If you have a long holiday to spend, where can you go?

    Nikoi Island, Indonesia

    Less than 85 km-but somehow a whole world away-from Singapore's shining skyline lies Nikoi Island. Surrounded by white sandy shorelines and vivid coral reefs, Nikoi's centre is hidden in rainforest, resulting in amazing biodiversity seen in its native plants, animals and bird life. Marrying traditional Indonesian craftsmanship with contemporary design, Nikoi boasts just 15 stilted（建于支柱上的）beach houses, all with breathtaking sea views, guaranteeing privacy and total escape from the daily routine.

    Amanpulo, Philippines

    The only property on Pamalican Island, the luxurious Amanpulo resort offers extremely impressive accommodation, with only access to over five kilometres of clean coral sand beach. Designed to resemble local Bahay Kubo homes, Amanpulo's beachside, treetop and hillside villas all feature comfortable decks（木质平台）with hammocks（吊床）from which to enjoy the spectacular views of the greenish-blue sea below. Fill your schedule with Amanpulo's signature adventures (including diving, windsurfing and sailing), recharge in the award-winning spa or feast on locally caught seafood-the choice is yours.

    Song Saa, Cambodia

    Song Saa's incredible ocean views, and breathtaking sunsets are a very typical example of pure paradise. Its 24 villas—each with their own sea-view private plunge pool-are designed to reflect the natural beauty of Cambodia's coastline; built from recycled wood with straw roofs and driftwood furnishings, these presences are stylish proof of Song Saa's admirable commitment to sustainability and conservation. You can choose to do as much or as little as you want here. With rainforest tours, island safaris and reef snorkeling（徒手潜水）, it just offers some of the activities that show this spectacular destination.

Yawning（哈欠）sends out certain messages—either “Oh, this movie is boring" or "I probably need to get some sleep". But did you know that a yawn can also help your brain to cool down when it is so overheated?

    A new study, led by a research team of Princeton University, has indicated（表明）that yawning could be the brain's natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily.com.

    The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.

    When people yawn, their jaw is also stretched, which increases blood flow and may also help cool the brain.

    The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawn. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.

    However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.

    According to Gallup, this is the first report to show that yawning frequencies(频率) change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.

    Wolves travel shorter distances and move slower during snowfall events, according to new research by University of Alberta biologists. The effects were most pronounced at night, when wolves hunt, and behaviour returned to normal within a day. Wolf tracks across snow in northeastern Alberta.

    "Our findings suggest that there is something about actively falling snow that causes wolves to slow down," said Amanda Droghini, a former MSc student in the Department of Biological Science and lead author on the study. "We don't know the exact mechanism behind that. It's unlikely that they were staying still because they were feasting on a recent kill. Instead, active precipitation（降雪量）might affect wolves' hunting abilities. Like rain, snow clears the air column of scent molecules. So, maybe falling snow makes it harder for wolves to detect the smell of prey."

    Over the course of two winters, the researchers used remote cameras to disclose snowfall events and estimate snow depth. To study wolf movement, they collected telemetry（测距仪） data from 17 wolves to calculate travel speed and duration, as well as resting periods. It is the first study to examine how large flesh-eating animals respond to snowfall events.

    With the effects of climate change on precipitation in the north forest region uncertain, it is difficult to predict the implications for wolf populations. Studies such as these increase our understanding of how large mammals react to normal snowfall events, but the type and amount of winter precipitation will likely have an impact on animal behavior and the energetic cost of movement.

    "Winter is already challenging for many wildlife species because moving through snow requires more energy. Snow can also make it harder for animals to access food resources," said Droghini, who conducted the research under the supervision of Professor Stan Boutin, Alberta Biodiversity Conservation Chair.

    "Anything that increases those costs, such as increased rain-on-snow events, could lead to lacking in nutrition, poor body condition, and even starvation as animals are unable to make up for those additional costs. That is one of the worst-case scenarios（设想）but, in truth, we know very little about potential changes to precipitation patterns and how wildlife will respond to those changes."

    The values of artistic works, according to cultural relativism (相对主义), are simply reflections of local social and economic conditions. Such a view, however, fails to explain the ability of some works of art to excite the human mind across cultures and through centuries.

    History has witnessed the endless productions of Shakespearean plays in every major language of the world. It is never rare to find that Mozart packs Japanese concert halls, as Japanese painter Hiroshige does Paris galleries, Unique works of this kind are different from today's popular art, even if they began as works of popular art. They have set themselves apart in their timeless appeal and will probably be enjoyed for centuries into the future.

    In a 1757 essay, the philosopher David Hume argued that because "the general principles of taste are uniform (不变的) in human nature," the value of some works of art might be essentially permanent. He observed that Homer was still admired after two thousand years. Works of this type, he believed, spoke to deep and unvarying features of human nature and could continue to exist over centuries.

    Now researchers are applying scientific methods to the study of the universality of art. For example, evolutionary psychology is being used by literary scholars to explain the long-lasting themes and plot devices in fiction. The structures of musical pieces are now open to experimental analysis as never before. Research findings seem to indicate that the creation by a great artist is as permanent an achievement as the discovery by a great scientist.

    An earthquake is one of the most common natural disasters. It may cause great damage. So it is wise to learn some simple safety tips to protect yourself or your family members.

    Fragile items like those made of glass are easily broken and should usually be placed on a lower surface, near the ground instead of placing them in the cupboards higher up. Never place them near your bed, sofas and other furniture where you would be sitting or lying down. When there is a strong movement, these pieces will fall on the floor directly and not on you.

    There is a strong chance of short circuits (短路) and fire during an earthquake. Make sure you turn off electrical connections and gas immediately when an earthquake happens.

    During an earthquake, lie beneath an object that is not easily damaged. Do not go near objects that could directly fall on you. Never use the elevator to go down. Stay inside until the shaking stops and it is safe to go outside. Research has shown that most injuries happen when people inside buildings try to go out. Use the staircases at all times.

    If you are outdoors, do not take shelter under a tree, streetlights, electric poles or tall buildings. If you are driving, stop your car and stay in a safe place. Do not park your car under a tree or any tall object.

    If trapped in debris (瓦砾堆), cover your mouth with a handkerchief or clothing. Tap on a pipe or the wall so that rescuers (营救人员) can find you. Use a whistle (哨子) if one is available. Never shout for help. Shouting can cause you to breathe in dangerous amounts of dust. Do not light a match because you may burn yourself. Do not move about or kick up dust.

Most people assume that the human brain is set on "automatic"—that means it learns all by itself. But this isn't always true. We need to train ourselves to be better learners—to actively take part in the learning process and to reflect on what we have learnt. These kinds of learning behaviours are called "active learning". I suggest doing four things to take an active role in your learning.

Listen to the outer voice

There are two kinds of voices: the inner voice and the outer voice. Your inner voice expresses your personal opinions, while the outer voice tells you about opinions from what you hear or read. Although your inner voice can be useful, it can also get in the way of learning. If you keep paying too much attention to it, you risk missing important information. Instead, active learners are open-minded and focus on what the speaker/ write is saying, not on what their brain is saying in the background. In this way, they are in a better position to make decisions.

Ask questions

Asking questions is the easiest way to promote active learning. When you get information from someone, from books or the Internet, ask two, three, even five question about the topic. The answers will lead you to further learning, and the very act of working out questions will help you to achieve a higher level of understanding about the topic. In short: Do not stop being curious.

Get to the truth

Active learners do not accept everything they learn. They attempt to find the truth at the heart of each idea. Even when an idea sounds entirely unlikely, there may be an aspect of it that is based on truth. So if someone says that dinosaurs still exist today, think about why they believe this. Where does the idea come from? Do they have enough data to support their views? If you try to find out the source of an idea, no matter how crazy it seems, you will increase your chance of learning something.

Focus on the message

Many people miss out on learning opportunities because they let their feelings get in the way. They refuse to learn or ignore what is said because of who the speaker/ writer is. It is true that we cannot help disliking some people —this is human nature, after all. But do not forget you can still learn from them. Active learners do not judge people based on firs impressions or personal feelings. Instead, they separate the message from the message. This goes the other way as well—do not just assume that some people are always right because of who they are or just because they are your friends.
