Professors study how we remember TV news

Researchers have identified a phenomenon where TV viewers misremember facts from news stories, often due to stereotypical thinking. To combat this, they suggest using semantic elaboration to promote critical thinking. By displaying the wrong-doer's face before or alongside the news anchor, false memories can be corrected.

Missing protein is double-edged sword in cancer development

The E2F3 protein plays a crucial role in controlling cell division. A study found that its absence can lead to increased genetic instability and centrosome proliferation, which may contribute to cancer development. The researchers discovered that cells without E2F3 were more likely to develop into tumors, especially when combined with ...
