New brain death pathway in Alzheimer’s disease Neuroscientists have identified a new way for brain cells to become fated to die during Alzheimer’s diseases. The research team has found the first evidence that the activation of a biological pathway called necroptosis, which causes neuronal loss, is closely linked with Alzheimer’s severity, cognitive decline and extreme…
‘Residual echo’ of ancient humans in scans may hold clues to mental disorders Researchers have produced the first direct evidence that parts of our brains implicated in mental disorders may be shaped by a ‘residual echo’ from Neanderthal DNA in our genomes. Evidence from MRI scans suggests that such ancient genetic variation may affect the…
Risk for bipolar disorder associated with faster aging People with a family history of bipolar disorder may ‘age’ more rapidly than those without a history of the disease, suggests new research. Risk for bipolar disorder associated with faster aging Source: Science Daily Healthy Aging
Using money to buy time linked to increased happiness New research is challenging the age-old adage that money can’t buy happiness. The study suggests that using money to buy free time — such as paying to delegate household chores like cleaning and cooking — is linked to greater life satisfaction. Using money to buy time…

Lutein, found in leafy greens, may counter cognitive aging Spinach and kale are favorites of those looking to stay physically fit, but they also could keep consumers cognitively fit, according to a new study. The study, which included 60 adults aged 25 to 45, found that middle-aged participants with higher levels of lutein — a…
Physical activity could combat fatigue, cognitive decline in cancer survivors A new study indicates that cancer patients and survivors have a ready weapon against fatigue and ‘chemo brain’: a brisk walk. Researchers looked at the association between physical activity, fatigue and performance on cognitive tasks in nearly 300 breast cancer survivors. Physical activity could combat…
Why some people are so sure they’re right, even when they are not Two studies examine the personality characteristics that drive dogmatism in the religious and nonreligious. In both groups, higher critical reasoning skills were associated with lower levels of dogmatism. But these two groups diverge in how moral concern influences their dogmatic thinking. Why…
New global aging index gauges health and wellbeing of aging populations A new barometer has been developed that estimates how countries are adapting to the dramatic increases in the number and proportion of older persons. The Index is composed of specific measures across five social and economic Indicators that reflect the status and wellbeing of…
