A beverage container comprising a stem having an upper and a lower end, a cup having an upper opening and a lower bowl portion, and a base having a tapered upper end with a diameter that widens evenly along its length towards a lower end until the diameter is at least equal to a diameter of the upper opening of the cup. The upper end of the stem is attached to the cup at a point centered on the bowl portion of the cup. The upper end of the base is removably attached at to the lower end of the stem, the lower end of the base being capable of securely covering the upper opening when not attached to the stem.

Provided herein are high-input detector modules and multi-input biological classifier circuits and systems that integrate sophisticated sensing, information processing, and actuation in living cells and permit new directions in basic biology, biotechnology and medicine. The multi-input biological classifier circuits described herein comprise synthetic, scaleable transcriptional/post-transcriptional regulatory circuits that are designed to interrogate the status of a cell by simultaneously sensing expression levels of multiple endogenous inputs, such as microRNAs. The classifier circuits then compute whether to trigger a desired output or response if the expression levels match a pre-determined profile of interest.

In its various embodiments, the invention provides, first, a composition comprising a vector for transfecting a cell. The vector comprises a first nucleic acid encoding an antisense agent having thereon an RNA interference target for a transcript of a gene endogenous to the cell. The vector further comprises a second nucleic acid that encodes a cell-killing agent. The second nucleic acid further comprises a sequence of nucleotides transcribable into a non-coding region of a transcript of the second nucleic acid, such that the non-coding region becomes an RNA interference target for the antisense agent. In the transfected cell, the vector operates to interfere with the expression of the cell-killing agent unless and until the vector senses certain endogenous gene signals, whereupon it releases the cell-killing agent. Second, the invention provides a method of treating a disease in a patient by killing cells responsible for the disease, the method comprising administering the vector to the patient until the disease, or a symptom thereof, is ameliorated.

The present invention provides compositions and methods for programming mammalian cells to perform desired functions. In particular, the present invention provides compositions and methods for programming stem cells to differentiate into a desired cell type. A quorum sensing systems that regulates the expression of cell fate regulators is introduced into mammalian host cells, such as stem cells. The quorum sensing systems generally comprises vectors that express the components of a bacterial quorum sensing pathway, including proteins which catalyze the synthesis of an autoinducer and a gene encoding a regulatory partner of the autoinducer, and vectors in which genes encoding cell fate regulators are operably linked to a promoter induced by the autoinducer/regulatory partner complex. The system can also comprise vectors in which genes encoding additional cell fate regulators are operably linked to a promoter that is induced by a factor synthesized in response to a first stage of differentiation, so that a second stage of differentiation is triggered.
