I just read this in Nature:
The researchers designed the structure of the nanorobots using open-source software, called Cadnano, developed by one of the authors — Shawn Douglas, a biophysicist at Harvard"s Wyss Institute for Biologically Inspired Engineering. They then built the bots using DNA origami. The barrel-shaped devices, each about 35 nanometres in diameter, contain 12 sites on the inside for attaching payload molecules and two positions on the outside for attaching aptamers, short nucleotide strands with special sequences for recognizing molecules on the target cell. The aptamers act as clasps: once both have found their target, they spring open the device to release the payload.
These robots may be able to identify and target cancer cells.

However, it’s important to adhere to the App Store Review Guidelines and avoid sending users unsolicited messages or spam as notifications. Doing so not only takes away from the user experience, but may cause your app to be removed from the App Store.

Once you build a great app, you want everyone to know about it. However, when you promote your app, you should avoid using services that advertise or guarantee top placement in App Store charts. Even if you are not personally engaged in manipulating App Store chart rankings or user reviews, employing services that do so on your behalf may result in the loss of your Apple Developer Program membership. Get helpful tips and resources on marketing your apps the right way from the App Store Resource Center.

The Open Source Initiative is switching to a member-led governance. For that, it will need members.
The OSI Board would be very grateful if you would complete the totally anonymous survey which will help us understand what attributes you would like from OSI membership in the future. Thanks for your help!
