**OpenAI Brings Health Intelligence to ChatGPT, Blending Personal Data into Everyday Conversations** OpenAI has rolled out a major update to ChatGPT, introducing a built-in Health feature designed to make medical information more accessible and actionable within everyday conversations. Rather than relegating health data to a separate compartment, the new functionality allows ChatGPT to draw on users’ personal health records and Apple Health data directly in the chat interface—provided users grant explicit permission. ### What the New Health Feature Does The feature allows logged-in users aged 18 and older to connect Apple Health data as well as medical records from select…

## Demystifying Fluid Flow: Simulating Kármán Vortices with the Lattice Boltzmann Method The sight of alternating, swirling vortices trailing behind a blunt object in a flowing stream is one of the most iconic and recognizable patterns in all of physics. This intricate dance, known as a Kármán vortex street, is a staple of fluid dynamics, famously visible behind everything from bridge pillars and airplane wings to towering chimney stacks. For centuries, our understanding of such phenomena has been rooted in the Navier-Stokes equations—the fundamental laws governing fluid motion. However, what if I told you that you could generate this complex,…

**Understanding Modern Phishing Attacks: The Shift to Real-Time Account Hijacking** In recent years, phishing campaigns have evolved significantly, moving from simple credential harvesting to more sophisticated, real-time account takeover methods. A recent investigation into insurance-focused phishing operations reveals an alarming trend: attackers are now synchronizing their actions with victims in real time, compromising accounts during the login process itself. This shift marks a new era in phishing threats, where the goal is no longer just data theft, but immediate and active exploitation of credentials. — ### **Insurance: A Prime Target for Phishing** Insurance providers have increasingly digitized their services, offering…

**Big Tech Earnings Week: The Real Winners and Losers** Big tech earnings week closed with a strange scoreboard. Most companies beat Wall Street’s estimates, yet almost every stock fell, and hundreds of billions of dollars in market value vanished in two sessions. This divergence highlights that price reaction, money flow, options positioning, and analyst revisions tell the true story of who won the week. ### Why This Big Tech Earnings Week Mattered Seven tech giants reported earnings over four days, serving as the first major test of whether massive AI capital expenditures are translating into profit. Collectively, these companies shed…

**AT&T and Microsoft Foundry: Powering Next-Generation AI for Telecom** AT&T, one of the world’s largest telecommunications providers, is actively pursuing artificial intelligence to enhance its operations, from customer service to network optimization. However, the unique complexities of telecom demand more than off-the-shelf AI. Unlike other industries, telecommunications involves highly specialized networks, strict standards, and intricate operational workflows. Generic models, trained on broad internet data, often miss the mark—struggling to understand network topology, signal protocols, or billing systems. To solve this challenge, AT&T created **Open Telco (OTel)**—a family of AI models purpose-built for telecom. OTel represents a shift from general-purpose AI…

**Light Flip: The Minimalist Flip Phone for the Digital Detox Era** Follow ZDNET: **Add us as a preferred source** on Google.

Enter Light, the company that successfully pioneered the “premium dumbphone” with its original Light Phone. Challenging the status quo of tech conglomerates, Light has always championed a return to simplicity. Now, with the announcement of the **Light Flip**, the company doubles down on its mission, offering a $299 minimalist flip phone…

## Building Scalable Vector Search: ANN Algorithms and Cost Trade-offs Vector search has become a critical piece of AI infrastructure, powering use cases from RAG and semantic search to agentic memory and context layers. With the rise of agentic systems, companies are trying to provide as much context to the agents as possible, which requires vector DB indexes to grow from an initial million or dozens of millions scale to the hundreds of millions or even billions. At this scale, storing indexes and associated data in RAM will cost thousands of dollars per month, and HNSW can become a scalability…

**Trading Cards and Bitcoin: A New Era of Collectibles** The world of trading cards has undergone a dramatic transformation. What was once a simple hobby has evolved into a full-fledged spectator sport. Today, millions watch live streams as individuals tear open foil packages, and the card market has reached unprecedented highs, with rare cards fetching eight-figure sums. However, this frenzy has revealed a deeper issue: the obsession with anticipation over the actual cards themselves. At the heart of this boom are difficult questions surrounding grading. The past year saw the dominant grading house face criticism after grades shifted post-buyback, raising…
