Deep beneath Antarctica's ice, signs of bizarre cosmic particles

An observatory on the southern continent has detected high-energy neutrinos, some of which come from beyond our galaxy.

By Jesse Emspak, LiveScience August 23, 2015   

Buried deep in the Antarctic ice, an observatory has spotted ghostly, nearly massless particles coming from inside our galaxy and points beyond the Milky Way.

Finding these cosmic neutrinos not only confirms their existence but also sheds light on the origins of cosmic rays, the researchers said.

The IceCube Neutrino Observatory is made up of 86 shafts dug 8,000 feet into the ice near the South Pole. The shafts are equipped with detectors that look for the telltale light from high-energy particles plowing through the surrounding ice. [See Photos of the IceCube Observatory Buried in Ice]

Neutrinos have little mass, and zip through matter so easily that a block of lead a light-year across wouldn't stop them. These elusive particles come from high-energy sources: exploding stars, black holes and galactic cores among them.

Though they don't interact much with matter, occasionally one will hit an atomic nucleus on Earth. When that happens the neutrino generates a particle called a muon. That's what scientists look for when seeking neutrinos — the muons move faster than the speed of light in a solid (ice in this case) and generate light waves, like the wake of a boat in water, called Cherenkov radiation. They also show the paths of the neutrinos. (The speed of light is constant in a vacuum, but it is slower in a medium like ice or glass — this is what causes refraction. So the muons aren't actually breaking the speed of light limit). 

The IceCube project found neutrinos from outside our galaxy in 2013, but to confirm that detection the researchers, led by a team at the University of Wisconsin-Madison, had to make sure these neutrinos weren't coming from sources within our own galaxy (such as from the sun). To do so, they looked for neutrinos with similar energies that were coming from all directions at the same rate, meaning they are independent of the Earth's rotation and orbit around the sun — the only way that can happen is if the source is outside the galaxy.

The scientists also had to filter out muons created when cosmic rays crash into the planet's atmosphere. They used the Earth itself to weed out most of these muons, pointing the observatory through the Earth and toward the sky in the Northern Hemisphere (which is "down" with respect to Antarctica).

Over two years, between May 2010 and May 2012, the observatory logged more than 35,000 neutrinos, with 20 of those showing high enough energies to suggest they came from cosmic sources.

Those 20 neutrinos, called muon neutrinos, came from the opposite direction, but at approximately the same rate, as similar neutrinos observed in earlier runs. Since the rate at which they showed up was about the same throughout the observation, it means it didn't matter where the observatory was pointed as a result of the daily rotation and yearly orbit of the Earth — the result predicted for extragalactic neutrinos. [Wacky Physics: The Coolest Little Particles in Nature]

"At least a fraction of that flux is extragalactic origin," Albrecht Karle, a UW-Madison professor of physics and one of the senior authors of the new study, told Live Science. "This was a new discovery."

Those observations also told them something else: The energies of the muon neutrinos, and their numbers, didn't fit well with several models of their origins. The scientists don't address it deeply in their study ("We leave that to theorists," Karle said), but the data appear to show these muon neutrinos are probably not coming from gamma-ray bursts (GRBs), which are highly energetic events in space.

"There are some stringent upper limits of neutrinos from GRBs — we know they don't produce that many," he said.

Similarly, active galactic nuclei don't seem to be the culprit, either, though Karle said it's too soon to say for sure.

Other possibilities are galaxies going through bouts of rapid star formation, or masses of gas and dust that surround black holes at the galactic centers. As atoms get pulled into the maw of a black hole, they slam into each other more often at higher energies. Eventually some produce pions, neutrinos and photons. If that were the case, Karle said, then one would expect a nearly one-to-one ratio of high-energy neutrinos to accompanying photons. But that hasn't been confirmed or refuted yet.

A Few Good Women

Two US soldiers become symbols of new generation of female fighters

August 20, 2015 10:49 AM

Washington (AFP) - When two young women graduate from the US Army's prestigious Ranger School on Friday, they will cement their places at the forefront of a new generation of females in combat roles.

Local media have identified the two as Captain Kristen Griest, a military police officer from Connecticut, and 1st Lieutenant Shaye Haver of Texas, an Apache attack helicopter pilot.
They became the first women to complete the Ranger School combat leadership course that constitutes one of the most physically and mentally challenging military training programs.
Over a period lasting at least 61 days, participants endure patrol and combat simulations in the toughest of environments while often deprived of food and sleep.

Despite having made it this far, however, the two women will still not be allowed to serve with the elite 75th Ranger Regiment, which has yet to lift its ban on female soldiers.
But the Pentagon is putting finishing touches on a plan that would allow women access to all military posts, with a few exceptions which the Secretary of Defense will rule on in January 2016.

 

In this US Army photo, first Lt. Shaye Haver is shown here in Ranger School training during the Moun …

The success of Griest and Haver provides a welcome boost for backers of full gender equality in the military. The notoriously challenging Ranger School welcomed women for the first time this year, following President Barack Obama's 2013 request that the Pentagon order all branches of the armed forces to open up ground combat roles to women by 2016.

In an effort to show that the female participants in the program were treated the same as their male counterparts, the Army took special care to invite some reporters to see for themselves this summer.
The military's top brass seems keen to lift all restrictions on women -- provided they meet the criteria for specific positions.

 

In this US Army photo, Army Capt. Kristen Griest (L) participates in training during the Ranger Cour …

"If they can meet the standard, they should be able to go, and they should be able to earn their Ranger tab. And I think that's how we want to operate as we move forward," the now retired army chief of staff, General Ray Odierno, said earlier this month. Admiral Jonathan Greenert, outgoing chief of naval operations, seemed to echo that sentiment, telling Defense News that the US Navy plans to open its famed SEAL fighting units to women, provided they can pass the notoriously difficult training course.

"Why shouldn't anybody who can meet these (standards) be accepted? And the answer is, there is no reason," he was quoted as saying. The Navy SEALs have carried out some of America's most dangerous and storied raids, including the May 2011 killing of Osama bin Laden, the late Al-Qaeda leader, in Pakistan. Some experts argue that in actual fact women are already in the line of fire, especially in wars without any clearly defined frontlines such as those the United States fought in Iraq and Afghanistan.

For example, women found themselves at the sides of special US forces during night raids in Afghanistan, and were tasked with establishing contact with Afghan women who would never have spoken to men.

- Debate not over -
The debate is not over. The military's services are putting final touches on their recommendations and are due to submit their requests for exceptions to opening up posts to women by the end of September.

But the Center for Military Readiness, for one, said on its website it "takes issue with Obama Defense Department leaders and 'politicians in uniform'" who "are putting gender politics above national security and the best interests of both women and men in the military."

"All of them are disregarding previously undisclosed military combat experiments, which show injury rates among women twice as high as men's," it said. For now, about 220,000 positions -- or roughly 10 percent -- remain closed to women.

Giant asteroid Heading Toward Earth?

Viral false asteroid report leads to NASA denial

 

False reports are swirling the Internet that a major asteroid is taking aim at Earth and could hit and cause massive destruction next month. The reports are so viral that NASA is responding, trying to flush that rumor.

"There is no asteroid threatening Earth," NASA declared in a press release issued Tuesday afternoon.
The NASA release goes on to say that "numerous recent blogs and web postings are erroneously claiming that an asteroid will impact Earth, sometime between Sept. 15 and 28, 2015."

Those reports apparently are far more specific about the location of the impact than they are about the date it might occur, even though a difference of an hour or two of Earth spinning would mean the difference of thousands of miles on an impact location. And the difference of 14 days would mean, well, who knows where it might hit? Whatever date it was supposed to hit, it would hit near Puerto Rico, NASA says the false reports typically state.

"There is no scientific basis -- not one shred of evidence -- that an asteroid or any other celestial object will impact Earth on those dates," Paul Chodas, manager of NASA's Near-Earth Object office at the Jet Propulsion Laboratory in Pasadena, California, states in the release.

"If there were any object large enough to do that type of destruction in September, we would have seen something of it by now," he states.

Another thing Chodas and his team do know -- this isn't the first time a wild, unsubstantiated claim of a celestial object about to impact Earth has been made, and unfortunately, it probably won’t be the last, NASA reported.  It seems to be a perennial favorite of the World Wide Web, NASA's release notes.

Here's a link to the full NASA release. And here's a link to NASA's asteroid-watch project's webpage.

This new nuclear-armed US bomb may be the most dangerous weapon in America's arsenal

By Jeremy Bender July 28, 2015 2:07 PM

.

(Michael Jackson/US Navy) The B61-12 bomb will be integrated with the F-35. The US just introduced a new type of bomb into its already extensive arsenal, and it may just be the most alarming US weapon yet, Zachary Keck writes for The National Interest. The new bomb is the B61-12. On its surface, the bomb does not appear to be as dangerous as other weapons in the US arsenal. Although the B61-12 is nuclear-armed, it has a yield of 50 kilotons — tiny compared to the largest nuclear bomb that the US possesses, which has a yield of 1,200 kilotons. 

But as Keck notes, that difference in explosive power doesn't tell the entire story. "What makes the B61-12 bomb the most dangerous nuclear weapon in America’s arsenal is its usability," Keck writes. "This usability derives from a combination of its accuracy and low-yield." According to the Federation of American Scientists, the B61-12 will be able to strike within 30 meters of its target. This accuracy allows the bomb to destroy targets that would have previously necessitated the use of a larger but more indiscriminate weapon.

As a result of the bomb's relatively low yield, the weapon would produce less nuclear fallout than earlier nuclear weapons, something which would limit unintended casualties from a nuclear attack. But this lower fallout also lowers the cost and scope of a nuclear strike — which could in turn increase the possibility that the bomb would actually be used in a military engagement. 

As it is, the B61-12 may actually expand the range of possible US nuclear targets. In a 2014 conference organized by the Stimson Center, retired US Air Force General Norton Schwartz said that the B61-12's target set goes beyond that of previous gravity-guided nuclear bombs in the US military. This effectively means that the US could now consider the use of aircraft-delivered lower-yield nuclear weapons in a wider range of scenarios.

The concern over the B61-12 — and the thing that could make it is the most dangerous bomb in the US arsenal — is that such an accurate and usable nuclear weapon could encourage military thinkers to start imagining a wider variety of situations in which the use of nuclear weapons would be acceptable.
Once the B61-12 is fully tested and deployed, it will be integrated into existing NATO forces and the F-35 in order to enhance the alliance's nuclear posture in Europe.

Scientists discovered the last lake on Mars, which might be preserving ancient life

By Jessica Orwig August 11, 2015 5:51 PM

.

(ESO/M. Kornmesser) Illustration of what Mars would look like with water.

A trio of scientists says they've identified the best place to look for evidence of ancient life on Mars — one of the youngest lake-bearing basins ever discovered. 

Though Mars has no liquid water today, the Red Planet was submerged under vast oceans billions of years ago. And where there's water, there's the potential for life. Scientists suspected that after the oceans evaporated, that was it for water — and life — on Mars. But a recent paper published in the journal Geology says that's not the case. Mars had a second wave of surface water about 3.6 billion years ago — 200 million years after scientists thought Mars had seen the last of its liquid water. This water, the researchers report, was located in a lake inside a basin near the Martian equator, about 100 miles from where NASA's Opportunity rover rests today.

It is one of the youngest lakes and therefore possibly one of the last liquid water sources to ever exist on Mars, the researchers report.

The discovery is exciting for the prospect of ancient Martian life, explains lead author Brian Hynek who is a research associate at the Laboratory for Atmospheric and Space Physics at Colorado University-Boulder:
"Having a later stage of water on Mars is probably a good thing for the potential for life on that planet because it gave life more time to be conceived," Hynek told Business Insider. "There was life on Earth when this lake was active so by that analogy, we can say there's potential that Mars had microbial life and this was a great place where it could have resided."

Getting around a tricky problem

.

(NASA/JPL-caltech/University of Arizona) Crater in Meridiani Planum, where the researchers found evidence for one of the youngest lakes ever discovered.
The researchers are investigating the age and origin of hundreds of salt deposits across Mars to map how much water existed on the surface.  

"Just like on Earth, when salts are left somewhere, that probably means that water was there," Hynek said. "So, these are indicators that water was there in some form." Estimating the age of these salt deposits is tricky. The way scientists determine the age of anything on Mars is by counting the number and measuring the size of impact craters in that region. Then they compare this information to similar regions on the Moon, whose age we have a better handle on.

But wind has eroded the regions where these salt deposits are located, which makes it hard to estimate their age. This latest paper is the first time anyone has ever calculated with any confidence the age of one of these salt deposits, Hynek said.

Using images taken by NASA's Mars Reconnaissance Orbiter, which has been orbiting Mars since 2006, the team studied the terrain and geography around the basin. They found evidence to suggest that at one point, the lake grew large enough to spill over the rim of the basin, carving channels in its wake. 
The researchers traced these channels to neighboring volcanic plains hundreds of miles away that are about 3.6 billion years old. Because the water channels over-cut the volcanic plains, they must be younger. That means the lake must also be younger than 3.6 billion years.

Life locked in salt

.

(Promking at en.wikipedia) Bonneville Salt Flats in Utah are similar to the salt deposits on Mars.
Right now, there are no plans to visit this basin in search for the potential for life. But Hynek hopes that this latest paper will make the basin a more popular touch down point for the NASA Mars rover scheduled to launch in 2020. Hynek has a pretty good idea of where he'd look first. "I think you'd want to target the salt deposits," he told Business Insider. "As the water evaporates away a lot of organic matter and a lot of microbial evidence gets encased in salts and is preserved for long time periods."

Though there was liquid water in the basin, there are still other factors that would ultimately determine whether life could have existed there, Hynek cautions. The lake's salinity, acidity, oxygen levels, and available nutrients for food are all important.

The lake had a relatively low salt content, which would have made it ideal for life, Hynek said. However, the other three factors are hard to measure without sending a rover there to scoop up the soil and analyze what's in it. So far, this single lake is the only evidence for water on Mars around 3.6 billion years ago. Hynek plans to continue studying these salt deposits to see if there's more evidence of water on a younger Mars.

One of the F-35's most expensive features was made possible by flying saucers

By Jeremy Bender August 11, 2015 11:27 AM

.

(Lockheed Martin) An F-35B using its central lifting fan.
The US Air Force's push to develop operational flying saucers 60 years ago laid the conceptual groundwork for one of the variants of Lockheed Martin's F-35, MIT Technology Review reports. 
The F-35 comes in three variants, with key mechanical differences for the Air Force, Marines, and Navy - the F-35A, F-35B, and F-35C respectively. Of the three models, the F-35B is the most technologically different. Unlike the F-35A and F-35C, the Marines needed their variant to be capable of conducting short take-off and vertical landing (STOVL) operations.

This request necessitated that the F-35B be given a lifting fan. And, as Desire Francine G. Fedrigo, Ricardo Gobato, Alekssander Gobato note in a paper at the Cornell University Library, the F-35B's lifting fan has its conceptual roots in flying saucers.

Between 1954 and 1961, the US Air Force spent $10 million attempting to develop a flying saucer that became known as an Avrocar. The Avrocar was a vertical and/or short take-off and landing (V/STOL) saucer that was powered by one giant central fan.

.

Despite its seven years of development, the Air Force failed to make the Avrocar into a mission capable vehicle that could potentially replace helicopters. 

MIT Technology Review notes that the aircraft was "hot and almost unbearably uncomfortable for the pilot. And it demonstrated various idiosyncrasies such as taking five seconds to turn 90 degrees to the left but 11 seconds to turn the same amount to the right, presumably because of its central rotating fan." However, despite the Avrocars' failings, the technology did point researchers towards the feasibility of developing and embedding a central lift fan turbine within an aircraft for variations of vertical take-off and landing (VTOL) technology.  

.

(US Air Force)
"The concept of a lift fan, driven by a turbojet engine is not dead, and lives today as a key component of Lockheed X-35 Joint Strike Fighter contender," Fedrigo notes, adding that the conceptual framework of the Avrocar helped General Electric's own development of a booster fan propulsion system. 

Whereas the Avrocar's development ultimately failed, though, GE's "Vertifan" went on to prove the concept of successful lifting fan technology. This in turn lead to a DARPA sponsored development challenge that gave birth to lifting fans being used in the F-35B. The F-35B was declared ready for combat by the Marine Corps on July 31.

Archaeologists discover giant prehistoric monolith at the bottom of the Mediterranean Sea

August 4, 2015

 

At the bottom of the Mediterranean Sea, archaeologists uncovered a 10,000-year-old man-made monolith that they believe is evidence of a prehistoric civilization. The rock monument's colossal size (12 meters, or about 39 feet in height) suggests that quite a few people would have been needed to move it — something that would have been difficult if, as previously suspected, the inhabitants had been hunter-gatherers living relatively solitary lifestyles.

The find, which is actually the second of its type, has led archaeologists to suspect that civilization may have "already been shifting towards our modern way of life" earlier than previously thought, according to Evoanth. Together, the two monoliths (the other one was found in the Middle East) suggest that different groups in different parts of the world were beginning to develop a modern way of life simultaneously.
"What was it that was driving so many people, so far apart in the same direction?" asks Evoanth. We can't be sure, but it seems the scientists are one step closer to finding out. Becca Stanek

How federal agents foiled a murderous Jade Helm 15 retaliation plot

The Washington Post

Abby Phillip 8/5/2015

© Jay Janner/Austin American-Statesman via AP A convoy of National Guard troops moves on Camp Swift, which is also hosting the Operation Jade Helm 15 military exercise, in Bastrop,

Texas, on July 15. The men had a deadly plot to lure government forces into a trap, federal officials say, and were amassing a stockpile fit for war. There were Kevlar helmets and body armor, pipe bombs and handmade grenades, large amounts of gunpowder and dozens of rounds of ammunition for a military-grade sniper rifle.

Federal officials say three North Carolina men — Walter Eugene Litteral, 50; Christopher James Barker, 41; and Christopher Todd Campbell, 30 — spent months compiling their cache, much of it purchased through a military surplus store owner who became so concerned about the plot that the person became the FBI’s informant. The men were arrested Saturday and charged with conspiracy and amassing weaponry allegedly to combat what they believe is the government’s plan to impose martial law through (among other things) the controversial multi-state military exercise known as Jade Helm.

In January, the informant relocated the military surplus store to Gaston County, N.C. — a location that was just a few doors down from where Campbell operated a tattoo parlor. Almost immediately, Campbell told the informant of his “anti-government” views, according to federal court documents.

A month later, Campbell introduced the informant to Litteral. The two men told the informant that they believed “that the federal government intended to use the armed forces to impose martial law in the United States, which they and others would resist with violent force,” the court documents said. Specifically, they told the informant that the Jade Helm exercises planned in five states were a cover for the government’s plot to impose martial law. The exercises were scheduled to be conducted from July 15 to Sept. 15, and Litteral made it clear that he needed the military-grade items no later than the 15th of July.

Operation Jade Helm 15, a training exercise for Army Special Operations Forces, has spawned consternation and anti-government conspiracy theories. The exercises are taking place in Texas, along with Arizona, New Mexico, Utah and Colorado, according to the Army. By April, months before the training operation was scheduled, the purchases from the military surplus store began — all of them paid for in cash, according to court documents. There were plans, the documents allege, to make pipe bombs, explosive tennis balls covered in nails and coffee cans filled with ball bearings that would be detonated with a shot from a sniper rifle.

And by mid-June, those plans were beginning to crystallize.

According to the documents, Litteral was heavily armed with both legally and illegally obtained weapons. If government agents came looking for him at his home, Litteral allegedly told the informant in a phone conversation, he would be ready. “Lemme tell you something, I gonna have my f——- house rigged up; these motherf—— come try to come in my house, it’s gonna go off,” he said, according to the documents.

The documents indicated that Litteral told another person in a phone conversation: “I got a f—— .45 beside my bed. I got a .45 and a 9-mil in my truck. I’ve got a 9-mil and a .380, or a .380 in her car. Safe full of weapons. You know what? Every time I open up this damn safe, I mean I’ve got, I’ve got at least 30 weapons that I can see and some tucked all the way in the back back.”

The plan involved testing the explosives on land in Shelby, N.C. But the ambush against U.S. forces would take place on Litteral and Campbell’s a 99-acre camp in Clover, S.C. “According to [Campbell], he and Litteral intend to booby-trap the camp and draw government’s forces into the camp and kill them,” the warrant states. On June 30, according to documents, Campbell told the informant that he feared that the government would soon declare martial law, saying: “S— is gonna go down soon.”

In mid-July, Litteral attempted to buy a rifle for Barker, the third arrestee named in the conspiracy. Barker had been convicted of a felony and would not have been permitted to purchase a weapon.

But the purchase at the gun store was held up, first by a required three-day background check. Unbeknownst to Litteral, it was then held up even longer at the FBI’s request.

In a conversation on July 29, according to the documents, Litteral told Campbell that the delay infuriated him:

LITTERAL: “it would be good for trip but like I was telling him with the pipe bombs I’m making we need a fuse we need a fuse because these things if we put one here we’re gone.” Three days later, federal agents made a move, raiding two homes along with Campbell’s tattoo parlor and ultimately arresting all three of the men.

The men now face charges of conspiracy to violate laws governing firearms and explosive devices, which carry a prison sentence of up to five years and a $250,000 fine. Campbell separately faces an additional charge of receiving, possessing or making a firearm —which by definition includes a destructive device — which carries a maximum penalty of up to 10 years and a $10,000 fine, according to the FBI.
