Amateur Astronomer Spots Strange Cloud Formations On Mars

The linked article is fairly contradictory on several points. The glaring one is this:

" It was first seen on the evening of March 20th. Jaeschke alerted the international Mars observing community about the odd "extension" at 190.5? east, 43.7? south, just before the area that rotates into daylight. The odd feature was visible in all color-filtered exposures from near-infrared to blue light. Jaeschke produced the animation below.

The feature was also reportedly captured by other amateur astronomers over the past few nights. Some astronomers in Europe have seen it as far back as March 12th."

So, it was NOT first seen on the 20th, but rather on the 12th in Europe, and the guy in West Chester is not the discoverer of it.

UPDATE: Air Canada Ramp Workers Stage "Wildcat" Strike at Pearson







3/23/2012

Air Canada is scrambling after Pearson's ground crew staged a sudden "wildcat" strike, which lasted until late Friday morning. The strike caused a number of delays and cancellations - currently being dealt with.?

The workers were set to strike during march break but labour minister Lisa Raitt stepped in with back to work legislation.

?Air Canada confirmed that baggage handlers at Montreal's Trudeau had also walked off the job on a wildcat strike.

Autonomous University of Barcelona researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using superconductor and ferromagnetic materials available on the market. The invention is published this week in the journal Science.

The cylinder is built using high temperature superconductor material, easily refrigerated with liquid nitrogen and covered in a layer of iron, nickel and chrome. This simple and accessible formula has been used to create a true invisibility cloak.

The cylinder is invisible to magnetic fields and represents a step towards the invisibility of light - an electromagnetic wave. Never before had a device been created with such simplicity or exactness in theoretical calculations, or even with such important results in the laboratory.

Researchers at UAB, led by ?lvar S?nchez, lecturer of the Department of Physics, came up with the mathematical formula to design the device. Using an extraordinarily simple equation scientists described a cylinder which in theory is absolutely undetectable to magnetic
fields from the outside, and maintains everything in its interior completely isolated from these fields as well.

Equation in hand and with the aim of building the device, UAB researchers contacted the laboratory specialising in the precise measurement of magnetic fields at the Institute of Electrical Engineering of the Slovak Academy of Sciences in Bratislava. Only a few months later the experimental results were clear. The cylinder was completely invisible to magnetic fields, made invisible whatever content was found in its interior and fully isolated it from external fields.

The superconductor layer of the cylinder prevents the magnetic field from reaching the interior, but distorts the external field and thus makes it detectable. To avoid detection, the ferromagnetic outer layer made of iron, nickel and chrome, produce the opposite effect. It attracts the magnetic field lines and compensates the distortion created by the superconductor, but without allowing the field to reach the interior. The global effect is a completely non-existent magnetic field inside the cylinder and absolutely no distortions in the magnetic field outside.

Magnetic fields are fundamental for the production of electric energy - 99% of energy consumed is generated thanks to the magnetic camps within the turbines found in power stations - and for the design of engines for all types of mechanic devices, for new advances made in computer and mobile phone memory devices, etc. For this reason controlling this field represents an important achievement in technological development. Scientists are perfectly familiar with the process of creating magnetism. However, the process of cancelling at will is a scientific and technological challenge, and the device created by UAB scientists opens the way for this possibility.

The results of this research project also pave the way for possible medical applications. In the future, similar devices designed by UAB researchers could serve to block a pacemaker or a cochlear implant in a patient needing to undergo a magnetic resonance.

ABSTRACT
Invisibility to electromagnetic fields has become an exciting theoretical possibility. However, the experimental realization of electromagnetic cloaks has only been achieved starting from simplified approaches (for instance, based on ray approximation, canceling only some terms of the scattering fields, or hiding a bulge in a plane instead of an object in free space). Here, we demonstrate, directly from Maxwell equations, that a specially designed cylindrical superconductor-ferromagnetic bilayer can exactly cloak uniform static magnetic fields, and we experimentally confirmed this effect in an actual setup.

Within July This year an alternative version of the Xbox premiered updating that old Xbox models. We is going to be studying the variations between your various Xbox Arcade Games up to now.

Xbox 360 console Primary: Your Xbox 360 system Central was already released with the particular Xbox 360 Pro in The fall of August 2005. The particular system would have been a simple one missing a difficult travel that intended you?ll be able to not really retailer video games into it or use Xbox Stay. The gaming console have been not necessarily compatible with games through Microsoft?s very first games console. One of the many difficulty with this console has been the problem regarding overheating. This kind of style has been ceased and replaced together with the Xbox 360 system Game program.

Xbox live 20 GB Expert:Your 20GB Pro (also referred to as Xbox 360 system Premium) had been one of several gaming systems introduced inside June 2006. Your console was capable of playing a few of the games coming from your ex groundbreaking gaming system. Illustrates of the system add the power to play online games within High Definition, connect to various other players web enjoy game titles via Xbox live reside. In addition the particular gaming system has a High definition multimedia interface ouput which has a solution involving 1080p. Nonetheless this particular model has been ceased throughout August involving 2008 and also substituted for a new 60GB version from your package in the same value. Among the issues of this particular Xbox 360 system 20GB Expert has been the actual red ring of dying that manufactured the gaming system in order to lock up.

Xbox 360 Game: This method exchanged the Minecraft Texture Maps within October associated with ?07 and ended up being best pertaining to everyday avid gamers. Like the ?Core?, the device didn?t have a tough generate rather a 256MB associated with memory space ended up being supplied that was afterwards up-graded to 512MB. Players necessitating extra hard disk drive room may however purchase one more hard drive which could end up being fixed externally towards the system. Also included had been an invisible operator, HDMI-output assist and also 5 Xbox 360 Live Video games. Your Arcade system ended up being changed in July This year using the 4G Xbox 360 system Slim gaming console.

Xbox 360 system Top notch: This method was published in 04 ?07 and showcased any 120GB harddrive by using a dark flat finish. The Xbox 360 elite Top notch are also able to play many of the aged Xbox games as well as support for just about any cellular operator along with headset. In addition, it ended up being efficient at linking to be able to Xbox 360 Live the place that the game lover can down load game titles as well as embark on multi-online participate in. The equipment got concerns between that had been the high in volume Digital video disc drive along with air conditioning lover.The Xbox Top-notch gaming console afterwards swapped out the particular Xbox Top quality 60GB for a similar value and have become outdated with all the ease Xbox 360 slim variation.

Xbox 360 system Tremendous Top-notch: The gaming system very first made an appearance throughout 2009 coupled with a number of similarities towards the Xbox 360 system Professional nonetheless differed for the reason that that experienced a 250GB hard disk as well as has been packaged along with a pair of wifi control. Your Xbox 360 system Tremendous Professional may be distributed just like a pack while using subsequent video games: Call of Duty: Mw2, Forza Motosport Several, Halo Three or more, Phone 3: ODST and also Last Illusion XIII.

Xbox Lean: In 06 This year Microsof company launched the actual used golf balls and implemented the idea using the relieve the actual 4GB lean model in July of The year of 2010. Your lean units are generally alternatives for many old Xbox 360 system models. The particular slender versions were a marked development upon past gaming systems, correcting amongst others issues similar to loud supporter noises along with energy usage. Also the Xbox 360 system Trim patterns possess built-in Wireless and are also Microsoft kinect all set. In terms of design and style the actual 4GB carries a black matte complete, as the 250GB variation features a lustrous dark-colored end.

Establishment starts to coalesce behind Romney

(AP) ? The Republican establishment started to coalesce around Mitt Romney in earnest on Wednesday, with Jeb Bush and other leading Republicans pressuring Rick Santorum to leave the race after a thumping in the Illinois primary.

But, on what should have been a triumphant day, Romney also found himself having to defend his conservative credentials anew after one of his own top advisers quipped that the GOP front-runner's policy positions are "almost like an Etch A Sketch" in that they could be shaken away and redrawn.

"The issues I'm running on will be exactly the same," the former Massachusetts governor said in Arbutus, Md., as Republicans and Democrats alike mocked him. "I'm running as a conservative Republican. I was a conservative governor. I will be running as a conservative Republican nominee ? hopefully, nominee at that point. The policies and the positions are the same."

The remark earlier in the day by adviser Eric Fehrnstrom fueled criticism that Romney molds his principles to fit with political goals. Democrats pounced, and by day's end his GOP opponents were waving the draw, shake and erase toys at campaign events in Louisiana.

It all nearly overshadowed the endorsement from Bush, the son of one president and the brother of another. He had stayed out of the race for months, and some party elders publicly had urged him to become a candidate as Romney struggled to close the deal with the conservative base of the party.

Bush refused, and on Wednesday he made his preference in the race known after Romney's double-digit Illinois victory.

"Now is the time for Republicans to unite behind Gov. Romney and take our message of fiscal conservatism and job creation to all voters this fall," Bush said in a written statement. He congratulated the other Republican candidates "for a hard-fought, thoughtful debate and primary season."

His backing comes amid fresh signs that big GOP donors and other party figures will follow Bush's lead after sitting on the sidelines for much of the primary season. Romney is on pace to win the nomination in June. He has 563 delegates in the overall count maintained by The Associated Press, out of 1,144 needed to win the party nod. Santorum has 263 delegates, Newt Gingrich 135 and Ron Paul 50.

Hours after Bush weighed in, Bob Dole, the former Senate majority leader and a longtime Romney supporter, suggested that Santorum must decide soon whether to stay in or surrender his bid for the nomination.

"Rick, I think, he's got a real problem," Dole, who became the GOP nominee in 1996 on his third try, told The Associated Press in a telephone interview. "It's getting close to the point where he's got to take a hard look at it."

At the same time, campaign finance reports released Tuesday showed that big donors to a GOP political organization founded by political strategist Karl Rove have boosted their financial support for Romney in recent weeks.

Bush's support came as a surprise to the Romney campaign. The former Florida governor personally contacted Romney Wednesday morning to say he planned to make the endorsement.

Romney made one quick public appearance in Maryland on Wednesday ahead of the April 3 primary there. He planned to spend much of Thursday personally courting members of Congress and other officials in Washington.

But the Etch A Sketch remark threatened to dog him.

It happened early Wednesday on CNN when Fehrnstrom was asked if the extended primary fight "might force the governor to tack so far to the right it would hurt him with moderate voters in the general election."

Fehrnstrom responded: "I think you hit a reset button for the fall campaign. Everything changes. It's almost like an Etch A Sketch. You can kind of shake it up and restart all over again." The aide didn't back away from the comment when asked to clarify it. He said only that the general election is "a different race, with different candidates, and the main issue now becomes" exclusively President Barack Obama.

It didn't take long for the Democratic National Committee and Romney's Republican rivals to seize on the remark.

In Louisiana, Santorum brandished an Etch A Sketch and told voters he is a candidate who stands "firmly on the rocks of freedom, not on the sands of an Etch A Sketch toy."

Gingrich stood on stage elsewhere in the state and explained to his audience just what the toys were. "Gov. Romney's staff, they don't even have the decency to wait until they get the nomination to explain to us how they'll sell us out," he said. "I think having an Etch A Sketch as your campaign model raises every doubt about where we're going."

Louisiana holds its primary Saturday. Santorum is favored in the state, though Romney's allies are airing TV ads there even though the South has proven less hospitable to Romney.

Beyond Saturday, polls show Romney has the advantage heading toward Maryland's April 3 primary.

For his part, Obama on Wednesday headed to Nevada, New Mexico and Oklahoma on a trip aimed at answering critics of his energy policies, sure to be a key issue in the fall campaign. His first stop was a plant in Nevada that uses solar panels to power homes, part of an effort to highlight his programs to expand renewable energy sources.

The president's GOP critics poked back at Obama before Air Force One even took off.

Gingrich issued a statement saying Obama was answering a real-world problem with a "solution that is totally disconnected from the practical realities of the world and has little chance of success." Crossroads GPS, the nonprofit arm of a Republican super PAC, launched an ad on TV stations in the areas on Obama's itinerary and on national cable channels faulting the president for "bad energy policies" that are driving up gasoline prices.
