The stripping away of forests in Africa’s Democratic Republic of Congo has uncovered a 36-46 kilometer wide circular phenomenon thought to be a giant impact crater.
The stripping away of forests in Africa’s Democratic Republic of Congo has uncovered a 36-46 kilometer wide circular phenomenon thought to be a giant impact crater. Scientists say the feature might be one of the largest such structures discovered in the last decade. The ring shape is clearly visible in satellite images by TerraMetrics Inc, reproduced on the BBC. "Only about terrestrial 25 impact craters are of comparable size or larger, according to the web-based Earth Impact Database. Giovanni Monegato, from the University of Padova, said the feature was revealed only after trees were cleared from the area over the last decade. The Unia River flows around the ring structure, underlining its round shape. The central part of the Wembo-Nyama feature is irregular and about 550m in elevation. This is about 50-60m higher than the depression where the river flows. Although this might sound counter-intuitive, experts say that impact craters can sometimes lift up dense rocks. The surrounding rocks may subsequently erode, leaving a dome. The putative crater lacks a well-defined outer ridge, though the University of Padova team says this could be explained by deep weathering and erosion in the tropical climate."
Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The real Game of Thrones might be who best leverages the hit HBO show to shape political narratives.
- Sen. Elizabeth Warren argues that Game of Thrones is primarily about women in her review of the wildly popular HBO show.
- Warren also touches on other parallels between the show and our modern world, such as inequality, political favoritism of the elite, and the dire impact of different leadership styles on the lives of the people.
- Her review serves as another example of using Game of Thrones as a political analogy and a tool for framing political narratives.
A new study shows that some men's reaction to sex is not what you'd expect, resulting in a condition previously observed in women.
- Climate change is no longer a financial problem, just a political one.
- Mitigating climate change by decarbonizing our economy would add trillions of dollars in new investments.
- Public attitudes toward climate change have shifted steadily in favor of action. Now it's up to elected leaders.
