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

What does the future of science look like? About a year ago, I was asked this question. My response then was: Transdisciplinary collaboration. Researchers from a variety of domains-biology, philosophy, psychology, neuroscience, economics, law-all coming together, using inputs from each specialized area to generate the best comprehensive solutions to society's more persistent problems. Indeed, it appears as if I was on the right track, as more and more academic research departments, as well as industries, are seeing the value in this type of partnership. Now let's take this a step further. Not only do I think we will be relying on inputs from researchers and experts from multiple domains to solve scientific problems, but I see society itself getting involved on a much more significant level as well. And I don't just mean science awareness. I'm talking about actually participating in the research itself. Essentially, I see a huge boom in the future for Citizen Science.

One the oddities about the current economic doldrums afflicting the developed world is that if you look at the global average, this is almost certainly the best time to be alive in human history. Not only have we seen rapid per capita GDP growth in many poor countries, but even in countries that haven't gotten richer major development progress has occurred. Last, but by no means least, the world is getting much less violent: In fact, the last decade has seen fewer war deaths than any decade in the past 100 years, based on data compiled by researchers Bethany Lacina and Nils Petter Gleditsch of the Peace Research Institute Oslo. Worldwide, deaths caused directly by war-related violence in the new century have averaged about 55,000 per year, just over half of what they were in the 1990s (100,000 a year), a third of what they were during the Cold War (180,000 a year from 1950 to 1989), and a hundredth of what they were in World War II. If you factor in the growing global population, which has nearly quadrupled in the last century, the decrease is even sharper. Far from being an age of killer anarchy, the 20 years since the Cold War ended have been an era of rapid progress toward peace. This is major good news.

Why More Equality? Our thirty years research shows that: 1) In rich countries, a smaller gap between rich and poor means a happier, healthier, and more successful population. Just look at the US, the UK, Portugal, and New Zealand in the top right of this graph, doing much worse than Japan, Sweden or Norway in the bottom left.

Much of what medical researchers conclude in their studies is misleading, exaggerated, or flat-out wrong. So why are doctors-to a striking extent-still drawing upon misinformation in their everyday practice? Dr. John Ioannidis has spent his career challenging his peers by exposing their bad science. 

Slovenian philosopher Slavoj Zizek, akaThe Elvis of cultural theory, is given the floor to show of his polemic style and whirlwind-like performance. The Giant of Ljubljana is bombarded with clips of popular media images and quotes by modern-day thinkers revolving around four major issues: the economical crisis, environment, Afghanistan and the end of democracy. Zizek grabs the opportunity to ruthlessly criticize modern capitalism and to give his view on our common future. We communists are back! is the closing remark of Slavoj Zižeks provocative performance. Our current capitalist system, that everyone believed would be smoothly spread around the globe, is untenable. We find ourselves on the brink of big problems that call for big solutions. Whatever is left of the left, has been hedged in by western liberal democracy and seems to lack the energy to come up with radical solutions. Not Zižek.

The scientific community has long agreed that our dependence on fossil fuels inflicts massive damage on the environment and our health, while warming the globe in the process. But beyond the damage these fuels cause to us now, what will happen when the world's supply of oil runs out?

December 9th, 02005 - Sam Harris"The View From The End Of The World"This is an audio only presentation. This talk took place in the Conference Center Golden Gate Room, San Francisco. Quote: With gentle demeanor and tight argument, Sam Harris carried an overflow audience into the core of one of the crucial issues of our time: What makes some religions lethal? How do they employ aggressive irrationality to justify threatening and controlling non-believers as well as believers? What should be our response? Harris began with Christianity. In the US, Christians use irrational arguments about a soul in the 150 cells of a 3-day old human embryo to block stem cell research that might alleviate the suffering of millions. In Africa, Catholic doctrine uses tortured logic to actively discourage the use of condoms in countries ravaged by AIDS. "This is genocidal stupidity," Harris said. Faith trumps rational argument. Common-sense ethical intuition is blinded by religious metaphysics. In the US, 22% of the population are CERTAIN that Jesus is coming back in the next 50 years, and another 22% think that it's likely. The good news of Christ's return, though, can only occur following desperately bad news. Mushroom clouds would be welcomed. "End time thinking," Harris said, "is fundamentally hostile to creating a sustainable future." Harris was particularly critical of religious moderates who give cover to the fundamentalists by not challenging them. The moderates say that all is justified because religion gives people meaning in their life. "But what would they say to a guy who believes there's a diamond the size of a refrigerator buried in his backyard? The guy digs out there every Sunday with his family, cherishing the meaningthe quest gives them." "I've read the books," Harris said. "God is not a moderate." The Bible gives strict instructions to kill various kinds of sinners, and their relatives, and on occasion their entire towns. Yet slavery is challenged nowhere in the New or

Peak Oil is the point at which petroleum production reaches its greatest rate just before going into perpetual decline. In "Peak Oil and a Changing Climate," a new video series from The Nation and On The Earth productions, radio host Thom Hartmann explains that the world will reach peak oil within the next year if it hasn't already. As a nation, the United States reached peak oil in 1974, after which it became a net oil importer. Bill McKibben, Noam Chomsky, Nicole Foss, Richard Heinberg and the other scientists, researchers and writers interviewed throughout "Peak Oil and a Changing Climate" describe the diminishing returns our world can expect as it deals with the consequences of peak oil even as it continues to pretend it doesn't exist. These experts predict substantially increased transportation costs, decreased industrial production, unemployment, hunger and social chaos as the supplies of the  fuels on which we rely dwindle and eventually disappear. Chomsky urges us to anticipate the official response to peak oil based on how corporations, news organizations and other institutions have responded to global warming: obfuscation, spin and denial. James Howard Kunstler says that we cannot survive peak oil unless we "come up with a consensus about reality that is consistent with the way things really are." This documentary series hopes to help build that consensus. Click here to watch the introductory video, and check back here for new videos each Wednesday.

"Those who make peaceful evolution impossible make violent revolution inevitable."- John F. KennedyThere's one thing for sure: 2008 isn't anything like politics as usual.The corporate media (with their unerring eye for the obvious point) is fixated on the narrative that, for the first time ever, Americans will likely end this year with either a woman or a black man headed for the White House. Bloggers are telling stories from the front lines of primaries and caucuses that look like something from the early 60s - people lining up before dawn to vote in Manoa, Hawaii yesterday; a thousand black college students in Prairie View, Texas marching 10 miles to cast their early votes in the face of a county that tried to disenfranchise them. In recent months, we've also been gobstopped by the sheer passion of the insurgent campaigns of both Barack Obama and Ron Paul, both of whom brought millions of new voters into the conversation - and with them, a sharp critique of the status quo and a new energy that's agitating toward deep structural change.There's something implacable, earnest, and righteously angry in the air. And it raises all kinds of questions for burned-out Boomers and jaded Gen Xers who've been ground down to the stump by the mostly losing battles of the past 30 years. Can it be - at long last - that Americans have, simply, had enough? Are we, finally, stepping out to take back our government - and with it, control of our own future? Is this simply a shifting political season - the kind we get every 20 to 30 years - or is there something deeper going on here? Do we dare to raise our hopes that this time, we're going to finally win a few? Just how ready is this country for big, serious, forward-looking change?Recently, I came across a pocket of sociological research that suggested a tantalizing answer to these questions - and also that America may be far more ready for far more change than anyone really believes is possible at this moment. In fac

Research suggests that psychedelics may be better than antidepressants, which tend to dampen or suppress psychological problems without necessarily curing them.

The NAACP has just passed a historic resolution demanding an end to the War on Drugs.  The resolution comes as young Black male unemployment hovers near 50 percent and the wealth gap's become a veritable gulf. So why is the forty-year-old "War on Drugs" public enemy number one for the nation's oldest civil rights organization? Well here's why:  it's not extraneous - it's central: the war on drugs is the engine of 21st century discrimination - an engine that has brought Jim Crow into the age of Barack Obama.     Author Michelle Alexander lays out the statistics -- and the stories --  of 21st Century Jim Crow in her ought-to-blow-your-socks off book: "The New Jim Crow: Mass Incarceration in an Age of Colorblindness." I had a chance to sit down with Alexander earlier this summer. We'll be posting the full interview in two parts.     "We have managed decades after the civil rights movement to create something like a caste system in the United States," says Alexander in part one here  "In major urban areas, the majority of African American men are either behind bars, under correctional control or saddled with criminal record and once branded as criminal or a felon, they're trapped for life in 2nd class status."     It's not just about people having a hard time getting ahead and climbing the ladder of success. It's about a rigged system. Sound familiar?  Like the Pew Research Center report on household wealth and the Great Recession -- the NAACP resolution story was a one-day news-blip - despite the fact that it pierces the by-your-bootstraps myth that is at the heart of - you pick it - the deficit, the stimulus, the tax code - every contemporary US economic debate.     White America just maybe ought to pay attention. With more and more Americans falling out of jobs and into debt, criminal records are a whole lot easier to come by than life-sustaining employment.  Contrary to the conventional media version, the "Drug War" story is not a people with problems

According to the American Society of Civil Engineers, repairing our crumbling infrastructure will require an investment of $2.2 trillion over five years. (Source: ASCE Report Card for America's Infrastructure) For every $100 billion spent on infrastructure projects such as rebuilding our roads and bridges, public transportation, energy transmission and water systems, 1.8 million jobs would be created. (Source: Heintz, Robert, James Pollin, and Heidi Garrett-Peltier, "How Infrastructure Investments Support the U.S. Economy: Employment, Productivity and Growth." Amherst, MA: Political Economy Research Institute, January 2009) The current Congress hasn't passed a single job-creation bill. Instead of creating jobs, they've been killing them and slowing down the economic recovery with severe budget cuts. In fact, 1.8 million jobs will be lost as a result of the recent debt ceiling deal to cut government spending while failing to extend the payroll tax and emergency unemployment benefits.

Here we go again. The government and corporate media are pumping out more propaganda on vital economic statistics to mask the severity of our economic crisis. Deceptive unemployment, GDP, inflation and poverty measures are easily exposed with some research and a closer look at the data. The latest deception comes from the Census Bureau in their annual poverty report, which is now uncritically being "reported" on throughout the corporate media and echoing throughout online news outlets as well. The new Census data reveals that a stunning 46.2 million Americans, 15.1% of the population, lived in poverty in 2010. This is an increase of 2.6 million people since 2009. While these are staggering statistics that represent the highest number of American people to ever live in poverty, and a dramatic year-over-year increase, it significantly undercounts the total. The Census Bureau poverty rate is a highly flawed measurement that uses outdated methodology. The Census measures poverty based on costs of living metrics established in 1955 - 56 years ago. They ignore many key factors, such as the increased costs of medical care, child care, education, transportation, and many other basic expenses. They also don't factor geographically-based costs of living. For example, try finding a place to live in New York that costs the same as a place in Florida. A much more accurate measurement of poverty, which factors in these vital cost of living variables, comes from the National Academy of Sciences (NAS). Unlike the Census poverty measure, which gets significant coverage throughout the corporate media, the NAS measurement gets little, if any, mainstream media coverage.

ScienceDaily (Apr. 15, 2011) - Drug-resistant strains of Staphylococcus aureus, a bacteria linked to a wide range of human diseases, are present in meat and poultry from U.S. grocery stores at unexpectedly high rates, according to a nationwide study by the Translational Genomics Research Institute (TGen).

Social Security didn't create the deficit, but America's seniors are being presented with a fake Social Security crisis to try to trick them into accepting reduced benefits. Social Security will be able to pay 100% of its benefits through 2037 without any changes whatsoever. So, why the panic today? If seniors accept cuts to Social Security benefits today, a surplus cash flow will build in the Social Security trust fund. According to the Congressional Research Service, "Social Security's cash surpluses are borrowed by the U.S. Treasury and can be used for tax cuts, spending or repaying debt." Social Security benefit cuts are increasing taxes paid to Social Security or extending retirement age will give more money for tax cuts spending or repaying the debt. Except for one thing: Social Security money belongs to those who have paid into the fund, it's not the government's money to use it; it shouldn't be the government's money to play with. Senior citizens should not have to accept a reduced standard of living to finance tax cuts for the rich. We must take a stand for senior citizens and protect Social Security and protect future generations from this raid on Social Security's funds.
