DO CHROMOSOMES WORK THROUGH STRESS?
A paper in the August 24 issue of Proceedings of the National Academy of Sciences, U.S.A., from the Kleckner lab provides a new theory of chromosome function that…
MATHEMATICAL MODELS OF ROBUSTNESS IN DEVELOPMENT
Biological systems are robust; they function reliably despite disruptions. Internal fluctuations occurring on a microscopic scale or changes in external conditions, such as temperature, pose challenges to system…
FINDING A PRESYNAPTIC ORGANIZER THAT MAKES THE BRAIN FUNCTIONAL
Neurons analyze and transmit information in the brain. Information is transferred from one neuron to another through the functional contact sites called synapses. When a neuron is activated,…
NEW LIGHT ON CROSSOVER DIFFERENTIATION
G. Valentin Boerner Nancy Kleckner Neil Hunter Meiosis is the modified cellular program by which a diploid cell produces haploid gametes as required for sexual reproduction. A key…
