For nearly a decade, NVIDIA has been the unchallenged emperor of AI silicon. Its CUDA ecosystem was the moat, its GPUs the castle walls, and its profits, 75% margins to be exact, were the gold piled inside. Then OpenAI went and pulled a Julius Caesar. In October 2025, it forged a 6-gigawatt alliance with AMD, splitting its AI infrastructure between NVIDIA’s familiar green glow and AMD’s upstart Instinct hardware. On paper it’s diversification; in reality it’s an act of rebellion. NVIDIA once powered OpenAI’s entire 10-gigawatt AGI factory. But the empire got greedy. The so-called “NVIDIA tax” made every new

War has gone quiet. The weapons don’t explode anymore; they hum. Somewhere, a machine scans the sky for drones and fires an invisible pulse that fries them mid-flight. No smoke, no shrapnel, just silence, the kind that feels like the world holding its breath. This is the age of directed energy weapons, tools that replace bullets with beams. High-Power Microwaves are at the front of this revolution, turning electrical energy into focused radio waves powerful enough to melt circuitry and erase guidance systems. They travel at the speed of light, have no ammunition limits, and cost almost nothing per shot.

There’s a certain poetry in the idea of warships turning the sea beneath them into the fuel that powers their planes above. It’s the kind of concept that sounds like either science fiction or military PowerPoint optimism, but this one called Project GENESIS or the more cinematic Sea Dragon is very real. And it might just change global energy logistics forever. The US Navy’s Seawater-to-Jet-Fuel (S2J) programme aims to do something that borders on alchemy: pull carbon and hydrogen out of seawater and turn it into jet fuel. The trick lies in using the ocean’s abundance seawater contains roughly 140

For decades, Alzheimer’s research has been like shouting at a locked door. Billions spent, countless theories tested, and all we’ve learned is that the door’s still locked and we’re hoarse. Now, for the first time, someone may have found the key, and it’s not what anyone expected. Instead of targeting the neurons, the plaques, or any of the usual suspects, researchers went for the brain’s bouncer: the blood brain barrier. It’s the structure that keeps the brain safe from the chaos of the bloodstream. In Alzheimer’s, that barrier starts to fail. It lets toxins creep in and stops clearing out

Psychiatry is a field where progress is often measured in slow, uncertain steps. Treatments take years to develop, and many bring as many problems as they solve. Every so often, however, something appears that could mark a real shift. One of the latest is PA915, a molecule that may reshape how stress and mood disorders are treated. PA915 works by blocking the PAC1 receptor, a key part of the body’s stress response system. The receptor ensures the body reacts when challenges arise, but when it becomes overactive it traps people in a cycle of chronic stress, anxiety, and depression. By
