Ditched and walled enclosures in Prehistoric Iberia (4th-3rd millennia cal. BCE): Like oil and water

open access: yesLucentum
Iberian Copper Age «ditched» and «walled» enclosure sites are often thought to represent two clearly distinguishable groups of sites. However, the discovery of sites where both ditches and walls are present («mixed sites») complicates things.

New evidence for prehistoric copper metallurgy in the vicinity of Bor [PDF]

open access: yesStarinar, 2016
The last three years of archaeological investigations at the site Ru`ana in Banjsko Polje, in the immediate vicinity of Bor, have provided new evidence regarding the role of non-ferrous metallurgy in the economy of the prehistoric communities of

The ‘Copper Age’—A History of the Concept [PDF]

open access: yesJournal of World Prehistory, 2019
The idea that there was a Copper Age between the Neolithic and Bronze Age was inspired by the discovery of the use of native copper in prehistoric North America. Its currency in European prehistory owes much to the 1861 observations by William Wilde that copper tools preceded the use of bronze in Ireland, though Wilde did not postulate a Copper Age per

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Copper in Ancient India [PDF]

open access: yes, 1918
So far as India is concerned, it appears that copper was known in the later Vedic age and specially in the Brahman age, and it does not appear to have been mentioned in the Rig-Veda, the earliest of the Vedas.

The potential to control Haemonchus contortus in indigenous South African goats with copper oxide wire particles [PDF]

open access: yes, 2009
The high prevalence of resistance of Haemonchus contortus to all major anthelmintic groups has prompted investigations into alternative control methods in South Africa, including the use of copper oxide wire particle (COWP) boluses.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

open access: yesFEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

open access: yesFEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...
