Neurocience & Freakonomics
Is neuroscience the new ‘Freakonomics’?April 9, 2012 The new generation of business thinking culls insights from the cutting edge of neuroscience, says The Washington Post Innovations blog. We are, as a society, experiencing a profound reappraisal of traditional economics and its shortcomings. The world is suddenly a lot more irrational than we ever thought, full of black swans. This new thinking about the way the human brain works is starting to impact everything — how supermarkets stock their shelves, when coupon offers are sent out to consumers, and how to devise the perfect title ... mais »
Computing Trend
The computing trend that will change everythingApril 10, 2012 The electrical efficiency of computing (the number of computations that can be completed per kilowatt-hour of electricity used) has doubled every year and a half since the dawn of the computer age. The power needed to perform a task requiring a fixed number of computations will continue to fall by half every 1.5 years (or a factor of 100 every decade). As a result, even smaller and less power-intensive computing devices will proliferate, paving the way for new mobile computing and communications applications that vastly in... mais »

Whole-genome sequences of supercentenarians reveal longevity cluesApril 11, 2012 *[+]*[image: genome_supercentenarians] Summary of patients’ characteristics (credit: Paola Sebastiani et al./Front. Gene.) A team of researchers has analyzed the complete genomic sequences of male and female supercentenarians, both over 114 years old. Surprisingly, the researchers showed that the DNA sequences are largely comparable to existing non-supercentenarian genomes, and the two individuals do not appear to carry most of the well-established human longevity-enabling variants already reported in th... mais »
Scientists and bankers
Scientists and bankers — a new model army Bankers must now surrender more information on their activities. Scientists should use it to build better system-wide financial models, says John Liechty. 11 April 2012 Article tools - - The financial system is in a credit-confidence trap. Like a badly balanced ship trying not to capsize during a storm, banks and financiers are unwilling to make loans or accept collateral in exchange for securing debts — they fear being overwhelmed by the next wave of crisis. Even though the first sovereign default, in Greece, has passed, ther... mais »

Autism Dx.
Can Autism Really Be Diagnosed in Minutes? A Harvard researcher says he's achieved exceptional accuracy in identifying autism by using just seven online questions and an evaluation of a short home video of the child, instead of conventional, face-to-face exams that can take hours. [image: Ferran Traite Soler / Vetta / Getty Images] Autism is an extremely complex diagnosis. Parental insight, physician observations and hours of data can factor into determining whether a child actually has the condition or is just a little on the quirky side.By Bonnie Rochman | @brochman | April 11, 2... mais »
ZIP & GENETIC Codes
Zip Code as Important as Genetic Code in Childhood Obesity ScienceDaily (Apr. 10, 2012) — Nearly 18 percent of U.S. school-aged children and adolescents are obese, as the rate of childhood obesity has more than tripled in the past 30 years. The prevalence of obesity puts children at greater risk of developing heart disease, type 2 diabetes, stroke and other illnesses, and of suffering severe obesity as adults. New study results indicate that where a child lives, including factors such as the neighborhood's walkability, proximity to higher quality parks, and access to healthy food, h... mais »

Reinventando o Sanitário

Invented at the turn of the 19th century, the flush version has vastly improved human life. The toilet has been credited with adding a decade to our longevity. The sanitation system to which it is attached was voted the greatest medical advance in 150 years by readers of the British Medical Journal. Unfortunately it is an impractical luxury for about two- thirds of the ... mais »

unnecessary left ventriculographies
Many left ventriculographies are unnecessaryAPRIL 5, 2012 Reed Miller * Stanford, CA* - Left ventriculography is performed in most coronary angiography cases, even when the same information has already been obtained noninvasively, a study of Aetna health benefit claims shows [1]. *Dr Ronald Witteles *(Stanford University, CA) and colleagues retrospectively analyzed claims data from 96 235 patients who underwent angiography in 2007. They found that left ventriculography was performed in 81.8% of cases and that, in 88% of those cases, the test was probably unnecessary because the patie... mais »
