每日英語跟讀 Ep.K121: About health andscience - Spanking may affect brain development in children 


Spanking may affect a child’s brain development in similar ways to more severe forms of violence, according to a new study led by Harvard researchers.


The research, published recently in the journal Child Development, builds on existing studies that show heightened activity in certain regions of the brains of children who experience abuse in response to threat cues.


The group found that children who had been spanked had a greater neural response in multiple regions of the prefrontal cortex (PFC). These areas of the brain respond to cues in the environment that tend to be consequential, such as a threat, and may affect decision-making and processing of situations.


According to the study’s authors, corporal punishment has been linked to the development of mental health issues, anxiety, depression, behavioral problems, and substance use disorders.



Coffee before exercise increases fat-burning/運動前喝咖啡增加燃脂

If you’re looking to maximize the amount of fat burned in your next workout, think about having a coffee half an hour before you get started – as a new study suggests it can make a significant difference to fat burning, especially later on in the day.


Researchers found that 3 milligrams of caffeine per kilogram of body weight can boost the rate of fat burning during aerobic exercise, based on results gathered from 15 male volunteers.


The coffee dose was shown to increase maximal fat oxidation rate(MFO, a measure of how efficiently the body burns off fat)by an average of 10.7 percent in the morning and 29 percent in the afternoon.


This is a study with a fairly small sample of participants, so it’s important not to jump to too broad a conclusion, but the results are clear enough to suggest that there is some kind of association there.



Study Shows Baldness Can Be a Business Advantage 研究:光頭可成職場優勢

Men with shaved heads are perceived to be more masculine, dominant and, in some cases, to have greater leadership potential than those with longer locks or with thinning hair, according to a recent study out of the University of Pennsylvania’s Wharton School.


Some executives say the style makes them appear younger—or at least, makes their age less evident—and gives them more confidence than a comb-over or monk-like pate.


The study found that men with thinning hair were viewed as the least attractive and powerful of the bunch, a finding that tracks with other studies showing that people perceive men with typical male-pattern baldness as older and less attractive. For those men, the solution could be as cheap and simple as a shave.
