This video illustrates the powerful implications of six key technologies: 3D printing, robotics, artificial intelligence, the “Internet of Things,” infinite computing and synthetic biology.

Can Video Games Make You Smarter?

February 4, 2014

What are the effect of video games on our brains? Well, first off, there’s a big difference between a few rounds of Super Mario Bros. after your homework is done, and staying up all night and all day eating Cheetos and sinking deeper into the world of gaming. The latest research shows that moderate gaming has beneficial effects that target specific areas of the brain, as AsapSCIENCE explains. To get the full effect, you also have to get enough physical exercise, social connections, and education -in other words, a well-rounded life. Once you have your priorities in order, enjoy those games!

Colour printing reaches its ultimate resolution

January 9, 2013

The highest possible resolution images — about 100,000 dots per inch — have been achieved, and in full-colour, with a printing method that uses tiny pillars a few tens of nanometres tall. The method could be used to print tiny watermarks or secret messages for security purposes, and to make high-density data-storage discs.

Each pixel in these ultra-resolution images is made up of four nanoscale posts capped with silver and gold nanodisks. By varying the diameters of the structures (which are tens of nanometres) and the spaces between them, it’s possible to control what colour of light they reflect. Learn more here.

The Exact Date When Our Computer World Ends

December 28, 2012

The world didn’t end last Friday December 21, 2012 just like the world didn’t end in the year 2000, with failing computers deleting bank accounts and crashing aeroplanes. That doesn’t mean the world isn’t going to end. It will. And if we keep our current operating systems, this is the exact date when all goes poof: 15:30:08 UTC on December 4th of the Year 292,277,026,596.

That’s when the Unix time stamp will exceed the largest value that can be held in a signed 64-bit integer. Unix is what powers most of the computing systems that are vital for human life on Earth, from banks to medical life support systems to electric grids to satellites to the internet. And your iPhone and Android phone too.

Of course, none of our computers today will ever reach the year 292,277,026,596. Mainly because Earth may not be around by then. The Sun would have destroyed it about 7,900,000,000 years from now. That’s when our home star will reach its maximum diameter as a Red Dwarf, destroying Mercury, Venus and, most probably, Earth.

Not that you or I will be around to see any of this, anyway. Learn more here – Timeline of the Far Future.

DNA: The Ultimate Hard Drive

October 29, 2012

When it comes to storing information, hard drives don’t hold a candle to DNA. Our genetic code packs billions of gigabytes into a single gram. A mere milligram of the molecule could encode the complete text of every book in the Library of Congress and have plenty of room to spare. All of this has been mostly theoretical—until now. In a new study, researchers stored an entire genetics textbook in less than a picogram of DNA—one trillionth of a gram—an advance that could revolutionize our ability to save data.

The scientists encoded the 53,400-word book, 11 JPG images and a JavaScript program – amounting to 5.27 million bits of data in total – into sequences of DNA. If they were able to upscale the process this would equate to 5.5 petabits of data — around 700 terabytes — in a single gram of DNA.

Just think about it for a moment: One gram of DNA can store 700 terabytes of data. That’s 14,000 50-gigabyte Blu-ray discs… in a droplet of DNA that would fit on the tip of your pinky. To store the same kind of data on hard drives — the densest storage medium in use today — you’d need 233 3TB drives, weighing a total of 151 kilos. Learn more here, here, here or here.

Rubik’s Cube world record

September 24, 2012

A robot called CubeStormer II solves the Rubik’s Cube puzzle faster than the human world record. See:

The mechanics are constructed entirely from LEGO, including four MINDSTORMS NXT kits, with the addition of a Samsung Galaxy S II smartphone running a custom Android app as the robot’s brain.

SMSing does not affect children’s use of grammar

September 10, 2012

Children who use ‘text speak’ when sending messages on their mobile phones do not have a poor grasp of grammar, a study has shown.

Researcher assessed the spelling, grammar, understanding of English and IQ of primary and secondary schoolchildren and compared those skills with a sample of their text messages.

There was no evidence of any significant relationships between poor grammar in text messages and their understanding of written or spoken grammar.

The results will reassure parents who may have feared that text speak was eroding their child’s grasp of English. Learn more here.
