Just received this from NSF and thought it might be of interest to some:
The Directorate for Biological Sciences (BIO) of the National Science Foundation (NSF) has initiated new procedures for the submission and review of regular research proposals to the core programs within the Division of Molecular and Cellular Biosciences (MCB), Division of Environmental Biology (DEB), and Division of Integrative Organismal Systems (IOS). The changes for MCB were previously announced in a new solicitation (NSF-11-545).
Effective immediately, DEB and IOS will both operate on a single annual cycle of preliminary and full proposals. The initial deadlines for preliminary proposals will be in January, 2012 and the initial deadline for invited full proposals will be in August, 2012. New Solicitations NSF 11-573 (for DEB) and NSF 11-572 (for IOS) provide further details. Also see the Dear Colleague Letter NSF 11-078 and Frequently Asked Questions NSF 11-079 for additional information.
Both DEB and IOS will be hosting webinars to provide further information, please see the Division websites, (DEB) and (IOS), for details and contact information if you have questions or concerns.
