Abstract: Embodiments provide notes application features including notes page sharing and notification features, but the embodiments are not so limited. In an embodiment, a computer-based method can be configured to provide a communication to one or more designated recipients, wherein the communication includes one of a view link to a shared page or an editable shared notes page or link thereto. A system of an embodiment includes a server computer configured in part to process notes page sharing requests as part of creating view links to shared notes pages and/or providing users with a means to collaboratively edit a shared notes page. A user interface of an embodiment is configured to share notes pages including displaying notification information regarding other user shared notes page views and/or edits. Other embodiments are included.

Abstract: Methods and compositions for using magnetosomes as cellular contrast agents and markers for magnetic resonance imaging are provided. Certain methods involve synthesizing magnetosomes in a cell as directed by a nucleotide construct comprising an exogenous polynucleotide sequence, wherein the magnetosome serves as a contrast agent or marker for magnetic resonance imaging. Methods of synthesizing and isolating magnetosomes for introduction into immune-matched cells within a tissue or subject for use as a contrast agent or marker for magnetic resonance imaging are also provided. Also provided are methods for stably transfecting cells to express a polypeptide that drives or modulates magnetosome production in the cell, cells produced by such methods and methods for their isolation, transgenic animals comprising at least one eukaryotic cell produced by such methods, and vectors and delivery systems for the transfection of such cells.

Abstract: Embodiments of magnetic resonance eye tracking systems and methods are disclosed. One embodiment, among others, comprises a method that receives magnetic resonance based data and determines direction of a subject's gaze based on the data.
