Bill S. Hansson – författare

Lukter utgör en så självklar del av livet att de ofta förbises. Men de spelar en mer avgörande roll än vad vi kan tro – för bland annat minne, parbildning och överlevnad hos både människor och djur. Även växter har en sorts luktsinne som de använder för att motta doftmeddelanden och varningssignaler.

I den här boken tecknas historien om lukternas förbisedda värld. Det är en berättelse om vad lukter är, om varför naturens dofter uppfattades så annorlunda av våra förfäder, om hur djur kommunicerar, lockar och bedrar varandra med dofter – och om hur den senaste luktteknologin kan komma att förändra vårt doftsinne i grunden.

Smell is arguably the least understood sense, yet it has always been a vital component of the human experience, and that of all living creatures.

Smell has been used by plants and animals for millions of years to warn, to attract, to identify, to navigate and even to mislead. Smelling to Survive explains some of these fascinating processes and explores how the past would have smelt quite different to our ancestors, and how future technologies will further change the world of scents.

Along the way, leading scientist Bill S. Hansson recounts amazing stories from the world of olfactory research: from the tobacco plant that excretes an alarm odour, to mosquitos that cherish the smell of sweaty feet, to lilies that imitate the fragrance of a dead horse. Hansson explains why scientists are interested in the smell that surrounds teenage males, and how climate change affects the smell of our environment. He describes research trips to Christmas Island, where crabs with particularly keen noses crack coconuts on the beach, and outlines studies that reveal how penguins recognize their partner by their scent.

Born in Sweden, the neuroethologist Bill S. Hansson served as Vice President of the Max Planck Society and is currently Director of the Max Planck Institute for Chemical Ecology in Jena, Germany, and an honorary professor at Friedrich Schiller University. His research centres on the question of how plants and insects communicate through scent.
