Possible origins of macroscopic left-right asymmetry in organisms

open access: yes, 2012
I consider the microscopic mechanisms by which a particular left-right (L/R) asymmetry is generated at the organism level from the microscopic handedness of cytoskeletal molecules.

Corallorhiza striata is the first example of a pseudocopulatory orchid in North America and an instance of “double deception” in fully mycoheterotrophic plants

open access: yesAmerican Journal of Botany, Volume 113, Issue 4, April 2026.
Abstract Premise Orchids have many pollination strategies, from highly species‐specific mutualisms with insects to deceit pollination, including sexual deception. The family also has the most leafless, parasitic species (mycoheterotrophs) of any plant family.

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 177-198, April 2026.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

open access: yesBoreas, Volume 55, Issue 2, Page 585-599, April 2026.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Alpha9 nicotinic acetylcholine receptors and the treatment of pain [PDF]

open access: yes, 2009
Chronic pain is a vexing worldwide problem that causes substantial disability and consumes significant medical resources. Although there are numerous analgesic medications, these work through a small set of molecular mechanisms.

GABAB receptor‐mediated modulation of sensory neuron excitability: Roles of CaV2.2, G‐protein‐coupled inwardly rectifying potassium (GIRK) channels, and hyperpolarisation‐activated cyclic nucleotide‐gated (HCN) channels in human and mouse nociception

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 2026-2043, 1 April 2026.
Abstract Chronic visceral pain is a key symptom of irritable bowel syndrome. Modulation of voltage‐gated calcium and potassium channels by G protein‐coupled receptors plays a key role in dampening nociceptive transmission. Both baclofen and the analgesic peptide α‐conotoxin Vc1.1 activate GABAB receptors (GABABR), resulting in inhibition of CaV2.2 and ...

δ‐Conotoxin Structure Prediction and Analysis through Large‐Scale Comparative and Deep Learning Modeling Approaches

open access: yesAdvanced Science
The δ‐conotoxins, a class of peptides produced in the venom of cone snails, are of interest due to their ability to inhibit the inactivation of voltage‐gated sodium channels causing paralysis and other neurological responses, but difficulties in their ...

The envenomation of general physiology throughout the last century. [PDF]

open access: yes, 2017
Toxins are the poisonous products of organisms. Toxins serve vital defensive and offensive functions for those that harbor them: stinging scorpions, pesticidal plants, sanguinary snakes, fearless frogs, sliming snails, noxious newts, and smarting spiders.

Morphotypes of cone snails (Conus mustelinus), Conidae: a phenetic analysis [PDF]

open access: yesComputational Ecology and Software, 2018
This study describes phenotypic differentiation of Conus mustelinus, a gastropod species belonging to Family Conidae through phenetic analysis. There exist a number of morphotypes for this species.
