How To Make Yourself Smarter

If
you do lots of push-ups, you get stronger – but if you do a lot of mental
exercises, do you get smarter?

For most of human history, it’s accepted that you’re either born smart
or (sadly) not and that there’s no amount of Sudoku that will make you
smarter (sure you can be more knowledgable – say by educating yourself,
but not intrinsically more intelligent).

But that common wisdom may be wrong: studies show that you can increase
your smarts by improving your memory through certain types of games.

… in 2008, [Susan] Jaeggi turned one of these tests of working
memory into a training task for building it up, in the same way that
push-ups can be used both as a measure of physical fitness and as a
strength-building task. “We see attention and working memory as
the cardiovascular function of the brain,” Jaeggi says.“If
you train your attention and working memory, you increase your basic
cognitive skills that help you for many different complex tasks.”

Jaeggi’s study has been widely influential. Since its publication,
others have achieved results similar to Jaeggi’s not only in elementary-school
children but also in preschoolers, college students and the elderly.
The training tasks generally require only 15 to 25 minutes of work per
day, five days a week, and have been found to improve scores on tests
of fluid intelligence in as little as four weeks. Follow-up studies
linking that improvement to real-world gains in schooling and job performance
are just getting under way. But already, people with disorders including
attention-deficit hyperactivity disorder (A.D.H.D.) and traumatic brain
injury have seen benefits from training. Gains can persist for up to
eight months after treatment.

Helium-filled floating wind turbine, renewable energy with style

Helium-filled floating wind turbine, renewable energy with style

There’s no doubting that the cause of renewable energy is a noble one. But, ethics aside, it also gives birth to the occasional technical marvel. Altaeros Energies, a company from Massachusetts (with MIT and Harvard blood in its veins) has created one such curiosity. The prototype is a wind-turbine that doesn’t just languish on a hill-top, cutting a line in the horizon. No, this one has a helium-filled outer-section which allows it to deploy itself to 1,000 feet, where it can benefit from stronger, more consistent winds and gives nearly twice the power yields of its land bound brethren. That’s all very nice, but we just thought it looked dang cool in action.

Anonymous, People's Liberation Front Build Anonymous Data-Sharing Site


suraj.sun writes with these snippets from an article at Ars Technica: “Hacker group Anonymous and the People’s Liberation Front have created a data-sharing site called AnonPaste.tk, meant to host pastes of code and other messages without any moderation or censorship of the information posted. The new site, which uses a free .tk web address, allows users to set a time for the paste to expire. It claims that data is encrypted and decrypted in the browser using 256 bit AES, so the server doesn’t see any of the information included in the paste.The site says it’s taking donations in the form of WePay or BitCoins. … AnonPaste is built using open-source software called ZeroBin, created by French developer Sebastien Sauvage. According to Infoweek Sauvage has experience in creating online authentication systems for French banks, suggesting the creator knows a thing or two about encryption of data. Still, on the software’s information page, Sauvage reminds potential users that ZeroBin software can not protect against potential Javascript attacks. ‘Users still have to trust the server regarding the respect of their privacy,’ he says. ‘ZeroBin won’t protect the users against malicious servers.'”

US Charges English Twins Over $1.2m 'Stock Robot' Fraud

peetm writes “Twin brothers from England face US civil charges for allegedly defrauding investors out of $1.2m (£745,000) through a bogus stock-picking robot. The twins; Alexander and Thomas Hunter; were just 16 years old when they devised the scam — which fooled around 75,000 people, according to U.S. officials.”
