Intro post! My lab at Loyola University Chicago studies genetic causes of #cardiomyopathy (#HCM, #DCM) and #AFib with a focus on #myofilament and #sarcomere function.
I had very little time to enjoy having gotten this particular boulder to the top of the hill this morning.

Oak Park resident Scott Sakiyama reports feds pointed weapons at him across from an elementary school today. They then arrested him and took him to Broadview. While in custody, he saw agents texting in a group chat called "Chiraq Team 2."

A friendly reminder that the NIH Public Access Policy IS NOT “you must publish open access” but rather “you must ensure your copy of your paper is deposited into PubMed Central.”

Yes, it is very confusing. Yes, you should be able to do that deposit yourself without paying anything to a journal.
