The snow on Mars fell from clouds around the planet's south pole during the Martian winter spanning 2006 and 2007, with scientists discovering it only after sifting through observations by NASA's Mars Reconnaissance Orbiter (MRO). The Martian south pole hosts a frozen carbon dioxide — or "dry ice" — cap year-round, and the new discovery may help explain how it formed and persists, researchers said.

Snow fall - at least on Earth - is not wierd at all. However, I'd caution against trying to make a snowball with dry ice. Remember those roses shattered in high school chemistry class? Yeah, it'd be kind of like that.

One such tantalising hint was discovered by the NASA Opportunity Rover, which found small spherical hematite balls, dubbed ‘blueberries,’ in the Martian soil.

These were originally thought to have provided the first evidence of liquid water on Mars, but their existence may hold an even more profound implication.

Now researchers from the University of Western Australia and University of Nebraska have found that such iron-oxide spheroids, when they appear on Earth, are formed by microbes.

The starry-skied planets are two so-called hot Jupiters, which are massive, gaseous orbs that are boiling hot because they orbit tightly around their parent stars. Each hot Jupiter circles a different sun-like star in the Beehive Cluster, also called the Praesepe, a collection of roughly 1,000 stars that appear to be swarming around a common center.

Poughkeepsie Journal: “Any way you dissect it, from a moral or religious standpoint, those protesters broke our commandments,” said Umar Ahmad, a longtime member of the Mid-Hudson Islamic Association located in the Town of Wappinger. “What happened in Libya is unforgivable.”

I am not a Muslim. I do have Muslim members of my family, as well as agnostic, Jehovah's Witness, nondenominational, etc. We respect one another. Proselytizing one another has never occurred in any conversations I've had with them. What counts most is the relationship; the familial bond.

I reject the notion any culture's sacred text - Buddhist, Christian, Hebrew, Hindu, Mormon, Muslim et al - is somehow in some bigoted comparison, worthy of desecration. I reject the notion of demonizing Agnostics or Atheists. I reject - as does the US Constitution - the idea of religious tests as a qualifier for elected office (though news pundits seem to count how many times the president uses the word "God" - and he does quite often - as if this is relevant). I reject the notion that an amateurish video of moribund, racist stereotypes falls under "free speech" and "our American values," unless those values now typify the classroom bully; the boot of empire stamped on the neck of the world. Freedom of speech does not give one the right to yell firein a building not ablaze!

I am as diminished by the loss of diplomats abroad as I am military service members deployed, as I am the senseless loss of life in inner cities across the United States.

Simple, elegant, sober, reflective and quite presidential.

It is in times of triumph and tragedy our leaders are called upon to quell our fears; raise our hopes. Personal vendettas and assaults are the mark of petty minds, I am particularly diminished by candidates that would take death so lightly as to score political points.

Isaiah 11:6 ends: ...and a little child shall lead them.I end with this photo from Facebook, the future meek that will "inherit the earth." I wish mom could see it. I think it would make her smile, and speaks more volumes than the cleverest self-serving sound bite:

Happy birthday, mom.

Mathematician Shinichi Mochizuki of Kyoto University in Japan has released a 500-page proof of the abc conjecture, which proposes a relationship between whole numbers — a 'Diophantine' problem.

The abc conjecture, proposed independently by David Masser and Joseph Oesterle in 1985, might not be as familiar to the wider world as Fermat’s Last Theorem, but in some ways it is more significant. “The abc conjecture, if proved true, at one stroke solves many famous Diophantine problems, including Fermat's Last Theorem,” says Dorian Goldfeld, a mathematician at Columbia University in New York. “If Mochizuki’s proof is correct, it will be one of the most astounding achievements of mathematics of the twenty-first century.”

Like Fermat’s theorem, the abc conjecture refers to equations of the form a+b=c. It involves the concept of a square-free number: one that cannot be divided by the square of any number. Fifteen and 17 are square free-numbers, but 16 and 18 — being divisible by 4² and 3², respectively — are not.

The Teleportation Physics Study was done by Eric Davis of Warp Drive Metrics. Its purpose -

"This study was tasked with the purpose of collecting information describing the teleportation of material objects, providing a description of teleportation as it occurs in physics, its theoretical and experimental status, and a projection of potential applications. The study also consisted of a search for teleportation phenomena occurring naturally or under laboratory conditions that can be assembled into a model describing the conditions required to accomplish the transfer of objects."

Judging from the LA Times, the reason for the tepid jobs numbers yesterday was because "OGs" are being called back to the work force, or not leaving it for younger workers, more apt to purchase stuff in our consumer-driven economy. So they stay home longer, having as much sex as before and procreating less (and those that do bring the bundle home), mooching off mom, dad cable TV and Internet access. So much for Carrousel. A simple math question: is 96,000 greater than zero? It's not ideal, but far better than where we've been.

I fear our ignorance, our worship of without-flaw market deities and hostility to reality will not lead to a blissful end.

This is a challenging time for the US and for US science. The economy, though it is beginning to show some positive signs, is still in bad shape. Extraordinary numbers of Americans are without jobs. The public holds a record-low opinion of government. The integrity of the scientific process is being questioned, and pressure to reduce federal spending is fierce.

The irony is that the demand for services provided by agencies such as the National Oceanic and Atmospheric Administration is at an all-time high and growing. Our ability to deliver those services depends in part on our scientific enterprise. One significant reason why demand for services is growing is the increased frequency and intensity of extreme weather events. Last year, new records were set in the US for tornadoes, drought, wind, floods, and wildfires. Heat records were set in every state. At one time last summer, nearly half of the country’s population was under a heat advisory or heat warning. In late November, hurricane-force winds hit parts of Wyoming, Utah, Nevada, Arizona, New Mexico, and California, with winds reaching 97 mph in Pasadena.

Another quote from Jefferson before I go:

The ENCODE project (Encyclopedia of DNA elements), which involved hundreds of researchers in dozens of labs, also produced what some scientists are saying is like Google Maps for the human genome.

"So the most amazing thing that we found was that we can ascribe some kind of biochemical activity to 80 percent of the genome. And this really kind of debunks the idea that there's a lot of junk DNA or really if there is any DNA that we would really call junk," NHGRI's Feingold said.

What has been called junk DNA is actually teeming with an intricate web of molecular switches that play crucial roles in regulating genes. The ENCODE project scientists found at least 4 million of these regulatory regions so far.

While working on her Ph.D. in theoretical nuclear physics at the University of Maryland at College Park, Dr. Aziza received a Mass Media Science & Engineering fellowship from the American Association for the Advancement of Science (AAAS) and was assigned to CNN’s science and technology unit in Atlanta Georgia. During her fellowship, she gained hands-on experience producing science news video segments which aired on CNN’s newscasts. This experience launched her career as a TV science producer and on-air correspondent.

An international team of scientists led by Thornton Glover of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) used the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory to mix a pulse of superbright x-rays with a pulse of lower frequency, “optical” light from an ordinary laser. By aiming the combined pulses at a diamond sample, the team was able to measure the optical manipulation of chemical bonds in the crystal directly, on the scale of individual atoms.

The researchers report their work in the August 30, 2012 issue of the journal Nature.

Geoengineering aims to mitigate man-made climate change by making large-scale modifications to the Earth's surface or atmosphere. One of the main proposals discussed by scientists is stratospheric albedo modification: changing the reflective power of the atmosphere 10–50 km above the Earth's surface so that more solar radiation is reflected back into space. Such a modification would be achieved by pumping tiny particles known as aerosols into the upper atmosphere.

Now Seth Caliga and pals at the University of Colorado and National Institute for Standards and Technology in Boulder have built a version of this kind of circuit that works with atoms rather than electrons.

Their atomtronic circuit generates an oscillating atom current that emits matter waves in which atoms carry energy through space.

The heart of their device is an atomtronic transistor--an optomagnetic trap with three compartments that can hold a Bose Einstein Condensate of rubidium atoms cooled almost to absolute zero.

In an analogy with electronic transistors, Caliga and co call these compartments the source, gate and drain (with the gate sandwiched between the source and drain). The optical barrier between the compartments prevents atoms from moving freely between them.
