Yes, in salt water you DO have free sodium and chlorine ions floating around. That's exactly what you have. Sodium (Na+) and Chlorine (Cl-) ions, that is. They are not molecules at this point. Boil off the water and the ionic bonds reform, recreating crystalline salt (NaCl).

Yes, at least one person around here definitely needs to review their chemistry notes. :)

As soon as I see an "ibtimes" domain, I know better than to RTFA. I don't understand why /. ever posts links to their crappy sites unless they're getting kickbacks on click-throughs.

So how about looking for some alternate sources? Googling "Zeleniy Yar mummies" suggests that this isn't some ibtimes hoax after all.

This Siberian Times article seems to have the most information with lots of great pictures, the fewest ads, and other sites credit it as their source:

Corrections & Amplifications

U.S. investigators suspect Malaysia Airlines Flight 370 flew for hours past the time it reached its last confirmed location, based on an analysis of signals sent through the plane's satellite-communication link designed to automatically transmit the status of onboard systems, according to people familiar with the matter. An earlier version of this article and an accompanying graphic incorrectly said investigators based their suspicions on signals from monitoring systems embedded in the plane's Rolls-Royce PLC engines and described that process.

Which, due to Linux's efforts to guard every user account against every other user account, is an absolute nightmare.

With a comment like that, it's quite apparent you don't know much about Linux system administration. You should read up on the appropriate uses of 'sudo' before you go messing things up.

Tesla Model S Has Bizarre 'Vampire-Like' Thirst For Electricity At Night 424

Posted by Unknown Lamer
from the bug-in-acpi-specification dept.
cartechboy writes "The Tesla Model S, for all its technical and design wizardry, has a dirty little secret: Its a vampire. The car has an odd and substantial appetite for kilowatt-hours even when turned off and parked. This phenomenon has been dubbed the 'vampire' draw, and Tesla promised long ago to fix this issue with a software update. Well, a few software updates have come and gone since then, and the Model S is still a vampire sucking down energy when it's shut down. While this is a concern for many Model S owners and would be owners, the larger question becomes: After nine months, and multiple software updates,why can't Tesla fix this known issue? Tesla has recognized the issue and said a fix would come, yet the latest fix is only a tiny improvement — and the problem remains unsolved. Is Tesla stumped? Can the issue be fixed?"

Military Robots Expected To Outnumber Troops By 2023 177

Lucas123 writes "Autonomous robots programmed to scan city streets with thermal imaging and robotic equipment carriers created to aid in transporting ammunition and other supplies will likely outnumber U.S. troops in 10 years, according to robotic researchers and U.S. military officials. 5D Robotics, Northrop Grumman Corp., QinetiQ, HDT Robotics and other companies demonstrated a wide array of autonomous robots during a display at Ft. Benning in Georgia last month. The companies are already gaining traction in the military. For example, British military forces, use QinetiQ's 10-pound Dragon Runner robot, which can be carried in a backpack and then tossed into a building or a cave to capture and relay surveillance video. 'Robots allow [soldiers] to be more lethal and engaged in their surroundings,' said Lt. Col. Willie Smith, chief of Unmanned Ground Vehicles at Fort Benning, Ga. 'I think there's more work to be done but I'm expecting we'll get there.'"

I encourage everyone to ride a mountain bike if you plan on bike on a road with a lot of traffic and potholes!

I read the thread of replies about where you live. Anywhere with that many potholes--and/or if you like to take off-road excursions on a whim--it sounds like a mountain bike is just great for you! On the other hand, for anyone who rides on roads with a lot of traffic (or not) with relatively good road surfaces, I would strongly discourage them from riding a mountain bike. Get a bike that's designed for what you're doing. Mountain bikes are designed for rough- and off-road conditions. They have fat, knobby tires and low gearing, and

  • 1. Fat, low-pressure tires make for a much harder (more difficult) ride--if you're in it purely for the workout, that's great. Otherwise, you're liable to get discouraged and think biking's not for you because it just takes too much effort to get to work and back. (on the other hand, it may result in a more comfortable ride if you don't care about effort).
  • 2. As mentioned elsewhere, knobby tires provide less traction (and probably more rolling friction) on normal road surfaces--more dangerous when you need to brake in a hurry, as you often do in [sub]urban environments.
  • 3. Low gearing means your legs have to spin around a lot faster to go the same speed as a comparable road bike.

I'm not saying the average rider needs a race bike. Au contraire... if you're riding as a commuter or just "around town", getting a (generally expensive) road bike is just as naïve as getting a mountain bike that you'll never take off-road. For the average commuter in relatively flat [sub]urban environment, I recommend a 3- to 8-speed bike (gearing in the rear hub; eliminates all the complication and maintenance of a derailleur setup) with relatively narrow tires... and a comfortable seat. Myself, my normal commuter bike is an old (~1980) Viscount, single-speed (not a fixie, thanks!) with high-gearing (52/16) because I like to go relatively fast. When I'm riding with my family, I ride an old Schwinn 10-speed.

The mini-UAV can be remotely controlled at long standoff distances from ground or an airborne asset. In addition to the programmed, GPS-guided multi-waypoint visits, the integrated video cameras allow for day and night landing and monitoring of a premises under surveillance for enhanced situational awareness."
