South Korea's Samsung has hit back at rival LG in a patents row over next-generation display panels, with both firms accusing the other of stealing technology and senior staff to grab a lead in the market.

Samsung Display, an affiliate of Samsung Electronics, asked a Seoul patents court last week to annul seven patents related to organic light-emitting diode (OLED) panel technologies held by LG, a company spokesman said Monday.

The Israeli government on Sunday admitted it had become the victim of a mass cyber-warfare campaign with millions of attempts to hack state websites since the start of its Gaza offensive four days ago.

Speaking ahead of the weekly cabinet meeting, Israeli Finance Minister Yuval Steinitz said the government was now waging war on "a second front -- of cyberattacks against Israel."

Online activist group Anonymous said on Saturday it had downed the websites of dozens of Israeli state agencies and a top bank in protest over the Jewish state's deadly air assault on Gaza.

The hackers said their operation "OpIsrael" had either damaged or completely erased the sites of more than 650 private and public institutions that included the Bank of Jerusalem -- one of the country's main finance houses.

Fifteen solar panel vehicles, some that look like small space ships, raced across Chile's Atacama desert Friday as part of a contest to build low-cost environmentally-friendly cars.

A movement by privacy activists to curb tracking of Internet users' browsing habits scored a major victory last month when Microsoft launched its new browser with "do not track" as the default, or automatic setting.

Afghanistan has launched a new literacy program that enables Afghan women deprived of a basic education during decades of war to learn to read and write using a mobile phone.

The phone is called Ustad Mobile (Mobile Teacher) and provides national curriculum courses in both national languages, Dari and Pashto, as well as mathematics.

It can scan zombies, replace a TV remote, open a window into virtual worlds and shoot ninja stars across a living room. It's the Wii U GamePad, the 10-by-5-inch touchscreen controller for the successor to the Wii out Sunday, and if you ask the brains behind the "Super Mario Bros." about it, they say it's going to change the way video games are made and played.

"You can't manufacture buzz," said Nintendo of America president Reggie Fils-Aime. "You can't manufacture word of mouth. All we can do is to provide the product and the games to foster some sparks that hopefully enable that to happen. We think we have that with Wii U."

The artsy downloadable game "Journey" leads the pack of nominees for this year's Spike Video Game Awards.

Twitter on Thursday introduced a new feature to the globally popular one-to-many text messaging service -- the ability to email "Tweets" directly from the message stream.

Katey Klippel makes a point of keeping her smartphone in her bag when she returns home from a hard day at the management consulting firm where she works in Washington.

That way, she can better practice what her employer preaches and stop checking her emails after hours.
