Not (B)interested? Using Persuasive Technology to Promote Sustainable Household Recycling Behavior

In many recycling systems around the world, waste is separated at the source. Their success therefore depends on an active participation of households. However, especially young people have been found to not consistently follow their local recycling schemes. A promising approach to tackle such suboptimal household recycling behavior (HRB) is the use of persuasive technology. While existing studies have highlighted its potential, they also commonly relied on waste container augmentation. To better understand the requirements of augmentation-independent HRB-related persuasive technology, a two-phase study was carried out with young adults in Sweden. First, an online survey (N = 50) was used to establish the target users' recycling-related problems, attitudes and interests. Then, based on the survey results, a mobile phone application was designed and evaluated in an iterative manner. This led to the following design recommendations: (1) easy access to information about optimal household recycling behavior, (2) employment of several motivational strategies, (3) recognition of recycling scheme differences, (4) regard of users as equals and (5) use of a readily accessible technology channel. The technological format of persuasive technology interventions was found to spark the users' curiosity. Within a well-functioning recycling system and along with engaging content, it could encourage repeated use and elicit reflection to help break unsustainable household recycling habits

Import of adenovirus DNA involves the nuclear pore complex receptor CAN/Nup214 and histone H1

Adenovirus type 2 (Ad2) imports its DNA genome through the nuclear pore complex (NPC) of cells in interphase for viral production. Here we identify the NPC-filament protein CAN/Nup214 as a docking site for incoming Ad2 capsids. Binding to CAN is independent of cytosolic factors. Capsids disassemble at NPCs to free their DNA for import. This process requires binding of nuclear histone H1 to the stably docked capsids and involves H1-import factors, restricting this irreversible process to the proximity of the nucleus. Our results provide a molecular mechanism for disassembly of Ad2 and reveal an unexpected function of histone H1 in virus-mediated DNA import
