r00tyroot writes with news that slipped by yesterday, quoting from the Internet Systems Consortium's release: "ISC joined other key participants of the Internet technical community in celebrating the achievement of a significant milestone for the Domain Name System today as the root zone was digitally signed for the first time. This marked the deployment of the DNS Security Extensions (DNSSEC) at the top level of the DNS hierarchy and ushers the way forward for further roll-out of DNSSEC in the top level domains and DNS Service Providers."

grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

Arvisp writes "According to a blog post by former Google China president Kai-Fu Lee, Apple plans to produce nearly 10 million tablets in the still-unannounced product's first year. If Lee's blog post is to be believed, Apple plans to sell nearly twice as many tablets as it did iPhones in the product's first year."

eldavojohn writes "Okay, well, maybe not everyone but more than twenty companies (including Apple, Qualcomm, Motorola and Microsoft) are being sued for a generic patent that reads: 'Apparatus and methods for controlling a portable electronic device, such as an MP3 player; portable radio, voice recorder, or portable CD player are disclosed. A touchpad is mounted on the housing of the device, and a user enters commands by tracing patterns with his finger on a surface of the touchpad. No immediate visual feedback is provided as a command pattern is traced, and the user does not need to view the device to enter commands.' Sounds like their may be a few companies using that technology. The suit was filed on July 15th in the favoritest place ever to file patent claim lawsuits: Texas Eastern District Court. It's a pretty classic patent troll; they've been holding this patent since 2003 and they just noticed now that everyone and his dog are using touchpads to control portable electronic devices."

According to scientists, city Great Tits prefer other city Great Tits over country Great Tits. (Lets act like adults). The researchers found that the city dwellers responded more strongly to songs of fellow city dwellers and the same held true for the bumpkins. The average minimum pitch of male Great Tit songs in noisy urban areas was higher than in quieter, rural areas just a few miles away. Dr Rupert Marshall, of Aberystwyth University, Wales, and his team recorded bird song in 20 different cities in Britain. He says, "People speak louder and higher in noisy places like pubs and bars but still recognise their friends' voices once they go outside. Great tits seem to learn the high notes from their neighbours but don't respond as strongly to lower rural tones even when it's quiet."

It turns out that space tastes like raspberries and not Tang or freeze-dried ice cream as one might suspect. Scientists at the Max Planck Institute for Radio Astronomy were searching for evidence of amino acids in space when they found ethyl formate, the chemical used in to make raspberry flavoring. The astronomers used the IRAM telescope in Spain to analyze electromagnetic radiation emitted by a hot and dense region of Sagittarius B2 that surrounds a newborn star. Astronomer Arnaud Belloche said, "It [ethyl formate] does happen to give raspberries their flavour, but there are many other molecules that are needed to make space raspberries."
