The purpose of Math Fractions: Multiplication & Division is to make the process of learning fractions as fun as possible for children who have been weaned on video games and electronic devices for the last decade. The app as a whole does a fine job of turning learning into an engaging game and ensuring there are apt rewards in place for a job well done.

The app is designed to thoroughly involve a young child in the process of learning fractions. It does this by first asking them to create an avatar and dress them for integration into this game … Read more

Times Tables Game does a good job of tapping into many of the things that make a good educational app for the iPad, but it is missing some very important components. Due to a limited trial, sometimes messy interface, and convoluted menu system, it works best when a parent directly oversees play by the child.

Times Tables Game is designed to help children learn their times tables in a colorful, easy-to-use interface. With animals, lots of bright colors, and flowers onscreen, combined with light animations, the app is pleasant to look at, though it can get busy and the directions … Read more

Math assignments can be dull and most children would rather play video games or watch movies. With Math: Decimals Multiplication, they can finally do at least one of those while practicing their math homework, and the results are pretty good.

There is some setup involved, so you might need to lend a helping hand as the game starts up. First, they enter a name, before choosing an avatar and outfit for that avatar. From there, they are asked to complete a short warm-up exam, and then the games unlock. The games are unique and thematic, though the actual math is … Read more

Our body tissue, not to mention diseases, each have their own unique "fingerprint," which can in turn be examined to diagnose various health issues at very early stages.

Now, researchers at Case Western Reserve University in Cleveland say that after a decade of work they've developed a new MRI (magnetic resonance imagining) technique that can scan for those diseases very quickly. In just 12 seconds, for instance, it may be possible to differentiate white from gray matter in cerebrospinal fluid in the brain; in a matter of minutes, a full-body scan would provide far more data, making diagnostics considerably easier and less expensive than today's scans.… Read more

Oxford University Ph.D. student Jessica Richman, who today finished raising some $350,000 from more than 2,500 people wanting to take part in the uBiome project, isn't shying away from reality: "Yes, we are going to be sampling people's poo," she told the Guardian this week.

And for the squeamish, she offered an asterisk: "You'll only have to wipe it on the toilet paper."

The uBiome project is a "citizen science" effort to sequence the genomes of the trillions of bacteria that colonize our bodies and likely play pivotal … Read more

AVI has been around a long time, and there's a lot of video saved in the format. Some devices, including mobile devices, have limited media file compatibility and won't play AVIs. For many users, the simplest solution is to convert the AVI files to MP4 files. AVI to MP4 Converter from A Software Plus is a free utility that can do the job with a minimum of fuss. It converts AVI and similar formats like DivX and Xvid, singly or in batches. We tried it in Windows 7 Home Premium SP1.

AVI to MP4 Converter's user interface … Read more

The new MacBook Pro with Retina display has many noteworthy features, from a unique 2,880x1,800-pixel screen to new Nvidia graphics to large SSD storage options. But, the most surprising may be the multiple video outputs -- something not seen on a MacBook before now.

The last several generations of MacBook have had either a mini-DisplayPort or combo Thunderbolt/DisplayPort jack. HDMI has been on our most-wished-for lists for years, so Apple finally adding HDMI (which is found on pretty every other current laptop) is a big move, especially when combined with a second Thunderbolt port.

The initial review of the Retina Pro … Read more
