In this issue we are introducing two new manuscript formats, Model Profile and Technology Feature. These are in addition to the new format section we started in the last issue, Therapeutic Brief, which has attracted much attention. Please see the Therapeutic Brief by Wang et al., in this issue on the potential of XPO1 inhibitor in relapsed hematological malignancies.

The new Model Profile format is designed to provide a venue for publishing brief reports on novel aspects of models for aging or age-related diseases including cancer. The focus is not just on animal models but also on invertebrates, cell lines, and statistical models including algorithms. Please see the Model Profile manuscript in this issue by Dou et al., describing a mouse model of sleep deprived neuropathology.

The Technology Feature is designed to provide a format for publishing brief reports on novel technology issues supporting experimental and clinical research in pathobiology of aging and age-related diseases. Again, this is will be an open venue for gerontology and geriatric research and clinical investigations. Please see the Technology Feature in this issue by Lee et al., describing the use of QuPath as a digital imaging tool for geropathology.  

These formats are meant to be regularly occurring sections with each issue and we are excited to provide additional opportunities for increasing the depth of our journal. Each new format will generally consist of two to five pages, not counting references, with a limited number of figures and tables. Organization of subsections will at the discretion of the authors, but the main message must be focused and concise. We welcome submissions as well as inquiries on ideas for manuscripts for these new formats or our other more traditional manuscript formats.
