The extent to which sexual harassment from males can damage relationships between females is revealed in a new study. Led by the Centre for Research in Animal Behaviour at the University of Exeter and published in Proceedings of the Royal Society B, the research uncovers the effect of sexual harassment on the ability of female fish to form social bonds with each other.
Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments.
A Web-based reporting system may help clinicians track surgical complications and detect patterns of adverse events, identifying opportunities to improve the quality of care, according to a new article.
During the summers of 2006 and 2007, an international team of researchers from China and the United States excavated a treasure trove of dinosaur skeletons from Early Cretaceous rocks in the southern part of the Gobi Desert near the ancient Silk Road city of Jiayuguan, Gansu Province, China. Two of their discoveries represent new species of theropod dinosaurs.
Our ability to use objects and tools to perform actions is essential to our daily activities, and it is developed to a level that is unique to our species. In a study performed by a scientific team of the French National Center for Scientific Research (CNRS) and the Paris Descartes University, researchers have found that brain-lesioned patients who have difficulties using familiar objects and tools in their usual context (e.g. cutting paper with scissors) may also be impaired at controlling the movement of an object in the context of simpler movements such as pointing at a target.
Rare plant and animal species are like rare stamps or coins: they are perceived to be inherently more valuable to people, whatever they look like. Researchers Elena Angulo and Franck Courchamp, from Université de Paris-Sud, have found that people are more attracted to species labeled “rare” than those labeled “common” even when they do not know which species are involved.
Researchers from the United States and Canada have found a fossil skeleton of a newly discovered carnivorous animal, Puijila darwini. New research suggests Puijila is a “missing link” in the evolution of the group that today includes seals, sea lions, and the walrus.
An international consortium of scientists has probed further into the human genome than ever before. They have discovered how genes are controlled in mammals, as well as the tiniest genetic element ever found.
