Interactive map of human genetic history revealed A global map detailing the genetic histories of 95 different populations across the world, showing likely genetic impacts of European colonialism, the Arab slave trade, the Mongol Empire and European traders near the Silk Road mixing with people in China, has been revealed for the first time. The interactive map, produced by researchers from Oxford University and UCL, details the histories of genetic mixing between each of the 95 populations across Europe, Africa, Asia and South America spanning the last four millennia. The study, published this week in Science, simultaneously identifies, dates and characterises genetic mixing between populations. To do this, the researchers developed sophisticated statistical methods to analyse the DNA of 1490 individuals in 95 populations around the world. "Because our approach uses only genetic data, it provides information independent from other sources.

40 more maps that explain the world Maps seemed to be everywhere in 2013, a trend I like to think we encouraged along with August's 40 maps that explain the world. Maps can be a remarkably powerful tool for understanding the world and how it works, but they show only what you ask them to. You might consider this, then, a collection of maps meant to inspire your inner map nerd. I've searched far and wide for maps that can reveal and surprise and inform in ways that the daily headlines might not, with a careful eye for sourcing and detail. I've included a link for more information on just about every one. Enjoy. 1. Data source: Oak Ridge National Laboratory, World Bank.

EarthPulse, Maps, Global Trends, Human Impact Globalization, the international exchange of goods, services, cultures, ideas, has brought increased wealth for many and transformed forever the way humans interact. But while its roots may be in commerce, globalization's effects can be very personal. Advances in communication and transportation have created a rich, unprecedented mixing of cultures throughout the world. But there is a drawback. As international travel, economic migration, and the global spread of music, films, and literature bring more people than ever into intimate contact, human diversity is vanishing. A shared language is perhaps the most profound expression of group identity and a critical tool for passing cultural knowledge from one generation to the next. Workers, from wealthy consultants to unskilled laborers, are also on the move as never before.

If you're like me, the concept of synthetic biology—the application of engineering techniques to the building blocks of life—is pretty hard to get your head around. I get synthesizing, say, material to make clothes out of. But synthesizing new life forms? Apparently, while I stand slack-jawed, the novel technology is quickly going mainstream. Hoping to give new meaning to the term "natural light," a small group of biotechnology hobbyists and entrepreneurs has started a project to develop plants that glow, potentially leading the way for trees that can replace electric street lamps and potted flowers luminous enough to read by. What could be more innocuous than plants that generate useful light? And they're not financing the project by tapping Wall Street or big banks, but rather the democratic cash-raising method of our age par excellence, the Kickstarter campaign. What could possibly go wrong? But regulating novel technologies has proven difficult here in the United States.
