Introducing Centers of Progress: 40 Cities That Changed the World

“Cities, the dense agglomerations that dot the globe, have been engines of innovation since Plato and Socrates bickered in an Athenian marketplace,” as urban economist Edward Glaeser explains in his book The Triumph of the City.

Athens’s storied breakthroughs in philosophy are but one example of how cities have often been the sites of pivotal advances throughout history. Kyoto gave us the novel. Bologna gave us the university. Florence gave us the Renaissance. Paris gave us the Enlightenment. Manchester gave us the Industrial Revolution. Los Angeles gave us cinema. Postwar New York gave us modern finance . . . the list goes on. As Glaeser also notes, “Wandering these cities—whether down cobblestone sidewalks or grid-cutting cross streets, around roundabouts or under freeways—is to study nothing less than human progress.”

If you’re not able to travel to each of these extraordinary cities, perhaps the next best thing is to embark on a virtual tour from the comfort of your home. To that end, I wrote a book surveying 40 of history’s greatest urban centers, showcasing each city at a moment in time when it notably contributed to progress.

Centers of Progress: 40 Cities That Changed the World offers a fact-filled yet accessible crash course in global urban history, spanning from the agricultural revolution to the digital revolution. This book affirms the importance of cities to the story of human progress and innovation by shining a spotlight on some of the places that have helped create the modern world.

The book’s chapters can guide you through the Library of Alexandria, the stock exchange of Dutch Golden Age-era Amsterdam, and the pubs of Edinburgh during the Scottish Enlightenment, all in an afternoon.

Centers of Progress “takes the reader on a time-travel cruise through the great flash points of human activity to catch innovations that have transformed human lives” at their moment of invention, according to writer Matt Ridley in the insightful foreword that he kindly provided. Come explore Agra as the Taj Mahal was erected and Cambridge as Isaac Newton penned the Principia. Meet engineers in Ancient Rome, Silk Road merchants in Tang Dynasty Chang’an, music composers in 19th-century Vienna, and Space Age flight controllers in Houston.

Learning about past achievements may even hold the secret to fostering innovation in the present.

As I note in the book, “Although there are some exceptions, most cities reach their creative peak during periods of peace. Most centers of progress also thrive during times of relative social, intellectual, and economic freedom, as well as openness to intercultural exchange and trade. And centers of progress tend to be highly populated. . . . Identifying those common denominators among the places that have produced history’s greatest achievements is one way to learn what causes progress in the first place. After all, change is a constant, but progress is not.”

From the fall of the Berlin Wall to Hong Kong’s transformation from a war-ravaged “barren island” into a prosperous metropolis, many of the stories featured in Centers of Progress hold valuable lessons about the importance of ideas, people, and freedom. I hope that you will consider joining me on a journey through the book’s pages to some of history’s greatest centers of progress.

Breastfeeding Device Measures Babies’ Milk Intake in Real Time

“While breastfeeding has many benefits for a parent and their baby, it has one major drawback: It’s incredibly difficult to know how much milk the baby is consuming.

To take the guesswork out of breastfeeding, an interdisciplinary team of engineers, neonatologists and pediatricians at Northwestern University has developed a new wearable device that can provide clinical-grade, continuous monitoring of breast milk consumption.

The unobtrusive device softly and comfortably wraps around the breast of a nursing parent during breastfeeding and wirelessly transmits data to a smartphone or tablet. Parents can then view a live graphical display of how much milk their baby has consumed in real time.

By eliminating uncertainty, the device can provide peace of mind for parents during their baby’s first days and weeks. In particular, the new technology could help reduce parental anxiety and improve clinical management of nutrition for vulnerable babies in the neonatal intensive care unit.”

World-First Gonorrhoea Vaccine Launched by NHS England

“England will be the first country in the world to start vaccinating people against the sexually transmitted infection gonorrhoea.

It will not be available for everyone. The focus will mainly be on gay and bisexual men with a history of multiple sexual partners or an STI.

The vaccine is 30-40% effective, but NHS England hopes it will reverse soaring numbers of infections.

There were more than 85,000 cases in 2023 – the highest since records began in 1918.”

Psychedelic Nasal Spray Shows Promise Against Depression

“A psychedelic nasal spray requiring a much shorter period of clinical supervision has shown promise against treatment-resistant depression, giving biotechs hope that this type of drug will become a viable option for healthcare systems to use for mental health conditions. 

Atai Life Sciences and Beckley Psytech announced on Tuesday that patients in their trial of mebufotenin benzoate — based on a compound found in many plants and the venom of the Colorado River toad — demonstrated ‘clinically meaningful’ reductions in depressive symptoms as soon as the day after treatment.

The effect of a single treatment lasted for the trial of eight weeks without plateauing by the end and there were no serious side effects.

The trial of 193 patients in six countries found that the majority were ready for discharge 90 minutes after the dose, a marked improvement from previous trials of psychedelic treatments, where patients required supervision for a whole day.”

Gut Microbes Could Protect Us from Toxic “Forever Chemicals”

“Scientists at the University of Cambridge have identified a family of bacterial species, found naturally in the human gut, that absorb various PFAS molecules from their surroundings.  When nine of these bacterial species were introduced into the guts of mice to ‘humanise’ the mouse microbiome, the bacteria rapidly accumulated PFAS eaten by the mice – which were then excreted in faeces.

The researchers also found that as the mice were exposed to increasing levels of PFAS, the microbes worked harder, consistently removing the same percentage of the toxic chemicals. Within minutes of exposure, the bacterial species tested soaked up between 25% and 74% of the PFAS.

The results are the first evidence that our gut microbiome could play a helpful role in removing toxic PFAS chemicals from our body – although this has not yet been directly tested in humans.

The researchers plan to use their discovery to create probiotic dietary supplements that boost the levels of these helpful microbes in our gut, to protect against the toxic effects of PFAS.”
