A chromosome-level genome of the giant vinegaroon Mastigoproctus giganteus exhibits the signature of pre-Silurian whole genome duplication.

Within the arachnids, chromosome-level genome assemblies have greatly accelerated the understanding of gene family evolution and developmental genomics in key groups, such as spiders (Araneae), mites and ticks (Acariformes and Parasitiformes). Among other poorly studied arachnid orders that lack genome assemblies altogether are the clade Pedipalpi, which is comprised of three orders that form the sister group of spiders, which diverged over 400 Mya. We close this gap by generating the first chromosome-level assembly from a single specimen of the vinegaroon Mastigoproctus giganteus (Uropygi).

We present an interdisciplinary analysis of finds from the Trypillia settlement of Kosenivka, Ukraine (ca. 3700-3600 BCE, Trypillia C1-2), that links information on human, faunal, and botanical remains with archaeological data to provide exceptionally detailed insights into life and death at a giant Trypillia settlement. We obtained osteological, palaeopathological, morphological and histotaphonomic data from human bone fragments; performed carbon and nitrogen stable isotopic analysis of human and animal bone to calculate food webs; modelled newly generated radiocarbon dates to refine the site's chronology; and contextualised the finds within the phenomenon of a general lack of human remains in Early and Middle Trypillia times through a literature review.

Article Synopsis
- - A 67-year-old woman had a giant ancient schwannoma tumor in her left atrium that required complex surgical removal.
- - The surgery involved a challenging procedure with extensive resections in both atria and the interatrial septum.
- - The modified superior trans-septal approach was used, allowing for reconstruction without the need for auto-transplantation.

Amphibian declines, driven by climate change (e.g., shifting temperatures, altered precipitation) and human activities like deforestation, agriculture, and urbanization, may lead to local extinctions.

The remarkable glyptodonts have sparked the interest of evolutionary biologists since the 19th century, in their attempts to elucidate the phylogenetic relationships among the various species of these armored giants and their relationship with other xenarthrans. In recent years, the molecular analysis of the first glyptodont has included them within the cingulates, as a special group of armadillos that lost the mobility of the bands of their armor during their evolutionary history. In this research, we obtained the mitochondrial DNA sequence of the elusive and poorly known glyptodont Neuryurus rudis, inferring its phylogenetic position with respect to the glyptodont Doedicurus sp.
