Open system crystal fractionation and incompatible element variation in basalts
Read more of: Open system crystal fractionation and incompatible element variation in basaltsO’HARA1 has recently proposed an open-system model for the fractional crystallisation of magmas involving continual replenishment of the magma chamber and only partial extraction of the fractionated liquid at each […]

Strontium isotope evidence for mantle events in the continental lithosphere
Read more of: Strontium isotope evidence for mantle events in the continental lithosphereFollowing current interpretation of isotope data from oceanic basalts, the case for inheritance of Rb/Sr and 87Sr/86Sr ratios in continental igneous rocks from long-lived heterogeneities in the mantle is reviewed, […]

The cryopreservation of Chlorella
Read more of: The cryopreservation of ChlorellaFollowing a shift from autotrophic to heterotrophic nutrition, cells of Chlorella protothecoides become sensitive to the stresses of freezing and thawing. The injury then observed at slow rates of cooling […]

Computationally Predicted Gene Regulatory Networks in Molluscan Biomineralisation Identify Extracellular Matrix Production and Ion Transportation Pathways
Read more of: Computationally Predicted Gene Regulatory Networks in Molluscan Biomineralisation Identify Extracellular Matrix Production and Ion Transportation PathwaysMotivation The molecular processes regulating molluscan shell production remain relatively uncharacterised, despite the clear evolutionary and societal importance of biomineralisation. Results Here we built the first computationally predicted gene regulatory […]

Establishment and eradication of an alien plant species in Antarctica: Poa annua at Signy Island
Read more of: Establishment and eradication of an alien plant species in Antarctica: Poa annua at Signy IslandInvasive alien species are among the most significant conservation threats for Antarctica, and the South Orkney Islands are highly exposed to this threat because of their location and intensity of […]
