Computer scientists at Caltech have designed DNA molecules that can carry out reprogrammable computations, for the first time creating so-called algorithmic self-assembly, in which the same "hardware" can be configured to run different "software." The system is analogous to a computer, but instead of using transistors and diodes, it uses molecules to represent a six-bit binary number as input, during computation, and as output.

Researchers at the National Institute of Standards and Technology have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable LEDs based on a simpler shell design.

Researchers from New York University have engineered nanoscale protein micelles capable of both delivering chemotherapeutic drugs and being tracked by magnetic resonance imaging (MRI). The innovation falls into the category of "theranostics," meaning that it combines diagnostic capability and drug delivery, allowing researchers to administer therapy while also non-invasively monitoring the therapeutic progress and drastically reducing the need for surgical intervention.

Physicists at the California Institute of Technology have designed a method that theoretically could levitate and propel objects using only light waves. The team believes that the method would lead to the development of a light-powered spacecraft that can travel to the nearest planet outside of the solar system.

Scientists have developed an approach to identify, quantify, and characterize titanium dioxide engineered nanoparticles found in surface waters, which paves the way for routine monitoring of engineered nanoparticles in the environment.
