Replicative aging of Saccharomyces cerevisiae is an established model system for eukaryotic cellular aging.A limitation in yeast lifespan studies has been the difficulty of separating old cells from young cells in large quantities.We engineered a new platform, the Miniature-chemostat Aging Device (MAD), that enables purification of aged cells at su
Flagellar synchronization through direct hydrodynamic interactions
Flows generated by ensembles of flagella are crucial to development, motility and sensing, but the mechanisms behind this striking coordination remain unclear.We Fridge Door Hinge Cover present novel experiments in which two micropipette-held somatic cells of Volvox carteri, with distinct intrinsic beating frequencies, are studied by high-speed ima

Effect of Major Diseases on Productivity of a Large Dairy Farm in a Temperate Zone in Japan
The objective of the present study was to investigate the associations between major diseases (clinical mastitis, peracute mastitis, metabolic disorders, peripartum disorders) and four parameters related to productivity (305-day milk yield, number of days open, culling rate, death rate) on a large dairy farm in a temperate zone with approximately 2
