Lewis of US shoots 69, shares lead in Singapore

(AP) ? Stacy Lewis shared the lead with Na Yeon Choi at the HSBC Women's Champions after the South Korean birdied the 18th hole in a rain-delayed third round on Saturday.

Choi shot a 5-under 67 to tie the 28-year-old American at 14-under 202. Lewis, the overnight leader and reigning LPGA Player of the Year, had a 69.

Paula Creamer, who injured her shoulder in a car accident after a tournament in Thailand last weekend, shot 69 to trail the leaders by two shots.

Four golfers were three strokes behind Creamer ? American Danielle Kang (70), Spaniard Azahara Munoz (72), South Korean Sun Young Yoo (72) and Thai 17-year-old Ariya Jutanugarn (72).

Lewis and Choi were in the last group on the course and had just teed off on the 18th when a thunderstorm rolled in and caused a 2?-hour delay. Lewis was up a stroke when they left the course, but when they returned, Choi made a 10-foot birdie putt to pull even heading into Sunday.

The two golfers traded the lead throughout the day. Lewis bogeyed holes No. 1 and 3 to fall two strokes behind Choi. Lewis pulled even after reeling off three straight birdies ? including a 25-foot putt on No. 8 that barely caught the edge of the hole.

Choi moved atop the leaderboard again with a birdie on the 14th, but she bogeyed the next hole after missing a long par putt to give the lead right back.

Lewis maintained the one-shot advantage going into the 18th. And then the rain came.

"It was very frustrating," Lewis said. "It is what it is and luckily we got finished today. It's going to be tight tomorrow and we are going to have to make some putts."

Creamer, who was in the next-to-last group, said she barely made it off before the start of thunder and lightning.

"Sometimes it has its perks being second to last," she said. "Dinner will taste a lot better, especially not having to grind it out on the last hole."

Creamer, the 2010 U.S. Open champion, had low expectations coming into the tournament after injuring her shoulder in a five-car accident on the way to the Bangkok airport on Sunday night.

She said the pain was so bad Thursday morning that she wasn't sure if she'd play.

"I'm just so pleased to be out here, and let alone to be in contention on Sunday," Creamer said. "That's just beyond my imagination of what I thought even teeing it up on Thursday."

Top-ranked Yani Tseng had a 71 on Saturday. The five-time major winner hasn't won a tournament in nearly a year and could be in danger of losing her No. 1 spot to Choi, currently in second.

Choi can't overtake Tseng with a victory this week, but she is moving closer.

"I think that if I think about that tomorrow, then I don't think I can have good results," she said. "So I will try to just think about one shot at a time."

Mars trip to use astronaut poo as radiation shield

The man and woman aboard the Inspiration Mars mission set to fly-by the Red Planet in 2018Movie Camera will face cramped conditions, muscle atrophy and potential boredom. But their greatest health risk comes from exposure to the radiation from cosmic rays. The solution? Line the spacecraft's walls with water, food and their own faeces.

"It's a little queasy sounding, but there's no place for that material to go, and it makes great radiation shielding," says Taber MacCallum, a member of the team funded by multimillionaire Dennis Tito, who announced the audacious plan earlier this week.

McCallum told New Scientist that solid and liquid human waste products would get put into bags and used as a radiation shield ? as well as being dehydrated so that any water can be recycled for drinking. "Dehydrate them as much as possible, because we need to get the water back," he said. "Those solid waste products get put into a bag, put right back against the wall."

Food too, could be used as a shield, he said. "Food is going to be stored all around the walls of the spacecraft, because food is good radiation shielding," he said. This wouldn't be dangerous as the food would merely be blocking the radiation, it wouldn't become a radioactive source.

Water 1 ? Metals 0

The details of Inspiration Mars's plans have yet to be clarified, but the team has said it will be using "state-of-the-art technologies derived from NASA and the International Space Station".

One idea that is already under consideration by the agency's Innovative Advanced Concepts programme, which funds research into futuristic space technology, is a project called Water Walls, which combines life-support and waste-processing systems with radiation shielding.

Water has long been suggested as a shielding material for interplanetary space missions. "Water is better than metals for protection," says Marco Durante of the Technical University of Darmstadt in Germany. That's because nuclei are the things that block cosmic rays, and water molecules, made of three small atoms, contain more nuclei per volume than a metal.

Water shielding also has another benefit ? you can drink it. Such dual use is essential aboard a spacecraft, where space is at a premium. Applying this rationale, the Water Walls concept involves polyethylene bags that use osmosis to process clean drinking water from urine and faeces.

Sights and smells

Lining the walls of a spacecraft with layers of these bags creates a 40-centimetre-thick liquid shield. All of the bags would initially be filled with drinking water. The crew would then fill other bags with waste during the trip to Mars and swap them out for the now-empty water bags.

The osmosis-based processing is much simpler than the automated life-support systems aboard the International Space Station, making it less likely to fail during the long ride to Mars.

However, there are problems to be ironed out. The urine-to-water processing bags were tested in orbit on the last ever flight of the space shuttle in 2011 and found to be 50 per cent less efficient in microgravity than in ground-based tests.

Besides testing that the various bags work properly, the Water Walls team points out the more basic worry of dealing with the residual sights and smells. MacCallum made a similar point about the system to be used on Inspiration Mars: "Hopefully they're not clear bags," he said.

Solar danger

Not all bags need be equally unpleasant, though. The Water Walls concept also includes bags that scrub carbon dioxide from air, regulate temperature and grow algae for food ? although NASA hasn't yet taken those to space.

Inspiration Mars also plans to have an external water tank and the aluminium skin of the spacecraft itself for extra protection. This kind of shielding should keep astronauts safe from lower energy cosmic rays, says Ruth Bamford of the Rutherford Appleton Laboratory in Didcot, UK, who is working on creating magnetic "deflector shields" for spacecraft.

Organic material or aluminium is no defence against the burst of particles that occasionally spew out from the sun during a solar storm, however. "For this, putting three metres of concrete may not be enough to protect the astronauts," says Bamford. Inspiration Mars say they should be able to keep the upper rocket stage of their launch vehicle attached to the spacecraft for the whole of the trip, and point that towards the sun in the event of a flare.

Volcanic eruptions mask warming ? that's cool

U.S. Geological Survey

A new study indicates emissions from moderate volcanoes around the world, such as the Augustine Volcano in Alaska, shown here, can hide some of the effects of global warming.

By Megan Gannon
LiveScience

Volcanic eruptions, even small and moderate ones, might counter some of the effects of global warming, new research suggests.

The planet didn't heat up as much as scientists expected it to from 2000 to 2010 (though it?was still the warmest decade on record), and a new study finds that chemical compounds spewed during modest eruptions around the globe could be behind the trend.

When sulfur dioxide emitted by a volcano rises up to the stratospheric aerosol layer of the atmosphere, it undergoes chemical reactions, forming particles that reflect sunlight back into space instead of letting it get to the surface of the planet. This has a cooling effect on Earth that can help mitigate the impacts of heat-trapping greenhouse gasses.

Scientists observed an increase in these sun-scattering aerosols in the atmosphere from 2000 to 2010. Some studies suggested that emissions from rapidly developing countries in Asia could be largely to blame ? India and China, for example, are thought to have ramped up their sulfur dioxide output by about 60 percent over the decade through coal burning. But other studies pointed to volcanoes, which are also an important source of sulfur dioxide.

The authors of the new study used computer simulations to see which changes in the stratospheric aerosol layer could be attributed to coal burning in Asia and worldwide volcanic emissions from 2000 to 2010. The results suggested that moderate volcanic eruptions were behind the increases of aerosols in the atmosphere.

"This new study indicates it is emissions from small to moderate volcanoes that have been slowing the warming of the planet," Ryan Neely, who led the research as part of his doctoral thesis at the University of Colorado, Boulder, said in a statement.

The findings imply scientists should pay more attention to these types of eruptions when studying changes in Earth's climate, said study researcher Brian Toon, a professor at CU-Boulder, though he cautioned that in the long run, volcanoes won't be able to counterbalance global warming.

"Overall these eruptions are not going to counter the greenhouse effect," Toon said in a statement. "Emissions of volcanic gases go up and down, helping to cool or heat the planet, while greenhouse gas emissions from human activity just continue to go up."

Toon added that larger volcanoes can have a much bigger effect. For example, Mount Pinatubo, a volcano in the Philippines that erupted in 1991, ejected so much sulfur dioxide into the stratosphere that the planet cooled by 1 degree Fahrenheit (0.55 degrees Celsius) and stayed slightly cooler for more than two years.

The new research was detailed online in the journal Geophysical Research Letters.

Pope Benedict XVI and the road not taken (+video)

At one point, the young?Joseph Ratzinger looked like a budding church reformer. By the time he abdicated as pope this week, he had become one of the stoutest defenders of Catholic tradition.

By Robert Marquand,?Staff writer / February 13, 2013

By the time Pope Benedict XVI made his surprise announcement to abdicate, his image had become fixed as one of the stoutest defenders of tradition and an arch-enemy of change, liberality, and the reforming intent of the Vatican II council. But at the start of his career, he looked as if he might be a budding reformer himself. ?

The pope, then Joseph Ratzinger, collaborated on changes during Vatican II with Karl Rahner, a Jesuit star from Munich who in the 1970s was talked about as pope material in liberal circles. Mr. Rahner advocated women?s ordination, supported seekers in churches outside the Catholic faith, and his theology arced more toward a universal spirituality than institutional rules, emphasizing ?a?human search for meaning ? rooted in the unlimited horizon of God?s own being experienced within the world.?

The young Ratzinger in the 1960s was brought to Tubingen University partly by Catholic theologian Hans Kung (later censored for views bordering on heresy) and taught in a progressive Protestant-Catholic faculty.?

Ratzinger's first faculty lecture at Tubingen, eagerly awaited and still remembered today, stressed the importance of the interpretation of the Bible via church fathers of the pre-medieval era, at a time of relative excitement in scholarly circles over new "subjective" and "spiritual" interpretations of scripture. Mr. Kung was disappointed, his colleagues remember.?

Later in the mid-1960s Ratzinger experienced student campus protests firsthand. For a shy scholar whose vision of church was hewn in the clean and well-ordered Alpine villages of Bavaria ? the experience deeply soured him on change as well as the often excessive experiments of Vatican II to open the church up "to the modern world," as the saying went.?

Vatican II was heady days at a time of ferment, but neither Ratzinger nor the church he eventually led, ever made the leap. Faced with a changing world, Benedict opted for a church of greater purity and reliance on past traditions ??even as his tenure will be marked by a priestly child abuse scandal that two years ago was described as the biggest challenge faced by Rome since the Reformation.

Yesterday Vatican officials affirmed the outgoing Benedict will not personally direct the choice of his successor. But the outgoing pontiff has been so instrumental in shaping the policies and personnel of the Roman Catholic church that his presence won?t matter, analysts say.

For 24 years Benedict, as Cardinal Ratzinger, ruled the roost in the Vatican as Pope John Paul II?s enforcer, the powerful head of the Congregation for the Doctrine of the Faith, and he has overseen a tightening, not a loosening, of church doctrine.

Since 2005 he further consolidated power as pope. So the conclave of cardinals and bishops meeting in Rome next month are there precisely due to their loyalty to Benedict?s vision of the Roman church.

The effect of Benedict?s reign as pope in this sense cannot be understated.

To take one example: In recent years under direct Vatican influence one of the largest Benedictine training schools in the US has, against the sentiment of its teaching clergy, been forced to disallow males and females to study in classes together. So the "Benedict effect" is not something found only in books and encyclicals; it has had an effect?"on the ground," as one Benedictine theologian reports, off the record.?

In a church still quite divided on moral issues, sexuality, modernity, the concept of priest, and so on, it is unclear whether the pope?s resignation, itself an unusual break from the past, may lead to other changes.

Benedict oversaw a 2,000-year-old church with an all-male hierarchy that struggled to respond to a child abuse and pedophilia scandal that reached new excesses two years ago on both sides of the Atlantic during the "year of the priest."

The German pope did not create what some hoped would be a ?Benedict generation? with his robust defense of church doctrines and a controversial return to a more traditional liturgy. While?some conservative religious orders have seen some new applicants in the US, the overall numbers remain a far-cry from those before 1960. Instead, church issues among youth seem pressing, at least in the post-modern West that Benedict had hoped to appeal to with a new Catholic moment. If that moment never comes, says?one New York-based Jesuit, ?The church is going to go one way and the rest of us are going to go another.?

The child abuse scandal, which many dissidents in the church say is a result of the policies of all-male clergy and celibacy (the Vatican denies this) did allow, however briefly, space for different voices to be heard, and for issues treated by church fathers as settled for all time, to be raised.

The issues run from sex and gender to spiritual authority inside the church. They track the shrinking of Mass attendance in the West, the sharp downturn of youth desiring to be priests, and the angry reaction of females (again in the US and Britain) who see roles as clergy closed off when in many churches they are the most faithful.

In the midst of the priestly child abuse scandal, the church issued a circular that put women?s ordination into the same category of disciplinary crimes as heresy, pedophilia, and promoting schism.?Benedict was given credit for suggesting that wearing a condom is acceptable in certain odd cases, such as that of a male prostitute. But with many Catholics no longer even following church teaching on condoms, and with the pope visiting Africa and talking about abstinence and no wearing of condoms, many can?t relate.

The pedophile cases also sparked what many Catholics say is a need for a greater spiritual awakening in a church that has placed a great emphasis on institutional authority; they placed a critical focus on old assumptions that male priests, through the act of their ordination, are holier or more spiritually endowed than ordinary members of the laity.

The British newspaper The Guardian pointed out in an editorial that it could not find a single current liberal candidate for pope, and quoted from Carlo Maria Martini, a cardinal, who said before passing last year that, ?The church is tired in Europe and America. Our culture has aged, our churches are large, our religious houses are empty, and the bureaucracy of the church climbs higher, our rituals and our clothes are pompous?[the church] must recognize her mistakes and must follow a path of radical change, starting with the pope and the bishops.?

Yet many following the daily operations of the Holy See feel there is unlikely to be any revolutionary ?Papal Spring.? Some reform-minded Catholics and many who have left the church say the Vatican is so deeply into the wrong questions, and has been relying so heavily on those who are not interested in questioning in the first place, that any positive reforms will only be on the margins.?

(AP) ? George Lopez is taking over as master of ceremonies of the annual Playboy Jazz Festival.

The comedian was announced as the festival's new host Thursday at an event at the Playboy Mansion.

"This is iconic," said the former star of the ABC sitcom "George Lopez" and the TBS talk show "Lopez Tonight." ''I've never been here before. I was married for 17 years. I couldn't even have a Playboy air freshener."

Bill Cosby previously served as the festival's host for more than 30 years. Cosby was a fixture at the gathering of jazz luminaries since the first festival was held in 1979.

Lopez said Cosby called him to give him advice on the gig. His tips included not letting musicians in his dressing room "because they'll eat all your food and drink all your drink," joked Lopez.

This year's show will feature such artists as Herbie Hancock, Jeffrey Osborne, Sheila E. and Grace Kelly, who were on hand at Thursday's event.

The Playboy Jazz Festival is scheduled for June 15 and 16 at the Hollywood Bowl.
