Female burials equipped with weapons, a topic of interest among scholars and the general public, remain rare occurrences in archaeological records. The interpretation of such cases requires an interdisciplinary approach and a comprehensive evaluation of the available evidence, particularly regarding the sex and potential lifestyle of the deceased. Consequently, data on specific populations, regions, and time periods remain scarce.

The Aba family played a pivotal role in Medieval Hungary, dominating vast territories and producing influential figures. We conducted an archaeogenetic study on remains from the necropolis in Abasár, the political center of the Aba clan, to identify family members and explore their genetic origins. Using Whole Genome Sequencing (WGS) data from 19 individuals and radiocarbon dating, we identified 6 Aba family members with close kinship ties.

Tuberculosis (TB) is a bacterial infection that is well-known in the palaeopathological record because it can affect the skeleton and consequently leaves readily identifiable macroscopic alterations. Palaeopathological case studies provide invaluable information about the spatio-temporal distribution of TB in the past. This is true for those archaeological periods and geographical regions from when and where no or very few TB cases have been published until now-as in the Sarmatian period (1st-5th centuries CE) in the Barbaricum of the Carpathian Basin.

In the last year two publications shed new light on the linguistic and genomic history of ancient Uralic speakers. Here I show that these novel genetic and linguistic data are compatible with each-other and with the archaeological inferences, allowing us to formulate a very plausible hypothesis about the prehistory of Ugric speakers. Both genetic and archaeological data indicate the admixture of the Mezhovskaya population with northern forest hunters in the late Bronze Age, which gave rise to a "proto-Ugric" community.

Kinship analysis from very low-coverage ancient sequences has been possible up to the second degree with large uncertainties. We propose a new, accurate, and fast method, correctKin, to estimate the kinship coefficient and the confidence interval using low-coverage ancient data. We perform simulations and also validate correctKin on experimental modern and ancient data with widely different genome coverages (0.

The Hunyadi family is one of the most influential families in the history of Central Europe in the 14th-16th centuries. The family's prestige was established by Johannes Hunyadi, a Turk-beater who rose to the position of governor of the Kingdom of Hungary. His second son, Matthias Hunyadi, became the elected ruler of the Kingdom of Hungary in 1458.

Huns, Avars, and conquering Hungarians were migration-period nomadic tribal confederations that arrived in three successive waves in the Carpathian Basin between the 5 and 9 centuries. Based on the historical data, each of these groups are thought to have arrived from Asia, although their exact origin and relation to other ancient and modern populations have been debated. Recently, hundreds of ancient genomes were analyzed from Central Asia, Mongolia, and China, from which we aimed to identify putative source populations for the above-mentioned groups.

Article Synopsis
  • The Gepids were a Germanic tribe that settled in the Carpathian Basin during the Migration Period, becoming allies of the Huns and later forming an independent kingdom after the fall of the Hun Empire.
  • Due to limited historical and archaeological evidence, there's ongoing debate about the origins and makeup of these populations, prompting new research into their genetic legacy.
  • The study analyzed 46 complete mitochondrial genomes from Gepid cemeteries in Transylvania dating to the late 5th and early 6th centuries AD, revealing that the Gepids primarily descended from Northwestern European lineages, which contributed significantly to their genetic structure.

We introduce a novel population genetic approach suitable to model the origin and relationships of populations, using new computation methods analyzing Hg frequency distributions. Hgs were selected into groups which show correlated frequencies in subsets of populations, based on the assumption that correlations were established in ancient separation, migration and admixture processes. Populations are defined with this universal Hg database, then using unsupervised artificial intelligence, central vectors (CVs) are determined from local condensations of the Hg-distribution vectors in the multidimensional point system.

Article Synopsis
  • Nomadic Hungarian groups significantly influenced the early population of Hungary, but genetic data mainly focuses on the elite class rather than commoners.
  • Analysis of 202 individual mitogenomes reveals that the genetic makeup of 10-11th century commoners differs from that of the elite, showing closer affinities to local European populations.
  • There is evidence of genetic admixture between the elite immigrants and local commoners, suggesting that most commoners were likely local inhabitants who mixed with the incoming Hungarian groups.

Cell mediated immunity of the honey bee (Apis mellifera) involves the activity of several hemocyte populations, currently defined by morphological features and lectin binding characteristics. The objective of the present study was to identify molecular markers capable of characterizing subsets of honey bee hemocytes. We developed and employed monoclonal antibodies with restricted reactions to functionally distinct hemocyte subpopulations.

Hun, Avar and conquering Hungarian nomadic groups arrived to the Carpathian Basin from the Eurasian Steppes and significantly influenced its political and ethnical landscape, however their origin remains largely unknown. In order to shed light on the genetic affinity of above groups we have determined Y chromosomal haplogroups and autosomal loci, suitable to predict biogeographic ancestry, from 49 individuals, supposed to represent the power/military elit. Haplogroups from the Hun-age are consistent with Xiongnu ancestry of European Huns.

It has been widely accepted that the Finno-Ugric Hungarian language, originated from proto Uralic people, was brought into the Carpathian Basin by the conquering Hungarians. From the middle of the 19th century this view prevailed against the deep-rooted Hungarian Hun tradition, maintained in folk memory as well as in Hungarian and foreign written medieval sources, which claimed that Hungarians were kinsfolk of the Huns. In order to shed light on the genetic origin of the Conquerors we sequenced 102 mitogenomes from early Conqueror cemeteries and compared them to sequences of all available databases.

Seven different models are applied to the same problem of simulating the Sun's coronal magnetic field during the solar eclipse on 2015 March 20. All of the models are non-potential, allowing for free magnetic energy, but the associated electric currents are developed in significantly different ways. This is not a direct comparison of the coronal modelling techniques, in that the different models also use different photospheric boundary conditions, reflecting the range of approaches currently used in the community.

Solar eruptions are the main driver of space-weather disturbances at the Earth. Extreme events are of particular interest, not only because of the scientific challenges they pose, but also because of their possible societal consequences. Here we present a magnetohydrodynamic (MHD) simulation of the 14 July 2000 "Bastille Day" eruption, which produced a very strong geomagnetic storm.

The identification of molecular markers considerably facilitated the classification and functional analysis of blood cell types. Apis mellifera hemocytes have been classified by morphological criteria and lectin binding properties; however, the use of molecular markers has been minimal. Here we describe a monoclonal antibody to a non-phagocytic subpopulation of A.

Article Synopsis
  • Researchers are building a detailed genetic database of medieval Hungarian conquerors by resequencing the entire mitochondrial DNA (mtDNA) of 24 ancient samples using advanced sequencing technology.
  • Traditional PCR methods used for genetic sequencing often lead to incorrect identification of haplotypes and haplogroups due to their susceptibility to ambiguous sequence reads.
  • The SNaPshot method, combined with established criteria for ancient DNA authenticity, offers a cost-effective and efficient way to analyze coding region SNPs for accurate haplogroup classification.

Telomere length in Drosophila is maintained by targeted transposition of three non-LTR retrotransposons: HeT-A, TART and TAHRE (HTT), but understanding the regulation of this process is hindered by our poor knowledge of HTT associated proteins. We have identified new protein components of the HTT array: Chromator (Chro), the TRF2/DREF complex and the sumoylation machinery. Chro was localized on telomeric HTT arrays by immunostaining, where it may interact with Prod directly, as indicated by yeast two-hybrid interaction, co-IP, and colocalization on polytene chromosomes.

We report in this paper that the PROD protein, encoded by the gene proliferation disrupter (prod), is associated with the telomeric chromatin in Drosophila melanogaster. It binds to a region just upstream of the promoter of the telomere-specific retrotransposon HeT-A, which is located in the long 3'untranslated region of the element near its oligo(A) tail. Reduction of PROD in prod heterozygote flies results in elevated levels of HeT-A RNA in the ovaries, suggesting that PROD functions as a repressor of HeT-A transcriptional activity at the telomeres.

Chromosome length in Drosophila is maintained by targeted transposition of three non-long terminal repeat retrotransposons, HeT-A, TART, and TAHRE, to the chromosome ends. The length and composition of these retrotransposon arrays can vary significantly between chromosome tips and between fly stocks, but the significance and consequences of these length differences are not understood. A dominant genetic factor, Tel, has been described, which causes a severalfold elongation of the retrotransposon arrays at all telomeres.
