The quote of the week comes from Louis Pasteur:
Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.
Now the weekly cell and molecular biology metablogging:
Gene Expression (classic):
Eye on DNA:
And some ScienceDaily picks below the fold:
In search of the biological significance of modular strutures in protein networks:
Refuting previous studies, the authors show by computer simulation that modular structures can arise during network growth via a simple model of gene duplication, without a natural selection preference for modularity.
Fluorescent video microscopy reveals the dynamic behavior of a protein found in focal adhesions, cell-surface regions rich with receptors for growth factors and points of attachment with the outside world.
The discovery of how some abnormal cells can avoid a biochemical program of self-destruction by increasing their energy level and repairing the damage, is giving investigators insights into a key strategy cancer cells use to survive and thrive.
