| Scientists develop tools to make more complex biological machines from yeast Posted: 19 Mar 2012 04:43 PM PDT Scientists are one step closer to making more complex microscopic biological machines, following improvements in the way that they can "re-wire" DNA in yeast, according to new research.  |
| Posted: 19 Mar 2012 01:38 PM PDT A researcher has come up with a concept that may solve many of the problems that grounded the Concorde. An assistant professor of aeronautics and astronautics, says the solution, in principle, is simple: Instead of flying with one wing to a side, why not two?  |
| Genetic variation in human gut viruses could be raw material for inner evolution Posted: 19 Mar 2012 10:42 AM PDT A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. A new study sequenced the DNA of viruses -- the virome -- present in the gut of healthy people.  |
| The Viking journey of mice and men Posted: 19 Mar 2012 06:48 AM PDT House mice happily live wherever there are humans. When populations of humans migrate the mice often travel with them. New research has used evolutionary techniques on modern day and ancestral mouse mitochondrial DNA to show that the timeline of mouse colonization matches that of Viking invasion. During the Viking age (late 8th to mid 10th century) Vikings from Norway established colonies across Scotland, the Scottish islands, Ireland, and Isle of Man. They also explored the north Atlantic, settling in the Faroe Islands, Iceland, Newfoundland and Greenland. While they intentionally took with them domestic animals such as horses, sheep, goats and chickens they also inadvertently carried pest species, including mice.  |
