Scientists have discovered that humans aren’t the only species that dig the high-definition picture quality of modern HDTVs. Renata Pronk and colleagues from Macquarie University, Australia have studied the behavior of octopuses when they are shown images in HDTVs, and have observed that the mollusks react to high-definition videos where they used to be nonresponsive to movies on a SD set.
In 2008, Pronk theorized the difference ultimately came down to the frame-rate, not image quality (at the time one in five HDTV owners couldn’t tell the difference between HD and SD programming.) She said that standard definition video probably seemed more like a series of still images instead of a real object.
When a 50-frames-per-second, progressive-scan clip of a “tasty crab” was shown to an octopus caught from Sydney Harbor it reacted to the image like it was the real deal.
“The octopus jetted towards the screen and tried to catch the crab and eat it,” Pronk says in the article from the Journal of Experimental Biology.
Unfortunately for the octopus, the crab was in fact not tasty nor real.
Hopefully Pronk is working up a new test so octopuses can tell us if it’s worth it to fork out extra cash for a 240 hertz set, or if we’re better off saving with a 120 hertz model.

Microsoft has been pursuing Motorola for quite some time in courts. The reason was that Microsoft alleged Motorola infringed one of its patents by including certain texting features in its smartphones.

Google has been steadily working on its Project Glass and the prototype glasses from the project are being tested publicly by a number of Google personnel. While many have cast doubts as to whether or not these prototypes are fully functional and operate on their own, Google seems quite confident of the progress. The search giant has now unveiled the first video samples from the project.
Apple’s Siri has been lauded as one of the best voice-enabled personal assistants available. Although Siri is quite good, it is not perfect and does make mistakes. And now, Siri has a worthy contender in the form of S Voice, the voice assistant that Samsung unveiled to be a part of Samsung Galaxy S III. Galaxy S III will soon be in the hands of the consumers and S Voice will be pitted against Siri. Here’s a fairly accurate comparison of the two.
Dell has taken a great liking to Windows 8 and Dell personnel have proclaimed publicly that they may be going forward with Windows 8 tablets. While currently, Dell is not at all a success in the tablet market, it is hoping to leverage some advantage with the great interface Windows 8 has to offer. Two images have now surfaced on the web, allegedly of Windows 8 tablets from Dell.
