New carbon nanotube aerogel is now the world's lightest solid material
Frozen smoke (read: aerogel) -- not to be confused with the stuff your Grandma uses to flavor her turkey -- is the world's lightest solid material, and it just keeps getting lighter. Researchers at the University of Central Florida have created a new form of the super material, known as multi-walled carbon nanotube (MWCNT) aerogel, that has a density of just four milligrams per cubic centimeter and can be used in sensors to detect pollutants and toxic substances, chemical reactors, and electronic components. Aerogels, which are known as the world's most effective insulators, have been around since the early 20th century, but most of these are fabricated from silicon dioxide. In order to produce the new aerogel, researchers removed the liquid from a "wet gel of well-dispersed pristine MWCNTs," creating a honeycomb structure with walls just 100-nanometers thick. The resulting material is an impressive and resilient electrical conductor that looks and acts less like frozen smoke and more like a burnt marshmallow. And now, you know.

Blood Sport: Moving out of the fire -- in PvP?
Listening Music: All is Full of Love, by Bjork. Icelandic Fantastic! I don't even know a third of what this video is about, though. Last Week: We talked some Ring of Valor problems and solutions. This Week: This is kind of like Ring of Valor part II, kind of not. I wanted to talk about PvE elements in PvP a bit more. I dunno, it's a weird article. You've been warned. Onto the show... "Don't stand in the fire, noob!" That's really what skill is, right? In the many years I've been playing WoW, I think every guild application I've filled out, I've scribbled "I can move out of fire" somewhere on it. Now if I actually could move out of the fire is an entirely different question, but hey, whatever helps me get accepted, right? Some guilds even have a humorous section devoted to asking the applicant questions like... "Can you move out of fire?" "Can you do a good Chewbacca impression?" "Can you put out more dps than the tank?" "Am I pretty in pink?" So why am I writing about guild applications? This is the arena column. This isn't PvE! Well, arena has become more like PvE than you might have originally thought. Don't write me off just yet!
