When Professor Joel Levine's team genetically tweaked fruit flies so that they didn't produce certain pheromones, they triggered a sexual tsunami in their University of Toronto Mississauga laboratory.
Staying at home may have given the very first termite youngsters the best opportunity to rule the colony when their parents were killed by their neighbors. This is according to new research supported by the National Science Foundation and published today in the Proceedings of the National Academy of Sciences.
New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture.
Scientists have always been puzzled by the science of pheromones, even with animals. The fact that dogs have a sense of smell we still do not understand. Certain smells attract dogs, and other repell. Yet, there is no way to measure or comprehend which dogs find attractive.
PROVIDENCE, R.I. [Brown University] -- Brown University researchers have discovered that Candida albicans, a human fungal pathogen that causes thrush and other diseases, pursues same-sex mating in addition to conventional opposite-sex mating.
BOSTON, Mass. (July 16, 2009) -- There she is again: the cute girl at the mall. Big eyes. Long legs. She smiles at you. You're about to make your move? but wait! What's she wearing? It's a letterman jacket, one clearly belonging to a hulking football player named "Steve." This girl is taken. Wisely, you move on.
Scientists here have determined that combining bed bugs' own chemical signals with a common insect control agent makes that treatment more effective at killing the bugs.
The researchers found that stirring up the bed bugs by spraying their environment with synthetic versions of their alarm pheromones makes them more likely to walk through agents called desiccant dusts, which kill the bugs by mak
A Queensland University of Technology researcher has filmed hours of prawn "sex tapes" to find out why prawns bred in captivity did not go on to breed well.
A recent discovery unveils the chemical secret that gives old bees the authority to keep young bees home babysitting instead of going out on the town. A hard-to-detect pheromone explains a phenomenon Michigan State University entomologist Zachary Huang published 12 years ago -- that somehow older forager bees exert influence over the younger nurse bees in a hive, keeping them grounded until they are more mature, and thus more ready to handle the demands of buzzing about.
Scientists have found that exposure to male perspiration has marked psychological and physiological effects on women: It can brighten women's moods, reducing tension and increasing relaxation, and also has a direct effect on the release of luteinizing hormone, which affects the length and timing of the menstrual cycle.
For the first time, researchers have eavesdropped on the brains of mice as they go about the normal behaviors of detecting the subtle chemical signals called pheromones from other animals. The researchers have discovered that the animals' pheromone-processing machinery in the brain forms, in essence, a specific "pheromonal image" of another animal. Such an "image" of another animal's sex, identity, social standing and female reproductive status governs a range of mating, fighting, maternal-infant bonding and other behaviors. The scientists said that the specificity they discovered in the neurons that process pheromonal signals is akin to the "face neurons" in the visual areas of primate brains that are specifically triggered by facial features of other animals.
Paper wasps all look the same, right? An animal behaviorist at Cornell University reports that the wasp's black-and-yellow uniform is not uniform at all. One wasp, she has discovered, can recognize another through facial and abdominal markings, all but displacing the scientific dogma that insects carry out identification and communication only by employing chemicals called pheromones. "Their faces are far more beautiful and different than you'd expect," says Elizabeth Tibbetts.
