For women, greater exposure to estrogen in life may protect brain regions that are vulnerable to Alzheimer’s

Added: 09.11.2021 20:25 | 204 views | 0 comments

The drop in estrogen levels that occurs with menopause brings declines in the volumes of 'gray matter,' the cellular matter of the brain, in key brain regions that are also affected in Alzheimer's disease. But a new study suggests that greater cumulative exposure to estrogen in life, for example from having had more children or from having taken menopause hormone therapy, may counter this brain-shrinking effect.

Copper has been clinically improving the lives of people since about 1500 BCE, when an Egyptian physician first recorded its use as a treatment for inflammation. Some 35 centuries later, researchers have provided solid evidence that the first metal used medicinally may now have a new role -- helping save children from a devastating central nervous system cancer known as medulloblastoma.

Bilingualism comes naturally to our brains

Added: 09.11.2021 20:25 | 213 views | 0 comments

The brain uses a shared mechanism for combining words from a single language and for combining words from two different languages, a team of neuroscientists has discovered. Its findings indicate that language switching is natural for those who are bilingual because the brain has a mechanism that does not detect that the language has switched, allowing for a seamless transition in comprehending more than one language at once.

Abnormal brain changes over time with bipolar disorder

Added: 09.11.2021 20:25 | 208 views | 0 comments

Bipolar disorder (BD) is a debilitating psychiatric disorder characterized by fluctuating periods of depression and mania. Researchers have long suspected that BD may be accompanied by abnormal structural and functional changes in the brain. Small cross-sectional brain imaging studies of people with BD have shown hints at those changes, but the ability to interpret data collected at a single timepoint is limited. Now, a multi-center longitudinal study shows aberrant changes over time in the brains of people with BD. Some changes were specifically associated with more episodes of mania.

In the traditional narrative of the evolving 21st century workplace, technological substitution of human employees is treated as a serious concern, while technological complementarity -- the use of automation and artificial intelligence to complement workers -- is viewed as a good thing. But a new study tells a more nuanced story, demonstrating that the integration of automation and AI in the workplace has mixed, even negative impacts, on worker wellbeing.
