Morley Hollenberg: The family tradition of entering into medicine continued
By GERRY POSNER Has there ever been a run of doctors in one family like the Hollenbergs? Just as, at one time,, if you thought of baseball champions, the New York Yankees would come to mind, so too it is with medicine and the Hollenberg family.
There sure were – and are, a lot of Hollenbergs who went into medicine. Looking at Eva Wiseman’s history of Manitoba Jewish physicians, ”Healing Lives,” offers a long list of Hollenbergs in the field.
Just think about such legendary names in the original generation of Hollenberg physicians: Mike, Abe, Joe, Charles and the youngest brother in the mix, Jake. As well, there were two women physicians who married into the family: Esther (Gorsey), married to Jake; and Dorothy (Osovsky), married to Joe.
From the five physician brothers flowed yet another eight doctors: Murray and Joan, children of Mike; Morley, son to Jake; Charles, Martin and Barbara, children of Abe; and Joanna and Robert, children of Joe.
Add to those names a member of the third generatiion of Hollenberg doctors: Abe’s grandson, Anthony , now head of the Department of Medicine at Boston University School of Medicine. As well, there are many other practicing Hollenberg physicians apart from the Winnipeg clan who are related.You get the picture.
With all of these accomplished Hollenbergs engaged in medical practices, one of them though took a different route in his career: Morley Hollenberg. He ended up in the research part of the profession rather than in medical practice. His contributions in research are staggering and still continue to this day.
Now, for those of us who are not part of a family business, it might be hard to wrap your head around the pressure, whether direct or indirect, to continue in the business. Morley seemed to have no issues with proceeding the way he did, but perhaps that is because he was so well grounded prior to entering medicine.
Morley’s early days, as for many others in Winnipeg were spent in the north end of the city, from 1942-1954, after which time Morley’s family moved south to 150 Waverley Street, which is where Morley’s brother Walter and sister Dorie grew up. Morley was a graduate of Queenston School, Robert H. Smith and later Kelvin High School. He continued at the University of Manitoba in the Honours Chemistry Programme that likely was the foundation of his success in the sciences.
But, he was also well rounded as he participated in the University Glee Club producing Broadway musicals ( I can vouch for that fact as he was with me in “Guys and Dolls”), also rowing with the Winnipeg Rowing Club. The result of Morley’s accomplishments, even in those early days, was recognized with his being awarded a Rhodes Scholarship, given for excellence in academia and outside interests.
It was then that the true depth of the Hollenberg medical talent started to emerge. From 1964-1968 Morley was at Oxford University in the Department of Pharmacology, working in the area of molecular pharmacology. He ended up with a Ph.D from Oxford. From there he went with his wife – the love of his life, Joan (née Omson), also of Winnipeg, to Baltimore, to attend Johns Hopkins Medical School.
Morley remained there for 11 years, from 1968-1979, which is where he obtained his medical degree and did his internship along with further research training.
Clearly, Morley was successful at Johns Hopkins since, during his tenure there, he was both an Assistant Professor in the Department of Pharmacology and Experimental Therapeutics from 1973-1979 and an Investigator of the Howard Hughes Medical Institute at the Hopkins Department of Medicine from 1974-79. Some of his work there contributed in an integral way to the 1986 Nobel Prize won by Stanley Cohen of Vanderbilt University.
In 1979 Hollenberg accepted a position as Department Head at the University of Calgary to develop a new area of molecular pharmacology in the Department of Pharmacology and Therapeutics. The lab Morley was associated with thrived and became famous for research into the area of hormone action in inflammatory disease.
That headship lasted for 11 years, until 1989. During the period from 1979 right up until the present, a span of 44 years, Morley has, in addition to maintaining his research programme, provided mentorship and guidance for graduate trainees for their MSc and PhD degrees, as well as for the younger faculty in their career development.
From 1980 right to the present, Morley has led a nationally funded research program investigating inflammatory disease and the training of undergraduates in that area.
Moreover, from 1999- 2022, it was Hollenberg who was the driving force behind the combined MD-PhD-MSc Leaders in Medicine program at the University of Calgary, from which many graduates have now assumed faculty positions in the Faculty of Medicine in Calgary.
Even with all the illustrious careers of so many Hollenberg doctors, Morley Hollenberg has truly achieved a tremendous level of accomplishment.
With all of that, there is yet another side to Dr. Morley Hollenberg, one that you would not expect. It became almost an alternative career: art. What began at age 10 under the guidance of a New York aunt, Morley rediscovered with a passion in Calgary and, in 1985, with the help of Master Chin Shek Lam and a close friend, Jack Wise, Morley began creating free-form Chinese brush calligraphy which, on the surface, would seem to be quite a distance from pharmacology.
As Morley puts it, “This art form represents for me an ideal medium for the visual expression of Nature’s secrets.” More significantly, in a way that links Morley’s work with his artistic passion, Morley says that “The brush strokes record visual images coming from the natural environment that surrounds us and from the microscopic world that is the subject of my scientific world.”
The result is that, even today, Morley continues both to conduct research at the University of Calgary Faculty of Medicine and, at the same time, to work as an artist in his home studio. As Morley reflects on the main areas of activity in his life, aside from Joan and his two children, son Daniel Hollenberg (who resides in Winnipeg) and his daughter Elisa, of Toronto (not to forget the grandchildren in Daniel’s family, Mira and Isaac, now in Winnipeg), he says: “ I have begun a series of Mandala paintings, inspired by the images of the cells expressing the dually-tagged receptors that are the focus of my research.” And, he adds, “ The mandalas I paint reflect the cell images and match the photographs I take wherein mandala images appear. I find there is a common source of creativity both in the doing of science and the creation of visual art.”
Not many of us (Are there any?) can take our professional work and merge it with another passion to create a combination of two worlds. I suspect none of the previous Hollenberg medical stars ever reached the Morley Hollenberg level of success in both the sciences and the arts. Morley is grateful for it all.

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.
