A small, digital book startup thinks it has a solution to the age-old student lament: overpriced textbooks that have little value when the course is over. The answer? Make them open source -- and give them away.

So, when it comes to terrorism, it only works because of technology, because a small number of people, almost always men, can use technology for leverage. Nineteen terrorists armed with sticks and stones could do very little to affect the United States of America. But 19 terrorists armed with jet fuel-laden aircraft ...

We would have never known they existed if they hadn't leveraged technology.

A new model of evolution's origins traces the possible outlines of a critical and mysterious stage in Earth's infancy, when a few odd chemicals developed into the molecular ancestors of life as we know it.

In a study published today in the Proceedings of the National Academy of Sciences, linguists observed an artificial language evolve from random to ordered, naturally adapting in ways that assured its reproduction.

The Environmental Appeals Board blocked the EPA from issuing a permit to a proposed coal plant addition near Vernal, Utah, about 150 miles east of Salt Lake City. Perhaps more importantly, the quasi-independent board, composed of four highly regarded, experienced judges, ruled that the EPA needs to develop a single nationwide standard for dealing with carbon dioxide.

Entitled "Severe Space Weather Events - Understanding Societal and Economic Impacts," it describes the consequences of solar flares unleashing waves of energy that could disrupt Earth's magnetic field, overwhelming high-voltage transformers with vast electrical currents and short-circuiting energy grids. Such a catastrophe would cost the United States "$1 trillion to $2 trillion in the first year," concluded the panel, and "full recovery could take four to 10 years." That would, of course, be just a fraction of global damages.

people don't necessarily want to solve puzzles on their own. They often enjoy attacking them in online collaborative groups that include dozens, sometimes millions, of fans. These groups are collectively far smarter than their individual members, and regular puzzles don't stand a chance against that many brains.

School and learning as playground for sensemaking. Being on the cusp of the cusp of the question is where it's at: in this case the kids are putting together their own school as their first question.
