What are microplastics, anyway?

Microplastics are defined as tiny plastic particles that measure less than 5 millimeters in size. These minuscule fragments originate from various sources, which include the breakdown of larger plastic items that have been discarded, microbeads found in personal care products like exfoliating scrubs, synthetic fibers that shed from clothing during washing and even tire particles that are released from vehicles and washed into storm drains. Once in our waterways, these tiny plastics can eventually make their way into our drinking water, posing a hidden threat to our health.

How much plastic are we actually drinking?

Research has shown that microplastics can be found in both tap water and bottled water, with concentrations varying widely depending on the source. Studies indicate that microplastic levels in bottled water tend to be higher than those found in tap water. Concentrations can range from a mere 0.0001 particles per liter to a staggering 930 particles per liter in tap water. These findings raise alarming questions about the safety of the water we consume daily, as reusable plastic bottles may release even more microplastics than single-use bottles.

Should we be worried?

The health implications of ingesting microplastics are still being studied, and while there is limited evidence of direct harm from the particles themselves, there are growing concerns about the chemicals and additives that are often found in plastics.

Additionally, harmful microbes may hitch a ride on these tiny particles, further complicating the issue. Experts are particularly worried about the potential for these particles to accumulate in our bodies over time, leading to unknown long-term health effects.

THE TROUBLING TRUTH ABOUT OUR COUNTRY’S RECYCLING PROGRAMS 

A breakthrough in microplastic detection

Until recently, detecting microplastics in water samples required expensive lab equipment and trained technicians. However, researchers at the University of British Columbia (UBC) have developed a game-changing tool to address this issue. Dr. Tianxi Yang and his team have created a small, portable device that can accurately measure microplastics in water samples within minutes.

The innovative tool consists of a 3D-printed box containing a wireless digital microscope, a green LED and an excitation filter. It works in conjunction with a smartphone app that uses machine learning to analyze images from the microscope. The device requires only a tiny amount of water — less than a drop — mixed with a special solution that makes microplastics fluoresce under green light.

In tests using disposable polystyrene cups, the UBC team found that each cup released “hundreds of millions” of nano-sized particles into just 50 milliliters of water. This discovery highlights the prevalence of microplastics in everyday items and the potential for significant exposure through drinking water.

Implications for public health

The development of this low-cost, portable tool could revolutionize our understanding of microplastic pollution in drinking water. It allows for quick, cheap detection of plastic particles ranging from 50 nanometers to 10 microns in size — particles too small to be seen by the naked eye.

Dr. Yang emphasizes the significance of this breakthrough:

“The breakdown of larger plastic pieces into microplastics and nanoplastics presents significant threats to food systems, ecosystems and human health. This new technique allows quick, cheap detection of these plastics, which could help protect our health and ecosystems.”

What can we do?

While research on the health impacts of ingesting microplastics is ongoing, there are steps we can take to reduce our exposure. One effective measure is to consider using a water filter designed to remove microplastics. Additionally, opting for tap water over bottled water whenever possible can significantly decrease your plastic consumption. It is also important to reduce your use of single-use plastics in everyday life, as this will help decrease overall plastic pollution in our environment. Dr. Yang also emphasizes the importance of developing biodegradable packaging materials to replace traditional plastics, moving toward a more sustainable world.

Here’s your first look at Kratos in Amazon’s God of War show

Amazon has slowly been teasing out casting details for its live-action adaptation of God of War, and now we have our first look at the show. It’s a single image but a notable one showing protagonist Kratos and his son Atreus. The characters are played by Ryan Hurst and Callum Vinson, respectively, and they look relatively close to their video game counterparts.

There aren’t a lot of other details about the show just yet, but this is Amazon’s official description:

The God of War series storyline follows father and son Kratos and Atreus as they embark on a journey to spread the ashes of their wife and mother, Faye. Through their adventures, Kratos tries to teach his son to be a better god, while Atreus tries to teach his father how to be a better human.

That sounds a lot like the recent soft reboot of the franchise, which started with 2018’s God of War and continued through Ragnarök in 2022. For the Amazon series, Ronald D. Moore, best-known for his work on For All Mankind and Battlestar Galactica, will serve as showrunner. The rest of the cast includes: Mandy Patinkin (Odin), Ed Skrein (Baldur), Max Parker (Heimdall), Ólafur Darri Ólafsson (Thor), Teresa Palmer (Sif), Alastair Duncan (Mimir), Jeff Gulka (Sindri), and Danny Woodburn (Brok).

While production is underway on the God of War series, there’s no word on when it might start streaming.

What you need to know about fake AI extensions

Security researchers at browser security company LayerX discovered a large campaign involving 30 malicious Chrome extensions disguised as AI-powered assistants (via BleepingComputer). Together, these extensions were installed more than 300,000 times by unsuspecting users.

Some of the most popular extensions included names like AI Sidebar with 70,000 users, AI Assistant with 60,000 users, ChatGPT Translate with 30,000 users, and Google Gemini with 10,000 users. Another extension called Gemini AI Sidebar had 80,000 users before it was removed.

These extensions were distributed through the official Chrome Web Store, which made them appear legitimate and trustworthy. Even more concerning, researchers found that many of these extensions were connected to the same malicious server, showing they were part of a coordinated effort.

While some extensions have since been removed, others remain available. This means new users could still unknowingly install them and expose their personal data. Here’s the list of the affected extensions:

How the fake AI Chrome extension attack works

These fake extensions pretend to offer helpful AI features, such as translating text, summarizing emails, or acting as an AI assistant. But behind the scenes, they quietly monitor what you are doing online.

Once installed, the extension gains permission to view and interact with the websites you visit. This allows it to read the contents of web pages, including login screens where you enter your username and password.

In some cases, the extensions specifically targeted Gmail. They could read your email messages directly from your browser, including emails you received and even drafts you were still writing. This means attackers could access private conversations, financial information and sensitive personal details.

The extensions then sent this information to servers controlled by the attackers. Because they loaded content remotely, the attackers could change their behavior at any time without needing to update the extension.

Some versions could also activate voice features through your browser. This could potentially capture spoken conversations near your device and send transcripts back to the attackers.

If you installed one of these extensions, attackers may already have access to extremely sensitive information. This includes your email content, login credentials, browsing habits and possibly even voice recordings.

We reached out to Google for comment, and a spokesperson told CyberGuy that the company “can confirm that the extensions from this report have all been removed from the Google Web Store.”

7 ways you can protect yourself from malicious Chrome extensions

If you have ever installed an AI-related Chrome extension, taking a few simple precautions now can help protect your accounts and prevent further damage.

Advertisement

1) Remove any suspicious or unused browser extensions

On a Windows PC or Mac, open Chrome and type chrome://extensions into the address bar. Review every extension listed. If you see anything unfamiliar, especially AI assistants you don’t remember installing, click “Remove” immediately. Malicious extensions depend on going unnoticed. Removing them stops further data collection and cuts off the attacker’s access to your information.

2) Change your passwords

If you installed any suspicious extension, assume your passwords may be compromised. Start by changing your email password first, since email controls access to most other accounts. Then update passwords for banking, shopping and social media accounts. This prevents attackers from using stolen credentials to break into your accounts.

3) Use a password manager to create and protect strong passwords

A password manager generates unique, complex passwords for each account and stores them securely. This prevents attackers from accessing multiple accounts if one password is stolen. Password managers also alert you if your login credentials appear in known data breaches, helping you respond quickly and protect your identity. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

4) Install strong antivirus software and keep it active

Good antivirus software can detect malicious browser extensions, spyware, and other hidden threats. It scans your system for suspicious activity and blocks harmful programs before they can steal your information. This adds an important layer of protection that works continuously in the background to keep your device safe. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com.

5) Use an identity theft protection service

Identity theft protection services monitor your personal data, including email addresses, financial accounts, and Social Security numbers, for signs of misuse. If criminals try to open accounts or commit fraud using your information, you receive alerts quickly. Early detection allows you to act fast and limit financial and personal damage. See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com.

6) Keep your browser and computer fully updated

Software updates fix security vulnerabilities that attackers exploit. Enable automatic updates for Chrome and your operating system so you always have the latest protections. These updates strengthen your defenses against malicious extensions and prevent attackers from taking advantage of known weaknesses.

7) Use a personal data removal service

Personal data removal services scan data broker websites that collect and sell your personal information. They help remove your data from these sites, reducing what attackers can find and use against you. Less exposed information means fewer opportunities for criminals to target you with scams, identity theft or phishing attacks.

Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.

Kurt’s key takeaway

Even tools designed to make your life easier can become tools for cybercriminals. Malicious extensions often hide behind trusted names and convincing features, making them difficult to spot. You can significantly reduce your risk by reviewing your browser extensions regularly, removing anything suspicious and using protective tools like password managers and strong antivirus software.

Anthropic refuses Pentagon’s new terms, standing firm on lethal autonomous weapons and mass surveillance

Anthropic refuses Pentagon’s new terms, standing firm on lethal autonomous weapons and mass surveillance

Less than 24 hours before the deadline in an ultimatum issued by the Pentagon, Anthropic has refused the Department of Defense’s demands for unrestricted access to its AI.

It’s the culmination of a dramatic exchange of public statements, social media posts, and behind-the-scenes negotiations, coming down to Defense Secretary Pete Hegseth’s desire to renegotiate all AI labs’ current contracts with the military. But Anthropic, so far, has refused to back down from its two current red lines: no mass surveillance of Americans, and no lethal autonomous weapons (or weapons with license to kill targets with no human oversight whatsoever). OpenAI and xAI had reportedly already agreed to the new terms, while Anthropic’s refusal had led to CEO Dario Amodei being summoned to the White House this week for a meeting with Hegseth himself, in which the Secretary reportedly issued an ultimatum to the CEO to back down by the end of business day on Friday or else.

In a statement late Thursday, Amodei wrote, “I believe deeply in the existential importance of using AI to defend the United States and other democracies, and to defeat our autocratic adversaries. Anthropic has therefore worked proactively to deploy our models to the Department of War and the intelligence community.”

He added that the company has “never raised objections to particular military operations nor attempted to limit use of our technology in an ad hoc manner” but that in a “narrow set of cases, we believe AI can undermine, rather than defend, democratic values” — going on to specifically mention mass domestic surveillance and fully autonomous weapons. (Amodei mentioned that “partial autonomous weapons … are vital to the defense of democracy” and that fully autonomous weapons may eventually “prove critical for our national defense,” but that “today, frontier AI systems are simply not reliable enough to power fully autonomous weapons.” He did not rule out Anthropic acquiescing to the military’s use of fully autonomous weapons in the future but mentioned that they were not ready now.)

The Pentagon had already reportedly asked major defense contractors to assess their dependence on Anthropic’s Claude, which could be seen as the first step to designating the company a “supply chain risk” – a public threat that the Pentagon had made recently (and a classification usually reserved for threats to national security). The Pentagon was also reportedly considering invoking the Defense Production Act to make Anthropic comply.

Amodei wrote in his statement that the Pentagon’s “threats do not change our position: we cannot in good conscience accede to their request.” He also wrote that “should the Department choose to offboard Anthropic, we will work to enable a smooth transition to another provider, avoiding any disruption to ongoing military planning, operations, or other critical missions. Our models will be available on the expansive terms we have proposed for as long as required.”
