Thousands of researchers around the world have been working tirelessly to develop a vaccine to treat the novel coronavirus that has wreaked havoc across the globe.
Now, months after the SARS-CoV-2 virus was first detected in Wuhan, China, researchers are honing in on a possible vaccine.
But, they say it could be two years before any such vaccine would be ready for public consumption.
Challenges to vaccine development
The biggest challenge researchers face when trying to develop vaccines for emerging viruses like SARS-CoV-2 is a lack of information, Dr. Alyson Kelvin, an assistant professor at Dalhousie University’s Toronto campus and a research scientist at the Canadian Centre for Vaccinology, told Global News.
She said because this novel coronavirus only spilled over into the human population a few months ago, researchers were essentially “starting from scratch.”
“We don’t have a clinical picture, we don’t have a genetic signature, we don’t have the protein signature,” she said. “We know nothing about this virus.”
She said scientists have had to study what the virus is made of and how it behaves in order to develop a target.
Dr. Matthew Miller, an associate professor at McMaster University’s department of biochemistry and biomedical sciences, said in general, coronaviruses pose a problem for vaccine development.
He explained that’s because researchers don’t have a very good understanding of what type of protection a vaccine would provide for this type of virus.
“For some vaccines, we know really, really specifically what cells in the immune system, for example, are really important for ensuring that you’re protected,” he said.
He said in some cases, scientists are able to measure “with pretty good confidence” whether a person is going to be protected from a virus or not.
But, this is not the case with SARS-CoV-2, Miller said.
“There are questions about how to generate a good protective response and how to measure that and what you need to measure,” he said. “And so that does pose a sort of significant challenge.”
But, these are not “insurmountable” challenges, said Dr. Natasha Crowcroft, director of the Centre for Vaccine Preventable Diseases at the University of Toronto.
She said it’s “reasonable” to be optimistic that a vaccine will be developed.
“People have tried to develop vaccines before, but never have we put this much effort into trying to find something that will work,” she said. “Never have so many approaches been tried.”
She said scientists are trying both traditional and innovative methods, and are hoping to end up with more than one effective vaccine.
According to Kelvin, the most traditional type of vaccine takes the entire virus and kills it. A patient is then immunized so their immune system can identify the virus before it encounters the live version.
“So, we’re basically educating your immune army to get ready and know what it’s looking for before it has to deal with something that could cause disease,” she said.
This has proven to be a safe and effective type of vaccine for other viruses, Kelvin said, but it takes time to develop.
“We have to get the virus, we have to culture it and make lots and lots of it to kill it,” she said. Researchers then need to confirm the virus has actually been killed, and that the quality of the vaccine is good enough to be given to people, she added.
She said when it comes to SARS-CoV-2, there are a number of other types of trials underway, including protein-based vaccines, RNA vaccines and DNA vaccines. Each has a different timeline.
Kelvin noted a number of trials already appear to be “promising.”
Miller, too, said he is “very confident” researchers will be successful, saying it’s more likely that we end up with “several different vaccines” than none at all.
He said while the proposed two-year timeline is short, it’s “reasonable.”
Miller said it will allow for adequate pre-clinical and clinical trials while also providing manufacturers time to prepare to mass produce and distribute the vaccines.
“All of that takes time,” he said.
What happens if the virus mutates?
Miller added one “encouraging” thing about the novel coronavirus is that it does not appear to be mutating as quickly as other viruses, like influenza.
That means scientists are able to hone in and understand how the virus works without having to adapt to new changes.
Crowcroft explained while it’s unlikely that SARS-CoV-2 will mutate significantly, if a vaccine has been developed, scientists would be able to reformulate it.
She said this would likely be a shorter process than developing the vaccine in the first place because scientists would not be starting from scratch.
This is common practice with the influenza vaccine, she explained.
Kelvin said researchers have already begun working on a pan-coronavirus vaccine, which would be able to treat a wide range of coronaviruses.
She said this vaccine would also account for potential mutations in the virus.
What has the Canadian government said?
Last week, Prime Minister Justin Trudeau announced the government will spend $1.1 billion for a national medical and research strategy that would include research into vaccines, treatments and supports for clinical trials.
He has also repeatedly stressed the importance of developing an effective treatment for the virus, saying the country will not return to “normal” until after a vaccine is developed.
Speaking to reporters on Tuesday, Trudeau said while trials are underway, the government has begun preparing to distribute vaccines once they become available.
“That is something that we are preparing already in terms of manufacturing and production capacity here in Canada because we know that countries around the world will be producing for their own citizens first and we need to be a part of that as well,” he said.
Kelvin said when it comes to supporting this research, Canada has “done a really good job.”
“They were much faster than the U.S. to get money out to where it was needed,” she said.
But, she said it is going to take “a lot of coordination” between the government, scientists and manufacturers in order to produce and distribute the vaccines once they are available.
“We need to have that partnership between scientists and industry to get this out to the whole population,” she said.
Moving forward, Kelvin said she would like to see continued support for this type of research.
Online slots have long been a favorite for casual gamers and seasoned bettors alike, offering simple gameplay combined with the thrill of potential rewards. However, as the landscape of online gaming continues to evolve, a new wave of slot games is emerging—one that incorporates puzzle mechanics into the traditional reel-spinning experience. These puzzle-based slots are changing the way players engage with the game, offering more interactive and challenging gameplay that goes beyond the usual spin-and-win formula.
In this article, we’ll explore how puzzle mechanics are transforming the world of online slots, why they are gaining popularity, and what players can expect from this innovative trend.
The Evolution of Online Slots
A Brief History of Slot Games
Slots have come a long way since the days of mechanical machines with just three reels and a lever to pull. The digital transformation brought these games online, making them more accessible and varied. Early online slot games mimicked the physical versions, with similar symbols and basic gameplay. As technology advanced, developers began incorporating themes, storylines, and special features like bonus rounds and free spins, making online slots more immersive than ever before.
What Are Puzzle Mechanics?
Puzzle mechanics in games are features that require players to solve problems, think strategically, or perform certain actions in a specific sequence to progress. Popular in genres like adventure or mobile games, puzzle mechanics are now finding their way into online slots. Instead of relying solely on luck, players can now enjoy a more engaging and mentally stimulating experience by solving puzzles while they spin the reels.
In puzzle-based slots, players might be required to match symbols in a certain way, clear the board, or complete a specific objective to unlock rewards. These mechanics provide an added challenge, requiring not just chance but also skill and strategy.
How Puzzle Mechanics Enhance Online Slots?
Increased Player Engagement
One of the key reasons puzzle mechanics are gaining popularity in online slots is that they significantly increase player engagement. Slot gacor hari ini can become repetitive after a while, with players simply pressing a button and waiting for the outcome. Puzzle elements, on the other hand, give players more control and decision-making opportunities during gameplay.
By combining skill and chance, puzzle mechanics keep players invested longer. Each spin becomes part of a larger strategy to solve the puzzle, giving players a sense of accomplishment when they succeed.
More Rewarding Experiences
Puzzle mechanics also create a more rewarding experience. In many of these games, completing a puzzle or solving a problem leads to bigger bonuses, extra spins, or unlocking new levels within the game. This contrasts with traditional slots, where payouts are often random and disconnected from the player’s actions.
In puzzle-based slots, players may be able to unlock progressive rewards by completing various stages, making each win feel more earned. The satisfaction of solving a puzzle adds an extra layer of excitement, as it’s not just about hitting the jackpot but also about progressing through the game.
A Shift in Focus: From Luck to Strategy
While luck still plays a significant role in puzzle-based slots, the introduction of strategy adds a new dimension to the gameplay. In traditional slots, outcomes are purely based on chance, with random number generators (RNG) determining the result of each spin. Puzzle mechanics shift the focus by giving players more agency over the game’s outcome.
Examples of Puzzle-Based Slot Games
Popular Titles Leading the Way
Several puzzle-based slot games are already making waves in the industry. These games combine the familiar elements of online slots with puzzle-solving features, creating a unique and exciting experience for players.
Gonzo’s Quest: One of the most popular examples of a puzzle-based slot game, Gonzo’s Quest by NetEnt, incorporates cascading reels and multipliers that increase with each consecutive win. Players must clear symbols to uncover hidden treasures, and the puzzle-like gameplay makes each spin more strategic.
Finn and the Swirly Spin: Another example from NetEnt, this slot uses a spiral mechanic where symbols move in a swirl rather than traditional paylines. Players must clear symbols in a specific order to unlock features, creating a puzzle-like experience that requires more than just pressing spin.
Reactoonz: This game by Play’n GO features a grid layout rather than traditional reels, with symbols that explode and collapse to form winning combinations. Players must think ahead to trigger special bonuses by clearing enough symbols, making the gameplay highly interactive.
These titles are just a few examples of how puzzle mechanics are being incorporated into slot games, offering players more than just a reliance on luck.
Conclusion
Puzzle mechanics are changing the way we play online slots by adding a layer of complexity and interaction that wasn’t previously available. These games offer more engaging, rewarding, and strategic experiences, appealing to both casual players and those looking for a more involved gaming session. As the trend continues to grow, puzzle-based slots will likely become a staple in the world of online gaming, revolutionizing how we think about and play these classic games.

OTTAWA – Bank of Canada governor Tiff Macklem says there is a lot of uncertainty around how artificial intelligence could affect the economy moving forward, including the labour market and price growth.
In a speech in Toronto at the Economics of Artificial Intelligence Conference, the governor said Friday that the central bank is approaching the issue cautiously to get a better understanding of how AI could affect its job of keeping inflation low and stable.
“Be wary of anyone who claims to know where AI will take us. There is too much uncertainty to be confident,” Macklem said in prepared remarks.
“We don’t know how quickly AI will continue to advance. And we don’t know the timing and extent of its economic and social impacts.”
The governor said AI has the potential of increasing labour productivity, which would raise living standards and grow the economy without boosting inflation.
In the short-term, he said investment in AI is adding to demand and could be inflationary.
However, Macklem also highlighted more pessimistic scenarios, where AI could destroy more jobs than it creates or lead to less competition rather than more.
The governor called on academics and businesses to work together to shed more light on the potential effects of AI on the economy.
“When you enter a dark room, you don’t go charging in. You cautiously feel your way around. And you try to find the light switch. That is what we are doing. What we central bankers need is more light,” he said.
