Researchers explored how caffeine can quietly reduce the power of some antibiotics by changing how bacteria let them in

September 11, 2025

• Everyday substances, including caffeine, can trigger changes in bacteria like E. coli that make antibiotics less effective.

• Caffeine activates a regulatory path involving a bacterial protein called Rob, leading to less porin channels, which antibiotics use to enter the cell.

• The weakening effect depends on the antibiotic, the bacterial species, and specific genes; in Salmonella, for example, caffeine didnt reduce antibiotic effectiveness the same way.

We all know caffeine wakes us up, but what if that same caffeine could interfere with antibiotics we need?

A new study from researchers in Germany has found that caffeine (and other common chemicals) can affect how bacteria respond to certain antibiotics.

The kicker: its not because caffeine kills bacteria or is antibacterial itself, but because it alters the way bacteria regulate what they let in and push out. In some cases, that can make antibiotics less able to do their job.

Our data show that several substances can subtly but systematically influence gene regulation in bacteria, researcher Christoph Binsfeld, said in a news release.

The study

To figure out how everyday substances might change the way bacteria react to antibiotics, researchers ran a kind of stress test on E. coli, a common gut bacterium.

They exposed the bacteria to 94 different chemicals including antibiotics, prescription drugs, and food-related compounds like caffeine and watched how the bacteria responded.

Instead of just looking to see whether the bacteria grew or died, the team zoomed in on the gates and pumps in the bacterial cell wall. These are the entry and exit points that antibiotics use to get inside or get pushed back out. By using a glowing marker system, the scientists could track whether these gates opened wider, closed tighter, or stayed the same when exposed to each chemical.

They also tested slightly altered versions of E. coli that were missing certain control switches. This helped them pin down exactly which internal regulators were responsible for the bacterias reactions.

The results

Caffeine stood out as one of the surprising players. On its own, caffeine didnt harm the bacteria. But when it was present, it flipped on a genetic switch that told the bacteria to close some of its entry gates specifically a channel called OmpF, which many antibiotics rely on to slip inside.

With fewer gates open, antibiotics like amoxicillin and ciprofloxacin couldnt get in as easily. That meant it took higher doses of those antibiotics to slow the bacteria down. In fact, in some tests, E. coli became up to 40% harder to stop when caffeine was added.

The effect wasnt universal, though. It depended on the specific bacteria and the drug. For instance, when the same tests were run on Salmonella, caffeine didnt have the same impact. This shows that caffeine isnt automatically a problem with all antibiotics, but it highlights how even common, everyday substances can sometimes tip the balance in bacterias favor.

Such fundamental research into the effect of substances consumed on a daily basis underscores the vital role of science in understanding and resolving real-world problems, President Prof. Dr. Dr. h.c. (Dshisha) Karla Pollmann said in the news release.

Scammers post phony reviews and shake down business owners who want them removed

September 11, 2025

• Scammers demand payments from business owners to remove 1-star reviews

• Victims report losing hundreds of dollars and severe hits to online ratings

• Watchdogs say Google isnt doing enough to protect small businesses

---

Contractors, movers and roofers among targets

Small business owners are being targeted by scam artists who flood Google Maps and other sites with phony false reviews and then extort the business owner, offering to remove the reviews for a price. In a New York Times report, Los Angeles contractor Natalia Piper told of gettinga WhatsApp message from a number in Pakistan this summer. It warned that someone had ordered 20 negative reviews of her business. Soon after, her companys once-perfect 5-star Google rating plunged to 3.6, costing her customers and income.

Piper, like other small business owners, was asked to pay to have the fake reviews removed. She handed over $250 in two separate payments before realizing the cycle would not stop. It took me eight years to get my reputation in the market, and one guy can damage it in one day, she said.

A system ripe for abuse

The scam works by flooding small, review-dependent businesses from moving companies to roofers and appliance repair services with phony one-star Google ratings. The attackers then demand money to delete the posts. Industry watchdog Fake Review Watch has tracked more than 150 businesses worldwide targeted in this way.

Businesses are being extorted and Google isnt doing enough about it, said founder Kay Dean in theTimes report, a former federal criminal investigator. She said scammers use AI tools to churn out convincing reviews at scale, making moderation even harder.

Google under scrutiny

Google, like Amazon and Yelp, removes millions of fake reviews each year but admits many slip through. In a statement, the company said it blocks fraudulent content before it appears in most cases and has suspended more than 900,000 accounts for violations. Officials promised a new tool to help businesses report when they are being targeted, but gave no timeline.

Victims say getting help from the tech giant is nearly impossible. Piper said she tried multiple channels even through Googles advertising department, where she spends thousands with little success.

Real losses for small firms

In Georgia, moving company owner Nick Betourney also saw his hard-won 5-star rating threatened. He received a WhatsApp note from a man using the name Rashid Ghallu, who later admitted to The New York Times that he sells negative Google reviews for $100 per batch of 20.

The scammers reviews werent generic complaints, Betourney said, but crazy elaborate stuff describing boxes smashed in front of customers. Google eventually removed some of the fakes, but new ones quickly appeared.

Limited protections despite new rules

The Federal Trade Commission in 2024 introduced rules targeting businesses that buy fake positive reviews, but they dont apply to platforms like Google or to scammers overseas. Under federal law, platforms enjoy broad protections for third-party content, leaving small businesses vulnerable.

For now, some owners are relying on their own fixes. Piper said removing her cellphone number from her online listings finally stopped the WhatsApp harassment. But she fears countless other small firms may not be as lucky.

Business owners: Tips for spotting and reporting fake reviews

• Watch for sudden rating drops A cluster of 1-star reviews appearing at once is a red flag.

• Look at reviewer profiles Fake reviewers often have no profile photo, few past reviews, or reviews scattered across unrelated industries and locations.

• Check for copy-and-paste language Repeated phrases or nearly identical wording across multiple reviews may indicate fraud.

• Report suspicious reviews to Google Use the Report review option directly in Google Maps; provide details explaining why its fake.

• Keep records Save screenshots of reviews and any related messages (emails, texts, WhatsApp) to document harassment or extortion attempts.

• Avoid paying scammers Payment rarely stops the attacks and can invite more.

Influencers are misleading people who've been scammed on Zelle and CashApp

September 11, 2025

Social media influencers falsely claim CFPB will pay out victims of Zelle and Cash App

Misinformation drives tens of thousands of dubious complaints to federal database

Consumer advocates warn vulnerable communities are being exploited

---

Misusing a federal complaint tool

A new wave of social media influencers is pushing misinformation and dubious financial advice by exploiting the Consumer Financial Protection Bureaus complaint portal.

Two prominent figures, Daraine Delevante and Gilbert Graim Jr., have told followers that filing complaints with the CFPB would result in payments from Zelle and Cash Appclaims that are not true, according to an investigation by ConsumerReports. Both men sell e-books, classes, and complaint templates while promoting this message to audiences numbering in the hundreds of thousands.

The CFPB has accused the payment apps of enabling fraud, but its complaint system is not a path to compensation. At least two of the agencys enforcement actions against the companies have already been dropped.

Dubious claims and false hope

Delevante and Graim have built lucrative businesses selling complaint templates and consumer law advice, much of it misleading. One of Graims TikTok videos urging people to complain against Zelleeven if they had never lost moneywent viral with more than 5 million views.

Delevante, who calls himself The Credit Hero, charges $77 for a downloadable complaint template and has even used AI-generated avatars in videos to make his claims. In July, he told followers they could get medical debt erased by filing a complaint, according to the ConsumerReports article by investigative reporter Derek Kravitz.

Experts at the nonprofit National Consumer Law Center examined their material and called it egregious pseudo-legal advice. They urged consumers misled by the pair to file complaints with the CFPB, the Federal Trade Commission, and state attorneys general.

Complaint surge overwhelms database

The scale of the misinformation campaign is reflected in the CFPBs complaint data. In the first eight months of 2025, more than 61,000 complaints were filed against Zelle and Cash Appnearly 15 times the previous yearly average.

Many of the complaints use nearly identical language lifted from the influencers templates and videos. Yet CFPB data shows that only 15 customers have received refunds from the companies as a result of filing complaints. Nearly all others were denied.

Cash App said fewer than one in 10,000 transactions results in fraud, but acknowledged it has made significant improvements to detecting and acting on complaints. Zelle, meanwhile, says it requires partner banks to reimburse customers in confirmed fraud cases but has not disclosed how much money has actually been returned.

Exploiting the vulnerable

Consumer advocates say the misinformation disproportionately targets financially vulnerable communities, including Black Americans. We need accurate information and financial literacynot social media influencers selling snake oil, said Chicago-based researcher Pepper Miller.

Both Delevante and Graim have faced scrutiny over their businesses, which are now inactive in Wyoming and Texas, respectively, for failing to meet tax requirements. FTC records also show multiple complaints from consumers who said Delevantes products damaged their credit or left them out of pocket.

Weak enforcement fuels confusion

The controversy highlights how the CFPBs weakened enforcement role has created space for misinformation to spread. The agency has been defunded and scaled back much of its oversight of payment apps. A new rule that would have expanded its authority over digital platforms was rolled back by Congress earlier this year.

Advocates warn the vacuum leaves consumers more exposed. It may get worse before it gets better, said Ruth Susswein of the nonprofit Consumer Action. We have to be more skeptical online and push elected officials to deliver genuine protections.

What consumers should do

• Slow down and be cautious. Scammers often create a false sense of urgency to push you into hasty decisions.
• Never share sensitive details. Legitimate bank employees will never ask for your PIN, passwords, or one-time codes.
• Be skeptical of free money claims. If an influencer says you can get a payout without being a fraud victim, its a red flag.
• Report quickly. Contact your bank or payment app immediately. Even if you dont get a refund, your report may help catch criminals and protect others.
• Turn to the right authorities. File complaints with the FTC (reportfraud.ftc.gov), the FBIs Internet Crime Complaint Center (ic3.gov), or your state attorney general.
• Document everything. Keep emails, texts, receipts, and screenshots. Detailed evidence strengthens your case with regulators and law enforcement.
