Let's Talk About Bone Cylinders. Taphonomy of Carnivores and Humans
International Journal of Osteoarchaeology, EarlyView.ABSTRACTBone cylinders are a distinctive structure predominantly produced by durophagous carnivoran species during the consumption of long bones, in which the diaphyseal canal remains intact while both epiphyses are removed or consumed. This study evaluates the significance of this morphology, traditionally attributed to extant and extinct hyena ...

People and Nature, EarlyView.Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies

People are good at stewardship
People and Nature, EarlyView.Abstract Environmental sciences and policy have long been framed on the premise that environmental harm is an expression of human nature rather than a product of specific historical and political arrangements. This framing has shaped a generation of interventions designed to constrain human behaviour rather than enable human capacity.

Polymer Engineering &Science, EarlyView.Thermoresistive sensing materials derived from eco‐friendly polymers for broad‐range temperature measurements. ABSTRACT Carbon dioxide‐derived polycarbonates (CO2‐PCs) present a sustainable alternative to standard bisphenol A polycarbonates (BPA‐PCs), as they are synthesized from the reaction between epoxide and carbon dioxide (CO2). In fact, these eco‐

Polymer Engineering &Science, EarlyView.This illustration shows polyamide 6 (PA6) blended with 20–50% polybutylene succinate (PBS) by volume. The balance between tensile properties, fracture toughness and self‐healing capability is achieved in the 30% vol PBS blend. Thermal healing at 140°C results in 40% fracture toughness recovery in a blend containing 30% vol PBS.

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor
Progress in Photovoltaics: Research and Applications, EarlyView.A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.
