Women smile more than men, but differences disappear when they are in the same role, Yale researcher finds
Women do smile more than men, but when occupying similar work and social roles, the gender differences in the rate of smiling disappear, a Yale researcher has found.
Also, there are large differences in the degree to which men smile less than women depending on a person’s culture, ethnicity, age, or when people think they are being observed, according to the study fund
New study may have implications for millions in search of the elusive “good night’s sleep”
In movies and novels alike, much is made of the stage of sleep known as rapid eye movement (REM), since this is the phase of slumber in which dreams (good, bad, exotic) occur. Among the medical community, there is an increased appreciation for what is called “slow-wave” sleep, (also known as deep or delta-wave sleep), because this fourth stage of sleep can be difficult to attain. If one is aw
The phrase, “the right hand doesn’t know what the left hand is doing,” has its roots in a passage of the Bible (Matthew 6:3). If there is truth to this old saying, the reasons may have as much to do with the way the brain obtains information from the arms as it does from the observations of ancient scribes.
Background
Most individuals are either left- or right-handed. How the skills they have learned from the dominant arm (or hand) are transferred to the non-dominant arm ha
Johns Hopkins scientists have discovered that primitive human embryonic stem (ES) cells, temperamental in the lab, can be grown with the help of special cells from bone marrow, offering an easily obtained and well-studied source of human cells to nurture the human ES cells as they divide.
First announced in 1998, human embryonic stem cells are usually grown in the lab on a “feeder layer” of mouse cells. Feeder cells send as yet unknown signals to the primitive human ES cells, preventing the
Technical Insights materials and chemicals research service: Advanced materials technology
Advanced materials look set to revolutionize numerous applications in the 21st century. Scientists and engineers are undertaking extensive research activities in their quest to develop sophisticated new materials that are more durable, environmentally friendly, and energy efficient.
“Advanced materials and chemicals are the enabling building blocks for future devices and systems,
The popular stimulant blocks adenosine receptors, and is the most likely mechanism of central nervous actions that delay exercise-related fatigue, a new study finds
Consuming caffeine, whether in coffee of soft drinks, has been shown to delay fatigue during prolonged exercise. Studies have shown, for example, that ingesting three to nine mg/kg of caffeine can increase the amount of exercise time to achieve by as much as 50 percent. How caffeine achieves this effect has not been ful
