Animals navigate and orient themselves to survive -- to find food and shelter or avoid predators, for example. Research conducted by Dr. Nachum Ulanovsky and research student Michael Yartsev of the Weizmann Institute's Neurobiology Department, published today inScience, reveals for the first time how three-dimensional, volumetric, space is perceived in mammalian brains. The research was conducted

Seeds of the model cereal plant Brachypodium distachyon are now available at the RIKEN BioResource Center (BRC) in Japan, the second bioresource facility to provide seeds of this important model plant to the international scientific community. Brachypodium distachyon belongs to the Poaceae family of monocot plants, which comprises temperate grasses and cereals and constitutes one of the most econo

Scientists at Queen Mary, University of London and the Zoological Society of London (ZSL), have discovered why bees copy each other when looking for nectar -- and the answer is remarkably simple. Despite their tiny brains, bees are smart enough to pick out the most attractive flowers by watching other bees and learning from their behaviour. By using simple logic, they see which coloured flowers ar

Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis. Carotenoids, the same pigments which give orange color to carrots and red to tomatoes, are often found together in plants with chlorophyl

New research has uncovered a mechanism that regulates the reproduction of plants, providing a possible tool for engineering higher yielding crops. In a study published today in Science, researchers from Monash University and collaborators in Japan and the US, identified for the first time a particular gene that regulates the transition between stages of the life cycle in land plants. Professor Joh

Results of the PREDIMED study, aimed at assessing the efficacy of the Mediterranean diet in the primary prevention of cardiovascular diseases, have been published inThe New England Journal of Medicine. They show that the Mediterranean diet supplemented with extra-virgin olive oil or tree nuts reduces by 30 percent the risk of suffering a cardiovascular death, a myocardial infarction or a stroke. T

For decades, archaeologists have struggled with understanding the emergence of a distinct South American civilization during the Late Archaic period (3000-1800 B.C.) in Peru. One of the persistent questions has been the role of agriculture and particularly corn (maize) in the evolution of complex, centralized societies. Up until now, the prevailing theory was that marine resources, not agriculture

Can existing ecological communities persist intact as temperatures rise? This is a question of increasing relevance in the field of climate change and is the focus of a new study to be published in the journal Proceedings of the Royal Society of London on 20 February. The study suggests that the answer to this question may have as much to do with the biological interactions that shape communities

Scientists have long puzzled over why "bad" bacteria such as E. coli can thrive in the guts of those with inflammatory bowel disease (IBD), causing serious diarrhea. Now UC Davis researchers have discovered the answer -- one that may be the first step toward finding new and better treatments for IBD. The researchers discovered a biological mechanism by which harmful bacteria grow, edge out benefic
