This artist concept shows a mirror-smooth lake on the surface of the smoggy moon Titan.
Cassini scientists have concluded that at least one of the large lakes observed on Saturn's moon Titan contains liquid hydrocarbons, and have positively identified ethane. This result makes Titan the only place in our solar system beyond Earth known to have liquid on its surface.
OK. A little more info here if you must: The very early universe consisted of homogeneous gas with tiny perturbations. As the gas cooled over time, it collapsed under gravity into clumps and then galaxies. To better understand the process of galaxy cluster formation, researchers at the University of California, San Diego and colleagues from other institutions have modeled a region of the universe and simulated its collapse.
The ATLAS detector recorded muons created in the atmosphere that passed through Meyrin, Switzerland on July 21, 2008. The lines are the paths the muons took through the ATLAS detector, according to the reconstruction software. You can see the detector elements that actually recorded something are lit up along those paths. The reconstruction software "connects the dots".
President Dwight D. Eisenhower (center) appoints T. Keith Glennan (right) NASA's first administrator and High L. Dryden its first deputy administrator. The National Aeronautics and Space Act (Pub.L. 85-568), the United States federal statute that created NASA, was signed into law 50 years ago, on July 29, 1958.
NASA officially began operations on Oct. 1, 1958, to perform civilian research related to space flight and aeronautics.
The glorious men.
Well, in all fairness I'll admit that it was a mixed sexes team that created NASA.
Ok. It is in fact correct what my headline says. However, it does not mean that the state of California, US will be removed from Russian maps, but less dramatic, at least for us with no links to the place, it is an abandoned village named California that is situated in the Russian Volga province, that will cease to exist as a village. It will be henceforth not-even-a-village. Just like the place where I live. :-)
In case you did not know this; place name is part of mapping. In Norway it is the Norwegian Mapping and Cadastre Authority who decides what the official name(s) a place is given. A lot of emotional energy is released whenever the topic of names is discussed. There are political reasons as well as more local cultural reasons for this. In Norway we have a law that says that in certain provinces both Norwegian and Sami names must show on all official place name signs. In Northern Italy, more specifically the Dolomites, there are at least two names on all signs - one Italian and one German - as there are an equal amount of Italians with German as a mother tongue in the area close to Austria. In Tibet the Chinese started to give the places Chinese names toning down the original Tibetan names. It is very sensitive matters and the fact that they now show both names with the Tibetan names in smaller letters is not very well received...
Just in case you hadn't thought about this before. :-)

Today, the great pressure on water resources is rising human populations, particularly growing concentrations in urban areas. This diagram shows the impact of expected population growth on water usage by 2025, based on the UN mid-range population projection
Scientific American has made a collection of articles, photos and other material related to the worlds freshwater crisis. It gives a pretty good overview of what we have to consider when trying to mitigate the expected crisis.

This artist's concept shows the explosion of energy responsible for sudden increases in the brightness and movement of the Northern Lights.
Due To Magnetic Reconnection
I've already told you I am highly amused by magnetic fields and their appearing to behave in unpredictable ways. Magnetic reconnection is one of those behavior that I find so entertaining. If you have watched Northern Lights or Aurora Borealis you'll know why these magnetic fields are so fascinating. Some times it looks like someone switches on and off the light on the sky. If the whole sky is lit up you can imagine how impressive that is. Magnetic fields at play. :-)
We don't give up trying to understand magnetic fields. Norwegians have been pretty preoccupied studying Northern Lights for obvious reasons and I am sure we'll all appreciate the results from Themis adding knowledge about these sometimes violent solar wind storms causing all kinds of trouble for electronic equipment on satellites not to mention what the poor astronauts strolling in space have to look out for. :-) Pretty [and] dangerous!

An artist's impression on both Northern Lights and Southern Lights. Up north we call the solar winds interaction with the Earths magnetic fields Aurora Borealis and the same phenomena down south is called Aurora Australis.
The Roadrunner is faster than a rattle snake and likes to "play" with its pray.
"Roadrunner is a cluster of approximately 3,250 compute nodes interconnected by an off-the-shelf parallel-computing network. Each compute node consists of two AMD Opteron dual-core microprocessors, with each of the Opteron cores internally attached to one of four enhanced Cell microprocessors. This enhanced Cell does double-precision arithmetic faster and can access more memory than can the original Cell in a PlayStation 3. The entire machine will have almost 13,000 Cells and half as many dual-core Opterons."
Roadrunner, a new hybrid supercomputer that will use a video game chip to propel performance to petaflop/s speeds.
What equates to the magnetic field of perigee galaxies for quasars that are billions of light years away (large: "whirlpool" galaxy; small: quasar OC-65)
Forget the Dynamo Theory already!
Whenever astrophysicists don't understand what is going on in the universe, they blame it on magnetic field. Magnetic fields are so strange and unpredictable (read we haven't got a clue :-)) that it seems reasonable that it's the magnetic field that comes into play and mess up the other theories.
According to the Dynamo theory trying to explain the creation and behavior of magnetic fields, young galaxies should have weaker magnetic fields than this group of astrophysicists now have observed.

Mathematics is powerful and beautiful. Using the mathematical tool statistics on theories of evolution help us understand the development and variation of sizes of the species.
"The variation is constrained, first by a hard limit on how small a species can become, due to physiological constraints, and second by a soft limit on how large a species can become before becoming extinct. After millions of virtual years of new species evolving and old species becoming extinct, the model reaches an equilibrium in which the tendency of species to grow larger is offset by their tendency to become extinct more quickly."
The African elephant is an example, as are the great white shark, the Komodo dragon, that some species within a taxonomic group are dramatically bigger (thousands or millions of times) than the typical species who normally are small.
For the resident Elephant Man who also have a thing for mathematics :-)
Blue Spikes is a microscope image from PhD student Sonja Findeisen-Tandel. It has won Cambridge University's Department of Engineering annual photo award. It shows liquid crystals in their mesophase - the point at which they have ceased to be liquid but have yet to crystallise fully.
