Abstract: A method of controlling the flow of an aqueous fluid in a microfluidic device, which makes use of a fluid gate comprising a UCST (upper critical solubility temperature) polymer and which allows fluid to flow by raising the temperature of the fluid gate above the USCT. Also provided is a device incorporating such a fluid gate and the use of such a device to detect an analyte in an aqueous fluid sample.

Abstract: A board game for at least two players comprises a plurality of boards each board having a plurality of recesses located at the perimeter of the board, a plurality of counters each counter of a size suitable to be located within a recess of the board wherein the boards are arranged to be mounted one on top of another, the largest board being placed at the bottom and the arrangement of the boards being such that it forms a tower of boards, each board, except for the largest board, being mounted within the perimeter of the top surface of the board beneath it, the winner of the game being the first player to position a pre agreed number of counters of their own in a row horizontally, vertically or diagonally across any of the boards.
