    Nature Video: Untangling the brain

    Two teams of neuroscientists have reconstructed the wiring of tiny pieces of the brain and related it to the function of individual cells. To understand how the brain works, you need to know what connects to what. But it has so many cells, making so many connections, that this is a big challenge.

    Better cell phone battery life? Recapture wasted LCD backlighting

    UCLA researchers have developed LCDs with photovoltaic polarizers that can turn light wasted by the screen back into energy for the phone. Since screens use the most battery power, the technique could lead to significant increases in battery life.

    How the net traps us all in our own little bubbles

    An invisible revolution has taken place is the way we use the net, but the increasing personalisation of data by search engines such as Google threatens to limit our access to information and enclose us in a self-reinforcing world view, writes Eli Pariser in an extract from The Filter Bubble

    An explainer is not “everything you need to know about X.” But it is the starting point, the big picture. So while we hope that you enjoy the song, what we really want you to do is read more about hydraulic fractured drilling, so you can truly understand “what the frack is going on.”

    Practice Mapping - Visual reference

    The Practice Mapping project aims to expose the interaction dynamics involved in a practice. It is, however, not only interested in the static network of the entities involved in the practice, but also, and perhaps even more so, in the dynamics of this network: how it grows and transforms over time.
