Abstract: This invention relates to a roof tile comprising a top surface, a bottom surface, a pair of side edges and a pair of end edges. The roof tile comprises an overlapping portion for overlapping an adjacent roof tile and an underlapping portion for underlapping another adjacent roof tile. The overlapping portion comprises a solar panel forming the top surface and there are provided electrical connectors in communication with the solar panel for connection of the solar panel to a household power supply system. Ideally, a plurality of the roof tiles may be connected together to provide more electricity and each roof tile is provided with connectors for connection of the roof tile to other roof tiles. In this way, the solar panel will be integrated seamlessly into the roof, will not be proud of the roof and will not require a frame for mounting on the roof.

Abstract: An apparatus includes a catheter, and an electrode and methods of delivering molecules to eukaryotic cells using such an apparatus. The catheter defines a fluidic channel and has a distal opening. The electrode is within the fluidic channel and is spaced a distance from the distal opening of the catheter. The catheter is arranged to prevent direct contact between any electrode of the apparatus and tissue. Related apparatus, systems, techniques and articles are also described.

Abstract: Delivering a payload across a plasma membrane of a cell includes providing a population of cells and contacting the population of cells with a volume of an aqueous solution. The aqueous solution includes the payload and alcohol content greater than 5 percent concentration. The volume of the aqueous solution may be a function of exposed surface area of the population of cells, or may be a function of a number of cells in the population of cells. Related compositions, apparatus, systems, techniques, and articles are also described.

Abstract: An apparatus for use with a barrier having an overhanging ledge to limit movement by a person on the ledge. The apparatus has an upright member that is positioned next to the barrier, a base member at a lower end of the upright member that is positioned on a surface adjacent the barrier and opposite the ledge, a mechanism for engaging the barrier to hold the apparatus in place and a plurality of limiting members that extend across the ledge to prevent movement past the apparatus. In one configuration, each of the limiting members extend through openings in a railing above the barrier. The engaging mechanism defines a gap that receives the barrier to hold the apparatus to the barrier. The base member can have a footplate on which weight can be placed. A system has a pair of apparatuses that define an area in which movement is allowed.
