A team of UK researchers recently compared the performances of 120 women and 120 men in a computer test involving switching between tasks of counting and shape recognition.

    Men and women were equally capable when tasks were handled one at a time. But when the tasks were mixed up, there was a clear difference. According to the paper published in the journal BMC Psychology, both women and men slowed down and made more mistakes as the switching became more rapid. But the men were slower, taking 77 percent longer to answer, whereas women took 69 percent longer.

    To make the experiment more relevant to day-to-day life, researchers tried a second test. A group of women and men were given eight minutes to complete a series of everyday tasks, such as finding restaurants on a map, doing simple math problems, answering a phone call, or deciding how they would search for a lost key in afield. Once again, women outperformed men in the test, particularly in the key-searching task.

    “It suggests that in a stressed and complex situation women are more able to stop and think about what's going on in front of them,” researcher Keith Laws of the University of Hertfordshire, UK, told BBC News. “In contrast, men had a slight impulsiveness（冲动）, answering without giving much thought to their responses.”

    So where do women get the ability to keep organized under pressure better than men? Researchers believe that it has its roots in evolution. In early human communities, women had to keep an eye on children while cooking meals. Meanwhile, men only needed to focus on hunting.

    In a world with limited land, water and other natural resources (资源), the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.

    Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.

    The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

    Almost every light comedy or situation comedy makes me feel like I should be drinking wine every night with my best friend while one of us tries on clothes. Not only should we share the same dress size, but we should also have a long, rich history of togetherness and secrets. Clearly, this is not reality.

    I have 598 friends. OK, but if I'm honest, 99.3 percent of those friends are those I met only once or acquaintances who live too far away to see regularly. That leaves 4 people, who I can call anytime, not feeling like I'm absolutely wasting their time. The remaining 0.2, I've decided, is my houseplant. I can tell it anything.

    Feeling the same way? You're absolutely not alone. Most of us find our "people" in school, but over time life changes: marriage, kids, etc. We grow out of our relationships and they grow out of us.

    So when the relationships come to an end, how do you find a new one?

    A woman in my apartment building, who I had seen around over the years, approached me one day and introduced herself. She bravely stated, "You seem cool. Do you want to hang out with me sometime? I'm looking for new friends." I almost dropped my bag of groceries at her social honesty. And now we get together for coffee a few times a year, gossip (八卦) about the neighbors, and take in the mail when one of us is on vacation. But a few times a year isn't enough for me.

    So, what counts as true friendship as you get older? For me, it's feeling comfortable enough to be myself. And if you're like me, it's also trust — not just keeping the secret, but trusting that my life choices aren't their gossip elsewhere.

    The world maps will soon be altered to reflect an eighth continent! Dubbed "Zealandia" the landmass that lies east of Australia covers 4.9 million km. Over 94 percent of it is submerged (淹没的) in the southwest Pacific Ocean, with just the islands of New Zealand and New C aledonia visible above sea level.

    To be clear, the underwater land is not a recent find. Researchers have known about its existence since 1995 when Bruce Luyendyk discovered and proposed an eighth continent that he called Zealandia. At the time, the area was dismissed as a collection of islands and land fragments (碎片), or at the most, classified as a micro continent—a landmass of continental crust that is not geologically connected to the nearest continent, in this case, Australia.

    However, after observing the areas features on an underwater topography map, New Zealand geologist Nick became convinced that Zealandia is a continent. Mortimer says that while Zealandia is much smaller than our seven continents, at over half the size of Australia, it is unfair to classify it as a microcontinent. The geologist argues, “If you could pull the plug on the world's oceans, then Zealandia would probably long ago have been recognized as a continent.”

    Geologist Christopher Scotese argues that too much of the landmass is underwater, asserting it's "almost a continent the way Pluto is almost a planet." Richard Ernst, a geologist, proposes coining a new term minicontinent—for Zealandia. He thinks this is perfect given that it is too large to be called a microcontinent and too small to be classified as a full-sized continent. Given that there is no international panel to decide the fate of Zealandia, its future as a continent is uncertain. Mortimer hopes that if supporters start using the term Zealandia, it may eventually catch on. Whether that happens remains to be seen, but for now, we will have to be satisfied with just seven continents!

Most of the 20th century has been a development on the Industrial Revolution taken to an extreme: people now own more products than ever before; there are enough unclear weapons to destroy the earth several times over; there is hardly any forest left and pollution has got to the point where we buy water. Within a few years I predict you will be able to buy air. (There once was a time when you didn't need to buy food or shelter either.)

Important developments in the last century are the breaking down of the class structures left over from the Industrial Revolution stage, bringing with it the empowerment of the "common man": the working day is set by law to only 8 hours a day; everyone has the vote; the media has less obvious government control; people have landed on the moon, sent spacecrafts to Mars and so on. Families have also shrunk drastically (强烈地); the nuclear family came about, and especially in the last half of the 20th century, one­parent families are becoming more common. This shrinking in the size of the family shows the increased independence of people — once upon a time people had to live in large groups to survive.

As humans have "become the gods", they have realized their individuality and independence and taken their control of the world to an extreme. In many countries the land is almost completely used in the production of food and as living space and they live in small cities which are entirely human constructed, made from materials which are also entirely human constructed (concrete bricks) with hardly any remains of nature. Weeds are poisoned because they are messy; even parks have trees grown in tidy lines; grass is mowed to keep it short and so on. I think the massive drug "problem" troubling people is a result of too much of this influence, humans needing to escape the stark world they have created by entering fantasy worlds.

Over the last 100 years, the 20th century consciousness has spread throughout the world; most of Asia has been thoroughly "Westernized", and most of the Third World is being overrun by Western ways of doing things and living.
