The rise of AI has created an almost insatiable appetite for computing power. Training and running AI systems requires vast numbers of transistors, and engineers are now racing to pack more of them onto every chip. With their existing designs, however, silicon transistors are rapidly running up against physical limits on how small they can…

New evidence shows that an asteroid about 160 meters wide struck the seabed roughly 43 to 46 million years ago. The impact triggered a tsunami more than 100 meters high and left behind a crater that geologists debated for years.
