[Updated at 1:11 p.m. ET] Rescuers tunneling Friday into the rubble of the eight-story building that collapsed Wednesday discovered another 50 people trapped on what remained of its third floor, an official said.
Bangladesh Fire Service Deputy Director Maj. Mizamur Rahman said rescuers were hoping to free them within a few hours.
Also Friday, two women who gave birth under the debris were rescued – along with their infants – a fire service official said, according to BSS.
China’s first comprehensive measurement of its Great Wall shows it to be 13,170 miles long – thousands of miles longer than previous estimates – state news outlet Xinhua reported this week.
The length of the Great Wall of China – actually a non-contiguous series of defensive systems involving walls, natural barriers and trenches, built from 475 B.C. to 1644 in various areas to fend off invaders – was determined through surveys that began in 2007 at the direction of the State Administration of Cultural Heritage.
Partial results of the survey, announced in 2009, showed that the wall systems built during the Ming Dynasty (1368-1644) were 5,499 miles (8,851 kilometers) long, Xinhua reported.
Teams then were instructed to identify and measure pre-Ming Dynasty wall systems throughout China. They found them to be 7,671 miles (12,345 kilometers) in length, said British researcher and author William Lindesay, who studies the Great Wall.
“The figure just announced (13,170 miles, or 21,196 kilometers) is a combination of the length of the Ming plus (the) length of pre-Ming Great Walls,” Lindesay wrote to CNN in an e-mail Wednesday.
The British Broadcasting Corp. reported in 2009 that before the initial survey results were announced, the wall’s length was commonly estimated at about 3,100 miles (5,000 kilometers).
Tens of thousands of visitors flocked to the Tokyo Skytree on Tuesday, trying to be among the first people to get a view of the Japanese capital from the world's tallest tower.
The Skytree rises 634 meters (2,080 feet) above Tokyo. It was certified as the world's tallest tower by Guinness World Records on November 17, according to the Skytree's website.
Guinness lists the Burj Khalifa in Dubai, at 828 meters (2,716 feet 6 inches), as the world's tallest building.
The distinction is that Burj Khalifa is an occupied building. The Skytree is a broadcast structure, with digital transmissions for Tokyo media beamed from it. Its towering height doubles the coverage that was previously available, as it enables signals to get past the countless other skyscrapers in the Japanese capital, according to the Skytree website.
People showing up for trips up the Skytree were beaming with pride and excitement Tuesday, according to local news reports.
Saudi Arabia's Kingdom Holding has hired Saudi Bin Laden Group to build the world's tallest skyscraper in Jeddah, Gulfnews.com reports.
Jeddah Tower will be 1,000 meters (3,281 feet) tall and will contain a Four Seasons luxury hotel, apartments, condominiums and offices that overlook the Red Sea, Financial Times reported.
Kingdom Holding is paying Bin Laden Group, one of the world's largest construction companies, about $1.2 billion to take on the five-year project, according to Financial Times.
Saudi Bin Laden Group was founded in 1931 by Muhammad Awad bin Laden, the billionaire father of terrorist Osama bin Laden. It built much of Saudi Arabia's highways and infrastructure, as well as entire districts and cities.
The company constructed additions to the Muslim nation's two holiest mosques in Mecca and Medina. It operates throughout the Middle East and was chosen in 1964 to reclad the golden Dome of the Rock mosque in Jerusalem.
Over the years, Saudi Bin Laden Group has expanded into a conglomerate that includes engineering, manufacturing and telecommunications, according to business analysis site Hoovers.com.
Osama bin Laden, the 17th of 52 children, inherited part of his father's fortune, but his radical activities led the family to disown him in 1994.
Prince Alwaleed Bin Talal Bin Abdulaziz Alsaud, a nephew of Saudi Arabia's King Abdullah, announced the tower building contract Tuesday. He owns 95% of Kingdom Holding, according to Financial Times.
When completed, Jeddah Tower will easily surpass Dubai's 828-meter (2,717-foot) Burj Khalifa as the world's tallest building.
The Chicago firm Adrian Smith + Gordon Gill Architecture designed the project and will oversee its development, Gulfnews.com reported. Adrian Smith was one of Burj Khalifa's designers when he was with Skidmore Owings and Merrill.
If you have always wanted the tallest house in your neighborhood, here's your chance.
The federal government is auctioning off three decommissioned lighthouses, and the bids are still pretty low.
As of Tuesday morning, the Kenosha North Pierhead Light in Wisconsin is sitting at $13,000. In Ohio, three bids for the Fairport Harbor West Breakwater Light have risen to $39,500. The bidding ends Wednesday for both.
For years, women across America have dealt with glass ceilings. But now, women in Ohio have a new problem - glass floors.
A $105 million courthouse opened in Franklin County, Ohio, on Monday, but the builders seemed to have forgotten one thing - the bottom of the stairs, reports affiliate 10TV. The staircase is made of glass.
Dress wearers need to avoid taking the stairs, according to Franklin County Judge Julie Lynch, who wears dresses under her robes almost every day.
"I wear dresses because that's my personal choice," Lynch told 10TV. "When you stand under the stairwell, you can see right up through them.”
She speculates that men, who didn’t take half the population into account, designed the stairs.
Attorney Lori Johnson was startled by the transparent stairs. She worries not only about stares, but also how many cell phones have cameras attached.
“The next thing you know, you’re on the internet,” Johnson said, according to 10TV. “It sounds like a lawsuit in the making.”
While security guards warn women about taking the stairs, it seems most are just hoping people will be mature about the situation.
"They hope people will be mature? That's not a solution," Lynch said to 10TV. "If we had mature people that didn't violate the law, we wouldn't have this building."
Editor's Note: CNN's Soledad O'Brien and Rose Marie Arce were given rare access last week to the entire complex under construction at ground zero for an upcoming CNN documentary, "Beyond Bravery: The Women of 9/11." Here are their impressions after touring the site:
New York (CNN) - You have to walk downhill to get into ground zero, which is an odd feeling because the World Trade Center complex was all about looking up.
It looks like a noisy, massive construction zone from the outside, but inside you can see how much progress has been made as the 10th anniversary of September 11 approaches.
The public has gotten few glimpses of what's unfolding here, mostly during ceremonies or when dignitaries have visited or the waterfalls were tested.
Filmmakers, photographers and historians duck in to gather material they will unveil in the future. Architect Michael Arad, survivor of a bruising process to design a 9/11 memorial, says he gives occasional interviews alongside the memorial. The folks who work here are very protective of this site.
But last week, Arad gave us a rare tour of the entire complex.
Thirty-eight years ago Monday, the World Trade Center opened its doors.
At the time, the grandiose structures known as Building 1 and Building 2 were the tallest skyscrapers in the world.
New Yorkers' reaction to the towers were mixed. "Public sentiment ran from astonishment at the sheer size of the towers, to both thrill and dismay at their monolithic, modern design," according to WTC.com.
The ol' cut and run - An Oklahoma man is accused of stuffing a chainsaw down his pants and running. Well, waddling is likely a better word. The best part about this absurd story is the repeated use of the term "britches" and the infamous local news standby – the old camera man re-enactment routine.
The year in implosions - Here at CNN, we get a glut of videos in surprising categories. All this week on "Gotta Watch," we will be unveiling short compilations of some of our favorites, including the demolition of the stadium that the Dallas Cowboys once called home (pictured above). As one of Newton’s laws explains, what goes up, must come down. Here’s a look at some of the best examples of 2010:
A giant toilet was the centerpiece of a protest earlier this year in London, England.
"Today, you can talk about POOP out in the open," the One Campaign trumpeted on Twitter.
Friday is World Toilet Day, an observance guaranteed to elicit giggles.
But the day has a serious purpose: Organizers call it "a day to celebrate the importance of sanitation and raise awareness for the 2.6 billion people (nearly half of the world's population) who don't have access to toilets and proper sanitation." FULL POST

Wool bricks are 37 percent stronger than regular bricks, researchers say.
You’ve got more wool, clay and seaweed than you know what to do with. Here’s a solution: Make really strong bricks.
Researchers in Spain and Scotland say they’ve done just that.
In experiments conducted at the University of Seville in Spain and the University of Strathclyde in Glasgow, Scotland, researchers added wool fibers to the claylike soil used to make bricks, then threw in alginate conglomerate, a polymer made from seaweed, according to a study published in the journal Construction and Building Materials.
Two teens were arrested in the Tuesday fire at Hastings Pier.
Britain’s renowned Hastings Pier, a Victorian-era structure once dubbed the “Peerless Pier,” was 90 percent destroyed by fire early Tuesday.
Two local men, ages 18 and 19, were arrested on suspicion of arson after the blaze, according to the Hastings Observer.
The pier, which opened in 1872 as a holiday destination for tourists, was the work of Eugenius Birch, who designed 14 similar piers across Britain. Only seven remained before Tuesday’s fire, according to the Hastings Pier and White Rock Trust.
The MAXXI museum of contemporary Art in Rome
One of architecture's most prestigious prizes has gone to the MAXXI museum of contemporary art and architecture in Rome, Italy.
The Stirling Prize went to MAXXI's creator, noted architect Zaha Hadid. The London-based Iraqi recently completed work on the Aquatics Centre for the London 2012 Olympics. In 2004, Hadid became the first woman to win the Pritzker Prize, the highest honor in architecture.
