Anadolu Prehistoryasında Direkli Mağarası Kazıları ve Buluntuları

open access: yesHöyük
Anadolu arkeolojisinde mağara içi yerleşim ve kültürlerinin araştırılma tarihi çok eskilere dayanmaktadır. 1845 yılında Yarımburgaz Mağarası’nın, 1945 yılında Karain Mağarası’nın keşfinin ardından; on bir yıl sonra (1956) Öküzini Mağarası kazılarının ve ...

The lives of creatures obscure, misunderstood, and wonderful: a volume in honour of Ken Aplin 1958–2019. In Papers in Honour of Ken Aplin, ed. Julien Louys, Sue O’Connor, and Kristofer M. Helgen

open access: yesRecords of the Australian Museum, 2020
[Excerpt] He was always a modest man, but Ken was a genius and the toughest man we knew. He was also extraordinarily generous of spirit. The way he gave of himself, his time, and his hard-won stores of knowledge, was legendary amongst his friends and ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Tracking Holocene drift-ice limits on the northwest–southwest Iceland shelf: Comparing proxy data with observation and historical evidence

open access: yesArctic, Antarctic, and Alpine Research, 2019
We detail variations in the weight percent (wt%) of quartz, a proxy for drift ice, in fifteen marine sediment cores from the northwest, west, and southwest Iceland shelf throughout the past 10 cal ka BP.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Winter air temperature in Holocene reconstructed from the ice wedges stable water isotopes near Anadyr town

open access: yesЛëд и снег, 2019
The object of research is syncryogenic Holocene strata on the coast of the Onemen Bay, 2 km from the town of Anadyr. In July 2017, the outcrop of the first marine terrace uncovered by strong storms was examined.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
