Winnipeg-born and raised Michael Lang is at the forefront of a technological innovation that can help to change the way neurosurgery is performed and how brain diseases such as Alzheimer’s Disease are treated
By BERNIE BELLAN We’ve often heard that one of the main reasons Manitoba lags behind other provinces when it comes to economic development is because there is both a lack of entrepreneurial capital in this province and innovative individuals who are willing to base their operations here.
Thus, it was refreshing to hear of one young man who not only grew up in Winnipeg, but who has also decided to stay here and work to help turn a company which he co-founded into a successful start-up.
That young man’s name is Michael Lang, 37. I first met Michael when he was in a bar mitzvah class at Temple Shalom with my daughter, Shira. Having grown up in River Heights, the son of Ida and Sherman Lang, Michael attended, in order, Ecole Robert H. Smith, River Heights Middle School, and Kelvin High School.
Michael notes that, as a young boy, he and several other students, including Ben Carr, would go to Hebrew teacher Ethel Amihude’s home for Hebrew lessons. As a side note I should mention that the same day I interviewed Michael for this story, I also received a phone call from Ben Carr, who is now the Member of Parliament for Winnipeg South Centre. When I mentioned to Ben that I had just got off the phone with his former classmate Michael Lang, Ben said to me that, during the rally held in support of Israel on October 10, at which Ben spoke, he was approached by a woman who said, “I’ll bet you don’t remember me. I taught you Hebrew in my home.” Of course, it was Ethel Amihude – and yes, Ben did recognize her immediately.
Returning to Michael Lang – upon graduating from Kelvin High School, Michael enrolled at the University of Winnipeg to study science, with a particular interest in Physics, which is something he’s always loved, he says. Michael went on to complete his Masters and Ph.D. in Physics at the University of Manitoba, he notes, although his he did much of his research at the University of Winnipeg – “a great experience,” he observes.
I asked him how the Physics Department at the University of Winnipeg would compare with other Physics departments in Canada and the US and, although Michael acknowledges that “it’s a small faculty” – maybe 10 professors in total, they definitely “punch above their weight.”
Now, in order to keep this article at a level that would be understandable to most readers (and to this writer as well), I wanted to avoid asking Michael to go into any great detail about what his area of specialty in Physics was, but – just to give you a taste of what it was that he concentrated upon in his studies, here’s a brief excerpt from his bio on the company website (known as tauMEDIS) that he’s helped to found: “Michael received his Ph.D. in Physics from the University of Manitoba with work on hyperpolarized 129Xe gas production for high-precision co-magnetometry.”
The key word in that sentence is “magnetometry,” because it helps to explain how Michael’s research in that field eventually led him into the field of magnetic resonance imaging – or, as the acronym of that term is much more familiar to most of us: “MRI.”
By now, getting an MRI performed for a host of medical issues is something a lot of us expect to have done – and not with undue delays – and when we must wait for an MRI to be performed, which was something greatly exacerbated as a result of Covid disruptions to our medical system, it can be excruciatingly trying.
In the spring of 2020 – shortly after the start of the pandemic, Michael was working as a lab technician at the University of Winnipeg, where he maintained that university’s small animal MRI facility. It was then that the Principal Investigator of the lab, Dr. Melanie Martin, introduced Michael to members of a group working on a novel intraoperative MRI system. Michael would soon after join the group as a post-doctoral fellow, helping to lay the groundwork for what became tauMEDIS.
What is tauMEDIS? According to information available on its website, “Originally formed in 2018, and officially founded in 2023 by a group of Canadian scientists and engineers who are passionate about medical imaging, the name TauMEDIS is an acronym for tau Medical Imaging Solutions…” (tau is a letter in the Greek alphabet that “has significance in both magnetic resonance imaging as well as a variety of neurodegenerative diseases.”)
Although there are a host of other companies active in producing MRI systems, tauMEDIS has developed a particular type of technology in a specialized area of magnetic resonance imaging known as iMRI: “Intraoperative magnetic resonance imaging” or “iMRI,” for short. iMRI is a “method to acquire updated images of the brain throughout a neurosurgical procedure. Neurosurgeons rely on iMRI technology to obtain accurate images of the brain that guide them in removing brain tumors and treating other conditions such as epilepsy.”
Where tauMEDIS is unique in this highly specialized field though, is in its having developed a method to mobilize a full-sized MRI machine that, not only does not require the patient to be moved from the operating table into another room to have an MRI performed, it optimizes the installation process, allowing for retrofitting in existing operating rooms. (There is another company that makes moving magnet iMRI machines, known as IMRIS, that also allows the patient to remain on the operating table during surgery without having to be moved, but incorporating those particular systems into hospitals usually involves making major changes to the infrastructure of existing operating rooms.) The tauMEDIS system, Michael explains, minimizes renovations, and drastically reduces installation time in existing operating facilities.
“We developed a method to mobilize the MRI on a floor-moving track-based vehicle,” he says. “Essentially it’s a high-precision tank-like device that brings the MRI system to the patient undergoing neurosurgery,” providing the surgical team with updated images of the brain throughout the procedure.
tauMEDIS was just recently incorporated in Manitoba (six months ago). In March of this year its prototype machine received approval from the Food and Drug Administration in the US.
Now, in addition to his role as the company’s Chief Technology Officer, Michael, along with the other principals in the company, have found themselves in the position of having to seek out investment funds for tauMEDIS to commercialize the iMRI system they have developed. The funding would support development of a Winnipeg facility that would begin producing actual systems for sale.
“We just recently had our first showing at the Congress of Neurological Surgeons,” Michael says, “and now we’re in the fund-raising phase.”
I asked him how much money they’re seeking, and he says, “$200,000 to start.” I said to him that doesn’t seem like a lot to ask for and that I wondered whether having this article appear in this paper might not be just what it would take to elicit a positive response from some would-be investors.
Further, Michael notes that the goal of tauMEDIS “is to set up a local facility, combining manufacturing and R&D of tauMEDIS products, all located right here in Manitoba. We hope to attract and develop talent, growing the Winnipeg medical device sector.” (I should also mention that years ago, when I was writing about the Crocus Investment Fund, I noted that one of the first investee companies for Crocus was that very same IMRIS, to which I previously referred. I asked Michael if he knew whatever became of IMRIS back then since, according to Michael, it has now become very successful. As I recall, the Crocus Fund lost its entire investment in IMRIS. According to Michael, the company is now based in Minnesota. What happened after the Crocus debacle I’m not sure – just another example of a company that had a great idea but, for whatever reason, couldn’t succeed in Manitoba – although it did take off when it relocated elsewhere.)
Not only is tauMEDIS seeking capital to begin producing its iMRI systems, it also has other technological innovations in the works – all in the area of medical imaging. As Michael Lang says, his “goal as Chief Technology Officer is to work with physicians around the world to make advances in medical imaging technology and develop novel solutions” that would dramatically improve patient health outcomes.

Hacker and Fraud Prevention for Online Gambling Profiles
Safeguard your online casino & sports betting accounts from cyber threats
Follow these 10 vital steps to reinforce your online gambling profile by enabling two-factor authentication, using VPNs, unique passwords and more.
With the global online gambling market projected to reach over $100 billion by 2026, securing your online casino and sportsbook accounts is more critical than ever. As digital wallets swell with winnings so too does the motivation for cybercriminals to steal credentials and loot accounts.
#1. Activate Two-Factor Authentication
Topping the list is two-factor authentication (2FA) – requiring two credentials to login instead of one at FanDuel. Often this entails providing your password plus a one-time code sent via SMS or email.
Per an Oracle study, implementing 2FA would have thwarted 99% of historical cyber attacks that involved stolen credentials.
Most regulated online gambling sites offer 2FA, accessible under account settings. Turn it on immediately for stronger defense.
#2. Never Reuse or Recycle Passwords
A cardinal sin is recycling the same password across multiple sites or services. Once one account is breached, cyber thieves can access more accounts using that same password.
To avoid this, every account deserves a unique, strong password. For simplicity, utilize a password manager app to randomly generate and store site-specific passwords.
#3. Install a VPN for Public Wi-Fi Access
When playing online casino games on shared/open wireless networks, your data flows openly and risks interception. That’s where virtual private networks (VPNs) come in.
VPNs encrypt all network traffic to and from your device. This protects your gambling activity and account credentials from Wi-Fi eavesdroppers. VPNs also disguise your IP address.
Some top-rated services include NordVPN, ExpressVPN and CyberGhost.
#4. Keep Software Updated & Run Anti-Virus Scans
You must keep computers and mobile devices updated with the latest OS and security patches. Postponing critical updates leaves open dangerous holes that malware exploits.
Likewise run reputable anti-virus scans to catch viruses attempting to infiltrate systems and spy on login credentials for financial accounts.
#5. Verify the Security & Encryption of Sites
When signing up at online betting sites and casinos, verify the legitimacy of their security measures:
- Confirm the address starts with HTTPS, not HTTP
- Check that data transmissions are encrypted using at least 128-bit SSL
- Ensure site has proper licensing
- Review privacy policy for data storage and sharing
Reputable sites will display trust badges from companies like Norton and TrustE.
#6. Avoid Account Sharing
While tempting to give friends or relatives access to funded accounts, sharing login credentials is extremely risky. You lose control over deposits/withdrawals while exposing yourself to potential theft.
Instead, gift deposits to other player accounts or refer them to open their own secure accounts.
#7. Beware Account Takeover Scams
Exercise caution if contacted unexpectedly about unusual account activity. Savvy scammers will pretend a breach occurred to trick you into handing over your username and password.
If concerned about account integrity, directly access the site yourself and contact customer support – don’t click any links in unsolicited emails.
#8. Monitor Financial Statements
Carefully review online betting account and credit card statements to detect unauthorized transactions right away. Dispute unrecognized activity ASAP to limit losses.
For further vigilance, some banks offer real-time purchase alerts via email or SMS.
#9. Don’t Save Payment Info
Saving credit card or e-wallet details on gambling sites for faster future deposits also expedites withdrawals – by you and potentially hackers.
Instead, manually enter payment info each time to contain potential damage from any account infiltration.
#10. Create a Secure Email
A strong yet oft-overlooked defense is creating a secure email account strictly for gambling transactions. Keep it completely separate from your personal email to isolate threats.
Use a nickname, enable 2FA and establish a strong password using special characters, numbers, case changes and 15+ letters.
Table: Comparison of Top VPNs for Online Gambling Site Security
| VPN Service | Encryption Standard | Number of Server Locations | Allows P2P Traffic | Number of Simultaneous Connections | Money Back Guarantee |
| NordVPN | AES 256-bit | 5400+ | Yes | 6 | 30 days |
| ExpressVPN | AES 256-bit | 3000+ | Yes | 5 | 30 days |
| CyberGhost | AES 256-bit | 7400+ | Yes | 7 | 45 days |
Fortify Your Online Gambling Fortress
As online casinos and sportsbooks explode in popularity, no player is immune to the growing plague of cyber fraud and account theft.
Guard your profile by enabling two-factor authentication, setting strong passwords, installing critical software updates and more. Also research site security measures and payment options.

Vital Role of True Randomness in Modern Computing
The critical need for true randomness in cryptography, simulations, and more
True randomness is essential for encryption, statistical sampling, simulations, and more computing applications to work effectively. We explore why.
The concept of randomness often evokes thoughts of unpredictability and chance occurrences. However in the world of computing, having access to true randomness is vital for many critical applications to function properly. Without the ability to generate random values and data, key aspects of modern technology simply would not work reliably.
In this article, we will explore what constitutes true randomness from a computational perspective, why it is crucially important, and some of the ways that software and hardware attempt to produce randomness reliably. Gaining insight into this topic highlights the dependence much of digital functionality has on the availability of non-deterministic, uniformly distributed random data.
What Makes Randomness “True”?
For data to be considered truly random from an information theory perspective, values must satisfy key mathematical and statistical qualities, for example at Lucky Seven Casino. True randomness implies meeting three core criteria:
- Uniform distribution — All potential values have an equal probability of occurring so that no bias exists towards certain numbers.
- Independence — The value at any position does not relate to or depends on values at other positions. Previous numbers do not influence future ones.
- Unpredictability — Knowing some values provides no useful information to predict other values. Guessing upcoming numbers is mathematically impossible.
Hence, true randomness requires generated data featuring high entropy (information density) with no observable patterns or correlations over any length or time period analyzed. Values must pass various statisticatests of randomness to qualify. True randomness exists only in specific natural phenomena scientists believe exhibit fundamental uncertainty such as radioactive decay. Computational methods can attempt to produce randomness but technically generate only an approximation usually called pseudo-randomness. However for many practical purposes, computationally generated randomness proves sufficient if it passes robust statistical testing.
Why True Randomness Matters Cryptography
Arguably, the area with the most crucial dependence on true randomness is cryptography. All modern encryption technologies require random number generation to ensure security. Encryption systems work by utilizing random numbers for:
- Key generation
- Initialization vectors
- Salts
- Nonces
- Padding
Any bias, predictability or correlation within random values used for the above purposes significantly compromises encryption protocols and introduces vulnerabilities. With trillions of dollars transferred online daily and vast amounts of sensitive data stored digitally, safeguarding cryptography requires high-quality random number generation rooted in solid entropy sources.
Simulations & Modeling
Outside of security, many more computing applications need randomness to operate correctly per their design intent. Monte Carlo simulations extensively utilize randomness to model complex real-world behaviors by running many iterations with differing random inputs. Financial analysis, climate modeling, nuclear reactions and molecular behavior represent common Monte Carlo simulation applications.
Games, Artificial Intelligence & Machine Learning
Gaming, AI and ML commonly incorporate randomness to increase variation, introduce unpredictability, and improve realism. For example, non-player characters in video games use randomness for movement, dialog and behavior to feel more lifelike and less robotic. AI/ML leverage randomness to train networks more thoroughly against a wider possibility space and build more resilient models less prone to biases.
Generating True Randomness via Hardware
Given the pervasive need for genuine randomness across computing, how do software and hardware reliably produce it? Most systems today use either specialized hardware random number generators or hybrid combinations of hardware and software.
Hardware options utilize the inherent randomness within low-level physical phenomena to produce entropy. Different techniques for generating randomness exist but most hardware implementations focus on three main sources:
- Thermal Noise
- Semiconductor Quantum Physics
- Chaotic Oscillator Outputs
| Generator Type | Description |
| Thermal Noise | Amplifies and extracts random electrical noise from resistor thermal vibrations |
| Quantum Physics | Leverages quantum mechanical properties like photon emission timing from LEDs/lasers |
| Chaotic Circuits | Uses unpredictable oscillator circuit outputs from chaos theory |
Semiconductor-based solutions can generate high bitrates up to 5Gbps using compact modern chip fabrication allowing extensive harvestingof entropy. However these sources derive from complex, random physical processes proving impossible to predict or fully model mathematically. This unpredictability provides excellent entropy quality unattainable via software algorithms alone.
Most general-purpose computers now integrate random number generators within CPUs allowing applications access to decent hardware-based random data. For the highest security use cases, dedicated standalone hardware random number generators exist exceeding >100Gbps speeds. Hence accessing genuine randomness is available today even on common computing devices.
Cryptographically Secure Pseudo-Random Number Generators
While hardware mechanisms utilize hard-to-predict physical phenomena to produce randomness, software solutions must take a different approach. Algorithmically-generated randomness cannot achieve true randomness from a physics perspective. However clever mathematical techniques like cyclical algorithms can generate randomness passing many statistical tests of randomness within their output bit length limits.
Cryptographically secure pseudo-random number generators (CSPRNG) serve as the premier software-based method for generating randomness. CSPRNGs work by repeatedly applying cryptographic primitives like hash or cipher functions on initial random seed values. This process produces a chain of output bits not reproducible without the original seed key. Leading CSPRNG algorithms include:
- Hash_DRBG
- HMAC_DRBG
- CTR_DRBG
Software libraries implement these CSPRNGs so developers can integrate quality randomness into applications with proper seeding. Seeding establishes the initial starting point for randomness generation using an entropy source like hardware random number generators or timing variability.
CSPRNGs allow the production of vast quantities of randomized data for any purpose needed. Compared to hardware mechanisms limited by physics on maximum speeds, algorithms scale boundlessly in the bits created as long as adequate computational power exists.
Yet key differences between software and hardware randomness remain. While CSPRNG outputs pass statistical testing and contain no observable patterns, their pseudo-randomness means given the same seed, the exact same value sequence will generate each time. Also, if a CSPRNG algorithm or implementation has flaws, adversaries could predict and exploit output resulting in compromised security. Still, with proper cryptographic design and regular reseeding, CSPRNGs provide quality randomness for most software needs.
Conclusion
From the above exploration, we see true randomness plays a pivotal role across computing – from cybersecurity to simulations and beyond. While no substitutes for true physically-derived entropy exist, modern hardware and hybrid hardware-software solutions provide abundant randomness for practical usage.
However as computing continues evolving with new technologies like quantum, ensuring high-quality randomness generation tackles emerging information security and system reliability challenges. Access to ample true randomness stands necessary now for current computing functionality and lays the foundation for future innovation.
