Twelve-year-old Aaron Zibricky, a member of the Lucky Clovers 4-H Club, entered his prize sheep, Star, in the 2005 Will County Fair in Illinois. Zibricky, who is diagnosed with autism, had worked and strived for this moment, putting in long hours feeding, cleaning and shearing the sheep and learning showmanship skills. No one was more elated at…

This paper discusses the evaluation of an informal science education project, The Birdhouse Network (TBN) of the Cornell Laboratory of Ornithology. The Elaboration Likelihood Model and the theory of Experiential Education were used as frameworks to analyse the impact of TBN on participants' attitudes toward science and the environment, on their…

This article summarizes the major categories of ethical violations encountered during submission, review, and publication of scientific articles. We discuss data fabrication and falsification, plagiarism, redundant and duplicate publication, conflict of interest, authorship, animal and human welfare, and reviewer responsibility. In each section,…

About 15,000 BC, the bison and other animals roamed the land and cave people, in their spare time, found colorful, chalky rocks with which to play. Over the course of time, they found that the chalky rocks would rub off on the cave walls, thus cave paintings and the pursuit of art was born. This article describes one fourth-grade classroom's…

Presents a laboratory experiment that examines the aggressive behavior of male paradise fish. Students design the experiment, collect data, and analyze and interpret the results. This activity is appropriate for biology, ecology, and animal behavior classes and allows students to be involved in the entire scientific process. (Author/NB)

The Bumblebee Game is an exciting outdoor game, which demonstrates aspects of bumblebee natural history including food chains, food webs and competition for food, predation by crab spiders, parasitism by "Conopidae" ("Diptera") and brood parasitism by cuckoo bees. It has been played successfully with groups of 10-25 people. Although most suitable…

Fragile X syndrome is the most common heritable form of mental retardation caused by loss-of-function mutations in the "FMR1" gene. The "FMR1" gene encodes an RNA-binding protein that associates with translating ribosomes and acts as a negative translational regulator. Recent work in "Drosophila melanogaster" has shown that the fly homolog of…

Many preschoolers know that plants and animals share basic biological properties, but this knowledge does not usually lead them to conclude that plants, like animals, are living things. To resolve this seeming paradox, we hypothesized that preschoolers largely base their judgments of life status on a biological property, capacity for teleological…

Mirror neurons, first described in the rostral part of monkey ventral premotor cortex (area F5), discharge both when the animal performs a goal-directed hand action and when it observes another individual performing the same or a similar action. More recently, in the same area mirror neurons responding to the observation of mouth actions have been…

Three experiments with paired comparisons were conducted to test the noncompensatory character of the recognition heuristic (D. G. Goldstein & G. Gigerenzer, 2002) in judgment and decision making. Recognition and knowledge about the recognized alternative were manipulated. In Experiment 1, participants were presented pairs of animal names where…

Building on the foundation of previous research about battered women's experiences with animal abuse, this study takes a closer look at: (1) the factors associated with battered women's concern for their pets and (2) decision making associated with this concern. Quantitative survey data of in-shelter domestic violence victims as well as…

This paper describes an educational package for use in tertiary level tissue engineering education. Current learning science principles and theory were employed in the design process of these educational tools. Each module started with a challenge statement designed to motivate students and consisted of laboratory exercises centered on the "How…

The relevance of perirhinal cortical cholinergic and glutamatergic neurotransmission for taste recognition memory and learned taste aversion was assessed by microinfusions of muscarinic (scopolamine), NMDA (AP-5), and AMPA (NBQX) receptor antagonists. Infusions of scopolamine, but not AP5 or NBQX, prevented the consolidation of taste recognition…

Rats were trained to search for a food reward hidden under sawdust in the center of a square-shaped enclosure designed to force orientation on the basis of the overall geometry of the environment. They were then tested in a number of enclosures differing in shape and in size (rectangular-, double-side square-, and equilateral triangle-shaped…

Emotionally charged experiences alter memory storage via the activation of hormonal systems. Previously, we have shown that compared with rats trained for a massed spatial learning task in the water maze in warm water (25 degrees C), animals that were trained in cold water (19 degrees C) performed better and showed higher levels of the stress…
