With quercetin as a natural reducer and stabilizer, ZnS quantum dots break down stubborn dyes and disrupt bacterial biofilms, all while remaining safe for healthy cells. Study: Green synthesis of quercetin-mediated ZnS quantum dots and their photocatalytic, antimicrobial, and cytotoxic performances. Image Credit: Sinhyu Photographer/Shutterstock.com In a new Scientific Reports study, researchers demonstrate an environmentally friendly method for producing zinc sulfide (ZnS) quantum dots using quercetin, a plant-derived flavonoid that doubles as a reducing and stabilizing agent. Quantum dots (QDs) exhibit unique optical and electronic behaviors when their dimensions fall below the exciton Bohr radius, approximately 10 nm for ZnS. These nanoscale…

Picture this. You’ve joined a squad at your company that’s designing new product features with an emphasis on automation or AI. Or your company has just implemented a personalization engine. Either way, you’re designing with data. Now what? When it comes to designing for personalization, there are many cautionary tales, no overnight successes, and few guides for the perplexed.  Article Continues Below Between the fantasy of getting it right and the fear of it going wrong—like when we encounter “persofails” in the vein of a company repeatedly imploring everyday consumers to buy additional toilet seats—the personalization gap is real. It’s…

When the head of Nokia Bell Labs core research talks about “lessons learned” from 5G, he’s doing something rare in telecom: admitting a flagship technology didn’t quite work out as planned.That candor matters now, too, because Bell Labs core research president Peter Vetter says 6G’s success depends on getting infrastructure right the first time—something 5G didn’t fully do.By 2030, he says, 5G will have exhausted its capacity. Not because some 5G killer app will appear tomorrow, suddenly making everyone’s phones demand 10 or 100 times as much data capacity as they require today. Rather, by the turn of the decade,…

In a departure that took almost as long as Siri needs to find some obscure music requests, Apple has announced a new vice president of AI: Amar Subramanya, who will replace former AI chief John Giannandrea. Subramanya will report directly to Craig Federighi, Apple’s senior vice president for software engineering. Giannandrea will “transition to an advisory role” pending planned retirement next year. Certain roles previously occupied by Giannandrea will be shifted to Apple COO Sabih Khan and Senior Vice President for Services Eddy Cue. Subramanya will lead Apple Intelligence and Siri’s next chapters. “We are thankful for the role John played in…

Podcasts Trent Edwards used to climb telephone poles. Now he’s the CEO of TAK Broadband, bringing with him an appreciation for network builders and the often-dangerous work they perform. By Brad Randall, Broadband Communities Trent Edwards, the CEO of an end-to-end fiber network construction firm called TAK Broadband, is worried about the future of industry’s workforce. “We don’t do a good job of making sure that the younger generation understands the opportunity within construction,” he said. According to Edwards, many hold assumptions that construction work is unpleasant because it requires working outside in many different conditions. “And the people that do…

The following article originally appeared on Medium and is being republished here with the author’s permission.Don’t get me wrong, I’m up all night using these tools.But I also sense we’re heading for an expensive hangover. The other day, a colleague told me about a new proposal to route a million documents a day through a system that identifies and removes Social Security numbers.I joked that this was going to be a “million-dollar regular expression.”Run the math on the “naïve” implementation with full GPT-5 and it’s eye-watering: A million messages a day at ~50K characters each works out to around 12.5…

This post shows how Amazon EMR 7.12 can make your Apache Spark and Iceberg workloads up to 4.5x faster performance. The Amazon EMR runtime for Apache Spark provides a high-performance runtime environment with full API compatibility with open source Apache Spark and Apache Iceberg. Amazon EMR on EC2, Amazon EMR Serverless, Amazon EMR on Amazon EKS, Amazon EMR on AWS Outposts and AWS Glue use the optimized runtimes. Our benchmarks show Amazon EMR 7.12 runs TPC-DS 3 TB workloads 4.5x faster than open source Spark 3.5.6 with Iceberg 1.10.0. Performance improvements include optimizations for metadata caching, parallel I/O, adaptive query…

At re:Invent we announced Aurora DSQL, and since then I’ve had many conversations with builders about what this means for database engineering. What’s particularly interesting isn’t just the technology itself, but the journey that got us here. I’ve been wanting to dive deeper into this story, to share not just the what, but the how and why behind DSQL’s development. Then, a few weeks ago, at our internal developer conference — DevCon — I watched a talk from two of our senior principal engineers (PEs) on building DSQL (a project that started 100% in JVM and finished 100% Rust). After…

The holiday season brings great deals, busy schedules, and… a spike in online scams. Cybercriminals know shoppers are rushing, distracted, and eager to grab limited-time offers. That makes November and December the perfect time for them to launch phishing campaigns, set up fake websites, and impersonate delivery companies. The good news? With a few simple habits, you can dramatically reduce your risk of playing victim this holiday season. Below are five practical, easy-to-follow ways to protect yourself, including expert tips from Matt Chmel, head of Cyber, North America at Aon. 1. Pause before you buy Scammers count on consumers making…

This year was a busy one for updates to four widely used corporate climate target-setting and carbon-accounting frameworks.  Next year will be even busier, as companies grapple with shifting geopolitics, review progress against their existing near-term emissions reduction commitments and look beyond 2030 to set new ones. Here’s a cheat sheet for what to expect next from B Lab Global, the Greenhouse Gas (GHG) Protocol, the International Organization for Standardization (ISO) and the Science Based Targets initiative (SBTi).  Certified B Corporation Governing organization: B Lab Global What’s new: The seventh edition of the standard used by roughly 9,500 companies carrying…
