Video: Senator?s private plane trips prompt ethics probe



>> federal agents are culling through dozens of boxes from a from nent florida eye doctor and now scrutiny falling on a top ranking democratic senator. justice correspondent pete williams has the story. good morning.

>> good morning. federal officials are declining to say exactly what's behind the search but the doctor is well-known is south florida . he's been an active political contributor and friend of senator robert menendez , the subject of an ethics complaint.

>> reporter: in florida , federal agents hauled away boxes of material tuesday night and witnessed from the office of a west palm beach eye doctor . he and members of his family are big political contributors. records show they've given more than $33,000 in the past 15 years to u.s. senator robert men menendez .

>> this hearing of the senate foreign relations committee --

>> reporter: he just took over as chairman of the senate florida relations committee. they appeared at a gala chaired by milgen. the senate ethics committee has received a complaint from a new jersey republican official who complained menendez got rides on a private plane to the dominican republic and elsewhere without disclosing them.

>> senator went on flights to dominican republic and flights to puerto rico , et cetera from this doctor down in florida on his private jet , which he had failed to report.

>> reporter: in a statement, saturday menendez called the doctor a friend and political supporter many years and took three trips on that plane but paid for and reported them properly. but his staff said he wrote a check two weeks ago three weeks after the ethics complaint was made to reimburse the doctor $58,000 for two trips in 2010 and the senator refers to a series of claims made on conservative websites saying he met with prostitutes while in the dominican republic . those allegations, they say are manufactured, politically motivated and false, based on a series of anonymous e-mails that first surfaced last april sent to a political watchdog group in washington called crew. but when the tipster repeatedly declined to talk on the phone or agree to a meeting, the group turned the messages to the fbi.

>> it turns out he has no real interest coming forward and making sure this matter can be investigated as a law enforcement issue. it seems he's much more interested seeing it brought to light as a big scandal.

>> reporter: as for the search in florida , federal officials say agents from the department of human services were involved meaning they may be looking into allegations of health care fraud.

Hagel emerges with solid Dem support for Pentagon

WASHINGTON (AP) ? Bruised and battered, Chuck Hagel emerged from his grueling confirmation hearing with solid Democratic support for his nomination to be President Barack Obama's next defense secretary and increasing Republican opposition to a former GOP colleague.

Mathematically, Hagel has the edge as he looks to succeed Defense Secretary Leon Panetta as the nation's 24th Pentagon chief, with Democrats holding a 14-12 advantage on the Senate Armed Services Committee.

That vote, which could come as early as next Thursday, looks increasingly like a straight party-line count as committee member and Republican Sen. Roy Blunt said Friday he will oppose the nomination.

"Senator Hagel's answers before the committee were simply too inconsistent, particularly as they related to Iran and Israel," said the Missouri lawmaker. "The idea that we can contain a nuclear Iran and his view that we should not have unilateral sanctions are just wrong and are too dangerous for us to try."

In fact, Hagel corrected his statement about containment of Iran and said all options, including military action, should be on the table to stop Iran from acquiring a nuclear weapon.

While Blunt announced his opposition, he signaled he would not support any effort to block the nomination, a looming question as Democrats have the votes to confirm Hagel in the full Senate but would need five GOP senators to end a filibuster.

Senate Armed Services Committee Chairman Carl Levin, D-Mich., expressed optimism about Hagel's prospects after nearly eight hours of testimony Thursday.

"I think his answers were honest and forthright and he did very well," Levin told reporters. "I hope that there will be some, who maybe were skeptical but who are undecided before this hearing, will maybe now look at him in a more favorable light. But I think there are a whole lot of folks who basically decided before the hearing that they were going to vote against him."

Hagel struggled at times as GOP senators hammered him on issues ranging from his support for Israel, opposition to Iran, stand on Hamas and Hezbollah and his backing for a group that advocates the elimination of nuclear weapons.

They repeatedly pressed him on past statements, votes and even letters he declined to sign. Refusing to show any frustration or anger, Hagel defended his record.

The former two-term Republican senator from Nebraska described his views as mainstream and closely aligned with those of Obama, the Democrat who nominated him. But several GOP members of the committee sought to portray him as radical and unsteady. Sen. Deb Fischer, R-Neb., called his ideas "extreme" and "far to the left" of Obama.

Hagel said he believes America "must engage ? not retreat ? in the world" and insisted that his record is consistent on that point.

He pointed to Iran and its nuclear ambitions as an example of an urgent national security threat that should be addressed first by attempting to establish dialogue with Iranian rulers, although he said he would not rule out using military force.

"I think we're always on higher ground in every way ? international law, domestic law, people of the world, people of the region to be with us on this ? if we have ... gone through every possibility to resolve this in a responsible, peaceful way, rather than going to war," he said.

He pushed back on the notion ? first raised by one of his harshest Republican critics, Sen. James Inhofe of Oklahoma ? that he favors a policy of appeasement.

"I think engagement is clearly in our interest," Hagel told Sen. Saxby Chambliss, R-Ga., who denounced the idea of negotiating with a "terrorist state."

"That's not negotiation," Hagel said. "Engagement is not appeasement. Engagement is not surrender."

The nominee's fiercest exchange came with Sen. John McCain, R-Ariz., a fellow Vietnam veteran and onetime close friend. Politics and Hagel's evolving opposition to the Iraq war caused a split between the two men that was on full display.

McCain suggested that Hagel and his critics were not quibbling over small matters.

"They are not reasonable people disagreeing; they are fundamental disagreements. Our concerns pertain to the quality of your professional judgment and your worldview on critical areas of national security," he said.

McCain pressed Hagel on whether he was right or wrong about his opposition to President George W. Bush's decision to send an extra 30,000 troops to Iraq in 2007 at a point when the war seemed in danger of being lost. Hagel, who voted to authorize military force in Iraq, later opposed the conflict, comparing it to Vietnam and arguing that it shifted the focus from Afghanistan.

"Were you right? Were you correct in your assessment?" McCain asked.

"I would defer to the judgment of history to sort that out," Hagel said as the two men talked over each other.

"The committee deserves your judgment as to whether you were right or wrong about the surge," McCain insisted.

Unable to elicit a simple response, McCain said the record should show that Hagel refused to answer. And he made it clear that he would have the final word ? with his vote, which he said would be influenced by Hagel's refusal to answer yes or no.

"I think history has already made a judgment about the surge, sir, and you're on the wrong side of it," he said.

Responding to criticism from outside GOP-leaning groups, Hagel repeated his regrets about using the term "Jewish lobby" to refer to pro-Israel groups. He said he should have used another term and should not have said those groups have intimidated members of the Senate into favoring actions contrary to U.S. interests.

"I'm sorry and I regret it," Hagel said. "On the use of 'intimidation,' I should have used 'influence,' I think would have been more appropriate."

At one point, Hagel mistakenly said the Obama policy toward Iran is "containment" even though the former senator has said all options, including military force, should be on the table. He was handed a note and corrected himself.

Hagel, 66, would be the lone Republican in Obama's Cabinet, the first Vietnam veteran to be defense secretary and the first enlisted man to take the post.

Liftoff! NASA Launches Next-Generation Relay Satellite into Space

This story was updated at 10:46 p.m. ET.

A next-generation NASA relay satellite was launched into orbit Wednesday (Jan. 30) on a mission to upgrade a vital communications network linking the space agency to its spacecraft orbiting the Earth.

The U.S. space agency's first launch of 2013, the new Tracking and Data Relay Satellite K (TDRS-K for short) soared spaceward atop a United Launch Alliance Atlas 5 rocket from Cape Canaveral Air Force Station in Florida at 8:48 p.m. EST (0148 Jan. 31 GMT).

"We have a customer that's quite thrilled right now to have a healthy satellite on orbit," Tim Dunn the TDRS-K flight director said in a NASA TV interview after the launch.

The TDRS-K satellite is bound for an orbit 22,300 miles (35,888 kilometers) above Earth, where it will join a constellation of five other satellites currently in orbit to help NASA and other space agencies stay in touch with orbiting spacecraft.

NASA's TDRS communications network began in 1983 and has not received an upgrade since 2002, when the space agency launched its 10th TDRS satellite. Five satellites are currently in use today, with the TDRS-K launch adding one more that number, mission managers said. [Launch Photos: NASA's TDRS-K Satellite Blasts Off ]

The TDRS-K satellite is expected to spend at least 15 years, but agency officials expect that the satellite will exceed its projected life-expectancy. Many of the network's satellites have outlived their expected mission lifetimes, ?said Jeffrey Gramling, NASA's TDRS project manager.

But that does not mean that TDRS-K is unnecessary. One of the satellites currently in active service is slated be retired in the next few months, and other satellites in the aging network are getting older, said Badri Younes, a scientist in NASA's Space Communications and Navigation office.

The satellite launched today was the first of three new satellites expected to enter service between now and 2015 that should further bolster the network. The TDRS-K mission costs between $350 million and $400 million, not including the price of its rocket.

The TDRS-K satellite is 26 feet long (8 meters) and weighs about 7,615 pounds (3,454 kilograms). It was expected to separate from its Atlas 5 rocket one hour and 46 minutes after liftoff, with a Centaur upper stage rocket engine slated to carry it the rest of the way to its geosynchronous orbit.

The satellite is expected to deploy its solar arrays and giant antennas about 11 days after launch, according to a mission description. ?

NASA's TDRS satellite network is part of the larger "Space Network" used keep space agencies on the ground in constant communication with orbiting spacecraft. The International Space Station sends all of its data and messages through the network using the TDRS satellites. The rocket that sent TDRS-K into orbit even uses the space network to beam down data, Vernon Thorp, a program manager with NASA said.

TDRS-K is now entering into a three month period of testing and calibrations, but once those tests are complete the NASA research team will decide if the satellite is ready for service.?

Confirmed: How plant communities endure stress

Thursday, January 31, 2013

Ecology is rife with predation, competition, and other dramatic "negative interactions," but those alone do not determine the course life on Earth. Organisms sometimes benefit each other, too, and according to the Stress Gradient Hypothesis, their "positive interactions" become measurably more influential when ecosystems become threatened by conditions such as drought. Ecologists have argued about the hypothesis ever since Brown University ecologist Mark Bertness co-proposed it in 1994; Bertness says a large new global meta-analysis he co-authored in Ecology Letters definitively shows that it is true.

The evidence, principally analyzed by former Brown visiting graduate student Qiang He of Shanghai Jiao Tong University in China, comes from 206 studies of 727 shifts of plant interactions amid varying degrees, or gradients, of stress on six continents. Examining the data from each paper and contacting original authors when necessary, He determined the overall trends across the many experiments.

In the vast majority of studies, as stress increased, the significance of interactions shifted toward mutual support in that positive interactions, such as those that promoted neighbors' survival, strengthened in influence, and negative interactions, such as those that hindered neighbors' growth, weakened. In some studies, stress did not change interactions, but negative interactions never increased as stress did, no matter what kinds of plants were involved, what kinds of conditions they were under, or where they were.

"Our results show that plant interactions generally change with increased environmental stress and always in the direction of an outright shift to facilitation (typical for survival responses) or a reduction in competition (typical from growth responses)," the authors wrote in the paper published online. "We never observed an increase in competition at higher stress. These findings were consistent across fitness measures, stress types, growth forms, life histories, origins, climatic zones, ecosystems and methodologies."

Analyses of studies of grasses, trees, and shrubs, for example, found that despite the obvious differences among these plant types, they all shifted toward less negative or more positive interactions.

"Typically, highly competitive species [e.g., grasses] have decreased competitive or neutral effects at high stress, whereas less competitive species [e.g., trees] have strong facilitative effects at high stress," the authors wrote.

Overall, the researchers found, studies with observations of greater degrees of stress increase ? "longer" stress gradients ? also observed greater degrees of shift toward positive interactions.

The hypothesis and the importance of positive interactions in ecology began to occur to Bertness in the 1970s and 1980s. As a junior faculty member at Brown, along the shores of Rhode Island, he noticed that seaweeds and barnacles would never survive the heat stress above the tides in isolation. They could only persist in groups, suggesting that with stress, organisms were better off together ? despite their competition ? than apart.

It's the same reason why sparsely planted gardens wilt in hot, dry conditions while more densely planted gardens survive. Mutually beneficial soil shading becomes more important than competition for that soil moisture when it becomes scarce.

Bertness published the Stress Gradient Hypothesis in Trends in Ecological Evolution with Ray Callaway, then a graduate student at the University of California?Santa Barbara. Callaway is now a professor at the University of Montana.

A shift in research?

Nearly two decades later with so much evidence now assembled, Bertness said, ecologists should feel confident enough in the Stress Gradient Hypothesis to employ it as a "rule of thumb." Rather than continuing to debate whether the hypothesis is valid, he said, researchers could now focus on crafting experiments to probe how much predictive value the hypothesis has and test its applications to conservation biology.

The hypothesis suggests, for example, that marine ecosystem managers who want to help tropical fish should focus on sustaining foundational species in the ecosystem, such as corals. With the ecosystem's foundation shored up the natural tendency among species toward greater positive interactions under stress should allow the fish to weather stress better.

"We're no longer in the casual, earlier stages of ecology," Bertness said. "In our lifetimes we're watching Caribbean coral reefs die, kelp forests die, and salt marshes and sea grass beds being decimated. We need to figure this stuff out quickly. These are no longer intellectual arguments without consequence."

In other words, with nature under stress, Bertness hopes that He's efforts to pull together the available data will lead ecologists to pull together so that they can apply the guidance the hypothesis provides.

Kermadec Trench: The Cosmopolitan Rattail

Overnight, we sampled depths between 3000 and 3500 meters along a gradual slope. Both landers worked well, and provided some excellent footage of fish attracted to the bait. The bait, by the way, is jack mackerel, an oily fish which creates a good ?odor plume? (basically a strong smell) that is very effective for the fish, but baiting the fish and amphipod traps is not such a popular task on deck!

Back to the landers ? the photographs showed a frequent visitor to the bait was a species of macrourid rattail. The fish were at times quite aggressive in chewing into the bait, although the behavior of most fish was reasonably casual, some even ignoring the bait and swimming on past. Rattails are often filmed with their heads down in prey-searching mode near the seafloor, and so it was interesting to see these fish with their heads up almost appearing to sniff the water to follow the odor trail.

The fish trap was eagerly anticipated, although there was initial disappointment as it came aboard with only a single fish. However, the fish was the rattail we had seen in the photographs, and it confirmed the species to be the ?cosmopolitan rattail? Coryphaenoides armatus. This is a very common and widespread species throughout the world?s oceans at abyssal depths (hence the name), but it has rarely been recorded from New Zealand waters as most research and commercial fishing occurs shallower than the depth range of these rattails.

Interestingly, the species was first discovered off the west coast of New Zealand?s North Island during deep trawling by HMS Challenger back in 1874, but those specimens were taken back to England and so the fish we caught will be the first specimen of the species from inside the New Zealand exclusive economic zone to be held at the National Fish Collection at The Museum of New Zealand (Te Papa Tongarewa). That made the catch both exciting and scientifically significant.

As we go deeper in coming days, we expect to come across more new and interesting fish. As fish densities are unlikely to be high, we should perhaps expect small catches in the trap?.we will let you know how we get on at 4000 meters tomorrow.
