Turns out that if you use a broom to scratch yourself everyone thinks you're a weirdo but if a cow does it they end up in the cover of Current Biology

Springer Nature post on the birthday of Sofia Kovalevskaya, with a fun fact "Did you know? Sofia Kovalevskaya was not only a groundbreaking mathematician but also a novelist and advocate for women’s education. Her work opened doors for women in academia across Europe", and a quote by her: "It is impossible to be a mathematician without being a poet in soul."

Mummified cave cheetahs inform rewilding actions in Saudi Arabia - Communications Earth & Environment Naturally mummified cheetah remains in a Saudi Arabian cave system with radiocarbon-calibrated ages between about 4,200 and 100 years cluster with Asian as well as West-African sub-species, with implications for rewilding efforts, suggests a genomic analysis of the remains.

Seven naturally mummified cheetahs found in caves northern Saudi Arabia show at least two subspecies once roamed the Arabian Peninsula, offering hope for future reintroduction of cheetahs to the peninsula.

It took 35 years for T. rex to become fully grown | CNN Tyrannosaurus rex lived longer and took more time to reach its maximum size than previously thought, according to a new study.

How long did it take for T. rex to grow from a hatchling into a bus-sized bone-cruncher?

Longer than we used to think! Maybe up to 40 years!

El Gobiermo impulsa la inclusión del lobo en el Libro Rojo de especies vulnerables La comunidad científica respalda la catalogación por el deterioro de la única población ibérica

🔴 La población ibérica de lobo será incluida en el Libro Rojo de las Especies Vulnerables.

Esta decisión se apoya, según nuestro investigador Alberto Fernández Gil, «en un proceso científico reglado y en la mejor información disponible, muy alejado de decisiones políticas o territoriales».

Session #256
COLLAPSE, MOBILITY, AND RENEWAL: RETHINKING THE CHALCOLITHIC–BRONZE AGE TRANSITION IN SOUTHEASTERN EUROPE AND THE BLACK SEA REGION


From the end of the 5th millennium BC through the 4th millennium BC, the transition from the Late Neolithic and Chalcolithic to the Early Bronze Age in Southeastern Europe and around the Black Sea marks one of the most dynamic and debated periods in
Eurasian prehistory. Across this geographical area, a dramatic decline in the density of archaeological evidence occurred: long-lived settlements were abandoned, new types of material culture appeared, and population movements—both local and longdistance—reshaped social and economic networks. This session aims to explore what triggered these transformations and how they unfolded in different regions.

We invite contributions employing a wide range of analytical, contextual, and interpretative approaches to investigate this crucial turning point: refined chronologies through radiocarbon dating; bioarchaeological, isotopic, and ancient DNA data to trace
population mobility, diet, and provenance; studies of ceramic residues and environmental proxies (pollen, sediments, fauna) to reconstruct subsistence strategies and landscape change; as well as archaeological, zooarchaeological, and anthropological perspectives addressing material culture, settlement patterns, and social organisation. By integrating these diverse datasets, the session seeks to address fundamental questions: Was there a demographic replacement, or rather an adaptation of existing
groups to new cultural paradigms and economic lifeways? What role did climate fluctuations play in settlement reorganisation and mobility? And how can interdisciplinary research help to build a more nuanced picture of this transformative era?

The Romanian contribution to this session was supported by a grant from the Romanian Ministry of Education and Research, CNCS-UEFISCDI, project number PN-IV-P1-PCE-2023-1899 (BioArhSteppe).

(A) Genomic inbreeding coefficient (FROH) of imputed and modern dogs plotted as a function of time, calculated based on ROH. Imputed samples are colored based on their geographic grouping, while modern samples are colored in gray. A loess regression was applied with each colored shaded area depicting the SE. (B) Total number of ROH segments plotted against total ROH length for the imputed dogs. Colors correspond to age of imputed samples in years before present (ybp)., while modern samples belonging to each dog group are colored in gray. (C) Map of imputed dog samples colored by their inbreeding coefficient (FROH). Samples with FROH values above 0.1 are indicated.

My photo collage shows four pottery vessels, all a creamy yellow in colour, with black painted decoration depicting underwater sea-life featuring lively stylised octopuses with writhing tentacles (arms), All on display at Heraklion Archaeological Museum, Crete. 

Top L - Minoan pithoid storage jar decorated in the “Marine Style” with wide-eyes octopus, argonauts, rocks, and coral. Rounded top tapering down to a narrower base. Short cyclindrical neck flaring out at the mouth with black wavy decoration reminiscent of waves. Loop handles attached to the shoulders of the body. Height 55 cm. From Zakros. 1500-1450 BC

Top R - Minoan flask with a rounded body, short cyclindrical neck which flares at the rim, and two small curved handles attached between the top of the spout and the shoulders of the body. Decorated in “Marine Style” which depicts an almost cartoon-like octopus with wide eyes and sucker-lined tentacles which writhe around the vase. Other decorative sea-motifs include sea urchins, seaweed and rocks. Height 27cm. From Palaikastro, 1500-1450 BC

Bottom L - alabastron, broad at the base, swelling outwards into a fuller belly before narrowing near the top with a very short cyclindrical neck and a wider flat rimmed mouth. Decorated in “Marine Style” with a wide-eyed octopus among rocks. From Knossos Little Palace, 1450-1370 BC

Bottom R - krater with rounded body narrowing at the bottom towards the foot. Wide flaring mouth and rim with black painted wavy decoration, and two sturdy handles attached on each side between the top of the mouth and shoulders of the vessel. Decorated with a central very stylised wide-eyed octopus whose tentacles loop up and down around the body of the pot, 1370-1300 BC
