| The future of plant science: A technology perspective Posted: 02 Mar 2012 05:18 PM PST Plant science is key to addressing the major challenges facing humanity in the 21st Century, according to experts. Researchers argue that the development of new technology is key to transforming plant biology in order to meet human needs.  |
| Effects of environmental toxicants reach down through generations Posted: 02 Mar 2012 07:18 AM PST Scientists have now demonstrated that a variety of environmental toxicants can have negative effects on not just an exposed animal but the next three generations of its offspring. The animal's DNA sequence remains unchanged, but the compounds change the way genes turn on and off -- the epigenetic effect, according to molecular biologists. The researchers saw females reaching puberty earlier, increased rates in the decay and death of sperm cells and lower numbers of ovarian follicles that later become eggs.  |
| Protecting living fossil trees Posted: 02 Mar 2012 07:17 AM PST Scientists are working to protect living fossil trees in Fiji from the impact of climate change with cutting-edge DNA sequencing technology.  |
| Nearby chimpanzee populations show much greater genetic diversity than distant human populations Posted: 02 Mar 2012 07:17 AM PST Chimpanzee populations living in relatively close proximity are substantially more different genetically than humans living on different continents, according to a new study. The study suggests that genomics can provide a valuable new tool for use in chimpanzee conservation, with the potential to identify the population of origin of an individual chimpanzee or the provenance of a sample of bush meat.  |
| Artificial 'womb' unlocks secrets of early embryo development Posted: 02 Mar 2012 07:15 AM PST Pioneering work has helped reveal for the first time a vital process in the development of the early mammalian embryo.  |
| Breaking up isn't hard to do: The secret lives of corals on dark and stormy nights Posted: 01 Mar 2012 11:34 AM PST Forming a unique part of the animal kingdom, corals have built the only living entity visible from space: the Great Barrier Reef. Scientists have recently discovered a previously unknown reproductive strategy in corals, adding another dimension to our understanding of their complex life cycles.  |
| New possibilities for immune suppression through cyclic plant peptides Posted: 01 Mar 2012 05:39 AM PST Scientists have decoded a mechanism in cyclic plant peptides, known as cyclotides, from the family of coffee plants (Rubiaceae) that could open up new possibilities for immune suppression.  |
