Sharp rolls out high-res IGZO LCDs destined for tablets, laptops and monitors

Sharp rolls out high-res IGZO LCDs destined for tablets, laptops and monitors
Well, a week (or two) is a long time in the technology industry, and despite that joint venture with Sony heading south, it's not all bad news for Sharp. According to a press release from the panel maker, it has begun production of the world's first screens based on IGZO (indium gallium zinc oxide) technology. These screens are said to promise twice the detail as existing panels of similar transparency, which also translates into a hefty 90 percent reduction in power consumption, reports PC World. Sharp did kindly share some sample specifications, such as a 7-inch tablet display touting a 1280 x 800 resolution equaling 217 ppi, and a 32-inch 3840 x 2160 screen at 140 ppi, to give you an idea of what we can expect. There's no indication yet as to any devices where we might see them showing up, but as the firm claims it's ramping up production "to meet market demand" we guess we'll find out soon enough...

Jada Pinkett Smith on Divorce Rumors: Untrue!


She has already addressed the infidelity rumors via song, but now Jada Pinkett Smith is doing it via statement.

With tabloid chatter continuing to claim that she and husband Will Smith are headed for a divorce, the actress told French magazine Gala this week: "Every year, one celebrity couple is under the microscope. This year, unluckily, it's us! I almost want to say that we should have been expecting it."

So Jada did not sleep with Marc Anthony? And Will, as rumored in the cover story below, is not having an affair with pal Duane Martin?

"Will and I know the truth. We're waiting peacefully for the storm to blow over," Jada said, adding more forcefully: "These rumors are completely untrue. I travel a lot because of my work, just like Will does.... But our lifestyle hasn't changed."

Okay. Glad that's settled. Now, about your daughter's hair...

Walkie Talkie App Voxer Goes Big, IVP And Intel Lead $30 Million Round

1_PTT_webVoxer, a walkie talkie mobile app that lets you talk to friends across iPhones and Androids, looked like an overnight success last November when it soared to its current place as a top social networking app in the app stores. But the company is five years old and has been working hard to figure out the software and design it needed to win big. It's ready to go all the way, having just closed a funding round of more than $30 million led by Institutional Venture Partners, Intel Capital and numerous angels, I've heard from multiple source. The company has confirmed the amount and agreed to share more -- but it didn't confirm the valuation, which I hear ended up at $180 million pre-money after a couple months of discussions with many interested investors.

Card spending up in retail, hospitality | Stuff.co.nz

Shoppers spent more on their eftpos and credit cards in core retail sectors last month, but a drop in spending on fuel and non-retail items dragged overall card spending down.

Total card spending slipped 0.2 per cent on February, according to seasonally adjusted Statistics New Zealand figures.

Core retail card spending lifted 0.5 per cent, thanks in part to a $12 million (2.1 per cent) boost in hospitality.

That lift was offset by falls in fuel spending, down 2.5 per cent or $16m, and non-retail (excluding services spending), down 1.8 per cent or $21m.

Spending across all retail industries, including fuel and vehicle-related sales, was up 0.3 per cent.

The increase in hospitality spending is a recovery from February, when it fell 2.5 per cent or $15m on January.?

Card spending slipped in February, suggesting a lingering Rugby World Cup hangover.

Cooperative Neural Networks Suggest How Intelligence Evolved

Working together can hasten brain evolution, according to a new computer simulation.

When programmed to navigate challenging cooperative tasks, the artificial neural networks set up by scientists to serve as mini-brains "learned" to work together, evolving the virtual equivalent of boosted brainpower over generations. The findings support a long-held theory that social interactions may have triggered brain evolution in human ancestors.

"It is the transition to a cooperative group that can lead to maximum selection for intelligence," said study researcher Luke McNally, a doctoral candidate at Trinity College Dublin. Greater intelligence, in turn, leads to more sophisticated cooperation, McNally told LiveScience. [10 Fun Brain Facts]

It also leads to more sophisticated means of cheating, he added.

Virtual neurons
McNally and his colleagues used artificial neural networks as virtual guinea pigs to test the social theory of brain evolution. These networks are the numerical equivalent of very simple brains. They're arranged in nodes, with each node representing a neuron.

"In the same way that neurons excite each other via signals [in the brain], these nodes pass numbers to each other, which then decides the activity of the next node," McNally said.

The neural networks are programmed to evolve, as well. They reproduce, and random mutations can introduce extra nodes into their networks. Just as in real-world evolution, if those nodes are beneficial to the network, it will be more likely to succeed and reproduce again, passing on the extra brain boost.

The researchers assigned two different games for these networks to play, each an analogy for different social interactions. One, called the Prisoner's Dilemma, puts its participants in a scenario where cooperation is best for both parties but they still may be motivated to freeload. In the scenario, two suspects have been arrested for a crime. The police offer both a deal: Snitch on your partner and we'll give both of you a medium-length sentence. If you don't snitch, we'll easily convict you for a lesser crime, and you'll have to spend at least a little time in jail. But if you don't snitch and the other prisoner does, you're taking the fall ? and you'll be in prison for a long time.

It's best for both parties to keep quiet, but each may be tempted to take the risk of snitching and hoping their partner is more noble.

In a second scenario, the snowdrift game, two partners have to work together to dig out of a snowdrift. The best choice from the point of view of one partner is to let the other do all the digging. But if both partners choose this route, neither is will get out of the snowdrift.?

Artificial neural networks don't understand prisons or snowdrifts, of course, but they can be made to mathematically "play" these games, with winners getting a numerical payoff for avoiding a prison sentence or digging out of the snow. McNally and his colleagues set up 10 experiments in which 50,000 generations of neural networks got to work out these games. Intelligence was measured by the number of nodes added in each network as the players evolved over time. [10 Ways to Keep Your Mind Sharp]

Artificial brain boom
The simulations proved quite good at both the Prisoner's Dilemma and the snowdrift game, McNally said. They evolved strategies just like those seen when humans play these games with other humans.
