Researchers discover how Rift Valley fever virus enters cells

Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hundreds of human cases and dozens of deaths. Rift Valley fever, for which there is no specific treatment, has been …

Learning skills of mice help researchers pinpoint brain areas where acquired knowledge is stored

Learning skills of mice help researchers pinpoint brain areas where acquired knowledge is stored

Mice can become experts in sorting images by subtle differences. Part of the acquired knowledge is stored in early visual areas of the brain. Credit: MPI of Neurobiology/ Kuhl Is it a Rembrandt or a Vermeer? For lay people, it is often challenging to distinguish paintings by these two old masters. For the trained eye …

Researchers provide a framework to study precision nutrigeroscience

Researchers provide a framework to study precision nutrigeroscience

A framework for precision nutrigeroscience based on optimizing diet/pharmacology based interventions to optimize health and longevity to accommodate factors that lead to individual variation. We propose the concept of precision nutrigeroscience, the study of which will aim to utilize nutrient interventions and compounds that influence nutrient signaling pathways to optimize lifespan, healthspan and tissue-specific decline. …
