The hundreds of volcanoes on Jupiter's moon Io aren't where they're supposed to be, scientists say.

Io's major volcanic activity is concentrated 30 to 60 degrees farther east than models of its internal heat profile predict, a recent study reports, suggesting that the exotic,?volcanic Jupiter moon Io is even more mysterious than researchers had previously thought.

"The unexpected eastward offset of the volcano locations is a clue that something is missing in our understanding of Io," study lead author Christopher Hamilton, of the University of Maryland, said in a statement. "In a way, that's our most important result. Our understanding of tidal heat production and its relationship to surface volcanism is incomplete."

Io is the most volcanic body in the solar system, boasting activity 25 times that of Earth. Some of Io's volcanoes blast plumes of sulfur and other material 250 miles (400 kilometers) above the moon, which is completely resurfaced every million years or so. On Thursday (April 4), NASA released a video of Io's volcano plumes based on five images snapped by the agency's Pluto-bound New Horizons spacecraft in March 2007. ?[Amazing Photos of Io by NASA Spacecraft]

This intense activity is ultimately generated by gravitational tugs from Jupiter, with an assist from the nearby moons Europa and Ganymede.

Io completes two orbits for every one that Europa makes, and four for every one of Ganymede's laps. As a result of this regular timing, Europa and Ganymede have pulled the orbit of Io into an oval, with explosive consequences for the 2,260-mile-wide (3,640 km) moon.

As Io moves closer to Jupiter, the planet's powerful gravity pulls hard on the moon, deforming it. This force decreases as Io retreats, and the moon bounces back. This cycle of flexing creates friction in Io's interior, which in turn generates enormous amounts of volcano-driving tidal heat.

Common sense suggests that Io's volcanoes would be located above the spots with the most dramatic internal heating. But Hamilton and his colleagues found that the volcanoes are significantly farther to the east than expected.

They reached this surprising conclusion after studying data gathered by several ground-based telescopes and a number of spacecraft, including NASA's Voyager and Galileo probes, then comparing this information to a detailed geologic map of Io that scientists put together last year.

What's causing the disconnect between expected and observed volcano locations remains a mystery. It's possible that Io is rotating faster that scientists think, researchers said. Or models of Io's tidal heating may be missing some components, such as the complications caused by an underground magma ocean.

"Our analysis supports a global subsurface magma ocean scenario as one possible explanation for the offset between predicted and observed volcano locations on Io," Hamilton said. "However, Io's magma ocean would not be like the oceans on Earth. Instead of being a completely fluid layer, Io's magma ocean would probably be more like a sponge with at least 20 percent silicate melt within a matrix of slowly deformable rock."

Learning more about how Io's tidal heating works could shed light on the ability of other moons in the solar system to support life, researchers said. Tidal heating is thought to be the force making subsurface oceans of liquid water possible on frigid, ice-covered satellites, such as Europa and Saturn's moon Enceladus.

The study was publised in January in the journal Earth and Planetary Science Letters.

OSLO, Norway (AP) ? The family of a prominent Parisian art dealer is demanding that a Norwegian museum return an Henri Matisse painting seized by Nazis under the direction of Hermann Goering, in the latest dispute over art stolen from Jews during World War II.

The painting at the center of the dispute, Matisse's 1937 "Blue Dress in a Yellow Armchair," depicts a woman sitting in a living room. It has been among the highlights of the Henie Onstad Art Center near Oslo since the museum was established in 1968 through a donation by wealthy art collector Niels Onstad and his wife, Olympic figure-skating champion Sonja Henie.

Museum Director Tone Hansen said it had been unaware the painting was stolen by the Nazis until it was notified in 2012 by the London-based Art Loss Register, which tracks lost and stolen paintings.

She said Onstad bought the painting in "good faith" from the Galerie Henri Benezit in Paris in 1950. The Benezit gallery "has no record of collaborating with the Nazis, as many galleries did," she said in an interview.

Although the war ended almost 70 years ago, disputes over looted art have become increasingly common in recent years, in part because many records were lost, and in part because an international accord on returning such art was only struck in 1998.

But the case of the Matisse is somewhat different in that its former owner, Paul Rosenberg, was one of the most prominent art dealers in Paris before the war, which he survived by fleeing to New York. Art Loss Register Director Chris Marinello said the records in this case are unusually clear.

According to a biography published by New York's Museum of Modern Art, Rosenberg was one of the preeminent modern art dealers of his day, and personal friends with Picasso and Matisse, among others.

Art Registry documents show he purchased "Blue Dress" directly from the painter, having noted the purchase in 1937 and put it on display in the same year, Marinello said. After the war, Rosenberg re-established his business and sought to recover more than 400 works that had been taken by the Nazis.

Marinello showed The Associated Press documents that name the piece now on display in Norway as among those missing after the war.

He slammed the Henie Onstad art museum for "stonewalling."

"The evidence is overwhelming. They just don't want to resolve this," he said.

Paul Rosenberg died in 1959. His family has remained prominent, as his son Alexandre was a war hero and later began his own art dealership.

Among surviving family descendants are Anne Sinclair, the French journalist and ex-wife of former International Monetary Fund chief Dominique Strauss Kahn.

Another granddaughter, American lawyer Marianne Rosenberg, said Friday she didn't wish to antagonize the museum, but hoped that it would come to realize that it is wrong in every sense of the term.

The paintings seized from Paul Rosenberg and other Jewish victims of Nazi aggression were taken "under difficult conditions, in a cruel and unfair situation," she said in a telephone interview from her office in New York. "We honor my grandfather Paul's memory ... by doing what he would have done: we wish to recover that which we consider ours."

The lawyer representing the museum, Kyre Eggen, said it was significant that Onstad didn't know where the painting came from.

Under Norwegian law, if a person has had an item in good faith for more than 10 years, that person becomes the rightful owner, he said.

That argument runs against the Washington Conference Principles on Nazi-Confiscated Art, to which Norway is a party. The principles say that owners of looted art should take into account the difficulty that Jewish war survivors faced in reclaiming lost property after the Holocaust, and that owners of looted art should in all cases seek a fast and fair solution.

The Seattle Art Museum returned a Matisse to the Rosenberg family in 1999, after initially making similar arguments.

Eggen also argued that it is possible Rosenberg sold the painting himself between 1946 and 1950.

But Marianne Rosenberg rejected that possibility. Art Loss Register documents show Paul Rosenberg notifying French authorities the piece was missing in 1946, and his family again listing it as among missing pieces it was seeking in 1958.

"The Rosenberg family has since the end of the war assiduously and continuously sought the recovery of the paintings it lost," she said. "We have never sought to recover paintings not lost."

PISCATAWAY, N.J. (AP) ? Tim Pernetti resigned as Rutgers athletic director on Friday, two days after the basketball coach he hired was dismissed for abusive behavior during practices ? actions that prompted nationwide outrage once a video went public.

In a letter of resignation sent to university president Robert Barchi, Pernetti said he hoped that his tenure at Rutgers "will not be judged by this one incident."

When he first saw the video of Rice pushing, shoving and throwing balls at players in November, Pernetti said he wanted to fire him on the spot. However, he said the consensus among school officials at the time was the actions didn't call for dismissal.

The video was broadcast Tuesday on ESPN, showing numerous clips of Rice at practice firing basketballs at players, grabbing them by their jerseys and yelling obscenities in addition to gay slurs.

At a campus news conference Friday, Barchi said he first saw the video this week, but was aware it existed in late November. He said Pernetti gave him a summary of what was on the Rice video at the time.

"This was a failure of process. I regret that I did not ask to see this video when Tim first told me of its existence," Barchi said. "I want to apologize to the entire Rutgers community for the negative impact that this situation has had on Rutgers.

"I also apologize to the LGBTQ community and all of us who share their values for the homophobic slurs shown on that video. I personally know how hurtful that language can be."

Based on the summary he received from Pernetti, Barchi said he "agreed with and supported his recommendation to suspend, rather than fire, coach Rice at that time. It was not until Tuesday evening of this week, when I watched the video, that I had the opportunity to witness personally for the first time what Tim had seen last fall."

"I was deeply disturbed by the behavior that the video revealed, which was much more abusive and pervasive than I had understood it to be. As Tim acknowledged on Wednesday, his decision to rehabilitate, rather than fire, coach Rice was wrong."

Also resigning Friday was John B. Wolf, Rutgers' interim senior vice president and general counsel who is believed to have recommended against firing Rice in December.

Pernetti said in his resignation letter to Barchi that he has "spent a great deal of time reflecting on the events which led to today. As you know, my first instincts when I saw the videotape of Coach Rice's behavior was to fire him immediately. However, Rutgers decided to follow a process involving university lawyers, human resources professionals, and outside counsel.

"Following review of the independent investigative report, the consensus was that university policy would not justify dismissal. I have admitted my role in, and regret for, that decision, and wish that I had the opportunity to go back and override it for the sake of everyone involved," it said.

Pernetti was given the video by a former employee, Eric Murdock. With Barchi's approval, he suspended Rice for three games, fined and docked him pay totaling $75,000 and ordered him to attend anger management classes.

The 42-year-old Pernetti is a Rutgers graduate who played tight end for the Scarlet Knights from 1989-93.

Before Pernetti's resignation, there was an outcry from Rutgers faculty and state legislators not only for his ouster but for Barchi's as well.

By Friday morning, nearly 3,000 people had joined a Facebook site calling for the university to keep him, several accusing the media and politicians of a witch hunt. Former Rutgers football players including Baltimore Ravens running back Ray Rice and Eric LeGrand, who was paralyzed during a game in 2010, were among those campaigning for Pernetti.

On Thursday, assistant coach Jimmy Martelli resigned.

Pernetti's finest hour may have been when he helped in the school's move to the Big Ten Conference, which means millions in additional revenue by way of television contracts and more national exposure, especially in football. The move, which becomes official in 2014, should provide a big boost to the program in recruiting and season ticket sales. The Scarlet Knights will continue to play next season in the Big East.

Pernetti's first major move as athletic director came in May 2010, when he hired the volatile Rice away from Robert Morris, which he took to two NCAA tournament appearances.

"He convinced me he understood his reputation, but he also understood where the line was," Pernetti said, referring to Rice. "I made clear to him if he crossed the line he would be held accountable."

The move might have been too soon for a coach like Rice, and clearly Pernetti took a serious risk. After all, most Big East coaches do not land there immediately after stops in the Northeast Conference, but Rutgers and Pernetti looked at Rice and saw the man who could turn the perennially underachieving program around.

It never happened. Rice went 44-51 in three years and posted a 16-38 mark in the Big East after going 73-31 in three seasons at Robert Morris. The Scarlet Knights went 15-16 this season, including 5-13 in the league, and questions about Rice's status ? based on wins and losses alone ? began to surface.

But Pernetti again made a questionable decision. Given what he knew about the video, and taking Rice's record into consideration, he still gave the coach a public endorsement at season's end.

"Of course he's coming back," Pernetti said at the time. "It's been an interesting year to say the least, and while I think in one case some of the progress ? and there's been a lot of progress ? doesn't show, and that's in the win-loss column. I would like it to show there. I think everyone in the program would. But you can definitely see us getting better."

Three years ago, the feds created an online portal at HealthCare.gov to help folks, especially the uninsured, navigate the muddy and mushrooming marketplace of health-care plan options.

While the site is seeing successes, some bugs must be worked out so consumers can obtain complete and accurate information about benefits and prices, according to a report released this week by the inspector general for the U.S. Department for Health and Human Services.

The office found these gaps, among others:

* Insurance products and plans showcased on the website?s ?plan finder? aren?t always available for sale. Some offerings weren?t even recognized by representatives of insurance operators contacted by the inspector general. If the products were available, almost 20 percent of the data displayed didn?t match details provided by insurance operators.

* While most private insurers reported detailed benefit data to the plan finder, as required under the Affordable Care Act, the U.S. Centers for Medicare & Medicaid Services didn?t follow up with insurers that failed to furnish the information. The agency also still hasn?t identified the full universe of providers required to report data.

CMS officials generally agreed with the report, the inspector general said, and are taking taking steps to close the gaps.
