Well-known for historic architecture and chocolates, Lviv, Ukraine's official capital of culture, looks, smells, and tastes like the best of Europe. Indeed, its western flavor has earned it the title "Little Paris of Ukraine".

    For centuries Lviv, located 50 kilometers from the Poland-Ukraine border, was an important stopping point on the main trade routes between the east and west. During the Renaissance, the city could afford Italy's finest architects because every merchant passing through was forced to stay and sell their goods for at least two weeks. "It was a very smart move to collect money from them," said Yaroslav Hrytsak, a local historian, adding, "It kept the wealth in the city, and that wealth has been transformed into architectural richness."

    Many historic buildings remain but Lviv's prosperity didn't survive its bloody history. Over the centuries, the city fell under the rule of Poland, Austria, Austria-Hungary, Russia and the Nazi Germany. In addition, both Sweden and Turkey tried unsuccessfully to conquer the city. Then for almost half a century Lviv was ruled by the Soviet Union (苏联). With that, the city was condemned to relative obscurity(无闻). But recently things have started to change. Lviv experienced a sudden 40% increase in tourism in early2010, which was the highest rate in Europe. Just last month, its gates opened even wider, when Lviv became a host city for the Euro 2012 football championships.

    So how has this happened? With the Soviet collapse, some saw new opportunities for reviving Lviv's former wealth and fame.

    Limelight networks is a US-founded company. It's one of many digital tech firms to have opened offices in Lviv over the past few years. "It had good growth and experience in the US, however, the company needs more talent to do the new cool projects and products for our customers. This is why we're here in Ukraine." said CEO of Limelight networks.

    Lviv's unexpected abundance of I.T. talent is in fact a legacy(遗产) of the former Soviet Union. To help the military, many Soviet universities focused on turning out world-class engineers and Lviv's university is still producing them. Now, the city is home to 23 higher education institutions. It's clear that the city of Lviv does not intend to remain a hidden jewel for much longer.

    How many times do you check your Moments or Facebook page in a day to see whether your latest post has got another “like” or “thumbs up”?

    Although you might be embarrassed to admit how many times you do this, don't worry. Psychological findings have shown it's completely normal.

    In fact, the pleasure we derive from (取自) getting a “like” is equal to that of eating chocolate or winning money, and we can't help wanting more.

    According to the findings of the UCLA Brain Mapping Center, which observed 32 teens aged between 13 and 18, the feedback circuit (反馈电路) in the teens' brains are particularly sensitive, and the “social” and “visual” parts of their brains were activated when they received “likes” on a social network. The research also showed that though the thumbs up might come from complete strangers, the good they derive from it worked equally.

    So does it mean we should try our best to win as many thumbs up as possible?

    Not necessarily so if we know the reasons behind our desire for attention.

    In “Why do people crave (渴望) attention” by M. Farouk Radwan, he explained several cases in which people naturally longed for attention. Radwan said people who were an only child, who were used to being the center of attention in their house, may try to reproduce these conditions. Feeling “overlooked and unappreciated” might also lead you to be eager for attention. Other times, the state of being jealous or wanting to cover your mistakes may also contribute to such longings.

    In fact, too much desire for attention can create anxiety, and in turn ruin your happiness even when you get it. So what can we do about it? The answer is quite simple.

    “If people could adopt goals not focused on their own self-esteem (自尊) but on something larger than their self, such as what they can create or contribute to others, they would be less sensitive to some of the negative effects of pursuing self-esteem,” wrote psychology professor Jennifer Crocker in the Journal of Social Issues.

    A person can use all five senses while spending time with dolphins. We can see them play in the waves, hear them call, and feel their skin. Dolphins can sense you, too, but not in all the same ways. They have good eyesight, for example, but no sense of smell. Sensory biologists try to understand connections between animal behaviors and the senses. One team of these scientists recently made an unexpected discovery about certain dolphins.

    The researchers found that Guiana dolphins can detect electric fields, an ability that may help them find fish to eat. The secret to this newly found sense, say the scientists, is hidden in the dolphins' snouts (口鼻部).

    "We were really surprised to find this in the dolphin. Nobody had expected it," said Wolf Hanke, who led the new dolphin study.

    Hanke and his team suspected the dolphin's electro－sense might have something to do with small dimples (酒窝) on the animal's snout. "We thought they must have some functions," Hank said. To find out for certain, his team studied two Guiana dolphins.

    The scientists first studied the dimples of a 29－year－old dolphin that had died of natural causes. Under a microscope, the dimples looked familiar: they were similar to the sensors used by other animals to detect electric fields.

    Next, Hanke and his team tested a live dolphin, a 28－year－old named Paco, to see if he could recognize an electric field. They taught Paco to swim close to a device that could create a weak electric field in the water. Then the team taught Paco to swim away from the device if he detected any changes. When the scientists created an electric field, Paco swam away—showing that he knew something had changed. When there was no electric field, Paco stayed there. When Paco's snout was covered in plastic, he didn't react to the electric field.

    Paco's behavior told the scientists that the dolphin used his snout to detect the tiny electric field. "This is a major breakthrough," Peter Madsen, a sensory biologist, said.

    Situated in the heart of Beijing, the Forbidden City－now called the Palace Museum－covers an area of 1,120,000 square meters.

Owls and Larks

    Larks are most likely to be healthy, wealthy and wise, according to the old saying.

    But those who are early to bed and early to rise do not always have the upper hand, researchers say. They have found that night owls are generally brighter and wealthier than those able to get up early in the morning.

    Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late proved the kind of intelligence associated with honored jobs and higher incomes. "Larks" or "morning people", however, often acquired better exam results, possibly because lessons are held at the wrong time of day for night owls. The researchers examined the habits and body clocks of the youngsters to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their peak in the morning. School performance and inductive(归纳的)intelligence, or problem solving, were measured and academic grades in the major subjects were also taken into account. The results showed that evening types scored higher than morning types on inductive reasoning, which has been shown to be a good estimate of general intelligence and a strong indicator of academic(学术的) performance. They also had a greater capacity(能力) to think conceptually(概念地) as well as analytically. Such abilities have been linked to innovative(创新的) thinking, more admired occupations and better incomes.

    Famous night owls include President Trump, Obama, Charles Darwin, Winston Churchill, Keith Richards and Elvis Presley. George W. Bush, who is regularly in bed by 10 p.m., Thomas Edison, Napoleon, Condoleezza Rice, who wakes at 4:30 a.m., and Ernest Hemingway are among those known as larks. Jim Horne, professor of psychophysiology at Loughborough University, said, "Evening types tend to be the more active and creative types, the poets, artists and inventors, while the morning types are the deducers(推导者), as are often seen with civil servants and accountants." A previous study of US Air Force recruits found that evening types were much better at thinking to solve problems than larks.
