This Video Montage of Saturn s Rings and Moons Is Simply Gorgeous

For more than nine years, NASA?s Cassini probe has orbited Saturn, examining its rings and moons in unprecedented detail and sending back images of things and places humans had never seen. Filmmaker Fabio di Donato has managed to collapse that discovery and wonder into four minutes. In a new film posted on Vimeo, di Donato cobbled together countless still images of the Saturnian system to compose a beautiful, literally otherworldly montage.

Among the stars of the film: Saturn?s tiny moonlets, which subtly warp the giant planet?s rings; the pockmarked moon Mimas, which bears an uncanny resemblance to the Star Wars Death Star; and the two-toned satellite Iapetus, which has one bright hemisphere and one dark one.

The film?s source material is publicly available?Cassini is a taxpayer-funded mission, and its images are distributed freely. The mission, which has captivated scientists and citizens alike, is planetary exploration at its best?a perfect example of why NASA must protect its imperiled planetary science programs, as we argued in an editorial last year.

Sound Waves Levitate and Move Objects

A new approach to contact-free manipulation could be used to combine lab samples while also preventing contamination

Water droplets, coffee granules, fragments of polystyrene and even a toothpick are among the items that have been flying around in a Swiss laboratory lately ? all of them kept in the air by sound waves. The device that achieves this acoustic levitation is the first to be capable of handling several objects simultaneously. It is described today in the Proceedings of the National Academy of Sciences.

Typically, levitation techniques make use of electromagnetism; magnetic forces have even been used to levitate frogs. It has long been known that sound waves could counter gravity, too, but so far the method has lacked practical application because it could do little more than keep an object in place.

To also move and manipulate levitating objects, Dimos Poulikakos, a mechanical engineer at the Swiss Federal Institute of Technology (ETH) in Zurich, and his colleagues built sound-making platforms using piezoelectric crystals, which shrink or stretch depending on the voltage applied to them. Each platform is the size of a pinky nail.

The platforms emit sound waves which move upward until they reach surface lying above, where they bounce back. When the downward-moving reflected waves overlap with the upward-moving source waves, the two ?cancel out? in the middle, at so-called node points. Objects placed there remain stuck in place because of the pressure of sound waves coming from both directions.

By adjusting the position of the nodes, the researchers can tow the objects between platforms. The platforms can be arranged in different ways to adapt to various experiments. In one demonstration involving a T-shaped array of platforms, the researchers joined two droplets introduced at separate locations then deposited the combined droplet at a third location.

Hands-free reactions
The system could be used to combine chemical reactants without the contamination that can result from contact with the surface of a container. Sound waves are already used in the pharmaceutical industry to obtain accurate results during drug screening. Yet Poulikakos?s method is the first to offer the possibility of precisely controlling several items simultaneously.

Poulikakos suggests that the system could be used to safely try out hazardous chemical reactions. ?We had fun demonstrating the idea by colliding a lump of sodium with some water, which is obviously an aggressive reaction,? he says.

Peter Christianen, a physicist who works on electromagnetic levitation at Radboud University in Nijmegen, the Netherlands, says that he?s impressed with the invention. ?I really like it; this is a very versatile platform ? almost anything you want to manipulate, you can.?

APNewsBreak: Ex-Mont. governor rejects Senate bid

HELENA, Mont. (AP) ? Popular former Gov. Brian Schweitzer said Saturday morning that he will not run for Montana's open U.S. Senate seat in 2014, an announcement that complicates Democratic efforts to retain their majority in next year's elections.

Schweitzer told The Associated Press that he doesn't want to leave Montana and go to Washington, D.C.

He had been considered the Democrats best candidate for holding onto the seat being vacated by U.S. Sen. Max Baucus next year. Schweitzer said he felt compelled to consider the race only because many in his party said they needed him to run.

"I love Montana. I want to be here. There are all kinds of people that think I ought to be in the United States Senate," Schweitzer said. "I never wanted to be in the United States Senate. I kicked the tires. I walked to the edge and looked over."

But ultimately, he said, "people need to know I am not running for the United States Senate."

The former governor was recently elected board chairman of Stillwater Mining Co., Montana's largest publicly traded company and said he is enjoying his life.

"I have responsibilities here in Montana, my family first. I have taken on a new life at the Stillwater mine. I owe it to the 1,670 people who work at the Stillwater mine that we continue to manage it and make it the best place to work in Montana," Schweitzer said. "This is my home, not Washington, D.C."

Schweitzer said recent criticism over politically active nonprofits connected to him had no bearing on the decision and said such criticism isn't new.

"This isn't my first rodeo," Schweitzer said.

Montana's open Senate seat is one of several being targeted by Republicans who hope to regain Senate control in the 2014 elections. Republicans need to pick up six seats to win back the majority and enjoy several advantages: the GOP is defending fewer incumbents than Democrats and could benefit from the fact that the party controlling the White House usually loses seats during the midterm election of a second-term president.

Democrats need to defend 21 seats, including seven in largely rural states that Republican Mitt Romney carried in 2012. Republicans hope to unseat four key incumbents: Mark Pryor of Arkansas, Mark Begich of Alaska, Kay Hagan of North Carolina and Mary Landrieu of Louisiana.

The brash, jeans-wearing Schweitzer last year told the AP: "I am not goofy enough to be in the House, and I'm not senile enough to be in the Senate."

The 57-year-old Democrat left office in January after eight years in office with high approval ratings, but he wasn't able to run again because of term limits. The unconventional governor, who easily won re-election in 2008, always displayed a feel for tapping into Montana's conservative-leaning yet libertarian politics.

In Helena, his heavy-handed style proved adept at largely getting his way with the state budget despite fostering a confrontational and sour relationship with majority Republicans. He often touted the state's surpluses at a time when many others were floundering.

The outspoken governor never missed an opportunity to leave a larger-than-life impression. He once stormed New York's Times Square with a bullhorn handing out Montana-made promotional trinkets from a semi-truck.

But Schweitzer said he is enjoying pursuits other than politics, with a new lake house and a small ranch in the mountains.

"I don't want a job where I have to wear a suit, and my dog isn't welcome," he said.

Other Democrats who expressed an interest in running, including State Auditor Monica Lindeen and schools Superintendent Denise Juneau, had been waiting on Schweitzer's decision.

The announcement surprised a Democratic Party that was meeting Saturday in Lewistown for its annual convention, and attention quickly turned to other potential candidates.

"Democrats were ready to get behind him in a bid for U.S. Senate," said Juneau. "Since his announcement, I have been receiving encouragement to run, and I plan to give careful thought to that decision."

State Sen. Kendall Van Dyk of Billings, said he understood the decision to spurn a dysfunctional Congress. "He chose Montana trout over the rattlesnakes," Van Dyk said.

However, he added, Schweitzer "has done tremendous things for the state, and any Democrat will tell you he has done tremendous things for the party. Montana needs Brian Schweitzer. And I believe this isn't the last we have heard of him."

Republicans are hopeful that freshman U.S. Rep. Steve Daines will run for the open seat. Some Republicans are also advocating former Montana Gov. Marc Racicot, who served from 1993 to 2001 and later chaired the Republican National Committee.

Daines said Saturday that he will continue to consider the race.

"My focus is fixed on serving the people of Montana and doing the job they sent me to do," he said in a statement. "I will continue to give this decision the consideration it deserves, and am still taking time to talk with my family and the people of Montana about how I can best be of service to our state."

As Schweitzer was mulling his options, the Montana Republican Party circulated a 2010 Internal Revenue Service form that showed a politically active nonprofit group called The Council for a Sustainable America used the same Helena post office box used for Schweitzer's 2008 re-election campaign and was signed by David Gallik, the state commissioner of political practices appointed by Schweitzer at the time.

The Council for a Sustainable America spent about $60,000 on politics in 2010, but it did not say in which races.

Schweitzer adviser Franklin Hall said at the time the nonprofit was never used for Montana politics or to aid Schweitzer.

Baucus, 71, announced in April that he was retiring. He was elected to the Senate in 1978 after serving two terms in the House. Baucus, who still controls a healthy campaign war chest, promised Democrats on Saturday he will continue helping them with 2014 elections.

"Brian was a great governor and there's no question he would have made an excellent candidate," Baucus said in a statement. "But we still have a wide field of qualified Montana Democrats who can run and win this seat."
