It's been more than a year since the Coolpix P100 hit the review panels, and now it's time for the new kid on the block to step up. The fine folks over at Photography Blog seem to find that the P500 performs similarly to the P100 -- the Achilles heel still being image quality, suffering from the same washy retention of detail. The overall handling and controls haven't changed much either -- a second control wheel, the ability to mount an external flash, as well as dedicated ISO and white balance buttons are all still missing. With rather modest changes, the P500 gives you another dose of what the P100 served up -- convenience in a compact package. Besides being able to zoom 10x more with that 22.5-810mm monstrous lens, and take larger pictures due to a 2 megapixel increase, the P100 is still faster (with a f/2.8 lens) and smaller, not to mention $100 cheaper. It's difficult to say that the P500 is ready to grab the reins from the P100 entirely, but that miniature telescope of a lens sure makes it a contender. Hit up the source for the full analysis.
As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg
