By DTI MELBOURNE, Australia: Prebiotic compounds, whose origin can be traced back billions of years, have been studied intensively since their discovery several years ago. Now, a team of researchers in Australia has found that these prehistoric mole- cules can be used to modify surfaces of medical implants, reducing the riskofinfectionandrejection. Thenewcoatingmethodwasdevel- oped by the Commonwealth Scienti- fic and Industrial Research Organisa- tion(CSIRO)incollaborationwithmi- crobiologistsatMonashUniversity. Although surface modification methods span a wide variety of ap- plications,rangingfromsolarcellsto implantable medical devices, there areveryfewsimplegenericaqueous coating methods that are both ro- bust and versatile, as well as easily applicable over a range of substrate materials, the researchers reported intheirpaper.Therefore,theyexam- inedthesuitabilityoftheaminoma- lononitrile polymerisation process for the formation of coatings on a rangeofsubstratematerials.

By DTI NAPLES,Italy:Tothisday,researchers have not been able to scan and analyse the world-famous plaster casts of the people and animals of Pompeii who died in the volcanic eruptions of Mount Vesuvius in AD 79. Now, with the help of a 16-layer scanner, an interdisciplinary team was able to create digital 3-D re- constructions of the skeletons and dentalarchesofthevolcano’svictims forthefirsttime. Amongotherthings,thescientific tests,whichincludedtheuseofaspe- cialmulti-layer CTscanner,laserim- aging and DNA sampling, revealed thatthecity’sinhabitantshadnearly perfectteeth. “We discovered the absence of cavities in the teeth. This is very in- terestingandnotthatsurprising,be- cause we all know about the healthy Mediterranean diet and this has re- ally shown up in the early analyses,” said Massimo Osanna, superintend- entatthearchaeologicalsite.
