In an Army Corps of Engineers press release, details on the astounding rate at which workers are draining water from New York's subway and transit tunnels: "To date, the USACE has used about 50 pumps of various sizes to remove 64 million gallons of water from the New York City mass transit system. Operations are ongoing at six sites, with pumps removing about 116,000 gallons per minute. The 696,000 gallons the pumps are draining each minute exceeds the amount of water in one Olympic-size swimming pool (660,000 gallons). There were roughly 600 million gallons in the tunnels when pumping operations began on Thursday, Nov. 1." (via Noah Shachtman).
Smarter Every Day announced a series on going to the moon, and the first intallment looks at the logistics and engineering problems that had to be solved to make it work: We're going back to the moon, and we're going to need to train Astronauts how to land.

Watch as a tour guide pulls space shuttle tile material out of a 2200-degree furnace and picks it up immediately. Note that for best results, pick it up by the cool corner or edge rather than the white-hot center. If you're interested in the material and engineering, here is a great PDF on their thermal… READ THE REST
Ice is an abundant material in the solar system and researchers are exploring whether it can be used to build and repair robots. University of Pennsylvanian engineers presented their early work on ice as a structural material for robots in a paper at the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS). The idea… READ THE REST
Valentine's Day is no holiday to sleep on. And, unlike Christmas, you don't really have to get super creative about just the right Valentine's Day gift for your sweetheart, either. The reality is, the recognition and attention coming on the day designated for love is usually enough acknowledgment to satisfy most partners. The simple, traditional… READ THE REST
Every tool on your tool belt strives to be the…(pause for dramatic effect)…LAST TOOL YOU'LL EVER NEED! In reality, that's a mighty tough bar to clear. In most cases, a tool should probably settle for getting a primary job done while handling a few other odds and ends quickly and effectively. But, with 26 features… READ THE REST
If you're a fan of games based around techno-hackers running amok like Cyberpunk 2077 or Watch Dogs: Legion, you might think you're already halfway to being a professional hacker yourself. Unfortunately, a professional ethical hacker can tell you that learning to hack from playing these games is about as likely as learning to fly by… READ THE REST
