The United Food and Commercial Workers (UFCW) Local 401 is concerned about rising COVID-19 case numbers in Alberta and pandemic fatigue or complacency.

"The second wave of this pandemic is in full swing," union president Thomas Hesse said in a news release Monday.

"We are seeing a sharp increase in positive COVID-19 cases and further workplace outbreaks, including multiple cases at a Superstore in Calgary.

"These trends are terrifying, especially for workers who are still being told they are too essential to 'stay home' and that they no longer deserve pandemic pay premiums."

On Tuesday, Alberta Health confirmed, on average, 567 new COVID-19 cases per day over the last four days. The total number of active cases in Alberta hit 6,110 Tuesday. Dr. Deena Hinshaw said Alberta’s positivity rate has risen to 6.8 per cent.

In March, grocery chains across Canada temporarily raised wages.

Sobeys paid frontline workers in stores and distribution centres $50 more a week, regardless of number of hours worked. Workers with 20 hours or more a week received an extra $2 an hour.

Loblaws temporarily raised wages by an estimated 15 per cent, while Metro raised wages by $2 an hour.

However, most of those pandemic payments were scaled back or eliminated by summer.

With the coronavirus a part of Canadians’ lives for more than three months, Loblaws stores and distribution centres “have settled into a good rhythm,” Sarah Davis, Loblaw president, wrote in an email to workers sent on June 11 and obtained by the Canadian Press.

“With this stability and economies reopening, we have decided the time is right to transition out of our temporary pay premium.”

"Essential workers have been told they must come to work to provide key services to the public," said Karamjit Ryan, a UFCW member working at a Safeway pharmacy in Edmonton. "When the company took away pandemic pay, we felt like we went from 'heroes' to 'zeroes.'"

UFCW Local 401 says that 67 Alberta worksites represented by the union have been impacted by positive cases so far, ranging from a single case to more than 950 cases at a single site, most notably at Cargill High River. The union said it's seen "a sharp uptick" in reported cases in recent weeks.

As of Tuesday, Alberta Health said there were outbreaks at Fairmont Jasper Park Lodge, a Walmart Supercentre in Grande Prairie, Canada Bread Company in Edmonton, Hello Fresh warehouse in Edmonton, Maple Leaf Poultry in Edmonton, Loblaw Freeport Distribution Centre in Calgary, Goodfood Market in Calgary, the Westwinds Real Canadian Superstore in Calgary, Harmony Beef in Rocky View County and Cavendish in Lethbridge.

The union also wants to see province-wide regulations. It says the face-covering bylaws and physical distancing rules are "often unenforced at the store level" and "left up to front-line workers to enforce," Hesse said.

Michael Hughes, the communications coordinator for UFCW Local 401 told Global News it sent a letter to Premier Kenney on April 23, outlining safety standards and precautions the union wanted to see across Alberta's food industry.

The letter asked the province to, among other things, create a working group of labour, employers and health experts to set rules to protect workers in all food sector workplaces, immediately close worksites for 14 days when there's an outbreak and have employees isolate and be tested.

The letter also asked that hazard pay remain while the pandemic does and that employers offer paid leave for all workers who cannot work due to COVID-19.

Hughes said the union has heard "nothing" back from the government.

"The Alberta government was pretty busy acting to ensure flexibility for employers... but what they haven't done is ensure certain protections for food workers."

In a statement, a spokesperson for Alberta's ministry of labour said the government recognizes "the tremendous work of all Albertans throughout this pandemic."

When it comes to pandemic pay, the province put $170 million towards long-term care and supportive living sites' staffing and supports.

"The funding supports topping up the wages of 12,000 health care aides by $2 an hour for the duration of the pandemic, increasing health care aide staffing levels by the equivalent of 1,000 positions, and providing paid practicums to fast-track another 1,000 health care aide students into jobs in continuing care facilities," ministry spokesperson Adrienne South said.

"The province remains committed to providing support for all health care aides that work in contracted facilities, including the many community-based, non-profit facilities."


The union said it's tried to seek change through the companies themselves, with little success.


"We've asked employers to fix these things. That's our first go-to," Hughes said.

"Obviously we've gotten nowhere with them. They're resistant to bring back these types of premiums."

Global News has called and emailed Loblaw Companies and Sobeys Inc. for a response to the union's call. This article will be updated if we receive a comment.

Hughes said Alberta has seen two of the largest outbreaks in Canada -- at the Cargill and JBS processing plants -- and the union wants the province to regulate safety precautions and investigate the cause of the outbreaks.

"We should feel ashamed at what happened at these plants... While the pandemic pay has been scaled back and basically put on the shelf by a lot of these employers, we're still facing the same risks," he said.

"It blows our mind that as the numbers increase to levels higher than they even were in the spring, employers are seeing cause to ease rules that were put in place to keep employees safe," Hughes added.


"Even if it means less production, protect those employees."

However, a spokesperson for Cargill stressed its safety protocols, many of which have been in place since March, have certainly "not been relaxed at any point as we remained focused on our employees' safety," Daniel Sullivan told Global News.

He said Cargill has worked with local health authorities to implement safety measures at facilities across Canada.

"This summer, we've added an additional 6,500 square feet of space to our cafeteria in our High River facility to allow for greater social distancing in common areas in anticipation of colder weather as well as expanded locker rooms for both men and woman along with additional washrooms," Sullivan said.

JBS said it continues to recognize employees during the pandemic "through a financial bonus program." The company also gave $2 million to support the community of Brooks.

JBS spokesperson Cameron Bruett said the company has implemented "hundreds of safety interventions to protect our workforce and support our community, including screening and temperature checking all employees prior to entering the facility, staggering start times and break times to promote physical distancing, requiring the use of masks and face shields, erecting physical barriers where possible, installing UV germicidal air sanitation and plasma bipolar ionization technologies to neutralize potential viruses in the air, and removing vulnerable populations from our facilities with full pay and benefits."

Bruett said JBS had maintained all preventative measures and added more, including "new building structures to accommodate more social distancing during lunch and other breaks."

What happens to N.W.T. patients if Alberta hospitals are overwhelmed?
Sara Minogue CBC
© Codie McLachlan/CBC As COVID-19 cases escalate in Alberta, health officials in the N.W.T. have been assured that the agreement that allows for N.W.T. patients to travel south and access Alberta medical facilities like Edmonton's Royal Alexandra Hospital, will…

On Oct. 28, doctors from the Edmonton Zone Medical Staff Association wrote an open letter warning the local health-care system was at a "tipping point," citing record-high COVID-19 case counts and hospitalization rates.

That was almost a week before Alberta's chief medical officer of health announced that 2,268 cases had been logged in the previous four days, and said the province was at a "critical juncture."

The situation in Alberta is still not as dire as it is in Manitoba, where hundreds of doctors have warned that the health-care system is strained.

Manitoba's rising caseload prompted a warning from the Nunavut government on Oct. 31 that scheduled medical travel for people in the Kivalliq region, who rely on Manitoba medical services, could be affected. The health department said staff would review all scheduled travel and notify individual patients about possible cancellations.

Though the number of cases is higher in Alberta, it has more than three times the population of Manitoba, fewer COVID-19 cases per capita, and more health care available generally. © CBC News This chart tracks the daily COVID-19 cases reported in Alberta (in grey; top line) and Manitoba (in green; bottom line) since early October. Manitoba has fewer cases than Alberta, but its health-care system is closer to being overwhelmed. That's in part because Alberta has more than three times the population.

People in the territories rely heavily on Alberta for health care.

In addition to scheduled medical appointments, data from the Canadian Institute for Health Information shows that in 2019-20, N.W.T. residents were admitted to hospital overnight in Alberta's Edmonton zone 955 times. The previous year, that number was 1,004. Both numbers are a tally of "acute inpatient hospitalizations," or hospital stays that were not scheduled ahead of time, and can include patients who were admitted more than once.


In addition, N.W.T. patients received 522 day surgeries in Alberta's Edmonton zone in 2019-20, and 721 the previous year. 

Urgent services a priority

The N.W.T. Health and Social Services Authority (NTHSSA) has a longstanding agreement with Alberta in which N.W.T. residents are considered equal to Alberta residents in terms of access to services.

"[Alberta Health Services] has confirmed that this relationship will continue to be honoured as we move through the evolving pandemic situation," authority spokesperson David Maguire said in an email.


Maguire also said the authority has been closely monitoring the situation as cases have "escalated in recent weeks."

"The NTHSSA remains in close contact with counterparts in Alberta, as recently as last Friday [Oct. 30], and to date they have not advised of cancellations or reductions in booking of elective appointments or procedures or access to emergency care services," Maguire said.

Virtual care is already being used whenever possible, he added.

"Urgent critical services will always be a priority," said the N.W.T.'s Chief Public Health Officer Dr. Kami Kandola in response to a question about out-of-territory care during a weekly COVID-19 briefing with reporters Wednesday.
Planning for the worst

The N.W.T.'s COVID-19 pandemic response plan operates on the explicit assumption that "the ability for Alberta to accept patients for transfer may be limited."

The plan envisions preparing to activate "external resources," such as field hospital supports, once about half of the 24 COVID-19 inpatient beds at Stanton Territorial Hospital are full.

Throughout the plan, it emphasizes efforts to "flatten the curve" to prevent the widespread illness.

Dr. Deena Hinshaw, Alberta's chief medical officer of health, has also offered assurances that health services will remain available and accessible.

"While COVID[-19] has consumed much of our attention in our lives, we must not forget that babies are still being born, accidents are still occurring, and Albertans continue to experience a wide range of urgent health needs," Hinshaw said Tuesday.

"Our top priority is protecting the health system to ensure that COVID-19 does not threaten our ability to provide the essential care that Albertans require for all their health issues."

Hundreds of coal mining jobs to end as power company switches to natural gas


CALGARY — Alberta power producer TransAlta Corp. says it will end operations at its Highvale thermal coal mine west of Edmonton by the end of 2021 as it switches to natural gas at all of its operated coal-fired plants in Canada four years earlier than previously planned.

The announcement will result in hundreds of mine job losses as employment drops to 40 to 50 people involved in reclamation work, expected to take about 20 years, from a peak workforce of around 1,500, said CEO Dawn Farrell on a conference call on Wednesday.

TransAlta confirmed last week it had closed a $400-million second tranche of a $750-million investment by an affiliate of Brookfield Asset Management, with the proceeds to be used to advance its coal-to-gas conversion program and other corporate purposes.

But on the call, Farrell said Brookfield's purchase of convertible securities wasn't responsible for the board's decision to accelerate its coal-to-gas conversions.

"It's really related to, overall, the economics of producing power in Alberta on coal with the carbon tax," she said on the call.

"We've currently got a $30 (per tonne) carbon tax, it'll be $40 by next year, $50 the year after. Coal plants get less economic and they're less flexible in a merchant market."

The percentage of power in Alberta generated from coal has fallen from more than 80 per cent in the 1980s to less than one-third now, in part due to rising provincial government prices on carbon that began in 2007. The electricity market was deregulated in 1996, which means prices are set through competition.

"It's good news for GHG reduction and the health of Albertans to have coal being phased out earlier," said Binnu Jeyakumar, director of clean energy for the environmental Pembina Institute, adding coal power profitability is becoming less attractive as the costs of renewable power fall.

She cautioned, however, that converted coal plants are unlikely to be as efficient as new natural gas powered plants and added that fugitive gas emissions from production and transportation of gas also present an ongoing GHG risk.

TransAlta said it will stop burning coal in its Keephills Unit 1 and Sundance Unit 4 plants, which will operate at lower capacity with natural gas, while it evaluates full conversion projects.

A conversion project at Sundance Unit 6 is to be complete in a few weeks and the conversions of Keephills Unit 2 and Unit 3 are to be wrapped up in 2021.

The company announced it will proceed with the full $800-million conversion of Sundance Unit 5 to allow it to produce about 730 megawatts when it comes online in Q4 2023.

"Our greenhouse gas emissions will be under 11.5 million tonnes by the end of 2022, down almost 70 per cent from 2005," said Farrell, who said it has cut 32 million tonnes per year across its worldwide operations since 2005 and 21 million in Canada.

"TransAlta has more than met it's fair share of the Paris agreement. To date, we alone have delivered 10 per cent of Canada's goal of a 220-million-tonne reduction for Canadians by 2030."

She said TransAlta should be a "sought after investment" for clean energy investors.

The company will still produce power from coal at its Centralia facility in Washington State, which has a transition agreement allowing it to burn coal until its end of life in 2025, Farrell said on the call.

TransAlta also owns a 50 per cent stake in the Sheerness power plant in western Alberta, which is operated by American firm Heartland Generation Ltd., and continues to burn coal although it has some dual-fuel capabilities.

TransAlta reported a loss attributable to common shareholders of $136 million for the quarter ended Sept. 30 compared with a profit of $51 million in the same quarter a year earlier.

Revenue was $514 million, down from $593 million in the same quarter last year.

TransAlta to end coal mining operations at Highvale in 2021, stop using coal in Canada

Lisa Johnson 

TransAlta Corp. says it will stop mining coal at its Highvale mine by the end of 2021 and will no longer use coal to generate power in Canada effective Jan. 1, 2022.

A giant drag line works in the Highvale Coal Mine to feed the nearby Sundance Power Plant near Wabamun on Friday, Mar. 21, 2014.

In a Wednesday report of its third-quarter financial results, TransAlta said it was closing the mine, which is located south of Lake Wabamun, about 70 kilometres west of Edmonton, four years ahead of schedule in an effort to accelerate its environmental, social, and corporate governance goals.

The Highvale mine, which has been in operation since 1970, is one of three TransAlta-owned surface coal mines and Canada’s largest surface strip coal mine, covering more than 12,600 hectares, according to the Calgary-based company’s website.


TransAlta CEO Dawn Farrell said in a conference call that the company is on track to reduce its greenhouse gas emissions by almost 70 per cent from 2005 levels by the end of 2022.

“TransAlta has more than met its fair share of the Paris Agreement,” said Farrell.

Under the agreement, Canada committed to reducing its emissions by 30 per cent below 2005 levels by 2030.

At TransAlta’s coal power generating stations, Keephills Unit 1 and Sundance Unit 4 will stop firing with coal and will only operate on gas, reducing their maximum capability to 70 MW and 113 MW, respectively.

“It’s really related to overall the economics of producing power in Alberta on coal with the carbo
n tax. If you look at Alberta, we’ve currently got a $30 (per tonne) carbon tax, it’s be $40 by next year, $50 the year after. Coal plants get less economic and they’re less flexible in a merchant market,” said Farrell.

TransAlta reported a net loss attributable to shareholders of $136 million for the quarter ending Sept. 30, compared with a profit of $51 million in the same quarter last year. The difference means a loss of 50 cents per diluted share this quarter, compared with a gain of 18 cents in the same quarter of 2019.

The company said the decrease was largely due to lower revenues, a write-down of its coal inventory, higher depreciation, and an increase in asset impairments and power purchase agreement termination payments, which were partially offset by foreign exchange gains and income tax recoveries.

Its revenue for the quarter was down to $514 million from $593 million in the same quarter last year.

TransAlta operates more than 70 power plants in Canada, the United States and Australia.






Conservation group says regulatory gaps in Canadian seafood supply chain pose threat


HALIFAX — An ocean conservation organization says Canada's “poorly regulated” seafood supply chain has hampered the fisheries sector and put ocean health in jeopardy.
© Provided by The Canadian Press

In a report released Thursday, Oceana Canada says the regulatory gaps are unwittingly contributing to illicit seafood fishing and trade.

“You could be buying something that says 'Product of the United States' but in fact, it was fished in a completely different country,” Sayara Thurston, the group’s seafood fraud campaigner and author of the report, said in an interview.

Global seafood supply chains are notoriously complex, Thurston said, making it difficult to track seafood to its place of origin and all too easy for “illegal, unreported and unregulated” products to make their way to Canadian retailers.

A previous Oceana Canada study found that Canada’s “insufficient labelling requirements” had led to significant mislabelling of seafood products.

Of 472 seafood samples collected from Canadian grocery stores and restaurants, nearly half were mislabelled. In part, that's because the place of origin on seafood products may only suggest the last place the product was processed, which is allowed under Canada’s current standards, she added.

The report calculates that the illicit seafood trade in Canada results in lost tax revenues of nearly $94 million, as unreported catches equal an estimated 14 per cent of the $3.9-billion annual landed value for marine fisheries.

The group also found Canadians are spending up to $160 million annually on seafood caught via undocumented fishing.


Thurston described the use of “modern slaves” in the global unregulated fish trade, which she said can involve the kidnapping and coercion of undocumented workers. Illegal fishing can also have drastic effects on fish populations as certain species can quickly become overfished.

The advocacy group is calling on the federal government to make good on its previously announced commitment to create a "boat-to-plate" traceability program, which would allow tracking of seafood from vessels and farms right though the supply chain to retailers.

In a letter released in December 2019, Prime Minister Justin Trudeau mandated Minister of Health Patty Hajdu, who oversees the Canadian Food Inspection Agency, and Fisheries Minister Bernadette Jordan to collaborate on a tracking system.

According to the report, however, the ministries have yet to set a timeline to develop a system.

Some of Canada’s largest trading partners have already tackled the tracking issue, Oceana argues, including the United States and the European Union.

“What we're looking for is for Canada not to be left behind on this issue, to keep up with the global trend of increasing transparency in the seafood supply chain," Thurston said.

Dying for movies: Suicide highlights labour issues in Canada's visual effects sector


MONTREAL — Last April, Malcolm Angell, a 41-year-old New Zealander who moved to Montreal to work in the city’s famed visual effects industry, was taken to hospital after attempting suicide.
© Provided by The Canadian Press

He was back at work two days later at Montreal-based visual effects studio Mill Film, according to his brother, Ivan. A month later -- shortly after learning his mother had a brain tumour and didn’t have long to live -- Angell tried to kill himself again. This time he died.

Angell's former colleagues allege the work environment at Mill Film was toxic. They say 80-hour workweeks were common, and that Angell was regularly humiliated by his bosses. Ivan says he's certain his brother would have quit -- were it not for a clause in Angell's contract requiring he pay a $35,000 penalty.

The story told by Angell’s colleagues is not uncommon in Canada's visual effects and animation sectors, according to industry insiders. Long overtime hours, often unpaid, are seen as normal, they say. And employees in these industries are vulnerable -- particularly foreign workers -- who toil on short-term contracts and are afraid to speak up out of fear of not getting hired again.


For Vanessa Kelly, a former animator and union organizer in Vancouver's animation industry, Angell’s suicide is a sign that something is deeply wrong with the visual effects sector. She said similar issues exist in animation and within video game companies across Canada.

“These are movies. Why are people dying for movies?" said Kelly, general director of the Art Babbitt Appreciation Society, which is trying to organize animators in Vancouver.


Angell had nearly 20 years experience in film, and got his start working on set during the production of The Lord of The Rings. In August 2019, he moved to Montreal to work in the city’s visual effects industry -- one of the largest in the world. Colleagues and friends say it was not long before the job started to get to him.

The Canadian Press spoke to three of Angell’s former colleagues, who painted a picture of a workplace where Angell was under extreme pressure and where bosses yelled at him during meetings. Complaints to human resources and to senior mangers, they said, went nowhere.

The Canadian Press has agreed not to identify those workers because they fear repercussions. All three said people in the industry who speak out against work conditions are frequently blacklisted.

“Work kinda sucks,” Angell wrote in an email to a friend in New York City in early September 2019. By November, in an email to the same friend, he said he was doing the work of two people. A planned trip to New Zealand for a wedding in February, 2020, was cancelled, his brother Ivan said in a recent interview, because Angell couldn’t get the time off work.

Ivan Angell said friends noticed a change in his brother by December. The man who was described in an obituary as a “superfriend” who was always smiling, had become a “shadow of himself,” he said.

Julia Neville, with the International Alliance of Theatrical Stage Employees, said fears of being blacklisted for speaking out in the visual effects industry are legitimate. Visual effects artists are precarious workers, Neville said, because their contracts are typically for one project at a time. “There’s always that underlying insecurity,” she said. Foreign workers, such as Angell, are “particularly vulnerable."

“They can’t just cross the street and work for another visual effects house -- their whole ability to work in Canada is tied to a specific employer,” Neville said. Much of the film industry is unionized, while the large majority of visual effects artists are not, she explained. Long hours and unpaid overtime “are very common,” she said, adding that unfair labour practices are frequent in other entertainment sectors, such as animation, reality television and in commercials.

Neville said visual effects companies try to underbid each other for work on projects produced by major movie studios. "That pressure is exerted downward onto the worker," she said. "What ends up happening is there’s never enough time allotted to accomplish what you need done.”

Angell’s former colleagues said he was under extreme pressure to complete his part in the movie "Bios," starring Tom Hanks. They said Angell and the team he oversaw had been told by his bosses at Mill Film to finish additional work but hadn't been given more time or money to get it done.

Another element that tied Angell to his employer was his contract, a copy of which The Canadian Press viewed. The contract included a clause stating he was liable to pay Mill Film a $35,000 indemnity should he leave in the middle of a project.

The indemnity clause identified Angell as a “key member” of the team and indicated that the company would be contractually committing Angell's services to its client. The contract said that for “certain very exceptional and serious" reasons the company could decide to waive the indemnification clause.

Adelle Blackett, a law professor at McGill University and labour law expert, said that clause “is deeply disturbing.” Quebec's labour standards require employers to provide working conditions that "safeguard employees’ dignity, health and well-being,” she wrote in an email. “An employee working in conditions of freedom must be able to terminate an employment contract with only minimally necessary restrictions.”

Technicolor, Mill Film’s parent company, did not make anyone available to speak on the record. In an emailed statement, the company said Angell’s death was a “traumatic and tragic event for his family, friends and for our team. We mourn his passing and continue to express our deepest condolences to his family.”

The company said it has introduced a new program aimed at supporting employee mental health since Angell’s death – due to the “severity and isolating nature of the pandemic.” Another program has been launched encouraging employees to “call out” inappropriate behaviour, the company said.

“Technicolor has had longstanding and robust anti-harassment policies in place in Canada. This specifically includes broad anti-bullying and related anti-retaliation policies, among others,” it said. The company said it takes complaints seriously and that it didn’t receive any formal complaints about Angell's treatment at Mill Film.

Kelly -- who quit animation work in 2017 to pursue a science degree -- said unpaid overtime is common. “In animation and (visual effects) we have major skilled labour shortages,” she said, adding that companies often don’t have the budget to hire more people. “We have to fill in those gaps with overtime and they don’t want to pay us for it.”

Kelly said she got involved with union organizing after working on a project as a storyboard artist. She said her workload suddenly doubled but her deadline remained the same. The work – which required hours of unpaid overtime – damaged her wrist and her eyesight, she said.

“My physical body was being harmed, my mental capacity was being harmed and my relationships were being harmed. And I looked around and I said, what is this for? A PBS show for children?”

For many workers in animation, the job is a part of their identity, Kelly said. “People don’t do this because they just want a job, they do this because they have a skill and a passion.

“They eat, live and breathe this.” But behind the scenes, she said, “there’s blood on the screen.”

Your favorite music can send your brain into a pleasure overload

Bringing neuroscience out of the laboratory and into the concert hall

FRONTIERS

Research News

We all know that moment when we're in the car, at a concert or even sitting on our sofa and one of our favorite songs is played. It's the one that has that really good chord in it, flooding your system with pleasurable emotions, joyful memories, making your hair stand on edge, and even sending a shiver or "chill" down your spine. About half of people get chills when listening to music. Neuroscientists based in France have now used EEG to link chills to multiple brain regions involved in activating reward and pleasure systems. The results are published in Frontiers in Neuroscience.

Thibault Chabin and colleagues at the Université de Bourgogne Franche-Comté in Besançon EEG-scanned the brains of 18 French participants who regularly experience chills when listening to their favorite musical pieces. In a questionnaire, they were asked to indicate when they experienced chills, and rate their degree of pleasure from them.

"Participants of our study were able to precisely indicate "chill-producing" moments in the songs, but most musical chills occurred in many parts of the extracts and not only in the predicted moments," says Chabin.

When the participants experienced a chill, Chabin saw specific electrical activity in the orbitofrontal cortex (a region involved in emotional processing), the supplementary motor area (a mid-brain region involved in movement control) and the right temporal lobe (a region on the right side of the brain involved in auditory processing and musical appreciation). These regions work together to process music, trigger the brain's reward systems, and release dopamine -- a "feel-good" hormone and neurotransmitter. Combined with the pleasurable anticipation of your favorite part of the song, this produces the tingly chill you experience -- a physiological response thought to indicate greater cortical connectivity.

"The fact that we can measure this phenomenon with EEG brings opportunities for study in other contexts, in scenarios that are more natural and within groups," Chabin comments. "This represents a good perspective for musical emotion research."

EEG is a non-invasive, highly accurate technique that scans for electrical currents caused by brain activity using sensors placed across the surface of the scalp. When experiencing musical chills, low frequency electrical signals called "theta activity" -- a type of activity associated with successful memory performance in the context of high rewards and musical appreciation -- either increase or decrease in the brain regions that are involved in musical processing.

"Contrary to heavy neuroimaging techniques such as PET scan or fMRI, classic EEG can be transported outside of the lab into naturalistic scenarios," says Chabin. "What is most intriguing is that music seems to have no biological benefit to us. However, the implication of dopamine and of the reward system in processing of musical pleasure suggests an ancestral function for music."

This ancestral function may lie in the period of time we spend in anticipation of the "chill-inducing" part of the music. As we wait, our brains are busy predicting the future and release dopamine. Evolutionarily speaking, being able to predict what will happen next is essential for survival.

Why should we continue to study chills?

"We want to measure how cerebral and physiological activities of multiple participants are coupled in natural, social musical settings," Chabin says. "Musical pleasure is a very interesting phenomenon that deserves to be investigated further, in order to understand why music is rewarding and unlock why music is essential in human lives."

How the study was done:

The study was carried out on 18 healthy participants - 11 female and 7 male. Participants were recruited through posters on the campus and university hospital. They had a mean age of 40 years, were sensitive to musical reward, and frequently experienced chills. They had a range of musical abilities.

A high-density EEG scan was conducted as participants listened to 15 minutes of 90 s excerpts of their most enjoyable musical pieces. While listening, participants were told to rate their subjectively felt pleasure and indicate when they felt "chills". In total, 305 chills were reported, each lasting, on average, 8.75 s. These findings implied increased brain activity in regions previously linked to musical pleasure in PET and fMRI studies.

Two centuries of Monarch butterflies show evolution of wing length

CREDIT: MICAH FREEDMAN, UC DAVIS

North America's beloved Monarch butterflies are known for their annual, multi-generation migrations in which individual insects can fly for thousands of miles. But Monarchs have also settled in some locations where their favorite food plants grow year round, so they no longer need to migrate.

Micah Freedman, a graduate student at the Center for Population Biology at UC Davis, took a deep dive into museum collections to see how migration has shaped the species. Monarchs are native to North America, but have also established non-migrating populations in the Caribbean, Central and South America, and islands in the Pacific and Atlantic oceans. These island-hopping butterflies may have been blown by storms before being lucky enough to reach dry land.

Monarchs that established new, non-migrating populations also had those larger wings. But over time, the wings of these colonists got smaller.

Selection at work in opposing directions

The shift between longer and shorter wings shows two opposite selection forces at work, Freedman and colleagues wrote in a paper published this week in Proceedings of the National Academy of Sciences. Migration selects for longer, larger forewings while non-migration seems to relax this and lead to smaller wings.

Alternatively, wing size could be influenced by other environmental factors depending on where butterflies are hatched and grow up. To test this, Freedman raised Monarch butterflies from non-migrating populations in Hawaii, Guam, Australia and Puerto Rico outdoors in Davis, California alongside native migrating Monarchs. The non-migrating butterflies retained their smaller wings, showing that the effect is due to genetics and not the rearing environment.

"Our findings provide a compelling example of how migration-associated traits may be favored during the early stages of range expansion, and also the rate of reductions in those same traits upon loss of migration," the authors wrote.

Researchers at Texas A&M University have come up with an economical, green solution that can help underprivileged communities with their water and electricity needs.

Their standalone water-energy nanogrid consists of a purification system that uses solar energy to decontaminate water. The setup, they said, is mathematically tuned to use solar energy optimally so that the water filtration is unhindered by the fluctuations of solar energy during the course of the day.

"To serve areas that are remote and isolated, the infrastructural cost of laying down new water pipes or setting up an electricity grid is enormous and can take a very long time," said Le Xie, professor in the Department of Electrical and Computer Engineering. "To overcome these hurdles, we presented a cost-effective solution that uses solar energy to both purify water and generate electricity for basic household use."

The researchers have described their technology in the journal Applied Energy.

In the United States, the colonias represent one of the many rural, low-income communities along the Texas-Mexico border where basic resources are not readily available. Since the colonias are remote, their residents, consisting of mainly migrant workers, are isolated from major utility and water treatment facilities and thus have limited means for electricity and safe drinking water. Methods like boiling water can be cost-prohibitive and inadequate.

"Boiling water is one of the most expensive ways of decontamination because it takes a lot of energy to heat water," said Shankar Chellam, professor in the Zachry Department of Civil and Environmental Engineering. "Also, although boiling gets rid of biological contaminants, it does not remove many chemical contaminants. We needed a solution that could address both these problems at the same time."

An efficient way to decontaminate water is by passing it through purification systems. These machines use pumps to push water through a filter. However, the pumps require electricity, which is again scarce in the colonias. So, the researchers looked for a solution that would help with both the power and water requirements of the colonia residents.

First, to cut the dependence on centralized sources of power and water, Xie, Chellam and their team conceptualized an energy-water nanogrid, which is a standalone, truck-mountable filtration system with pumps that could run on solar-generated electricity. Next, they developed a cost-minimization mathematical scheme, called scenario-based optimization framework, that minimized the total expenditure for the standalone setup by selecting the type of filter, the number and size of solar panels and the size of the solar battery.

This model revealed that if nanofiltration, a type of purification technique, was used, harvesting solar energy just during peak availability was sufficient to run pumps and purify water. In other words, the water nanofiltration system was largely unaffected by the day-to-day vagaries in solar energy and could purify enough water to meet the weekly water needs of the community. In this way, any excess solar power that was not used for filtration could be stashed away either for storage in the battery pack or for other minor basic household needs, like charging cell phone batteries.

The researchers noted that although the nanofiltration system is more sophisticated and expensive than other filtration methods, its overall merit is that it can successfully desalinate and remove chemicals, like arsenic, present in local groundwater. They said nanofiltration is a preferable method for desalination and water purification for other remote regions where the contaminants within the water are not already known.

"We have for the first time used a very rigorous mathematical approach to interlink water purification and energy provision," Chellam said. "This lays out a quantitative framework that can be used in not just the colonias but in any scenario based on local conditions."

Short-term moisture removal can eliminate downy mildew of spinach

Downy mildew is the biggest threat to spinach production around the world. While the pathogen has a short life cycle (approximately a week), it can produce millions of spores during the spinach growing season. Overhead sprinkler irrigation systems and dew formation on cool nights leads to more moisture, which enables these spores to infect the spinach.

Scientists at the University of Arkansas explored the relationship between available moisture and disease establishment and in a recent article they demonstrated that removing moisture decreased both spore survival and disease. Even a 30-minute dry period reduced spore germination to almost zero. Spores were unable to recover and cause disease on spinach.

In another experiment, they found that the micro-environment of a leaf surface can facilitate spore survival. They covered spinach plants with a spore solution and allowed the plants to dry out for different periods of time. They found that when the spores were on the plants, they were better at surviving in dry conditions but after enough time they found a reduction in disease. They also showed that standing water on leaves is essential for the spores to cause disease. These findings can be leveraged to design better disease management strategies for growers.

"We were also interested in understanding how new races of the downy mildew pathogen originate," explained Braham Dhillon, the first author of the paper. "The pathogen produces another type of long-lived spore known as an oospore, that can become dormant and survive harsh weather and remain viable in soil for long periods of time. But very little is known about the role of oospores in the life cycle of the spinach downy mildew pathogen."

Dhillon and colleagues were able to artificially produce oospores in the lab by mating two different strains of the downy mildew pathogen. This is a critical step in trying to determine the environmental factors that control oospore dormancy and germination.

"We demonstrated that oospores are produced abundantly in commercial spinach production areas in Arizona and California, the largest spinach growing area in the U.S.," said Dhillon. "This was the first direct evidence that different strains of the spinach downy mildew were present, can mate, and produce hybrid progeny in the field and potentially contribute to emergence of new pathogenic races of the pathogen."

Self-watering soil could transform farming

AUSTIN, Texas -- A new type of soil created by engineers at The University of Texas at Austin can pull water from the air and distribute it to plants, potentially expanding the map of farmable land around the globe to previously inhospitable places and reducing water use in agriculture at a time of growing droughts.

As published in ACS Materials Letters, the team's atmospheric water irrigation system uses super-moisture-absorbent gels to capture water from the air. When the soil is heated to a certain temperature, the gels release the water, making it available to plants. When the soil distributes water, some of it goes back into the air, increasing humidity and making it easier to continue the harvesting cycle.

"Enabling free-standing agriculture in areas where it's hard to build up irrigation and power systems is crucial to liberating crop farming from the complex water supply chain as resources become increasingly scarce," said Guihua Yu, associate professor of materials science in the Walker Department of Mechanical Engineering.

Each gram of soil can extract approximately 3-4 grams of water. Depending on the crops, approximately 0.1 to 1 kilogram of the soil can provide enough water to irrigate about a square meter of farmland.

The gels in the soil pull water out of the air during cooler, more humid periods at night. Solar heat during the day activates the water-containing gels to release their contents into soil.

The team ran experiments on the roof of the Cockrell School's Engineering Teaching Center building at UT Austin to test the soil. They found that the hydrogel soil was able to retain water better than sandy soils found in dry areas, and it needed far less water to grow plants.

During a four-week experiment, the team found that its soil retained approximately 40% of the water quantity it started with. In contrast, the sandy soil had only 20% of its water left after just one week.

In another experiment, the team planted radishes in both types of soil. The radishes in the hydrogel soil all survived a 14-day period without any irrigation beyond an initial round to make sure the plants took hold. Radishes in the sandy soil were irrigated several times during the first four days of the experiment. None of the radishes in the sandy soil survived more than two days after the initial irrigation period.

"Most soil is good enough to support the growth of plants," said Fei Zhao, a postdoctoral researcher in Yu's research group who led the study with Xingyi Zhou and Panpan Zhang. "It's the water that is the main limitation, so that is why we wanted to develop a soil that can harvest water from the ambient air."

The water-harvesting soil is the first big application of technology that Yu's group has been working on for more than two years. Last year, the team developed the capability to use gel-polymer hybrid materials that work like "super sponges," extracting large amounts of water from the ambient air, cleaning it and quickly releasing it using solar energy.

The researchers envision several other applications of the technology. It could potentially be used for cooling solar panels and data centers. It could expand access to drinking water, either through individual systems for households or larger systems for big groups such as workers or soldiers.
