Brain aging shows nonlinear transitions, suggesting a midlife "critical window"

Walmart is stepping up its drone delivery game by adding five more cities to its service, with Atlanta now on the list. This expansion means more customers can get everything from groceries to last-minute essentials dropped at their doorstep in minutes—no traffic, no lines, just quick and convenient shopping from the sky.

Editor’s Note: Drone delivery isn't just a futuristic gimmick anymore—it's becoming a real part of how we shop. Walmart's move signals a bigger shift in retail: companies are betting on speed and convenience to keep customers hooked. For folks in these cities, it’s a win; for everyone else, it’s a peek at where shopping is headed.

Jackery just dropped an upgraded version of its Explorer 2000 portable power station, and it’s a double win: better battery tech (thanks to LiFePO4) and a hefty price cut—nearly $500 off. Whether you’re prepping for blackouts, camping off-grid, or powering tools on a job site, this thing’s got you covered.

Editor’s Note: Portable power stations are having a moment as more people look for reliable backup energy—whether for emergencies or adventures. Jackery’s move makes a premium product way more accessible, which could shake up the market and push competitors to follow suit. If you’ve been eyeing one of these, now’s the time.

Samsung's running a sweet deal where if you buy their massive 49-inch Odyssey QD-OLED G9 gaming monitor (which is already on sale), they'll throw in a free 32-inch M70D smart monitor. Basically, it's a two-for-one for gamers and multitaskers who want a premium setup without paying full price for both screens.

Editor’s Note: For anyone building a high-end PC setup—especially gamers or hybrid work-from-home folks—this is a rare chance to snag a bonus display. Samsung’s Odyssey monitors are top-tier, so getting a free secondary smart monitor (which normally costs a few hundred bucks) makes the deal even juicier. If you were already eyeing an upgrade, now’s the time.

Meta’s Oversight Board is calling out the company for not taking strong enough action against deepfake scams featuring celebrities. These scams often use AI-generated videos or images of famous people to trick users into handing over money or personal info. The board says Meta’s current policies are too narrow, leaving gaps that scammers exploit.

Editor’s Note: Deepfake scams are getting sneakier, and if big platforms like Facebook and Instagram don’t step up, more people could fall for them. This isn’t just about fake endorsements—it’s about real financial harm and eroded trust online. When even Meta’s own oversight group says the company’s efforts are falling short, it’s a sign the problem’s worse than it seems.

The CEO of drone-maker Quantum Systems, Florian Seibel, explains how drones have become a game-changer in modern warfare, particularly in Ukraine's fight against Russia. He argues that these unmanned systems have helped balance the odds despite Russia's military superiority. Seibel also stresses the urgent need for the US and Europe to ramp up drone production—thousands of them—to stay competitive in this new era of conflict.

Editor’s Note: Drones aren't just gadgets anymore—they're reshaping how wars are fought. Ukraine's effective use of them against a much larger force shows how smaller nations can leverage tech to defend themselves. But Seibel's warning about scaling production hints at a bigger arms race brewing, where drone capabilities could decide future conflicts. If the West doesn't keep up, it risks falling behind in a critical defense sector.
