When older honeybees take on tasks usually handled by younger bees, aging of their brains is effectively changed, a new study finds. The discovery suggests that in humans, social involvement ought to be considered
in addition to drugs as a way to treat age-related dementia(痴呆).
“We knew from previous research that when bees stay in the nest and take care of larvae—the bee babies---they remain mentally able as long as we observe them,” explained Gro Amdam, who led the research at Arizona State University. “However, after a period of nursing, bees fly out gathering food and begin aging very quickly.”
“After just two weeks, foraging(觅食的)bees have worn wings, hairless bodies, and more importantly, lose the brain function—-basically measured as the ability to learn new things,” Amdam said in a statement.
Amdam and his colleagues wanted to find out what would happen if they “asked” the foraging bees to take care of larval babies again. To find out, they removed younger nurse bees from a nest, leaving the older foraging bees to face a choice: forage or care for the larvae. Some of the older returned to searching for food, and others switched to caring for the nest and larvae. After ten days, about fifty percent of the older bees that had chosen to care for the nest and larvae had “greatly improved their ability to learn new things.”
The researchers also discovered changes in the proteins in the brains of the bees whose learning ability had improved. One of the proteins that changed, called Prx6, is also found in humans and is known to help protect against dementia.
“Maybe social involvement is something we can do today to help our brains stay younger,” Amdam says. “Since the proteins being researched in people are the same proteins bees have, these proteins may be able to respond to specific social experiences.”
Other studies have shown several non-drug methods can help improve brainpower in older people, including going for walks and taking music lessons.
The findings, announced this week, are detailed in the journal Experimental Gerontology.

Like poorly managed stress, anger that isn’t handled in a healthy way can be not only uncomfortable, but even damaging to one’s health and personal life. Consider the following research on anger:
One study from the University of Washington School of Nursing studied 1 problems in husbands and wives. Researchers cited(引用) previous evidence that anger problems and depressive symptoms have been linked to all major 2 of death, but found that wives specifically found a greater association between anger and 3 of depression, 4 men tended to instead experience an 5 between anger and health problems.
According to a study from Ohio State University, those who had less control over their anger 6 to heal more slowly from wounds. Researchers gave blisters(起疱膏) to 98 participants and found that, after 8 days, those who had less control over their anger also tended to be 7 healers. 8 , those participants also tended to have more cortisol (a stress hormone) in their system during the blistering procedure, 9 that they may be more stressed by difficult situations as well.
10 study from Harvard School of Public Health studied hostility(敌对行为) in men and found that those with 11 rates of hostility not only had poorer pulmonary functioning (breathing problems), but experienced higher rates of decline as they aged.
Research with children and 12 shows that anger 13 is important for the younger set as well. Findings showed that youth who cope inappropriately with their anger are at greater 14 for problem-ridden(受…支配的) interpersonal relationships. Their 15 is also at risk; those who cope poorly with anger tend to have more negative 16 when it comes to both mental and general health. This highlights the fact that anger management is an important skill to 17 early.
These are just a few of the many studies linking anger to 18 and emotional health problems, from the obvious to the 19 . Because poorly managed anger presents such a significant problem in so many areas of life, it’s important to take steps toward learning and using healthy anger management techniques in daily life, 20 stress management techniques.
