    "Radar aims to automate local reporting with large public databases from government agencies or local law enforcement - basically roboticizing the work of reporters. Stories from the data will be penned using Natural Language Generation, which converts information gleaned from the data into words. The robotic reporters won't be working alone. The grant includes funds allocated to hire five journalists to identify datasets, as well as curate and edit the news articles generated from Radar. The project also aims to create automated ways to add images and video to robot-made stories."

  • in a discipline that regards ingenuity as the ultimate virtue, those who engage in the grunt work of data cleaning and replication receive few rewards. Nobel prizes are not awarded for constructing new historical estimates of GDP that allow policy analysis to be extended back in time.
  • How could a flawed study have appeared first in the prestigious working-paper series of the National Bureau of Economic Research (NBER) and then in a journal of the American Economic Association? And, if this was possible, why should policymakers and a discerning public vest any credibility in economic research?CommentsView/Create comment on this paragraphIt was possible because economists are not obliged to make their data and programs publicly available when publishing scientific research. It is said that NBER working papers are even more prestigious than publication in refereed journals. Yet the Bureau does not require scholars to post their data and programs to its Web site as a condition for working-paper publication.
  • Statistics are helpful. But in economics, as in other lines of social inquiry, they are no substitute for proper historical analysis.

    "Big data promises big progress. But large data sets also make replication impossible without the author's cooperation. And the incentive for authors to cooperate is, at best, mixed. It is therefore the responsibility of editorial boards and the directors of organizations like the NBER to make open access obligatory."

The Origins of "Basic Research" - 0 views

Science Basic Research Research Google Search

shared by Weiye Loh on 21 Oct 12 - No Cached
  • For many scientists, "basic research" means "fundamental" or "pure" research conducted without consideration of practical applications. At the same time, policy makers see "basic research" as that which leads to societal benefits including economic growth and jobs.
  • The mechanism that has allowed such divergent views to coexist is of course the so-called "linear model" of innovation, which holds that investments in "basic research" are but the first step in a sequence that progresses through applied research, development, and application. As recently explained in a major report of the US National Academy of Sciences: "[B]asic research ... has the potential to be transformational to maintain the flow of new ideas that fuel the economy, provide security, and enhance the quality of life" (Rising Above the Gathering Storm).
  • A closer look at the actual history of Google reveals how history becomes mythology. The 1994 NSF project that funded the scientific work underpinning the search engine that became Google (as we know it today) was conducted from the start with commercialization in mind: "The technology developed in this project will provide the 'glue' that will make this worldwide collection usable as a unified entity, in a scalable and economically viable fashion." In this case, the scientist following his curiosity had at least one eye simultaneously on commercialization.
  • ...1 more annotation...
  • In their appeal for more funding for scientific research, Leshner and Cooper argued that: "Across society, we don't have to look far for examples of basic research that paid off." They cite the creation of Google as a prime example of such payoffs: "Larry Page and Sergey Brin, then a National Science Foundation [NSF] fellow, did not intend to invent the Google search engine. Originally, they were intrigued by a mathematical challenge ..." The appealing imagery of a scientist who simply follows his curiosity and then makes a discovery with a large societal payoff is part of the core mythology of post-World War II science policies. The mythology shapes how governments around the world organize, account for, and fund research. A large body of scholarship has critiqued postwar science policies and found that, despite many notable successes, the science policies that may have made sense in the middle of the last century may need updating in the 21st century. In short, investments in "basic research" are not enough. Benoit Godin has asserted (PDF) that: "The problem is that the academic lobby has successfully claimed a monopoly on the creation of new knowledge, and that policy makers have been persuaded to confuse the necessary with the sufficient condition that investment in basic research would by itself necessarily lead to successful applications." Or as Leshner and Cooper declare in The Washington Post: "Federal investments in R&D have fueled half of the nation's economic growth since World War II."

    Can computers learn to read? We think so. "Read the Web" is a research project that attempts to create a computer system that learns over time to read the web. Since January 2010, our computer system called NELL (Never-Ending Language Learner) has been running continuously, attempting to perform two tasks each day: First, it attempts to "read," or extract facts from text found in hundreds of millions of web pages (e.g., playsInstrument(George_Harrison, guitar)). Second, it attempts to improve its reading competence, so that tomorrow it can extract more facts from the web, more accurately. So far, NELL has accumulated over 15 million candidate beliefs by reading the web, and it is considering these at different levels of confidence. NELL has high confidence in 928,295 of these beliefs - these are displayed on this website. It is not perfect, but NELL is learning. You can track NELL's progress below or @cmunell on Twitter, browse and download its knowledge base, read more about our technical approach, or join the discussion group.

Particle Energy Climate Change Health

shared by Weiye Loh on 29 Apr 12 - No Cached
  • according to the United Nations’ Intergovernmental Panel on Climate Change, the cooling effect of white particles may counteract as much as about half of the warming effect of carbon dioxide. So, if all white particles were removed from the atmosphere, global warming would increase considerably.CommentsView/Create comment on this paragraphThe dilemma is that all particles, whether white or black, constitute a serious problem for human health. Every year, an estimated two million people worldwide die prematurely, owing to the effects of breathing polluted air. Furthermore, sulfur-rich white particles contribute to the acidification of soil and water.
  • Naturally, measures targeting soot and other short-lived particles must not undermine efforts to reduce CO2 emissions. In the long term, emissions of CO2 and other long-lived greenhouse gases constitute the main problem. But a reduction in emissions of soot (and other short-lived climate pollutants) could alleviate the pressures on the climate in the coming decades.
  • what do we do about white particles? How do we weigh improved health and reduced mortality rates for hundreds of thousands of people against the serious consequences of global warming?CommentsView/Create comment on this paragraphIt is difficult to imagine that any country’s officials would knowingly submit their population to higher health risks by not acting to reduce white particles solely because they counteract global warming. On the contrary, sulfur emissions have been reduced over the last few decades in both Europe and North America, owing to a desire to promote health and counter acidification; and China, too, seems to be taking measures to reduce sulfur emissions and improve the country’s terrible air quality. But, in other parts of the world where industrialization is accelerating, sulfur emissions continue to increase.

  • Nobel laureate Paul Crutzen has suggested another solution: manipulate the climate by releasing white sulfur particles high up in the stratosphere, where they would remain for several years, exerting a proven cooling effect on Earth’s climate without affecting human health. In 1991, the eruption of Mount Pinatubo in the Philippines created a haze of sulfur in the higher atmosphere that cooled the entire planet approximately half a degree Celsius for two years afterwards.

    Particle emissions into Earth's atmosphere affect both human health and the climate. So we should limit them, right? For health reasons, yes, we should indeed do that; but, paradoxically, limiting such emissions would cause global warming to increase

Journalism Polarisation Fragmentation Politics Bias Postmodernism

shared by Weiye Loh on 07 Mar 12 - No Cached
  • Of course, not everything in the mainstream media is always true. Mistakes are made. News organizations have political biases, sometimes reflecting the views and interests of their owners. But high-quality journalism has always relied on its reputation for probity. Editors, as well as reporters, at least tried to get the facts right. That is why people read Le Monde, The New York Times, or, indeed, the Washington Post. Filtering nonsense was one of their duties – and their main selling point.
  • It is unlikely that Rick Santorum, or many of his followers, have read any post-modern theorists. Santorum, after all, recently called Obama a “snob” for claiming that all Americans should be entitled to a college education. So he must surely loath writers who represent everything that the Tea Party and other radical right-wingers abhor: the highly educated, intellectual, urban, secular, and not always white. These writers are the left-wing elite, at least in academia.
  • But, as so often happens, ideas have a way of migrating in unexpected ways. The blogger who dismissed The Washington Post’s corrections of Santorum’s fictional portrayal of the Netherlands expressed himself like a perfect post-modernist. The most faithful followers of obscure leftist thinkers in Paris, New York, or Berkeley are the most reactionary elements in the American heartland. Of course, if this were pointed out to them, they would no doubt dismiss it as elitist propaganda.

  • As the virtual world expands, so, too, do breaches of trust and misuse of personal data. Surveillance has increased public unease – and even paranoia – about state agencies. Private companies that trade in personal data have incited the launch of a “reclaim privacy” movement. As one delegate at a recent World Economic Forum debate, noted: “The more connected we have become, the more privacy we have given up.”
  • Now that our personal data have become such a valuable asset, companies are coming under increasing pressure to develop online business models that protect rather than exploit users’ private information. In particular, Internet users want to stop companies befuddling their customers with convoluted and legalistic service agreements in order to extract and sell their data.

  • University of Michigan in Ann Arbor
  • Vipul Bhrigu, a former postdoc at the university's Comprehensive Cancer Center, wears a dark-blue three-buttoned suit and a pinched expression as he cups his pregnant wife's hand in both of his. When Pollard Hines calls Bhrigu's case to order, she has stern words for him: "I was inclined to send you to jail when I came out here this morning."
  • Bhrigu, over the course of several months at Michigan, had meticulously and systematically sabotaged the work of Heather Ames, a graduate student in his lab, by tampering with her experiments and poisoning her cell-culture media. Captured on hidden camera, Bhrigu confessed to university police in April and pleaded guilty to malicious destruction of personal property, a misdemeanour that apparently usually involves cars: in the spaces for make and model on the police report, the arresting officer wrote "lab research" and "cells". Bhrigu has said on multiple occasions that he was compelled by "internal pressure" and had hoped to slow down Ames's work. Speaking earlier this month, he was contrite. "It was a complete lack of moral judgement on my part," he said.
  • ...16 more annotations...
  • Bhrigu's actions are surprising, but probably not unique. There are few firm numbers showing the prevalence of research sabotage, but conversations with graduate students, postdocs and research-misconduct experts suggest that such misdeeds occur elsewhere, and that most go unreported or unpoliced. In this case, the episode set back research, wasted potentially tens of thousands of dollars and terrorized a young student. More broadly, acts such as Bhrigu's — along with more subtle actions to hold back or derail colleagues' work — have a toxic effect on science and scientists. They are an affront to the implicit trust between scientists that is necessary for research endeavours to exist and thrive.
  • Despite all this, there is little to prevent perpetrators re-entering science.
  • federal bodies that provide research funding have limited ability and inclination to take action in sabotage cases because they aren't interpreted as fitting the federal definition of research misconduct, which is limited to plagiarism, fabrication and falsification of research data.
  • In Bhrigu's case, administrators at the University of Michigan worked with police to investigate, thanks in part to the persistence of Ames and her supervisor, Theo Ross. "The question is, how many universities have such procedures in place that scientists can go and get that kind of support?" says Christine Boesz, former inspector-general for the US National Science Foundation in Arlington, Virginia, and now a consultant on scientific accountability. "Most universities I was familiar with would not necessarily be so responsive."
  • Some labs are known to be hyper-competitive, with principal investigators pitting postdocs against each other. But Ross's lab is a small, collegial place. At the time that Ames was noticing problems, it housed just one other graduate student, a few undergraduates doing projects, and the lab manager, Katherine Oravecz-Wilson, a nine-year veteran of the lab whom Ross calls her "eyes and ears". And then there was Bhrigu, an amiable postdoc who had joined the lab in April 2009.
  • Some people whom Ross consulted with tried to convince her that Ames was hitting a rough patch in her work and looking for someone else to blame. But Ames was persistent, so Ross took the matter to the university's office of regulatory affairs, which advises on a wide variety of rules and regulations pertaining to research and clinical care. Ray Hutchinson, associate dean of the office, and Patricia Ward, its director, had never dealt with anything like it before. After several meetings and two more instances of alcohol in the media, Ward contacted the department of public safety — the university's police force — on 9 March. They immediately launched an investigation — into Ames herself. She endured two interrogations and a lie-detector test before investigators decided to look elsewhere.
  • At 4:00 a.m. on Sunday 18 April, officers installed two cameras in the lab: one in the cold room where Ames's blots had been contaminated, and one above the refrigerator where she stored her media. Ames came in that day and worked until 5:00 p.m. On Monday morning at around 10:15, she found that her medium had been spiked again. When Ross reviewed the tapes of the intervening hours with Richard Zavala, the officer assigned to the case, she says that her heart sank. Bhrigu entered the lab at 9:00 a.m. on Monday and pulled out the culture media that he would use for the day. He then returned to the fridge with a spray bottle of ethanol, usually used to sterilize lab benches. With his back to the camera, he rummaged through the fridge for 46 seconds. Ross couldn't be sure what he was doing, but it didn't look good. Zavala escorted Bhrigu to the campus police department for questioning. When he told Bhrigu about the cameras in the lab, the postdoc asked for a drink of water and then confessed. He said that he had been sabotaging Ames's work since February. (He denies involvement in the December and January incidents.)
  • Misbehaviour in science is nothing new — but its frequency is difficult to measure. Daniele Fanelli at the University of Edinburgh, UK, who studies research misconduct, says that overtly malicious offences such as Bhrigu's are probably infrequent, but other forms of indecency and sabotage are likely to be more common. "A lot more would be the kind of thing you couldn't capture on camera," he says. Vindictive peer review, dishonest reference letters and withholding key aspects of protocols from colleagues or competitors can do just as much to derail a career or a research project as vandalizing experiments. These are just a few of the questionable practices that seem quite widespread in science, but are not technically considered misconduct. In a meta-analysis of misconduct surveys, published last year (D. Fanelli PLoS ONE 4, e5738; 2009), Fanelli found that up to one-third of scientists admit to offences that fall into this grey area, and up to 70% say that they have observed them.
  • Some say that the structure of the scientific enterprise is to blame. The big rewards — tenured positions, grants, papers in stellar journals — are won through competition. To get ahead, researchers need only be better than those they are competing with. That ethos, says Brian Martinson, a sociologist at HealthPartners Research Foundation in Minneapolis, Minnesota, can lead to sabotage. He and others have suggested that universities and funders need to acknowledge the pressures in the research system and try to ease them by means of education and rehabilitation, rather than simply punishing perpetrators after the fact.
  • Bhrigu says that he felt pressure in moving from the small college at Toledo to the much bigger one in Michigan. He says that some criticisms he received from Ross about his incomplete training and his work habits frustrated him, but he doesn't blame his actions on that. "In any kind of workplace there is bound to be some pressure," he says. "I just got jealous of others moving ahead and I wanted to slow them down."
  • At Washtenaw County Courthouse in July, having reviewed the case files, Pollard Hines delivered Bhrigu's sentence. She ordered him to pay around US$8,800 for reagents and experimental materials, plus $600 in court fees and fines — and to serve six months' probation, perform 40 hours of community service and undergo a psychiatric evaluation.
  • But the threat of a worse sentence hung over Bhrigu's head. At the request of the prosecutor, Ross had prepared a more detailed list of damages, including Bhrigu's entire salary, half of Ames's, six months' salary for a technician to help Ames get back up to speed, and a quarter of the lab's reagents. The court arrived at a possible figure of $72,000, with the final amount to be decided upon at a restitution hearing in September.
  • Ross, though, is happy that the ordeal is largely over. For the month-and-a-half of the investigation, she became reluctant to take on new students or to hire personnel. She says she considered packing up her research programme. She even questioned her own sanity, worrying that she was the one sabotaging Ames's work via "an alternate personality". Ross now wonders if she was too trusting, and urges other lab heads to "realize that the whole spectrum of humanity is in your lab. So, when someone complains to you, take it seriously."
  • She also urges others to speak up when wrongdoing is discovered. After Bhrigu pleaded guilty in June, Ross called Trempe at the University of Toledo. He was shocked, of course, and for more than one reason. His department at Toledo had actually re-hired Bhrigu. Bhrigu says that he lied about the reason he left Michigan, blaming it on disagreements with Ross. Toledo let Bhrigu go in July, not long after Ross's call.
  • Now that Bhrigu is in India, there is little to prevent him from getting back into science. And even if he were in the United States, there wouldn't be much to stop him. The National Institutes of Health in Bethesda, Maryland, through its Office of Research Integrity, will sometimes bar an individual from receiving federal research funds for a time if they are found guilty of misconduct. But Bhigru probably won't face that prospect because his actions don't fit the federal definition of misconduct, a situation Ross finds strange. "All scientists will tell you that it's scientific misconduct because it's tampering with data," she says.
  • Ames says that the experience shook her trust in her chosen profession. "I did have doubts about continuing with science. It hurt my idea of science as a community that works together, builds upon each other's work and collaborates."

Piracy Open Source Android

shared by Weiye Loh on 29 Sep 10 - No Cached
  • Some have argued that piracy is rampant in those countries where the online Android Market is not yet available. But a recent KeyesLabs research project suggests that may not be true. KeyesLabs created a rough methodology to track total downloads of its apps, determine which ones were pirated, and the location of the end users. The results were posted in August, along with a “heat map” showing pirate activity. 
  • In July 2010, Google announced the Google Licensing Service, available via Android Market. Applications can include the new License Verification Library (LVL). “At run time, with the inclusion of a set of libraries provided by us, your application can query the Android Market licensing server to determine the license status of your users,” according to a blog post by Android engineer Eric Chu. “It returns information on whether your users are authorized to use the app based on stored sales records.”
  • Justin Case, at the Android Police Web site, dissected the LVL. “A minor patch to an application employing this official, Google-recommended protection system will render it completely worthless,” he concluded.
  • ...2 more annotations...
  • In response, Google has promised continued improvements and outlined a multipronged strategy around the new licensing service to make piracy much harder. “A determined attacker who’s willing to disassemble and reassemble code can eventually hack around the service,” acknowledged Android engineer Trevor Johns in a recent blog post.  But developers can make their work much harder by combining a cluster of techniques, he counsels: obfuscating code, modifying the licensing library to protect against common cracking techniques, designing the app to be tamper-resistant, and offloading license validation to a trusted server.
  • Gareau isn’t quite as convinced of the benefits of code obfuscation, though he does make use of it. He’s taken several other steps to protect his software work. One is providing a free trial version, which allows only a limited amount of data but is otherwise fully-featured. The idea: Let customers prove that the app will do everything they want, and they may be more willing to pay for it. He also provides a way to detect whether the app has been tampered with, for example, by removing the licensing checks. If yes, the app can be structured to stop working or behave erratically.

Facebook Data Visualization World

shared by Weiye Loh on 15 Dec 10 - No Cached
  • I was interested in seeing how geography and political borders affected where people lived relative to their friends. I wanted a visualization that would show which cities had a lot of friendships between them.
  • I began by taking a sample of about ten million pairs of friends from Apache Hive, our data warehouse. I combined that data with each user's current city and summed the number of friends between each pair of cities. Then I merged the data with the longitude and latitude of each city. At that point, I began exploring it in R, an open-source statistics environment. As a sanity check, I plotted points at some of the latitude and longitude coordinates. To my relief, what I saw was roughly an outline of the world. Next I erased the dots and plotted lines between the points. After a few minutes of rendering, a big white blob appeared in the center of the map. Some of the outer edges of the blob vaguely resembled the continents, but it was clear that I had too much data to get interesting results just by drawing lines. I thought that making the lines semi-transparent would do the trick, but I quickly realized that my graphing environment couldn't handle enough shades of color for it to work the way I wanted.
  • Instead I found a way to simulate the effect I wanted. I defined weights for each pair of cities as a function of the Euclidean distance between them and the number of friends between them. Then I plotted lines between the pairs by weight, so that pairs of cities with the most friendships between them were drawn on top of the others. I used a color ramp from black to blue to white, with each line's color depending on its weight. I also transformed some of the lines to wrap around the image, rather than spanning more than halfway around the world. View high-res (3.8MB)

  • The blob had turned into a surprisingly detailed map of the world. Not only were continents visible, certain international borders were apparent as well. What really struck me, though, was knowing that the lines didn't represent coasts or rivers or political borders, but real human relationships. Each line might represent a friendship made while travelling, a family member abroad, or an old college friend pulled away by the various forces of life.

Religion Evolution Science

shared by Weiye Loh on 08 Mar 10 - Cached
  • Even before I started writing Evolution: How We and All Living Things Came to Be I knew that it would very briefly mention religion, make a mild assertion that religious questions are out of scope for science, and move on. I knew this was likely to provoke blow-back from some in the atheist community, and I knew mentioning that blow-back in my recent post “The Standard Pablum — Science and Atheism” would generate more.
  • Still, I was surprised by the quantity of the responses to the blog post (208 comments as of this moment, many of them substantial letters), and also by the fierceness of some of those responses. For example, according to one poster, “you not only pandered, you lied. And even if you weren’t lying, you lied.” (Several took up this “lying” theme.) Another, disappointed that my children’s book does not tell a general youth audience to look to “secular humanism for guidance,” declared  that “I’d have to tear out that page if I bought the book.”
  • I don’t mean to suggest that there are not points of legitimate disagreement in the mix — there are, many of them stated powerfully. There are also statements of support, vigorous debate, and (for me at least) a good deal of food for thought. I invite anyone to browse the thread, although I’d urge you to skim some of it. (The internet is after all a hyperbole-generating machine.)

  • I lack any belief in any deity. More than that, I am persuaded (by philosophical argument, not scientific evidence) to a high degree of confidence that gods and an afterlife do not exist.
  • do try to distinguish between my work as a science writer and skeptical activist on the one hand, and my personal opinions about religion and humanism on the other.
  • Atheism is a practical handicap for science outreach. I’m not naive about this, but I’m not cynical either. I’m a writer. I’m in the business of communicating ideas about science, not throwing up roadblocks and distractions. It’s good communication to keep things as clear, focused, and on-topic as possible.
  • Atheism is divisive for the skeptical community, and it distracts us from our core mandate. I was blunt about this in my 2007 essay “Where Do We Go From Here?”, writing, I’m both an atheist and a secular humanist, but it is clear to me that atheism is an albatross for the skeptical movement. It divides us, it distracts us, and it marginalizes us. Frankly, we can’t afford that. We need all the help we can get.
  • In What Do I Do Next? I urged skeptics to remember that there are many other skeptics who do hold or identify with some religion. Indeed, the modern skeptical movement is built partly on the work of people of faith (including giants like Harry Houdini and Martin Gardner). You don’t, after all, have to be against god to be against fraud.
  • In my Skeptical Inquirer article “The Paradoxical Future of Skepticism” I argued that skeptics must set aside the conceit that our goal is a cultural revolution or the dawning of a new Enlightenment. … When we focus on that distant, receding, and perhaps illusory goal, we fail to see the practical good we can do, the harm-reduction opportunities right in front of us. The long view subverts our understanding of the scale and hazard of paranormal beliefs, leading to sentiments that the paranormal is “trivial” or “played out.” By contrast, the immediate, local, human view — the view that asks “Will this help someone?” — sees obvious opportunities for every local group and grassroots skeptic to make a meaningful difference.
  • This practical argument, that skepticism can get more done if we keep our mandate tight and avoid alienating our best friends, seems to me an important one. Even so, it is not my main reason for arguing that atheism and skepticism are different projects.
  • In my opinion, Metaphysics and ethics are out of scope for science — and therefore out of scope for skepticism. This is by far the most important reason I set aside my own atheism when I put on my “skeptic” hat. It’s not that I don’t think atheism is rational — I do. That’s why I’m an atheist. But I know that I cannot claim scientific authority for a conclusion that science cannot test, confirm, or disprove. And so, I restrict myself as much as possible, in my role as a skeptic and science writer, to investigable claims. I’ve become a cheerleader for this “testable claims” criterion (and I’ll discuss it further in future posts) but it’s not a new or radical constriction of the scope of skepticism. It’s the traditional position occupied by skeptical organizations for decades.
  • In much of the commentary, I see an assumption that I must not really believe that testable paranormal and pseudoscientific claims (“I can read minds”) are different in kind from the untestable claims we often find at the core of religion (“god exists”). I acknowledge that many smart people disagree on this point, but I assure you that this is indeed what I think.
  • I’d like to call out one blogger’s response to my “Standard Pablum” post. The author certainly disagrees with me (we’ve discussed the topic often on Twitter), but I thank him for describing my position fairly: From what I’ve read of Daniel’s writings before, this seems to be a very consistent position that he has always maintained, not a new one he adopted for the book release. It appears to me that when Daniel says that science has nothing to say about religion, he really means it. I have nothing to say to that. It also appears to me that when he says skepticism is a “different project than atheism” he also means it.

  • you need to understand whether recent weather trends are extreme by historical standards. The Twentieth Century Reanalysis Project is the latest attempt to find out, using super-computers to generate a dataset of global atmospheric circulation from 1871 to the present. As it happens, the project's initial findings, published last month, show no evidence of an intensifying weather trend. "In the climate models, the extremes get more extreme as we move into a doubled CO2 world in 100 years," atmospheric scientist Gilbert Compo, one of the researchers on the project, tells me from his office at the University of Colorado, Boulder. "So we were surprised that none of the three major indices of climate variability that we used show a trend of increased circulation going back to 1871."
  • researchers have yet to find evidence of more-extreme weather patterns over the period, contrary to what the models predict. "There's no data-driven answer yet to the question of how human activity has affected extreme weather," adds Roger Pielke Jr., another University of Colorado climate researcher.
  • We do know that carbon dioxide and other gases trap and re-radiate heat. We also know that humans have emitted ever-more of these gases since the Industrial Revolution. What we don't know is exactly how sensitive the climate is to increases in these gases versus other possible factors—solar variability, oceanic currents, Pacific heating and cooling cycles, planets' gravitational and magnetic oscillations, and so on. Given the unknowns, it's possible that even if we spend trillions of dollars, and forgo trillions more in future economic growth, to cut carbon emissions to pre-industrial levels, the climate will continue to change—as it always has.

  • That's not to say we're helpless. There is at least one climate lesson that we can draw from the recent weather: Whatever happens, prosperity and preparedness help. North Texas's ice storm wreaked havoc and left hundreds of football fans stranded, cold, and angry. But thanks to modern infrastructure, 21st century health care, and stockpiles of magnesium chloride and snow plows, the storm caused no reported deaths and Dallas managed to host the big game on Sunday.

The Great Beyond: Indian government competition for better skin whiteners draws fire - 0 views

Capitalism Science Research Beauty

shared by Weiye Loh on 27 Feb 11 - No Cached
  • In December 2010 the Department of Science and Technology (DST) launched a monthly competition in association with Cincinnati-based Proctor & Gamble (P&G) to solicit innovative ideas from Indian researchers. Winners were promised a cash award of $1000 and possible commercialization of their ideas by P&G, which has a beauty business worth over US$10 billion in global sales. But the competition's first call - for skin whitening alternatives to hydroquinone, which is not approved for use in many places including the European Union - has prompted criticism from researchers who argue that such products help to propagate racist attitudes in the country. Meanwhile, the department's January challenge for cheaper alternatives to silicones in shampoos, lotions, fabric softeners, and other beauty products marketed by P&G has fared little better. The principal drawback of silicones is their expense and poor biodegradability but some researchers argue that India has more pressing issues for its scientists to address.
  • However, the current DST secretary Thirumalachari Ramasami disagrees. The DST-P&G Challenge of The Month is only a small part of the department's overall activities, he says. “It is not a priority project but a very minor programme compared to larger issues of national importance that we are concerned with,” Ramasami told Nature adding that his department has earmarked only Rs.50 million (US$1.1 million) in total for the project. He says it is absurd to accuse the DST of promoting beauty research at the expense of more important problems. “Tell me which challenging issue has been ignored by DST?” he asks.

Cancer Evolution Life

  • astrobiologists, working with oncologists in the US, have suggested that cancer resembles ancient forms of life that flourished between 600 million and 1 billion years ago.
  • Read more about what this discovery means for cancer research.
  • The genes that controlled the behaviour of these early multicellular organisms still reside within our own cells, managed by more recent genes that keep them in check.It's when these newer controlling genes fail that the older mechanisms take over, and the cell reverts to its earlier behaviours and grows out of control.

  • The new theory, published in the journal Physical Biology, has been put forward by two leading figures in the world of cosmology and astrobiology: Paul Davies, director of the Beyond Center for Fundamental Concepts in Science, Arizona State University; and Charles Lineweaver, from the Australian National University.
  • According to Lineweaver, this suggests that cancer is an atavism, or an evolutionary throwback.
  • In the paper, they suggest that a close look at cancer shows similarities with early forms of multicellular life.
  • “Unlike bacteria and viruses, cancer has not developed the capacity to evolve into new forms. In fact, cancer is better understood as the reversion of cells to the way they behaved a little over one billion years ago, when humans were nothing more than loose-knit colonies of only partially differentiated cells. “We think that the tumours that develop in cancer patients today take the same form as these simple cellular structures did more than a billion years ago,” he said.
  • One piece of evidence to support this theory is that cancers appear in virtually all metazoans, with the notable exception of the bizarre naked mole rat."This quasi-ubiquity suggests that the mechanisms of cancer are deep-rooted in evolutionary history, a conjecture that receives support from both paleontology and genetics," they write.
  • the genes that controlled this early multi-cellular form of life are like a computer operating system's 'safe mode', and when there are failures or mutations in the more recent genes that manage the way cells specialise and interact to form the complex life of today, then the earlier level of programming takes over.
  • Their notion is in contrast to a prevailing theory that cancer cells are 'rogue' cells that evolve rapidly within the body, overcoming the normal slew of cellular defences.
  • However, Davies and Lineweaver point out that cancer cells are highly cooperative with each other, if competing with the host's cells. This suggests a pre-existing complexity that is reminiscent of early multicellular life.
  • cancers' manifold survival mechanisms are predictable, and unlikely to emerge spontaneously through evolution within each individual in such a consistent way.
  • The good news is that this means combating cancer is not necessarily as complex as if the cancers were rogue cells evolving new and novel defence mechanisms within the body.Instead, because cancers fall back on the same evolved mechanisms that were used by early life, we can expect them to remain predictable, thus if they're susceptible to treatment, it's unlikely they'll evolve new ways to get around it.
  • If the atavism hypothesis is correct, there are new reasons for optimism," they write.

The Medium Is Not The Message: 3 Handwritten Newspapers | Brain Pickings - 0 views

  • Handwritten newspapers.

  • Since 1927, The Musalman has been quietly churning out its evening edition of four pages, all of which hand-written by Indian calligraphers in the shadow of the Wallajah Mosque in the city of Chennai. According to Wired, it might just be the last remaining hand-written newspaper in the world. It’s also India’s oldest daily newspaper in Urdu, the Hindustani language typically spoken by Muslims in South Asia. The Musalman: Preservation of a Dream is wonderful short film by Ishani K. Dutta, telling the story of the unusual publication and its writers’ dedication to the ancient art of Urdu calligraphy.

  • I mentioned a fascinating reversal of the-medium-is-the-message as one Japanese newspaper reverted to hand-written editions once the earthquake-and-tsunami disaster destroyed all power in the city of Ishinomaki in Miyagi Prefecture. For the next six days, the editors of the Ishinomaki Hibi Shimbun “printed” the daily newspaper’s disaster coverage the only way possible: By hand, in pen and paper. Using flashlights and marker pens, the reporters wrote the stories on poster-size paper and pinned the dailies to the entrance doors of relief centers around the city. Six staffers collected stories, which another three digested, spending an hour and a half per day composing the newspapers by hand.

    Minuscule literacy rates and prevailing poverty may not be conditions particularly conducive to publishing entrepreneurship, but they were no hindrance for Monrovia's The Daily Talk, a clever concept by Alfred Sirleaf that reaches thousands of Liberians every day by printing just once copy. That copy just happens to reside on a large blackboard on the side of one of the capital's busiest roads. Sirleaf started the project in 2000, at the peak of Liberia's civil war, but its cultural resonance and open access sustained it long after the war was over. To this day, he runs this remarkable one-man show as the editor, reporter, production manager, designer, fact-checker and publicist of The Daily Talk. For an added layer of thoughtfulness and sophistication, Sirleaf uses symbols to indicate specific topics for those who struggle to read. The common man in society can't afford a newspaper, can't afford to buy a generator to get on the internet - you know, power shortage - and people are caught up in a city where they have no access to information. And all of these things motivated me to come up with a kind of free media system for people to get informed." ~ Alfred Sirleaf

    can such hoaxes be beneficial? If a Western audience was in fact impelled to learn more about the social woes in Syria, is this a net gain for society in general? Should such well-intentioned projects be condoned, even perhaps emulated in certain ways if deemed an effective educational tool? Could we use this format - a narrative-driven account of important far-flung events that allows audience a portal into such events that may be more engaging than typical AP newswire reportage? People tend to connect better to emotion-filled story arcs than recitation of facts, after all. Perhaps instead of merely piling on MacMaster, we can learn something from his communication strategy …

Morality Relativism Ethics

shared by Weiye Loh on 18 Jun 11 - No Cached
  • Although this view of ethics has often been challenged, many of the objections have come from religious thinkers who appealed to God’s commands. Such arguments have limited appeal in the largely secular world of Western philosophy. Other defenses of objective truth in ethics made no appeal to religion, but could make little headway against the prevailing philosophical mood.
  • Many people assume that rationality is always instrumental: reason can tell us only how to get what we want, but our basic wants and desires are beyond the scope of reasoning. Not so, Parfit argues. Just as we can grasp the truth that 1 + 1 = 2, so we can see that I have a reason to avoid suffering agony at some future time, regardless of whether I now care about, or have desires about, whether I will suffer agony at that time. We can also have reasons (though not always conclusive reasons) to prevent others from suffering agony. Such self-evident normative truths provide the basis for Parfit’s defense of objectivity in ethics.
  • One major argument against objectivism in ethics is that people disagree deeply about right and wrong, and this disagreement extends to philosophers who cannot be accused of being ignorant or confused. If great thinkers like Immanuel Kant and Jeremy Bentham disagree about what we ought to do, can there really be an objectively true answer to that question? Parfit’s response to this line of argument leads him to make a claim that is perhaps even bolder than his defense of objectivism in ethics. He considers three leading theories about what we ought to do – one deriving from Kant, one from the social-contract tradition of Hobbes, Locke, Rousseau, and the contemporary philosophers John Rawls and T.M. Scanlon, and one from Bentham’s utilitarianism – and argues that the Kantian and social-contract theories must be revised in order to be defensible.

  • he argues that these revised theories coincide with a particular form of consequentialism, which is a theory in the same broad family as utilitarianism. If Parfit is right, there is much less disagreement between apparently conflicting moral theories than we all thought. The defenders of each of these theories are, in Parfit’s vivid phrase, “climbing the same mountain on different sides.”
  • Parfit’s real interest is in combating subjectivism and nihilism. Unless he can show that objectivism is true, he believes, nothing matters.
  • When Parfit does come to the question of “what matters,” his answer might seem surprisingly obvious. He tells us, for example, that what matters most now is that “we rich people give up some of our luxuries, ceasing to overheat the Earth’s atmosphere, and taking care of this planet in other ways, so that it continues to support intelligent life.” Many of us had already reached that conclusion. What we gain from Parfit’s work is the possibility of defending these and other moral claims as objective truths.

    Can moral judgments be true or false? Or is ethics, at bottom, a purely subjective matter, for individuals to choose, or perhaps relative to the culture of the society in which one lives? We might have just found out the answer. Among philosophers, the view that moral judgments state objective truths has been out of fashion since the 1930's, when logical positivists asserted that, because there seems to be no way of verifying the truth of moral judgments, they cannot be anything other than expressions of our feelings or attitudes. So, for example, when we say, "You ought not to hit that child," all we are really doing is expressing our disapproval of your hitting the child, or encouraging you to stop hitting the child. There is no truth to the matter of whether or not it is wrong for you to hit the child.
