The Unix Changelog lists a multitude of upgrades and new features. The most interesting of these, in my opinion, is Speed Dial, which lets you set up to nine default websites in a "number pad" type of arrangement, which will then show up every time a new tab is opened, along with the search bar of your preferred search engine. This allows easier access to frequented sites and searches. Keyboard shortcuts have also been mapped for each Speed Dial entry (Ctrl + 0-9). Of course, if you dislike the new funtionality, Speed Dial can be hidden with the click of a link in the lower right-hand corner of the page. From a day's worth of use, 9.20 seems even snappier than earlier versions, and is probably well worth the upgrade."

The Register reports that a theory has been supplied, by researchers at Imperial College and Duke University, which suggests that an "Invisibility Cloak" could be created, with help from nanotechnology. From the article:
"The idea is that we now have technology to manipulate the surface of metamaterials on the nano scale, meaning light can be directed very precisely around an object, making it imperceptible to an observer. Researchers at Imperial College and Duke University did the sums, and found that an invisibility cloak should be possible."
