Noise and Signal - Nassim Taleb | Farnam Street - 0 views

  •  
    "There is a biological story with information. I have been repeating that in a natural environment, a stressor is information. So too much information would be too much stress, exceeding the threshold of antifragility. In medicine, we are discovering the healing powers of fasting, as the avoidance of too much hormonal rushes that come with the ingestion of food. Hormones convey information to the different parts of our system and too much of it confuses our biology. Here again, as with the story of the news received at too high a frequency, too much information becomes harmful. And in Chapter x (on ethics) I will show how too much data (particularly when sterile) causes statistics to be completely meaningless. Now let's add the psychological to this: we are not made to understand the point, so we overreact emotionally to noise. The best solution is to only look at very large changes in data or conditions, never small ones"

Our Social Nature: The Surprising Science of Smiles | Wired Science | Wired.com - 0 views

  •  
    All hail the powerful smile. The right smile, at the right time, wins friends and calms enemies. The smile held for too long, not long enough, flashed too intensively or too dimly, arouses suspicion, fear or anger. Far from being a straightforward show of joy, the language of smiles is filled with subtlety: a meld of our inner state, surroundings, social training, conscious and unconscious.

Parenting Style Plays Key Role In Teen Drinking : NPR - 0 views

  •  
    For teenagers, friends play a big role in the decision to take that first drink. And by the 12th grade, more than 65 percent of teens have at least experimented with alcohol. But what parents do during the high school years can also influence whether teens go on to binge drink or abuse alcohol. Researchers at Brigham Young University have found that teenagers who grow up with parents who are either too strict or too indulgent tend to binge drink more than their peers.
  •  
    For some adults, there is a tendency to go beyond the call of duty. Particularly, when they are faced with choosing to allow or not allow. Maybe the scientific explanation is to do or not to do. And the reaction isn't always the most appropriate but it is better to be safe than sorry. What is the scientific explanation for adults that don't react or react inappropriately even when it's involves saving a teenager? What is the scientific solution for those in the center of difficult situations, who are not strict or liberal? What does a mind do when it is present many times in a teenage situation and it is not the parent?

More breaks from sitting are good for waistlines and hearts - 0 views

  •  
    ScienceDaily (Jan. 13, 2011) - It is becoming well accepted that, as well as too little exercise, too much sitting is bad for people's health. Now a new study has found that it is not just the length of time people spend sitting down that can make a difference, but also the number of breaks that they take while sitting at their desk or on their sofa. Plenty of breaks, even if they are as little as one minute, seem to be good for people's hearts and their waistlines.

Michael Lewis: Obama's Way | Vanity Fair, AUTOPILOT - 0 views

  •  
    ""You'll see I wear only gray or blue suits," he said. "I'm trying to pare down decisions. I don't want to make decisions about what I'm eating or wearing. Because I have too many other decisions to make." He mentioned research that shows the simple act of making decisions degrades one's ability to make further decisions. It's why shopping is so exhausting. "You need to focus your decision-making energy. You need to routinize yourself. You can't be going through the day distracted by trivia." The self-discipline he believes is required to do the job well comes at a high price. "You can't wander around," he said. "It's much harder to be surprised. You don't have those moments of serendipity."

Maurice Levi: Winterkind Summer babies less likely to be CEOs - 0 views

  •  
    "Levi and his co-authors, former Sauder PhD students Qianqian Du and Huasheng Gao, investigated the birth-date effect in a sample of 375 CEOs from S&P 500 companies between 1992 and 2009. "Our study adds to the growing evidence that the way our education system groups students by age impacts their lifelong success," says Prof. Levi. "We could be excluding some of the business world's best talent simply by enrolling them in school too early.""

    "Currently making 1.67TB of research data available. Sharing data is hard. Emails have size limits, and setting up servers is too much work. We've designed a distributed system for sharing enormous datasets - for researchers, by researchers. The result is a scalable, secure, and fault-tolerant repository for data, with blazing fast download speeds."

Chris Mooney | The Science of Debiasing: The New "Debunking Handbook" Is a Treasure Tro... - 0 views

  •  
    "I simply cannot believe that John Cook of Skeptical Science and psychologist Stephan Lewandowsky managed, in just 8 pages, to create something as magnificent as their new Debunking Handbook. It is packed not only with wonderful graphics, but also with a clear explanation of why many attempts to defeat misinformation fail, and what steps must be taken to do a better job. The core issue, of course, is one that I've written much about-too many scientists assume that that facts win out on their own, but that isn't actually true"

Over-Regulation of Parthenotes Stifles Valuable Scientific Research - 0 views

  •  
    A recent article in Scientific American questioned whether research on stem cell lines derived from unfertilized eggs was too tightly regulated by the federal government. Now that technology allows the creation of stem cells without fertilization, there is no question that federal laws and guidelines are overly restrictive, causing a detrimental effect on valuable scientific inquiry.

    ""It seems to me that our three basic needs, for food and security and love, are so mixed and mingled and entwined that we cannot straightly think of one without the others." - M.F.K. Fisher Human beings are notoriously terrible at knowing when we're no longer hungry. Instead of listening to our stomach - a very stretchy container - we rely on all sorts of external cues, from the circumference of the dinner plate to the dining habits of those around us. If the serving size is twice as large (and American serving sizes have grown 40 percent in the last 25 years), we'll still polish it off. And then we'll go have dessert."

    "Suffering for Fashion … and Sex Appeal? Nine out of ten women wear shoes that are too tight for them. And eight out of ten women admit to wearing shoes that hurt... These ideas have been explored previously by numerous other researchers. For example, Rossi notes that high-heels alter the tilt of the pelvis, resulting in more prominence of the buttocks and displaying of the breasts, creating a "come-hither pose" also described by Rossi as the "pouter pigeon" pose, "with lots of breast and tail balanced precariously on a pair of stilts " http://ed.iiQii.de/gallery/Querdenkerinnen/High_Heel_Pumps_wikipedia_org

Joel Pearson: Taking a break is secret to success, #infooverload, cognitive load - 0 views

    "At least it doesn't when you practise over and over again without a break. Sydney scientists have found learning improves when students take a rest from continuous study or training. ''It seems intuitive that every minute of study should make you better, but, actually, if you do too much it might backfire and you end up wasting time,'' said the study's lead researcher, Joel Pearson."

Dark Energy: Still a Puzzle | Cosmic Variance | Discover Magazine - 0 views

  •  
    People should not be afraid of dark energy. Remember that the problem with the cosmological constant isn't that it's mysterious and ill-motivated - it's that it's too small! The naive theoretical prediction is larger than what's required by observation by a factor of 10^120. That's a puzzle, no doubt, but setting it equal to zero doesn't make the puzzle go away - then it's smaller than the theoretical prediction by a factor of infinity.

Use of DNA evidence is not an open and shut case, professor says - 0 views

  • In his new book, "The Double Helix and the Law of Evidence" (Harvard University Press), Kaye focuses on the intersection of science and law, and emphasizes that DNA evidence is merely information. "There's a popular perception that with DNA, you get results," Kaye said. "You're either guilty or innocent, and the DNA speaks the truth. That goes too far. DNA is a tool. Perhaps in many cases it's open and shut, in other cases it's not. There's ambiguity."
  • One of the book's key themes is that using science in court is hard to do right. "It requires lawyers and judges to understand a lot about the science," Kaye noted. "They don't have to be scientists or technicians, but they do have to know enough to understand what's going on and whether the statements that experts are making are well-founded. The lawyers need to be able to translate that information into a form that a judge or a jury can understand." Kaye also believes that lawyers need to better understand statistics and probability, an area that has traditionally been neglected in law school curricula. His book attempts to close this gap in understanding with several sections on genetic science and probability. The book also contends that scientists, too, have contributed to the false sense of certainty, when they are so often led by either side of one particular case to take an extreme position. Scientists need to approach their role as experts less as partisans and more as defenders of truth. Aiming to be a definitive history of the use of DNA evidence, "The Double Helix and the Law of Evidence" chronicles precedent-setting criminal trials, battles among factions of the scientific community and a multitude of issues with the use of probability and statistics related to DNA. From the Simpson trial to the search for the last Russian Tsar, Kaye tells the story of how DNA science has impacted society. He delves into the history of the application of DNA science and probability within the legal system and depicts its advances and setbacks.
  •  
    Whether used to clinch a guilty verdict or predict the end of a "CSI" episode, DNA evidence has given millions of people a sense of certainty -- but the outcomes of using DNA evidence have often been far from certain, according to David Kaye, Distinguished Professor of Law at Penn State.
