Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, EarlyView.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

First archaeological evidence for ginger consumption as a potential medicinal ingredient in a late medieval leprosarium at St Leonard, Peterborough, England

open access: yesScientific Reports
Leprosy was one of the most outwardly visible diseases in the European Middle Ages, a period during which leprosaria were founded to provide space for the sick.

Early cave art and ancient DNA record the origin of European bison

open access: yesNature Communications, 2016
The ancestry of the European bison (wisent) remains a mystery. Here, Cooper and colleagues examine ancient DNA from fossil remains of extinct bison, and reveal the wisent originated through the hybridization of the extinct Steppe bison and ancestors of ...

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

open access: yesiMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Assessment of Gold‐Mediated Male Reproductive Dysfunction in Male WISTAR Rats Through Sperm Analysis and Testosterone Measurement

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Gold has been used for centuries in both ornamental and medicinal contexts. More recently, gold compounds, containing ions or nanoparticles, have attracted attention for their anti‐inflammatory, anticancer, and diagnostic applications. Therefore, concerns about systemic toxicity and biodistribution have prompted investigations into the ...

Comment: Characterization of Two Historic Smallpox Specimens from a Czech Museum

open access: yesViruses, 2017
The complete genome sequences of two strains of variola virus (VARV) sampled from human smallpox specimens present in the Czech National Museum, Prague, were recently determined, with one of the sequences estimated to date to the mid-19th century.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Phenolic Profile and Susceptibility to Fusarium Infection of Pigmented Maize Cultivars

open access: yesFrontiers in Plant Science, 2018
Maize is a staple food source in the world, whose ancient varieties or landraces are receiving a growing attention. In this work, two Italian maize cultivars with pigmented kernels and one inbred line were investigated for untargeted phenolic profile, in

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.
