Researchers have uncovered a gene in corals that responds to day/night cycles, which provides some tantalizing clues into how symbiotic corals work together with their plankton partners. Corals are fascinating animals that form the largest biological constructions in the world, sprawling coral reefs that cover less than 0.2 % of the seafloor yet provide habitats for more than 30% of marine life. In shallow waters that don't have abundant food, corals have developed a close relationship with small photosynthetic critters called dinoflagellates.
The phenomenon of "shimmering" in giant honeybees, in which hundreds--or even thousands--of individual honeybees flip their abdomens upwards within a split-second to produce a Mexican Wave-like pattern across the bee nest, has received much interest but both its precise mode of action and its purpose have long remained a mystery.
Nearly every child who receives an antipsychotic medicine is first prescribed one of the second-generation, or "atypical" drugs, such as olanzapine and risperidone. However, there has never been evidence that these drugs are more effective than the older, first-generation medications.
Our brains contain their own navigation system much like satellite navigation ("sat-nav"), with in-built maps, grids and compasses, neuroscientist Dr Hugo Spiers told the BA Festival of Science at the University of Liverpool on September 11.
INRA and CNRS French scientists and a UFZ German scientist found that the worldwide economic value of the pollination service provided by insect pollinators, bees mainly, was â¬153 billion* in 2005 for the main crops that feed the world.
Is it always good to respond maximally when pathogens or disease strike, or should individuals vary their immune response to balance immediate and future costs?
A new species of blind, subterranean, predatory ant discovered in the Amazon rainforest by University of Texas at Austin evolutionary biologist Christian Rabeling is likely a descendant of the very first ants to evolve.
A wireless measuring system, consisting of sensors and transmission units, helps to keep livestock healthier with a minimum use of resources.
