Vibrational Raman spectroscopic study of scytonemin, the UV-protective cyanobacterial pigment
Read more of: Vibrational Raman spectroscopic study of scytonemin, the UV-protective cyanobacterial pigmentThe Raman spectrum of the photoprotective pigmentscytonemin found in cyanobacterial sheaths has been obtained for the first time. Its skeletal structure is extensively conjugated and unique in nature. Detailed molecular […]

Profiling cryopreservation protocols for Ribes ciliatum using differential scanning calorimetry
Read more of: Profiling cryopreservation protocols for Ribes ciliatum using differential scanning calorimetryDSC analysis was performed at three points in the cryopreservation process on encapsulated-dehydrated meristems of Ribes ciliatum. Meristems were excised from shoots pre-treated with either sucrose or glucose, encapsulated in […]

A novel miniature confocal microscope/Raman spectrometer system for biomolecular analysis on future Mars missions after Antarctic trials
Read more of: A novel miniature confocal microscope/Raman spectrometer system for biomolecular analysis on future Mars missions after Antarctic trialsBiomolecules, such as the productive and protective pigments of photosynthetic organisms, are good biomarkers in extreme Antarctic deserts as analogues of early Mars. Laser Raman technology at long wavelengths which […]

Molecular evidence for genetic mixing of Arctic and Antarctic subpolar populations of planktonic foraminifers
Read more of: Molecular evidence for genetic mixing of Arctic and Antarctic subpolar populations of planktonic foraminifersBipolarity, the presence of a species in the high latitudes separated by a gap in distribution across the tropics, is a well-known pattern of global species distribution. But the question […]

Cephalopod diet of the southern elephant seal, Mirounga leonina, at King George Island, South Shetland Islands
Read more of: Cephalopod diet of the southern elephant seal, Mirounga leonina, at King George Island, South Shetland IslandsIn the summer of 1995/96, 25 southern elephant seals, Mirounga leonina, were stomach lavaged at Stranger Point, King George Island, South Shetland Islands. Cephalopod remains were present in 72% of […]
