Current Biology celebrates its 25th birthday with a special issue on January 5, 2015 on the biology of fun (and the fun of biology). In a collection of essays and review articles, the journal presents what we know about playfulness in dogs, dolphins, frogs, and octopuses. It provides insights on whether birds can have fun and how experiences in infancy affect a person's unique sense of humor. "Fun is obviously--almost by definition--pleasurable, rewarding, but in a way that is distinct from the pleasures of satisfying basic needs, such as the drives to reduce thirst or hunger or to reproduce," says Current Biology Editor Geoffrey North. "The articles in this special issue consider examples of what appear to be fun and play in a broad range of animal species and the insights that can be gained into how the behaviors might contribute to evolutionary fitness." How do we get our sense of humor? Psychologists Vasu Reddy and Gina Mireault, of the University of Portsmouth and Johnson State College respectively, offer a comprehensive overview of how, in infancy, reactions to absurd behavior like pulling hair or blowing raspberries, as well as teasing others, offer a window into how aware young children are … Continue reading →

New research published in the Journal of Leukocyte Biology suggests that T cells promote inflammation in the fat tissue of diet-induced obese mice, a known risk factor for insulin resistance and type 2 diabetes New research in mice suggests that an unusual type of immune cell called " T cells" may be a new drug and research target for treating or preventing type 2 diabetes caused by obesity. The research report, appearing in the January 2015 issue of the Journal of Leukocyte Biology, suggests that T cells are necessary for obesity-induced accumulation of macrophages, which are associated with promoting inflammation in fat tissue. This inflammation, which is induced during obesity, is known to be a risk factor for insulin resistance and type 2 diabetes, but its underlying causes have not been clear. "Results showed that T cells contribute to systemic insulin resistance in obese mice, which opens up new avenues for studies in obese humans," said Pooja Mehta, Ph.D., a researcher involved in the work from the Department of Pathology and Immunology at Baylor College of Medicine in Houston, Texas. "This study also provides new information about the complex interplay of immune cells, in the fat tissue, during obesity." To … Continue reading →

Contact Information Available for logged-in reporters only Newswise Education for the blind has lagged because science classrooms predominantly rely on visually-based materials. However, innovative new toolboxes on evolutionary biology, set to be released next year, may revolutionize science education for more than 60,000 blind K-12 students, allowing them to collect data through their fingertips and incorporate their findings into a scientific framework. This work is important because it helps teach students to think like scientists, aiming to instill in these students enthusiasm for lifelong learning, explains Dr. Colleen Farmer of the University of Utah, the leader of the project. Farmer and her colleagues have been developing evolutionary toolboxes for blind and visually-impaired K-12 students in collaboration with the Utah Museum of Natural History and the National Federation of the Blind. The toolboxes contain audio and Braille lesson plans, three-dimensional models, tactile games, graphics, and maps, all incorporated into comprehensive lesson plans that address key concepts in evolutionary biology, anatomy, and conservation biology. This initiative, funded by the National Science Foundation, has already produced two prototype toolboxes. The lessons in the toolbox are designed to give students a hands-on, tactile learning experience and to engage them in the scientific process through … Continue reading →
