Abstract: The invention provides methods, kits, and related compositions for rapid, low-cost, point of care detection of an organism, such as a virus or bacteria, in a biological or environmental sample using isothermal nucleic acid amplification.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving data identifying contexts; selecting an initial set of questions based at least on the contexts; providing a respective representation of the questions of the initial set, for output; receiving data indicating a selection of a particular representation associated with a particular question of the initial set of questions; selecting a set of answers associated with the particular question; providing a respective representation of the answers of the set that are associated with the particular question, for output; receiving data indicating a selection of a particular representation associated with a particular answer of the set that are associated with the particular question; determining that an additional set of other questions is associated with the particular answer; and in response to the determining, providing a respective representation of the other questions of the additional set, for output.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing data deliver for data constrained user devices. In one aspect, a method includes the actions of receiving, from a user device, requests for resources. For each of the requests, determining whether the user device is currently subject to a data constraint for receiving data responsive to the request. For each request for which the user device is determined to be subject to the data constraint, provide data that causes the user device to display a prompt to choose whether a resource responsive to the request is to be provided in the unrestricted data form or a restricted data form. A resource can be provided in an unrestricted data form has a first data size and provided in a restricted data form has a second data size that is less than the first data size.

Abstract: A mobile messaging platform for communicating among a plurality of wireless devices comprises at least one gateway configured to communicate with mobile devices and to forward communication over a network. A server containing content is coupled over the network to the gateway, and adapted to receive calls from at least one mobile device to forward content to one or more parties. In one aspect, the mobile devices include cellular telephones, and the content includes rich media. In another aspect, the content includes ring tones, wall paper, mobile games, phone applications and more complex programs and games. Advantages of the invention include the ability to communicate rich content to other users including ring tones, wall paper, mobile games, phone applications and even more complex programs, games and other content.
