    It's a cliché to say that clothes reflect who you are... but in this case, it's definitely true. Dot One is offering a lambswool scarf (among other products) whose artwork is based on your genetic sequence. All you do is send in a 23andMe-style cheek swab sample that's scanned for pieces of distinctive yet repeatable genetic code. When Dot One matches that code to colors, the result is a scarf pattern that looks reasonably fashionable, but is almost certain to be unique -- unless you're an identical twin, the odds of running into someone else with the same scarf are virtually zero.

  • Max Planck Institute sequences genome of Siberian girl from 80,000 years ago, smashes DNA barriers

    We've known little of the genetic sequences of our precursors, despite having found many examples of their remains: the requirement for two strands in traditional DNA sequencing isn't much help when we're usually thankful to get just one. The Max Planck Institute has devised a new, single-strand technique that may very well fill in the complete picture. Binding specific molecules to a strand, so enzymes can copy the sequence, has let researchers make at least one pass over 99.9 percent of the genome of a Siberian girl from roughly 80,000 years ago -- giving science the most complete genetic picture of any human ancestor to date, all from the one bone you see above. The gene map tells us that the brown-skinned, brown-eyed, brown-haired girl was part of a splinter population known as the Denisovans that sat in between Neanderthals and ourselves, having forked the family tree hundreds of thousands of years before today. It also shows that there's a small trace of Denisovans and their Neanderthal roots in modern East Asia, which we would never have known just by staring at fossils. Future discoveries could take years to leave an impact, but MPI may have just opened the floodgates of knowledge for our collective history.

  • MinION USB stick decodes DNA in a matter of seconds

    If you happen to be "special," then this $900 USB device is just about the worst thing ever. The aptly named MINion serves its masters by interrogating the cells of living organisms and rooting out their genetic secrets. We won't pretend to know exactly how it works, but it starts by pulling a strand of DNA through a razor-like nanotube that unzips the double helix. The nucleotide bases are then electrocuted one by one until they give up their code. The resulting sequence is stored like a ticker-tape readout, for the whole world to see. The MinION can complete its task in seconds and, unlike most other DNA sequencers, it's portable and simply plugs into a laptop. Luckily, it has so far only been shown to work on very short genomes, like those belonging viruses and bacteria, so for now you're probably safe.
