A new technique to make drugs more soluble

Before Ibuprofen can relieve your headache, it has to dissolve in your bloodstream. The problem is Ibuprofen, in its native form, isn’t particularly soluble. Its rigid, crystalline structures — the molecules are lined up like soldiers at roll call — make it hard to dissolve in the bloodstream. To overcome this, manufacturers use chemical additives to increase the solubility of Ibuprofen and many other drugs, but those additives also increase cost and complexity.

Supercomputers enlisted to shed light on photosynthesis

Researchers are using high-performance computing to simulate the processes that take place during the first moments of photosynthesis. Using quantum mechanics as the basis, computer scientists, physicists and chemists are working together to produce simulations of the molecule in which photosynthesis occurs.

Microscopic fish are 3-D-printed to do more than swim: Researchers demonstrate a novel method to build microscopic robots with complex shapes and functionalities

Nanoengineers at the University of California, San Diego used an innovative 3-D printing technology they developed to manufacture multipurpose fish-shaped microrobots — called microfish — that swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled. These proof-of-concept synthetic microfish will inspire a new generation of ‘smart’ microrobots that have diverse capabilities such as detoxification, sensing and directed drug delivery, researchers said.

Another milestone in hybrid artificial photosynthesis

Researchers using a bioinorganic hybrid approach to artificial photosynthesis have combined semiconducting nanowires with select microbes to create a system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.
