Article Synopsis
- - The introduction of the non-native winter crane fly, Trichocera maculipennis, in maritime Antarctica may threaten the unique local ecosystem, which is vulnerable to foreign species.
- - Researchers conducted tests using advanced methods to determine if T. maculipennis could mechanically transmit various viruses, and identified several human and plant virus genomic fragments in samples collected from the fly.
- - Although the study found low amounts of human adenovirus and retrovirus in the fly samples, which were non-viable, it highlights the need for ongoing research into the impacts of non-native species on Antarctic ecosystems.
Article Synopsis
- The study examined marine litter on the beaches of Punta Arenas, Chile, during the COVID-19 pandemic, identifying 239 plastic items out of a total of 638 litter pieces.
- The Clean Coast Index (CCI) revealed beach cleanliness varied significantly, ranging from Clean (2-5) to Extremely Dirty (over 20), particularly near the port area.
- The findings highlighted that PVC was the predominant type of plastic litter, and the study also discussed the sources of waste and compared the CCI with other international locations.
We report the first record of the microlepidopteran beyond the South Shetland Islands at the Chilean Yelcho scientific station (64°52'33.1428″ S; 63°35'1.9572″ W), Doumer Island, close to the west coast of the Antarctic Peninsula.

The adherens junction complex, composed mainly of vascular endothelial (VE)-cadherin, β-catenin, p120, and γ-catenin, is the main element of the endothelial barrier in postcapillary venules.S-nitrosylation of β-catenin and p120 is an important step in proinflammatory agents-induced hyperpermeability. We investigated in vitro and in vivo whether or not VE-cadherin isS-nitrosylated using platelet-activating factor (PAF) as agonist.

The effects of adding nitrate (NO₃(-)) to natural phytoplankton assemblages were evaluated considering biomass, cell abundance, and taxonomic composition. Microcosm experiments were performed in the spring, summer, and winter in the Comau Fjord located in Subantarctic Patagonia.
