New research published today in the journal Nature Communications represents a potentially fundamental shift in our understanding of how nerve cells in the brain generate the energy needed to function. The study shows neurons are more independent than previously believed and this research has implications for a range of neurological disorders. 

EPFL scientists discover that certain cell structures, the centrioles, could act as information carriers throughout cell generations. The discovery raises the possibility that transmission of biological information could involve more than just genes. Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a...

Members of our species Homo sapiens belonging to the Protoaurignacian culture may have been the ultimate cause for the demise of Neandertals, according to new research. Researchers from the University of Bologna, Italy, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, analysed two deciduous teeth from the prehistoric sites of Grotta di Fumane and Riparo Bombrini in Northern Italy. The state-of-the-art methods...

New research highlights how nerves – whether harmed by disease or traumatic injury – start to die, a discovery that unveils novel targets for developing drugs to slow or halt peripheral neuropathies and devastating neurodegenerative disorders such as Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis (ALS).

Incidence of pertussis (whooping cough) has increased over the last ten years in the United States, with 2012 seeing the highest number of cases since 1955. A new population dynamic model is described in a study in the journal PLOS Computational Biology in an attempt to explain this phenomenon. The results of the study suggest that the upsurge is mainly due to lower efficacy and protection duration of the currently used acellular pertussis...
