The 42nd International Sun Valley Workshop on Musculoskeletal Biology will be held 5-8 August in Sun Valley, Idaho. The Sun Valley Workshops have a tradition of providing multidisciplinary training to younger scientists, and today continues to provide a unique opportunity to connect senior investigators with young investigators. The overall objective of this four day Workshop is to improve understanding across the many disciplines that study skeletal biology and the prevention/treatment of musculoskeletal disease. The Workshops are unusual in that discussion time equals or exceeds time allotted for formal presentation. We hope you can join us this year in Sun Valley.
