ஆராய்ச்சியா​ளர்களையே அசர வைத்த கிளி


கொக்காற்றோ (Cockatoo) எனும் வகையைச் சார்ந்த கிளி ஒன்று தனக்காக சற்று தொலைவில் வைக்கப்பட்டிருந்த உணவை எடுப்பதற்காக குச்சி ஒன்றினை ஒடித்து அதனை பயன்படுத்தியுள்ளது.
ஐந்தறிவு ஜீவனான இந்தக் கிளியின் இச்செயற்பாடானது ஒக்ஸ்போர்ட் பல்கலைக்கழக ஆரய்ச்சியாளர்களையே வியக்க வைத்துள்ளதாம்.

iOS 7 vs iOS 6 – Side By Side Visual Comparison [IMAGES]

So, after much deliberation, rumor, concept and a little bit more rumor, Apple has finally shown the world what exactly Jony Ive’s vision of software design is with the introduction of iOS 7.

iOS 7 Features Walkthrough [VIDEO]

As I’m sure you’re aware, iOS 7 was officially announced by Apple yesterday at their annual  WWDC event  in San Francisco. There’s an enormous amount riding on this operating system release, as it’s their one big chance to prove themselves as the leader of the pack when it comes to mobile innovation.

A very large collection of new features were added to iOS, and you’ll be hard pressed in finding an app or panel that looks identical to iOS 6.
