3 win chemistry Nobel; findings led to bestselling drug

Published

5 minute read

STOCKHOLM — Three researchers who “harnessed the power of evolution” to produce enzymes and antibodies that have led to a new bestselling drug and biofuels won the Nobel Prize in chemistry on Wednesday.

Frances Arnold of the California Institute of Technology was awarded half of the 9-million-kronor ($1.01 million) prize, while the other half will be shared by George Smith of the University of Missouri and Gregory Winter of the MRC molecular biology lab in Cambridge, England.

The Royal Swedish Academy of Sciences, which chose the winners, said Arnold, 62, conducted the first directed evolution of enzymes, whose uses include “more environmentally friendly manufacturing of chemical substances such as pharmaceuticals and the production of renewable fuels.”

Smith, 77, developed a method to evolve new proteins and Winter used the method to evolve antibodies, which are disease-fighting proteins in the blood.

The first pharmaceutical based on Winter’s work was approved for use in 2002 and is employed to treat rheumatoid arthritis, psoriasis and inflammatory bowel diseases, the academy said. The chemical name of the drug is adalimumab, which has several trade named including Humira, one of the top-selling drugs in the world.

Smith, speaking to The Associated Press after learning about this Nobel win, credited others for the work that led to his breakthrough.

“Very few research breakthroughs are novel. Virtually all of them build on what went on before. It’s happenstance. That was certainly the case with my work,” he said Wednesday. “Mine was an idea in a line of research that built very naturally on the lines of research that went before.”

Smith said he learned of the prize in a pre-dawn phone call from Stockholm.

“It’s a standard joke that someone with a Swedish accent calls and says ‘You won!’ But there was so much static on the line, I knew it wasn’t any of my friends,” he said.

American Chemical Society president Peter Dorhout praised the Nobel winners, saying “the laureates have used chemistry to accelerate the evolution of natural biological molecules that act as the critical machinery for living organisms.

“The breakthroughs from these researchers enable that to occur thousands of times faster than nature to improve medicines, fuels and other products,” he said.

Experts said the developments for which the winners won the 2018 prize can be more ecological than many other chemical processes.

Enzymes “are what all we organisms use to make our chemicals. So if you can harness enzymes for your own purposes, this is often more environmentally friendly than using heavy metals or toxic substances to make your chemicals,” said Johan Aqvist, a member of the Nobel Committee for Chemistry.

In other Nobel prizes this year, the medicine prize went Monday to James Allison of the University of Texas M.D. Anderson Cancer Center and Tasuku Honjo of Kyoto University, who learned how to release the brakes that cancer can put on the immune system, discoveries that helped cancer doctors fight many advanced-stage tumors and save an “untold” numbers of lives.

Scientists from the United States, Canada and France shared the physics prize Tuesday for revolutionizing the use of lasers in research.

Arthur Ashkin became the oldest Nobel Prize laureate at 96, while Donna Strickland of the University of Waterloo in Canada became only the third woman to win a physics Nobel. Strickland had worked with the third winner, Frenchman Gerard Mourou of the Ecole Polytechnique and the University of Michigan.

The winner of the Nobel Peace Prize is to be announced Friday. The Nobel Memorial Prize in Economic Sciences, honouring Alfred Nobel, the man who endowed the five Nobel Prizes, will be revealed on Monday.

No Nobel literature prize will be awarded this year due to a sex abuse scandal at the Swedish Academy, which choses the winner. The academy plans to announce both the 2018 and the 2019 winner next year — although the head of the Nobel Foundation has said the body must fix its tarnished reputation first.

The man at the centre of the Swedish Academy scandal, Jean-Claude Arnault, a major cultural figure in Sweden, was sentenced Monday to two years in prison for rape.

Kananaskis G7 meeting the right setting for U.S. and Canada to reassert energy ties

Published on

Energy security, resilience and affordability have long been protected by a continentally integrated energy sector.

The G7 summit in Kananaskis, Alberta, offers a key platform to reassert how North American energy cooperation has made the U.S. and Canada stronger, according to a joint statement from The Heritage Foundation, the foremost American conservative think tank, and MEI, a pan-Canadian research and educational policy organization.

“Energy cooperation between Canada, Mexico and the United States is vital for the Western World’s energy security,” says Diana Furchtgott-Roth, director of the Center for Energy, Climate and Environment and the Herbert and Joyce Morgan Fellow at the Heritage Foundation, and one of America’s most prominent energy experts. “Both President Trump and Prime Minister Carney share energy as a key priority for their respective administrations.

She added, “The G7 should embrace energy abundance by cooperating and committing to a rapid expansion of energy infrastructure. Members should commit to streamlined permitting, including a one-stop shop permitting and environmental review process, to unleash the capital investment necessary to make energy abundance a reality.”

North America’s energy industry is continentally integrated, benefitting from a blend of U.S. light crude oil and Mexican and Canadian heavy crude oil that keeps the continent’s refineries running smoothly.

Each day, Canada exports 2.8 million barrels of oil to the United States.

These get refined into gasoline, diesel and other higher value-added products that furnish the U.S. market with reliable and affordable energy, as well as exported to other countries, including some 780,000 barrels per day of finished products that get exported to Canada and 1.08 million barrels per day to Mexico.

A similar situation occurs with natural gas, where Canada ships 8.7 billion cubic feet of natural gas per day to the United States through a continental network of pipelines.

This gets consumed by U.S. households, as well as transformed into liquefied natural gas products, of which the United States exports 11.5 billion cubic feet per day, mostly from ports in Louisiana, Texas and Maryland.

“The abundance and complementarity of Canada and the United States’ energy resources have made both nations more prosperous and more secure in their supply,” says Daniel Dufort, president and CEO of the MEI. “Both countries stand to reduce dependence on Chinese and Russian energy by expanding their pipeline networks – the United States to the East and Canada to the West – to supply their European and Asian allies in an increasingly turbulent world.”

Under this scenario, Europe would buy more high-value light oil from the U.S., whose domestic needs would be back-stopped by lower-priced heavy oil imports from Canada, whereas Asia would consume more LNG from Canada, diminishing China and Russia’s economic and strategic leverage over it.

Poilievre on 2025 Election Interference – Carney sill hasn’t fired Liberal MP in Chinese election interference scandal

Published on

From Conservative Party Communications

Yes. He must be disqualified. I find it incredible that Mark Carney would allow someone to run for his party that called for a Canadian citizen to be handed over to a foreign government on a bounty, a foreign government that would almost certainly execute that Canadian citizen.

 

“Think about that for a second. We have a Liberal MP saying that a Canadian citizen should be handed over to a foreign dictatorship to get a bounty so that that citizen could be murdered. And Mark Carney says he should stay on as a candidate. What does that say about whether Mark Carney would protect Canadians?

“Mark Carney is deeply conflicted. Just in November, he went to Beijing and secured a quarter-billion-dollar loan for his company from a state-owned Chinese bank. He’s deeply compromised, and he will never stand up for Canada against any foreign regime. It is another reason why Mr. Carney must show us all his assets, all the money he owes, all the money that his companies owe to foreign hostile regimes. And this story might not be entirely the story of the bounty, and a Liberal MP calling for a Canadian to be handed over for execution to a foreign government might not be something that the everyday Canadian can relate to because it’s so outrageous. But I ask you this, if Mark Carney would allow his Liberal MP to make a comment like this, when would he ever protect Canada or Canadians against foreign hostility?

“He has never put Canada first, and that’s why we cannot have a fourth Liberal term. After the Lost Liberal Decade, our country is a playground for foreign interference. Our economy is weaker than ever before. Our people more divided. We need a change to put Canada first with a new government that will stand up for the security and economy of our citizens and take back control of our destiny. Let’s bring it home.”
