| Orangutans harbor ancient primate Alu Posted: 29 Apr 2012 08:46 PM PDT Alu elements infiltrated the ancestral primate genome about 65 million years ago. Once gained an Alu element is rarely lost so comparison of Alu between species can be used to map primate evolution and diversity. New research has found a single Alu, which appears to be an ancestral great ape Alu, that has uniquely multiplied within the orangutan genome. |
| Bioluminescent technology for easy tracking of GMO Posted: 29 Apr 2012 08:46 PM PDT It is important to be able to monitor genetically modified (GM) crops, not only in the field but also during the food processing chain. New research shows that products from genetically modified crops can be identified at low concentration, using bioluminescent real time reporter (BART) technology and loop mediated isothermal amplification (LAMP). The combination of these techniques was able to recognize 0.1% GM contamination of maize, far below the current EU limit of 0.9%. |
| Posted: 29 Apr 2012 12:22 PM PDT Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish. |
