Added Yin What's really exciting is that this electron polarization exhibits strong coupling. The quadrupole polarization of the iron which indicates the orbital fluctuation couples intimately with the arsenic dipole polarization--this mechanism may be key to the emergence of high-temperature superconductivity in these iron-based compounds.
And our results may guide the design of new materials. This study explored the orbital fluctuations at room temperature under static conditions

#Cosmic roadmap to galactic magnetic field revealedscientists on NASA's Interstellar Boundary Explorer (IBEX) mission including a team leader from the University of New hampshire report that recent independent measurements have validated one of the mission
and particles at the edge of our solar system that appears to be a directional roadmap in the sky of the local interstellar magnetic field.
Unknown until now the direction of the galactic magnetic field may be a missing key to understanding how the heliosphere--the gigantic bubble that surrounds our solar system--is shaped by the interstellar magnetic field
Establishing a consistent local interstellar magnetic field direction using IBEX low-energy neutral atoms and galactic cosmic rays at ten orders of magnitude higher energy levels has wide-ranging implications for the structure of our heliosphere
The cosmic ray data we used represent some of the highest energy radiation we can observe
How magnetic fields of galaxies order and direct galactic cosmic rays is a crucial component to understanding the environment of our galaxy which in turn influences the environment of our entire solar system
and our own environment here On earth including how that played into the evolution of life on our planet.
Notes David Mccomas principal investigator of the IBEX mission at Southwest Research Institute and coauthor on the Science Express paper We are discovering how the interstellar magnetic field shapes deforms
and cosmic ray data with Voyager 1's measurements the Voyager 1 data provide a different direction for the magnetic fields just outside our heliosphere.
Now a whole new realm of science is opening up as we try to understand the physics all the way outside the heliosphere.

NASA study points to infrared-herring in apparent Amazon green-upfor the past eight years scientists have been working to make sense of why some satellite data seemed to show the Amazon rain forest greening-up during the region's dry season each year from June to October.
--but see a large amount of near-infrared light which plants primarily reflect. Scientists use the ratio of red and near-infrared light as a measure of vegetation greenness.
Numerous hypotheses have been put forward to explain why Amazon forests appear greener in MODIS data as the dry season progresses.
Perhaps young leaves known to reflect more near-infrared light replace old leaves? Or possibly trees add more leaves to capture sunlight in the dry season
or reflectance properties have distinct fingerprints in MODIS and GLAS data. Only one of the hypothesized mechanisms for the green-up changes in sun-sensor geometry was consistent with the satellite observations.
We think we have uncovered the mechanism for the appearance of seasonal greening of Amazon forests--shadowing within the canopy that changes the amount of near-infrared light observed by MODIS Morton said.
At this point the forest canopy is shadow-free highly reflective in the infrared and therefore very green according to some satellite vegetation indices.
Those reactive compounds altered Earth's radiation balance contributing a net global warming as much as two to three times greater than the effect of carbon dioxide according to the study published in the journal Geophysical Research Letters.

radiation which transfers thermal energy through electromagnetic waves and conduction which transfers thermal energy through the vibrations of neighboring atoms and molecules.
But she and her colleagues suspected that radiation might play a bigger role. The scientists performed some initial calculations that showed heat loss between two bodies separated by air would be dominated by radiation not conduction.
To further explore the radiative heat loss the team created a simple computer model consisting of a hot and a cold thermostat that roughly simulated an animal's warm body and the outside colder environment.
which absorb all of the radiation that strikes them. In a second version opaque grey-body shields were used.
All together the model suggests that the repeated backscattering of infrared light between radiative shields like individual hairs
With the right structure fur and feathers can generate efficient thermal insulation in the far infrared range
The idea is to multiply the interaction of electromagnetic waves with grey bodies--reflecting bodies like metals with very low emissivity
The QCL emits light from the mid-to far-infrared portion of the spectrum. That allows for far better detection of gases than more common lasers that operate in the near-infrared.
The technique called quartz-enhanced photoacoustic absorption spectroscopy (QEPAS) invented at Rice by Tittel Professor Robert Curl
The laser beam is focused between the two prongs of the quartz tuning fork. When light at a specific wavelength is absorbed by the gas of interest localized heating of the molecules leads to a temperature
With the help of real-time X-ray diffraction at the EDDI beamline of BESSY II HZB physicists around Roland Mainz and Thomas Unold could now observe how a phase transition from the metastable wurtzite phase to the stable kesterite phase leads

The Battle took place in 217 B c. between Ptolemy IV the King of Egypt and Antiochus III the Great the King of the Seleucid kingdom that reached from modern-day Turkey to Pakistan.
According to historical records Antiochus's ancestor traded vast areas of land for 500 Asian elephants whereas Ptolemy established trading posts for war elephants in what is now Eritrea a country with the northernmost population of elephants
In the Battle of Raphia Ptolemy had 73 African war elephants and Antiochus had 102 Asian war elephants according to Polybius a Greek historian who described the battle at least 70 years later.
A few of Ptolemy's elephants ventured too close with those of the enemy and now the men in the towers on the back of these beasts made a gallant fight of it striking with their pikes at close quarters
Ptolemy's elephants however declined the combat as is the habit of African elephants; for unable to stand the smell
In 1948 Sir William Gowers reasoned that Ptolemy must have fought with forest elephants that fled from larger Asian elephants as Polybius described.
Did Ptolemy employ African savanna elephants (Loxodonta africana) or African forest elephants (Loxodonta cyclotis) in the Battle or Raphia?

Reversing radiation's bad PRWOULD you eat a banana? Would you install a smoke detector in your home?

You'll get far more radiation from your bananas, smoke detectors and trips to Yosemite than you ever ever will from a nuclear power plant.
That's how I interpret a concise, handy new guide called Radiation: The Facts  by former Dartmouth professor Robert Hargraves.
Radiation is safe within limits, Hargraves reminds us throughout the easy-to-read 6-page brochure.
His point: The public is misinformed so about radiation that it is missing a golden opportunity to move the world onto a low-CO2 diet by shifting to nuclear power.
In his words: Â Nuclear power is a green environmental solution. It generates no CO2. The fuel is cheap and inexhaustible.
Green nuclear power can solve the global crises of air pollution deaths and climate change. Cheap energy can help developing nations escape poverty
and let industrialized nations improve economic growth. Is it safe? The primary obstacle to nuclear power is misunderstanding of radiation safety.
Hargraves doesn't actually state that bananas and smoke detectors give us more radiation than nuclear plants do,
but that's the message between the lines. He does indeed point out that bananas and smoke detectors emit.
and Chernobyl for instance-they do not emit radiation to the general public. It's all contained.
The average coal plant has spewed far more radiation over the years than has nuclear. Coal operators are allowed to do this under naturally occurring radioactive materials (NORM) exemptions.
But back to the brochure. Hargraves reminds us that in our daily lives we encounter constant natural background radiation from sources like cosmic rays, breathing radon, ingestion of food and water,
and proximity to rocks such as granite (There's your Yosemite. I love its granite cliffs and domes.
I'll blow a kiss to their radiation). He points out that people living in places like Denver
and Finland incur higher natural background radiation-presumably because they are closer to the sun. Yet are they aglow?
Hargraves debunks an old guideline called Linear No Threshold (LNT) that states that the cumulative effect of repeated exposure to radiation can be devastating.
pointing out that the human body has natural healing powers that overcome any damage from small doses of radiation.
Yes, radiation can kill. Be careful with the stuff. But that's not a reason to oppose nuclear power.
 Especially alternative forms of nuclear reactors under development in some countries, which improve nuclear's safety performance to an even higher level,
Yes, it's time for more nuclear power. Â And for that to happen, it's time for the public to take a more measured view of radiation.
Not only is radiation all around us, it sustains us in many ways. The radioactive decay of Earth's core provides much of the heat that keeps us alive on the planet.
Radiation sterilizes food. Radiation serves us broadly in the medical field, both as a diagnostic and therapeutic tool.
In fact we are currently enduring a shortage of medical isotopes, which we could rectify if we had more nuclear reactors from
which to pull them. Radiation reminds me of the albatross: It performs wondrous things and it generally doesn't harm you,
yet it has a villainous reputation. The bird made famous in The Rime of the Ancient Mariner can fly incredible distances with a single flap of the wings.
The feathery creature used to be a good omen, until Samuel Taylor Coleridge's seafarer got hold of one and turned it into an impediment around  your neck.
Likewise, radiation can do so much good for mankind. It can provide clean power and medical miracles.
