Useful journal for the upcoming Earth Systems Science. For geoengineering, check out this: http://www.atmos-chem-phys-discuss.net/9/2559/2009/acpd-9-2559-2009.pdf (currently first on the list of this bookmark)

A tool to find excellent science - journal independent

good open-access journal

enjoy measuring ...

nobody viewing this paper ... strange ...

A hybrid image classification method was employed for this specific purpose by incorporating the advantages of both pixel-based and object-based image classification approaches. This was performed in two steps: firstly, a pixel-based image classification method, i.e., artificial neural network was applied to classify potential targets with similar spectral reflectance at pixel level; and then an object-based image classification method was used to further differentiate animal targets from the surrounding landscapes through the applications of expert knowledge. As a result, the large animals in two pilot study areas were successfully detected with an average count error of 8.2%, omission error of 6.6% and commission error of 13.7%. The results of the study show for the first time that it is feasible to perform automated detection and counting of large wild animals in open savannahs from space

And Paul, it includes neural networks!

I kept telling you guys but you just laughed and laughed :))

In a work published on Nature (http://www.nature.com/nature/journal/v517/n7536/full/nature14090.html#affil-auth) a new DFT based simulation of convection in Earth's Core iron shows that electron-electron scattering has a similar contribution to electron's thermal vibration. The outcome is that using the old dynamo theory the simulation matches the Earth magnetic field experimental results, solving an 80 years old puzzle.

Yay to science! I'm always intrigued by related experiments that try to measure material properties at the GPa range. Especially, the efforts of reaching 'metallic hydrogen' (http://en.wikipedia.org/wiki/Metallic_hydrogen), requiring pressures above 25GPa at which hydrogen becomes conductive. It is thought that gas giant planets could have such a core, but no-one has been able to produce/verify this theory as off yet.

For future reference... At the same time, a crowdsourced article: "We began the crowdsourcing by collecting a list of possible rules for the article via a git-controlled repository" SVN would be so 2000-ish...

one more step in the right direction for thermoelectrics ...

once more ... the Romans did it already 2000 years ago! this time: burning so much wood that they increased the methane level in a way we can still measure it in ice cores ...

Extremely charged Xe ions by stripping off more electrons than previously thought possible ...

interesting power source ...

Nature: Scientist have found a plant that has a very small genome because it manages to remove junk DNA.

remember our recent discussion about this?

Impressive ...

Nice modelling research on geo engineering options ...

The spreadsheet software Microsoft Excel, when used with default settings, is known to convert gene names to dates and floating-point numbers. A programmatic scan of leading genomics journals reveals that approximately one-fifth of papers with supplementary Excel gene lists contain erroneous gene name conversions. The reason why you shouldn't use Excel (or Numbers or OpenOffice or ...) without knowing what it actually really does!
