Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006.We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family.Instead, we place it in the new family Bryopompi
Backgroud: The growing emergence of antibiotic-resistant pathogens including the most dangerous superbugs requires quick discovery of novel antibiotics/biopreservatives for human health and food safety.Bacteriocins, a subgroup of antimicrobial peptides, have been considered as promising alternatives to antibiotics.Abundant novel bacteriocins are st
Radar altimetry in the context of sea ice has mostly been exploited to retrieve basin-scale information about sea ice thickness.In this paper, we investigate the sensitivity of altimetric waveforms to small-scale changes (a few hundred meters to about 10 km) of the sea ice surface.Near-coincidental synthetic aperture radar (SAR) imagery and CryoSat
