# gst: more light on 'zombie' phenomena

<< Various parasite-host interactions that involve adaptive manipulation of host behavior display time-of-day synchronization of certain events. One example is the manipulated biting behavior observed in Carpenter ants infected with Ophiocordyceps unilateralis sensu lato >>

AA << hypothesized that biological clocks play an important role in this and other parasite-host interactions >>

# gst: the intriguing dynamics of a crack

<< Cracks develop intricate patterns on the surfaces that they create >>

<< Although fracture mechanics predict that slow crack fronts should be straight and form mirror-like surfaces, facet-forming fronts propagate simultaneously within different planes separated by steps >>

# game: Kel'Thuzad e' il Lich responsabile

<< Kel'Thuzad e' il Lich responsabile di aver diffuso la piaga dei non-morti nel regno di Lordaeron ma e' probabilmente piu' conosciuto dai fan per essere il signore della necropoli di Naxxramas e dunque il boss finale dell'omonimo dungeon. Apparsa inizialmente in World of Warcraft, Naxxramas fu poi riutilizzata nella seconda espansione, Wrath of the Lich King, poiche' quasi nessuno era riuscito a raggiungere il livello necessario per provare il raid la prima volta >>

# brain: actually they have heads that shrink ...

AA << followed the intra-individual change in skull size and body mass throughout the full cycle in wild recaptured shrews (Sorex araneus) >>

Using X-ray images [AA] << showed that individuals decreased the size of their braincases in anticipation of winter by an average of 15.3%. Braincases then partially regrew in spring by 9.3%. Body mass decreased by 17.6% and then dramatically increased by 83.4% in spring >>
