Q: (CNN) -- One of the most highly anticipated apps for Apple devices was made available on Wednesday. At least, until it wasn't. Google announced a Gmail app for the iPhone, iPad and iPod Touch that was designed to make it easier for the service's more than 190 million users to navigate their mail. "We check email pretty much everywhere these days," Google content manager Matthew Izatt wrote on the Gmail blog. "And when we do, we want easy access to our important messages so we can respond quickly and get back to life -- or slinging birds at thieving green pigs." Users of Apple's operating system could already access Gmail through a mobile site or set it up as their default e-mail account. But the new app promised a smoother experience with a host of new features. The tech blogosphere was delighted. "Go get the iPhone app for Gmail!" popular blogger Robert Scoble wrote on his Google+ page. Then, a few minutes passed. "UPDATE: DO NOT. The Gmail app is really a piece of crud," he wrote. "Not worth loading. Very disappointed." Google had obviously already noticed what Scoble did. Shortly after it was unveiled, the app was pulled from the Apple Store. "The iOS app we launched today contained a bug with notifications," Google posted on its Gmail Twitter account. "We have pulled the app to fix the problem. Sorry we messed up." Later, a fuller explanation was added to the original blog post. "Earlier today we launched a new Gmail app for iOS," Google posted. "Unfortunately, it contained a bug which broke notifications and caused users to see an error message when first opening the app. We've removed the app while we correct the problem, and we're working to bring you a new version soon. Everyone who's already installed the app can continue to use it." The app ... at least the fully working version of it ... will send push notifications and sound cues when new messages are received, search your inbox for an e-mail, autocomplete e-mail addresses and upload photos to messages. It will also feature the same Priority Inbox that Gmail's Web version has and add a new mobile interface that will allow users to navigate their inbox more quickly with touch controls. There was no word from Google Wednesday afternoon as to when the fixed app might be back up.

Q: ISTANBUL, Turkey (CNN) -- It's a common sight in the traffic-clogged streets of Istanbul, a city that straddles two continents. Workers next to the spot where subway trains will one day emerge from the tunnel. Opening of the tunnel has been delayed by at least four years by the discovery. A taxi driver, enraged by perpetually gridlocked traffic, stepping out of his car and yelling "Maniac!" at the man driving the public bus behind him. For decades Istanbul has been growing at a breakneck speed; its population exceeding -- by some estimates -- 15 million people. Too bad traffic often moves at a snail's pace. Most residents are quick to tell visitors the city's transport system is overwhelmed. "Istanbul is a dynamically changing city, every year increasing in population," says Zeynep Buket, an engineer working with Turkey's transportation ministry. "We are in need of radical systems, and this radical system is a mass transit system." The "radical system" city planners embarked on five years ago involved construction of a new subway tunnel beneath the Bosphorus Strait, the spectacular body of water that cuts this city in two. By the year 2025, engineers predict more than one million people a day will use the tunnel to travel between Istanbul's Asian and European shores. "We will connect two continents, Asia and Europe," said Nusret Ilbay, one of the many engineers working on the $3 billion Marmaray Tunnel Project. He was standing on scaffolding, overlooking a gaping 30-meter deep hole that will one day be a subway station on the Asian side of the Bosphorus. A concrete wall is all that holds back a churning river of sea water. Watch video of the tunnel being constructed . "As you can see, some leakage on the wall face has been observed," Ilbay explained on a tour of the construction site. "In order to overcome these leakages, we have applied chemical grouting." Legend has it, thousands of years ago Jason and the Argonauts narrowly escaped death sailing up the Bosphorus in search of the mythological Golden Fleece. Today, engineers face equally daunting challenges building a tunnel beneath one of the world's busiest shipping channels, at depths of up to 55 meters, in an active earthquake zone. First they dredged a trench on the bottom of the Bosphorus. Then, using divers and undersea cameras, they submerged and buried 11 massive pre-fabricated tunnel segments, almost all of them longer than a football field. To enter the unfinished tunnel, visitors must climb down a steep staircase in a construction tower surrounded by water in the middle of the strait. During the descent, the temperature plummets and humidity rises. Construction workers toil here in the gloom of this 1.4 kilometer long tube on the bottom of the sea, their welding torches spraying showers of sparks in the darkness. One worker claimed that during the lunch break, when the machinery came to a stop, he could hear the sound of oil tanker and cargo ships' engines as they motored past in the waters overhead. As a precaution in the event of a catastrophic flood in the tunnel, engineers constructed an emergency bunker on the bottom of the sea. Stocked with food and water and equipped with a heavy water-proof door, the "emergency room" is supposed to protect survivors for up to 10 days, until they can be rescued. But, in their rush to modernize Istanbul's transport system, city planners ran into an unforeseen obstacle: history. In Yenikapi, a neighborhood of textile factories and seedy hotels where one of the main transit stations for Istanbul's new subway and commuter rail system was to be built, archaeologists discovered the lost Byzantine port of Theodosius. It was originally built at the end of the 4th century AD by Emperor Theodosius I  when Istanbul -- then known as Constantinople -- was the capital of the eastern Roman Empire. The port's harbor silted over centuries ago, and eventually disappeared beneath subsequent layers of civilization. Until its rediscovery in 2004, archaeologists said they only knew about the port from ancient books. "This was a big moment of joy and happiness for us, an unexplainable feeling," recalls Professor Zeynep Kiziltan, the acting director of Istanbul's Archaeology Museum.  Look at pictures of the excavation » . "At around one meter below sea level, we started finding the remains of ropes. As we continued [digging] a bit more, the remains of a boat surfaced." Since that discovery, armies of hundreds of laborers and archaeologists have been working in a giant pit, three shifts a day, seven days a week. The scale of the excavation is unusual in modern-day archaeology, says Cemal Pulak, an anthropologist from Texas A&M University's nautical archaeology program. Look at a map of the site . "Its mind-boggling ... it really looks like an Indiana Jones-type operation," says Pulak, who has worked as a consultant on the excavation of the lost port. The Yenikapi dig has uncovered an ancient armada: 34 Byzantine ships ranging from dating between the 7th and 11th centuries AD. In one tent, two workers carefully uncover the ancient wooden beams of a 40-meter long merchant vessel. A third man preserves the wood by keeping it moist, sprinkling the relics with water from a hose. Archaeologists have nicknamed this ship "The Titanic," because it is the largest of the Theodosius wrecks. It is believed the vessel once carried wheat from Egypt to Constantinople. Scattered around the ship are shards of pottery, animal bones, and thousand-year-old clamshells. Historians say the new discoveries include the first examples of ships being built using the beginnings of the "skeleton approach" to constructing the vessel's hull. Pulak says that marked a revolutionary change which transformed shipbuilding from "mostly an art form to a science." "The earlier methods of building depended on verbal transference of the method from master shipbuilders to apprentices," he explained. "The development of the latter method ... allowed for the speedy communication of new shipbuilding ideas that could be transmitted on paper. It is the beginning of engineering. Ships could be preconceived and pre-designed." "I think it is one of the unique projects not only for us but for the world," said geologist Yucel Yilmaz. In addition to finding the timbers of thousand-year-old jetties and docks, which still jut up in straight rows at the bottom of the mammoth pit, archaeologists have uncovered the remnants of a pre-historic human settlement. "The first man, about 8,400 years ago, came and started to settle here," Yilmaz said. "There was no Bosphorus [then]. The Bosphorus was a river valley... the people who settled here walked across the Bosphorus." Plans to travel beneath the Bosphorus have been delayed at least four years by the excavation of the Theodosious Port. The postponement has added untold millions of dollars have also been added to the cost of the entire project. In the rush to move forward, the residents of Istanbul have accidentally uncovered a valuable piece of their city's ancient past.

Q: (CNN) -- The simple answer to the question why Pope Francis is headed to South Korea, in the first papal trip to Asia in 25 years, is straightforward. The pope is going to celebrate the sixth Asian Youth Day and beatify 124 martyrs of Korea. But the more complex answer has to take into consideration the Korean Catholic Church's unique history and the pope's theological agenda. These can give us a deeper understanding of why he is making this trip. While South Korea may not be viewed as an overtly Catholic nation (compared to the Philippines, the most Christian nation in Asia), at least 10% of South Korea's population belong to the Church, according to its statistics. The Catholic Church in Korea enjoys a high level of respect from non-Catholics, maintains good relations with other religious communities, and has a history of positive social engagement for the common good. Pope Francis's visit will recognize these accomplishments, a move that will not only please Koreans, but hold up their church as a model of evangelization. Evangelizing in Asia . Since it is Asia that has the greatest potential for the growth of Catholicism, it makes sense to highlight an Asian success story and to recognize the Asian youth who will be called on to continue that growth. Evangelization is in fact a key concern for Pope Francis. His apostolic exhortation, Evangelii Gaudium, focused on this topic and called for the transformation of the Catholic Church to focus on "the evangelization of today's world rather than for her self-preservation." The pope's concept of evangelization does not focus simply on baptizing new Catholics, but, as seen in the chapter from that exhortation entitled "The Social Dimension of Evangelization," also includes a call for the inclusion of the "homeless, the addicted, refugees, indigenous peoples, [and] the elderly who are increasingly isolated and abandoned." Moreover, this pope, while recognizing the importance of ordained clergy, decried "clericalism" before the publication of this exhortation, sees the laity as having an active role in evangelization. The pope's concerns as expressed in Evengelii Gaudium therefore resonate with the historical accomplishments of the Korean Catholic Church in that it has grown into a relatively large and healthy Catholic community with much of the work of evangelization being conducted by the laity. It is no accident that during his trip the pope will visit Kkottongnae (Flower Village), a Catholic institution devoted to caring for such marginalized groups as the elderly and the homeless, where he will meet with leaders of the Apostolate of the Laity. Origins of Korean Catholic Church . The Korean Catholic Church began with the baptism of a Korean scholar named Yi Seung-hun in Beijing in 1784, who had developed an interest in Catholicism after reading Chinese books on the religion. After his baptism, Yi returned to Korea and began baptizing others, so that there were already 4,000 Catholics there before a missionary -- a Chinese priest named Father James Zhou Wen-mo, himself one of the martyrs to be beatified -- arrived in 1794. The Korean state could not tolerate the existence of a foreign religion whose members recognized a deity outside government control and persecuted the new church. Catholics were given the choice of giving up their religion or being sentenced to death, with several thousands choosing the latter and becoming martyrs. Despite these persecutions, the church managed to survive and rebuild itself multiple times. While foreign missionaries played an important role, much of the work of maintaining the community and spreading the faith was carried out by the laity. The coming of religious tolerance in the late 19th century led to an increase in the number of Catholics, but it was not until the 1960s that the Catholic Church in Korea began to grow quickly. While that growth has slowed down in recent years, the church is quite healthy, with its approximately five million members, according to the church. At the same time, it must be stressed that the Korean Catholic Church faces challenges. Growth has declined, and many newly baptized Catholics leave the faith or become lukewarm. Likewise, Korean society has many of the difficulties post-industrial societies in the West face, such as the "unbridled consumerism" the pope decried in his apostolic exhortation. It is here that one can see the importance of the martyrs who the pope will beatify. In their stories, one sees Catholics giving up wealth, sex, and even life itself out of their love for others and for God. The pope will no doubt highlight how their devotion to the faith led to the growth and development of the Catholic Community in Korea, allowing him to echo the themes found in his exhortation. The fact that he will beatify these martyrs in Korea the day after Koreans celebrate their independence from Japan, will not be missed by Koreans. The pope likely hopes that this recognition, and the teaching opportunity it provides, will renew evangelization in Korea, and through it, the world.

Pope is to celebrate sixth Asian Youth Day and beatify 124 martyrs of Korea .
Asia that has the greatest potential for the growth of Catholicism .
