Warshaw, George Washington University Following George Floyd’s death at the hands of police in Minneapolis in 2020, the U.S. has undergone a national reckoning over crime prevention and police reform. Across the country, calls went out from activists to rethink the scope and role of the police. Some on the left vowed to “defund” the police. Others on the right promised to instead “back the blue” and maintain or increase police funding. This rhetorical tug-of-war unfolded while many cities across the country grappled with spiking crime rates during the first months of the COVID-19 pandemic. Blaming crime on Democratic city leaders was a centerpiece of Donald Trump’s 2024 presidential campaign. He repeatedly made claims about crime spikes in recent years without evidence or context. More recently, Republican congressional leaders have called several Democratic mayors from across the country to testify before Congress about their sanctuary city policies that are aimed at protecting noncitizens from deportation. These congressional politicians have asserted that these Democratic mayors – Brandon Johnson of Chicago, Mike Johnston of Denver, Michelle Wu of Boston, and Eric Adams of New York – have “created a public safety nightmare” in their cities by allowing immigrants without legal authorization to stay there. Journalists and politicians on both sides of the aisle have claimed that local election results over the past four years in places like San Francisco and Los Angeles reflect a widespread frustration with Democratic policies on crime in cities. Under this argument, Democratic city leaders need to change their approach on crime to satisfy voters. It’s become a political axiom of sorts that policies championed largely by Democratic city leaders over the past half decade have resulted in rising crime levels. As researchers of politics and public policy, we wanted to figure out if that was true.A New York Times headline from June 8, 2022, linking crime rates and the Democratic Party.The New York Times
Neither party does a better job
As any student of introductory statistics learns, correlation doesn’t imply causation. Looking at increases or decreases in crime rates in Republican or Democratic cities and claiming either party is to blame would be making exactly this error: confusing correlation with causation. We put to the test the argument that one side or the other is better at fighting crime in our research published in January 2025. By employing three decades of data on mayoral elections from across the country, we were able to disentangle city leaders’ partisanship from other features of cities. Contrary to much of the political rhetoric and media coverage aimed at most Americans, our results show that neither party is doing a better job at actually causing crime to decrease. In Dallas, Mayor Eric Johnson has claimed that Democratic leaders aren’t taking public safety seriously and that the Democratic Party is “with the criminals.” Johnson switched from being a Democrat to a Republican in 2023 and attributes his decision at least partially to this partisan difference on crime and policing and the seriousness with which he takes this policy issue. But our research shows that Johnson’s and others’ claims about Democratic cities becoming more dangerous just aren’t true: Mayors from the Democratic Party aren’t making cities any more – or less – dangerous than mayors from the Republican Party. Nor, it turns out, is there any support for claims by some progressive Democrats that they would reduce the role – and enormous budgets – of police departments in cities across the country. When we examined the number of sworn police officers in cities and how much money those cities spend on the police, Democratic and Republican mayors alike have had surprisingly little influence on police department budgets or sizes. In other words, Democrats aren’t cutting police budgets, nor are Republicans increasing police budgets. Most cities have increased police budgets in the past few years, possibly due to pressure from police unions.Dallas Mayor Eric Johnson speaks during the second day of the 2024 Republican National Convention in Milwaukee on July 16, 2024.Andrew Caballero-Reynolds/AFP via Getty Images
‘Crime is nonpartisan’
It turns out that campaign promises from both sides of the partisan aisle about crime and policing have little bearing on what’s happening on the ground in most cities and police departments across the country. Neither party is doing a better job at reducing crime. Nor is either party actually addressing the ballooning financial cost of local police forces in the U.S., nor the long-term reputational costs from police misconduct for trust in the police and government more broadly. As others have said: crime is nonpartisan. Crime has decreased across the U.S. during the past three decades overall, and the isolated cities where crime has increased recently can reverse these temporary trends. Partisan blame narratives do little to actually lower crime and make neighborhoods safer, though. There are real evidence-backed policies that reduce crime – such as youth jobs programs in Chicago and Boston. Other policies reduce racial disparities in the criminal justice system – such as alternative 911 response programs that use unarmed behavioral health workers to respond to some types of emergencies. These policies and interventions might not be as slogan-worthy as “defund the police” or “back the blue.” Nor is implementing these policies as politically convenient as blaming sanctuary city mayors. But research shows that they work and can move cities toward the shared goal of improved public safety for their residents.Justin de Benedictis-Kessner, Associate Professor of Public Policy, Harvard Kennedy School and Christopher S.

How Water Towers Work: The Simple System That Keeps Water Flowing in American Cities
Learn how water towers work in the United States, why they are so tall, and how gravity helps cities maintain water pressure and emergency water supplies.
Water towers are one of the most recognizable pieces of infrastructure across the United States. Rising above towns, suburbs, and cities, these elevated tanks quietly perform a vital function every day: maintaining water pressure and storing emergency water for local communities.
Although they may look simple, water towers are an essential part of modern municipal water systems and remain one of the most reliable ways to deliver water to homes and businesses.
The Basic Science Behind Water Towers
Water towers work using a simple principle of physics: gravity.
Water from treatment plants or underground wells is pumped into a storage tank located high above the ground—typically between 100 and 200 feet tall. Because the tank is elevated, gravity naturally pushes the water downward through the city’s pipeline network.
This gravitational force creates the water pressure needed to supply homes, businesses, irrigation systems, and fire hydrants throughout the community.
Most residential plumbing systems in the United States operate best at 40 to 60 PSI (pounds per square inch), which water towers can easily provide through elevation alone.
Ever wondered why cities build giant water towers? 💧 It’s all about gravity. Water is pumped up into the tower and gravity pushes it through city pipes, creating the pressure that delivers water to homes, businesses, and fire hydrants. Simple engineering that keeps entire towns running. Now you know. Hashtags NowYouKnow WaterTower Infrastructure EngineeringExplained HowItWorks DidYouKnow CityInfrastructure UrbanEngineering STMDailyNews EducationalContent ♬ original sound – STMDailyNews – STMDailyNews
Why Water Towers Are Built So Tall
The height of a water tower determines how much pressure it can create. Engineers use a common rule:
For example, a water tower standing 120 feet tall can generate roughly 50 PSI of pressure—perfect for delivering water throughout a residential neighborhood.
Why Cities Still Use Water Towers
While modern pumping systems could theoretically move water through pipes continuously, water towers provide several major advantages that make them a preferred design in many municipal systems.
Stable Water Pressure – Water towers maintain consistent pressure even during peak usage times.
Energy Efficiency – Pumps can refill towers overnight when electricity demand is lower.
Emergency Water Supply – If power fails, gravity can continue delivering water.
Fire Protection – Fire hydrants depend on strong, immediate water pressure.
The Daily Fill-and-Use Cycle
Water towers typically operate on a daily cycle based on community demand.
Night: Pumps refill the tower while water demand is low.
Morning: Water levels drop as residents shower and prepare for the day.
Daytime: Businesses and homes continue drawing water from the tower.
Evening: The system begins refilling the tank for the next day.
How Much Water Can a Tower Store?
Water towers come in many sizes depending on the population they serve.
Small towns: 50,000–300,000 gallons
Suburban communities: 500,000–1 million gallons
Larger urban systems: up to 2 million gallons or more
Even a single tower holding one million gallons can supply thousands of homes for several hours during peak demand or emergencies.
Modern Technology Inside Water Towers
Today’s water towers are equipped with advanced monitoring systems that help utilities maintain safe and reliable water supplies.

Landmarks in the American Skyline
Many cities turn their water towers into local landmarks by painting them with city names, mascots, or community slogans. Some towns even design towers shaped like giant objects such as fruit, coffee cups, or sports balls.
Despite their distinctive appearance, water towers remain one of the simplest and most reliable engineering solutions for delivering clean water to millions of Americans every day.
Next time you see a water tower rising above a town skyline, remember: it’s not just a landmark—it’s the gravity-powered system that keeps water flowing.

The Unfavorable Semicircle Mystery: The YouTube Channel That Uploaded Tens of Thousands of Cryptic Videos
In 2015, the YouTube channel Unfavorable Semicircle gained attention for its enigmatic and abundant video uploads, totaling over 70,000 before its deletion in 2016. Theories about its purpose vary, from automated content generation to digital art experimentation, leaving its intent unresolved.
In the vast digital landscape of the internet, strange phenomena occasionally emerge that leave investigators, tech enthusiasts, and everyday viewers scratching their heads. One of the most puzzling cases appeared in 2015, when a mysterious YouTube channel called Unfavorable Semicircle began uploading an astonishing number of cryptic videos.
Within months, the channel had published tens of thousands of bizarre clips, many of which seemed random, incomprehensible, and visually chaotic. But as internet detectives began analyzing the content more closely, they discovered that these videos might not have been random at all.
The Sudden Appearance of an Internet Mystery
The Unfavorable Semicircle channel reportedly appeared in March 2015, with its first uploads arriving in early April.
Almost immediately, the channel began publishing videos at an incredible pace. Observers estimated that the account uploaded thousands of videos per week, sometimes multiple videos per minute. By the time the channel disappeared in early 2016, researchers believed it had uploaded well over 70,000 videos, possibly far more.
The scale alone made the project seem impossible for a human to manage manually.
Most of the videos shared similar characteristics:
Extremely short or very long runtime
Abstract visuals such as flashing colors, static, or distorted imagery
Little or no audio, or heavily distorted sounds
Titles made of random characters, symbols, or numbers
To casual viewers, the videos looked like pure digital noise. However, online investigators suspected something more deliberate was happening.
Hidden Images Discovered
The mystery deepened when researchers began extracting individual frames from some videos.
When thousands of frames from certain clips were stitched together, the results sometimes formed coherent images. One of the most famous examples involved a video titled “LOCK.” While the footage appeared chaotic at first, combining the frames revealed a recognizable composite image.
This discovery suggested the videos were carefully constructed rather than random uploads.
Theories About the Channel’s Purpose
Because the creator never explained the project, several theories emerged across Reddit, YouTube, and internet forums.
Automated Experiment Many believe the channel was created using automated software that generated and uploaded content at scale.
Alternate Reality Game (ARG) Some viewers suspected the channel might be part of a hidden puzzle or digital scavenger hunt.

Encrypted Communication Others compared the channel to Cold War “numbers stations,” suggesting the videos could contain coded messages.
Digital Art Project Another theory suggests the channel was an experimental art project exploring algorithms, data, and visual noise.
Despite years of investigation, no single explanation has been confirmed.
Why the Channel Disappeared
In February 2016, YouTube removed the channel, reportedly due to spam or automated activity violations.
By that time, the channel had already become a minor internet legend. Fortunately, some researchers managed to archive a large portion of the videos before they disappeared.
Even today, archived clips continue to circulate online as investigators attempt to decode them.
Unfavorable Semicircle: The Most Bizarre YouTube Mystery
Other Mysterious YouTube Channels
The Unfavorable Semicircle mystery is not the only strange case on YouTube.
One well-known example is Webdriver Torso, a channel that uploaded hundreds of thousands of videos showing red and blue rectangles with simple beeping sounds. Internet speculation ran wild before Google eventually confirmed it was an internal YouTube testing account.
Another example is AETBX, which posts distorted visuals and unusual audio that some viewers believe contain hidden patterns or encoded information.
These cases highlight how automation, experimentation, and creativity can sometimes blur the line between technology and mystery.

A Digital Mystery That Remains Unsolved
Nearly a decade later, the true purpose behind Unfavorable Semicircle remains unknown.
Was it a sophisticated experiment? A piece of algorithmic art? Or simply an automated test that accidentally captured the internet’s imagination?
Whatever the explanation, the channel stands as a reminder that even in a world filled with billions of videos and endless information, the internet can still produce mysteries that challenge our understanding of technology.
Why Internet Mysteries Still Fascinate Us
Stories like Unfavorable Semicircle capture attention because they combine technology, creativity, and the unknown. They invite people from around the world to collaborate, analyze patterns, and search for meaning hidden in the noise.
And sometimes, the most intriguing part of the mystery is that the answer may never fully be known.

International Women’s Day is celebrated globally on March 8th to honor women’s achievements and promote gender equality, originating from a 1908 march in New York for better rights.
International Women’s Day is a global celebration that honors the achievements of women and highlights the progress still to be made in the fight for gender equality. On this day, people around the world come together to recognize the amazing contributions of women everywhere and to rally for greater gender equity in all areas of life.
The origins of International Women’s Day can be traced back to 1908, when 15,000 women marched through the streets of New York City to demand better working conditions and the right to vote. Since then, the celebration has grown to be an international event, with more than 100 countries recognizing the day. The United Nations even declared March 8th as International Women’s Day in 1975, to honor the struggles of women around the world.
This year’s International Women’s Day theme is #ChooseToChallenge, meaning that everyone is encouraged to call out gender bias and inequality when they see it. We’re also encouraged to celebrate women’s achievements, support each other, and take action for equality.
It’s important to recognize the progress we’ve made in terms of gender equality, but we still have a long way to go. International Women’s Day serves as a reminder that we must continue to fight for gender equality in all areas of life. Let’s use this day to honor the contributions of women around the world, and to continue the fight for a more equitable world.
