South of the city of Singapore is an island called Sentosa. Sentosa has been converted into a tourist haven, and you can reach it by cable car. One of us suggested that we try talking to them using our fingers as tentacles. We wonder if anyone else has tried talking to the cuttlefish of Sentosa, or any other cuttlefish. Cuttlefish are predacious carnivorous cephalopods related to squid and octopus. Read about Komodo dragons! Published: 11/7/98.Updated: 3/10/01.

Compet' à la mangeoire Participez à la première expérience de Vigie-Manip’ ! Compet’ à la mangeoire est une expérience explore les choix de nourrissage des oiseaux des jardins en hiver, en fonction de la nourriture disponible et du nombre d'individus présents. Tout l'enjeu de l'expérience est de comprendre les jeux d’interactions entre les espèces d'oiseaux en fonction du contexte environnemental. © Laurent Zagni | laurentzagni.com Comment ça marche ? Le protocole consiste à compter les oiseaux présents sur deux mangeoires plateaux identiques (que l’on peut facilement construire soi-même) proposant une offre en nourriture différente (graines de tournesol, graines de niger…). Quand participer ? L’expérience peut être réalisée sur un balcon, une terrasse, un jardin privé ou public et recommencée autant de fois que le participant le souhaite entre le 18 novembre 2013 et le 15 mars 2014. Qui peut participer ? Tous les amateurs d’oiseaux sauvages ! Participer Compet' à la mangeoire - guide de terrain A lire aussi :
Weta minute - he's a wee 'un - Strange But True International media are calling it the biggest weta ever found, but New Zealand experts are urging them to get a sense of perspective. American researcher Mark Moffett fed a carrot to a giant weta on a recent visit to New Zealand's Little Barrier Island and the meeting has turned into major news in the Northern Hemisphere. Pictures of the weta, or wetapunga, and its carrot have featured on websites around the world with headings including, "World's biggest insect". The story has run in The Telegraph, The Daily Mail, The Sun, The Mirror, the Huffington Post and The Times of India. New Zealand insect expert, bug man Ruud Kleinpaste, a trustee of Little Barrier Island Supporters Trust, has played down the significance of the find. "There's nothing unusual to find these weta," Kleinpaste said, though he thought the publicity for the species could be a good thing. Kleinpaste said he saw wetapunga on Little Barrier Island every time he went there. - Herald on Sunday
Theory About the Theory Overview Meta-Theory: The Organismic Viewpoint Formal Theory: SDT’s 5 Mini-Theories Other Topics of Interest Applications References Overview People are centrally concerned with motivation -- how to move themselves or others to act. Self-Determination Theory (SDT) represents a broad framework for the study of human motivation and personality. The dynamics of psychological need support and need thwarting have been studied within families, classrooms, teams, organizations, clinics, and cultures using specific propositions detailed within SDT. Meta-Theory: The Organismic Viewpoint SDT is an organismic dialectical approach. Within SDT, the nutriments for healthy development and functioning are specified using the concept of basic psychological needs for autonomy, competence, and relatedness. Formal Theory: SDT’s Five Mini-Theories Cognitive Evaluation Theory (CET) concerns intrinsic motivation, motivation that is based on the satisfactions of behaving “for its own sake.”
Galaxy Zoo Parrot Prodigy May Grasp the Concept of Zero July 15, 2005 A new study suggests that some birds may have a better grasp of numbers than the average three-year-old child. Researchers have shown that an African gray parrot may comprehend the mathematical concept of zero—an abstract notion that human children rarely understand until around four years of age. The concept of zero is surprisingly difficult to grasp, even for people. "There is some understanding of nonexistence that seems to develop naturally, but the actual use of the term 'zero' seems to need to be taught," said comparative psychologist Irene Pepperberg. The idea of zero as a nonexistent quantity was not obvious to early human cultures, Pepperberg said. Researchers in the United States and Japan have previously shown that chimpanzees and possibly squirrel monkeys can comprehend zero when taught. Zero Sum Pepperberg's most recent research with Alex, co-authored with Brandeis graduate student Jesse D.
Plankton Portal Finding out about the astronomers who found the universe | Open Parachute Book review: The Day We Found the Universe by Marcia Bartusiak Price: US$11.53; NZ$20.82 Hardcover: 368 pagePublisher: Pantheon (April 7, 2009)Language: EnglishISBN-10: 0375424296ASIN: B005IUVQGY This is a great book – just the sort of history of science I enjoy. The title is apt. The big illusion the book shatters is the received story of how this happened through the work of Edwin Hubble. Island universes Marcia Bartusiak reveals that concepts of a larger universe go back a long way. As far back as the first century B.C., the Roman poet and philosopher Lucretius argued against a finite universe. ” whether certain cloudy spots, then being observed in the heavens in greater numbers, might be additional creations, bordering upon us but ’too remote for even our telescopes to reach,’ countless spheres with many ’Divine Centres.’ In 1755 Kant described nebular patches in the nighttime sky as: This, of course, radically reshaped how humans understood their place in the cosmos. “An odd bird”
Hovering on the Horizon The limb of the Earth is a work of beauty and a gift to science. When observed from space, the layers of the atmosphere remind us of the fragility of the cocoon that shelters life. That same view also allows scientists to detect the gases and particles that make up the different layers of our atmosphere. Astronauts aboard the International Space Station captured a bit of both in this digital photograph from July 31, 2011. Closest to Earth’s surface, the orange-red glow reveals the troposphere—the lowest, densest layer of atmosphere, and the one we live within. The different colors occur because the dominant gases and particles in each layer act as prisms, filtering out certain colors of light. A thin crescent of the Moon is illuminated by the Sun from below the horizon of the Earth. Instrument(s): ISS - Digital Camera
Icelanders approve their crowdsourced constitution — European technology news "Animal Language Article" Copyright 1995 The New York Times Company The New York Times June 6, 1995, Tuesday, Late Edition - Final SECTION: Section C; Page 1; Column 1; Science Desk LENGTH: 2199 words Chimp Talk Debate: Is It Really Language? By George Johnson PANBANISHA, a Bonobo chimpanzee who has become something of a star among animal language researchers, was strolling through the Georgia woods with a group of her fellow primates -- scientists at the Language Research Center at Georgia State University in Atlanta. Suddenly, the chimp pulled one of them aside. Grabbing a special keyboard of the kind used to teach severely retarded children to communicate, she repeatedly pressed three symbols -- "Fight," "Mad," "Austin" -- in various combinations. Austin is the name of another chimpanzee at the center. "Waa, waa, waa" said the chimpanzee, in what Dr. A decade and a half after the claims of animal language researchers were discredited as exaggerated self-delusions, Dr. Dr. But some philosophers, like Dr.
