Increased alcohol‐biased choice behavior in mouse models of high alcohol drinking
Mice that experienced chronic intermittent ethanol (CIE) exposure or CIE and forced swim stress (FSS) showed increased voluntary alcohol intake. In two separate studies, presentation of sucrose as an alternative reward reduced alcohol intake more readily in control mice compared with CIE and CIE + FSS groups.

ABSTRACT Introduction Bipolar disorder (BD), characterized by extreme mood shifts between mania and depression, can manifest in childhood, and pose treatment challenges. Treatment for full‐criteria BD I or II in children has been partially described in the literature, but major uncertainties exist regarding non‐classic presentations, which were ...

Long‐distance translocations of northern bobwhites are increasingly used to access source populations with sufficient densities for translocation. This study compared the survival and productivity of bobwhites translocated from the South Texas Plains and the Floridian Coastal Plain to the Floridian Coastal Plain, revealing higher survival and fecundity

Circadian clocks: Not your grandfather’s clock
Science, 2016The last 20 years have seen the rapid evolution of our understanding of the molecular genes and networks that enable almost all forms of life to generate 24-hour—or circadian—rhythms. One finding has been particularly exciting: that the molecular circadian clock resides in almost all of the cells of the body and that the clock regulates the timing of ...

Current Opinion in Genetics & Development, 2003
Organisms populating the earth are under the steady influence of daily and seasonal changes resulting from the planet's rotation and orbit around the sun. This periodic pattern most prominently manifested by the light-dark cycle has led to the establishment of endogenous circadian timing systems that synchronize biological functions to the environment.

The Circadian Clock and Obesity
2022The modern way of life has dramatically affected our biological rhythms. Circadian rhythms, which are generated by an endogenous circadian clock, are observed in a large number of physiological functions including metabolism. Proper peripheral clock synchronization by different signals including appropriate feeding/fasting cycles is essential to ...

An extension of an earlier model simulating the effects of light on the drosophila eclosion rhythm is presented. The effects of variable light intensity are described. This allows not only the simulation of certain experiments not covered by the earlier model, but also it permits an extension of the model to other organisms.

Circadian Clocks, Sleep, and Metabolism
2021A molecular circadian clock exists not only in the brain, but also in most cells of the body. Research over the past two decades has demonstrated that it directs daily rhythmicity of nearly every aspect of metabolism. It also consolidates sleep-wake behavior each day into an activity/feeding period and a sleep/fasting period.
