Modulation of swimming in the gastropod Melibe leonina by nitric oxide [PDF]

open access: yes, 2002
Nitric oxide (NO) is a gaseous intercellular messenger produced by the enzyme nitric oxide synthase. It has been implicated as a neuromodulator in several groups of animals, including gastropods, crustaceans and mammals.

A >300 Myr Long‐Lived Topographic Highland Along the Northern North China Craton Margin Driven by Multistage Continental Convergence

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.

A gas-liquid solid phase peptide and protein sequenator [PDF]

open access: yes, 1981
A new miniaturized protein and peptide sequenator has been constructed which uses gas phase reagents at the coupling and cleavage steps of the Edman degradation. The sample is embedded in a matrix of Polybrene dried onto a porous glass fiber disc located

On the Influence of Mineral Dust on Glacial Albedo at Nevado Huascarán (Cordillera Blanca, Peru)

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract In addition to warming and hydrological changes, glacier retreat is influenced by mineral dust and other light absorbing impurities. However, very little is known about the presence of mineral dust in the tropical Andes, making it difficult to model the radiative impact of dust on glacial surfaces.

Trichoplax, the simplest known animal, contains an estrogen-related receptor: Implications for the evolution of vertebrate and invertebrate estrogen receptors [PDF]

open access: yes, 2008
Although, as their names imply, vertebrate and invertebrate estrogen receptors [ERs] and estrogen-related receptors [ERRs] are related transcription factors, their evolutionary relationships to each other are not fully understood.

Impressive. Memory, Matter and Mind [PDF]

open access: yes, 2011
This paper will set out a dualistic pattern, exemplified by (1) a neurobiological account of memory and (2) a short segment of the work of an Austrian avantgarde film-maker.

A rapamycin-sensitive signaling pathway contributes to long-term synaptic plasticity in the hippocampus [PDF]

open access: yes, 2002
Many forms of long-lasting behavioral and synaptic plasticity require the synthesis of new proteins. For example, long-term potentiation (LTIP) that endures for more than an hour requires both transcription and translation.

Observations on the feeding regime of the sea hare aplysia, Donabella rumphi (Cuvier) and its captive spawning and larval rearing trials [PDF]

open access: yes, 2008
Aplysia occurs in a variety of color patterns that correlate with the seaweed upon which it is feeding and living. Aplysia which is a gastropod mollusc is one of the important candidates for marine aquarium.

Model Checking Tap Withdrawal in C. Elegans

open access: yes, 2015
We present what we believe to be the first formal verification of a biologically realistic (nonlinear ODE) model of a neural circuit in a multicellular organism: Tap Withdrawal (TW) in \emph{C. Elegans}, the common roundworm.

Functional Adaptations of Hemocytes of Aplysia depilans (Gmelin, 1791) and Their Putative Role in Neuronal Regeneration

open access: yesFishes
Invertebrates show great diversity in their responses to neural damage. Numerous invertebrate phyla, including gastropods, can replace all or a portion of their nervous systems.
