Sharper than Sharp

A phrase I'd heard and had found myself repeating uncritically was that regarding high-megapixel camera sensors "out-resolving" the lenses that were on them. It came to mind again recently when I saw stuff like this. That Six-Four Impala was shot with a 36MP Nikon D800 using a mid-'90s vintage Nikon 35-105mm f/3.5-4.5 AF-D lens. At first glance, it looks okay, but blow up to full screen or (worse) start pixel peeping at 100% magnification and something's...off. The lines of the car have a bi...

How atomic time-travel could reveal the mysteries of dark matter and more

Physicists from the University of Colorado have created an atomic clock so precise it can measure gravitational time dilation over distances as small as one millimeter. This record-breaking measurement could have implications reaching as far as redefining exactly how long a second is or discovering where all the dark matter in our universe is hiding. Up front: Einstein figured out that time functions differently depending on how close to a “gravity well” the observer is. So, for instance, if you...

Tests by the state research centre showed that a relatively new strain of lethal avian flu known as H5N8 was circulating, and within days 900,000 birds at the Vladimirskaya plant were hurriedly slaughtered to prev...
