Constraining the Cratering Chronology of Vesta

open access: yes, 2014
Vesta has a complex cratering history, with ancient terrains as well as recent large impacts that have led to regional resurfacing. Crater counts can help constrain the relative ages of different units on Vesta's surface, but converting those crater ...

Towards the Recapitulation of Ancient History in the Laboratory: Combining Synthetic Biology with Experimental Evolution [PDF]

open access: yesIEEE Symposium on Artificial Life, 2012
One way to understand the role history plays on evolutionary trajectories is by giving ancient life a second opportunity to evolve. Our ability to empirically perform such an experiment, however, is limited by current experimental designs.

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

open access: yesFEBS Open Bio, EarlyView.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Ancient West African foragers in the context of African population history

open access: yesNature, 2019
Our knowledge of ancient human population structure in sub-Saharan Africa, particularly prior to the advent of food production, remains limited. Here we report genome-wide DNA data from four children—two of whom were buried approximately 8,000 years ago ...

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Northern Connections: Interregional Contacts in Bronze Age Northern and Middle Sweden

open access: yesOpen Archaeology, 2020
This article examines northern connections in the Nordic Bronze Age, focusing on interregional contacts in middle and northern Sweden. In the article, we argue that it is important to incorporate a northern perspective in the discussions about the ...

open access: yesTheoretical Roman Archaeology Journal, 2022
Over the last few decades, a critical revision of prior scholarship concerning Roman domestic space has led to the reappraisal of the traditional account of the atrium suggesting a possibility for this space to be ‘unroofed’.
