Roam2Conformation Roam2     Picture: Inga HendricksonScoop FOR: Budget-conscious shooters. THE Essay: At 5.4 ounces, the Roam2 was the lightest of the clustering. It can film 30 fps at 1280p (or 60 fps at 720p), and its sliding toggle was refreshfully soft to manoeuvre with or without expectant ski gloves on, devising this the better multi-season camera in the mix. Its fisheye lense and mountain splay 270 degrees—sufficiency that you can cinema arse you. We besides loved that it has a integral laser: when you jam a release, a beam shoots where the camera is pointing. It comes Read more [...]

The rotor is made of two turns of DNA

A group of Japanese scientists has designed nanomotors working by changing the conformation of the DNA molecule - the transition from the double helix pravozakruchennoy (B-form) in the left-twisted (Z-form). "Run" is the motor by changing the concentration of ions in solution. Securing the motor in a rigid frame that fixes it to the substrate, not interfering with the rotation of the rotor, the scientists managed by atomic force microscopy to monitor the operation of the engine in real time. They fixed two turns of the rotor, which is one BZ-transition.Fig. 1. Top: scheme of rotation Read more [...]
