In search of hair damage using metabolomics?

YesHair fibres are extraordinary materials, not least because they are exquisitely formed by each of the 5 million or so hair follicles on our bodies and have functions that cross from physiology to psychology, but also because they have well known resistance to degradation as seen in hair surviving from archaeological and historical samples [1]. Hair fibres on the head grow at around 1cm each month, together totalling approximately 12km of growth per person per year. Each fibre is incredibly strong for its small diameter; with one fibre typically holding 100g and together a well-formed ponytail [allegedly] has the collective strength to support the weight of a small elephant! Hair – and from here I mean scalp hair – is under constant scrutiny by each of us; whether it be style, split ends, the first few grey hairs or the collection of hairs in the shower that should be firmly attached - leading to the fear that is hair loss

Screen as Skin: The Somatechnics of Touchscreen Music Media

In this article I explore the way mobile music devices with touchscreen technology produce new somatechnical figurations that reshape emotional dynamics of music listening. Using research drawn from a cyberethnography of online users from Reddit.com, I argue that the changing relationships between the human-computer interface result in new affective schemas that expand and reconfigure how it feels to listen to music in a mobile setting. In particular, I focus on skin-on-screen contact in order to suggest that the screen acts as a reflexive surface producing intimate relations for the mobile listener. Touchscreens imply the relationship between skin on skin—the skin of our body (in particular the hands) against the skin of the screen. It follows that mobile touchscreen devices suggest a degree of sensuality—in the coming together of bodies, fluids and other organic materials which ‘stick’ to the touchscreen. Reading the mobile touchscreen player as a somatechnical figuration therefore suggests that the listening experience is developing along with the technologies that mediate music to the body in ways that continue to challenge our understanding of bodily borders and in ways that redefine what it means to feel the music. Therefore, the touchscreen-skin is a critical site of affective relations that dramatically reshape what it means to listening to music in a mobile setting; a private and intimate encounter between the user and their counterpart
