IPod Nano had the same price point as the 5th generation device. A firmware update (version 1.1) for the Nano was released on February 28, 2011. The update added the ability to change songs or pause with a double click of the sleep/wake button. It also added the ability to turn the device off by holding the sleep/wake button. The user interface was also enhanced. On October 4, 2011, the iPod Nano 1.2 update was unveiled at the Apple "Let's Talk iPhone" event at the Town Hall, 4 Infinite Loop. This update added the option to increase or decrease the size of
JUNQ and IPOD and processing of different kinds of misfolded proteins (e.g. ubiquitinated vs. non-ubiquitinated proteins). Segregation of toxic protein aggregates into JUNQ and IPOD inclusion bodies is a means by which mammalian cells can be rejuvenated through asymmetric division. Thus, the discovery of JUNQ and IPOD provided a new striking perspective of how cells manage misfolded aggregated proteins and gave convincing proof that protein aggregation is a non-random, well regulated and controlled cellular process. Furthermore, the discovery of JUNQ and IPOD suggested that in addition to temporal quality control (i.e. time dependent administration of damaged proteins) cells exploit homeostasis spatially: If degradation
