Enabling Auto Spelling Correction in Snow Leopard

In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.

Unthrifty Loveliness: Shakespeare Sonnets Encoded in DNA at $12,400 per Megabyte

Send Article to a Friend

Ewan Birney and Nick Goldman, two scientists from the European Bioinformatics Institute, have worked out a system to encode text, audio, and other data in DNA. Teaming up with Aligent Technologies, the two encoded all of Shakespeare’s sonnets, an audio clip of Martin Luther King Jr. speaking, and a photograph into a synthesized DNA sample. Though Aligent did the DNA synthesizing work for free, the cost of the DNA synthesis is estimated to have been roughly $12,400 per megabyte. Luckily, prices for DNA synthesis are dropping, and it is estimated that 50 billion megabytes of text, roughly equivalent to everything ever written by humans, could be encoded into a sample that would weigh less than “a granola bar.” This takes the idea of cloning your data to an entirely new level.favicon follow link
