The motion of the medium matters for self-assembling particles

Earlier work assumed that the liquid medium in which certain self-assembling particles float could be treated as a placid vacuum, but scientists have now shown that fluid dynamics play a crucial role in the kind and quality of the structures that can be made in this way.

Scientists use DNA to shape graphene into the transistor of the future

graphene 2

Increasingly, quantum computers are predicted to be the next great leap in computational power — but in reality they are more likely to be the next next great leap. Right now we have to tailor experimental quantum chips to their particular mathematical process of interest, literally build them to solve a specific problem; today’s silicon solutions will reach the peak of their potential long before we can go buy Intel or AMD’s new plug-and-play quantum processor.

Engineers invent programming language to build synthetic DNA

1 uwengineersi

Similar to using Python or Java to write code for a computer, chemists soon could be able to use a structured set of instructions to “program” how DNA molecules interact in a test tube or cell.
A team led by the University of Washington has developed a programming language for chemistry that it hopes will streamline efforts to design a network that can guide the behavior of chemical-reaction mixtures in the same way that embedded electronic controllers guide cars, robots and other devices.

DNA puts Stanford chemists on scent of better artificial nose

A new approach to building an “artificial nose” – using fluorescent compounds and DNA – could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists. If their method lives up to its promise, it could one day detect everything from incipiently souring milk to high explosives.
