mseeger writes "The German Federal Constitutional Court has ruled the country's current data retention law unconstitutional. All stored telephone and email communication data, previously kept for six months in case it was needed by law enforcement, now must be deleted as soon as possible. The court criticized the lack of data security and insufficient restrictions for access to the data. The president of the court said continuing to retain the data would 'cause a diffusely threatening feeling of being under observation that can diminish an unprejudiced perception of one's basic rights in many areas.' While it doesn't disallow data retention in general, the imposed restriction demands a complete reworking of the law." An anonymous reader contributes the Court's press release and more information on the ruling, both in German.

bLanark writes with news of a new substance that can be sprayed on for a durable, easy-to-clean film on almost any substance, hard or soft. The liquid glass is essentially pure silicon dioxide, and it goes on in a layer 15 to 30 atoms thick. It is breathable and flexible, but waterproof and resistant to bacterial growth. The patent is held by a German company, Nanopool, which is in discussion with many parties about a wide range of uses: keeping public spaces sanitary, keeping restaurants clean, and keeping cars or trains clean. "The spray forms a water-resistant layer, meaning it can be cleaned using only water. Trials by food-processing companies showed that sterile surfaces covered with a film of liquid glass were equally clean after a rinse with hot water as after their usual treatment with strong bleach."
