Agriculture has one hell of a footprint, occupying 37.6 percent of earth’s land area, or about 0.7 hectares (1.7 acres) per person to feed our world's

Tonight due to powerful X-class solar flares earlier this week we may get to see the Aurora Borealis at latitudes where it usually is not visible.    The Northern Lights are the result of charged particles from the Sun interacting with Earth's magnetic field.  They ride the lines of magnetic force towards the north and south pole and release light as their acceleration changes.   



This is one of the most beautiful sights in nature. A view of the Aurora Australis from the international space station.

The object actually appears as it is pictured. It is not an optical illusion. The image was not created using an “in camera” special effect (no special lighting, no filters other than the built-in infrared filter, no mirrors, or any other “in camera” special effect technique). The image has not been modified with digital photography editing software. The object was not taped, or glued, or otherwise fastened together. The object was created using a single piece of ordinary twenty pound bond computer printer paper and a pair of scissors. Are you able to solve the puzzle of how it was made?

ESA Satellites are showing clouds of sulfur dioxide exiting from Iceland’s Bardarbunga volcano.

It may be mostly hidden underneath the Vatnajokull glacier in the center of the country but Bardarbunga isn't shy about saying hello, it has had up to 400 eruptions in the last 10,000 years, one of which produced more lava than any other volcano on Earth during that time.

23 of those were geologically recent.

Bardarbunga eruptions seem to happen even more often than colony collapse disorders in bees, so Iceland knows it's best not to get too complacent when something sitting on two volcanic rift zones starts to put on a show:  It seems to erupt twice per century on average and the last one was in...1910.

Tick tock, tick tock...

The minor controversy over whether the 38 foot wide gouge near Managua Nicaragua is a impact crater leads me to the question, how easy is it to tell by sight alone if something is an impact crater or not?  So let's play crater or not crater. 

To find the answer click the pictures and there will be a link to a source which shows that one image is a impact crater or not impact crater.  That is in cases where it's uncontroversially clear. 

The first candidate.

If you want the best education and you are rich or are a non-Asian minority born with your heart outside of your body, go to Princeton. If you are Asian and rich, go to Caltech.

If you are none of the above, but still smart enough to get into a top school, U.C. Berkeley is the best place to be for the 17th straight year, according to US News  &  World Report rankings, which mean quite a lot to schools in the top 20 and little to anyone else. Berkeley again placed 20th overall and, since it is a public university, its tuition and fees are low compared to Caltech and Stanford, at least if you live in the state.
The field of physics attracts crackpots. It is impossible to completely avoid them, and after a nasty incident in 1952 with an actually mentally ill individual who was upset no one would listen to his theories concluding electrons don't exist, the American Physical Society decided to give up trying to avoid them. A membership and willingness to pay a fee will guarantee you the opportunity to share your ideas at major APS meetings.

Despite challenges, prescription drug monitoringprograms are essential tools in ensuring opioids and other addictive medicinesare prescribed and used appropriately.

The purpose of this article is to present a framework and a method for cyber-target categorization. The framework contains factors, which influence on cyber targeting process and the presented categorization method provides an example, how cyber-targets could be categorized to support targeting decision making.

The article is based on literature study. Research method was to build an analogy between conventional and cyber targeting.

Cyber targeting does not seem to be studied widely, but the common approach to cyber security seems to be “threat-based”. This article presents a new categorization criteria and method for cyber-target analyze, with a target-based approach.

"If you have seen the movie Particle Fever about the discovery of the Higgs boson, you have heard the theorists saying that the only choices today are between Super-symmetry and the Landscape. Don’t believe them. Super-symmetry says that every fermion has a boson partner and vice versa. That potentially introduces a huge number of new arbitrary constants which does not seem like much progress to me. However, in its simpler variants the number of new constants is small and a problem at high energy is solved. But, experiments at the LHC already seem to have ruled out the simplest variants.
