According to a paper published in Science, models of how animal and plant distributions are affected by climate change may also explain aspects of human evolution. The approach takes existing knowledge of the geographical spread of other species through the warming and cooling of the ice ages to provide a model that can be applied to human origins.

Tim Berners-Lee, the man attributed to the creation of the internet, gave a speech at an MIT symposium and shared his two decades worth of internet knowledge with the crowd. He spoke about a wide variety of issues, from net neutrality, which he is supportive of, to mobile web access. Berners-Lee's words concerning web access raised a couple of eyebrows, and definitely raised the interest of this writer. "Access to the Web is now a human right" he continues, "It's possible to live without the Web. It's not possible to live without water. But if you've got water, then the difference between somebody who is connected to the Web and is part of the information society, and someone who (is not) is growing bigger and bigger."

IN JUST a few thousand years, we humans have created a remarkable civilisation: cities, transport networks, governments, vast economies full of specialised labour and a host of cultural trappings. It all just about works, but it's hardly a model of rational design - instead, people in each generation have done the best they could with what they inherited from their predecessors. As a result, we've ended up trapped in what, in retrospect, look like mistakes. What sensible engineer, for example, would build a sprawling, low-density megalopolis like Los Angeles on purpose? Suppose we could try again. Imagine that Civilisation 1.0 evaporated tomorrow, leaving us with unlimited manpower, a willing populace and - most important - all the knowledge we've accumulated about what works, what doesn't, and how we might avoid the errors we got locked into last time. If you had the chance to build Civilisation 2.0 from scratch, what would you do differently?

Original theories were that, while sleeping, our minds were essential empty slates with little neurological activity. However, this recent study provides evidence that during sleep, our body replays the cognitive and motor skills learned throughout the preceding day. Providing evidence of this 'replay' hypothesis was the goal of this study.

Flat out wrong. That's what a team of Duke researchers has discovered, much to its surprise, about a long-accepted explanation of how nuclei collide to produce charged particles for electricity - a process receiving intense interest lately from scientists, entrepreneurs and policy makers in the wake of Japan's nuclear crisis.

In a paper published in Proceedings of National Academy of Sciences, Veronica Kwok, Li-Hai Tan, and their colleagues at the University of Hong Kong, conclude that the adult human brain is capable of new rapid growth when exposed to stimuli similar to what babies experience as they are learning from their environment.
