Separate species that live in radically different environments don't necessarily also have different ecological niches. This is the finding of a study investigating the accuracy of current statistical tests that use models of geographic distributions to infer changes in environmental requirements. In a new study published in the journal Systematic Biology, a model simulating the distributions of two imaginary species with identical environmental requirements, or ecological niches, was...

Scientists have determined that a new instrument known as PIB-PET is effective in detecting deposits of amyloid-beta protein plaques in the brains of living people, and that these deposits are predictive of who will develop Alzheimer's disease. The finding, the result of a survey of more than 100 studies involving the instrument, including those by the scientists, confirms the sensitivity of the tool, not yet commercially available. In clinical practice, amyloid deposits are detected only on...

Only in recent years have scientists figured out that the secretive Amazonian manatee migrates from shallow to deeper waters. The manatees make this dangerous journey to avoid exposure to predatory attack during the low-water season. Scientists speculate that these peaceful creatures may be at an even greater danger than thought, as migration and low-water levels make them easily accessible to hunters. Caimans, jaguars, and humans are all threats to the manatee. Even though hunting manatees...
