International research team unveils new data describing the interaction between genetic and epigenetic variation in Arabidopsis thaliana. HHMI scientists have profiled key features of the genetic material inside three types of brain cells and found vast differences in the patterns of chemical modifications that affect how the genes in each type of neuron are regulated. Eleven HHMI scientists are elected to the American Academy of Arts and Sciences. New research reveals details of changing DNA methylation patterns as the brain matures. A discovery of how ethylene triggers changes in gene activity could lead to new ways to stop or slow ripening. Fifteen scientists working in the plant sciences gain flexible support from HHMI and the Gordon and Betty Moore Foundation to move their research in creative new directions.
