Fighting fire with an electric-field generating "magic wand":
Researchers say they've found a new way to snuff out flames using an electric field-generating wand -- and the seemingly magical technique just might be put to use in future fire rescues...
The technology sounds a bit like the fictional flame-freezing charm or the Aguamenti spell mentioned in J.K. Rowling's series of Harry Potter books, and the fact that it's done with a wand-like electrode makes the story even better. "The best geometry of the electrode is in the form of a thin wire, which journalists creatively labeled a wand," [Harvard researcher] Cademartiri said.

Clever Bat-themed mirror:
"As far as Batman-themed mirrors go, you probably won't find one more suitable for you neo-rococo style mansion than this one. In fact, your snobbish guests might not even notice when they gaze into it to check and see if their gigantic hats are in order."

Thieves hacking ATM users by glueing down the "Enter", "Clear", and "Cancel" keys:
The thieves glue down the "enter," "cancel" and "clear" buttons on the keypad and wait until the customer goes into the bank for help before withdrawing money from their account.(Via Bruce Schneier.)
The robbed customers have already punched in their PINs when they realize the keypad buttons are stuck. The unwitting customers either do not know that they can use the ATM touchscreen to finish their transaction, or become nervous when the keypad isn't working and react by leaving the ATM unattended...

"Can You Judge a Person by His E-Mail Address?"
[Gmail users are] well-traveled, career-focused, tech-savvy agnostics. The site also found that they're partial to "salty snacks" and lounge around their apartments in T-shirts and jeans.
Yahoo users, on the other hand, tend to be overweight women ages 18 to 49, with high-school diplomas, children and a sweet tooth.
Hotmailers are more likely to be suburban women of average build, aged 18 to 34, according to Hunch. They're more likely childless, not religious and pessimistic.
The @AOL crew -- the oldest of the bunch -- tend to put family first, read magazines and live in the suburbs. They likely haven't traveled internationally, but are considered "optimistic extroverts."

"Scientists reverse Doppler Effect":
Being able to reverse the Doppler Effect is a promising sign for the future development of science-fiction inspired technology such as invisibility cloaks. According to Professor Gu this technology, which has already been demonstrated on a micro-scale by US researchers, may be closer to becoming a reality than most people think.

"DroidDream Autopsy: Anatomy of an Android Malware Attack":
DroidDream is a powerful zombie agent that can silently install any applications and execute code with root privileges at will. According to Lookout, DroidDream is also the first piece of Android malware that uses an exploit to gain root permissions and assume virtually limitless control of the infected smartphone.
The elephant in the room, though, is the fact that DroidDream exploits vulnerabilities that have already been identified and patched, but that 99 percent of Android users are still exposed because their smartphone has not yet been graced with the update to Gingerbread.

"Five things you never knew about Pac-Man". Among the tidbits:
...[O]nly Blinky, the red ghost... doggedly pursues you throughout the game. Pinky, the pink ghost (naturally), simply wants to position itself at a point that's 32 pixels in front of Pac-Man's mouth. The blue ghost, Inky, is seeking to position itself at a similar fixed spot. And Clyde, the orange ghost, moves completely at random.(Via GMSV.)
