Evaluating the character and preservation of DNA within allophane clusters in buried soils on Holocene tephras, northern New Zealand [PDF]

open access: yes, 2012
Clay minerals possess sorptive capacities for organic and inorganic matter, including DNA (Lorenz and Wackernagel, 1994), and hence reduce the utilization and degradation of organic matter or DNA by microorganisms. Buried allophane-rich soils on tephras (

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Phytochemical‐Based Strategies for Lung Cancer: Clinical Insights Into Pleiotropic Molecular Signaling and Therapeutic Roles

open access: yesPhytotherapy Research, EarlyView.
Lung cancer (LC) remains the leading cause of global cancer‐related death. Phytochemicals from medicinal plants are increasingly being considered as potential LC treatment agents due to their multi‐targeted action, safety, and accessibility. These have anticancer properties by regulating key molecular signaling pathways.

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Hurdles in investigating UVB damage in the putative ancient asexual Darwinula stevensoni (Ostracoda, Crustacea) [PDF]

open access: yes, 2013
Ostracoda or mussel-shrimps are small, bivalved Crustacea. Because of their excellent fossil record and their broad variety of reproductive modes, ostracods are of great interest as a model group in ecological and evolutionary research.

Designer DNA‐Based Machines

open access: yesSmartBot, EarlyView.
DNA machinery represents a burgeoning frontier at the intersection of robotics and nanotechnology, evolving from static nanostructure toward dynamic nanorobots. Here, the authors review the comprehensive research pipeline of designer DNA‐based nanomachines, covering the design, analysis, and fabrication. These programmable systems enable transformative

Electroelution Into a Salt Trap: Reviving an Old‐School Approach to DNA Purification

open access: yesSmall Methods, EarlyView.
Electroelution into a salt cushion is a well‐established yet underutilized method of capturing gel‐purified nucleic acids. This Perspective discusses how this traditional method can be reengineered to meet the demands of next‐generation technologies, such as long‐read sequencing.

Genetic transitions in the Neolithic and Bronze Age at Mas d’en Boixos (Catalonia, Spain)

open access: yesiScience
Summary: Mas d’en Boixos is a key prehistoric site in Northeastern Iberia spanning from the Early Neolithic to the Late Iron Age. We analyzed genome-wide data from eight individuals and ten mitogenomes, dated to the Middle Neolithic and Early Bronze Age,

Synthesis of Sustainable Chromium‐Based Nanoparticles With Fluorescence Tunable Ability for Biosensing of Tumor‐Derived Exosomes and Molecular Information Protection

open access: yesSusMat, EarlyView.
The study uses rapidly prepared Cr NPs with controllable fluorescence, enabling co‐regulation of quenching and enhancement for dyes and DNA of differing structures. By assembling a CD63‐specific aptamer with Cr NPs, it creates a quantitative readout for CD63‐positive TDEs.

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The
