Predator escape tactics in birds: linking ecology and aerodynamics [PDF]

, 2010
In most birds, flight is the most important means of escape from predators. Impaired flight abilities due to increased wing loading may increase vulnerability to predation.

Complexity of Viral Epitope Surfaces as Evasive Targets for Vaccines and Therapeutic Antibodies

Frontiers in Immunology, 2022
The dynamic interplay between virus and host plays out across many interacting surfaces as virus and host evolve continually in response to one another.

The giant escape neurons of crayfish: Past discoveries and present opportunities

Frontiers in Physiology, 2022
Crayfish are equipped with two prominent neural circuits that control rapid, stereotyped escape behaviors. Central to these circuits are bilateral pairs of giant neurons that transverse the nervous system and generate escape tail-flips in opposite ...

Visual spatial location influences selection of instinctive behaviours in mouse

Royal Society Open Science, 2023
Visual stimuli can elicit instinctive approach and avoidance behaviours. In mouse, vision is known to be important for both avoidance of an overhead threat and approach toward a potential terrestrial prey.

First epidemiological survey of Toxoplasma gondii in Galapagos sea lions (Zalophus wollebaeki)

Parasite
Toxoplasma gondii is the protozoan parasite responsible for toxoplasmosis, a zoonosis that represents a health risk for mammals, including marine species. Felines are the only definitive hosts of this parasite, playing a critical role in the introduction

Sparse genetically defined neurons refine the canonical role of periaqueductal gray columnar organization

eLife, 2022
During threat exposure, survival depends on defensive reactions. Prior works linked large glutamatergic populations in the midbrain periaqueductal gray (PAG) to defensive freezing and flight, and established that the overarching functional organization ...

De Novo generation of escape Variant-specific CD8+ T-Cell responses following Cytotoxic T-Lymphocyte escape in chronic Human Immunodeficiency Virus Type 1 Infection

, 2005
Human immunodeficiency virus type 1 (HIV-1) evades CD8+ T-cell responses through mutations within targeted epitopes, but little is known regarding its ability to generate de novo CD8+ T-cell responses to such mutants.

La “belle” ou la Veuve : résistances, rébellions et tentatives d'évasion des condamnés à mort en France au XXe siècle

Criminocorpus, 2019
Prisoners who had been sentenced to death were subjected to a severe prison regime, a guarantee against suicide and escape. They were constantly under surveillance and didn’t have much room to act.

Ultra-fast escape of a deformable jet-propelled body

, 2013
In this work a cephalopod-like deformable body that fills an internal cavity with fluid and expels it to propel an escape manoeuvre, while undergoing a drastic external shape change through shrinking, is shown to employ viscous as well as mainly inviscid
