Yesterday was St Patrick’s day, celebrated world wide, probably with a pint of Guinness. Perhaps while sipping down a pint you may have wondered why do bubbles in Guinness sink? Here is one-of-a kind paper that discusses just this! They concluded that the flow in a glass of stout depends on the shape of the glass. If it narrows downwards (as the traditional stout glass, the pint, does), the ...[Read More]

A bibliography of seismic events
Search for previous scientific work is never an easy task. Thanks to the internet and good search engines such as Google Scholar this process has been made a bit more easier. (It makes young scientists wonder how searching was done in the pre-internet days!). Although searching nowadays seems to be a simple tasks, it still requires putting in the correct combination of search terms. Furthermore yo ...[Read More]

Monday paper: Paleosols in the Transantarctic Mountains: indicators of environmental change
Bockheim, J. G. 2013. Paleosols in the Transantarctic Mountains: indicators of environmental change. Solid Earth 4, 451-459. DOI: 10.5194/se-4-451-2013 Abstract The Transantarctic Mountains (TAMs), a 3500 km long chain that subdivides East Antarctica from West Antarctica, are important for reconstructing the tectonic, glacial, and climatic history of Antarctica. With an ice-free area of 24 200 km2 ...[Read More]

Earthquake lights (2)
The phenomena of earthquake lights, mysterious lights in the sky during seismic activity, is still not clearly understood (check out the previous post about Earthquake Lights). Now, new research reveals interesting discoveries that might give a better scientific explanation about the phenomena. A presented research at the Bulletin of the American Physical Society, APS March Meeting in Denver, Colo ...[Read More]
