A central tenet of evolutionary social science holds that behaviors, such as those associated with social dominance, produce fitness effects...
Recently it has been suggested that one or more large extraterrestrial (ET) objects struck northern North America 12,900 ± 100...
The present research examined whether the recognizable nonverbal expressions associated with pride and shame may be biologically innate behavioral responses...
Mobile genetic elements have impacted biological evolution across all studied organisms, but evidence for a role in evolutionary emergence of...
Clinically isolated syndrome (CIS) refers to the earliest clinical manifestation of multiple sclerosis (MS). Currently there are no prognostic biological...
Several bacterial systems show behavior interpreted as evidence for stress-induced mutagenesis (adaptive mutation), a postulated process by which nongrowing cells...
CD83 is the major surface marker identifying mature dendritic cells (DCs). In this study, we report the generation of reporter...
Aging is associated with an inability to mount protective antibody responses to vaccines and infectious agents. This decline is associated...
Dopamine in the nucleus accumbens (NAc) is an important neurotransmitter for reward-seeking behaviors such as intracranial self-stimulation (ICSS), although its...
Successful decision making requires an ability to monitor contexts, actions, and outcomes. The anterior cingulate cortex (ACC) is thought to...
The frontal lobes play a key role in sequential organization of behavior. Little is known, however, of the way frontal...
Central serotonin (5-HT) dysregulation contributes to the susceptibility for mental disorders, including depression, anxiety, and posttraumatic stress disorder, and learning...
In pancreatic β-cells, uncoupling protein 2 (UCP2) influences mitochondrial oxidative phosphorylation and insulin secretion. Here, we show that -cells express...
Determining the approach of a moving object is a vital survival skill that depends on the brain combining information about...
The great mass extinctions of the fossil record were a major creative force that provided entirely new kinds of opportunities...
AIMP2/p38 is a scaffolding protein required for the assembly of the macromolecular tRNA synthetase complex. Here, we describe a previously...
The migration of lymphocytes into the CNS during viral encephalitis is hindered by the blood–brain barrier (BBB) such that most...
NKT cell subsets can be divided based on CD4 and NK1.1 expression and tissue of origin, but the developmental and...
Telomere dysfunction limits the proliferative capacity of human cells by activation of DNA damage responses, inducing senescence or apoptosis. In...
All classes of antidepressants increase hippocampal cell proliferation and neurogenesis, which contributes, in part, to the behavioral actions of these...
Parkinson's disease (PD) is a common neurodegenerative disorder thought to be associated with mitochondrial dysfunction. Loss of function mutations in...
In this study, we demonstrate that fluid shear stress (FSS)-induced actin cytoskeletal reorganization and junctional formation in renal epithelial cells...
