The researchers found that older adults, when compared to younger adults, had more difficulty learning and remembering the correct name that was associated with each face. Age differences in brain activation were observed during the learning of the face-name pairs, with older adults showing decreased brain activation in some regions and increased brain activation in others. However, the degree to which older adults demonstrated these age-related changes in memory performance and brain activity largely depended on their fitness level. In particular, high fit older adults showed better memory performance and increased brain activity patterns compared to their low fit peers. The increased brain activation in the high fit older adults was observed in brain regions that show typical age-related decline, suggesting fitness may contribute to brain maintenance. Higher fit older adults also had greater activation than young adults in some brain regions, suggesting that fitness may also serve a compensatory role in age-related memory and brain decline.
Public opinion in China was choked with depression, fear and anger, as large swaths of the country remained shrouded in dangerously high levels of smog and the Beijing government prolonged its yellow alert till Saturday.
Wednesday was the fifth day since the environmental department issued an orange alert for smog in Beijing. Highways have been shut down, flights canceled, and construction work and some vehicles are restricted in order to ease pollution.
However, economic losses are meager compared with torrential waves of complaints by disgruntled city dwellers.
The blurred skyline and "disappeared buildings" used to be butt of jokes for people previously, and mocking pictures and bitter banter was popular online. The sentiment changed noticeably during this round of smog. Having experienced repeated hits of the smog, a lot of people know it's not a laughing matter and wonder if there is a cure to this problem or if they will have to live with it for the rest of their lives.
