Light‐driven micro/nanobots

open access: yesNanophotonics, Volume 14, Issue 27, Page 4821-4874, December 2025.
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

open access: yesGeology Today, Volume 41, Issue 6, Page 244-250, November/December 2025.
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.

Die Torsion der Gastropoda ‐ ein biomechanischer Prozeß

open access: yes, 2009
The recently proposed biomechanical model of gastropod torsion (edlinger 1988 a, b) is rejected on various reasons. First, the assumed original conditions in Polyplacophora and Tryblidiida as well as the constructed original condition in the Gastropoda ...

Hominin and carnivore roles during the formation of the early Middle Pleistocene site of Loreto (Venosa Basin, southern Italy)

open access: yesJournal of Quaternary Science, Volume 40, Issue 7, Page 1252-1268, October 2025.
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.

Beiträge zur Torsion und Frühevolution der Gastropoden

open access: yes, 2009
Contributions to torsion and early evolution of the gastropods The phylogenetical model, which is presented here, is directed by trying to explain torsion of gastropods out of biomechanical conditions.

Biostratigraphy and correlation of the Cambrian Series 2 (Stage 4) to Miaolingian (Wuliuan) Thorntonia Limestone, south‐eastern Georgina Basin (Queensland, Australia)

open access: yesPapers in Palaeontology, Volume 11, Issue 5, September/October 2025.
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

open access: yesPalaeontology, Volume 68, Issue 5, September/October 2025.
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
