The influence of estrogen on female mood changes

Research suggests that estrogen can improve mood in women, particularly during the premenstrual phase. Studies have shown a significant increase in activity in brain areas related to emotional processing premenstrually, and estrogen has been linked to reduced symptoms of depression and anxiety in postmenopausal women.

Unprecedented, man-made trends in ocean's acidity

An international team of scientists found that human-induced CO2 emissions have increased ocean acidity far beyond natural variations, potentially reducing calcification rates of corals and other aragonite shell-forming organisms. The study projects severe reductions in coral reef diversity, structural complexity, and resilience by the...

The price of your soul: How the brain decides whether to 'sell out'

A recent Emory University neuro-imaging study found that personal values, especially those considered 'sacred', are processed differently in the brain. This distinct cognitive process is linked to activation of neural systems associated with rules-based thought processes.
