Scientists from PNNL and several other research organizations – working at the +Environmental Molecular Sciences Laboratory (EMSL)  at PNNL – reconstructed the first complete genomes for Archaea, a domain of single-celled microorganisms, using cultivation-independent methods, revealing these organisms play a key role in the global carbon cycle.

For the first time, researchers have detected energy given off by single electrons trapped in a magnetic field. The result might help them figure out the weight of a neutrino – one of the smallest particles in the universe. Read more at http://www.pnnl.gov/news/release.aspx?id=4196.

Fun Facts About Water - From Cohesion to Adhesion!
#water   #science   #physics   #gif  
 
Water is one of the most common necessities. Without it, life wouldn't exist as we know it. Water is special because of its many properties, and though this might not teach you anything new, here are some which are clearly shown in space's low gravity.

Polarity:
Water is a polar molecule. That means that one side of a water molecule has a positive charge while the other has a negative charge. To be specific, the side with the two hydrogen molecules is positive and the side with oxygen is negative. Water's polarity is what allows all its other properties to exist.

Cohesion:
Cohesion is a direct effect of polarity. Because one side of the molecule is positive and the other negative, water molecules attract. Molecules form hydrogen bonds and in this way are able to stay together. This is clearly shown in gif below where the water stays together in a blob. This property allows them to stick together and create something called surface tension.

Surface Tension:
Surface tension is created by cohesion. With the hydrogen bonds keeping the molecules together, a thin film is created on the surface. This is able to support some types of insects. Surface tension can be seen in the gif as the outer surface that wobbles with the water.

Adhesion:
Adhesion is another effect of water's polarity. It allows water molecules to stick to other polar molecules. Just like cohesion, the positive side of water attracts the negative side of another molecule and the negative side attracts the positive. In the gif below it can be seen that the water is attracted to the washcloth and the person's hand.

Capillary Action:
Capillary action occurs due to water's adhesion. Because water's adhesion attracts it to other materials, water tries to touch as much of it as possible. When water is placed in a thin tube made of another polar material, it will seemingly climb up the tube. Capillary action is what allows plants and trees to transport water from the ground into the highest point of the plant.

Universal Solvent:
Water is commonly referred to as the universal solvent. This is because it is able to dissolve more substances than any other liquid. Once again it is due to water's polarity. Because water is polar, it attracts many substances. Not only that, it's pull is so strong that it often ends up breaking the bonds between the other

Fresh, But Not Clean: Moon Craters in Mare Tranquillitatis | NASA
Similarly sized craters, one is fresh and the other is old.
LROC NAC image M131515002R showing two similarly sized craters, ~500 m in diameter, but one is littered with boulders and the other is not.  This boulder discrepancy is most likely due to age differences between the two craters. Image width is ~2 km, and North points up. Courtesy of NASA's Lunar Reconnaissance Orbiter (LRO).
 
There are several distinguishing properties of craters that help lunar scientists determine their ages. As craters get older their appearance changes through exposure to solar wind bombardment and other impacts (collectively called space weathering), and even gravity has an effect. Effects of the solar wind lower the reflectance of the surface; so regolith (soil) that was excavated by recent impacts has higher reflectance than the background surface, this is why small young craters have visible crater rays. New impacts pulverize rocks that were ejected during the formation of an older crater and disturb the shape by causing moonquakes. Also, gravity works to alter the shape of a crater by pulling material down its walls in a process called slumping, this causes craters to have a smoother appearance.

This image showcases two similarly sized adjacent craters (each ~500 m in diameter) located in Mare Tranquillitatis (see WAC context image below) with very different appearances. The area surrounding the top crater is littered with boulders in all directions. Wheras the more southerly crater has only a few rocks near its rim. Where did the boulders come from in the first place? And did the lower crater originally have boulders?

Since the mare basalt formed from layers of lava that hardened into solid rock, it is likely the boulders are coherent fragments of those thick layers (a few to tens of meters thick) that were broken up and ejected during the impact event. Since these two craters are so close and both formed in the mare it is very likely that the lower crater also had a large grouping of boulders in its ejecta field. The dissimilarity between these two craters is most likely due to age difference. Over time (perhaps a couple of billion years) the original boulders around the lower crater were slowly ground down by micro-meteorite bombardment - think of this process as cosmic sand-blasting! The boulders around the younger crater (top) have not had time to be pulverized by other impacts, but stick around for a billion years and you can watch these boulders slowly disappear!

Planetologists of the +Université de Liège (ULg)   observe a #transpolar #arc in #Saturn’s auroral footprints for the first time. A rare phenomenon, considering the planet’s characteristics, and one whose existence no-one had suspected. This research was made possible with the help of +Hubble Space Telescope  .

Tectonic Movement ~ Earth's Plates Change Over Time!

Earth's Plates Change Over Time

⇛ The GIF is showing frame by frame in 1 million year increment model of tectonic movement.

⇚ According to Sabin Zahirovic, a geodynamicist at the University of Sydney in Australia the tectonic plates can change their motion (speed and direction) over geologically short periods of time, about 1 million years.

⇎ Earth is in a constant state of change and it looks different than it was 250 million years ago when there was only one continent, called Pangaea, and one ocean, called Panthalassa.

⇕ At an average rate of 1.53 cm, land masses move apart and toward each other. The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other.
