ABSTRACT Complex stratigraphic arrangements may be generated through lateral facies transitions from the strata of aeolian depositional systems into bordering peritidal deposits. In such scenarios, sedimentary architectural complexity and associated facies heterogeneities are governed by the interplay between autogenic processes inherent to tidal ...

Biological and biologically‐inspired functional nanostructures with structural, thermal, optical, and sensing applications are reviewed. The role of nanoscale features in biological materials on performance is described, and their blueprints are used for bio‐inspired nanomaterials, synthesized using advanced techniques (i.e., photolithography, bio ...

ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...

Abstract Modern technological evolution witnesses a fast‐paced progress in the design, science, and technology of light‐driven micro/nanomachines in the recent past. These micromachines have found enormous applications as micro/nanoscale manipulators, micromachined space exploration components, nano‐sized cell positioning and control, and micro ...

Jurassic jeopardy—life and death on an ancient seafloor
The Lower Jurassic Down Cliff Sand Member of the Dorset coast, southern England, is a rich source of marine invertebrate fossils. Among these are echinoderms and less common arthropods. Despite having multi‐component skeletons that are prone to disarticulation, remains of some of these are remarkably complete.

ABSTRACT The site of Loreto (Venosa Basin, Italy) was first discovered in 1929 and subsequently excavated during the latter half of the 20th century. The excavation revealed three archaeo‐palaeontological levels, with the lowermost level (Level A) yielding the largest number of remains.

Abstract The Australian Cambrian stratigraphic record is one of the most complete for any continent. However, there is a general division, with older Cambrian rocks in South Australia (predominantly Terreneuvian, Stage 2 to Miaolingian, Wuliuan) and younger rocks in northern Australia (mostly latest Series 2, Stage 4 and younger), with minimal ...

A new insect boring in fossil wood from the Iranian Upper Cretaceous
Abstract Here we describe Iranichnus farsensis igen. et isp. nov., a bioerosion trace in fossil wood characterized by a system of sinuous channels in the wood under the bark, also bearing small borings radially oriented within the channels. We attributed this to insects, most probably a beetle from one of the groups known to feed on wood just under the

ABSTRACT Recent interest in Mg‐rich silicate formation stems from its role as a valuable palaeoclimatic indicator in fluvio‐lacustrine environments and its insights into metal geochemical cycling. Traditionally, Mg‐silicate genesis in lacustrine contexts is linked to alkaline or saline conditions in closed, evaporitic basins.

Macrofaunal contributions to benthic nutrient fluxes revealed by radium disequilibrium
Abstract The benthic flux of nutrients underpins marine food webs, influences conditions for life in the oceans, and contributes to climatic feedback. Estimates of these fluxes' contributions to macro‐ and micronutrient cycles are, however, highly variable, generating significant uncertainty in biogeochemical models.
