Biology's Holy Grail: The Species And Its Controversial Recent History | IFLScience - 1 views

  • And, the basic unit of taxonomy – ‘the species’ – remains an elusive and controversial concept despite its fundamental importance to science. Yet, few people outside of biology and philosophy realise that ‘the species’ has been at the centre of a major controversy in science for much of the last 50 years.
  • Taxonomy is a fundamental or ‘enabling’ science that underpins all of biology and its many related fields including medical research.
  • • How does the species category compare with other scientific groups or types of things like say the chemical elements? • Does it play the same kind of role in science – conveying the same sorts of information and allowing us to make predictions about nature? • What’s the best, most objective, way to recognise a species?

  • So, it turns out we’ve all been cheated by the textbooks we read in high school or university. Short-changed by our science teachers and biology lecturers.

Remembering a Crime That You Didn't Commit - The New Yorker - 1 views

  • Earlier this year, two forensic psychologists—Julia Shaw, of the University of Bedfordshire, and Stephen Porter, of the University of British Columbia—upped the ante. Writing in the January issue of the journal Psychological Science, they described a method for implanting false memories, not of getting lost in childhood but of committing a crime in adolescence. They modelled their work on Loftus’s, sending questionnaires to each of their participant’s parents to gather background information. (Any past run-ins with the law would eliminate a student from the study.) Then they divided the students into two groups and told each a different kind of false story. One group was prompted to remember an emotional event, such as getting attacked by a dog. The other was prompted to remember a crime—an assault, for example—that led to an encounter with the police. At no time during the experiments were the participants allowed to communicate with their parents.
  • What Shaw and Porter found astonished them. “We thought we’d have something like a thirty-per-cent success rate, and we ended up having over seventy,” Shaw told me. “We only had a handful of people who didn’t believe us.” After three debriefing sessions, seventy-six per cent of the students claimed to remember the false emotional event; nearly the same amount—seventy per cent—remembered the fictional crime. Shaw and Porter hadn’t put undue stress on the students; in fact, they had treated them in a friendly way. All it took was a suggestion from an authoritative source, and the subjects’ imaginations did the rest. As Münsterberg observed of the farmer’s son, the students seemed almost eager to self-incriminate.
  • Kassin cited the example of Martin Tankleff, a high-school senior from Long Island who, in 1988, awoke to find hIs parents bleeding on the floor. Both had been repeatedly stabbed; hIs mother was dead and hIs father was dying. He called the police. Later, at the station, he was harshly interrogated. For five hours, Tankleff resIsted. Finally, an officer told him that hIs father had regained consciousness at the hospital and named him as the killer. (In truth, the father died without ever waking.) Overwhelmed by the news, Tankleff took responsibility, saying that he must have blacked out and killed hIs parents unwittingly. A jury convicted him of murder. He spent seventeen years in prIson before the real murderers were found. Kassin condemns the practice of lying to suspects, which Is illegal in many countries but not here. The American court system, he said, should address it. “Lying puts innocent people at rIsk, and there’s a hundred years of psychology to show it,” he said.

How Culture Shapes Our Senses - NYTimes.com - 2 views

  • In recent years anthropologists have begun to point out that sensory perception is culturally specific.
  • Recently, a team of anthropologists and psychologists at the Max Planck Institute for Psycholinguistics and Radboud University, both in Nijmegen, the Netherlands, set out to discover how language and culture affected sensory awareness. Under the leadership of Asifa Majid and Stephen C. Levinson, they made up a kit of systematic stimuli for the traditional five senses: for sight, color chips and geometric forms; for hearing, pitch, amplitude and rhythm variations; for smell, a set of scratch-and-sniff cards; and so forth. They took these kits to over 20 cultural groups around the world. Their results upend some of our basic assumptions.

When Philosophy Lost Its Way - The New York Times - 0 views

  • Having adopted the same structural form as the sciences, it’s no wonder philosophy fell prey to physics envy and feelings of inadequacy. Philosophy adopted the scientific modus operandi of knowledge production, but failed to match the sciences in terms of making progress in describing the world. Much has been made of this inability of philosophy to match the cognitive success of the sciences. But what has passed unnoticed is philosophy’s all-too-successful aping of the institutional form of the sciences. We, too, produce research articles. We, too, are judged by the same coin of the realm: peer-reviewed products. We, too, develop sub-specializations far from the comprehension of the person on the street. In all of these ways we are so very “scientific.”

Should a Sibling Be Told She's Adopted? - The New York Times - 0 views

  • My sister is the greatest blessing in my life. My parents and I were at the hospital when her birth mother went into labor, so she has been with us for her entire life. My parents never told her that she was adopted, and they asked me not to say anything. They planned on telling her when she was old enough to understand, but they kept putting it off. They know that I believe they have done her a serious disservice.
  • I think she suspects she’s different. She asks me sometimes why she’s so much shorter than the rest of us, for example. I do my best to deflect her questions, but it hurts every time. My sister and I are very close, and we see each other often. Keeping this lie feels like a giant burden, but, at this point, I don’t know that it would do her any good to know the truth. She was recently diagnosed with bipolar disorder and has been working hard to keep her life balanced. Finding out now that she’s adopted could throw her into a depression. I fear, however, that with the mail-in DNA tests available these days, or should a medical emergency arise, she’ll find out the truth and she won’t forgive me.

BBC - Earth - Black holes made simple with Stephen Hawking - 1 views

  • Fact can be stranger than fiction. This is especially true of black holes, as Prof Stephen Hawking explains.For instance as soon as you entered the black hole, reality would split in two. "In one, you would be instantly incinerated, and in the other you would plunge on into the black hole utterly unharmed," as we have previously explored.In the 2016 Reith lectures broadcast on BBC Radio 4, Prof Hawking further examines and challenges the latest scientific thinking about black holes.

Picasso = Genius: This algorithm can judge "creativity" in art as well as the experts - 1 views

  •  
    Art is seen as unquantifiable. Great paintings are creative forces that transcend their brush strokes, colors, and compositions. They can't be reduced to mere data, analyzed, and ranked by their creativity. Two computer scientists at Rutgers University respectfully disagree. Ahmed Elgammal and Babak Saleh created an algorithm that they say measures the originality and influence of artworks by using...

Banksy protest artwork unveiled in New York - BBC News - 2 views

  • Provocative artist Banksy has revealed a 20m high artwork in New York to draw attention to the imprisonment of Zehra Dogan, a Kurdish painter from Turkey.His image of her behind bars depicts the last bar as a pencil, and next to the mural is a call for her release. Dogan was jailed for two years and nine months last year in Turkey, for her painting of the Kurdish town Nusaybin. Her picture, copied from a newspaper photograph, showed the town reduced to rubble during conflict.

Do 'Fast and Furious' Movies Cause a Rise in Speeding? - The New York Times - 1 views

  • Does bad behavior in movies or other media lead people to behave badly? There’s plenty of research on the link between onscreen media and risky behaviors like unprotected sex, binge drinking, fast driving and even violence. One large meta-analysis of such studies concluded that exposure to risk-glorifying media is associated with risky behaviors by people who consume that media. But causality issues plague most studies in this area: People who engage in risky behaviors may prefer to consume risk-glorifying media. These studies also tend to measure attitudes in controlled lab settings rather than in real life.

Banksy Finds a Canvas and a New Fanbase in Gaza's Ruins - NYTimes.com - 1 views

  • GAZA — Very little of Abu Shadi Shenbari’s family home remains in Beit Hanoun, in the northern Gaza Strip. Only a concrete bathroom wall was left standing when Israeli forces flattened the neighborhood near the border with Israel during the war with Hamas last summer.Though Mr. Shenbari had all but abandoned that last panel of erect concrete, in recent days he began building a wood and wire-mesh fort with a flimsy nylon roof to protect the bombed-out bathroom wall, which Is now home to a 10-foot-tall depiction of a kitten.The spray-painted mural was created by the elusive BritIsh graffiti artIst Banksy, who slipped in and out of Gaza in February, leaving hIs mark on three slabs of rubble left from Israel’s 50-day fight with Hamas, the Islamic group that controls Gaza.

When behavioral economics meets a $700M Powerball jackpot - 2 views

  • Business Insider went out onto the streets of NYC and tried to buy people’s just-purchased Powerball tickets ahead of the $700 million drawing. They did not get many takers, even when offering twice the price they paid (which meant they could just go and buy double the number of tickets and slash their odds of winning). The video says this is an example of regret avoidance.

When Whites Just Don't Get It, Part 6 - The New York Times - 1 views

  • Why do we discriminate? The big factor isn’t overt racism. Rather, it seems to be unconscious bias among whites who believe in equality but act in ways that perpetuate inequality.
  • That’s why it’s so important for whites to engage in these uncomfortable discussions of race, because we are (unintentionally) so much a part of the problem. It’s not that we’re evil, but that we’re human. The challenge is to recognize that unconscious bias afflicts us all — but that we just may be able to overcome it if we face it.
