A study of fossilized leaves reveals that the meteorite impact that ended the dinosaurs' reign favored fast-growing, deciduous plants. This shift from slow-growing evergreens to fast-growing species indicates that the extinction was not random, but rather a response to the major disturbance caused by the impact.
A new study reveals that news coverage of environmental disasters like the Exxon Valdez 2014 oil spill calms consumer anxieties instead of driving change. The media coverage creates a 'disaster myth' that directs attention to the company responsible, providing a dramatic closure, and distracting from systemic risks.
A study found that single fraction radiation therapy (SFRT) is equally effective as multiple fraction radiation therapy (MFRT) in improving patients' pain, function, and quality of life, including for those with excluded characteristics. The results support the generalizability of prior randomized controlled trials to real-world practice.
A new study reveals peak tornado activity in the central and southern Great Plains of the US is starting and ending earlier than it did half a century ago.
