The rights of microbes
Over the last forty years, the circle of organisms thought worthy of inclusion within an ethical framework has expanded markedly, in large part in response to Aldo Leopold’s ‘land ethic’. […]

Impact-shocked rocks – insights into archean and extraterrestrial microbial habitats (and sites for prebiotic chemistry?)
Read more of: Impact-shocked rocks – insights into archean and extraterrestrial microbial habitats (and sites for prebiotic chemistry?)Impact-shocked gneiss shocked to greater than 10 GPa in the Haughton impact structure in the Canadian High Arctic has an approximately 25-times greater pore surface area than unshocked rocks. These […]

Growth in the limpet Nacella concinna from contrasting sites in Antarctica
Read more of: Growth in the limpet Nacella concinna from contrasting sites in AntarcticaAnnual shell growth was determined by mark and recapture in the limpet Nacella concinna (Strebel 1908) at two contrasting sites in Antarctica. At Signy Island, 60degreesS, growth was moderately fast, […]

Is there a Universal Temperature Dependence of metabolism?
Read more of: Is there a Universal Temperature Dependence of metabolism?In a challenging and provocative paper Gillooly et al. (2001) have proposed that the metabolism of all organisms can be described by a single equation, * Q = b0M3/4e−E/kT, where […]

Coupling between substorms and ULF disturbances at polar latitudes
Read more of: Coupling between substorms and ULF disturbances at polar latitudesThe trans-Antarctic search-coil magnetometer network has been used to study a possible coupling between the nighttime substorm activity and the behavior of ULF pulsations in the dayside cusp and nightside […]

Lidar observations of polar mesospheric clouds at Rothera, Antarctica (67.5 degrees S, 68.0 degrees W)
Read more of: Lidar observations of polar mesospheric clouds at Rothera, Antarctica (67.5 degrees S, 68.0 degrees W)Polar mesospheric clouds (PMC) were observed by an Fe Boltzmann temperature lidar at Rothera (67.5degreesS, 68.0degreesW), Antarctica in the austral summer of 2002-2003.The Rothera PMC are much weaker, less frequent, […]

A statistical comparison of SuperDARN spectral width boundaries and DMSP particle precipitation boundaries in the nightside ionosphere
Read more of: A statistical comparison of SuperDARN spectral width boundaries and DMSP particle precipitation boundaries in the nightside ionosphereThe boundary between quasi-dipolar (closed) geomagnetic field lines and those connected to the interplanetary magnetic field (open) is a key diagnostic for the magnetospheric system. This study presents an HF […]

Measuring the dayside reconnection rate during an interval of due northward interplanetary magnetic field
Read more of: Measuring the dayside reconnection rate during an interval of due northward interplanetary magnetic fieldThis study presents, for the first time, detailed spatiotemporal measurements of the reconnection electric field in the Northern Hemisphere ionosphere during an extended interval of northward interplanetary magnetic field. Global […]
