A New Form of Stem-Cell Engineering Raises Ethical Questions - The New York Times - 0 views

  • As biological research races forward, ethical quandaries are piling up. In a report published Tuesday in the journal eLife, researchers at Harvard Medical School said it was time to ponder a startling new prospect: synthetic embryos.In recent years, scientists have moved beyond in vitro fertilization. They are starting to assemble stem cells that can organize themselves into embryolike structures.Soon, experts predict, they will learn how to engineer these cells into new kinds of tissues and organs. Eventually, they may take on features of a mature human being.

Why "Just Say No" Doesn't Work - Scientific American - 0 views

  • In an attempt to reduce these figures, substance abuse prevention programs often educate pupils regarding the perils of drug use, teach students social skills to resist peer pressure to experiment, and help young people feel that saying no is socially acceptable. All the approaches seem sensible on the surface, so policy makers, teachers and parents typically assume they work. Yet it turns out that approaches involving social interaction work better than the ones emphasizing education. That finding may explain why the most popular prevention program has been found to be ineffective—and may even heighten the use of some substances among teens.
  • Cuijpers reported that the most effective ones involve substantial amounts of interaction between instructors and students. They teach students the social skills they need to refuse drugs and give them opportunities to practice these skills with other students—for example, by asking students to play roles on both sides of a conversation about drugs, while instructors coach them about what to say and do. In addition, programs that work take into account the importance of behavioral norms

BBC World Service - More or Less, The death toll in Syria - 0 views

  •  
    As global leaders remain divided on whether to carry out a military strike against Syria in response to the apparent use of chemical weapons against its people, Tim Harford looks at the different claims made about how many people have been killed. The United States, the UK and France are sharing intelligence, but all quote different estimates of how many people they think died in the attack by Syrian President Bashar al-Assad's forces. Tim speaks to Kelly Greenhill, a professor of political science at Tufts University in the US, and co-author of Sex, Drugs and Body Counts about why the numbers vary so widely. And he speaks to Megan Price from the Human Rights Data Analysis Group, who has been trying to keep a tally of the deaths in Syria since the conflict began.

The Older Mind May Just Be a Fuller Mind - NYTimes.com - 0 views

  • Now comes a new kind of challenge to the evidence of a cognitive decline, from a decidedly digital quarter: data mining, based on theories of information processing. In a paper published in Topics in Cognitive Science, a team of linguistic researchers from the University of Tübingen in Germany used advanced learning models to search enormous databases of words and phrases. Since educated older people generally know more words than younger people, simply by virtue of having been around longer, the experiment simulates what an older brain has to do to retrieve a word. And when the researchers incorporated that difference into the models, the aging “deficits” largely disappeared.

There Are 177,147 Ways To Tie A Tie | Popular Science - 0 views

  •  
    "Mikael Vejdemo-Johansson, a mathematician in Stockholm, recently led a small team on a quest to discern how many tie knots are possible. Their results, uploaded to arXiv, say there are 177,147 different ways to tie the knot of a necktie. That is 177,062 more ways than were found in 1999 by Cambridge mathematicians Yong Mao and Thomas Fink, who arrived at 85 possible ways to tie a tie. Why the discrepancy?"

The Dangers of Certainty: A Lesson From Auschwitz - NYTimes.com - 1 views

  • The ascent of man was secured through scientific creativity. But unlike many of his more glossy and glib contemporary epigones, Dr. Bronowski was never reductive in his commitment to science. Scientific activity was always linked to artistic creation. For Bronowski, science and art were two neighboring mighty rivers that flowed from a common source: the human imagination. Newton and Shakespeare, Darwin and Coleridge, Einstein and Braque: all were interdependent facets of the human mind and constituted what was best and most noble about the human adventure.
  • For Dr. Bronowski, the moral consequence of knowledge is that we must never judge others on the basis of some absolute, God-like conception of certainty.
  • At this point, in the final minutes of the show, the scene suddenly shifts to Auschwitz, where many members of Bronowski’s family were murdered. Then this happened. Please stay with it. This short video from the show lasts only four minutes or so.[Video: Dr. Jacob Bronowski's argument against certainty, made at Auschwitz for his show "The Ascent of Man." Watch on YouTube.]It is, I am sure you agree, an extraordinary and moving moment. Bronowski dips his hand into the muddy water of a pond which contained the remains of his family members and the members of countless other families. All victims of the same hatred: the hatred of the other human being. By contrast, he says — just before the camera hauntingly cuts to slow motion — “We have to touch people.”

The Word For... : The New Yorker - 1 views

  •  
    "The word "neologism" dates to the seventeen-seventies, taken from Greek via French, meaning "new speech." But the practice of coining new words goes back to the beginning of language itself. It accelerated as culture accelerated, and by the nineteenth century conservative types were worried that industry and science were flooding the linguistic marketplace with all kinds of shoddy fad words, and that the language had to be protected from interlopers. Others embraced the dynamism. "

    "Kay Redfield Jamison is a clinical psychologist with a rare insight. She is a world leader in the study of bipolar (manic-depressive) illness, a condition that she herself has had since adolescence. As a highly regarded clinician with direct experience of the illness she treats, she has a special perspective on the debilitating nature of this psychiatric disorder and its seductive but disastrous highs, depressions and disordered thinking. She tells A.C.Grayling and an audience at Wellcome Collection in London about mania, creativity and the best medicine for an extraordinary condition."

I Had My DNA Picture Taken, With Varying Results - NYTimes.com - 0 views

  •  
    "So I decided to read the tea leaves of my DNA. I reasoned that it was worth learning painful information if it might help me avert future illness. Like others, I turned to genetic testing, but I wondered if I could trust the nascent field to give me reliable results. In recent years, a handful of studies have found substantial variations in the risks for common diseases predicted by direct-to-consumer companies. I set out to test the tests: Could three of them agree on me? The answers were eye-opening"

Why Nothing Is Truly Alive - NYTimes.com - 0 views

  • What is life? Science cannot tell us. Since the time of Aristotle, philosophers and scientists have struggled and failed to produce a precise, universally accepted definition of life. To compensate, modern textbooks point to characteristics that supposedly distinguish the living from the inanimate, the most important of which are organization, growth, reproduction and evolution. But there are numerous exceptions: both living things that lack some of the ostensibly distinctive features of life and inanimate things that have properties of the living.

Theory of mind and the belief in God. - Slate Magazine - 0 views

  • As a direct consequence of the evolution of the human social brain, and owing to the importance of our theory-of-mind skills in that process, we sometimes can't help but see intentions, desires, and beliefs in things that haven't even a smidgeon of a neural system. In particular, when inanimate objects do unexpected things, we sometimes reason about them just as we do for oddly behaving—or misbehaving—people. More than a few of us have kicked our broken-down vehicles in the sides and verbally abused our incompetent computers. Most of us stop short of actually believing these objects possess mental states—indeed, we would likely be hauled away to an asylum if we genuinely believed that they held malicious intent—but our emotions and behaviors toward such objects seem to betray our primitive, unconscious thinking: we act as though they're morally culpable for their actions.

And the Word of the Year Is... Selfie! : The New Yorker - 0 views

  • Hold on to your monocles, friends—the Oxford Dictionaries Word of the Year for 2013 is “selfie.” It’s an informal noun (plural: selfies) defined as “a photograph that one has taken of oneself, typically one taken with a smartphone or webcam and uploaded to a social media website.” It was first used in 2002, in an Australian online forum (compare the Australian diminutives “barbie” for barbecue and “firie” for firefighter), and it first appeared as a hashtag, #selfie, on Flickr, in 2004.
  • The word “selfie” is not yet in the O.E.D., but it is currently being considered for future inclusion; whether the word makes it into the history books is truly for the teens to decide. As Ben Zimmer wrote at Language Log, “Youth slang is the obvious source for much of our lexical innovation, like it or not.” And despite its cloying tone, that Oxford Dictionaries blog post from August does allude to the increasingly important distinction between “acronym“ and “initialism”—either of which may describe the expression “LOL,” depending if you pronounce it “lawl” or “ell-oh-ell.” The kids are going to be all right. Not “alright.” But all right.
