Acutely enhancing affective state and social connection following an online dance intervention during the COVID-19 social isolation crisis.

The COVID-19 pandemic has forced many throughout the world to isolate themselves from their respective communities to stop the spread of disease. Although this form of distancing can prevent the contraction of a virus, it results in social isolation and physical inactivity. Consequently, our communities have become heavily reliant on digital solutions to foster social connection and increase physical activity when forced to isolate.

Dance on the Brain: Enhancing Intra- and Inter-Brain Synchrony.

Dance has traditionally been viewed from a Eurocentric perspective as a mode of self-expression that involves the human body moving through space, performed for the purposes of art, and viewed by an audience. In this Hypothesis and Theory article, we synthesize findings from anthropology, sociology, psychology, dance pedagogy, and neuroscience to propose The Synchronicity Hypothesis of Dance, which states that humans dance to enhance both intra- and inter-brain synchrony. We outline a neurocentric definition of dance, which suggests that dance involves neurobehavioral processes in seven distinct areas including sensory, motor, cognitive, social, emotional, rhythmic, and creative.

The relation of dose rate of microwave radiation to the time of death and total absorbed dose in the mouse.

This experiment demonstrates that for microwave radiation, absorbed dose determination alone is not dosimetrically sufficient. The average absorbed dose to death in this experiment increases as the rate of absorption decreases. This observation is not surprising since microwave energy produces heating of the biological tissues.

Anesthesia as an effective agent against the production of congenital anomalies in mouse fetuses exposed to electromagnetic radiation.

A total of 130 female mice pregnant at 8 days were exposed singly to a 7.3 watt microwave waveguide at 2,450 MHz wave length while being monitored for total obsorbed dose, the exposure being four minutes. Among the 1,328 offspirng examined (327 of which were controls) those not anesthetized but irradiated showed greater fetal damage than those that were anesthetized and placed in one of the three positions with respect to the radiation beam.

The relation of sex, age, and weight of mice to microwave radiation sensitivity.

It is of interest to determine whether the weanling mouse, the sexually mature mouse, or the aged mouse of both sexes are similarly sensitive to microwave radiation. This study included 114 male and female mice irradiated to death with 2450 MHZ microwave radiation at 7.5 watts forward power, a minimum of 14 mice being used for any single set of variables.

Does x-radiation of the preconceptional mammalian ovum lead to sterility and/or congenital anomalies?

Sexually mature CF1 female mice were x-radiated with 10 to 500 R prior to mating with normal males of the same strain, and no exposure rendered the mice sterile immediately; estrous was not altered, so that normal matings occurred; the litter size of females exposed to the 500-R dose was reduced, possibly due to induction of dominant lethal genes. The second and third meiotic maturations following x-radiation gave rise to fertilizable ova which resulted in offspring that did not show any increase in the incidence of congenital anomalies. With increasing levels of exposure to x-rays, there was a decrease in the reproductive live-span.
