HDTV: even Octopuses prefer it

It's the frame rate that adds reality, scientists decide.

An octopus, yesterday.

An octopus, yesterday.

Apparently we aren't the only species to prefer the crisp, smooth picture of an HDTV compared to that from one of those old CRT sets of yesteryear.

A follow-up study of octopus behavior by the Journal of Experimental Biology shows that mollusks react to high-definition videos where they used to be nonresponsive to movies on a SD set.

Renata Pronk and colleagues from Macquarie University, Australia, decided to see if using an LCD display and HD video would fix the long-time problem.

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.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
