A decades-old mystery of why a naturally-occurring organic crystal fluoresces blue under ultra-violet light, yet when grown under laboratory conditions fluoresces with an intense green colour, has been solved by scientists …
Tim Werner, a senior scientist at the New England Aquarium’s Anderson Cabot Center for Ocean Life, told the AP: “If we can see how they get entangled, it would help us prevent it. The technology in computers has evolved to a state where we can model these things.”

More recent estimates suggest that if the pest spreads to Marlborough, production losses over the next eight years could amount to $383 million.

William Henry Perkin wasn’t trying to make Red #40 in his lab that day. As a research assistant for a famed chemist, he was trying to whip up synthetic quinine, a treatment for malaria. Perkin was interested in the properties of coal tar, an abundant byproduct of coke fuel, which comes from heating coal. But instead, he ended up with a dark powder. Washing out his flask with alcohol, Perkin was struck by the residue’s bright purple color. He tried using it to dye silk, and it was a success. Perkin had found the world’s first synthetic dye.

The crystals of HC8 were tiny and scattered only weakly as diffracting crystals. Despite ~60 hours of prolonged measurement, no observable data were observed beyond 1.05 Å. Having acceptable data up to 0.83 Å would have required a measurement of several weeks, and therefore, a data strategy up to 1.0 Å only was used. The crystal structure displayed acceptable atomic displacement ellipsoids, so the relatively low data resolution does not appear to have an influence on the structure quality. For the structure of S-HC8, the terminal imidazole ring of both independent molecules appeared to be disordered over two independent positions, which also implied that two different sets of water molecules were present in the channels. The relative occupancies of the positionally disordered phenyl rings were approximately 0.8/0.2 in both cases. A number of distance and vibration restraints were used to keep an acceptable geometry of the rings and reasonable atomic displacement parameters. Because the anomalous scattering was negligible for the used x-ray wavelength, the absolute configuration was set in such a way as to be in agreement with the MD simulations reported by Licsandru et al. (14), notably concerning the orientation of the water molecules in the channel. The crystals of R-HC8 were also tiny and weakly scattering even with synchrotron data, producing only a very low mean intensity, <I/σ(I)> = 5.4 for 23652 reflections.
Tourism New Zealand boss Stephen England-Hall says the booming tourism industry needs to be careful that visiting here doesn’t get too expensive.
However, it warned that any increased cost imposed on visitors to New Zealand will increase the expectations they have.
