(AP) ? Republican vice presidential nominee Paul Ryan is courting Cuban-American voters with promises to be tougher on the Castro government than President Barack Obama.

Ryan campaigned Saturday morning in Miami's Little Havana neighborhood. He'll hold a town hall in the afternoon at the University of Central Florida in Orlando.

Former Florida Gov. Jeb Bush, Miami's Cuban-American congressional representatives and Republican presidential nominee Mitt Romney's son Craig touted Ryan's credentials in English and Spanish for the breakfast crowd.

Ryan said he and Romney would help get Latinos back to work. He also said America offered a better life to immigrants seeking freedom and prosperity. Cubans benefit from the so-called wet foot, dry foot policy that provides those who literally step on U.S. soil with temporary visas and a path to legal citizenship.

Dawn Sees Hydrated Minerals on Giant Asteroid

ScienceDaily (Sep. 20, 2012) ? NASA's Dawn spacecraft has revealed that the giant asteroid Vesta has its own version of ring around the collar. Two new papers based on observations from the low-altitude mapping orbit of the Dawn mission show that volatile, or easily evaporated materials, have colored Vesta's surface in a broad swath around its equator.

Pothole-like features mark some of the asteroid's surface where the volatiles, likely water, released from hydrated minerals boiled off. While Dawn did not find actual water ice at Vesta, there are signs of hydrated minerals delivered by meteorites and dust evident in the giant asteroid's chemistry and geology. The findings appear today in the journal Science.

One paper, led by Thomas Prettyman, the lead scientist for Dawn's gamma ray and neutron detector (GRaND) at the Planetary Science Institute in Tucson, Ariz., describes how the instrument found signatures of hydrogen, likely in the form of hydroxyl or water bound to minerals in Vesta's surface.

"The source of the hydrogen within Vesta's surface appears to be hydrated minerals delivered by carbon-rich space rocks that collided with Vesta at speeds slow enough to preserve their volatile content," said Prettyman.

A complementary paper, led by Brett Denevi, a Dawn participating scientist based at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., describes the presence of pitted terrain created by the release of the volatiles.

Vesta is the second most massive member of the main asteroid belt. The orbit at which these data were obtained averaged about 130 miles (210 kilometers) above the surface. Dawn left Vesta earlier this month, on Sept. 4 PDT (Sept. 5 EDT), and is now on its way to its second target, the dwarf planet Ceres.

Scientists thought it might be possible for water ice to survive near the surface around the giant asteroid's poles. Unlike Earth's moon, however, Vesta has no permanently shadowed polar regions where ice might survive. The strongest signature for hydrogen in the latest data came from regions near the equator, where water ice is not stable.

In some cases, other space rocks crashed into these deposits later at high speed. The heat from the collisions converted the hydrogen bound to the minerals into water, which evaporated. The holes that were left as the water escaped stretch as much as 0.6 miles (1 kilometer) across and go down as deep as 700 feet (200 meters). Seen in images from Dawn's framing camera, this pitted terrain is best preserved in sections of Marcia crater.

"The pits look just like features seen on Mars, but while water was common on Mars, it was totally unexpected on Vesta in these high abundances," said Denevi. "These results provide evidence that not only were hydrated materials present, but they played an important role in shaping the asteroid's geology and the surface we see today."

GRaND's data are the first direct measurements describing the elemental composition of Vesta's surface. Dawn's elemental investigation by the instrument determined the ratios of iron to oxygen and iron to silicon in the surface materials. The new findings solidly confirm the connection between Vesta and a class of meteorites found on Earth called the Howardite, Eucrite and Diogenite meteorites, which have the same ratios for these elements. In addition, more volatile-rich fragments of other objects have been identified in these meteorites, which supports the idea that the volatile-rich material was deposited on Vesta.

The Dawn mission is managed by the Jet Propulsion Laboratory for NASA's Science Mission Directorate, Washington. It is a project of the Discovery Program managed by NASA's Marshall Space Flight Center, Huntsville, Ala. UCLA is responsible for overall mission science. Orbital Sciences Corporation of Dulles, Va., designed and built the Dawn spacecraft.

The framing cameras were developed and built under the leadership of the Max Planck Institute for Solar System Research, Katlenburg-Lindau, Germany, with contributions by the German Aerospace Center (DLR) Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering, Braunschweig. The framing camera project is funded by the Max Planck Society, DLR and NASA. The gamma ray and neutron detector instrument was built by Los Alamos National Laboratory, N.M., and is operated by the Planetary Science Institute, Tucson, Ariz.

JPL is a division of the California Institute of Technology, Pasadena.

Blood Tests Show Where Loggerhead Turtles Go

Every year, thousands of endangered loggerhead sea turtles crawl ashore at Florida's Archie Carr National Wildlife Refuge to lay eggs before dragging their leathery bodies back into the sea. But where they go after their trek isn't well-known.

Scientists can use GPS devices to record turtles' travels, but these geolocator tags are expensive, and may be lost if turtles die. A group of researchers has come up with a less expensive, easier way to find out where loggerheads voyage: testing their blood. A new study, published Sept. 20 in the journal PLoS ONE, found that this technique is just as accurate as using GPS tags.

The technique examines carbon isotopes in the turtles' blood, which come from the food the animals eat. Carbon has different isotopes, or variants, present in all living things, and the exact mix of isotopes varies by region; for example, the mixture in the mid-Atlantic is different from that of the Caribbean. By examining the mixture of carbon isotopes in the turtles' blood, scientists could determine the region to which the turtles migrated.

The study found that some turtles head for the water off the shores of Virginia and Delaware while others go to the Bahamas and the Gulf of Mexico. Some also stay nearby, off Florida's coasts. Previously, scientists thought that the majority of the loggerheads headed south, according to a release from the University of Central Florida.

"Think of these turtles as Florida tourists and snowbirds," Simona Ceriani, a University of Central Florida graduate student and study co-author, said in a statement. "They come and nest and then go back to lots of different places. And while we knew some went back north, we had no idea that this was a popular destination."

While there are efforts to protect the turtle nests on the beaches, protecting the foraging grounds of this endangered species is also important, the release noted. ?Many turtles die because they get tangled in fishing nets or encounter other dangers while out at sea.

"This research helps scientists and conservation managers identify key feeding areas for loggerhead turtles and helps direct policy and regulations that protect sea turtles in these specific areas," said Daniel R. Evans, a researcher at the Sea Turtle Conservancy and study co-author, in a statement.

The Archie Carr National Wildlife Refuge is home to the second-largest population of loggerheads in the world and to about one of every four nests those turtles lay in the United States. While populations of other turtles have increased in the refuge, loggerhead numbers there have declined for unknown reasons.

Sniping from within GOP adds to Romney's struggles

(AP) ? Mitt Romney struggled to steady his presidential campaign on Friday, buffeted by an outbreak of sniping by frustrated Republicans, fresh evidence of a slide in battleground state polls and President Barack Obama's accusation that he was writing off "half the country" in pursuit of the White House.

Republican running mate Paul Ryan drew boos at an AARP convention in New Orleans when he said Romney would repeal Obama's health care law, which closed a gap in coverage for seniors' prescription drugs. The Wisconsin congressman accused the administration of weakening Medicare and flinching from tough measures needed to stabilize Social Security's finances, adding that the president has "put his own job security over your retirement security."

Obama rebutted Ryan's charges point by point in a video appearance to the same audience. He said the Republican prescription for Medicare would mean "billions in new profits for insurance companies" and replacing guaranteed benefits with a voucher that would bring higher out of pocket costs for seniors.

Romney campaigned in Nevada as aides released a 2011 federal income tax return showing he and his wife, Ann, paid $1.94 million in federal taxes last year on income of $13.7 million. Their effective tax rate was 14.1 per cent, lower than many families pay because most of the couple's earnings come from investments.

The campaign also released a letter from Romney's doctor saying the 65-year-old former Massachusetts governor is healthy and physically up to the demands of the presidency.

Republicans tried to yank the campaign focus back to the economy.

"While President Obama and Democrats will try to distract voters, Mitt Romney and Paul Ryan are focused on fixing the economy, getting Americans back to work and ensuring a better future for our children and grandchildren," Sen. John McCain, the Republicans' 2008 presidential candidate, said in a statement.

But there seemed no letup in the bad political news for Romney, hit by a barrage of it since he was seen on videotape saying that his job as a candidate is not to worry about the 47 percent of Americans whom he said pay no income taxes and see themselves as victims.

Obama, for sure, was eager to keep the controversy alive. Campaigning in Woodbridge, Va., he defended himself against Romney's jabs in response to his own statement that change is impossible from the inside in Washington. "It can't happen if you write off half the nation before you even took office," he said.

According to Wall Street Journal/NBC News/Marist Poll surveys, the president has opened leads among likely voters of eight percentage points in Iowa, with 6 electoral votes, and margins of five percentage points each in Colorado (9 electoral votes) and Wisconsin (10.)

Earlier surveys published this week pointed to leads for Obama in both Virginia, with 13 electoral votes, and Ohio, with 18.

National polls have been far closer, including an AP-GfK survey this week that had it a statistical tie among likely voters. They have also suggested progress for Obama in terms of his handling of the economy, the No. 1 issue in the race.

Despite Romney's difficulties, recent soundings on employment have not been encouraging for the president's re-election. Newly released figures show joblessness ticked up in five swing states in August, fell in two and was unchanged in two others.

Romney's allies also point to a series of presidential debates beginning Oct. 3 as a chance to shake up the race.

But for now, Romney's troubles have sent shudders down ballot, where Republicans are in tough races that will settle the outcome for the struggle for control of the Senate this fall. Tommy Thompson, dropping in the polls in Wisconsin, said "the presidential thing is bound to have an impact on every election."

That produced a quick retort from John Sununu, a top Romney surrogate. "My good friend Tommy Thompson sounds like Barack Obama, blaming it on somebody else," he said on CNN.

But Thompson wasn't alone. Rep. Rick Berg, running for the Senate in a closer-than-expected race in North Dakota, became the latest in a string of Republican candidates to say they disagreed with Romney's 47 percent remarks.

Apart from his self-inflicted political wounds, Romney has been under pressure from fellow Republicans to draw clearer distinctions with Obama on the economy, and say more clearly what he would do to bring down the nation's 8.1 percent unemployment rate.

Asked to point to new policy proposals that Romney has made since early August, aides referred to one speech on energy independence and a set of remarks on veterans.

But he has generally been unwilling to flesh out his plans for balancing the budget or enacting tax reform, refusing, for example, to name a tax break he would eliminate except for a small one that subsidizes producers of wind power.

He criticized Obama's handling of anti-American demonstrations around U.S. embassies in the Middle East earlier in the month, but declined to say what approach he would have taken instead. And while he has repeatedly tagged Obama for not being more forceful in trying to arrange the downfall of Syrian President Bashar Assad, aides have refused for nearly a month to say whether the Republican challenger supports arming rebels fighting the regime.

Ryan provided no new policy details in his appearance before the AARP, although he renewed Romney's support for a gradual increase in the Social Security retirement age and slowing the growth of benefits for those at higher incomes. Republicans have yet to provide details.

He told seniors that Republicans "respect you enough to level with you," and said Obama's health care legislation had cut $716 billion out of Medicare over a decade and set up a board of unelected bureaucrats with authority to make future reductions so severe they could eventually jeopardize seniors' access to medical care.

"You know President Obama's slogan, right? Forward." he said, then added, mockingly, "Forward into a future where seniors are denied the care they earned because a bureaucrat decided it wasn't worth the money."

Obama answered via video hookup and a television commercial that began airing in Florida, Colorado and Iowa. It argued that under the Republican plan, seniors' health costs could go up by $6,400 a year.

Obama has said he would consider raising payroll taxes on upper-income wage earners to shore up the trust fund that pays for Social Security benefits. Workers currently pay a 4.2 percent tax on income up to $110,100 annually, although the rate is scheduled to revert to a previous 6.2 percent at the first of the year.

Squeeze light 'till it hurts' on a quantum scale: Researchers push the boundaries on ultra-precise measurement

ScienceDaily (Sep. 21, 2012) ? An international team of physicists has pushed the boundaries on ultra-precise measurement by harnessing quantum light waves in a new way.

It is one thing to be able to measure spectacularly small distances using "squeezed" light, but it is now possible to do this even while the target is moving around.

An Australian-Japanese research collaboration made the breakthrough in an experiment conducted at the University of Tokyo, the results of which have been published in an article, "Quantum-enhanced optical phase tracking" in the journal Science.

Leader of the international theoretical team Professor Howard Wiseman, from Griffith University's Centre for Quantum Dynamics (pictured), said this more precise technique for motion tracking will have many applications in a world which is constantly seeking smaller, better and faster technology.

"At the heart of all scientific endeavour is the necessity to be able to measure things precisely," Professor Wiseman said.

"Because the phase of a light beam changes whenever it passes through or bounces off an object, being able to measure that change is a very powerful tool."

"By using squeezed light we have broken the standard limits for precision phase tracking, making a fundamental contribution to science," he said. "But we have also shown that too much squeezing can actually hurt."

Dr Dominic Berry from Macquarie University has been collaborating with Professor Wiseman on the theory of this problem for many years.

"The key to this experiment has been to combine "phase squeezing" of light waves with feedback control to track a moving phase better than previously possible," Dr Berry said.

"Ultra-precise quantum-enhanced measurement has been done before, but only with very small phase changes. Now we have shown we can track large phase changes as well," he said.

Professor Elanor Huntington from UNSW Canberra, who directed the Australian experimental contribution, is a colleague of Professor Wiseman in the Centre for Quantum Computation and Communication Technology.

"By using quantum states of light we made a more precise measurement than is possible through the conventional techniques using laser beams of the same intensity," Professor Huntington said.

"Curiously, we found that it is possible to have too much of a good thing. Squeezing beyond a certain point actually degrades the performance of the measurement, making it less precise than if we had used light with no squeezing."
