When massive, open-pit mines like the Minera Escondida —in Chile’s Atacama Desert—need to pull millions of tons of minerals out of the ground each year, they rely on fleets of huge, “Ultra-Class” haul trucks. The ETF Haul Train, however, pulls four times the minerals of these stone-toting behemoths with just one driver. More »

Every one of the modern US Navy’s 129 ships, and its entire fleet of aircraft, relies on gas turbines for either basic propulsion or to generate electricity for their critical systems—typically both. But as fuel costs continue to rise, these turbines now burn through nearly $2 billion of fuel annually. That’s why the Naval Research Lab is developing a revolutionary new type of engine that could reduce our armada’s energy consumption by as much as 25 percent (and save $400 million a year) even as the Navy transitions to “all electric” propulsion systems.

Romans may have used 20-Sided die almost two millennia before D&D , but people in ancient Egypt were casting icosahedra even earlier. Pictured above is a twenty-faced die dating from somewhere between 304 and 30 B.C., a timespan also known as Egypt’s Ptolemaic Period . More »
Technology moves fast. So fast, in fact, that great apps often get left in the dust if they don’t come out of the gates full-featured and ready for primetime. With that in mind, here are a few apps that all but disappeared from our radar, but still offer a great feature-set. More »

Three years ago, scientists discovered electric currents running through the seabed — but they had no idea what was causing it. But now, researchers from Denmark and the United States believe they have the answer: bacteria that function as living electric cables. In a remarkable case of biological engineering, scientists have confirmed that each tiny section of the bacteria contains a bundle of insulated wires that leads an electric current from one end to the other.

A few months back at the Black Hat Security conference Cody Brocious demonstrated how you can easiy open an Onity hotel room lock, the standard system used in many hotel chains, with an Arduino but it was bulky setup and comletely obvious if anyone saw him pull out a lot of electronics. Here’s how you can fit that system in a dry erase marker. More »
