• Although there is a worldwide surge of interest in conservation, many justifications rest on shaky or ephemeral grounds. • Arguments for conservation of biodiversity often include strong ethical or aesthetic components which are superficially attractive but depend on potentially changeable social circumstances. • Economic justifications based on undiscovered potential are susceptible to chang...

We prove Iqbal’s conjecture on the relationship between the free energy of closed string theory in local toric geometry and the Wess-ZuminoWitten model. This is achieved by first reformulating the calculations of the free energy by localization techniques in terms of suitable Feynman rule, then exploiting a realization of the Feynman rule by free bosons. We also use a formula of Hodge integrals...

This study investigated the roles of endotoxemia and heat-induced tissue damage in the pathology of heat stroke. In groups of eight, male Wistar rats were treated with heat exposure only (HE), or heat exposure with turpentine (T+HE), dexamethasone (D+HE), and turpentine and dexamethasone combined (TD+HE). The rats remained sedated for 2 h after receiving the respective treatments, followed by h...

Robert Insall was born in London in 1965, into a family of architects, musicians and historians. To their great surprise, he was obviously scientifically inclined from an early age. He did a B.A. at Cambridge University, then stuck around in Cambridge for a Ph.D., where he got interested in Dictyostelium, followed by a postdoc in Johns Hopkins, where he got interested in chemotaxis and cell mov...
