in possibly the first systematic attempt to describe these different aspects or dimensions of justice for the climate domain in an interdisciplinary context. Their innovative framework synthesizes distributional, procedural, corrective, recognitional, and transitional justice that can be used by scientists and policymakers.

The framework aims to enhance interdisciplinary understanding of climate justice to prevent its mischaracterization and its misuse to justify delayed climate action. Recognizing that justice can either support or hinder decarbonization efforts, the researchers note that more research on justice-related issues is essential for the next cycle of the Intergovernmental Panel on Climate Change (IPCC).

“This framework aims to achieve three goals: improve clarity by using terminology from justice scholarship; promote awareness and consistency in examining justice concerns as part of a coherent whole; and enhance comparability across scenarios and modeling contexts, to facilitate discussions on these issues,” explains IIASA researcher Caroline Zimm, one of the study lead authors.

To implement this framework effectively, the authors propose the creation of a Justice Model Intercomparison Project (JUSTMIP) focused on mitigation scenarios.

“JUSTMIP would provide reporting templates for in-depth exploration of various research aspects, sectors, and model comparisons within the context of scenarios used by the next IPCC Assessment Report. This will raise awareness about the possibilities and limitations regarding justice considerations in these scenarios and enhance transparency,” notes IIASA Energy, Climate, and Environment Program Director, Keywan Riahi.

“It is important to note that our framework does not aim to evaluate what is just or unjust but rather provides a structured platform for identifying and discussing justice considerations. By bringing clarity and consistency to the discourse surrounding climate justice, this framework will empower both researchers and policymakers to navigate the intricate justice landscape and ensure that justice is a fundamental aspect of climate policy decisions,” concludes co-lead author Kian Mintz-Woo, a guest researcher at IIASA who is also associated with the Department of Philosophy and the Environmental Research Institute at University College Cork in Ireland.

This pioneering work is a significant step toward a more holistic and multidimensional understanding of justice in the context of climate change, offering a valuable tool to advance climate policy and research worldwide.

The spectacular explosion of the mine at Hawthorn Ridge – a fortified German front-line position in the First World War – marked the beginning of the Battle of the Somme, and remains one of the best-known pieces of film from the whole conflict.

More than 60ft below the surface, British miners had dug a gallery for more than 900 metres from their lines and packed it with 40,000 lbs of explosives. It was one of 19 mines placed beneath German front positions that were detonated on 1st July, 1916 to mark the start of the offensive.

But the detonation of the mine at Hawthorn Ridge, famously captured by film director Geoffrey Malins, took place 10 minutes before the whistles blew at 7.30am. The early detonation, later described as a ‘colossal blunder’, alerted the Germans the infantry attack was imminent and gave them enough time to take up defensive positions in the newly-formed crater, leading to heavy losses among the attacking British troops.

Now, findings from the first ever multi-disciplinary scientific investigation of the 107-year-old crater have been published in the Journal of Conflict Archaeology. The team of researchers, scientists and historians, led by Keele University, used a range of cutting–edge technology, including drones with imaging cameras, to examine the area like never before.

Researchers discovered and excavated two sections of trenches, known as fire bays, that were used to consolidate newly-formed craters, highlighting how the Germans successfully incorporated the crater rim into their front line after the blast. They also recovered probable communication wire and distinctive German barbed wire, and found evidence of a previously unknown shallow tunnel, believed to have been dug out from the crater by German forces to provide an advanced position in No Man’s Land. They say their findings reveal new details on the history of the crater, its capture by the Germans and how they successfully incorporated it into their front line after the blast.

Dr Jamie Pringle, a forensic geoscientist at Keele University, said: “The explosion of the mine was the very first action of the Battle of the Somme, intended to give Allied forces the upper hand. We found physical evidence for the first time of how German soldiers had consolidated part of the crater left behind after the explosion, and actually used it to their advantage as a new defensive position.”

The group were given exclusive access to the site in France after the Hawthorn Ridge Crater Association took on a 99-year lease from the local authority in 2018 to protect it for future generations. The association was set up as a Franco-British organisation dedicated to the preservation and protection of the site, and carried out extensive clearance works that provided the first opportunity for detailed study.

A second mine was blown by British forces on November 13th, causing a new crater to be formed. This explosion was much more effective, aiding the 51st Highland Division to capture the ridge and nearby village of Beaumont Hamel, which had been a prominent feature of the German frontline position.

The researchers were able to pinpoint the epicentres of the two separate mine detonation locations, and identified 27 post-explosion impact shell homes, fired from British lines as they tried to dislodge the Germans. They also found an unexploded British shrapnel artillery shell with its time-fuse still intact, representative of the large number that failed to explode on the Somme, and an empty ammunition box for a Vickers Machine Gun, reflecting the period of British occupation of the site.

Dr Kris Wisniewski, a lecturer in Forensic Science at Keele University, said: “The land had been in private ownership for almost 100 years, so this scientific study, the first to be carried out on this historically important crater, was both exciting and significant. Using a range of scientific methods, we were able to map out the epicentres of both blasts and the boundaries of the subsequent craters caused by the first and second explosions, as well as post-blast defensive positions and Allied shell impact craters.

“Using drones with imaging cameras, we were able to image remotely a probable sap or shallow tunnel to the northwest of the crater, showing the German mastery of No Man’s Land after the initial detonation.”

Professor Peter Doyle, a military historian at Goldsmiths, University of London, who was part of the team, said: “The Germans had quickly mastered the art of capturing craters and used this to their advantage. Though they lost many men in the initial blast, the crater became a part of the German frontline, meaning that the chance to break through the line here was lost.

“Our study has provided new evidence of the strongpoint the Germans built from the captured crater in the middle of No Man’s Land that doomed the British attack to failure. This reinforces the idea that blowing the mine ten minutes early, to give the earth time to settle, was a very bad idea. It was only with concerted effort four months later, and a new mine, that Hawthorn Redoubt was captured by the Highlanders.”

The research team included representatives from Keele University, London South Bank University, Staffordshire University, Atlantic Technological University, Goldsmiths, University of London, Stoke-on-Trent Archaeology Service and Cotswold Archaeology.

Transit workers go on strike in Metro Vancouver

Sat, January 6, 2024

Metro Vancouver transit workers represented by CUPE Local 4500 have begun job action on Saturday.

More than 180 transit supervisors, engineers and a range of maintenance workers within the transit system have started refusing overtime as of 8 a.m. Saturday.

The union says the job action, which followed a 72-hour strike notice on Wednesday, comes as a last resort as talks with their employer, the Coast Mountain Bus Company (CMBC), broke down. The last collective agreement expired in October 2022.

CMBC is a subsidiary of TransLink, the transit authority for Metro Vancouver.

Chris Gindhu, president of Local 4500, says some of the issues that led to the job action were fair wages and excessive workloads.

"We have proposals on the table to increase staffing levels ... and the company has so far refused to consider our solutions," he told CBC News.

Union representative Liam O'Neill previously told CBC News some of their members were "working more overtime than they work straight hours."

Gindhu says transit riders would "definitely notice" service levels drop as a result of the overtime ban, and predicted buses would run late as a result.

"Some buses won't make it into service on time [in] the depots," he said. "Some routes may be affected if the buses are not able to even leave the garage."

A Translink report lists the top 10 most complained about bus routes. Over 50 bus routes have sustained overcrowding, which is up from 38 in 2016. On-bus subjects are Laila Kott and Nizzar Kabalan, who were interviewed on the 116, the second on the list of most-complained about routes.

The union president says talks with the employer involved the efforts of veteran labour mediator, Vince Ready, but negotiations broke down. He says the union is prepared to further escalate job action if necessary.

"TransLink and Coast Mountain Bus Company plan for major expansion in the coming years, where they'll need us even more," he said. "There's a vision [to] double service in the next 10 years. And we haven't even increased staffing levels since 2012.

"Our question to them is how? How are they going to go about that?"

In a statement, Coast Mountain Bus Company president Michael McDaniel urged striking workers to return to the bargaining table with "realistic expectations."

"CMBC has made CUPE 4500 the same wage offer already agreed to by all other CMBC employees," he wrote.

"We will be closely monitoring the ongoing job action, but do not expect the union's overtime ban to have significant impacts to the delivery of transit services."

Gindhu, however, says wage equality with other TransLink employees was the issue, not the general wage increase.

The company employs almost 6,000 people in total, mostly bus drivers, according to the TransLink website.

The strike by transit workers comes on the heels of a historic year for labour action in B.C. and Canada.

Transit workers in the Comox Valley went on strike in December, following a four-month drivers' strike in the Fraser Valley over the summer.

Florida Democratic Senate candidate: 

Jan. 6 like Latin American authoritarianism


Rafael Bernal

The Hill
Sat, January 6, 2024 

Debbie Mucarsel-Powell, a former congresswoman looking to unseat Florida Sen. Rick Scott (R), compared the Jan. 6, 2021, riot on the Capitol to attacks on democracy in Latin American countries.

Ecuador-born Mucarsel-Powell, the first member of Congress born in South America, fled her birth country as a teenager with her family in 1985.

“As a South American immigrant with family still in Latin America, I’ve seen the effects of authoritarian regimes firsthand, and the fight to protect democracy at home and abroad is personal to me,” she told The Hill.

“Like so many immigrants in Florida, I came to the United States in search of the safety and stability of American democracy,” the former lawmaker added. “We’ve seen democracies attacked abroad, and I’ve watched as spineless leaders have remained silent in the face of authoritarians – but I never expected that to happen here.”

Mucarsel-Powell is in a crowded primary, though she’s posted the highest fundraising numbers of any Democrat so far.

While Scott is also facing primary challengers, he is widely expected to retain the Republican nomination and is the favorite to win the general election. But, he is perceived as the closest thing to a vulnerable GOP Senate incumbent.

Scott’s campaign did not wish to provide comment.

Mucarsel-Powell served one term representing Florida’s southernmost district, which had been notorious for flipping parties, but she lost to Rep. Carlos Giménez (R) in 2020, when Republicans made massive gains in South Florida.

That election cycle ended on Jan. 6, 2021, with the certification of President Biden’s win following the attack on the Capitol.

Since then, political divisions have grown, Republicans have won a House majority, former President Trump has taken a seemingly insurmountable lead in the GOP presidential race and campaign rhetoric has heightened, particularly against immigrants.

Trump has added references to immigration “poisoning the blood of this country” to his stump speech, drawing criticism and comparisons to former Nazi leader Adolf Hitler from the left.

Those comparisons have drawn mostly eyerolls from Trump allies, who see the left as grasping at straws to demonize the former president, though some like Giménez have softly pushed back at the rhetoric.

“Rick Scott has remained silent as Donald Trump echoed Hitler’s rhetoric,” Mucarsel-Powell said. “He defended Trump’s involvement in the January 6th insurrection.”

The former representative, who is investing heavily and early to reach Florida’s different Hispanic groups, compared his behavior to the regimes of Nicaragua, Cuba and Venezuela.

“By choosing to put party before country and standing with Donald Trump, Rick Scott is standing with dictators that destroy freedom and democracy like we’ve seen in Nicaragua, Cuba, and Venezuela,” she said. “Rick Scott is a threat to democracy, and we have to stand strong against him and these attacks.”

Republicans have had success painting Democrats in South Florida as sympathetic to those left-leaning dictatorships, but Mucarsel-Powell is using her personal experience with Latin American authoritarianism as a shield against those accusations.

“My story is like the story of so many Latinos that have come here to work hard and look for opportunities. They’re looking, actually, for safety. Many Latinos have fled political violence,” she told The Hill. “And then they come here and then they find themselves living in a country where the rise of violence continues.”

Mucarsel-Powell, whose first language is Spanish, is also making a point of appearing on Spanish-language news radio on a daily basis, tapping into the heart of South Florida’s political scene.

There, she’s been leveling attacks commonly used against Scott — including by his primary opponents — but reaching an audience that’s usually segregated from such direct contact with statewide candidates.

The Senate hopeful believes her early and bilingual Hispanic outreach is the key that will unlock Florida for Democrats after two disastrous campaign cycles.

Throughout his political career, Scott has been lambasted by attacks on his fortune’s origin, a settlement after a complex fraud case involving the company he ran, Columbia/HCA, once the country’s largest health care company.

Mucarsel Powell called that chapter “the largest Medicare fraud ever committed in the history of this country.”

Scott’s also drawn fire for his opposition to public health care programs like Medicaid and the Affordable Care Act, and has publicly butted heads with GOP leadership, even challenging Minority Leader Mitch McConnell (R-Ky.).

But Scott has proven resilient to political broadsides.

Mucarsel-Powell wants to crack that code with a bilingual delivery of attacks on Scott, her personal story, and an anti-extremism pitch.

“I’ve done everything I can to work with Republicans to serve the people of Florida. I did that as it pertained to Everglades restoration funding,” she said. “I did a lot of work with [Rep.] Brian Mast [R-Fla], trying to protect our clean water here in the state of Florida, [former Rep.] Francis Rooney [R-Fla.].”

“And always, always [I] will sit down and be willing to work with whomever wants to work, to reduce the cost of living, to help families here in Florida thrive,” Mucarsel-Powell added. “We can’t continue to have people leaving our state because they’re scared, because they can’t afford to live here.”

Avian flu H5N1 detected in polar bear in Alaska

Thu, January 4, 2024

Wildlife officials in Alaska have confirmed the first known case of a polar bear that died from avian flu — highlighting growing concerns about the H5N1 strain's potential spread among northern mammals.

Dr. Robert Gerlach, Alaska's state veterinarian, said the young bear's carcass was recently found by a biologist working in the state's remote North Slope region. Swab samples from the dead animal confirmed that it had been infected with the highly pathenogenic H5N1 strain.

"We have had birds detected with the avian influenza virus in that area. So we're making the assumption that the bear had come up onto land and had probably scavenged one of the dead or dying birds, and gotten exposed that way," Gerlach said.

The current global outbreak of H5N1 has led to the loss of millions of birds. The strain was first detected in Canada in 2021 and has devastated poultry farms, and spread to some birds of prey as well as some mammals, experts say.

Gerlach said Alaska is trying to monitor the presence and spread of H5N1 in the state, but it can be difficult in such a vast territory.

"If an animal dies, especially in the wild up here, it can be scavenged rather quickly by other animals. And so it really is a challenge, trying to find these cases," he said.

Gerlach said some bird species in Alaska have been "severely" affected by the outbreak, including eagles and magpies, as well as waterfowl.

Chickens are seen at a poultry farm in Abbotsford, B.C., on Thursday, November 10, 2022. Poultry farmers and wildlife officials in British Columbia's Fraser Valley are reporting "extremely high" levels of stress and anxiety as the latest avian flu outbreak puts millions of birds at risk.

He said this outbreak seems much different to the last global outbreak of avian flu nearly a decade ago. The previous one "seemed to dissipate rather quickly," Gerlach said.

"In this case, we are seeing it really hang on and being adaptive to stay very influential in wild birds, as well as impacting you know, our domestic poultry."

H5N1 can also infect humans, though such cases are rare and "mostly occur after close contact with infected birds or highly contaminated environments such as poultry farms or live bird markets," according to Health Canada.

Still, Gerlach says it's hard to predict how the global outbreak will evolve. Some scientists worry that it could eventually turn into another pandemic among humans.

"Currently the risk to people is very, very low," Gerlach said.

"But as this virus adapts or mutates, will it change and cause more of a problem? And that's one thing that it's going to be very important that animal health and public health officials work together to study and understand this virus, to go ahead and be prepared."

Tracking infections 'certainly is a challenge,' says Yukon vet

Across the border in the Yukon, territorial veterinarian Jane Harms said she wasn't surprised to learn of the infected polar bear in Alaska given the virus's spread among mammals elsewhere.

Yukon, however, has not seen much evidence of infection in the territory's wildlife so far. Harms said the last known infection was in a wild bird last April. There has also been one known case in a red fox, a little over a year ago.

As in Alaska, it can be hard to track infections in the territory's remote regions, Harms said. Wildlife officials often rely on members of the public to notify them of any sick or dead animals they see while out on the land.

"But it certainly is a challenge," she said.

Harms said the greatest concern right now is for wild bird populations, because it's clear the disease can be transmitted easily from bird to bird.

The risk of widespread, ongoing transmission between mammals is less clear, she said.

"I don't think we've ever seen quite this scope in terms of the number of mammals that have been infected or the range of species. And so we now can add polar bears to that list — but it's already getting to be a fairly long list and that's relatively unprecedented," she said.

"And anytime you have a situation that's sort of unprecedented with regard to wildlife health, that is definitely of concern and something that we are are watching quite closely."

The provincial government announced Wednesday its spending $700,000 over five years to prevent conflict between ranchers and large carnivores in southwestern Alberta.

Funds will go to the Waterton Biosphere Reserve Association's Carnivores and Communities Program to keep predators away from rural properties.

Residents in the area have expressed concern about growing grizzly bear, wolf and cougar populations and their impacts on community safety, says the province.

"Coexisting with wildlife, including large carnivores, is an everyday part of living and working in rural Alberta," said Alberta's Minister of Forestry and Parks Todd Loewen in a statement.

"This investment will help protect humans, wildlife and infrastructure."

The majority of human-wildlife conflicts in the Waterton Biosphere region are attributed to wolves and grizzlies, according to the reserve association.

Conflict arises because the animals are attracted to livestock, grain and animal feed, and roam onto farms to chow down.

Dead livestock disposal and electric fences

To keep the carnivores away, the Waterton Biosphere Reserve Association has helped farmers manage attractants by picking up dead farm animals for free and pointing people to carcass-disposal bins in their area.

"Across the region, I'd say we've seen a generally positive trend," said Carnivores and Communities Program co-ordinator Jeff Bectell. "But it's not perfect and not 100 per cent [successful]."

The CACP also advocates for strategies to keep away grizzly bears based on landowners' specific needs, like livestock guardian dogs or horseback herd supervision.

If necessary, the program also helps farmers pay for electric fences or more secure grain bins to quash access to food sources.

"We don't do the same project on every property because different people have different needs in terms of the amount of stuff they're storing, how they access it," said Bectell.

"There's just lots of differences from one farm to another and so it is pretty customized."

A Grizzly bear and cubs were spotted alongside Highway 40 in Peter Lougheed Provincial Park on June 15, 2021, the day the road to Highwood Pass reopened for the summer.

Grizzlies moving further east

In the past several decades, grizzlies bears have been recorded farther east in southwestern Alberta, outside their expected range.

Wildlife ecologist Andrea Morehouse, who has worked under contract for the Waterton Biosphere Reserve Association, says the easterly bears are exposing more farmers to the potential for human-wildlife conflicts.

"If you're not used to ranching with grizzly bears, it's certainly a new problem that you need to figure out how to deal with, and learn ways to share the landscape with those critters," she said.

"That's part of what the Carnivores and Communities program is doing … helping to find creative solutions so that people are able to maintain their business, ranchers can still do what they need to do, but bears are also maintained on the landscape."

Morehouse said the most current data on grizzly bears in the Waterton Biosphere region, collected from 2011 to 2014 for her Southwest Alberta Grizzly Bear Monitoring Project, showed the population was growing, which could be why some are ranging farther east.

Bectell said the funds will help rural ranchers feel supported and appreciated for their contributions to the province.

"Landowners dealing with these kind of problems sometimes feel alone," he said.

"When funding like this is provided, that does come out of the public purse, I think it demonstrates to agricultural producers that they're not being left alone and ignored."

The Alberta government has supported the Carnivores and Communities Program through different grants since 2009.

Court decision barring Chinese student sends message about espionage risk, experts say

In a decision that could have ripple effects on universities across the country, a Federal Court judge has denied a Chinese resident permission to enter Canada, arguing the engineering student could be pressured by Beijing into spying.

The case centres on Yuekang Li's visa application to study at the University of Waterloo and take his knowledge back to China to improve its public health system. Federal Court Chief Justice Paul Crampton ruled Li's proposal falls under the definition of "non-traditional" espionage.

"As hostile state actors increasingly make use of non-traditional methods to obtain sensitive information in Canada or abroad, contrary to Canada's interests, the court's appreciation of what constitutes 'espionage' must evolve," he wrote in his December 22 decision, made public this week.

Margaret McCuaig-Johnston, a board member with the China Strategic Risks Institute think-tank, said she expects to see more such rulings in future.

"[Canadian] visa officers in Beijing and likely in other cities in China have been given some guidance as to what to watch for, potential military connections with students and professors who want to come from China to Canada and work with our own professors," she said.

"This is new and I think it's something then that universities themselves need to be watching, [to avoid] admitting students who may be a security risk."

According to the decision, first reported on by the Globe and Mail, Li applied for a study permit in 2022 after the University of Waterloo accepted the PhD candidate into its mechanical and mechatronics engineering program.

He was deemed inadmissible. A visa officer later stated he had multiple concerns with Li's application, citing his anticipated field of study while in Canada and China's use of students as "non-traditional collectors of information" to boost China's research into new technologies, including military tech.

"The officer further noted that Mr. Li has a strong interest in microfluidics, a branch of micro/nanoscale science and technology, and that he indicated in his study plans that he wanted to dedicate his career to improving China's underdevelopment of the application of advances to point-of-care technology in the field of public health," says the Federal Court decision.

The visa officer, who was not named in the decision, pointed to China's strategic interest in certain high-tech industries, including biopharmaceuticals.

The officer cited an article titled "Why is China Becoming a Microfluidics Superpower?" — which says microfluidic devices are important for new medical research — in support of his decision to reject Li.

Judge sided with visa officer

Li asked a judge to review that ruling. He argued the officer went with an overly broad definition of "espionage" and relied on speculation, says the Federal Court decision.

Justice Crampton sided with the visa officer and said there are reasonable grounds to believe that Li may be recruited or coerced by the Chinese government as a spy.

The judge pointed to Li 's studies at a Beijing university with ties to China's defence industry, the fact that Li's field of study could benefit China's biopharmaceutical industry and China's well-known history of targeting scientists and students.

Dick Fadden, former national security adviser to the prime minister, said the decision offers Canada a new tool to "get a grip" on a growing problem.

"Whether or not Mr Li is or could be a spy is neither here nor there. I think that it's beyond reasonable debate that the Chinese, both in Canada and in allied countries, have used universities as a means of acquiring intellectual property of use to their military," he said.

The decision comes as concerns mount over China's interest in Canadian universities and research programs.

The Canadian Security Intelligence Service has been sounding the alarm publicly. Just last month, the spy agency's director David Vigneault warned in a speech that no one should underestimate China's efforts to steal Canadian research and meddle in its affairs.

"They are stealing the intellectual property of Canadian businesses, universities and governments – the very essence of our future prosperity," he said in a speech delivered at the Canadian Museum for Human Rights in Winnipeg.

"No one should be under any illusion about the breadth of [China's] efforts to infiltrate our political systems, our private sector, government institutions, universities and communities from coast to coast to coast. This is not just a Vancouver or Toronto issue. It's an all-of-Canada one."

Fadden, a former CSIS director, said it's past time to consider sealing off some areas of study from foreign adversaries, including nuclear technologies, high-level optics and space research.

"We should promote bringing other country's students to this country as much as we should encourage Canadians to study abroad, but surely there must be a certain number of critical areas where we and our allies have decided we do not want to share with a strategic adversary," he said. "I think this judgment will make it easier to do this.

"I also hope we are not going to do it holus-bolus and start banning everybody. But I come back to my point about the ten or 15 critical areas, dual-use and military, where I think if you give individual visa officers and individual security officers the capacity to check people doubly in the context of these decisions and these areas, it is a good thing for Canada."

Canada an easy target: China expert

The federal government has introduced national security reviews for academics seeking federal funding from the Natural Sciences and Engineering Research Council and has promised to clamp down on Canadian universities collaborating with Chinese scientists, especially those with links to China's military.

"I still think we're behind," said Fadden. "Because we were very slow in coming to this. I think probably one of the biggest challenges that we face is to acknowledge that national security is no longer the sole purview of the federal government. You have to involve the provinces, you have to involve civil society and the private sector."

McCuaig-Johnston said China has targeted Canada's campuses for years because "we are easy to get into."

"We don't want to be attracting military scientists to work in Canada, partnering with government funded programs to learn our innovations and use them for their own military applications," she said. "That's not very wise. And so, we need to close that back door."

David George-Cosh, a spokesperson for the University of Waterloo, said the university is reviewing the language of the court decision "as it contains helpful guidance on the government's interpretation of risk that will help us in assessing applicants in future."

Currently, CSIS is restricted to sharing classified intelligence only with the federal government. CSIS has long argued that its enabling law needs to be revised so it can better warn other institutions, including universities, businesses and Indigenous governments, of national security threats.

The federal government is in the midst of consulting on potential amendments to the CSIS Act. George-Cosh said Waterloo hopes an amended CSIS Act could "allow the service to share more information with institutions like universities ... so that we can more effectively evaluate our activities."

Neither Li's lawyer nor the Chinese embassy responded to CBC's request for comment.

In the past, the Chinese embassy in Ottawa has told CBC News there is nothing to fear from scientific collaboration with China.

"China believes that international cooperation is an inevitable requirement for scientific and technological development," an embassy official told CBC back in 2020.

Fadden said China doesn't respect its own rhetoric on international scientific cooperation.

"There's another principle involved here. In international relations it's called reciprocity — that if we allow them to do x, they should allow us to do x," he said.

"If you look into what the Chinese allow, I think you'll find that very few westerners are allowed to study at Chinese universities looking into those 10 or 15 categories I'm looking at."

Retail collectives are changing how young entrepreneurs access storefront selling space

ITS CALLED A FLEA MARKET

Collective retail spaces are changing the way young entrepreneurs are getting their brands in front of customers.

One local business owner says the retail collective model is helping Calgary's artist and creative community break into the physical retail space.

Five years ago, Alice Lam opened her first collective store called Tigerstedt and Friends, on Centre Street North, and she says this has been a successful model.

"Two of the businesses there grew so much that they ended up taking over the entire store."

Collective retail spaces are shops where local entrepreneurs can rent a shelf or sell their goods in a consignment-style arrangement, which many vendors say eliminates some of the biggest barriers of opening a business — especially for young people.

But the idea of a collective retail space isn't a new invention. Collective retail stores are popular in many major cities, which is what inspired Lam to bring it closer to home.

"Being a business owner myself, I know it's very hard to take on all the financial risk of opening a storefront by yourself, and so I really was attracted to this community model," said Lam.

Following the first storefront's success, Lam then co-founded Moonlight — a second collective retail space, but this time in downtown's Dragon City Mall — which opened in November.

"It's just a chance to build up the entrepreneurial community among young Asian makers in Calgary, and it's a way for us to also revitalize Calgary's Chinatown and contribute to this community that we grew up enjoying so much."

According to the co-founder, the median age for Moonlight's vendors is under 30.

Lam says the name "Moonlight" came from the idea that collective retail could help young entrepreneurs test their business model, products and passions before diving head first into the career path.

"I think it allows them to moonlight as something that they'd like to try," said Lam.

"It allows you, whether you're in school or you're working full time, to kind of have a platform to pursue one of your passions and figure out, 'is this something that I want to pursue in the future?'"

Lam says she was shocked by how many people wanted to participate — from tea and trinkets to ceramics and candles, the collective retail spaces house goods from nearly 50 local vendors.

One of the vendors at Moonlight is 19-year-old Deni Hui, who owns Dear Bearie, a business that specializes in handmade polymer clay trinkets, earrings, charms and more.

Hui says the collective retail space is a game changer for small businesses, especially when it comes to the overhead capital that young entrepreneurs might not have access to.

"To invest in a store is a very big risk to take, especially if I'm just selling little things like this. Like, how am I going to make enough to cover all of these shelves and fill up an entire store?"

One of the things that makes this experience so unique is being able to meet other vendors and share the highs and lows of being a small business with one another.

"I think a shop like this brings together so many people and it's just one solid place that we can all meet," she said.

"It's like a little library of people."

And it's not just about the other retailers. Hui says it also gives customers better insight into what they're buying before their purchase, something she believes e-commerce lacks.

"Actually seeing people go, 'Oh my God, it's so cute,' is what really makes me so in love with this kind of place," she said.

Right now, Hui is selling her products only at Moonlight, but she says collective retail is groundbreaking for small businesses and she hopes to get into more collective storefronts in the future.

But the collective retail space isn't new to every small business owner. Lucy Tan owns Lavish the Label, a handmade jewelry company, and she sells her products in two of Calgary's retail collectives.

Tan's jewelry is sold in both Moonlight and another retail collective located in Chinook Centre. She says the collective retail format takes some of the burden off of small business owners.

"It also kind of allows me to grow like the channels at which I distribute, which makes it easier on me," said Tan, adding that not having to spend a whole day standing at a market selling her product is a key benefit of the collective model.

But it's also about growing a business and connecting with people who may not know your products exist.

She says collective retail expedites the process of gaining brand recognition "because there are shoppers who just come into the store already."

And Craig Patterson, the founder and publisher of Retail Insider, agrees.

"People are still physically going into the malls or stores.… So these smaller brands can get a physical presence in a place where people may already be looking for those things."

And the in-person experience offered by a retail storefront is something Patterson believes is making an important comeback.

"More people shifted online during the pandemic to shop, but we've seen online shopping levelling off and we've seen people still going into stores over the holidays," he said.

He says collective retail shops function like a department store. It's like a collaboration involving different products, brands and businesses. However, instead of mass production and big conglomerates, what's attractive about the retail collective is its local vendors with one-of-a-kind products and a low environmental impact, says Patterson.

"A lot of people are kind of tired of the mainstream products you can just get anywhere. If you're looking for something unique, you can go to one of these smaller retailers that's a bit more localized and find something you may not be able to get anywhere else."
