Turning off Bluetooth rarely fixes slow Wi-Fi, experts say

Wireless congestion from accumulated smart devices is often blamed on Bluetooth interference with Wi-Fi networks. In reality, most modern routers and devices use frequency management techniques that keep Bluetooth and Wi-Fi signals from significantly interfering with each other, except in specific overlapping scenarios.

Fire Ant hackers convert Cisco IOS XR routers into covert data-collection tools

Incident responders at Sygnia say the China-linked group Fire Ant has expanded from compromising VMware hypervisors to hijacking Cisco routers, TACACS authentication servers, and Linux management hosts. Investigators found a hidden GRE tunnel on a Cisco IOS XR router that didn't match its configuration history, leading to discovery of custom malware that hides its activity from administrators and runs only during set hours. The attackers used their router access to capture network traffic and exfiltrate it to external FTP servers, then pivoted through a hidden tunnel into a Linux server to probe further into connected high-value networks, including ones tied to critical infrastructure.

New study proposes framework for how AI chatbots may reshape human behavior

An international research team published a paper in AI & Society introducing the concept of 'robotoid humanness,' arguing that frequent interaction with AI chatbots in customer service settings could push people toward more machine-like patterns of speech and behavior. The researchers describe this as a two-way process where bots increasingly mimic human traits while humans adapt to communicate in ways that are more legible to machines. The framework outlines three stages of this shift but has not yet been tested empirically.

Microsoft tells users to disregard false Defender Antivirus 'turned off' alerts

Microsoft confirmed a bug causing the Windows Security app to falsely display 'Microsoft Defender Antivirus is turned off' notifications after recent Defender updates, even though protection remains active. The issue, which has quietly affected Windows Insiders since June, now impacts all supported Windows client and server versions, including Windows 11 26H1 and Windows Server 2025. Microsoft says a fix is in development and will roll out in a future Defender update.

SIU Researchers 3D-Print Cookies Using Plastic-Eating Engineered Yeast

Scientists at Southern Illinois University Carbondale used CRISPR-edited yeast strains to break down PET plastic and plant waste into edible proteins, fats, and flavor compounds, which were then 3D printed into small cookie-shaped snacks called 'ÂBites.' The plastic is first broken down using heat, water, and oxygen before the yeast converts it into a food-like slurry, though the team has not yet tasted the cookies pending university approval.

Researcher builds dependency-aware memory system for LLM vulnerability-hunting agents

A security researcher describes building a new memory architecture for LLM agents used in vulnerability research, after noticing that standard retrieval-based memory let models keep reasoning from facts that had since been disproven. Instead of just storing and retrieving past observations, the system tracks logical dependencies between facts, so that when one assumption is invalidated, everything derived from it can be automatically flagged or revised. The approach effectively borrows ideas from program analysis, treating an investigation's knowledge state like a dependency graph rather than a flat log of conversation history.

Investor explains three deal types he rejects despite strong pitches

An early-stage investor and Entrepreneur contributor describes walking away from investments that appear promising on the surface but carry hidden structural risks. He cites examples like a hydration test product with an unworkable cost structure, alongside deals involving founders he can't fully trust or markets dominated by entrenched competitors. The piece frames these quiet rejections as some of his most valuable investment decisions, even though they generate no visible outcomes.

Entrepreneur Guide Details Steps to Convert an E-commerce Niche Into an Actual Business

A new Entrepreneur op-ed argues that identifying a profitable niche is only the first step for e-commerce founders, who often stall by over-researching or polishing websites before validating demand. The author outlines a practical approach: define a single customer and problem, translate that problem into a specific offer, and test it cheaply before scaling.

AI chatbots gain traction as substitutes for human spiritual gurus

After a family in Chennai received what they felt was an insensitive response from a well-known guru following a relative's death, they turned to AI chatbots like ChatGPT for comfort and guidance. Yoga instructor Kripa Vaidyanathan said the AI offered nonjudgmental, round-the-clock support that was easier to access than a human spiritual advisor's limited time.

Google upgrades Flow video tool with Gemini Omni 1.1 Flash model

Google has updated its Flow AI video studio with a new model, Gemini Omni 1.1 Flash, that adds finer editing controls such as first- and last-frame interpolation and longer scene extensions of up to 40 seconds. The update also lets creators produce cheaper, faster 360p drafts before rendering final output in 1080p or 4K, with video references to help keep characters and visuals consistent.
