“We created three-dimensional, synthetic DNA-like crystals,” said UCLA chemistry and biochemistry professor Omar M. Yaghi, who is a member of the California NanoSystems Institute (CNSI) at UCLA and the UCLA–Department of Energy Institute of Genomics and Proteomics. “We have taken organic and inorganic units and combined them into a synthetic crystal which codes information in a DNA-like manner. It is by no means as sophisticated as DNA, but it is certainly new in chemistry and materials science.”
The discovery could lead to cleaner energy, including technology that factories and cars can use to capture carbon dioxide before it reaches the atmosphere.
“What we think this will be important for is potentially getting to a viable carbon dioxide–capture material with ultra-high selectivity,” said Yaghi, who holds UCLA’s Irving and Jean Stone Chair in Physical Sciences and is director of the CNSI’s Center for Reticular Chemistry. “I am optimistic that is within our reach. Potentially, we could create a material that can convert carbon dioxide into a fuel, or a material that can separate carbon dioxide with greater efficiency.”
Cells rely on a range of signalling systems to communicate with each other and to control their own internal workings. Scientists from the European Molecular Biology Laboratory (EMBL) in Hamburg, Germany, have now found a way to hack into a vital communications system, raising the possibility of developing new drugs to tackle disorders like neurodegeneration, cancer and cardiovascular disease. In a study published today in Science Signaling, they have pieced together the first snapshot of what two of the system’s components look like while interacting.
Rest at EMBL
It would certainly be interesting to have the time to follow the Myriad Genetics case (Association For Molecular Pathology et al v. United States Patent and Trademark Office et al). If you do have the time or just need to find a document, here is a link to the documents filed in the case so far (246 and counting).
