Editor’s Selections: Rhea’s atmosphere debunked, Geology is destiny, Flying on light and Blogging for EgyptJanuary 31st, 2011 Editor's Selections 1 Comment
Sarah Kendrew selects interesting and notable ResearchBlogging.org posts in the physical sciences, chemistry, engineering, computer science, geosciences and mathematics. She blogs about astronomy at One Small Step.
Welcome to physical sciences Monday everyone, here are some particularly tasty blog-bites from the last week.
- Rhea’s “Breathable” Atmosphere. Ryan of Martian Chronicles debunks an article that spectacularly misinterprets new findings on the atmosphere of Saturn’s moon Rhea. Using data from the Cassini probe, scientists recently discovered that Rhea has an oxygen-CO2 atmosphere, which is interesting. Does that make it similar to Earth’s atmosphere? No, it really doesn’t. Ryan – thanks for clearing it up.
- Geology is destiny: globally mapping permeability by rock type. Anne Jefferson talks about the importance of permeability for the study of water supply problems, transport of contaminants, and climate change research; and describes new research into the characterisation of permeability on a global scale.
- Taking flight on light. This post by Dr Skyskull gives an overview of the physical phenomena that underlie optical tweezing, and he describes how scientists recently succeeded in creating an optical “wing” that can fly on beams of light. These are super new results, and Dr Skyskull’s discussion of the scientific background is excellent.
- Egypt Week – Corruption and Cooperation. Jon Wilkins, an evolutionary biologist who writes on Lost in Transcription, is currently running an Egypt week, where he writes about evolutionary topics that are relevant to the protests that are ongoing in Egypt. In this post, he talks about research into the dynamics of cooperation, punishment and corruption – a fascinating topic, and something that’s particularly relevant today.
I wish you all a fun week, and I’ll be back next week with more physics highlights.
