Another piece on the debacle by the American Diabetes Association (ADA). It includes a quote, that the ADA “effectively disregarded my First Amendment rights.” We need to fight for the right to speak freely, in all public forums, including scientific meetings! www.the-scientist.com/police-remov...

Police Removed Prominent Scientists from the ADA Meeting. Researchers Respond | The Scientist
The organizers of the American Diabetes Association meeting had a group of researchers removed from the event for sharing an editorial about negative impacts of policy changes to research funding.

How to write a grant? 1. The application is for the reviewer, not you, the applicant. 2. Communicate in stories. 3. Make your story cohesive—leave no puzzling gaps. 4. Make your story resonate to keep the reviewer reading. 5. Accept chance and noise in peer-review. www.pnas.org/doi/epub/10....
