By pinching areas within the camera’s view you section off ovals which you can use to rotate and move around the display, and the researcher said more gestures are being worked on”

Scientists have written a message into the DNA of a living organism, a breakthrough they believe could lead to a new era of organic computers capable of healing themselves if damaged. The researchers encoded Einstein’s most famous equation and most prolific year into the genome of one the hardiest strains of bacteria in the world, Bacillus subtilis. The characters “E=MC^2 1905!” were then read from the bacterium at a later date by analysing its genetic sequence.

We have used this on-line tool for quite some time now, and although it can be a little slow at times, it is a decent method for checking many different guidelines all at once.
