Scientists prove how genetics change behavior by studying worms’ foraging strategies

Scientists prove how genetics change behavior by studying worms’ foraging strategiesLike all animals, C. elegans worms pay attention to their peers and can adjust their behavior in response to competition. Neuroscientists have discovered a genetic component of this social phenomenon, providing concrete biological evidence for game theory. More »

Researchers develop gene-filtering tool to identify disease-causing mutations

Genes that are frequently mutated in the general population are unlikely to cause disease, because variations of these genes are often found in healthy people. A new tool from researchers at Rockefeller uses this concept to help scientists identify the mutations in genes that matter. More »

Jean-Laurent Casanova to receive 2014 Robert Koch Award

Jean-Laurent Casanova to receive 2014 Robert Koch Award Casanova is honored for his work on host genes and their products in infectious diseases. His lab is interested in why some children develop severe infectious diseases after coming into contact with certain pathogens, while most other children do not. More »

Genetically identical ants help unlock the secrets of larval fate

Rockefeller researchers are developing a species of small raider ants as a model organism in order to ask questions about the relationships between genes, social behavior and evolution. One such question: How does the interaction between a larvae’s interaction with its caretaker sway the fate of the young animal? More »

Biostatistics approach to genetics yields new clues to roots of autism

Researchers have developed a statistical method for genetic screens that improves the classic genome-wide association screen, and, applying to autism, have uncovered genes related to the disorder that had not been suggested in previous analyses. The scientists offer evidence that beginning treatment in infants at the first symptoms could change the course of the disease, possibly preventing the permanent “pruning” of neurons, which occurs during the first two years of life, from cementing autistic symptoms in place.
