🚦 Who Really Invented the Modern Traffic Light?

The modern traffic light, largely attributed to Garrett Morgan’s 1923 invention, introduced a critical yellow warning light that improved public safety. Despite his significant impact on traffic systems, Morgan’s contributions have often been overlooked due to historical racism.

Modern Traffic Light

 


When you think about the traffic light, you probably picture green for go, red for stop, and maybe a frustrated glance at the yellow. But have you ever stopped to ask: Who actually invented this system we take for granted every day?

The story of the modern traffic light isn’t just about technology—it’s about innovation, public safety, and a Black inventor named Garrett Morgan who changed the way we move through the world.


🔦 Early Traffic Signals: A Dangerous Beginning

Before cars dominated streets, early attempts at traffic control involved manual policing and hand signals. In 1868, the first gas-powered traffic signal was installed in London outside the British Houses of Parliament. Designed by J.P. Knight, a railway engineer, this early signal exploded after just a month due to a gas leak—killing a police officer and abandoning the idea for years.

As cars became more common in the early 20th century, so did traffic jams—and accidents. Cities needed a safer, more efficient solution.


🛠️ Enter Garrett Morgan

In 1923, Garrett Morgan, an African-American inventor and entrepreneur from Cleveland, Ohio, received U.S. Patent No. 1,475,024 for a traffic control device that added a crucial feature: a “warning position” between stop and go. This idea is the basis for today’s yellow light.

His signal was:

  • Manually operated
  • T-shaped
  • Designed to be mounted on a post
  • And included a buffer phase to clear intersections before switching direction

This innovation was not only about traffic flow—it was about safety and preventing collisions at a time when automobile fatalities were rapidly increasing.

Morgan sold the rights to his invention to General Electric for $40,000 (equivalent to over $700,000 today), though his contributions were overlooked for decades.

⚙️ Was Morgan the 

Only

 Inventor?

No. Traffic signal history has multiple contributors:

  • Lester Wire, a Salt Lake City policeman, created an electric traffic light prototype in 1912.
  • William Ghiglieri patented an automatic signal in 1917.
  • Garrett Morgan’s version stood out for its practical innovation—the transitional phase—and for being one of the first widely adopted and commercially viable versions.

In other words, Morgan helped move the traffic light from an experimental device to a nationwide safety standard.

✊ Why Garrett Morgan Deserves More Recognition

Garrett Morgan’s impact goes far beyond traffic lights. He also invented a gas mask used by firefighters and soldiers, and he launched one of the first Black-owned newspapers in the U.S.

He was a true innovator, working in an era where his contributions were often ignored due to racism. Today, we honor his legacy by telling his story and recognizing how his vision saved countless lives.

US Exit From the WHO: What America and the World Stand to Lose in Global Health Security

The U.S. officially withdrew from the WHO in January 2026, following claims of unfair funding practices and ineffective pandemic responses. This move threatens global health coordination, as the U.S. has historically been the largest funder. Experts warn of immediate impacts, including job cuts at WHO and difficulties in managing health crises like influenza.

US exit from the World Health Organization marks a new era in global health policy – here’s what the US, and world, will lose

The U.S. departure from the World Health Organization became official in late January 2026, according to the Trump administration – a year after President Donald Trump signed an executive order on inauguration day of his second term declaring that he was doing so. He first stated his intention to do so during his first term in 2020, early in the COVID-19 pandemic.

The U.S. severing its ties with the WHO will cause ripple effects that linger for years to come, with widespread implications for public health. The Conversation asked Jordan Miller, a public health professor at Arizona State University, to explain what the U.S. departure means in the short and long term.

Why is the US leaving the WHO?

The Trump administration says it’s unfair that the U.S. contributes more than other nations and cites this as the main reason for leaving. The White House’s official announcement gives the example of China, which – despite having a population three times the size of the U.S. – contributes 90% less than the U.S. does to the WHO.

The Trump administration has also claimed that the WHO’s response to the COVID-19 pandemic was botched and that it lacked accountability and transparency.

The WHO has pushed back on these claims, defending its pandemic response, which recommended masking and physical distancing.

The U.S. does provide a disproportionate amount of funding to the WHO. In 2023, for example, U.S. contributions almost tripled that of the European Commission’s and were roughly 50% more than the second highest donor, Germany. But health experts point out that preventing and responding quickly to public health challenges is far less expensive than dealing with those problems once they’ve taken root and spread.

However, the withdrawal process is complicated, despite the U.S. assertion that it is final. Most countries do not have the ability to withdraw, as that is the way the original agreement to join the WHO was designed. But the U.S. inserted a clause into its agreement with the WHO when it agreed to join, stipulating that the U.S. would have the ability to withdraw, as long as it provided a one-year notice and paid all remaining dues. Though the U.S. gave its notice when Trump took office a year ago, it still owes the WHO about US$260 million in fees for 2024-25. There are complicated questions of international law that remain. https://www.youtube.com/embed/uacD-03S28E?wmode=transparent&start=0 The U.S. has been a dominant force in the WHO, and its absence will have direct and lasting impacts on health systems in the U.S. and other countries.

What does US withdrawal from the WHO mean in the short term?

In short, the U.S. withdrawal weakens public health abroad and at home. The WHO’s priorities include stopping the spread of infectious diseases, stemming antimicrobial resistance, mitigating natural disasters, providing medication and health services to those who need it, and even preventing chronic diseases. So public health challenges, such as infectious diseases, have to be approached at scale because experience shows that coordination across borders is important for success.

The U.S. has been the largest single funder of the WHO, with contributions in the hundreds of millions of dollars annually over the past decade, so its withdrawal will have immediate operational impacts, limiting the WHO’s ability to continue established programs.

As a result of losing such a significant share of its funding, the WHO announced in a recent memo to staff that it plans to cut roughly 2,300 jobs – a quarter of its workforce – by summer 2026. It also plans to downsize 10 of its divisions to four.

In addition to a long history of funding, U.S. experts have worked closely with the WHO to address public health challenges. Successes stemming from this partnership include effectively responding to several Ebola outbreaks, addressing mpox around the world and the Marburg virus outbreak in Rwanda and Ethiopia. Both the Marburg and Ebola viruses have a 50% fatality rate, on average, so containing these diseases before they reached pandemic-level spread was critically important.

The Infectious Diseases Society of America issued a statement in January 2026 describing the move as “a shortsighted and misguided abandonment of our global health commitments,” noting that “global cooperation and communication are critical to keep our own citizens protected because germs do not respect borders.”

What are the longer-term impacts of US withdrawal?

By withdrawing from the WHO, the U.S. will no longer participate in the organization’s Global Influenza Surveillance and Response System, which has been in operation since 1952. This will seriously compromise the U.S.’s ability to plan and manufacture vaccines to match the predicted flu strains for each coming year.

Annual flu vaccines for the U.S. and globally are developed a year in advance using data that is collected around the world and then analyzed by an international team of experts to predict which strains are likely to be most widespread in the next year. The WHO convenes expert panels twice per year and then makes recommendations on which flu strains to include in each year’s vaccine manufacturing formulation.

While manufacturers will likely still be able to obtain information regarding the WHO’s conclusions, the U.S. will not contribute data in the same way, and American experts will no longer have a role in the process of data analysis. This could lead to problematic differences between WHO recommendations and those coming from U.S. authorities.

The Centers for Disease Control and Prevention estimates that each year in the U.S. millions of people get the flu, hundreds of thousands of Americans are hospitalized and tens of thousands die as a result of influenza. Diminishing the country’s ability to prepare in advance through flu shots will likely mean more hospitalizations and more deaths as a result of the flu.

This is just one example of many of how the U.S.’s departure will affect the country’s readiness to respond to disease threats.

Additionally, the reputational damage done by the U.S. departure cannot be overstated. The U.S. has developed its position as an international leader in public health over many decades as the largest developer and implementer of global health programs.

I believe surrendering this position will diminish the United States’ ability to influence public health strategies internationally, and that is important because global health affects health in the U.S. It will also make it harder to shape a multinational response in the event of another public health crisis like the COVID-19 pandemic.

Public health and policy experts predict that China will use this opportunity to strengthen its position and its global influence, stepping into the power vacuum the U.S. creates by withdrawing. China has pledged an additional US$500 million in support of the WHO over the next five years.

As a member of the WHO, the United States has had ready access to a vast amount of data collected by the WHO and its members. While most data the WHO obtains is ultimately made available to the public, member nations have greater access to detailed information about collection methods and gain access sooner, as new threats are emerging.

Delays in access to data could hamstring the country’s ability to respond in the event of the next infectious disease outbreak.

Could the US return under a new president?

In short, yes. The WHO has clearly signaled its desire to continue to engage with the U.S., saying it “regrets the U.S. decision to withdraw” and hopes the U.S. will reconsider its decision to leave.

In the meantime, individual states have the opportunity to participate. In late January, California announced it will join the WHO’s Global Outbreak Alert & Response Network, which is open to a broader array of participants than just WHO member nations. California was also a founding member of the West Coast Health Alliance, which now includes 14 U.S. states that have agreed to work together to address public health challenges.

California Gov. Gavin Newsom has also launched an initiative designed to improve public health infrastructure and build trust. He enlisted national public health leaders for this effort, including former Centers for Disease Control and Prevention leaders Susan Monarez and Deb Houry, as well as Katelyn Jetelina, who became well known as Your Local Epidemiologist during the COVID-19 pandemic.

I think we will continue to see innovative efforts like these emerging, as political and public health leaders work to fill the vacuum being created by the Trump administration’s disinvestment in public health.

How to avoid seeing disturbing video on social media and protect your peace of mind

How to avoid seeing disturbing video on social media and protect your peace of mind

When graphic videos like those of the recent shooting of a protester by federal agents in Minneapolis go viral, it can feel impossible to protect yourself from seeing things you did not consent to see. But there are steps you can take.

Social media platforms are designed to maximize engagement, not protect your peace of mind. The major platforms have also reduced their content moderation efforts over the past year or so. That means upsetting content can reach you even when you never chose to watch it.

You do not have to watch every piece of content that crosses your screen, however. Protecting your own mental state is not avoidance or denial. As a researcher who studies ways to counteract the negative effects of social media on mental health and well-being, I believe it’s a way of safeguarding the bandwidth you need to stay engaged, compassionate and effective.

Why this matters

Research shows that repeated exposure to violent or disturbing media can increase stress, heighten anxiety and contribute to feelings of helplessness. These effects are not just short-term. Over time, they erode the emotional resources you rely on to care for yourself and others.

Protecting your attention is a form of care. Liberating your attention from harmful content is not withdrawal. It is reclaiming your most powerful creative force: your consciousness.

Just as with food, not everything on the table is meant to be eaten. You wouldn’t eat something spoiled or toxic simply because it was served to you. In the same way, not every piece of media laid out in your feed deserves your attention. Choosing what to consume is a matter of health.

And while you can choose what you keep in your own kitchen cabinets, you often have less control over what shows up in your feeds. That is why it helps to take intentional steps to filter, block and set boundaries.

Practical steps you can take

Fortunately, there are straightforward ways to reduce your chances of being confronted with violent or disturbing videos. Here are four that I recommend:

  • Turn off autoplay or limit sensitive content. Note that these settings can vary depending on device, operating system and app version, and can change.

https://datawrapper.dwcdn.net/d1deR/2

  • Use keyword filters. Most platforms allow you to mute or block specific words, phrases or hashtags. This reduces the chance that graphic or violent content slips into your feed.
  • Curate your feed. Unfollow accounts that regularly share disturbing images. Follow accounts that bring you knowledge, connection or joy instead.
  • Set boundaries. Reserve phone-free time during meals or before bed. Research shows that intentional breaks reduce stress and improve well-being.

Reclaim your agency

Social media is not neutral. Its algorithms are engineered to hold your attention, even when that means amplifying harmful or sensational material. Watching passively only serves the interests of the social media companies. Choosing to protect your attention is a way to reclaim your agency.

The urge to follow along in real time can be strong, especially during crises. But choosing not to watch every disturbing image is not neglect; it is self-preservation. Looking away protects your ability to act with purpose. When your attention is hijacked, your energy goes into shock and outrage. When your attention is steady, you can choose where to invest it.

You are not powerless. Every boundary you set – whether it is turning off autoplay, filtering content or curating your feed – is a way of taking control over what enters your mind. These actions are the foundation for being able to connect with others, help people and work for meaningful change.

More resources

I’m the executive director of the Post-Internet Project, a nonprofit dedicated to helping people navigate the psychological and social challenges of life online. With my team, I designed the evidence-backed PRISM intervention to help people manage their social media use.

Our research-based program emphasizes agency, intention and values alignment as the keys to developing healthier patterns of media consumption. You can try the PRISM process for yourself with an online class I launched through Coursera in October 2025. You can find the course, Values Aligned Media Consumption, on Coursera. The course is aimed at anyone 18 and over, and the videos are free to watch.

CES 2026 (Jan. 6–9 in Las Vegas) didn’t feel like a “future tech” show as much as a “right now” show. The big shift: AI wasn’t treated like a standalone product category anymore. It was the invisible layer powering everything from streaming discovery to robots that can actually do work.

For STM Daily News readers who live in the overlap of Entertainment and Tech, here are the exhibitors and trends that stood out most—plus why they matter beyond the show floor.

1) Sony Honda Mobility (AFEELA): The car as a rolling entertainment platform

Sony Honda Mobility’s AFEELA presence reinforced a direction CES keeps leaning into: the next generation of vehicles is competing as much on software and in-cabin experience as it is on horsepower.

What made it stand out:

  • AFEELA represents the “car as a connected device” idea taken seriously—where the cabin becomes a screen-first, service-driven environment.
  • It’s a clean example of how mobility and entertainment are merging: navigation, safety, personalization, and media all living in one interface.

2) Netflix + Amazon Prime Video + Roku + Xumo: Streaming is evolving into ecosystems

CES 2026’s Content & Entertainment story wasn’t about “who has the most subscribers.” It was about streaming as an ecosystem: bundling, ad-supported growth, and smarter discovery.

What made it stand out:

  • CES highlighted how streaming platforms are pushing beyond simple libraries into bundles, premium originals, and integrated experiences.
  • FAST (free ad-supported streaming TV) continues to gain traction, and device/platform players are positioning themselves as the front door.

3) Dolby: The quiet power behind the best-looking, best-sounding experiences

Dolby isn’t always the flashiest booth, but it consistently shows up as the tech that makes everything else feel “premium.”

What made it stand out:

  • In a year where screens, XR, and immersive venues are everywhere, audio and imaging standards are the difference between “cool demo” and “wow.”
  • Dolby’s relevance keeps growing as entertainment moves across phones, living rooms, cars, and wearables.

4) Meta + XREAL: Smart glasses keep inching toward mainstream

Wearables at CES 2026 weren’t just about steps and sleep. The momentum was in smart glasses and AR—especially as generative AI voice interfaces make hands-free use feel more natural.

What made it stand out:

  • CES noted smart/AR glasses evolving with features like real-time translation, recording, and AI voice interfaces.
  • For entertainment fans, this is where “watching” and “doing” start to blend—live overlays, creator tools, and new ways to capture experiences.

5) Samsung + LG + TCL: Screens are still the show’s main stage

Even in an AI-everywhere year, CES still belongs to display tech. Big brands kept proving that TVs aren’t just TVs—they’re hubs for gaming, streaming, smart home control, and ambient experiences.

What made it stand out:

  • Display leaders continue to set the tone for how entertainment is consumed at home.
  • The conversation is shifting from specs to experience: personalization, AI-powered recommendations, and multi-device continuity.

6) NVIDIA + AMD + Lenovo: The “AI PC” era is no longer theoretical

CES 2026 made it clear that the next wave of consumer computing is built around on-device AI. That matters for creators, editors, and anyone who lives in content.

What made it stand out:

  • CES highlighted AI’s move from “digital transformation” to “intelligent transformation,” including edge/enterprise and physical AI in robotics.
  • AMD’s CES keynote emphasized AI across devices from PCs to data centers, underscoring how quickly this is becoming standard.

7) Unitree + Richtech Robotics + Hyundai: Robots were the surprise crowd-pleaser

If CES 2026 had a “you had to see it” category, it was robotics. Not just novelty bots—machines built for real environments.

What made it stand out:

  • CES framed robotics as “physical AI,” where generative AI and simulation training help robots learn faster than traditional programming.
  • Humanoid robots, in particular, are moving from single-task demos toward more collaborative assistant roles.

The big takeaway for STM Daily News readers

CES 2026 wasn’t about one killer gadget. It was about convergence:

  • Entertainment is becoming more interactive, more personalized, and more portable.
  • Cars are becoming screens.
  • Wearables are becoming interfaces.
  • Robots are becoming the next “device category” people actually want to watch.

And underneath it all: AI is becoming less of a headline and more of the operating system for modern life.

Here’s a list of what stood out to us at CES 2026:
