Space, the financial frontier

By Henry Getley

CONSERVATIVE WOMAN



AS I watched the successful flight of Richard Branson’s passenger rocket ship on Sunday, memories came flooding back of how, as wide-eyed children, my pals and I would dream of blasting off into space.

I well remember the Soviets starting it all for us in 1957 by launching their bleep-bleeping satellite Sputnik 1 to the amazement of the world and us earthbound kids. We’d been brought up on Dan Dare and Journey into Space, and now comic strips and radio dramas were at last becoming reality.

We then became accustomed to USSR and USA experimental flights with various mice, dogs, chimpanzees and monkeys, some of which did not survive, poor things.

However, nothing could compare with the astonishing achievement of April 12, 1961, when the Soviet cosmonaut Yuri Gagarin became the first man in space.

The 27-year-old Russian test pilot made a single orbit of the Earth in his Vostok 1 capsule before parachuting out of it an hour and 48 minutes later at 23,000ft and landing safely near Saratov on the River Volga. It had been a risky ride, but Man was reaching for the stars! At the age of ten, my friends and I were agog.

In school, all talk was of Gagarin, and our enterprising teacher thought the flight would make an interesting project for our class. So, more in hope than expectation, he wrote to the Soviet authorities asking for some literature.

He struck gold. Soon after – to the envy of other pupils – we were deluged with scores of booklets, maps and charts in English detailing the whole mission in easy-to-understand terms. I remember the excitement as the teacher gave us the blue-covered dossiers.

As far as I know, it wasn’t propaganda (a word none of us kids knew anyhow), just straightforward information with lots of photographs, diagrams and illustrations. We spent weeks afterwards copying pictures of Gagarin’s spaceship, writing essays about his flight and pretending to be him.

The triumph of Vostok 1 was lift-off, of course, for the frantic space race between the Soviets and the United States. Just 23 days later, the rattled Americans sent astronaut Alan Shepard up in a rocket called Freedom 7 – and henceforth poured billions of dollars into beating their Red rivals.

By 1969, the Americans had overtaken the Soviets and launched Apollo 11 on a manned mission to the Moon. Eight years on from Gagarin, my enthusiasm for space adventure was as strong as ever and the prospect of a Moon landing was awesome.

I had a summer job at a local factory that year, which meant rising at 5am for the early shift. However, I stayed up late on July 20 to watch the grainy television coverage of the lunar landing. Like millions worldwide, I was elated when we finally heard Neil Armstrong’s crackly voice saying: ‘Houston. Tranquility Base here. The Eagle has landed.’

It was hard to sleep. And at 5.30am, as I left for work, the Moon was still visible in the dawn sky. I looked up at it and thought: ‘My God, men are actually on the Moon.’ It was a wondrous, almost unreal, feeling, cherished as a milestone memory.

Amid the euphoria over Armstrong’s giant leap for mankind, there were fantastic predictions that within a few short years, rocket flights would become accessible to all and we’d be taking weekend breaks on orbiting space stations, or holidaying on the Moon instead of jetting off to Benidorm. More lunar missions came and went, so much so that they became routine – apart from the drama of Apollo 13.

But the age of the semi-detached suburban spaceman was not to be. With its astronomical costs, space flight remained the preserve of the expert few, affordable only by governments and carried out in the name of science and exploration rather than recreation.

However, in the past decade we have seen the advent of ambitious business billionaires such as Branson, who reckon they can make out-of-this-world travel easier and cheaper, and take on paying passengers.

On Sunday, the Virgin entrepreneur and five others made a sub-orbital flight in his VSS Unity rocket – built by his Virgin Galactic company – reaching the edge of space at 55 miles high before returning safely to a New Mexico airstrip.

Branson has now taken a lead in the mini space race with Amazon tycoon Jeff Bezos, who builds rockets via his Blue Origin company. Next Tuesday, Bezos plans to launch his New Shepard craft – named in honour of the US astronaut – taking him and five fellow travellers some 62 miles above Earth.

Although these are not orbital flights, and there is even a technical dispute about whether Branson’s rocket actually reaches space, it’s exciting stuff. You get a mind-boggling view of our planet and experience weightlessness for several minutes.

Yet things come down to earth with a bump when it gets to the cost … you need pockets as deep as a Martian crater to afford a flight. Virgin Galactic has apparently already taken 600 bookings at a whopping £250,000 each.

New Shepard fares are so far unknown, but presumably will be similar. We’re not talking economy class here – in June, a single seat on Bezos’s rocket ship was auctioned off to an anonymous bidder for 28million dollars.

Meanwhile, Tesla billionaire Elon Musk’s SpaceX Corporation will be flying four passengers to the International Space Station next year at a cost of 55million dollars a head.

So, like one of those new-fangled reusable rockets, things have come full circle – and space flight for the financially-challenged masses is sadly as far away as ever. It’ll remain a rich man’s plaything.

No matter. We ageing latter-day Dan Dares may never be able to afford a cosmic journey. But, having followed the stardust trail of the heroic Gagarin, Armstrong and other pioneer rocketeers all those years ago, we can still gaze up at the heavens and let our dreams take flight.
Rising oil price may speed shift to electric vehicles, says energy watchdog

IEA analysis offers hope for climate action but says inflated oil price may slow global economic recovery from Covid-19

Rising oil prices could help speed climate action by accelerating the shift to electric vehicles, but would come at the expense of the economic recovery from the Covid-19 pandemic, according to the global energy watchdog.

The world’s demand for crude surged by an average of 3.2m barrels a day (b/d) in June compared with the previous month but the return of oil production has failed to keep pace, triggering a steady rise in market prices.

The International Energy Agency (IEA) warned that oil prices, which climbed by two-thirds this year to highs of $77 a barrel earlier this month, could climb higher and lead to market volatility unless big oil producers pump more barrels.

“While prices at these levels could increase the pace of electrification of the transport sector and help accelerate energy transitions, they could also put a drag on the economic recovery, particularly in emerging and developing countries,” the IEA said

US drivers are already facing record high prices to fill up their tanks due to rising oil market prices. The price per gallon reached an all-time high of $3.14 on Monday, and analysts have warned that the price could climb to $5 a gallon.

As a result, the cheaper price of running an electric vehicle may encourage more motorists to make the switch sooner than planned, boosting efforts to cut emissions from transport. But higher fuel prices could also stoke cost inflation across the global economy, particularly in developing countries.

The Paris-based agency used its influential monthly oil market report to warn members of Opec and its allies (Opec+) that without success in its oil production talks the market would “tighten significantly as demand rebounds from last year’s Covid-induced plunge”.

Oil demand fell at its steepest rate since the second world war after the outbreak of coronavirus, from 100m barrels of oil a day to just over 91m barrels. But demand could rebound at its quickest rate on record to reach pre-pandemic levels by the end of 2022, according to an earlier IEA report.

The Opec+ talks to determine how quickly to increase the cartel’s oil production after historic production cuts last year fell apart last week, meaning output from the cartel is expected to rise by only 400,000 b/d from August.

Meanwhile, the IEA has predicted that between July and September oil demand could rise to 3.3m b/d higher than the previous quarter.

In Europe, demand for air transport grew “significantly” in June, boosting demand for transport fuels. The number of scheduled seats increased by 52% in the UK compared with May, according to data provider OGA, with similar increases recorded for France (46%), Germany (44%) and Spain (53%).

The mismatch between fast-rising oil demand and a slower pace of oil production could lead to oil market volatility if there is uncertainty over the future oil supply from Opec+. Ultimately, volatility in the market “does not help ensure orderly and secure energy transitions – nor is it in the interest of either producers or consumers”, the IEA said.
SO MUCH FOR THE ALBERTA ADVANTAGE

Canadians don’t want to move to Alberta

Brain drain continues for Alberta


CALGARY -- Last year yoga instructor Jess Leblanc packed up left Alberta, and moved to Vancouver Island.

The COVID-19 pandemic slammed her business, and in the downtime that followed she realized Alberta wasn’t providing the lifestyle she wanted.

"Politically I didn't necessarily fully think that the values that were being prioritized were reflective of my own or in alignment with mine," Leblanc said, in an interview with CTV News. "Plus, I was in a situation where I was unemployed, gyms, yoga facilities, the schools, where I do a lot of work in education (were closed) as well.

Could Alberta be showing the first signs of 'brain-drain'?

"So there wasn't a lot of wiggle room for me to be maximizing my career at the time," said Leblanc. “So many people that I know have opted to make the switch, and change and move. I just think that with COVID-19 for me anyway, and for I think for a lot of people in my circles, it has highlighted a sense of urgency to live your life the way that you really want to live your life.”

MORE PEOPLE LEAVING

StatsCan data shows Leblanc had a lot of company in her move out of Alberta: June 2021 marked the fourth consecutive quarter of net negative inter-provincial migration.

3,384 more people moved out of Alberta heading to other provinces than arrived here from them.

B.C. was the big winner in the migration sweepstakes, with over 9,000 more Canadians moving there to live.

The biggest factor, said ATB Deputy Chief Economist Robert Roach, is employment.

“A big driver, especially in Alberta is economic conditions: are people going to find a job?" said Roach. "They come here looking for jobs, and if they can't find one, or the opposite happens, and unemployment starts to rise, they tend to leave. So that's exactly what's happened.”

Alberta's job numbers declined in June according to Statistics Canada's latest labour market survey.

That survey showed the province lost a total of 37,000 full-time jobs in June. Almost all were replaced by part-time employment which increased by 36,800. It boosted Alberta’s unemployment to 9.3 per cent,

WOMEN AND YOUTH HARDEST-HIT

Women and youth are the hardest hit said Dexter Lam, manager of talents, research and strategy at Calgary Economic Development. “There are changes where employment for childbearing-age women, and especially part-time positions for childbearing-age women are not where they were before and haven't been," said Lam. "And it's a matter of time, of whether we'll actually even see those come back, unless something drastic is done.”

"Youth have similarly been hit," he added. "We're seeing where unemployment in youth or really, sort of a lack of employment for youth means its not quite where it was before.”

Lam said the return of employment has not played out equally for the sexes with men seeing the biggest boost in jobs. “So for men, there's more men employed than there were pre-pandemic. So you know, when we look at the overall numbers, we're close to where we were, where you can say, we're pretty much where we would be before the pandemic started.”

UCP POLICIES TO BLAME: NOTLEY

Alberta NDP leader Rachel Notley said the policies of Alberta's UCP government are to blame for low interprovincial migration numbers, saying it is failing to make the province a desirable destination.



“Young professionals are looking for an economy that is diversifying and, and providing opportunities in the tech sector and renewable sector and, all these sort of growing areas, as opposed to ours, where the government seems committed to recreating the jobs of 30 years ago," said Notley. “They need to change course, they need to support women in the economy, something that they're steadfastly and stubbornly refusing to do right now.

"Those things are the opposite of the messages that we're getting from the Jason Kenney government right now," Notley added, "and as a result, people are starting to drift away. “

COMPANIES MOVING TO ALBERTA


Alberta’s minster of Labour and Immigration Jason Copping paints a rosier picture of the province. In a written statement to CTV delivered through his press secretary Copping said, “While we recognize that inter-provincial migration is occurring, we continue to attract job-creating professionals from across the country and around the world.

"For example," he said, continuing. "Five companies – including mCloud, Infosys, Mphasis, Air Products and Bird – have announced their intentions to move their headquarters to Alberta to create as many as of 6,250 jobs.



"As our economy recovers and continues to grow, Alberta’s government will continue to support actions that get Albertans back to work.”

Copping also said long-term projections are for Alberta’s population to continue to increase in the years and decades to come.

"It is important to remember that long term projections show that Alberta’s population will continue to grow in the years and decades to come," he said.

ALBERTA STILL GROWING

And in fact, while interprovincial migration is in negative territory people from outside Canada are still choosing to move to Alberta. StatsCan data shows Alberta posted a net gain of 24,911 people from international locations in 2020. While still in positive territory, that was a drop pf 49 percent from 48,805 net international migrants in 2019.



Jess Leblanc told CTV News she is moving from Calgary to Vancouver Island to have a lifestyle that better aligns with her values. According to StatsCan, inter-provincial migration out of Alberta continued in June.

 

A history of drug dependence is associated with negative mental health outcomes

Achieving excellent mental health after drug dependence is more prevalent among older respondents, those with a post-secondary education, married respondents, those with higher levels of social support, and those without a history depression or anxiety

UNIVERSITY OF TORONTO

Research News

New research published online in the International Journal of Mental Health and Addiction found that Canadians with a history of drug dependence are much less likely to have flourishing mental health and are more likely to have mental illness.

Researchers compared a nationally representative sample of 460 Canadians with a history of illicit drug dependence (excluding cannabis) to 20,305 Canadians with no history of illicit drug dependence using data drawn from Statistic Canada's Canadian Community Health Survey-Mental Health.

While 80% of those with a history of drug dependence were in remission, more than half (52.1%) were still experiencing mental illness. Further, only 37.9% were in excellent mental health, which is markedly lower than the 74.1% of Canadians without a history of drug dependence who had excellent mental health. To be considered in excellent mental health, participants had to report: 1) freedom from mental illness in the previous year (i.e., substance dependence, psychiatric disorders, suicidality); 2) almost daily happiness or life satisfaction in the past month; and 3) high levels of social and psychological well-being in the past month.

"Remission from dependence is an important factor in the recovery process, but we also want to consider mental health outcomes beyond abstinence," says first author, Andie MacNeil, a recent Master of Social Work graduate from the University of Toronto. "We want to think about how we can support the psychological and social well-being of people recovering from drug dependence."

The current study found several factors that were associated with excellent mental health among those in remission from drug dependence, including older age and social support.

"As people age, they often experience declines in impulsivity and increased role responsibilities in their personal and professional lives," says senior author Esme Fuller-Thomson, professor at the University of Toronto's Factor-Inwentash Faculty of Social Work and director of the Institute for Life Course and Aging. "Older individuals often move away from the social circles and contexts where drug use is more prevalent, which in turn can help support their recovery."

A post-secondary education, being married, and no lifetime history of major depressive disorder or generalized anxiety disorder were among the other factors associated with both remission from drug dependence and excellent mental health.

Although the Statistics Canada survey used for the study did not collect information on interventions that participants may have used to support their recovery, other research indicates that various psychosocial approaches (such as Motivational Interviewing, Cognitive Behavioral Therapy) and pharmacological approaches (such as Opioid Agonist Therapy) can help individuals reduce drug use and recover from dependence.

Drug dependence is a major public health crisis, with drug overdoses now representing one of the leading causes of death for adults under 50 in the United States. Although opioids tend to be the driving substance behind overdose deaths, there has been significant increases in cocaine-involved deaths and psychostimulant-involved deaths in recent years. In the United States, illicit drug use has an estimated cost of $193 billion per year due to healthcare expenditures, criminal justice costs, and loss productivity.

"Considering the tremendous loss of life due to drug dependence and its associated economic consequences, there needs to be a greater understanding of factors associated with both remission and with broader aspects of recovery, such as mental well-being," says MacNeil.

Methamphetamine use drove surge in heart failure hospitalizations, costs in California

Circulation: Cardiovascular Quality and Outcomes journal report

AMERICAN HEART ASSOCIATION

Research News

DALLAS, July 14, 2021 -- Heart failure hospitalizations and costs related to methamphetamine use jumped sharply over a decade in California, according to new research published today in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.

"Our study results should bring urgent attention to this insidious yet rapidly growing form of severe heart failure - methamphetamine-related heart failure, which is taking the lives of young people, straining health care resources and threatening to spread like wildfire in California, the West and to the rest of the nation," said lead author Susan X. Zhao, M.D., a cardiologist at Santa Clara Valley Medical Center in San Jose, California. "California is seeing a resurgence of methamphetamine use, and the problem has been made drastically worse in recent years by the increase in purer, more potent methamphetamine throughout our communities."

Heart failure is a chronic condition in which the heart becomes too weak to properly pump blood. Signs of heart failure include fatigue, shortness of breath and heart palpitations. According to the American Heart Association's Heart Disease and Stroke Statistics--2021 Update, an estimated 6 million American adults ages 20 and older have heart failure based on 2015-2018 data. The condition is most prevalent among people ages 60 and older.

Methamphetamine, also known as meth, is an addictive stimulant that can affect the cardiovascular system by triggering blood vessel spasms and life-threatening spikes in blood pressure. It can also increase plaque in the arteries and rewire the heart's electrical system. Prolonged methamphetamine use has been associated with a severe form of dilated cardiomyopathy, a condition in which the weakened heart muscle becomes enlarged and cannot pump adequate blood. According to the 2017 U.S. National Survey on Drug Use and Health, 1.6 million people reported using methamphetamines, and the average age of new methamphetamines users was 23.

This study is a retrospective review of California hospital data including more than one million patients discharged between 2008 and 2018 with a diagnosis of heart failure. During that 11-year period, researchers noted:

  • 42,565 (4%) of the patients had been diagnosed with methamphetamine-related heart failure - also known as MethHF - compared with 990,511 (96%) diagnosed with heart failure unrelated to methamphetamine use.
  • Hospitalizations for methamphetamine-related heart failure rose 585%, while heart failure hospitalizations unrelated to methamphetamine use declined 6%.
  • 94% of methamphetamine-related heart failure patients were under age 65, with more than half being between ages 35 and 54.
  • 79% of methamphetamine-related heart failure patients were men, and nearly half of methamphetamine-related heart failure patients were white adults.
  • Methamphetamine-related heart failure patients were also more likely to consume alcohol and use tobacco and other illicit drugs. They were more likely to be homeless compared with other heart failure patients, as well.
  • People with methamphetamine-related heart failure had fewer pre-existing cardiovascular conditions such as atrial fibrillation or Type 2 diabetes, though, more had high blood pressure (33%) compared to heart failure patients who did not use methamphetamines (30%).

Researchers found that the financial toll of methamphetamine-related heart failure is also significant: hospital stays were several days longer than those of other heart failure patients, and they had more procedures performed, leading to significantly higher health care costs. Hospitalization costs for methamphetamine-related heart failure in California rose 840%, from $41.5 million in 2008 to $390.2 million in 2018, compared with an 82% increase in costs for all heart failure-related hospitalizations, which rose from $3.5 billion to $6.3 billion.

"Treating patients with methamphetamine-related heart failure is consuming resources and burdening the health care system," Zhao said. "Many patients present late in the course of illness with limited options available to them. Proactive, preventative public health outreach and education are needed to stem the influx of methamphetamine-related heart failure at its source."

Zhao said while methamphetamine-related heart failure may be seen as a "working class white men's disease", the demographics are shifting and diversifying, among people from different racial and ethnic groups and women, too. Methamphetamine-related heart failure is also spreading from urban areas to rural communities.

"The methamphetamine epidemic is often overshadowed by the surge in opioid-related death and illnesses," she said. "The long-term health consequences associated with methamphetamine use require recognition from the public as well as the clinical communities. This study was intended more as a public health alarm: the urgency of methamphetamine use disorder cannot be overstated."

An accompanying editorial by Uri Elkayam, M.D., and Pavan Reddy, M.D., commented that the inattention to methamphetamine-related heart failure may be due in part to a lower risk of immediate death caused by methamphetamine overdose as compared to opioids. However, they note methamphetamines are "equally dangerous and costly to society but more insidious in nature, its effects potentially causing decades of mental and physical debilitation before ending in premature death."

According to the editorial, "The rising prevalence of MethHF should ring alarm bells but also signals an opportunity. "Until recently, MethHF was highlighted only in the form of isolated case reports but is now seen regularly in high usage areas. Though this study makes strides in underscoring the potential societal impact of this protracted illness, prospective data from larger cohorts may help clarify questions left unanswered by the current study. Importantly, we do not know which risk factors predispose to the development of MethHF, which prognostic factors may predict cardiac recovery or which medical therapies may benefit patients. Additional understanding may simultaneously benefit the patient and alleviate spiraling healthcare costs."

Zhao and colleagues plan to work with public health agencies to develop a statewide awareness campaign in California and to examine national data to determine if it reflects what's happening at the state level, she added.

This study is limited in that it is a retrospective review of hospital discharge data based on a standardized coding system that may be susceptible to biases and confounding factors, including that certain groups of patients may be asked about drug habits more than other groups.

Study finds "thriving gap" between students who attend high school remotely vs. in person

Data from the pandemic show high school students studying remotely suffered socially, emotionally, and academically

AMERICAN EDUCATIONAL RESEARCH ASSOCIATION

Research News

Washington/Philadelphia, July 14, 2021--New research finds that high school students who attended school remotely during the COVID-19 pandemic suffered socially, emotionally, and academically compared with those who attended in person.

The study was published today in Educational Researcher (ER) by researchers Angela L. Duckworth, Tim Kautz, Amy Defnet, Emma Satlof-Bedrick, Sean Talamas, Benjamin Lira, and Laurence Steinberg. ER is a peer-reviewed journal of the American Educational Research Association.

"Many news stories have reported on individual stories of teenagers who have suffered from anxiety, depression, and other mental health challenges during the pandemic," said lead author Duckworth, a professor at the University of Pennsylvania and the founder and CEO of Character Lab. "This study gives some of the first empirical evidence of how learning remotely has affected adolescent well-being."

The study found a social, emotional, and academic "thriving gap" between students who had been attending school in person and their counterparts who had been attending remotely. The greater suffering of students attending school remotely held up when controlling for how students were faring on the same dimensions prior to the pandemic. Though not enormous in magnitude, the thriving gap was consistent across gender, race/ethnicity, and socioeconomic status--and even small effects are noteworthy when they impact millions of individuals.

On a 100-point scale, in-person students were rated higher than remote students on levels of social well-being (77.2 versus 74.8), emotional well-being (57.4 versus 55.7), and academic well-being (78.4 versus 77.3).

"Notably, the thriving gap was larger among students in 10th through 12th grades than it was among ninth graders," said Steinberg, a professor at Temple University.

"As policymakers gear up for national tutoring and remediation programs--which we agree are urgent priorities--we must recognize that our nation's students are not just lagging as performers, they are suffering as people," Duckworth said. "Meeting their intrinsic psychological needs--for social connection, for positive emotion, and authentic intellectual engagement--is a challenge that cannot wait."

As part of an ongoing research partnership with Orange County Public Schools, a large and demographically diverse public school district in Florida, the study authors had already administered the Character Lab Student Thriving Index--a confidential survey assessing students' current social, emotional, and academic experience--to over 6,500 students in February of 2020, just before the pandemic shut down schools.

Several months later, families in this district were offered the option of remote versus in-person classes for the 2020-21 school year. Two thirds of the students in the sample ended up attending school remotely, and one third attended school in person. Regardless of whether they were learning from home or attending classes at school, the same students completed the Student Thriving Index again in October 2020.

To capture social well-being, the survey included questions about fitting in at school, whether there was an adult in their school to whom they could turn for support or advice, and whether in their school there was an adult who always wanted them to do their best. For emotional well-being, teens responded on how often they were feeling happy, relaxed, and sad, as well as how they were feeling overall about their life. And for academic well-being, the survey asked how interesting teens found their classes, how important they found it to do well in their classes, and how confident they were that they could succeed in their classes if they tried.

Unlike other global crises, COVID-19 pandemic did not spark more smoking in its initial stage

UNIVERSITY OF WATERLOO

Research News

Unlike other population-level stressful events such as natural disasters, COVID-19 has not resulted in a net increase in smoking, according to a new study from the International Tobacco Control (ITC) Project, at the University of Waterloo.

The researchers also found that although nearly half of smokers reported that COVID-19 made them think about quitting, the vast majority of smokers did not change their smoking habits during the early phase of the COVID-19 pandemic.

Led by Shannon Gravely, research assistant professor with the ITC Project, the study surveyed 6,870 smokers and vapers in four high-income countries--Australia, Canada, England, and the United States--during the first global wave of COVID-19 between April and June 2020. The team examined the association between COVID-19 and thoughts about quitting smoking, changes in smoking, and factors related to positive changes such as attempting to quit or reducing smoking.

Only 1.1 per cent of smokers in the four countries attempted to quit and 14.2 per cent reduced smoking, but this was offset by the 14.6 per cent who increased smoking, with 70.2 per cent reported no change.

"It is important to note that population-level stressful events, such as 9/11 and natural disasters, have often led to increased smoking," said Geoffrey Fong, professor of psychology at Waterloo and principal investigator of the ITC Project. "So, our findings that there was no net increase in smoking in response to COVID-19 may actually represent a positive result for public health."

The study found that those who thought about quitting smoking because of COVID-19 were predominantly females, ethnic minorities, those with financial stress, current vapers, less dependent smokers, those with greater concern about personal susceptibility of infection, and those who believe COVID-19 is more severe for smokers.

According to Fong, who was a co-author of the study, this latter finding may be the key to why the COVID-19 pandemic has not led to significant increases in smoking, compared to past tragedies.

"Unlike other population stressors such as earthquakes, which are unrelated to smoking, COVID-19 severity is indeed linked to smoking," Fong said. "Public health officials have mentioned the link as yet another reason for smokers to quit, and over 80 per cent of smokers across the four countries believed that smoking made COVID-19 more severe. And this led to the lack of an increase in smoking, unlike what we have seen after other tragedies."

###

The study, Smokers' cognitive and behavioural reactions during the early phase of the COVID-19 pandemic: Findings from the 2020 ITC Four Country Smoking and Vaping Survey, was recently published in the journal PLOS ONE. The authors were Gravely, Fong, Lorraine V. Craig, K. Michael Cummings, Janine Ouimet, Ruth Loewen, Nadia Martin, Janet Chung-Hall, Pete Driezen, Sara C. Hitchman, Ann McNeill, Andrew Hyland, Anne C. K. Quah, Richard J. O'Connor, Ron Borland, Mary E. Thompson, and Christian Boudreau.

The study was funded by Health Canada's Substance Use and Addictions Program.

  • For the first time, scientists have seen stony coral cells engulf dinoflagellates - single-celled, photosynthetic algae that are crucial for keeping coral alive
  • The researchers used a cell line called IVB5, which contains endoderm-like cells cultured from the stony coral, Acropora tenuis
  • Around 40% of coral cells incorporated the algae in around 30 minutes and remained healthy for one month
  • The research is a step towards understanding the partnership between coral and dinoflagellates and could shed light on how coral bleaching occurs

In a world-first, scientists in Japan have observed individual stony coral cells engulfing single-celled, photosynthetic algae.

The microscopic algae, known as dinoflagellates, were engulfed by cells cultured from the stony coral, Acropora tenuis, the scientists reported in the journal Frontiers in Marine Science.

"Dinoflagellates are crucial for keeping coral healthy and alive," said Professor Noriyuki Satoh, senior author of the study and head of the Marine Genomics Unit at the Okinawa Institute of Science and Technology Graduate University. "Coral cells take up the algae and provide them with shelter and the building blocks for photosynthesis. In return, the algae provide the corals with nutrients that they synthesize."

However, in recent decades, this essential relationship has been placed under strain. Driven by pollution, acidification and rising ocean temperatures, stressed coral cells are expelling the microscopic and colorful algae in mass bleaching events, resulting in huge swathes of dead, white reefs.

Stony coral from the Acroporidae family - the most common type of coral found within tropical and subtropical reefs - are particularly susceptible to these bleaching events. These fast-growing corals lay down calcium carbonate skeletons and therefore play a key role in building coral reefs.

"For coral reef conservation, it's vital for us to fully understand the partnership between stony coral and the algae that live inside these animals, at the level of a single cell," explained co-first Professor Kaz Kawamura from Kochi University. "But until recently, this was very hard to achieve."

Coral cells are notoriously difficult to culture, so previously scientists had to rely on experimental systems of other closely related marine creatures, like sea anemones, to study the mechanism of how the dinoflagellates enter and leave cells.

It wasn't until April 2021 that the research team made a major leap forward, reporting in Marine Biotechnology that they had successfully cultured different cell lines from larvae of the stony coral, Acropora tenuis, in petri dishes.

For this study, the scientists focused on one coral cell line called IVB5. Many of the cells in this line have similar properties to endodermal cells, in terms of their form, behavior and gene activity. Importantly, in whole coral organisms, it is the endodermal cells that engulf the algae.

The scientists added the dinoflagellate, Breviolum minutum, to a petri dish containing the IVB5 coral cells.

Around 40% of the coral cells in the culture quickly formed long, finger-like projections that reached out to contact the dinoflagellates. The algae were then "swallowed" up, in a process taking around 30 minutes.

"It was amazing to see - it was almost a dream!" said Prof. Satoh.

Over the following couple of days, the algae inside the cell were either broken down into fragments or were successfully enclosed into membrane-bound sacs, called vacuoles, within the cells. For the researchers, this hints at how the relationship possibly started millennia ago.

"It may be that originally, the ancestors of coral engulfed these algae and broke them down for food. But then over time, they evolved to use the algae for photosynthesis instead," co-first author, Dr. Satoko Sekida from Kochi University suggested.

The researchers are now using electron microscopes to gain more detailed images of how the coral cells engulf the dinoflagellates. They are also working on genetic experiments to pinpoint which coral genes are involved.

At this stage, the coral cells containing the algae live for around a month before dying. In the near future, the team hope to achieve a stable culture where both the coral cells and dinoflagellates can reproduce together.

"This would be very exciting as then we can ask new questions, like how the corals react when placed under stress," said Prof. Satoh. "This could give us a more complete understanding of how bleaching occurs, and how we can mitigate it."

How does the world use emojis?

New study finds universals expressions across countries and continents

👹👺😄😢


UNIVERSITY OF SOUTHERN CALIFORNIA

Research News

Before Millennials were over laugh-cry emojis, they were the most used emojis across the world, according to researchers at USC. The emoji was more popular than smiley faces say researchers who categorized millions of tweets across 30 countries and evaluated over 1700 emojis. Their study, "An empirical study of emoji usage on Twitter in linguistic and national contexts" was published in Online Social Networks and Media.

Mayank Kejriwal, a research assistant professor in the Department of Industrial and Systems Engineering, and a research lead at the USC Information Sciences Institute who is the lead author on the paper, says approximately 100 emojis are used most often.

The most important take away? Emojis represent the human condition and that we are more alike than different. Universal emotions dominated, says Kejriwal. Less popular are the tribalism and differences demonstrated by showing flags.

While the term emoji comes from Japanese language, greatest use of emojis on Twitter came from the English-speaking world, Spanish speaking nations and Arabic speakers.

The countries most likely to use emojis outside the US? The Philippines, Brazil and India. Most prominent emoji out of the Middle East? Representations of love--the heart.

Across the world, coastal cities tend to use emojis more than inland areas.

Contextually, in Brazil, tweets about family were mostly likely accompanied by hearts, in the US, there were few tweets about family that were accompanied by emojis.

Nuclear-powered spacecrafts? NASA taps Blue Origin, GE to try it

NASA and the US Department of Energy awarded three $5m contracts to produce reactor-design concepts that could be used to ferry people and cargo to Mars someday.

Nuclear energy has lost favor in much of the world, but the sky’s the limit when it comes to outer space.

The U.S. government is drawing on the expertise of Jeff Bezos’s Blue Origin space venture, General Electric Hitachi Nuclear Energy and other companies to develop nuclear-powered spacecraft that can travel faster and farther — to Mars and beyond.

NASA and the Energy Department awarded three $5 million contracts to produce reactor-design concepts that could be used to ferry people and cargo to Mars or propel scientific missions to the outer reaches of the solar system, the space agency said in a statement Tuesday.

Defense contractors Lockheed Martin Corp. and Aerojet Rocketdyne Holdings Inc., as well as drone maker General Atomics and BWX Technologies Inc., which makes nuclear components and fuel, are among the companies involved in the effort.

“These design contracts are an important step towards tangible reactor hardware that could one day propel new missions and exciting discoveries,” Jim Reuter, associate administrator for NASA’s Space Technology Mission Directorate, said in the statement.

Nuclear propulsion systems are more efficient than standard chemical-based rockets, meaning they hold promise for traveling faster for more ambitious missions, deeper into space, according to the National Aeronautics and Space Administration.

Meanwhile, nuclear energy now produces about 10% of the world’s electricity, down from a peak of 18% in the mid-1990s.

It could take several years to develop the technology for space travel, which faces significant hurdles. While nuclear power plants have been used for decades in submarines and aircraft carriers, placing one on an explosive rocket poses significant risks.

The nuclear space effort comes amid a resurgence in extra-planetary activity, with the U.S. government exploring Mars and planning the first manned mission to the moon in decades.

Meanwhile, companies backed by celebrity billionaires are racing to commercialize space tourism.

Virgin Galactic Holdings Inc. on Sunday completed a suborbital test flight with founder Richard Branson aboard.

Amazon.com Inc. founder Bezos plans to fly to space next week on a rocket made by Blue Origin.

General Electric Co. made many of the 1970s- and 1980s-era reactors that derive energy from boiling water and that remain at the heart of the U.S. nuclear portfolio.

More recently, the company has specialized in smaller reactors that don’t need the same infrastructure, through its joint venture with Hitachi Ltd. Development and interest in bigger nuclear power has slowed in recent years due to cost overruns and backlash following the Fukushima, Japan, meltdown in 2011.
