NASA Sets Record with Ion Thrusters Test

NASA has completed a 43,000 hour stress test — a record for ion thrusters — on a new rocket propulsion system that could extend future space travel to farther reaches of the solar system.

Developed by NASA’s Evolutionary Xenon Thruster Project, the 7-kilowatt ion thruster can burn 10-12 times longer than the conventional chemical thrusters used today. Though not practical for manned-spaceflight, the system could power exploratory rockets that reach outer planets and their moons.

Hot spots draw believers, but not doomsday

As the sun rose from time zone to time zone across the world on Friday, there was still no sign of the world’s end — but that didn’t stop those convinced that a 5,125-year Mayan calendar predicts the apocalypse from gathering at some of the world’s purported survival hot spots.

Many of the esoterically inclined expected a new age of consciousness — others wanted a party. But, in some places said to offer salvation from the end, fewer people showed up than officials had predicted — much to the disappointment of vendors hoping to sell souvenirs.

Here are some key places being marked by the fascination over doomsday rumors:

MEXICO

In an area of Mexico that was once the ancient Mayan heartland, spiritualists gathered in the darkness before dawn on Friday to prepare white clothes, drums, conch shells and incense. They believed the sunrise would herald the birth of a new and better age as a vast cycle in the Mayan calendar comes to an end.

Many people who came to Yucatan for the occasion were already calling it “a new sun” and “a new era.”

FRANCE

According to one rumor, a rocky mountain in the French Pyrenees will be the sole place on Earth to escape destruction. A giant UFO and aliens are said to be waiting under the mountain, ready to burst through and spirit those nearby to safety. But there is bad news for those seeking salvation: French gendarmes, some on horseback, blocked outsiders from reaching the Bugarach peak and its village of some 200 people.

Eric Freysselinard, head of local government, said the security forces had “partially stopped the new age enthusiasts as well as curious people from coming to the area.”

Meanwhile, some Bugarach residents dressed up like aliens, with tinfoil costumes and funnels and fake antenna on their heads, strolling around their village Friday to make light of the rumored UFO prophecy.

RUSSIA

Doomsday rumors have prompted some people across Russia to stock up on candles, water, canned foods and other non-perishable foods. The apocalypse has proven a good business, with some shops selling survival aid packages that include soap and vodka.

In Moscow, salvation has also been promised in the underground bunker for the former Soviet dictator Josef Stalin — with a 50 percent refund if nothing happens. An underground stay was originally priced at 50,000 rubles ($ 1,625) but dropped to 15,000 ($ 490) a week ahead of the feared end.

The bunker, located 65 meters (210 feet) below ground, was designed to withstand a nuclear attack. Now home to a small museum, it has an independent electricity supply, water and food — but no more room, because the museum has already sold out all 1,000 tickets.

BRITAIN

Hundreds of people have converged on Stonehenge for an “End of the World” party that coincides with the Winter Solstice.

Arthur Uther Pendragon, Britain’s best-known druid, said he was anticipating a much larger crowd than usual at Stonehenge this year. But he doesn’t agree that the world is ending, noting that he and fellow druids believe that things happen in cycles.

“We’re looking at it more as a new beginning than an end,” he said. “We’re looking at new hope.”

Meanwhile, end-of-days parties will be held across London on Friday. One event billed as a “last supper club” is offering a three-course meal served inside an “ark.”

SERBIA

Some Serbs are saying to forget that sacred mountain in the French Pyrenees. The place to be Friday is Mount Rtanj, a pyramid-shaped peak in Serbia already drawing cultists.

According to legend, the mountain once swallowed an evil sorcerer who will be released on doomsday in a ball of fire that will hit the mountain top. The inside of the mountain will then open up, becoming a safe place to hide as the sorcerer goes on to destroy the rest of the world. In the meantime, some old coal mine shafts have been opened up as safe rooms.

On Friday a New Age group called “The Spirit of Rtanj” was holding a conference there. Participants, however, said they expect not the end of time but the start of a new time cycle. Locals turned out to sell brandy and herbs.

“There will be no tragedy, no doomsday,” said resident Dalibor Jovic. “It was supposed to happen at 12:12 and I think that time has passed. So, we can now go on with our lives and be happy to be alive.”

TURKEY

A small Turkish village known for its wines, Sirince, has also been touted as the only place after Bugarach that would escape the world’s end. But on Friday journalists and security officials outnumbered cultists. This outcome disappointed local business people who had prepared a range of doomsday products to sell, including a specially labeled Doomsday wine and Turkish delight candy whose “best before” date was Dec. 21, 2012. One restaurant prepared a special “last meal” menu that included a “heaven kebab” and “forbidden fruit dessert.”

ITALY

Another spot said to be spared: Cisternino, a beautiful small town in southern Italy in an area of trulli, traditional dry stone huts with conical roofs. The notion that Cisternino could be a safe haven at world’s end derives from an Indian guru, Babaji, who said “Cisternino will become an island” at world’s end. His followers built a community in Cisternino centered on an ashram built in 1979. Hotel bookings are up this weekend.

Mayor Donato Baccaro told the AP that the beauty of the place has inspired many foreigners to live there. “This confirms that this place has a special energy,” he said.

CHINA

A fringe Christian group has been spreading rumors about the world’s impending end, prompting Chinese authorities to detain more than 500 people this week and seize leaflets, video discs, books and other material.

Those detained are reported to be members of the group Almighty God, also called Eastern Lightning, which preaches that Jesus has reappeared as a woman in central China. Authorities in the province of Qinghai say they are waging a “severe crackdown” on the group, accusing it of attacking the Communist Party and the government.

U.S.

Dozens of Michigan schools canceled classes for thousands of students to cool off rumored threats of violence and problems related to doomsday. The fears were exacerbated by the recent shooting at a Connecticut elementary school, which “changed all of us,” the school system in Genesee County said. “Canceling school is the right thing to do.”

Elwood V. Jensen, Pioneer in Breast Cancer Treatment, Dies at 92

Tony Jones/Cincinnati Enquirer, via Associated Press

Elwood V. Jensen in 2004.

Elwood V. Jensen, a medical researcher whose studies of steroid hormones led to new treatments for breast cancer that have been credited with saving or extending hundreds of thousands of lives, died on Dec. 16 in Cincinnati. He was 92.

The cause was complications of pneumonia, his son, Thomas Jensen, said.

In 2004 Dr. Jensen received the Albert Lasker Basic Medical Research Award, one of the most respected science prizes in the world.

When Dr. Jensen started his research at the University of Chicago in the 1950s, steroid hormones, which alter the functioning of cells, were thought to interact with cells through a series of chemical reactions involving enzymes.

However, Dr. Jensen used radioactive tracers to show that steroid hormones actually affect cells by binding to a specific receptor protein inside them. He first focused on the steroid hormone estrogen.

By 1968, Dr. Jensen had developed a test for the presence of estrogen receptors in breast cancer cells. He later concluded that such receptors were present in about a third of those cells.

Breast cancers that are estrogen positive, meaning they have receptors for the hormone, can be treated with medications like Tamoxifen or with other methods of inhibiting estrogen in a patient’s system, like removal of the ovaries. Women with receptor-rich breast cancers often go into remission when estrogen is blocked or removed.

By the mid-1980s, a test developed by Dr. Jensen and a colleague at the University of Chicago, Dr. Geoffrey Greene, could be used to determine the extent of estrogen receptors in breast and other cancers. That test became a standard part of care for breast cancer patients.

Scientists like Dr. Pierre Chambon and Dr. Ronald M. Evans, who shared the 2004 Lasker prize with Dr. Jensen, went on to show that many types of receptors exist. The receptors are crucial components of the cell’s control system and transmit signals in an array of vital functions, from the development of organs in the womb to the control of fat cells and the regulation of cholesterol.

Dr. Jensen’s work also led to the development of drugs that can enhance or inhibit the effects of hormones. Such drugs are used to treat prostate and other cancers.

Elwood Vernon Jensen was born in Fargo, N.D., on Jan. 13, 1920, to Eli and Vera Morris Jensen. He majored in chemistry at what was then Wittenberg College in Springfield, Ohio, and had begun graduate training in organic chemistry at the University of Chicago when World War II began.

Dr. Jensen wanted to join the Army Air Forces, but his poor vision kept him from becoming a pilot. During the war he synthesized poison gases at the University of Chicago, exposure to which twice put him in the hospital. His work on toxic chemicals, he said, inspired him to pursue biology and medicine.

Dr. Jensen studied steroid hormone chemistry at the Swiss Federal Institute of Technology on a Guggenheim Fellowship after the war. While there, he climbed the Matterhorn, one of the highest peaks in the Alps, even though he had no mountaineering experience. He often equated his successful research to the novel approach taken by Edward Whymper, the first mountaineer to reach the Matterhorn’s summit. Mr. Whymper went against conventional wisdom and scaled the mountain’s Swiss face, after twice failing to reach the summit on the Italian side.

Dr. Jensen joined the University of Chicago as an assistant professor of surgery in 1947, working closely with the Nobel laureate Charles Huggins. He became an original member of the research team at the Ben May Laboratory for Cancer Research (now the Ben May Department for Cancer Research) in 1951, and became the director after Dr. Huggins stepped down.

He came to work at the University of Cincinnati in 2002, and continued to do research there until last year.

His first wife, the former Mary Collette, died in 1982. In addition to his son, Dr. Jensen is survived by his second wife, the former Hiltrud Herborg; a daughter, Karen C. Jensen; a sister, Margaret Brennan; two grandchildren; and three great-grandchildren.

Dr. Jensen’s wife was found to have breast cancer in 2005. She had the tumor removed, he said in an interview, but tested positive for the estrogen receptor and was successfully treated with a medication that prevents estrogen synthesis.

Airlines' plans for 2013 up in the air

Airfares will be on the rise in 2013, and those niggling airline fees will metamorphose into optional bundles of services.

Meanwhile, onboard amenities, such as Internet access, entertainment options and refreshed interiors, will abound among U.S. carriers, but tight seating in coach probably won't improve.

And 2013 might be the year you'll finally be able to keep your smartphone, iPad or Kindle turned on during takeoffs and landings.

Those are some of the predictions airline industry experts foresee in the new year. Here's the lowdown on fares, fees and flight experience for 2013.

Higher fares forecast

Airlines pushed through six fare increases in 2012. Expect a similar number in the new year, said Rick Seaney, co-founder of FareCompare.com.

"I wouldn't be surprised to see airfares rise like they did this year, between 3 and 6 percent domestically," Seaney said. That's because airlines will succeed in properly balancing supply and demand by trimming the number of seats they offer to match "decent, but bordering on tepid, demand."

Fares are typically driven by four main factors: competition, most of all, then supply, demand and oil prices. "If you look at those drivers, they are, for the most part, on the airlines' side, which gives them pricing power," Seaney said.

That doesn't mean there won't be good airfare deals on some flights on some routes. And consumers will still see lower prices during off-peak days, such as Tuesday, Wednesday and Saturday departures and off-peak seasons, such as late January and early February. Like this year, summertime fares probably will stay relatively high, he said.

Airline mergers can also affect fares, and a huge one could take place early in 2013. American Airlines and US Airways are in talks about combining.

The general consensus among consumer advocates is that airline mergers aren't good for passengers.

"Any time you have two big airlines merging, that means consumers have less choice and competition is reduced, which only translates to higher prices," said Charlie Leocha, director of the Consumer Travel Alliance.

However, a bit of new evidence bucks that conventional wisdom. Despite four mega-mergers in the U.S. airline industry during the past seven years, fares have not increased significantly, just 1.8 percent per year, according to a December report from professional services firm PwC. In fact, average domestic fares decreased 1 percent from 2004 to 2011 when inflation is factored in, the report found.

Fliers know full well, however, that the fare isn't all that counts nowadays. There are those fees.

Fees get a makeover

The most noticeable trend in recent years with airline fees is that there are more of them: fees for checked bags, aisle seats, onboard meals, among many others. 

"What we hear is that people pay their fare and get to the airport and feel they're constantly being nickeled-and-dimed to death for things that used to be included," said Kate Hanni, founder of FlyersRights.org. 

The top five U.S. carriers alone generated more than $12 billion in fees in 2011, with even more expected through 2012, according to the PwC report.

What consumers call fees, airlines call "unbundling" — making a la carte choices from services that used to be included in the fare.

A likely trend for 2013 might be called "rebundling," airlines packaging a few now-optional services and charging for a tier of service.

Putin signs ban on U.S. adoptions of Russian children

MOSCOW (Reuters) - President Vladimir Putin signed a law on Friday that bans Americans from adopting Russian children and imposes other sanctions in retaliation for a new U.S. human rights law that he says is poisoning relations.

Washington has called the new Russian law misguided, saying it ties the fate of children to "unrelated political considerations", and analysts say it is likely to deepen a chill in U.S.-Russia relations and harm Putin's image abroad.

Fifty-two children whose adoptions by American parents were underway will now remain in Russia, the Interfax news agency cited Russia's child rights commissioner, Pavel Astakhov, as saying.

The new law, which has also ignited outrage among Russian liberals and child rights' advocates, takes effect on January 1.

The legislation, whose text was issued by the Kremlin, will also outlaw some non-governmental organizations that receive U.S. funding and impose a visa ban and asset freeze on Americans accused of violating the rights of Russians abroad.

Pro-Kremlin lawmakers initially drafted the bill to mirror the U.S. Magnitsky Act, which bars entry to Russians accused of involvement in the death in custody of anti-corruption lawyer Sergei Magnitsky and other alleged rights abuses.

The restrictions on adoptions and non-profit groups were added to the legislation later, going beyond a tit-for-tat move and escalating a dispute with Washington at a time when ties are already strained by issues such as the Syrian crisis.

The adoption ban may further tarnish Putin's international standing at a time when the former KGB officer is under scrutiny over what critics say is a crackdown on dissent since he returned to the Kremlin for a third term in May.

"The law will lead to a sharp drop in the reputation of the Kremlin and of Putin personally abroad, and signal a new phase in relations between the United States and Russia," said Lilia Shevtsova, an expert on Putin with the Carnegie Moscow Centre.

"It is only the first harbinger of a chill."

Putin's spokesman, Dmitry Peskov, said the Magnitsky Act - the U.S. bill which prompted the new Russian law - had "seriously undermined" the "reset", the moniker for the effort U.S. President Barack Obama launched early in his first term to improve relations between the former Cold War foes.

Putin has backed the hawkish response with a mixture of public appeals to patriotism, saying Russia should care for its own children, and with belligerent denunciations of what he says is the U.S. desire to impose its will on the world.

SHARP CRITICISM

Seeking to dampen criticism of the move, Putin also signed a decree ordering an improvement in care for orphans.

Critics of the Russian legislation say Putin has held the welfare of children trapped in a crowded and troubled orphanage system hostage to political maneuvering.

"He signed it after all! He signed one of the most shameful laws in Russian history," a blogger named Yuri Pronko wrote on the popular Russian site LiveJournal.

A hashtag that translates as "Putin eats children" was being widely used on Twitter in Russia on Friday, and pro-Kremlin microbloggers hit back with: "Putin supported orphans".

Russian authorities say the deaths of 19 Russian-born children adopted by American parents in the past decade were one of the main motives for the law as well as what they perceive as the overly lenient treatment of those parents by U.S. courts and law enforcement agencies.

However, critics of the bill say Russian orphanages are woefully overcrowded and that adoptions by Russian families remain modest, with some 7,400 adoptions in 2011 compared with 3,400 adoptions of Russian children by families abroad.

Apple still said to account for 87% of North American tablet traffic as Kindle Fire, Nexus 7 gain

Apple’s (AAPL) share of the global tablet market is in decline now that low-cost Android slates are proliferating, but the iPad still appears to be the most used tablet by a huge margin. Ad firm Chitika regularly monitors tablet traffic in the United States and Canada and in its latest report, Apple’s iPad was responsible for almost 90% of all tablet traffic across the company’s massive network.

[More from BGR: Samsung looks to address its biggest weakness in 2013]

Using a sample of tens of millions of impressions served to tablets between December 8th and December 14th this year, Chitika determined that various iPad models collectively accounted for 87% of tablet traffic in North America. That figure is down a point from the prior month but still represents a commanding lead in the space.

[More from BGR: New purported BlackBerry Z10 specs emerge: 1.5GHz processor, 2GB RAM, 8MP camera]

The next closest device line, Amazon’s (AMZN) Kindle Fire tablet family, had a 4.25% share of tablet traffic during that period, up from 3.57% in November. Samsung’s (005930) Galaxy tablets made up 2.65% of traffic, up from 2.36%, and Google’s (GOOG) Nexus 7 and Nexus 10 tablets combined to account for 1.06% of tablet traffic in early December.

“Despite these gains by some of the bigger players in the tablet marketplace, there has been a negligible impact to Apple’s dominant usage share,” Chitika wrote in a post on its blog.

Piano maker Steinway takes down “for sale” sign

NEW YORK (Reuters) – Steinway Musical Instruments Inc, the famous manufacturer of pianos, saxophones and trumpets, said on Wednesday it had decided not to sell itself following a 17-month-long exploration of strategic alternatives.

An American icon synonymous with handmade grand pianos, Steinway has struggled to keep its production margins competitive amid stagnant sales, and has seen its shares plunge 10 percent year-to-date. Still, its third-quarter earnings last month offered signs that cost-cutting was paying off.

In a statement on Wednesday, Steinway said it had received several non-binding indications of interest in buying the company, following talks with other companies in the sector as well as private equity, yet these did not offer more value than its own strategic plan.

“We will continue to focus management’s efforts on execution of that plan and we look forward to a prosperous 2013,” Steinway CEO Michael Sweeney said in the statement.

An in-principle agreement to sell its band instrument division to an investor group led by two of its board members, Dana Messina and John Stoner, was also scrapped in light of the current operating performance of the band division, Steinway said.

In July 2011, Messina, Stoner and other members of management made an offer for Steinway’s band instrument and online music divisions, prompting the company to set up a special committee in order to assess it.

Later that month, Steinway asked investment bank Allen & Company LLC to a assist the special committee on exploring strategic alternatives that could also include selling the whole company outright to other interested parties.

By October 2011, Messina had stepped down as CEO of the company after 15 years at the helm to pursue his bid, yet he remained a board member. He was replaced by Sweeney, a chairman of the board of Star Tribune Media Holdings and a former president of Starbucks Coffee Company (UK) Ltd.

Steinway said on Wednesday that it was continuing a separate process to sell its leasehold interest in New York’s Steinway Hall building, situated on Manhattan’s 57th Street, and was in talks with several parties.

According to its website, Steinway & Sons, the company’s piano unit, opened the first Steinway Hall on 14th Street in Manhattan in 1866.

With a main auditorium of 2,000 seats, it became New York City’s artistic and cultural center, housing the New York Philharmonic until Carnegie Hall opened in 1891. These days, Steinway Hall is a showroom for the company’s instruments.

The Waltham, Massachusetts-based company’s pianos have been used by legendary artists such as Cole Porter and Sergei Rachmaninoff and by contemporary ones like Chinese concert pianist Lang Lang.

McCormick Place development fight held over to 2013

The lengthy battle for control over property slated for hotel development adjacent to McCormick Place will extend into 2013 after a federal bankruptcy judge on Thursday gave the long-time property owners more time to show their plans have financial viability.

Judge Jack Schmetterer this month had given Olde Prairie Block Owner LLC until Thursday to show him it had plausible plans to repay its lenders, chief among them CenterPoint Properties Trust.

Olde Prairie, whose principals include Pamela Gleichman, her husband, Karl Norberg, and Gunnar Falk, have proposed selling portions of the properties for hotel development, with two deals projected to bring in $180 million. The developers said this would be sufficient to pay back lenders in full and develop the properties.

The lender, CenterPoint Properties Trust, contends the plan is not financially viable, in part because the sales agreements contained contingencies. As well, it argued that the structure of the deals would not provide sufficient funds to fully repay lenders.

Schmetterer gave Olde Prairie until Jan. 10 to show the potential buyer of the larger parcel had a firm financing commitment. He also is seeking greater clarity in the sales contract language.

The case has been closely watched because it involves parcels long eyed for development linked to McCormick Place. Speculation has swirled around possibilities,from hotels, restaurants and entertainment venues, including a possible casino, to an arena that could host the DePaul men's basketball team as well as corporate and religious assemblies.

The properties include a 3.67-acre parcel at 330 E. Cermak Rd., directly north of the administrative offices of the Metropolitan Pier and Exposition Authority, the state-city agency that owns McCormick Place, and a 1.23-acre parcel directly west of it at 230 E. Cermak, across the street from the center's West Building.

The authority, known as McPier, this month purchased a separate parcel on the 230 E. Cermak block, with an eye toward gathering enough property to expand hotel, restaurant and entertainment amenities near the convention campus.

Sen. Reid warns U.S. poised to go over 'fiscal cliff'

Rana Foroohar, Time magazine's assistant managing editor for business news, talks to Rebecca Jarvis and Jeff Glor about what a drop off the "fiscal cliff" could mean to businesses and consumers.

WASHINGTON (Reuters) - The top Democrat in the Senate warned on Thursday that the United States looks to be headed over the "fiscal cliff" of tax hikes and spending cuts that will start next week if squabbling politicians do not reach a deal.

Majority Leader Harry Reid told the Senate in a speech that "it looks like that is where we're headed."

He called on the Republicans who control the House of Representatives to prevent the worst of the fiscal shock by getting behind a Senate bill to extend existing tax cuts for all except those households earning more than $250,000 a year.

With the House not in session and the clock ticking toward the scheduled January start of tax increases and deep, automatic government spending cuts, Reid offered little hope.

"I don't know time-wise how it can happen now," he said.

President Barack Obama arrived at Andrews Air Force Base outside Washington after a flight from Hawaii on Thursday on his way back to the White House to try to restart stalled negotiations with Congress.

Obama made phone calls to congressional leaders on Wednesday from his vacation in Hawaii to try to revive the stalled talks to prevent the "fiscal cliff" scenario, which would worry world financial markets and could push the United States back into recession.

U.S. stocks fell to session lows after Reid's pessimistic remarks.

In addition, consumer confidence fell to a four-month low in December as the budget crisis sapped what had been a growing sense of optimism about the economy, a report released on Thursday showed.

"People are hearing about (the cliff) and it negatively impacts confidence and investor sentiment and even holiday sales," said Todd Schoenberger, managing partner at Landcolt Capital in New York.

The chances of a last-minute deal - at least one that would prevent tax hikes - remained uncertain, with Republicans and Democrats each insisting the other side move first amid continuing partisan gridlock.

The Senate, controlled by Democrats, was scheduled to meet later on Thursday but on matters unrelated to the "fiscal cliff."

Speaker John Boehner and other House Republican leaders, who say they are willing to take up a "fiscal cliff" measure only after the Senate acts on one, were to hold a conference call with Republican House members on Thursday.

The expectation for the call was that lawmakers would be told to get back to Washington within 48 hours to consider anything the Senate might pass.

Weather permitting, that would bring them to Washington with perhaps three days left before the deadline for action. Storms affecting the Midwest, the South and the Northeast played havoc with airline schedules.

'NOT WILLING'

"This isn't a one party or one house problem. This is (that) leaders in both parties in all branches of the government are not willing to make the deal that they know they have to make. Everybody wants their stuff but doesn't want to give up what they don't want to give up," Republican U.S. Representative Steven LaTourette told CNN.

The House and Senate passed bills months ago reflecting their own sharply divergent positions on the expiring low tax rates, which went into effect during the administration of Republican former President George W. Bush.

Democrats want to allow the tax cuts to expire on the wealthiest Americans. Republicans want to extend the tax cuts for everyone.

Congress has proven that it can act swiftly once an agreement is reached. Hope persisted that Republicans and Democrats might come up with a resolution before New Year's Day that could at least postpone the impact of the tax hikes and spending cuts while further discussions take place.

That gives some hope to world markets.

"There is still hope for a last-minute deal, otherwise we're in for a correction in January. People have already priced in an agreement. Without it, the market can't stay at these levels," a Paris-based trader said.

Another battle is just over the horizon in late January or early February over raising the debt ceiling, which puts a limit on the amount of money the U.S. government can borrow to pay its debts and can be raised only with the approval of Congress.

Republican leaders have said they will insist on more budget cuts as a condition of raising the ceiling. Without any action, the U.S. Treasury said on Wednesday the government is set to reach its $16.4 trillion debt ceiling on December 31.

The Treasury Department is to begin "extraordinary measures" to buy time. Many analysts believe the government can stave the default date off into late February.
