Caltech Scientists Use DNA Tiles To Play Tic-Tac-Toe at the Nanoscale

An anonymous reader shares a report: An innovation at Caltech allows scientists to play a virtual "tic-tac-toe" game with individual strands of DNA, providing a new way to experiment with DNA sequencing and create custom patterns. According to ArsTechnica, the technique was dubbed "DNA Origami [paper; PDF]" by its creator Lulu Qian and is considered by Caltech fellows to be a "huge advancement" in the field of nanotechnology (manipulation of particles on a minute, atomic scale).

      I don't care, for me my algae strawberry steak, I grow in my own kitchen aquarium is getting closer day by day. Genetically engineering old world crops is just plain stupid and a waste of time. GMO algae, any food imaginable food product created and grown really fast (just designed texture, consistency, nutrients, flavours and trace element profile), is the only way to go.

    Grow up, APK. You're obsessed with ArsTechnica and Thor Schrock after well over a decade. No one else uses the word "ArseholeTechnica" other than you, which gives you away. If you're so concerned that an ArsTechnica article was cited, go find a Caltech press release, conference proceeding, or journal paper, for yourself. The truth is that you're spamming Slashdot today because you want revenge on whipslash. It's been two years since he pledged to limit your spam, yet you're still obsessed. You'll probably still be complaining about it two decades later, just like you're still obsessed with ArsTechnica. Seek professional help.

    APK stopped signing his posts because he's hiding from whipslash. Slashdot has been deleting APK's posts and doing an effective job at limiting his spam. APK is hiding from whipslash, despite promising that he'd be relentlessly crapflooding Slashdot today. He's reduced to a few stupid posts and hiding by not signing most of them, like the chickenshit weasel he is. It's clear that whipslash has defeated and utterly humiliated APK once again.
