Ever get the urge to look at pornographic drawings of famous cartoon children? Neither do I, but 28-year-old Kurt James Milner did, and that's what got him registered as a sex offender. Police received a tip about the pornographic material and eventually found images featuring child characters from The Simpsons and The Powerpuff Girls on Milner's computer. Back in 2008, a Supreme Court judge in Australia ruled that cartoons in which child characters engage in sexual acts is child pornography. Milner said he downloaded the images to show them to his friend 'because he believed they were funny.' Guess it's not so funny now.

KentuckyFC writes "Great things are expected of terahertz waves, the radiation in the electromagnetic spectrum between microwaves and the infrared. Terahertz waves pass through non-conducting materials such as clothes, paper, wood and brick and so cameras sensitive to them can peer inside envelopes, into living rooms and 'frisk' people at distance. That's not to mention the great potential they have in medical imaging. Because terahertz photons are not energetic enough to break chemical bonds or ionize electrons, it's easy to dismiss fears over their health effects. And yet the evidence is mixed: some studies have reported significant genetic damage while others, although similar, have reported none. Now a team led by Los Alamos National Labs thinks it knows why. They say that although the forces that terahertz waves exert on double-stranded DNA are tiny, in certain circumstances resonant effects can unzip the DNA strands, tearing them apart. This creates bubbles in the strands that can significantly interfere with processes such as gene expression and DNA replication. With terahertz scanners already appearing in airports and hospitals, the question that now urgently needs answering is what level of exposure is safe."

Several readers including erlehmann and tmk wrote to inform us about the dawning of Internet censorship in Germany under the usual guise of protecting the children. "This week, the two big political parties ruling Germany in a coalition held the final talks on their proposed Internet censorship scheme. DNS queries for sites on a list will be given fake answers that lead to a page with a stop sign. The list itself is maintained by the German federal police (Bundeskriminalamt). A protest movement has formed over the course of the last several months, and over 130K citizens have signed a petition protesting the law. Despite this, and despite criticism from all sides, the two parties sped up the process for the law to be signed on Thursday, June 18, 2009."
