- Beyond the rhetoric of “sustainable aviation”: a counterfactual confrontationPublication . Gössling, Stefan; Hopkins, Debbie; Schweiggart, Nadja; Cohen, Scott; Cocolas, Nicole; Higham, JamesAmid evidence of rising emissions, the aviation industry continues to promote demand growth while offering long-term sustainability reassurances communicated as “facts.” Using counterfactual analysis, this paper examines how industry rhetoric constructs and defends these discursive strategies. Drawing on a content analysis of 211 sources – including airline websites, industry reports, and manufacturer statements – the study identifies seven discursive strategies. The findings reveal a novel theoretical mechanism, “future soothing”: projecting technological salvation into a perpetually deferred future to ease public concern and postpone regulation. By transforming delay into the illusion of progress, discourses operate as rhetorical governance, sustaining growth under the guise of climate responsibility. The paper contributes to scholarship on the temporal politics of sustainability, showing how appeals to the future enable inaction in the present and illustrating how rhetoric, temporality, and power intertwine in shaping societal responses to climate change. Breaking aviation’s “cycle of blame” requires policymaker action.
- Anthony E. Marks (1938–2025): pioneer of the palaeolithicPublication . Rose, Jeffrey Ian; Bicho, Nuno; Usyk, Vitaly I.; Winchell, FrankAnthony “Tony” Edward Marks passed away on August 15, 2025, at his home in Santa Fe, New Mexico, at the age of 87. Tony’s passing marks the end of a remarkable career in archaeology that spanned nine countries, four continents, and a quarter million years of prehistory. Not only did he fundamentally shape how we understand the Palaeolithic record, but he transformed our very perception of lithic technology, teaching us how to find the profound depth of meaning in stone. A proud New Yorker, Tony was born, raised, and edu¬cated in Manhattan. As a young student at Columbia Uni¬versity eager to pursue his love of European medieval art and churches, he was promptly taken aside by the anthropol¬ogy department head, Marvin Harris, who (rather forcefully as Tony would recall) urged him to stick with archaeology. Tony’s professional career began with the UNESCO Nubian salvage campaigns of the 1960s. As Lake Nasser rose behind the Aswan High Dam, Tony mapped prehistoric sites along the east bank of the Nile before their inundation. During the Nubian salvage project, he documented several key Palaeo¬lithic industries, including an array of assemblages defined by the presence of Nubian core technology. He could never know at the time how that discovery would unexpectedly resurface decades later, at the end of his career.
- First insights on chemical nature and bioactivity of surface mucus from the Antarctic sponges Mycale (Oxymycale) acerata and Dendrilla antarcticaPublication . Rizzo, Carmen; Silva, José Paulo da; Lauritano, Chiara; Montuori, Eleonora; Papale, Maria; Giudice, Angelina LoThe mucus produced by the Antarctic sponge species Mycale (Oxymycale) acerata and Dendrilla antarctica was ana¬lyzed to investigate its chemical composition and assess potential cytotoxic activity against human tumor cell lines. The mucus samples exhibited a high-water content (98–99%), while inorganic salts represented most of the total dry weight (67.1 ± 2.3%). Sodium was the most abundant element, accounting for 75% in D. antarctica and up to 82% in M. acerata. Other major elements—including magnesium, potassium, and calcium—comprised 3–10% of the inorganic fraction. Pro¬tein content was estimated at 0.44% for M. acerata and 5.63% for D. antarctica, with a carbon-to-nitrogen (C/N) ratio between 3 and 5. Elemental analysis was supported by μFT-IR spectroscopy, which confirmed the presence of inorganic salts, water, and proteinaceous materials. Further characterization by 1H NMR spectroscopy and LC–MS revealed the pres¬ence of amino acids, peptides, sugars, carboxylic acids, nitrogenous bases, and their derivatives. Notably, oxylipin concen¬trations ranged between 1 and 3 ng/L. In addition, M. acerata mucus demonstrated antiproliferative activity, selectively inhibiting the growth of Malme-3 M melanoma cell lines, thus suggesting a potential for cytotoxic effects. Overall, these findings provide the first chemical characterization of Antarctic sponge mucus, providing first insights for its potential exploitation as a novel source of bioactive compounds.
