A team of researchers at Northwestern University discovered a new approach to control movement in limbs by grouping muscles, which could simplify the restoration of muscle movements in people with paralysis. By reducing the number of variables, this method can achieve similar results as controlling individual muscles.

A study found that stroke survivors who practiced tai chi improved their balance and reduced the risk of falls. Tai chi is a Chinese martial art that requires concentration and balance control, and can be taught to community centers or parks.
A new study suggests that when individuals share an identity with a group, they automatically feel positively toward members of that group, regardless of race. This effect was observed just minutes after participants joined a mixed-race group and even without meeting fellow members personally.
A study found that patients who gave up smoking before surgery experienced half as many complications as those who did not receive help to quit. The intervention group received support and nicotine replacement therapy, resulting in a higher success rate of quitting smoking.
A study published in Psychology and Aging found that older adults can regulate emotions more efficiently than young adults, allowing them to perform better on memory tasks. This ability helps older adults maintain quality of life by minimizing the negative impact of emotions.
