Scientists have long held that fluid intelligence—reflected not by what you know but rather how well you solve novel problems—is largely inherited and relatively impervious to improvement. A raft of recent investigations, though, shows that some types of brain training—specifically those that exercise working memory and other so-called executive functions—can raise an individual's fluid intelligence.
Working memory training appears to boost fluid intelligence in children and adults alike. As training progresses, the brain regions taxed by working memory become less active when called on and more active at rest.

BEN Goldacre, doctor, columnist and author of the acclaimed bestseller Bad Science - in which he exposed and rubbished the "evidence" behind misleading and dubious claims from journalists, alternative therapists and government reports - is back with a controversial new book, Bad Pharma: How Drug Companies Mislead Doctors and Harm Patients (Fourth Estate).
Once more, he claims, science has been distorted by the corporations; drug manufacturers run bad trials on their products, which extort and deliberately exaggerate their benefits. When the test results are unflattering, the data is simply buried. Government regulators, too, are at fault, as are doctors and patient groups who are bribed by the $600-billion global pharmaceutical industry.
Early reports on the book suggest that Goldacre has uncovered "a fascinating, terrifying mess".
Scientists and academics are to be given extra protection from bullying corporations that use Britain's libel laws to suppress legitimate criticism and debate, the Government has indicated.
Ministers are to look at amending the Defamation Bill, which is currently being debated in the House of Lords, after strident criticism that their plans do not go far enough.
Scientists have warned that under current proposals there nothing to stop companies and the rich and powerful “silencing criticism” even if it is in the public interest.
They point to a string of recent cases where experts have been threatened with hugely expensive legal actions for raising legitimate concerns about medical products and allegedly unscrupulous practices by companies.
"If you want to be good in Science, you have to start asking good questions. You cannot ask good questions if you don't have good training. You have to be open to other fields. You have to feel it. Team up with others and remain very motivated to work hard. You have to love and live your Science." - Prof Jules A Hoffmann ( The Nobel Prize winner for discoveries on 'activation of innate immunity'. )
The United States faced down authoritarian governments on the left and right. Now it may be facing an even greater challenge from within
A large number of major party contenders for political office this year took antiscience positions against evolution, human-induced climate change, vaccines, stem cell research, and more. Such positions are surprising because the economy is such a big factor in this election, and half the economic growth since World War II can be traced to innovations in science and technology.
Partisans at both ends of the political spectrum have been guilty of science denialism. But the Republican version is particularly dangerous because it attacks the validity of science itself.
U.S. voters must push candidates and elected officials to express their views on the major science questions facing the nation or risk losing out to those countries with reality-based policies.
Do you think that a scientific focus on art runs the risk of reducing its emotional impact and stripping it of some of its necessary enigma? If not, why?
Only if you get into the details of the research itself. Science is cold only in the laboratory, but the ideas that come out of a laboratory are more enthralling than anything I've come across. Think of the fact of evolution, the fact that all of life evolved from single-celled organisms around three billion years ago. Scientists, after much work, discovered this, but why shouldn't poets and artists celebrate these eye-opening truths, the same way they have celebrated religious myths for countless centuries? The image of science as something mechanical needs to be done away with.

Despite hundreds of years of old wives' tales and, more recently, serious research, even the most devastating earthquakes are pretty much as unpredictable in 2012 as they were in prehistoric times.
The Italian earthquake trial, in which six seismologists and a civil servant were found guilty of manslaughter, has an eerie resonance with the Galileo trial of 1633.
The question is: was this trial about science or communication? While the media are filled with stories about science being on trial, claiming that the scientists have been convicted of failing to predict the earthquake, New Scientist points out that the conviction was actually for errors in communication.
It may sound like something straight out of a horror movie, but many animals can come under the zombie-like control of parasites. So what about humans?

Among those who make a living communicating science to the public, there are two main groups. There are those who began as writers, journalists, film makers, what have you, and somewhere along the way discovered a particular affinity for the subject of science. Increasingly, though, there’s a second group who received formal training in science, may even have made a career as a scientist, but somewhere along the way discovered that research wasn’t quite the right fit and instead turned to telling the stories of science.
A listener to Radio 4's PM programme got in touch recently asking why it did not get more scientists involved directly in its output.
So, for a each day this week, the programme has spoken to one scientist about the work they are doing, to try to learn more about what impact their work might have, and why a scientist chooses their particular field of inquiry.
The idea was to break out of the topical habit of only ever inviting scientists on to explain a particular story just because it is in the news, and learn about what scientists are up to when they are not being talking heads on a particular programme.
What they do: As scientists, we understand career development is difficult. That’s why RateMyPI.com was developed with the research professional and aspiring professionals in mind. You don’t start an experiment without a thorough knowledge base; why should choosing a principal investigator, collaborator, or employee be any different? It’s your career…take control of it!
In 1969, Princeton physicist Gerard O'Neill began looking outward to space colonies as the new frontier for humanity's expansion. A decade later, Eric Drexler, an MIT-trained engineer, turned his attention to the molecular world as the place where society's future needs could be met using self-replicating nanoscale machines. These modern utopians predicted that their technologies could transform society as humans mastered the ability to create new worlds, undertook atomic-scale engineering, and, if truly successful, overcame their own biological limits. The Visioneers tells the story of how these scientists and the communities they fostered imagined, designed, and popularized speculative technologies such as space colonies and nanotechnologies.
Patrick McCray traces how these visioneers blended countercultural ideals with hard science, entrepreneurship, libertarianism, and unbridled optimism about the future. He shows how they built networks that communicated their ideas to writers, politicians, and corporate leaders. But the visioneers were not immune to failure--or to the lures of profit, celebrity, and hype. O'Neill and Drexler faced difficulty funding their work and overcoming colleagues' skepticism, and saw their ideas co-opted and transformed by Timothy Leary, the scriptwriters of Star Trek, and many others. Ultimately, both men struggled to overcome stigma and ostracism as they tried to unshackle their visioneering from pejorative labels like "fringe" and "pseudoscience."
The Visioneers provides a balanced look at the successes and pitfalls they encountered. The book exposes the dangers of promotion--oversimplification, misuse, and misunderstanding--that can plague exploratory science. But above all, it highlights the importance of radical new ideas that inspire us to support cutting-edge research into tomorrow's technologies.
27 Science Fictions That Became Science Facts In 2012
We may never have our flying cars, but the future is here. From creating fully functioning artificial leaves to hacking the human brain, science made a lot of breakthroughs this year.
Cubic boron nitride, a material that in many ways resembles diamond. Boron nitride can be compressed into a superhard, transparent form—but unlike diamond and many other materials known for their extreme hardness, it is based not on carbon but on a latticework of boron and nitrogen atoms. Computer simulations have indicated that a rare crystalline form of boron nitride would resist indentation even better than diamond if it could be synthesized into large samples, and laboratory experiments have shown that more attainable forms of the stuff already approach the hardness of diamond.
Now a new set of experiments on a nanostructured form of boron nitride have yielded even greater measures of hardness than before. The new material exceeds that of some forms of diamond, according to the authors of a study reporting the findings in the January 17 issue of Nature.
The samples had a measured hardness of up to 108 gigapascals—slightly harder than synthetic diamond but less hard than polycrystalline diamonds made of nanoscale grains.

Cubic boron nitride, a material that in many ways resembles diamond. Boron nitride can be compressed into a superhard, transparent form—but unlike diamond and many other materials known for their extreme hardness, it is based not on carbon but on a latticework of boron and nitrogen atoms. Computer simulations have indicated that a rare crystalline form of boron nitride would resist indentation even better than diamond if it could be synthesized into large samples, and laboratory experiments have shown that more attainable forms of the stuff already approach the hardness of diamond.
Now a new set of experiments on a nanostructured form of boron nitride have yielded even greater measures of hardness than before. The new material exceeds that of some forms of diamond, according to the authors of a study reporting the findings in the January 17 issue of Nature.
The samples had a measured hardness of up to 108 gigapascals—slightly harder than synthetic diamond but less hard than polycrystalline diamonds made of nanoscale grains.
