Coffee at Night? Bad Idea for Your Brain☕🧠

Happy Monday 👋 , We might have to think twice before that late-night coffee. Well, that’s what they said! A new study from the University of Montreal reveals caffeine doesn't just keep you awake, it actively alters your brain’s inner workings during sleep. Researchers have found that caffeine prompts the brain to enter a state called "criticality," where it becomes hyper-efficient at processing information, but less capable of powering down for true rest. This means even if you do fall asleep after a late cup, your brain may be too stimulated to truly recharge.
EEG scans of participants revealed a significant decrease in deep, slow brain waves associated with memory consolidation and recovery, particularly in younger adults aged 20 to 27. With more active adenosine receptors, younger brains are particularly vulnerable to caffeine’s after-hours effects. The next time you're tempted by a nighttime latte, consider this: your brain might stay wired even while you sleep. Curious how this impacts learning, decision-making, or long-term cognitive health? The research is only beginning to uncover the ripple effects. Read More

FAA is finally replacing floppy disks and Windows 95 in air traffic control systems
🛫💾 It's 2025, and the FAA is finally grounding its use of floppy disks and Windows 95 in air traffic control systems. After decades of relying on paper strips and legacy software from the '90s, the agency is moving toward a digital overhaul. FAA chief Chris Rocheleau confirmed the agency's intent to leave behind outdated tech that’s become not just obsolete but unsustainable. With over a third of systems at risk of failure, the urgency is no longer optional; it's critical.
The scope is massive. Transportation Secretary Sean Duffy calls it the most important infrastructure project in decades, with a cost running into the tens of billions. Yet questions loom: Can this be done in four years? Will new systems meet the sky-high safety standards required? A coalition called Modern Skies is pushing hard, and with an open call for tech proposals already underway, this could be the most high-stakes tech upgrade of our time. Curious who's going to rewrite the digital backbone of American aviation? So is the rest of the world. Read More
AI Cheating Is So Out of Hand In America’s Schools That the Blue Books Are Coming Back
📝🤖 AI’s takeover of America’s classrooms has reached a tipping point, forcing educators to dust off the humble blue book. As apps like ChatGPT make cheating easier than ever, universities are seeing a surge in demand for these traditional pen-and-paper exam booklets. Schools from Texas A&M to UC Berkeley report blue book sales soaring by up to 80%, signaling a pushback against the AI-driven shortcuts that threaten academic integrity.
But while the blue book’s comeback is a bold stand against digital deceit, experts warn it’s not a silver bullet. The in-class essay format can’t fully replace the depth and rigor of traditional take-home papers, leaving educators scrambling for solutions in an evolving landscape. With nearly 90% of students admitting to AI use on assignments and detection tools falling short, the education system may soon face new rules and regulations to combat this modern challenge.

The winners and losers of Google’s AI Mode
🤖🔍 Google’s AI Mode is shaking up the search landscape, creating clear winners and losers in the process. On the plus side, Google itself gains a huge edge by embedding AI directly into its massive search platform, allowing longer, more complex queries and serving context-rich ads that could boost revenue significantly. Advertisers and retail media networks are also poised to benefit, especially those who can adapt to hyper-personalized, conversational ad experiences tailored to niche searches and buying intent.
Publishers, however, face tough challenges as AI-generated summaries reduce click-throughs to their sites, threatening their traditional ad revenue streams. News, product review, and recipe sites are among the hardest hit, as AI Mode pulls content without always driving traffic back. SEO consultancies are also scrambling to pivot amid Google's shift to AI-driven contextual relevance over traditional keyword tactics. The changing metrics and opaque reporting mean publishers and marketers alike must rethink strategies to thrive in this new era of AI-powered search. Read More

The world's largest deposit holds 99.999% of all gold on Earth
💰🌍 Gold has long fascinated humanity not just for its gleaming beauty but for its unique properties; it’s chemically inert, malleable, and an excellent conductor, making it indispensable across industries. Yet, the gold we see and trade is just a fraction of what Earth holds. Recent research from the University of Göttingen reveals that the majority of gold lies deep in our planet’s molten core, locked away since Earth’s formation 4.5 billion years ago. While this treasure trove remains unreachable, tiny traces of precious metals like ruthenium detected in volcanic rocks suggest that elements from the core are slowly migrating upward through volcanic plumes, offering a tantalizing glimpse of this hidden wealth.
But here’s the twist for entrepreneurs and investors: Patience is key. The gold from Earth’s core surfaces at a geological pace, meaning tapping into these resources directly is currently out of reach. However, the study opens doors to exciting possibilities beyond our planet, such as asteroid mining. Celestial bodies like Psyche could hold mineral riches worth quadrillions, redefining how we think about resource acquisition in the future. Read More
