A new route for pigs and people across the Pacific

The standard story of Pacific colonization is that people and their crops and livestock spread across it in a generally southwestern direction. Scientists from Durham University and the University of Oxford are renavigating the details. They looked at DNA from various pigs across the Pacific, and conclude that their journey may have started in what is now Vietnam. It has always been assumed that the people and their agriculture traveled together as a single package. This research indicates that different parts of the package took different routes.

There’s more detail at a Durham web site about pig domestication, but the actual paper does not seem to be available online yet. Here’s the press release announcing it.

Accessing biodiversity in Brazil

Brazil has new procedures in place (called Sisbio) to issue licences to collect biodiversity for teaching and research, according to an article on SciDevNet. They are supposed to make the whole access system much easier to navigate. And faster: what used to take up to two years should now take 45 days at most. This bit struck me in particular:

Scientists will eventually be able to use Sisbio to access satellite images of potential research areas and gauge research activity in areas so they can better plan their research.
