Solar Charger Juices Your Gadgets, Rain or Shine

It's an unavoidable fact of life: Your gadgets need juice —like a preacher needs pain, like thunder needs rain. (Thank you, Bono.) And when it comes to portable power-ups, our new favorite flavor is Orange.

The Joos Orange solar charger is the physical manifestation of simplicity. It's rugged, easy to store and carry, and (most importantly) quick to bestow a watt or two whenever you need it. Simply choose the correct adapter (the Orange comes with seven of the most popular ones), plug in your depleted phone or DS into the charger and let the life-giving juice flow. Yep, that's it.

Weighing in at a pound-and-a-half, the Orange is roughly the same size and weight as an iPad —and arguably a lot more useful. It can be completely submersed in water, dropped, kicked, and, in general, take the worst abuse man or nature can dish out.

Nestled inside its durable polycarbonate shell is a super-efficient 5,400-milliamp-hour replaceable lithium-ion battery capable of holding its charge for years. In our tests, we managed to dole out four full charges to a completely depleted iPhone before the Orange needed a solar recharge. It even fully charged the notoriously fickle iPad.

While PC owners will be able to download a standalone GUI for precise power metrics, the unit also has two LED status lights on the sides: one solar light (red) and other for the battery (green). When the Orange is running, the red light will blink rapidly to let you know you're getting juiced. Similarly, the green light spits out one blink for every 20 percent of the battery that's full. Four blinks and you know you have a battery that's between 60 and 80 percent full. Even better: the Orange comes with a pair of attachable reflectors that help collect somewhere between 20-30 percent more power when affixed to both ends.

No sun? No problem. While our test model wasn't equipped to charge efficiently by USB, the folks at Solar Components assured us that production models can be refilled at the standard USB charging rate (500 milliamps at 5 volts or 2.5 watts).

So go ahead and leave those outlets. Sucking down solar power has never been easier.

WIRED Cheap. Crazy-durable. Comes with nearly all connector tips you'll need for your mobile gear (you can order specific ones from Solar Components if not). Two screw-in mirror panels beef up charging efficiency by 30 percent. Nuclear fallout blot out the sun? Charge up by USB.
TIRED No Mac compatibility for GUI software. Deciphering the LED takes some getting used to. Screws for attachable mirrors are not ideal and are easily lost.

Brain Games Won't Make You Smarter, Study Says

Brain Games Won't Make You Smarter, Study <br /> Says

Brain training games do not make you smarter - FACT


"Brain games" are certainly fun, but contrary to what many players hope, they're not likely to make you any smarter. From a six-week study paid for by the BBC and reported by Discovery News:

More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills for at least 10 minutes a day, three times a week.
They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet and answering general knowledge questions.
Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.
Some brain-game manufacturers argued with the studies results, claiming that the findings didn't apply to their games. Whether or not the results of that study are on the money, professor of psychology from the University of Illinois Art Kramer points out: "There is precious little evidence to suggest the skills used in these games transfer to the real world."

It's not all bad news, though. For starters, regular mental exercise may increase your life expectancy. If you're really looking for some brain-boosting benefits, physical exercise is an extremely effective way to exercise your mind—and you're killing two birds with one stone.

Brain games may not make you smarter

LONDON: People playing computer games to train their brains might as well be playing Super Mario, new research suggests.

In a six-week study, experts found people who played online games designed to improve their cognitive skills didn’t get any smarter.

Researchers recruited participants from viewers of the BBC’s science show Bang Goes the Theory. More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills for at least 10 minutes a day, three times a week.

They were compared to more than 2,700 people who didn’t play any brain games, but spent a similar amount of time surfing the Internet and answering general knowledge questions. All participants were given a sort of I.Q. test before and after the experiment.

Researchers said the people who did the brain training didn’t do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.

The study was paid for by the BBC and published online yesterday by the journal Nature.
“If you’re (playing these games) because they’re fun, that’s absolutely fine,” said Adrian Owen, assistant director of the Cognition and Brain Sciences unit at Britain’s Medical Research Council, the study’s lead author.

“But if you’re expecting (these games) to improve your I.Q., our data suggests this isn’t the case,” he said during a press briefing.

One maker of brain games said the BBC study did not apply to its products. Steve Aldrich, CEO of Posit Science, said the company’s games, some of which were funded in part by the US National Institutes of Health, have been proven to boost brain power.

“Their conclusion would be like saying, ‘I cannot run a mile in under four minutes and therefore it is impossible to do so,” Aldrich said.

Posit Science has published research in journals including the Proceedings of the National Academy of Sciences showing their games improved memory in older people.

Small effects, Small difference

Computer games available online and marketed by companies like Nintendo that supposedly enhance memory, reasoning and other cognitive skills are played by millions of people worldwide, though few studies have examined if the games work.


“There is precious little evidence to suggest the skills used in these games transfer to the real world,” said Art Kramer, a professor of psychology and neuroscience at the University of Illinois. He was not linked to the study and has no ties to any companies that make brain training games.

Kramer had several reservations about the BBC study’s methodology and said some brain games had small effects in improving people’s cognitive skills.

“Learning is very specific,” he said. “Unless the component you are trained in actually exists in the real world, any transfer will be pretty minimal.”

Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can spark new connections between neurons and produce new brain cells. “Fitness changes the building blocks of the brain’s structure,” he said.

Still, Kramer said some brain training games worked better than others. He said some games made by Posit Science had shown modest benefits, including improved memory in older people.

Difficulty levels matter

Other experts said brain games might be useful, but only if they weren’t fun.

“If you set the level for these games to a very high level where you don’t get the answers very often and it really annoys you, then it may be useful,” said Philip Adey, an emeritus professor of psychology and neuroscience at King’s College in London.

If people are enjoying the brain games, Adey said they probably aren’t being challenged and might as well be playing a regular videogame.

He said people should consider learning a new language or sport if they really wanted to improve their brain power. “To stimulate the intellect, you need a real challenge,” Adey said, adding computer games were not an easy shortcut. “Getting smart is hard work.” — AP
