A Navy laser set fire to a small ship bobbing in unruly seas this week, the first at-sea demonstration of one of the Navy’s ray guns. Check out the Navy’s video of a fire slowly consuming the inflatable boat’s outboard motors. More
We can’t say we’re pleased that camera makers still haven’t called an armistice in their megapixel war, but a race for the speediest memory card is one battle we can get behind. Delkin says its 32GB Elite 633 SDHC is the fastest in the world, with 80MBps and 95MBps write and read speeds, respectively, handily trumping Sony’s new Memory Sticks that so recently impressed us. This card’s ideal for people who shoot gobs of 1080p video, 3D movies, and high-resolution shots coupled with RAW files, but with a price of $440, it’s only worth it for pros. And debutants.

IBM might be cautious about touting graphene as a a silicon killer, but that hasn’t stopped it from pushing the production of ever faster graphene transistors. With the recent demonstration of a 155GHz graphene transistor, the firm successfully outdid its previous record-setting efforts, which produced a cut-off frequency of 100GHz. What’s more, the thing is also IBM’s smallest to date, with a gate length of 40 nanometers; that’s 200 nanometers less than the 100GHz iteration. This smaller, faster transistor was produced as part of a DARPA research project that aims to develop high-performance RF (radio frequency) transistors. So, no, we probably won’t be seeing the things in our PCs anytime soon, but it looks like they could be right at home in war machines of the future.
