In the wake of paralyzing injury to a Rutgers student, and mounting evidence of permanent brain damage in many others, it's time for new approach to sports injuries: all-fault insurance.

During the past 15 years, the World Wide Web has created remarkable new methods for harnessing the creativity of people in groups, and in the process has created powerful business models that are reshaping our economy. As the Web has undermined old media and software companies, it has demonstrated the enormous power of a new approach, often referred to as Web 2.0. In a nutshell: the secret to the success of bellwethers like Google, Amazon, eBay, Craigslist, Wikipedia, Facebook, and Twitter is that each of these sites, in its own way, has learned to harness the power of its users to add value to-no, more than that, to co-create-its offerings.

ScienceDaily (Dec. 3, 2010) - Earth has run out of room to expand fisheries, according to a new study led by University of British Columbia researchers that charts the systematic expansion of industrialized fisheries.

From whatever angle you approach it, the present offers no way out. This is not the least of its virtues. From those who seek hope above all, it tears away every firm ground. Those who claim to have solutions are contradicted almost immediately. Everyone agrees that things can only get worse. "The future has no future" is the wisdom of an age that, for all its appearance of perfect normalcy, has reached the level of consciousness of the first punks. 

I've written before about the crisis of inequality in the United States and about the quasi-religious abhorrence of "wealth redistribution" that causes many Americans to oppose tax increases, even on the ultra rich. The conviction that taxation is intrinsically evil has achieved a sadomasochistic fervor in conservative circles-producing the Tea Party, their Republican zombies, and increasingly terrifying failures of governance. Happily, not all billionaires are content to hoard their money in silence. Earlier this week, Warren Buffett published an op-ed in the New York Times in which he criticized our current approach to raising revenue. As he has lamented many times before, he is taxed at a lower rate than his secretary is. Many conservatives pretend not to find this embarrassing. Conservatives view taxation as a species of theft-and to raise taxes, on anyone for any reason, is simply to steal more. Conservatives also believe that people become rich by creating value for others. Once rich, they cannot help but create more value by investing their wealth and spawning new jobs in the process. We should not punish our best and brightest for their success, and stealing their money is a form of punishment. Of course, this is just an economic cartoon. We don't have perfectly efficient markets, and many wealthy people don't create much in the way of value for others. In fact, as our recent financial crisis has shown, it is possible for a few people to become extraordinarily rich by wrecking the global economy. Nevertheless, the basic argument often holds: Many people have amassed fortunes because they (or their parent's, parent's, parents) created value. Steve Jobs resurrected Apple Computer and has since produced one gorgeous product after another. It isn't an accident that millions of us are happy to give him our money. But even in the ideal case, where obvious value has been created, how much wealth can one person be allowed to keep? A trillion doll

Educational researchers at the Technical University of Munich (TUM) have found that schoolchildren can independently develop strategies for solving complex mathematical tasks, with weaker students proving just as capable as their stronger classmates. Researchers in mathematics education worked with approximately 1600 8th grade high-school students in various German states. Following an introduction to the general topic by their teachers, the school children were given a workbook of geometric tasks that they had to solve on paper and using a computer over four school periods. Calculating the surface area of Gran Canaria was one of the real-world, free-form assignments the students had to tackle. The workbook material included explanations and examples of various problem-solving approaches. The teachers took a back seat during the session but were on hand to answer questions from the children, who worked in pairs. After testing the students' skills before and after the session, the researchers recorded a significant improvement in their capabilities. The students learned to apply mathematics more effectively, the researchers said. The students were also able to call on these skills in a further test three months later. "We expected students who were weaker at math to benefit more from a greater degree of guidance through the module," said professor Kristina Reiss.  "But we didn't see a significant difference between these and stronger students." The researchers also found that there were also no differences between boys and girls. "We now know that students - also those who are weaker in math - have the skills to master even very complex subject matters at their own pace," said Reiss. Topics: Cognitive Science/Neuroscience

AS Election Day approaches, serious discussion about economic policies is hamstrung by the devotion of both parties to reducing taxes. The big reason, of course, is that President Bush emphasizes tax cuts, including elimination of the estate tax, to the exclusion of almost everything else. The Democrats, in turn, hesitate to propose an economic plan that does not include long-term reductions for middle-income workers, and most refuse to talk about rescinding the Bush tax cuts for the wealthy. But the degree of misleading information emanating from both Washington and the media about how taxes affect the economy is disturbing. As I listen to the radio, watch TV news and read a variety of newspapers, it seems that quite a few Americans, including economics writers and media hosts, think that low-tax countries unquestionably grow faster than high-tax economies. Right and left, they seem to attribute more rapid growth in America to lower taxes. What may surprise them is that there is no evidence for that. ''You can make a theoretical case that high taxes impede economic growth, but it is just not supported by the evidence in the U.S. or across countries,'' said William Easterly, a former World Bank economist soon to join the faculty of New York University.
