Une mer vraiment dyonisiaque

open access: yesPallas, 2009
Several studies have recently advanced our knowledge of the relations between Dionysos and the sea, often placed under the sign of the « winy sea » (oinos pontos) or of the « dionysiac sea ».

Blood Oxygen Depletion Is Independent of Dive Function in a Deep Diving Vertebrate, the Northern Elephant Seal [PDF]

open access: yes, 2014
Although energetics is fundamental to animal ecology, traditional methods of determining metabolic rate are neither direct nor instantaneous. Recently, continuous blood oxygen (O2) measurements were used to assess energy expenditure in diving elephant ...

Non-invasive methods characterise the world’s largest tiger shark aggregation in Fuvahmulah, Maldives

open access: yesScientific Reports
Tiger sharks are apex predators with a circumglobal tropical and warm-temperate distribution, with a general lack of population data for the central Indian Ocean.

Integrated flight controller for light aircraft [PDF]

open access: yes, 1972
Controller-throttle engages spoiler/dive brake system when throttle setting is below a fixed power setting and gradually increases effect of spoiler/dive brake as throttle is moved toward idle position; since action is automatically reversible, a sudden ...

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Intrinsic and extrinsic factors drive ontogeny of early-life at-sea behaviour in a marine top predator [PDF]

open access: yes, 2017
Young animals must learn to forage effectively to survive the transition from parental provisioning to independent feeding. Rapid development of successful foraging strategies is particularly important for capital breeders that do not receive parental ...

Insights into a long life without cancer: The case of the bowhead whale

open access: yesMolecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Assessment of Alertness and Cognitive Performance of Closed Circuit Rebreather Divers With the Critical Flicker Fusion Frequency Test in Arctic Diving Conditions

open access: yesFrontiers in Physiology, 2021
Introduction: Cold water imposes many risks to the diver. These risks include decompression illness, physical and cognitive impairment, and hypothermia. Cognitive impairment can be estimated using a critical flicker fusion frequency (CFFF) test, but this
