Vatican Raises Possibility of Early March Conclave

The Vatican raised the possibility Saturday that the conclave to elect the next pope might start sooner than March 15, the earliest date possible under current rules that require a 15-20 day waiting period after the papacy becomes vacant.

Vatican spokesman The Rev. Federico Lombardi said that the Vatican rules on papal succession are open to interpretation and that "this is a question that people are discussing."

"It is possible that church authorities can prepare a proposal to be taken up by the cardinals on the first day after the papal vacancy" to move up the start of conclave, Lombardi said.

He explained that the 15-20 day rule is in place to allow time for the arrival of "all those (cardinals) who are absent" to take part in the conclave in the usual circumstances of convening after a pope dies. But in this case, the cardinals already know that this pontificate will end on Feb. 28 with the resignation of Pope Benedict XVI, and therefore can get to Rome in plenty of time to take part in the conclave, Lombardi said.

The date of the conclave's start is important because Holy Week begins March 24, with Palm Sunday Mass followed by Easter Sunday on March 31. In order to have a new pope in place in time for the most solemn liturgical period on the church calendar, he would need to be installed as pope by Sunday, March 17. Given the tight time-frame, speculation has mounted that some sort of arrangement would be made to start the conclave earlier than a strict reading of the law would allow.

Questions about the start of the conclave have swirled ever since Benedict announced on Feb. 11 that he would retire, the first pontiff in 600 years to abdicate rather than stay in office until death. As a result, his decision has created a host of questions about how the Vatican will proceed, given that its procedures for the so-called "sede vacante" — or vacant seat — period between papacies won't begin with a pope's death.

Lombardi also gave more details about Benedict's final audiences and plans for retirement, saying already 35,000 people have requested tickets for his final general audience to be held in St. Peter's Square on Feb. 27. He said Benedict would spend about two months in the papal summer retreat at Castel Gandolfo south of Rome immediately after his abdication, to allow enough time for renovations to be completed on his retirement home — a converted monastery inside the Vatican walls.

That means Benedict would be expected to return to the Vatican, no longer as pope, around the end of April or beginning of May, Lombardi said.

He was asked if and when the pope would meet with his successor and whether he would participate in his installation Mass; like many open questions about the end of Benedict's papacy, both issues simply haven't yet been resolved, Lombardi said.

US Q4 industrial output stronger than thought: Fed

WASHINGTON: US industrial production fell in January but the final quarter of last year was much stronger than originally thought, the Federal Reserve reported on Friday.

January's production contracted 0.1 per cent, and manufacturing output fell 0.4 per cent.

But industrial production as a whole expanded at a 2.6 per cent annual pace in the October-December 2012 quarter, compared to the previous estimate of just 1.0 per cent, and manufacturing expanded 1.9 per cent, compared to the previous estimate of 0.2 per cent.

That suggested that the initial government estimate of an 0.1 per cent contraction in the economy last quarter could be revised upward.

Manufacturing output in December was revised up to 1.1 per cent and November 1.7 per cent.

January's production was hit mainly by a 3.9 per cent contraction in automotive products, while energy production surged 3.1 per cent.

Why We Walk … and Run … And Walk Again to Get Where We're Going

You have to get to a bus stop to catch the once-an-hour express ... or to a restaurant to meet a friend ... or to a doctor's office. You've got maybe a half a mile to cover and you're worried you'll be late. You run, then you stop and walk, then run some more.

But wait. Wouldn't it be better to run the whole way?

Not necessarily.

A new study by an assistant professor of mechanical engineering at Ohio State University tests the theory that people subconsciously mix walking and running so they get where they need to. The idea is that "people move in a manner that minimizes energy consumption," said the professor, Manoj Srinivasan.

Srinivasan asked 36 subjects to cover 400 feet (122 meters), a bit more than the length of a football field. He gave them a time to arrive at the finish line and a stopwatch. If the deadline was supertight, they ran. If they had two minutes, they walked. And if the deadline was neither too short nor too far off, they toggled between walking and running.

The takeaway: Humans successfully make the walk-run adjustment as they go along, based on their sense of how far they have to go. "It's not like they decide beforehand," Srinivasan said. (Get tips, gear recommendations, and more in our Running Guide.)

The Best Technique for "the Twilight Zone"

"The mixture of walking and running is good when you have an intermediate amount of time," he explained. "I like to call it 'the Twilight Zone,' where you have neither infinite time nor do you have to be there now."

That ability to shift modes served ancient humans well. "It's basically an evolutionary argument," Srinivasan said. A prehistoric human seeking food would want to move in a way that conserves some energy so that if food is hard to find, the hunter won't run out of gas—and will still be able to rev it up to escape predators.

The study, published on January 30 in the Journal of the Royal Society Interface, doesn't answer that question of how we make such adjustments.

Runners: Take a Break if You Need It

The mix of walking and running is also something that nonelite marathoners are familiar with. Covering 26.2 miles might take less of a toll if the runner stops running from time to time, walks a bit, then resumes a jogging pace. "You use less energy overall and also give yourself a bit of a break," Srinivasan noted. (Watch: An elite marathoner on her passion for running.)

One take-home lesson is: Runners, don't push it all the time. A walk-run mix will minimize the energy you expend.

Lesson two: If you're a parent walking with your kid, and the kid lags behind, then runs to catch up, then lags again, the child isn't necessarily trying to annoy you. Rather, the child is perhaps exhibiting an innate ability to do the walk-run transition.

Potential lesson three: The knowledge that humans naturally move in a manner that minimizes energy consumption might be helpful in designing artificial limbs that feel more natural and will help the user reduce energy consumption.

The big question for Manoj Srinivasan: Now that he has his walk-run theory, does he consciously switch between running and walking when he's trying to get somewhere? "I must admit, no," he said. "When I want to get somewhere, I just let the body do its thing." But if he's in a rush, he'll make a mad dash.

"Talk to you tomorrow," he signed off in an email to National Geographic News. "Running to get to teaching now!"

Falling Meteor Causes Blast, Injures Hundreds

A massive meteor shower slammed into Earth near the Russian city of Chelyabinsk, located about 1,000 miles east of Moscow in the Ural Mountains.

Dashboard cameras captured a blinding flash of light streaking across the sky. Moments later, the fragments smashed into the ground. The impact, and the sonic boom of the meteor entering the atmosphere, shattered windows around the city and knocked over a wall at a zinc factory.

Witnesses said they thought a war had broken out.

"I saw a body moving in the skies. In a moment there came a flash - we first thought it was fireworks but a moment later we saw a trace as if from the rocket followed by an explosion in a couple of minutes. The window broke ... tea, bread, water - everything fell on the floor," one restaurant waiter in Chelyabinsk said.

Officials told the Russian news agency Interfax that more than 500 people were injured, most by broken glass. Of the 12 people hospitalized, at least three of them were in serious condition.

One scientist told Russian television the meteor was a big one, weighing perhaps tens of tons, but stressed that it was not related to the asteroid that is expected to buzz close to Earth later today.

Regional officials said the one large fragment fell in a lake, but debris had been reported in three parts of Russia and in Kazakhstan.

Schools in the region closed for the day after most of the windows were blown out, citing freezing temperatures, which were below zero degrees Fahrenheit during the day.

Debris from the meteor was found in three sites around the country, but emergency services say ground zero was Chebarkul Lake, just west of Chelyabinsk.

The meteor knocked out cell phone networks, but electricity and water supplies were not affected. Rosatom said all its nuclear power facilities were functioning normally.

Mumbai attack movie hits cinemas on Mar 1

MUMBAI: Memories of the Mumbai terror attacks of November 2008 still evoke fear among residents of the city.

And those old wounds are expected to reopen now that a Bollywood movie about the incident is set to hit the big screens.

India's financial capital came to a virtual standstill on 26 November 2008.

The attacks which lasted for four days drew widespread global condemnation.

The Pakistan-based terrorists, who were members of Lashkar-e-Taiba, killed 164 people and wounded at least 308 in their wake.

But the undying spirit of the citizens of Mumbai helped the city crawl back to its feet soon after the carnage ended.

And now, Bollywood is all set to release a film which will depict the gruesome terror attacks that shook Mumbai nearly five years ago.

The movie "The Attacks of 26/11" will hit cinemas on 1 March.

A publicity event to launch the movie's music was held at the Gateway of India.

Around 200 students lit candles in memory of the 26/11 victims.

The event then continued at Café Leopold where two of the ten terrorists launched their initial strikes in the first wave of attacks on the city.

Film maker Ram Gopal Varma said: "I strongly believe as a film maker and as a human being that the attacks of 26/11 which happened in 2008 are not against any community in particular. I think it is an attack on human beings and committed by certain inhuman elements."

The mood was sombre as the film maker and lead actor showed off a few teasers from the movie.

The usually reclusive veteran Bollywood actor Nana Patekar, who plays the lead role in the film, shed his inhibitions and spoke to the media with unusual frankness.

He said: "I feel pained whenever I think about the attacks of 26/11. The film depicts the mindset of the terrorists who went on a carnage in Mumbai. We are trying to portray through our films what steps can be taken to prevent such types of attacks in future."

The owner of the Leopold was also present at the event, and has played himself in the film.

The music launch of the film has reignited the anger and bitterness in the minds of Indian citizens.

But as in 2008, the movie also shows the world that Mumbai and its people have picked up the pieces and are refusing to let fear of terror attacks get in the way of their daily lives.

What is the 'Soap Opera Effect'?

Do movies look weird on your new TV? Does everything have a hyper-real, ultra-smooth motion to it? Are you sure something is happening with the TV's image you don't like, but you can't figure out what?

Chances are, what you're seeing is called the "Soap Opera Effect," as descriptive a moniker as we get in tech, in that this feature makes everything on your TV look like a cheap soap opera.

Here's what it is, what it does, and how to turn it off.

The Soap Opera Effect, or SOE, is actually a feature of many modern televisions. It's called "motion smoothing," "motion interpolation," or "ME/MC" for motion estimation/motion compensation. Some people don't notice it, some don't mind it, and a few even like it. From e-mails and article comments I've read, it seems most people hate it.

This motion "whatever" was ostensibly developed to help decrease apparent motion blur on LCDs. All LCD TVs have difficulty with motion resolution. Which is to say, any object onscreen that's in motion will be less detailed (slightly blurry) compared with that same object when stationary. High-refresh-rate LCDs (120Hz and 240Hz) were developed to combat this problem. Check out "What is refresh rate" for a more in-depth description of this. The short version: in order for high-refresh-rate TVs to be most effective, they need new, real frames to insert in-between the original frames.

Thanks to speedy processors, TVs can "guess" what's happening between the frames captured by the camera originally. These new frames are a hybrid of the frame before and the frame after. By creating these frames, motion blur is reduced. With 30fps and 60fps content, this is great. Content like sports have better detail with motion, and there are minimal side effects (beyond errors/artifacts possible with cheaper/lesser motion interpolation processing).

Film
However, with 24fps content (namely Hollywood movies and most nonreality, prime-time TV shows like sitcoms and dramas), there's a problem. The cadence of film, and the associated blurring of the slower frame rate's image, is linked to the perception of fiction. Check out the scathing reviews of the high frame rate version of "The Hobbit" for proof of that. Even if this perception seems grandiose -- the look of 24fps is expected with movies and fiction TV shows. Even though the TV and movie industries have been moving away from shooting on actual film, the new digital cameras are set for 24fps because the audience for fictional programming expects that look.

SOE messes with this cadence. By creating new frames between the 24 original frames, it causes it to look like 30fps or 60fps content. In other words, it makes movies (24fps) look like soap operas (30/60fps). And thus, a name is born.

By any other name
Every TV company has a different name for their motion interpolation processing. A sort list: Sony MotionFlow, Samsung Auto Motion Plus, Sharp AquoMotion, Toshiba ClearFrame or ClearScan, Vizio Smooth Motion, and LG TruMotion. I sense a theme.

While reducing motion blur is the main reason this processing exists, the (possibly) beneficial side effect is reducing the 2:3 judder noticeable on fast pans in 24fps content. The process of converting 24fps content for 60fps televisions involves a 2:3 sequence. The first frame is shown twice, the second frame three times, the third twice, and so on. Check out "1080i and 1080p are the same resolution" for a more detailed description. Because this sequence is, well, weird, camera pans can look jerky or juddery. Motion interpolation smooths this out. This is one of the reasons why some people prefer the SOE.

Nearly all companies allow you to disable SOE, and most allow you to adjust its intensity. Some separate out the blur reduction from the judder reduction, though personally I've found SOE at any level to be distracting.

Plasma
Up until recently SOE has been an LCD-only "issue." In the effort to make plasmas more competitive in a retail store, motion smoothing circuitry has found its way into plasmas. Because plasma TVs don't suffer from the motion blur problems that LCDs have (or at least, not to the extent), motion smoothing is largely superfluous. For that matter, plasmas aren't increasing their refresh rates to insert new frames, so all that's really happening is the TV is creating new frames to insert in-between the film frames, just to make the motion smoother.

Panasonic, for example, calls its version of this Cinema Smoother. On its LCDs, you can find it under "Motion Picture Setting."

This is how Panasonic explains its Cinema Smooth processing. Other company's processing works the similar to this diagram. Note the ' and " signifying the blue-boxed frames are different (interpolated).

Bottom line
The best part about the Soap Opera Effect is if you don't like it, you can turn it off. A few minutes digging though your TV's picture settings, and you should be able to find it. Get to know where this setting is (it's probably on the remote, too). It's possible you'll want it on when you're watching sports, or other "video"-based content (30fps or 60fps). Then, for movies and fictional TV programming, you can turn it off. This will give you the best-of-both worlds approach with minimal motion blur with sports, and no SOE with movies.

With plasma TVs, though, there is little penalty to turning this "feature" off. So go ahead.

Are Honeybees Losing Their Way?

A single honeybee visits hundreds, sometimes thousands, of flowers a day in search of nectar and pollen. Then it must find its way back to the hive, navigating distances up to five miles (eight kilometers), and perform a "waggle dance" to tell the other bees where the flowers are.

A new study shows that long-term exposure to a combination of certain pesticides might impair the bee's ability to carry out its pollen mission.

"Any impairment in their ability to do this could have a strong effect on their survival," said Geraldine Wright, a neuroscientist at Newcastle University in England and co-author of a new study posted online February 7, 2013, in the Journal of Experimental Biology.

Wright's study adds to the growing body of research that shows that the honeybee's ability to thrive is being threatened. Scientists are still researching how pesticides may be contributing to colony collapse disorder (CCD), a rapid die-off seen in millions of honeybees throughout the world since 2006.

"Pesticides are very likely to be involved in CCD and also in the loss of other types of pollinators," Wright said. (See the diversity of pollinating creatures in a photo gallery from National Geographic magazine.)

Bees depend on what's called "scent memory" to find flowers teeming with nectar and pollen. Their ability to rapidly learn, remember, and communicate with each other has made them highly efficient foragers, using the waggle dance to educate others about the site of the food source.

Watch as National Geographic explains the waggle dance.

Their pollination of plants is responsible for the existence of nearly a third of the food we eat and has a similar impact on wildlife food supplies.

Previous studies have shown certain types of pesticides affect a bee's learning and memory. Wright's team wanted to investigate if the combination of different pesticides had an even greater effect on the learning and memory of honeybees.

"Honeybees learn to associate floral colors and scents with the quality of food rewards," Wright explained. "The pesticides affect the neurons involved in these behaviors. These [affected] bees are likely to have difficulty communicating with other members of the colony."

The experiment used a classic procedure with a daunting name: olfactory conditioning of the proboscis extension reflex. In layman's terms, the bee sticks out its tongue in response to odor and food rewards.

For the experiment, bees were collected from the colony entrance, placed in glass vials, and then transferred into plastic sandwich boxes. For three days the bees were fed a sucrose solution laced with sublethal doses of pesticides. The team measured short-term and long-term memory at 10-minute and 24-hour intervals respectively. (Watch of a video of a similar type of bee experiment.)

This study shows that when pesticides are combined, the impact on bees is far worse than exposure to just one pesticide. "This is particularly important because one of the pesticides we used, coumaphos, is a 'medicine' used to treat Varroa mites [pests that have been implicated in CCD] in honeybee colonies throughout the world," Wright said.

The pesticide, in addition to killing the mites, might also be making honeybees more vulnerable to poisoning and effects from other pesticides.

Stephen Buchmann of the Pollinator Partnership, who was not part of Wright's study, underscored how critical pollinators are for the world. "The main threat to pollinators is habitat destruction and alteration. We're rapidly losing pollinator habitats, natural areas, and food-producing agricultural lands that are essential for our survival and well being. Along with habitat destruction, insecticides weaken pollinators and other beneficial insects."

'Blade Runner' Charged With Murdering Girlfriend

Oscar Pistorius, the Olympic and Paralympic athlete known as the "blade runner," was taken into custody in South Africa today and charged with the murder of his girlfriend, who was fatally shot at his home.

Police in the South African capital of Pretoria received a call around 3 a.m. today that there had been a shooting at the home of 26-year-old Pistorius, Lt. Col. Katlego Mogale told The Associated Press. When police arrived at the scene, they found paramedics trying to revive 29-year-old Reeva Steenkamp, the AP reported.

At a news conference early today, police said Pistorius was arrested and had requested that he be taken to court immediately.

The National Prosecuting Authority (NPA) said Pistorius' hearing will be Friday at 9 a.m. local time. His court hearing was originally scheduled for this afternoon but has been postponed to give forensics investigators time to carry out their work, NPA spokesman Medupe Simasiku said.

The precise circumstances surrounding the incident are unclear. Local reports say he might have mistaken her for a burglar, according to the AP.

Police said they have heard reports of an argument or shouting at the apartment complex, and that the only two people on the premises were Steenkamp and Pistorius.

Police confirmed there have previously been incidents of a domestic nature at the home of Pistorius.

Pistorius, a sprinter, had double below-the-knee amputations and a part of his legs has been replaced with carbon fiber blades. In 2012, he became the first double-leg amputee to participate in the Olympics, competing in the men's 400-meter race.

He also competed in the Paralympics, where he won gold medals in the men's 400-meter race, in what became a Paralympics record. He also took the silver in the 200-meter race.

Steenkamp, according to her Twitter bio, is a law graduate and model. She tweeted Wednesday, "What do you have up your sleeve for your love tomorrow??? #getexcited #ValentinesDay."

Steenkamp recently appeared on the cover of FHM magazine, in commercials and was due to appear on a reality-TV show, "Tropika Island of Treasure."
