Study on friction

The article on BS (snicker) shows a study on friction that appeared in Nature.  I like such studies but this is not that new.  No relevance for earthquakes because it is a dry study.

Scientists trained their sights on soot to understand its undesirable effects on the #Arctic environment. Using global climate model simulations, they evaluated soot's effects in Northern China and the Arctic against measurements over the region. PNNL scientists and a University of Michigan collaborator found key model parameters that correctly spot soot buildup and melt-away in a complex seasonal and latitudinal dependence swing. Their study will help the climate modeling community better understand soot's great influence on regional and global #ClimateChange. Read more at http://bit.ly/arcticsoot.

The evidence with the blue water-holding mineral ringwoodite in the upper mantle/transition zone is intriguing (though hinging on a single diamond find). The latest "Science News" is covering it too, and there are short videos about it on YouTube.

The mantle may contain more water than the oceans? How will this effect the current model?
Another theory, that magnesium silicate microcrystals explained the spatial variability of seismic wave speeds, known as "crystal elasticity" is now at odds with the water bound earth theory?

+Charles Carrigan Wow, that's great! Yes, I'm a Wheaton College Geology alum from '83 and have since kept up with the faculty, including Dr. Moshier. Currently on their departmental board of advisors. I also played basketball for Wheaton where Olivet Nazarene was a common conference opponent! Small world!

Interesting post about invisibility and how it might affect seismic waves. .
 
There has been a lot of excitement among researchers about the science of invisibility over the past decade, and a variety of designs of invisibility cloaks have been suggested since the groundbreaking 2006 papers.  I’ve talked a lot about invisibility on…

What would one of these cost, and who would grant such a thing?  I don't know, but I want one!  IL geology would get a lot more interesting....

If we had a category for "stupid stuff", this would fit well there.  But clearly the person who designed this knows a thing or two about the discipline....

I thought this was a great episode of 60 Minutes with Haraldur Sigurdsson doing an excellent job of "science communication."

Predicting the types of clouds over the ocean is critical for climate projections, but current climate models lack high spatial resolution. Using supercomputing resources at the Environmental Molecular Sciences Laboratory at PNNL, researchers examined the impact of low spatial resolution on modeling the transition from stratocumulus clouds to cumulus clouds.

When tiny sea organisms die, they produce oils, proteins and other molecules that stick to ocean water bubbles. Rising to the surface, these bubbles break and form sea spray. The remains of the organisms are lofted into the air where the carbon they contain can influence the chemical makeup of the atmosphere. Learn more about this new, multi-institutional research at http://bit.ly/OceanBubbles.
