Canada’s first chess prodigy and grandmaster still commands international respect

Fans of The Queen’s Gambit know that chess prodigies are possible, but many may not realize that Canada had its very own prodigy nearly a century ago.

Abe Yanofsky of Winnipeg started winning national events at 11, and 80 years ago he won the first of his eight Canadian championship titles.

It was hardly a surprise, because he had already notched some significant international successes. He represented Canada at the Buenos Aires Olympiad when he was 14, winning the prize for best performance on the second board.

Even the reigning world champion took note of the young Canadian’s play, especially his game against the Peruvian champion which is featured in today’s diagram. The game was included in a compilation of chess highlights of the 20th century.

Yanofsky went on to become the first Grandmaster in Canadian history, and arguably the strongest player Canada has ever produced. While studying in London, he also managed to become British champion.

But chess wasn’t Yanofsky’s only pursuit. He was a practising lawyer, and an elected official. He became mayor of the Winnipeg suburb of West Kildonan, and served for many years on Winnipeg city council.

He died in 2000 at the age of 74.

Answer:

White uncorked 22.Rxe6+ and after Kxe6 23.Re1+ Kd6 24.Qf6+ Kc5 25.Re5+ Kc4 and White can force mate.

Check mates: how chess saved my mental wellbeing

Sam Parker’s grandfather taught him to love chess, a joy he rediscovered in the pandemic, along with a deeper understanding of its positive effects on mental and emotional health

My grandfather was a man with a tut as loud as a dropped plate. He’d deploy it whenever you fell short in some way: a length of the pool finished too slowly; a garden bed not weeded well enough; a portion of vegetables left unfinished. But he softened over chess, a game he bequeathed to me over long sessions, played in our pyjamas by the fireplace. Across the board, his sternness would melt into a kind of pensive calm, the admonishments replaced with instructions and then a small smile when he saw the move that would win the game and send me to bed.

He played chess all his life and was chairman of his local club right up until he entered the retirement home where he died, but I didn’t follow his example myself until some 25 years later. By then it was too late to thank him.

The moment came at around 6pm on New Year’s Day 2021. Lying alone on my living room carpet, watching the first rain drops of the year drizzle on to the window, all the adrenaline of the past 12 months seemed to evaporate, leaving behind an overwhelming sense of dread. Like everyone else, I’d made it to the end of 2020 only to find Covid wasn’t going anywhere, and now the thought of resuming what passed for “real life” towered over me like the biggest pile of dirty dishes – which, incidentally, was also waiting in the kitchen.

Desperate for a distraction, I opened my laptop and logged into chess.com for the first time in years. With a heavy, hopeless sigh, I made the move drilled into me as my tiny primary school’s fourth best player, who was roundly beaten in the junior club semi-finals by Jason Wood in front of my father in 1992 – king’s pawn to E4.

I was not alone. People all around the world were discovering chess. In the year after March 2020, chess.com picked up over 11 million new users, many no doubt inspired by Netflix’s The Queen’s Gambit. On live streaming apps, such as Twitch, blossoming communities of young chess players were revelling in the strange, shared language with which you can analyse and debate games. At a time of existential worry, something about a 1,500-year-old boardgame was drawing people in.

One silver lining of Covid was the rapid development in our conversation about mental health. In Britain, this was something at least partially ignited by the sobering National Office of Statistics report in 2014 which named suicide, for the first time, as the number one killer of men under 50. The conversation kept simmering in subsequent years, with moments such as #MeToo, which made us reconsider the way victims process trauma, and then Donald Trump, a real-time experiment in untreated narcissism during which the game “would you go back in a time machine and kill baby Hitler” became replaced by “would you go back in a time machine and give baby Trump a hug”.

But the pandemic was the moment for many of us when mental health went from the political to the abruptly personal. Family c onversations about my (other) grandfather – alive at the time, but on his own when lockdown started – changed quickly from keeping him physically well to how we could prevent him becoming depressed. Managers and HR departments, fearful of losing unseen staff to long-term stress, quickly learned the language of self-care. (“We just had an online seminar,” a newly evangelical 60-year-old neighbour and veteran of corporate finance told me, “called ‘It’s OK to not be OK.’”)

Most of all, we had to learn coping mechanisms for ourselves. No matter where you sat on the “quite lucky, really!” continuum, Covid was a mental health challenge. For me, this meant increased bouts of acute anxiety, something I’ve experienced since childhood; an all-consuming dread, often coupled with extreme self-criticism, which makes it difficult to eat properly, sleep or feel optimism or joy.

Searching for the right ways to cope had led to a skipping-in-the-garden phase, an ill-fated morning meditation regime, the month I became briefly but intensely obsessed with the teachings of Wim “the Iceman” Hof and started each day with loud breathing exercises and a cold shower (admittedly with more commitment to the former than the latter). Next came journaling – churning out pages and pages of stream-of-consciousness misery in an effort to purge my way to feeling better.

Where I didn’t expect to find relief was in an ancient board game, which had previously left me so humbled and humiliated I’d retreat in frustration after a few days and swear off it for good. But this time something clicked. By the end of January, I was playing several games a week; 10 months later, I play at least three or four times a day.

Chess, I quickly realised, was giving me far more than just a pleasant distraction. Instead, it was offering a window of clarity into my state of mind, a place where the fog of the day’s stresses and distractions were cleared to show me what was really going on, good or bad. My therapist had often told me: you need to find ways to tune into more of your emotions, not just anxiety but the rest of the “big four”; joy, sadness, and anger. Chess is an extremely fast route to experiencing them all – often within the course of a few moves. At a time when the outside world was too extreme to contemplate, it became a useful internal bellwether. If I was playing with frustration and impatience, I knew tackling that big problem at work or having that difficult conversation with a friend or partner was probably best left until tomorrow. If I was playing with grit and purpose, it clarified that I was strong and gave me the confidence to do what needed to be done elsewhere.

In chess, there is no element of chance: no dice to throw, no bit of kit that can falter (unless the board splits in two, which is fairly unlikely), no adverse weather conditions to point to and curse. It is a pure test of your ability to master your thoughts and emotions in the moment; failure to make a good move is, ultimately, the only thing that leads to your downfall. This is why you punch the air when you win and feel unspeakably furious with yourself when you lose. In chess, there are no ways to downplay your victory or excuse your defeat.

Then there is the obvious matter of resilience. Chess is a relentless, real-time test of your resolve. Can you make a mistake (called “blunders” in the game) – particularly the worst ones, like losing a queen – and keep going, or do you slam your laptop shut and be grumpy for the rest of the evening? Do you react to a setback by lashing out with an ill-considered attack, or can you take a breath, analyse the situation and make a smart move instead? Can you contain the joy of winning a clear advantage, and not get complacent? (Comebacks in chess are almost always about this.) Chess, in short, began to feel like a mindfulness exercise and an emotional HIIT class rolled into one. What was hard to tell was whether it was truly transformative, or whether I was merely projecting what I needed on to chess at that time, just as others were with birdwatching or baking.

The traditional view of chess is that playing it will make us smarter, that its unique blend of arithmetic, geometry and lateral thinking offers a workout for the mind that will make us stronger at logic, strategy and problem-solving. Just as heavyweight boxers are used as shorthand for physical supremacy, chess players are considered the height of intelligence, if not genius. This is certainly the view in places such as Armenia, the only country in the world to make chess mandatory in school (resulting, unsurprisingly, in one of the world’s highest proportions of grandmasters).

The problem is, this is a romantic fallacy with no scientific basis. At least that’s the conclusion of Fernand Gobet, author of The Psychology of Chess and an international master who once faced the great Garry Kasparov when part of the Swiss national team. A cognitive scientist and professor at Liverpool University, he has researched the question of chess’s relationship to intelligence.

“About 15 years ago,” Gobet says, “someone from the US Chess Fan Federation asked me to research the benefits of chess on education. He told me: ‘I want the truth.’ They mailed me this big box full of about 90 studies into the topic. We realised pretty quickly they were almost all very poor quality with almost no methodology. Maybe five or six were usable.”

Gobet set out to discover once and for all whether playing chess can have a positive impact on other areas of cognitive ability, particularly those that similarly combined “intelligence with working memory”. Unlike the studies in the box, Gobet and his team applied scientific conditions – properly sized control groups, placebos, standard deviations. “The conclusion we came to was that playing a lot of chess makes you very good at chess,” he says. “And no evidence for anything else.”

You might think this would have sent shockwaves through the chess community, who’d been using this particular piece of propaganda for years. Instead, fingers were placed firmly in ears. “They basically totally ignored us,” Gobet says. “Every year I get invited to conferences and I often tell the same story. Sometimes they get sick of hearing it and talk about other things. There are still reports being published today claiming chess is great for mathematic intelligence, working memory capacity, Alzheimer’s – everything. But there’s no evidence.”

Chess may not make us smarter in a cognitive sense, but what about the idea it can help us learn to understand and master our feelings better?

“It’s possible,” Gobet says, “Although there’s absolutely no data about that.” He agrees chess is an unusually emotive game. “If you do an experiment and ask people to propose the best move in any position, they often use very emotional terms: ‘This move is disgusting, this move is lovely.’ Clearly, chess generates powerful emotions, especially when you’re losing. People hate losing at chess. You can speculate that chess teaches us a few simple things, like learning to lose graciously, to think before you move and so on. I think it’s more just a way to reveal innate abilities that people have. It’s going to reveal whether you’re resilient or not, if you can manage your emotions.”

Or perhaps it can be a way to chart your personal growth in these things. The boy I was at 12, losing in front of my father, or the man I was at 26, writing it off as a waste of time after each defeat, were not as emotionally resilient as me today, whose Elo (chess-rating system) rating lingers stubbornly in the “class D” range (one step above total novice), but keeps playing anyway. This maturity may be unsurprising, but that doesn’t mean it is not worth observing: self-care is about celebrating and viewing yourself with kindness.

Which leads me to another thing I value about chess. Beneath the cut and thrust of attack and defence, it is also a curious exercise in empathy – for yourself, but also your opponent. Even when you’re playing an anonymous stranger on the internet you can intuit something of their emotional state within a few moves: what opening they choose (or how they respond to yours); how quickly they move; how boldly they exchange material (pieces). Each game has a distinct texture and emotional arc. To the best of my knowledge, no one says this about Boggle.

I asked my father once if my grandfather ever struggled with his mental health. Difficult or unpleasant emotions were taboo in my grandparent’s household. The only self-help they knew was the stiff upper lip, an example which has extended down the family like ivy covering a crumbling wall. He told me there had been a period when he was a child, not discussed during or since, when Grandad took to bed for weeks in a closed off room with what was euphemistically described by everyone at the time as “nerves”. I struggled to picture it.

Later, when we cleared out his house, we found piles of Grandad’s chess books with pencil notes scribbled in the margins where he taught himself opening theories, just as today I spend hours watching “How to DESTROY opponents with the Sicilian Defence!” tutorials by Russian YouTubers. My grandfather lived and died before we had a shared language for the mental health struggles that are also part of his legacy to me, but chess was a journey he set me on which we undertook in the same way, decades apart. I would love to be able to ask him what relief, if any, he got from this infinitely joyful, endlessly maddening game; whether it was his refuge, too.

Perhaps, like me, he appreciated how the game functions as a handy metaphor for life. You start with endless options laid out in front of you, fumble some of your earliest moves, battle through a complicated and difficult middle passage before, eventually, entering a final stretch in which the pieces and the clock start to run out. There will always be better players, silly blunders, missed wins. All you can do is make the best move you can, and when things really go wrong, try and find the will to reset the board and go again.

‘We got quite crazy with it’: Inside Formula 1’s driver chess club



Formula 1 knows all too well just what a game-changer a Netflix series has been for its profile, enjoying a boom off the back of Drive to Survive’s success.


But it is not the only sport or pastime to enjoy such a surge. In October 2020, The Queen’s Gambit became a hit on Netflix, based on the 1983 novel about a female chess prodigy, played by Anya Taylor-Joy, who rises to become the greatest player in the world.

It resulted in a massive swell in interest for chess. Retailers reported sales for chessboards were up as much as 1,000%, according to The New York Times, while new sign-ups to chess.com, one of the world’s biggest online chess websites, were seven times greater than usual.

But it was not only the general public who entered 2021 with a heightened interest in playing chess, which, along with golf and padel, has become one of the major new hobbies for F1 drivers this year.

Ferrari drivers Charles Leclerc and Carlos Sainz Jr are the two drivers who have taken chess the most seriously this year. As well as excelling on-track as team-mates, helping lead Ferrari to third place in the constructors’ championship ahead of McLaren, Sainz and Leclerc have also become good mates off-track. It’s given a youthful, fresh feel to the atmosphere at Maranello.

Chess is an interest that has always been with Leclerc, but as he and Sainz looked for something to do during the quiet periods at the start of the season, it quickly got competitive.

“I’ve actually always been into it, I always liked chess as a child,” Leclerc told Motorsport.com.

“I think it was during all the media days at the beginning of the year, we didn’t know what to do and I was playing chess, and he saw me, and said OK, I’m downloading this.

“We got quite crazy with it in the first part of the year. We played against each other, and we’ve never stopped.”

It was a new obsession for Sainz in particular. “He freaking loves his chess with Charles,” said former McLaren team-mate Lando Norris. “I think I might have beaten him in the first game - then I just quit! I might be wrong, he’d probably tell you I’m lying…

“He was playing like hours and hours of it, him and Charles. I never knew he played before.”

From flights between races to between sessions in the car, and even during the lengthy rain delay at the Belgian Grand Prix, Leclerc and Sainz have been glued to their phones playing each other using an app.


And unsurprisingly, it has become incredibly competitive. In a video for Autosport earlier this year, Leclerc and Sainz debated who was better at chess and won games more often.

“Today we played on the plane, and it was 2-2,” Sainz told Leclerc. "And you didn’t want to play the last one. So if anything… I had the upper hand.”

“No, no,” replied Leclerc. “Remember Spa?” Sainz claimed he lost because he was so focused on the race.

“He’s very good at chess in the night, so whenever we come back from races from 9pm onwards, he’s very good,” said Leclerc. “But in the morning to the evening, I’m much better.”

But Leclerc and Sainz are not the only drivers to have gotten hugely into chess this year. Between sessions and various commitments down at Haas on race weekends, Mick Schumacher is another driver who will typically be found playing the game with any free time available.

A chess board has become part of Schumacher’s essential kit to take with him to races, giving him the chance to sit and play to unwind. Schumacher typically plays with Kai Schnapka, a physio who worked with Michael Schumacher towards the end of his F1 career before linking up with Mick in junior categories. Schumacher also played some games with Timo Glock, but is yet to play the Ferrari drivers.

Yet it was only by accident that Schumacher really got into chess. “We have a chess board at home, we’ve always been playing it here and there, but never properly,” Schumacher told Autosport/Motorsport.com.

“We were very big into backgammon, Kai and I. And then we actually stopped playing - we forgot our backgammon board, and the only thing we had was chess, so we started playing chess!

“Then for a time, we were mixing chess and backgammon, and now basically we just play chess. It’s fun, I beat him the whole time!”

Chess is something Schumacher has found himself improving at as the year went on. “At the beginning of the year I was losing most of them,” he said. “Then for some reason I’ve understood the game a bit better and started winning most of them.”

That kind of mental improvement is exactly the benefit Schumacher sees in test. Back in May, he discussed the benefit of playing such games in an interview with GP Racing.

“I feel like these games kind of bring focus back, as you always have to be switched on with your mind,” Schumacher said. “In a weekend, I always want to be mentally ready for every challenge that comes.”

Next year’s 23-race season is set to give drivers more time than ever on the road, meaning more flights and more periods at racetracks to fill between their racing duties - and for F1’s unofficial but growing chess club, perhaps some more members.

Resolving a Dangerous Conundrum: Earthquake Depth Impacts Potential Tsunami Threat

Tsunami Illustration

Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis.

Research led by University of Hawai‘i (UH) at Manoa scientists provides new insight that connects the characteristics of earthquakes—magnitude, depth where two tectonic plates slip past each other and the rigidity of the plates involved—with the potential size of a resulting tsunami.

Previous researchers identified a special class of events known as tsunami earthquakes, which produce disproportionately large tsunamis for their magnitude. Kwok Fai Cheung, professor of Ocean and Resources Engineering in the UH Manoa School of Ocean and Earth Science and Technology (SOEST), Thorne Lay from the University of California – Santa Cruz, and co-authors discovered a straightforward explanation for this conundrum. Their findings were published recently in Nature Geoscience.

How a Tsunami Works

Using computer models, the team incorporated physical processes that produce earthquakes and tsunamis with a wide range of observations of real-world events, including those classified as tsunami earthquakes. The model results demonstrated that for a given earthquake magnitude, if the rupture extends to shallow depth in the less rigid part of the plate, the resulting tsunami is larger than if the rupture is deeper.

“In a subduction zone, the upper plate is thinner and less rigid than the underthrusting plate near the trench,” explained Cheung. “A concentrated near-trench or shallow rupture produces relatively weak ground shaking as recorded by seismometers, but the displaced water in the overlying deep ocean has enhanced energy and produces shorter tsunami waves that amplify at a high rate as they move toward the shore.”

“Earthquake and tsunamigenic processes are complex, involving many factors that vary from one event to another,” said Lay, professor of Earth and Planetary Sciences at UC Santa Cruz. “We utilized a simplified numerical model to isolate key earthquake parameters and evaluate their importance in defining tsunami size.”

Tsunami Damage

On September 29, 2009, a tsunami caused substantial damage and loss of life in American Samoa, Samoa, and Tonga. The tsunami was generated by a large earthquake in the Southern Pacific Ocean. Credit: NOAA

Having verified that the presence of shallow earthquake rupture can be a more significant factor than the earthquake magnitude for the resulting tsunami size led the researchers to an important question: Can earthquake magnitude continue to be used as the primary indication of potential tsunami impacts?

“The practice of using earthquake magnitude to estimate potential tsunami threat has led to poor predictive capability for tsunami impacts, and more information about the source is required to do better,” said Cheung.

An important aspect of this interdisciplinary research is the synergy of expertise in seismology, with Lay, and tsunamis, with Cheung’s research group, applied to a large set of observations. This study motivates development of new seismological and seafloor geodesy research that can rapidly detect the occurrence of shallow rupture in order to achieve more reliable tsunami warning.

While shorelines throughout the Pacific Ocean and along the “Ring of Fire” are vulnerable to tsunamis, the situation is most critical for coastal communities near the earthquake, where the tsunami arrives quickly—when detailed information about the earthquake is not yet available.

Cheung and Lay continue their collaboration to investigate prehistorical, historical, and future tsunami events to better understand the hazards posed to coastal communities and enable more accurate warning systems.

Tsunamis' magnetic fields are detectable before sea level change

A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and could improve warnings of these giant waves.

Tsunamis generate magnetic fields as they move conductive seawater through the Earth's magnetic field. Researchers previously predicted that the tsunami's magnetic field would arrive before a change in sea level, but they lacked simultaneous measurements of magnetics and sea level that are necessary to demonstrate the phenomenon.

The new study provides real-world evidence for using tsunamis' magnetic fields to predict the height of tsunami waves using data from two real events—a 2009 tsunami in Samoa and a 2010 tsunami in Chile—that have both sets of necessary data. The new study was published in AGU's Journal of Geophysical Research: Solid Earth, which focuses on the physics and chemistry of the solid Earth.

The study confirms the magnetic field generated by a tsunami arrives ahead of  and that its magnitude can be used to estimate the tsunami's wave height. How much earlier the magnetic field arrives depends on water depth, but in their results, the study authors found the early arrival time to be about one minute prior to sea level change over a 4,800-meter deep sea.

This information could provide earlier disaster warning if incorporated into tsunami risk models, potentially saving lives.

"It is very exciting because in previous studies we didn't have the observation [of] sea level change," said Zhiheng Lin, senior study -author and a geophysicist at Kyoto University. "We have observations [of] sea level change, and we find that the observation agrees with our magnetic data as well as theoretical simulation."

The research team looked at simultaneous measurements of sea level change from seafloor pressure data and magnetic fields during the two tsunamis. They found that the primary arrival of the magnetic field, similar to that of the beginning of a seismic wave, can be used for the purpose of early tsunami warning. The tsunami-generated magnetic field is so sensitive that even a wave height of a few centimeters can be detected.

"They did something that basically needed to be done," said Neesha Schnepf, a researcher of geomagnetics at the University of Colorado, Boulder who was not involved in the study. "We've needed a study that compared the magnetic field data with the sea level change from the pressure data, and I'm pretty sure they're the first to really compare how well the sea level from magnetic  matches the sea level from pressure, so that's definitely very useful."

When the researchers compared the horizontal and vertical components of the tsunami  with sea level change, they found that both components can precisely predict tsunami  change, if models include good estimates for ocean depth and the electrical structure below the seafloor.

This relationship between magnetic fields and wave height can be used to improve tsunami source models, which estimate the initial sea surface topography of a tsunami and then predict water wave arrival time and wave height—important data for informing disaster readiness and response.

The difficulty of maintaining already limited observational stations means these types of data from tsunamis are often not available. Furthermore, these findings only apply in deep-sea and not coastal environments, where deep water in the region filters out environmental noise to allow the  signal to be detected.

However, providing warning for these severe events—which have the potential to cause intense damage to large areas—makes the predictions worthwhile, said Lin.

"I think the practical goal would be if your ability to model tsunamis is so improved … you could come up with much better predictions of what areas might need to be warned [and] how badly it might hit certain places," Schnepf said.

Candy Palmater, 'The Candy Show' and 'Trailer Park Boys' Star, Dead at 53



By ANDREW ROBERTS - December 26, 2021

Canadian comedian Candy Palmater is dead at the age of 53. CBC News confirmed the tragic report with the comedian's partner and manager Saturday, with Denise Tompkins sharing Palmater had passed peacefully at her home in Toronto. "I have few words. Candy passed away today at home suddenly," a post from Tompkins read. "I will post information soon."

According to CBC News, no cause of death was made official, with the outlet adding that The Candy Show star had been sick and hospitalized in recent weeks. She had been recently discharged, however. A virtual public service will be organized for fans and friends to attend, with no date announced just yet.



Palmater was the creator and host of The Candy Show on APTN and appeared as a frequent co-host on CTV's The Social. She also appeared and acted in other series, including the popular Trailer Park Boys franchise.

CBC also noted Palmater's contributions to the network. She had appeared as a panelist on CBC Canada Reads in 2017, narrated the series True North Calling and hosted The Candy Palmater Show on CBC Radio One.

"Candy was an incredible talent but also a truly special person," CBC News general manager Susan Marjetti said. "It is such a loss. Another light has gone out in the world today."

Palmater was a shining example for the Indigenous community in Canada as a member of the Mi'kmaw Nation from New Brunswick and a vocal member of the LGBTQ community who described herself as "a gay, native, recovered-lawyer-turned-feminist-comic who was raised by bikers in the wilds of northern New Brunswick." Palmater previously worked for the Nova Scotia government as a lawyer and lived in Halifax for nearly 30 years.



The comedian had just finished writing her autobiography, which will be published in 2022. Many famous names chimed in on the Instagram announcement, sharing their thoughts and memories of the comedian. "My heart is breaking. What a light she was in all our lives," Melissa Grelo wrote. "What a Major loss. I learned so much from her. Sincerest condolences," Jamar McNeil added. "Sending all our love to you Denise and Pearl," Bif Naked wrote.
Sarah Weddington, attorney who won Roe v Wade abortion case, dies aged 76

Susan Hays, a Democratic candidate for Texas agriculture commissioner, announced the news on Twitter on Sunday. The Dallas Morning News confirmed it.

“Sarah Weddington died this morning after a series of health issues,” Hays wrote. “With Linda Coffee she filed the first case of her legal career, Roe v Wade, fresh out of law school. She was my professor … the best writing instructor I ever had, and a great mentor.

“At 27 she argued Roe to [the supreme court]. (A fact that always made me feel like a gross underachiever.) Ironically, she worked on the case because law firms would not hire women in the early 70s, leaving her with lots of time for good trouble.”

The court ruled in Roe v Wade in 1973. Nearly 50 years later the right it established is under threat from a supreme court packed with hardline conservatives, in part thanks to a Texas law which drastically restricts access and offers incentives for reporting women to authorities.

In 2017, speaking to the Guardian, Weddington predicted such a turn of events.

“If [Neil] Gorsuch’s nomination is approved, will abortion be illegal the next day? No. One new judge won’t necessarily make much difference. But two or three might.”

After steering Gorsuch on to the court – and a seat held open by Senate Republican leader Mitch McConnell when Barack Obama was president – Donald Trump installed Brett Kavanaugh and Amy Coney Barrett. Barrett replaced the late Ruth Bader Ginsburg, a champion of women’s rights

Weddington found her way to Roe v Wade soon after graduating from law school at the University of Texas. Represented by Weddington and Coffee, Norma McCorvey became the plaintiff known as “Jane Roe” in Roe v Wade. McCorvey became an evangelical Christian and opponent of abortion. She died in 2017.

In her Guardian interview, Weddington discussed arguing the case in federal court. “I was very nervous,” she said. “It was like going down a street with no street lights. But there was no other way to go and I didn’t have any preconceived notions that I would not win.”

She won, but the case continued.

“Henry Wade, the district attorney, unwittingly helped us,” she said. “At a press conference, he said, ‘I don’t care what any court says; I am going to continue to prosecute doctors who carry out abortion.’ There was a procedural rule that said if local elected officials continue to prosecute after a federal court had declared a law unconstitutional, there would be a right to appeal to the supreme court.”

Before the court in Washington, Weddington said, “it was impossible to read the justices’ faces. The attorney on the other side started by saying something inappropriate about arguing a case against a beautiful woman. He thought the judges would snicker. But their faces didn’t change a bit.

“I had to argue it twice in the supreme court: in 1971 and again in 1972. On 22 January 1973 I was at the Texas legislature when the phone rang. It was a reporter from the New York Times. ‘Does Miss Weddington have a comment today about Roe v Wade?’ my assistant was asked. ‘Why?’ she said. ‘Should she?’

“It was beginning to be very exciting. Then we got a telegram from the supreme court saying that I had won 7-2 and that they were going to airmail a copy of the ruling. Nowadays, of course, you’d just go online.

“I was ecstatic, and more than 44 years later we’re still talking about it.”

Weddington later revealed that she had an abortion herself, in 1967. “Just before the anaesthesia hit,” she said, “I thought: I hope no one ever knows about this. For a lot of years, that was exactly the way I felt. Now there’s a major push to encourage women to tell their stories so people will realise that it is not a shameful thing. One out of every five women will have an abortion.”

Weddington predicated that “whatever else I do in my life, the headline on my obituary is always going to be: ‘Roe v Wade attorney dies.’”

In fact she achieved much more, as Hays detailed in her tweets on Sunday. “Those career doors shut to her led her to run for office, getting elected as the first woman from Travis county in the [Texas legislature] in 1972 (along with four other women elected to the House: Kay Bailey, Chris Miller, Betty Andujar and Senfronia Thompson).

“… She was general counsel of the United States Department of Agriculture under [Jimmy] Carter and enjoyed her stint in DC. Federal judicial nominations for Texas were run by her as a high-ranking Texan in the administration.

“A Dallas lawyer she knew sought a bench. She had interviewed with him while at UT law. He’d asked her, ‘What will we tell our wives if we hire you?’ She told him he was wasting their time and hers and walked out of the interview. He did not get the judgeship.

“Ever the proper preacher’s daughter she would never tell me who the lawyer was. People don’t know that about Sarah. She was SUCH a proper Methodist minister’s daughter. One of the few people I couldn’t cuss in front of.”

Hays also paid tribute to Weddington as a teacher and a member of a “Great Austin Matriarchy” which also included the former Texas governor Ann Richards and the columnist Molly Ivins.

In her Guardian interview, Weddington indicated she was at peace with being remembered for Roe v Wade.

“I think most women of my generation can recall our feelings about the fight,” she said. “It’s like young love. You may not feel exactly the same, but you remember it.”

Thomas Lovejoy, a well-known American conservation biologist who coined the term “biological diversity” in 1980, died on December 25 at the age of 80. Lovejoy, who lived in northern Virginia, spent more than 50 years working in the Amazon rainforest, founding the nonprofit Amazon Biodiversity Center and bringing worldwide attention to the threats of tropical deforestation. In 1971, he received his first grant from the National Geographic Society, becoming an Explorer at Large in 2019.

“To know Tom was to know an extraordinary scientist, professor, advisor, and unyielding champion for our planet,” said Jill Tiefenthaler, the Society's CEO, in a statement. “He was also a consummate connector, helping bring people and organizations together to preserve and protect some of our most fragile ecosystems and cornerstone species.”

In 1980, he also published the first estimate of global extinction rates, correctly projecting that by the early 21st century a huge number of species would be lost forever. Lovejoy, who held a Ph.D. in biology from Yale University, advised three administrations, the United Nations Foundation, the World Bank, and other organizations on how to protect species and advance the field of conservation biology. Since 2010, Lovejoy served as a professor in environmental science and policy at George Mason University in Virginia.

“Tom was a giant in the world of ecology and conservation,” Enric Sala, a National Geographic Explorer in Residence. “But most importantly, he was a wonderful mentor and extremely generous with his students, colleagues, and friends.”

Despite his focus on some of the world’s toughest environmental challenges, Lovejoy remained an optimist. “We all have an interest in fixing this before it gets badly out of hand, and it’s getting close to that,” Lovejoy told National Geographic in 2015, speaking about climate change. “There are things we can do together. There are energy and innovation possibilities. There are biological solutions that would benefit everyone.”
Why Canada gets less for more when it comes to building transit

OTTAWA -- In early September, Conservative candidate Jennifer McAndrew stood outside a suburban Ottawa transit hub in the battleground riding of Kanata-Carleton to make a major campaign promise.

“A Conservative government will support and prioritize Phase 3 of the LRT extension right here to Kanata and beyond,” a smiling McAndrew said in a video posted to her Facebook page on Sept. 2, just as the campaign was heating up.

Not a day later, her Liberal opponent, Jenna Sudds, posted her own video to make the very same promise.

While some transit advocates would be overjoyed to see cross-party commitments to build new light-rail infrastructure, it was a disappointment to Toronto transit researcher Stephen Wickens who spent more than a year warning governments against those kind of campaign promises.

The reason is that Canada pays a higher price to build light-rail transit compared to our international counterparts, driven chiefly by the depth of underground tunnels, the grandiosity of the stations and labour costs.

But several experts agree it has just as much to do with something else: politics.

“That's the heart of it,” said Wickens, who authored an investigative study on the soaring cost of Toronto subway projects commissioned by the Residential and Civil Construction Alliance of Ontario last year.

Alon Levy, a Berlin-based transit researcher and writer, calculated that globally, the median construction cost for an urban subway was less than $300 million per kilometre in 2019.

But in Canada, the costs seem to go off the rails.

By Levy's calculations, Toronto's Ontario Line should cost $735-million per kilometre. The Blue Line extension plan in Montreal? About $775-million per kilometre. Vancouver's Broadway SkyTrain seems almost reasonable at nearly $500-million per kilometre.

Political meddling at all levels of government - by all parties - can cause a knock-on effect on the price tag of projects.

For example, the cheapest tunnelling method is also the most annoying for the neighbours, so local councillors will up the cost to avoid complaints from constituents.

Just over a decade ago, Vancouver opted for a cheaper tunnelling option when it built the 19-kilometre Canada Line by digging a trench at street level and covering the top. The cut-and-cover method, as it's known, led to big savings, but also disruptions, controversy and even lawsuits.

“The memories apparently remain so unpleasant that city leaders have made clear the Broadway Line will be entirely tunnelled, even with project estimates running at about $500 million per kilometre, or about 4.5 times what was paid for the Canada Line,” Wickens wrote in his report.

Political promises can also lock governments into commitments that may not offer the best value. As a 2019 study by the Institute of Municipal Finance and Governance put it, the best projects based on the available evidence take a back seat to political considerations. Civil servants are forced then to give what researchers dub “decision-based evidence” to justify a political promise.

“Who is a lowly engineer to say 'we don't actually need that' or 'let's cut this station,' or 'I know you've promised this interest group something so you need to break that promise because that's going to cost us another half a billion dollars,”' said Levy in an interview with The Canadian Press.

It's not just a Canadian phenomenon.


Levy and other researchers at the Marron Institute of Urban Management at New York University have found Canada, the United Kingdom, Australia and United States overpay compared to peer counties like Spain, Italy and France.

Marco Chitti, a Montreal-based associate researcher on the project, said one domestic factor that may drive up costs is our federal political system that offers significant power to single parties trying to win votes from the public.

He said parliaments of other nations are afforded more power to water down proposals from the ruling party and get more bang for their buck.

Another problem is that Canadian cities and provinces often lack the in-house expertise to offer technical advice and oversee projects, Chitti said. He pointed to Italy where civil servants with technical expertise draw up detailed, costed plans before politicians make any commitments.

Chitti said the path to lowering costs on transit projects starts with admitting there is a problem that needs fixing.

“Most politicians in Canada are not aware that Canada has a huge problem, a huge, tremendous problem on cost,” Chitti said.

“I really hope that in a couple of years there will be much more discussion in Canada about the fact that we have ballooning costs, and that they are really out of control.”
Wind Turbines Are Using Cameras and AI to See Birds –And Shut Down When They Approach

By Good News Network
-Dec 25, 2021


Wind power is a powerful tool for reducing carbon emissions that cause climate change. The turbines, however, can be a threat to birds and bats, which is why experts are looking for—and finding—ways to eliminate the danger.

The US government has allocated $13.5 million to look for solutions. But, already a Boulder, Colorado company has produced a camera- and AI-based technology that can recognize eagles, hawks and other raptors as they approach in enough time to pause turbines in their flight path.

Their tool, called IdentiFlight, can detect 5.62 times more bird flights than human observers alone, and with an accuracy rate of 94 percent. https://www.identiflight.com/

Using high-precision optical sensors, the system calculates a bird’s speed and flight trajectory, and if it is on a collision path with a turbine, a signal is sent to shut that turbine down.

Winning an award for its performance in Australia, the tracking system was installed in 2018 at a Tasmanian facility and was found to cut eagle deaths at the Cattle Hill Wind Farm by more than four-fifths.

Each day, signals have shut-down their movement an average of 400 times—across the field of 48 turbines—for two to three minutes each time.

Across the globe, Duke Energy in Wyoming is employing the same technology with impressive results at its Top of the World Windpower Project.

The IdentiFlight network of camera units watch for bald and golden eagles. When a camera detects an approaching object, the system determines whether it’s an eagle within seconds.

Top of the World—named for a ridge where golden eagles roost—was the first wind site to use the technology. In 2014, IdentiFlight’s manufacturer, Boulder Imaging, used Top of the World for testing after eagles fatalities left the company in violation of the Migratory Bird Treaty Act.

IdentiFlight’s cameras – Duke Energy

47 units made of eight wide-angle cameras now constantly scan the sky to monitor all 110 turbines. The camera unit is mounted to the top of a 30-foot pole and powered by software that learns and improves with each photo taken, as ornithologists vet previously identified birds.

An independent study conducted in 2020 by The Peregrine Fund, Western EcoSystems Technology, and the US Geological Survey, showed an 82 percent reduction in eagle deaths at the site, which is located in Glenrock.

Bird lover and director of National Audubon Society’s Clean Energy Initiative, Garry George, admits, “Our own science shows that climate change is by far the biggest threat to birds and the places wildlife need to survive.”

“IdentiFlight will make it possible to combat the worst effects of climate change and protect the birds we love in the process.”

Indeed, a 2009 study using US and European data on bird deaths analyzed the number killed per unit of power generated by wind power vs fossil fuel and nuclear, estimating that for every bird killed by a turbine, nuclear and fossil fuel powered plants killed 2,118.

Eagles have been capable of adapting, too. Some of the raptors living at Top of the World have been on the site for years, and have had no issues avoiding the blades.

Duke Energy announced it is installing IdentiFlight at Frontier Windpower II in Oklahoma and Wyoming’s Campbell Hill site.


INNOVATION
HOW A 195-YEAR-OLD DISCOVERY COULD BUILD THE FUTURE OF ENERGY



The need to transition to clean energy is apparent, urgent, and inescapable.


JAN-HENDRIK PÖHLS

THE NEED to transition to clean energy is apparent, urgent, and inescapable. We must limit Earth’s rising temperature to within 1.5 C to avoid the worst effects of climate change — an especially daunting challenge in the face of the steadily increasing global demand for energy.

Part of the answer is using energy more efficiently. More than 72 percent of all energy produced worldwide is lost in the form of heat. For example, the engine in a car uses only about 30 percent of the gasoline it burns to move the car. The remainder is dissipated as heat.

Recovering even a tiny fraction of that lost energy would have a tremendous impact on climate change. Thermoelectric materials, which convert wasted heat into useful electricity, can help.

Until recently, the identification of these materials had been slow. My colleagues and I have used quantum computations — a computer-based modeling approach to predict materials’ properties — to speed up that process and identify more than 500 thermoelectric materials that could convert excess heat to electricity, and help improve energy efficiency.

The transformation of heat into electrical energy by thermoelectric materials is based on the “Seebeck effect.” In 1826, German physicist Thomas Johann Seebeck observed that exposing the ends of joined pieces of dissimilar metals to different temperatures generated a magnetic field, which was later recognized to be caused by an electric current.

Shortly after his discovery, metallic thermoelectric generators were fabricated to convert heat from gas burners into an electric current. But, as it turned out, metals exhibit only a low Seebeck effect — they are not very efficient at converting heat into electricity.

In 1929, the Russian scientist Abraham Ioffe revolutionized the field of thermoelectricity. He observed that semiconductors — materials whose ability to conduct electricity falls between that of metals (like copper) and insulators (like glass) — exhibit a significantly higher Seebeck effect than metals, boosting thermoelectric efficiency 40-fold, from 0.1 percent to four percent.

This discovery led to the development of the first widely used thermoelectric generator, the Russian lamp — a kerosene lamp that heated a thermoelectric material to power a radio.

ARE WE THERE YET? — 

Today, thermoelectric applications range from energy generation in space probes to cooling devices in portable refrigerators. For example, space explorations are powered by radioisotope thermoelectric generators, converting the heat from naturally decaying plutonium into electricity. In the movie The Martian, for example, a box of plutonium saved the life of the character played by Matt Damon, by keeping him warm on Mars.

In the 2015 film, The Martian, astronaut Mark Watney (Matt Damon) digs up a buried thermoelectric generator to use the power source as a heater.



Despite this vast diversity of applications, the wide-scale commercialization of thermoelectric materials is still limited by their low efficiency.

What’s holding them back? Two key factors must be considered: the conductive properties of the materials, and their ability to maintain a temperature difference, which makes it possible to generate electricity.

The best thermoelectric material would have the electronic properties of semiconductors and the poor heat conduction of glass. But this unique combination of properties is not found in naturally occurring materials. We have to engineer them.

SEARCHING FOR A NEEDLE IN A HAYSTACK —

 In the past decade, new strategies to engineer thermoelectric materials have emerged due to an enhanced understanding of their underlying physics. In a recent study in Nature Materials, researchers from Seoul National University, Aachen University, and Northwestern University reported they had engineered a material called tin selenide with the highest thermoelectric performance to date, nearly twice that of 20 years ago. But it took them nearly a decade to optimize it.

To speed up the discovery process, my colleagues and I have used quantum calculations to search for new thermoelectric candidates with high efficiencies. We searched a database containing thousands of materials to look for those that would have high electronic qualities and low levels of heat conduction, based on their chemical and physical properties. These insights helped us find the best materials to synthesize and test and calculate their thermoelectric efficiency.

We are almost at the point where thermoelectric materials can be widely applied, but first, we need to develop much more efficient materials. With so many possibilities and variables, finding the way forward is like searching for a tiny needle in an enormous haystack.

Just as a metal detector can zero in on a needle in a haystack, quantum computations can accelerate the discovery of efficient thermoelectric materials. Such calculations can accurately predict electron and heat conduction (including the Seebeck effect) for thousands of materials and unveil the previously hidden and highly complex interactions between those properties, which can influence a material’s efficiency.

Large-scale applications will require thermoelectric materials that are inexpensive, non-toxic, and abundant. Lead and tellurium are found in today’s thermoelectric materials, but their cost and negative environmental impact make them good targets for replacement.

Quantum calculations can be applied in a way to search for specific sets of materials using parameters such as scarcity, cost, and efficiency. Although those calculations can reveal optimum thermoelectric materials, synthesizing the materials with the desired properties remains a challenge.

A multi-institutional effort involving government-run laboratories and universities in the United States, Canada, and Europe have revealed more than 500 previously unexplored materials with high predicted thermoelectric efficiency. My colleagues and I are currently investigating the thermoelectric performance of those materials in experiments, and have already discovered new sources of high thermoelectric efficiency.

Those initial results strongly suggest that further quantum computations can pinpoint the most efficient combinations of materials to make clean energy from wasted heat and avert the catastrophe that looms over our planet.
