BraveHeart writes "Researchers have long known that mammals, including humans, lack a key enzyme — one possessed by most of the animal kingdom and even plants — that reverses severe sun damage. For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA. 'Normal sunscreen lotions convert UV light to heat, or reflect it away from our skin. A sunscreen containing photolyase could potentially heal some of the damage from UV rays that get through.'"

ChrisPaget writes "I'm planning a pretty significant demonstration of GSM insecurity at Defcon next week, where I'll intercept and record cellular calls made by my attendees, live on-stage, no user-input required. As you can imagine, intercepting cellphones is a Very Big Deal in the eyes of the law; this blog post is an attempt to reassure everyone that their privacy is being taken seriously despite the nature of the demo. I'm not just making it up either — the EFF have helped significantly with the details."

War, earthquakes, and broken washers are all unavoidable events for which a carrier should not be liable if travel is delayed according to Southwest Airlines. Southwest quietly updated their act of God list a few weeks ago to include mechanical problems with the other horrors of an angry travel god. From the article: "Robert Mann, an airline industry analyst based in Port Washington, NY, called it 'surprising' that Southwest, which has a reputation for stellar customer service, would make a change that puts passengers at a legal disadvantage if an aircraft breakdown delays their travel. Keeping a fleet mechanically sound 'is certainly within the control of any airline,' Mann said. 'Putting mechanical issues in the same category as an act of God — I don't think that's what God intended.'"
