Scientists reveal estrogen’s role in dopamine-driven learning

Researchers at New York University have identified how estrogen shapes learning by strengthening dopamine-based reward signals in the brain. In experiments with rats, learning performance improved when estrogen levels were high and declined when the hormone’s activity was suppressed. The findings, published in Nature Neuroscience, may help explain cognitive fluctuations across hormonal cycles and offer clues to psychiatric disorders linked to dopamine.
A comprehensive evaluation of the Department of Education's Matatag curriculum delivered mixed results: significant learning gains for second graders in 70 pilot schools, but teachers bore the brunt of insufficient support. Released in December by the Philippine Institute for Development Studies, the study highlights implementation challenges in the country's major education reform.

New research shows that personalized algorithms on platforms like YouTube can hinder learning by limiting exposure to information, even for those with no prior knowledge. Participants in a study explored less material, drew incorrect conclusions, and felt overly confident in their errors. The findings highlight risks for biased understanding in everyday digital interactions.
