From Our Vault: Busy Postman on Break, 1951

The United States Post Office announced this week that it intends to stop Saturday letter delivery beginning in August, 32 years after Congress mandated a sixth day of mail service.

First class mail volume has been dropping by about five billion pieces annually since 2007. And the USPS operated almost $16 billion dollars in the red in 2012.

In the 1950s, when this photo was taken, the federal agency was more flush with money. Five hundred thousand employees carried 54 billion items when National Geographic magazine published the article "Everyone's Servant, the Post Office" in July of 1954. Mail volume had doubled since the previous decade, and was growing at a rate of about seven percent a year.

This photo from 1951 didn't make it into that article, landing instead in the National Geographic image archive. Working during the postal boom years, this mailman delivering to houses in Hays, Kansas, likely didn't have time to notice the slight.

National Geographic photographer John E. Fletcher explained the mailman's decision to lunch in a mailbox in a note on the back of the photo.

"He told me that a new regulation from the Washington headquarters of the U.S. Post Office required that postmen while on delivery at noontime must stop and have their lunch at the spot, rather than taking time off to go home and eat," Fletcher wrote.

"This mailman told me that each day his wife would drive to this particular corner and meet him and hand him his lunch box," he continued. "The most convenient spot that he could find to eat his lunch was to open a storage mail box, get himself comfortably seated, and eat his lunch right on the street corner."

Editor's note: This is the first in a series of pieces that looks at the news through the lens of the National Geographic photo archives.

'Stay Home': Northeast Shuts Down as Blizzard Hits

A blizzard of possibly historic proportions is set to strike the Northeast, starting today and could bring more than two feet of snow and strong winds that could shut down densely populated cities such as Boston and New York City.

A storm from the west will join forces with one from the south to form a nor'easter that will sit and spin just off the East Coast, affecting more than 43 million Americans. Wind gusts will reach 50 to 60 mph from Philadelphia to Boston.

"[It] could definitely be a historic winter storm for the Northeast," Adrienne Leptich of the National Weather Service in Upton, N.Y., said. "We're looking at very strong wind and heavy snow and we're also looking for some coastal flooding."

The snow began falling in New York City shortly before 7 a.m. ET. The snow is expected to mix with some sleet and then turn back into snow after 3 p.m.

Airlines have started shutting down operations between 2 p.m. and 5 p.m. at major airports in the New York area as well as in Boston, Portland, Maine, Providence, and other Northeastern airports. More than 4,000 flights have been cancelled on Friday and Saturday, according to FlightAware. Airlines hope to resume flights by Saturday afternoon.

New York City is expecting up to 14 inches, which is expected to start this morning with the heaviest amounts falling at night and into Saturday. Wind gusts of 55 mph are expected in New York City and Cape Cod, Mass., could possibly see 75 mph gusts.

Winter Storm to Hit Northeast With Winds and Snow Watch Video

Boston, Providence, R.I., Hartford, Conn., and other New England cities canceled school today. Boston and other parts of New England could see more than 2 feet of snow by Saturday.

Massachusetts Governor Deval Patrick declared a state of emergency Friday afternoon and announced a ban on all traffic from roads after 4 p.m. It is believed that the last time the state enacted such a ban was during the blizzard of 1978.

Beach erosion and coastal flooding is possible from New Jersey to Long Island, N.Y., and into New England coastal areas. Some waves off the coast could reach more than 20 feet.

"Stay off the streets of our city. Basically, stay home," Boston Mayor Tom Menino warned Thursday.

Blizzard warnings were posted for parts of New Jersey and New York's Long Island, as well as portions of Massachusetts, Rhode Island and Connecticut, including Hartford, New Haven, Conn., and Providence. The warnings extended into New Hampshire and Maine.

To the south, Philadelphia was looking at a possible 4 to 6 inches of snow.

Thousands of flights have already been canceled in anticipation of the storm. Amtrak said its Northeast trains will stop running this afternoon.

Bruce Sullivan of the National Weather Service says travel conditions will deteriorate fairly rapidly Friday night.

"The real concern here is there's going to be a lot of strong winds with this system and it's going to cause considerable blowing and drifting of snow," he said.

Parts of New York, still reeling from October's Superstorm Sandy, are still using tents and are worried how they will deal with the nor'easter.

"Hopefully, we can supply them with enough hot food to get them through before the storm starts," Staten Island hub coordinator Donna Graziano said.

New York City Mayor Michael Bloomberg said plows and 250,000 tons of salt were being put on standby.

"We hope forecasts are exaggerating the amount of snow, but you never can tell," Bloomberg said Thursday.

Residents of the Northeast have already begun to hit stores for groceries and tools to fight the mounting snow totals.

The fire department was called in to a grocery store in Salem, Mass., because there were too many people in the store Thursday afternoon trying to load up their carts with essential items.

"I'm going to try this roof melt stuff for the first time," Ian Watson of Belmont, Mass., said. "Just to prevent the ice dam. ... It's going be ugly on that roof."

ABC News' Max Golembo and The Associated Press contributed to this report.

North Korea nuclear test could "tie hands" of South: Ban Ki-moon

UNITED NATIONS: UN leader Ban Ki-moon warned on Thursday that a nuclear test by North Korea could blow up hopes of an eventual reconciliation by "tying the hands" of the South's incoming president.

Ban, a former South Korean foreign minister, said incoming South Korean president Park Geun-Hye is "very much committed" to improving relations with North Korea.

"If they conduct this nuclear test, it may be the case that they are effectively tying the hands of the new president of Korea," Ban told a small group of reporters, including AFP.

"It may take a long time before any initiative between North and South can take place to normalise this relationship," he said, adding to international warnings to the isolated North.

Park will take over on February 25 from President Lee Myung-Bak, who warned on Thursday of "serious consequences" if Pyongyang stages the test.

The two sides have been divided since the end of the 1950-53 Korean war, and the 2010 sinking of a South Korean warship and a subsequent missile attack further escalated the rivalry.

A third test of an atomic weapon would be going in "the wrong direction" said Ban, highlighting UN resolutions that imposed tough sanctions after blasts in 2006 and 2009.

The UN Security Council has already threatened "significant" measures if North Korea stages a new breach of the resolutions. Ban said he has been discussing the North's moves "with key countries."

Ban said the Stalinist government should do more to help its people. "The humanitarian situation is dire in DPRK," Ban said, using the acronym of the North's official name, the Democratic People's Republic of Korea.

He said nations had not given money to UN humanitarian efforts in North Korea "because of this crisis and the very tense situation on the Korean peninsula."

Ban said he had been forced to use money from the UN's emergency fund to support relief efforts in North Korea, where there is again widespread hunger.

Suryanelli sex scandal: 17-year-old Kerala rape haunts Congress

KOTTAYAM: A day after an AICC spokesperson said the Congress high command will look into the allegations against Rajya Sabha deputy chairman P J Kurien in the Suryanelli sex scandal , the victim's mother sent a letter to Sonia Gandhi, seeking her intervention for an impartial probe.

In a letter faxed to the Congress president on Thursday, the victim's mother narrated the trauma her daughter and the family underwent over the years and how their demand for a probe into Kurien's involvement was not heeded . She said the Congress leadership's decision to support Kurien was disheartening and made it clear that during the early stages of the probe, her daughter had told investigators that Kurien was one of the accused. But they paid no heed.

A complaint lodged with then CM A K Antony also went unheeded. "This is heart-breaking . We think, madam, you being the mother of a daughter of similar age as my beloved younger one, will understand the sufferings of a mother. I cannot understand how you will be able to preserve the dignity and self-respect of women of this country by keeping such people in the leadership of the Congress," she said. She wrote she believed Kurien had exerted undue influence over investigating officials to escape punishment.

She said most investigating officers advised the family to spare Kurien. "But my child still stands by her word." She also said that her two daughters - the elder aged 36 and the victim, 33 -- remain unmarried. "We are ostracized and subjected to humiliation." She argues: "I wonder how can Kurien chair the discussion when the Ordinance for emancipation of womanhood promulgated on the prevention of sexual atrocities against women comes up in the Upper House? Such a situation will amount to tarnishing the image of your party, which has a glorious past in protecting the weaker sex. I humbly urge you to intervene."

Protests rock Kerala house

The Suryanelli gang-rape case continued to rock the assembly for the third day on Thursday, even as the government announced a judicial probe into allegations that two women MLAs were assaulted by the police on Wednesday. The announcement came after the opposition raised the matter in the House. The probe would look into whether the police had misbehaved with MLA Geetha Gopi or roughed up E S Bijimol, during their protest over the government's reluctance in acting against P J Kurien. Earlier, opposition MLAs C Divakaran, K K Lathika, Mathew T Thomas and A A Azeez moved an adjournment motion on the alleged police assault.CM Oommen Chandy termed Wednesday's protest unfortunate as it was against the convention that no protest marches would be held in front of the assembly. Expressing willingness to initiate the judicial probe, Chandy invited the opposition to jointly examine with the treasury benches the electronic proof of the incidents. He added that the police officers at the scene had not misbehaved with the MLAs. Rejecting the CM's arguments, the opposition demanded suspension of the police officers concerned before ordering an inquiry. "When the government itself feels that none of the police officers have done wrong, there is no point in having a judicial inquiry," Kodiyeri Balakrishnan, deputy leader of the opposition said.

Asteroid to Make Closest Flyby in History

Talk about too close for comfort. In a rare cosmic encounter, an asteroid will barnstorm Earth next week, missing our planet by a mere 17,200 miles (27,700 kilometers).

Designated 2012 DA14, the space rock is approximately 150 feet (45 meters) across, and astronomers are certain it will zip harmlessly past our planet on February 15—but not before making history. It will pass within the orbits of many communications satellites, making it the closest flyby on record. (Read about one of the largest asteroids to fly by Earth.)

"This is indeed a remarkably close approach for an asteroid this size," said Paul Chodas, a research scientist at NASA's Jet Propulsion Laboratory Near Earth Object (NEO) program office in Pasadena, California.

"We estimate that an asteroid of this size passes this close to the Earth only once every few decades."

The giant rock—half a football field wide—was first spotted by observers at the La Sagra Observatory in southern Spain a year ago, soon after it had just finished making a much more distant pass of the Earth at 2.6 million miles (4.3 million kilometers) away.

This time around however, on February15 at 2:24 pm EST, the asteroid will be passing uncomfortably close—ten times closer than the orbit of the moon—flying over the eastern Indian Ocean near Sumatra (map). (Watch: "Moon 101.")

Future Impact?

Chodas and his team have been keeping a close eye on the cosmic intruder, and orbital calculations of its trajectory show that there is no chance for impact.

But the researchers have not yet ruled out future chances of a collision. This is because asteroids of this size are too faint to be detected until they come quite close to the Earth, said Chodas.

"There is still a tiny chance that it might hit us on some future passage by the Earth; for example there is [a] 1-in-200,000 chance that it could hit us in the year 2080," he said.

"But even that tiny chance will probably go away within the week, as the asteroid's orbit gets tracked with greater and greater accuracy and we can eliminate that possibility."

Earth collision with an object of this size is expected to occur every 1,200 years on average, said Donald Yeomans, NEO program manager, at a NASA news conference this week.

DA14 has been getting closer and closer to Earth for quite a while—but this is the asteroid's closest approach in the past hundred years. And it probably won't get this close again for at least another century, added Yeomans.

While no Earth impact is possible next week, DA14 will pass 5,000 miles inside the ring of orbiting geosynchronous weather and communications satellites; so all eyes are watching the space rock's exact trajectory. (Learn about the history of satellites.)

"It's highly unlikely they will be threatened, but NASA is working with satellite providers, making them aware of the asteroid's pass," said Yeomans.

Packing a Punch

Experts say an impact from an object this size would have the explosive power of a few megatons of TNT, causing localized destruction—similar to what occurred in Siberia in 1908.

In what's known as the "Tunguska event," an asteroid is thought to have created an airburst explosion which flattened about 750 square miles (1,200 square kilometers) of a remote forested region in what is now northern Russia (map).

In comparison, an impact from an asteroid with a diameter of about half a mile (one kilometer) could temporarily change global climate and kill millions of people if it hit a populated area.

Timothy Spahr, director of the Minor Planet Center at Cambridge, Massachusetts, said that while small objects like DA14 could hit Earth once a millennia or so, the largest and most destructive impacts have already been catalogued.

"Objects of the size that caused the extinction of the dinosaurs have all been discovered," said Spahr. (Learn about what really happened to the dinosaurs.)

A survey of nearly 9,500 near-Earth objects half a mile (one kilometer) in diameter is nearly complete. Asteroid hunters expect to complete nearly half of a survey of asteroids several hundred feet in diameter in the coming years.

"With the existing assets we have, discovering asteroids rapidly and routinely, I continue to expect the world to be safe from impacts in the future," added Spahr.

Alleged Cop-Killer Has Calif. Region on Edge

The truck owned and driven by suspected cop killer Christopher Dorner during his alleged rampage through the Los Angeles area was found deserted and in flames on the side of Bear Mountain, Calif., this afternoon.

Heavily armed SWAT team members descended onto Bear Mountain from a helicopter manned with snipers today to investigate the fire. The San Bernadino Sheriff's Department confirmed the car was Dorner's.

Dorner, a former Los Angeles police officer and Navy reservist, is believed to have killed one police officer and injured two others early this morning in Riverside, Calif. He is also accused of killing two civilians on Sunday after releasing a scathing "manifesto" alleging grievances committed by the police department while he worked for it and warning of coming violence toward cops.

Heavily armed officers spent much of Thursday searching for signs of Dorner, investigating multiple false leads into his whereabouts and broadcasting his license plate and vehicle description across the California Highway System.

Around 3:45 p.m. ET, police responded to Bear Mountain, where two fires were reported, and set up a staging area in the parking lot of a ski resort. They did not immediately investigate the fires, but sent a small team of heavily armed officers up in the helicopter to descend down the mountain toward the fire.

The officers, carrying machine guns and searching the mountain for any sign of Dorner, eventually made it to the vehicle and identified it as belonging to Dorner. They have not yet found Dorner.

Late this afternoon, CNN announced that Dorner had sent a package containing his manifesto and a DVD to its offices.

Police officers across Southern California were on the defensive today, scaling back their public exposure, no longer responding to "barking-dog calls" and donning tactical gear outdoors.

Police departments have stationed officers in tactical gear outside police departments, stopped answering low-level calls and pulled motorcycle patrols off the road in order to protect officers who might be targets of Dorner's alleged rampage.

"We've made certain modifications of our deployments, our deviations today, and I want to leave it at that, and also to our responses," said Chief Sergio Diaz of the police department in Riverside, Calif., where the officers were shot. "We are concentrating on calls for service that are of a high priority, threats to public safety, we're not going to go on barking dog calls today."

Sgt. Rudy Lopez of the Los Angeles Police Department said Dorner is "believed to be armed and extremely dangerous."

Early Thursday morning, before they believe he shot at any police officers, Dorner allegedly went to a yacht club near San Diego, where police say he attempted to steal a boat and flee to Mexico.

He aborted the attempted theft when the boat's propeller became entangled in a rope, law enforcement officials said. It was then that he is believed to have headed to Riverside, where he allegedly shot two police officers.

"He pointed a handgun at the victim [at the yacht club] and demanded the boat," said Lt. David Rohowits of the San Diego Police Department.

Police say the rifle marksman shot at four officers in two incidents overnight, hitting three of them: one in Corona, Calif., and the two in Riverside, Calif.

Football: Bengtson lifts Honduras over US

SAN PEDRO SULA, Honduras: Jerry Bengtson scored in the 79th minute to give Honduras a 2-1 victory over the United States on Wednesday in the North American qualifying final-round opener for the 2014 Brazil World Cup.

The New England Revolution striker knocked in the decider, aided by a blunder from a US defensive unit with relatively few World Cup qualifying caps while American veteran Carlos Bocanegra was watching from the bench.

Juan Carlos Garcia netted a spectacular bicycle kick for Honduras to equalise in the 39th minute after the visitors had seized the lead on a goal by Tottenham's Clint Dempsey in the 36th.

The critical stretch began when Oscar Garcia pushed the ball past US defender Geoff Cameron, who plays for Stoke City in England.

US goalkeeper Tim Howard, who plays for English side Everton, came after the ball but Garcia flicked the ball past him into the empty penalty area where an onrushing Bengtson kicked it home before a sliding Omar Gonzalez could stop him.

Juan Carlos Garcia, a 24-year-old left back, made a spectacular bicycle-kick goal in the 39th minute that pulled Honduras level 1-1 at half-time.

Maynor Figueroa took a centering pass on the chest and deflected the ball into the crowded heart of the penalty area, where Garcia made an incredible somersault and followed with a hammering kick past Howard.

Dempsey put the Americans ahead 1-0 by taking a perfect lob centering pass from Jermaine Jones in full stride while leaping into the air on a run midway through the penalty area.

Without an instant's pause, Dempsey blasted the ball past Honduran goalkeeper Noel Valladares to open the scoring.

Other regional qualifiers on Wednesday find Jamaica at Mexico and Costa Rica at Panama.

The three top teams after Confederation of North, Central American and Caribbean Association Football (CONCACAF) round-robin matches will qualify for Brazil. The fourth-place team will face a team from Oceania for another berth.

CBI finds it difficult to close fodder scam cases

RANCHI: The CBI is facing tough time in taking the five cases of the fodder scam in which two former chief ministers of Bihar, Lalu Prasad and Jagannath Mishra were involved, to their logical end.

Special public prosecutors of the CBI dealing the five cases said by using the provisions of law and the loopholes both Prasad and Mishra had dragged the cases for years. Of the 53 cases, the CBI has finished trial and courts have convicted the accused in 43 cases in the past 17 years. The cases were lodged in Rs 900-crore scam in 1996 at the time of united Bihar.

The CBI officials and advocates, who were planning to end the trial of at least one of the five cases in 2012, are now doubtful if they will be able to end it even this year. Of the 10 cases in which trial has to be completed, five are related to Prasad.

"In one of the cases (RC 20) which is related to fraudulent withdrawal of around Rs 37 crore from the Chaibasa (West Singhbhum) treasury where the trial is at its fag end, Prasad is dragging it in the name of producing defence witnesses who are not in India. The way they are dragging the case by opposing the move of CBI in higher judiciary, we are doubtful about when the case will end," said a special public prosecutor.

The other four cases in which Lalu Prasad and other high profile people are accused includes RC 38, 47, 64 and 86

are at evidence stage. "If the high profile politicians don't drag the cases, we can expect judgment by end of this year or early next year," said a public prosecutor.

Humans Swap DNA More Readily Than They Swap Stories

Jane J. Lee

Once upon a time, someone in 14th-century Europe told a tale of two girls—a kind one who was rewarded for her manners and willingness to work hard, and an unkind girl who was punished for her greed and selfishness.

This version was part of a long line of variations that eventually spread throughout Europe, finding their way into the Brothers Grimm fairytales as Frau Holle, and even into Shakespeare's The Merchant of Venice. (Watch a video of the Frau Holle fairytale.)

In a new study, evolutionary psychologist Quentin Atkinson is using the popular tale of the kind and unkind girls to study how human culture differs within and between groups, and how easily the story moved from one group to another.

Atkinson, of the University of Auckland in New Zealand, and his co-authors employed tools normally used to study genetic variation within a species, such as people, to look at variations in this folktale throughout Europe.

The researchers found that there were significant differences in the folktale between ethnolinguistic groups—or groups bound together by language and ethnicity. From this, the scientists concluded that it's much harder for cultural information to move between groups than it is for genes.

The study, published February 5 in Proceedings of the Royal Society B, found that about 9 percent of the variation in the tale of the two girls occurred between ethnolinguistic groups. Previous studies looking at the genetic diversity across groups in Europe found levels of variation less than one percent.

For example, there's a part of the story in which the girls meet a witch who asks them to perform some chores. In different renditions of the tale, the meeting took place by a river, at the bottom of a well, or in a cave. Other versions had the girls meeting with three old men or the Virgin Mary, said Atkinson.

Conformity

Researchers have viewed human culture through the lens of genetics for decades, said Atkinson. "It's a fair comparison in the sense that it's just variation across human groups."

But unlike genes, which move into a population relatively easily and can propagate randomly, it's harder for new ideas to take hold in a group, he said. Even if a tale can bridge the "ethnolinguistic boundary," there are still forces that might work against a new cultural variation that wouldn't necessarily affect genes.

"Humans don't copy the ideas they hear randomly," Atkinson said. "We don't just choose ... the first story we hear and pass it on.

"We show what's called a conformist bias—we'll tend to aggregate across what we think everyone else in the population is doing," he explained. If someone comes along and tells a story a little differently, most likely, people will ignore those differences and tell the story like everyone else is telling it.

"That makes it more difficult for new ideas to come in," Atkinson said.

Cultural Boundaries

Atkinson and his colleagues found that if two versions of the folktale were found only six miles (ten kilometers) away from each other but came from different ethnolinguistic groups, such as the French and the Germans, then those versions were as different from each other as two versions taken from within the same group—say just the Germans—located 62 miles (100 kilometers) away from each other.

"To me, the take-home message is that cultural groups strongly constrain the flow of information, and this enables them to develop highly local cultural traditions and norms," said Mark Pagel, of the University of Reading in the U.K., who wasn't involved in the new study.

Pagel, who studies the evolution of human behavior, said by email that he views cultural groups almost like biological species. But these groups, which he calls "cultural survival vehicles," are more powerful in some ways than our genes.

That's because when immigrants from a particular cultural group move into a new one, they bring genetic diversity that, if the immigrants have children, get mixed around, changing the new population's gene pool. But the new population's culture doesn't necessarily change.

Atkinson plans to keep using the tools of the population-genetics trade to see if the patterns he found in the variations of the kind and unkind girls hold true for other folktale variants in Europe and around the world.

Humans do a lot of interesting things, Atkinson said. "[And] the most interesting things aren't coded in our DNA."

Galaxy May Be Full of 'Second Earths'

You may look out on a starry night and get a lonely feeling, but astronomers now say our Milky Way galaxy may be thick with planets much like Earth -- perhaps 4.5 billion of them, according to the Harvard-Smithsonian Center for Astrophysics.

Astronomers looked at data from NASA's Kepler space telescope in orbit, and conclude that 6 percent of the red dwarf stars in the Milky Way probably have Earth-like, habitable planets. That's a lot by space standards, and since red dwarfs are very common -- they make up three out of four stars in our part of the galaxy -- we may have a lot more neighbors than we thought.

The nearest of them, astronomers said today, could be 13 light-years away -- not exactly commuting distance, since a light-year is six trillion miles, but a lot closer than most yellow stars like Earth's sun.

Video: Are We Alone? Kepler's Mission

David A. Aguilar/Harvard-Smithsonian Center for Astrophysics

"We thought we would have to search vast distances to find an Earth-like planet. Now we realize another Earth is probably in our own backyard, waiting to be spotted," said Courtney Dressing, an astronomer at the Harvard-Smithsonian Center, in announcing the findings today. The results will be published in The Astrophysical Journal.

David Charbonneau, a co-author, said, "We now know the rate of occurrence of habitable planets around the most common stars in our galaxy. That rate implies that it will be significantly easier to search for life beyond the solar system than we previously thought."

Red dwarfs are older, smaller and dimmer than our sun, but a planet orbiting close to one could be sufficiently warmed to have liquid water. Dressing and her colleagues cited three possible planets that were spotted by Kepler, which was launched in 2009. One is 90 percent as large as Earth, and orbits its red sun in just 20 of our days.

There is no saying what such a world would actually be like; the Kepler probe can only show whether distant stars have objects periodically passing in front of them. But based on that, scientists can do some math and estimate the mass and orbit of these possible planets. So far, Kepler has spotted more than 2,700 of them in the small patch of sky it has been watching.

There are estimated to be 200 to 400 billion stars in the Milky Way -- which is probably a pretty average galaxy. So the new estimate implies a universe with tremendous numbers of Earth-like planets, far beyond our ability to count.

Could they be friendly to life? There's no way to know yet, but space scientists say that if you have the right ingredients -- a planet the right size, temperatures that allow for liquid water, organic molecules and so forth -- and the chances may be good, even on a planet that is very different from ours.

"You don't need an Earth clone to have life," said Dressing.
