“A photograph that one has taken of oneself, typically with asmart phone or webcam and uploaded to a social media website” is the definitionof “selfie” in the Oxford English Dictionary. In fact, it wasn't even in thedictionary until August of last year. It earned its place there because peopleare now so obsessed with (对……痴迷) selfies ─ wetake them when we try on a new hat, play with our pets or when we meet a friendwhom we haven't seen in a while.

But is there any scientific explanation for this obsession?Well, you should probably ask James Kilner, a neuroscientist(神经系统科学家) atUniversity College London.

Through our lifetime we become experts at recognizing andinterpreting other people's faces and facial expressions. In contrast,according to Kilner, we have a very poor understanding of our own faces sincewe have little experience of looking at them ─ we just feel them most of thetime.

This has been proved in previous studies, according to the BBC.

Kilner found that most people chose the more attractive picture.This suggests that we tend to think of ourselves as better-looking than weactually are. To further test how we actually perceive our own faces,Kilner carried out another study. He showed people different versions of theirown portrait ─ the original, one that had been edited to look less attractiveand one that was made more attractive ─ and asked them to pick the versionwhich they thought looked most like them. They chose the more attractiveversion.

But what does it say about selfies? Well, isn't that obvious?Selfies give us the power to create a photograph ─ by taking it from variousangles, with different poses, using filters (滤色镜) and so on ─that better matches our expectations with our actual faces.

“You suddenly have control in a way that you don't have innon-virtual(非虚拟的)interactions," Kilner told the Canada-based CTV News. Selfies allow you“to keep taking pictures until you manage to take one you're happy with”, heexplained.

    Blue Planet II's latest episode focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.

    Though it seems now that the world couldn't possibly function without plastics, consumer plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.

    We put all these plastics into the environment and we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.

    And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don't have to remake our planet energy system.

This is not a problem where we don't know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose (处理) of it. We know how to recycle. We can all start by thinking twice before we use single—use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag—when taken collectively, these choices really do make a difference.

    Heat has been used to control hair for hundreds of years. But how much is too much? If you have ever opened a very hot oven, you know that heat can burn your eyebrows off your face very quickly. A scientist from Purdue University in Indiana is trying to find a scientific answer on how hot is too hot when it comes to your hair.

    Many women and some men are very particular about their hair. Some people who have naturally curly hair prefer to have it straightened. Others with straight hair want to have curls. Tahira Reid is one of those people. As an African-American woman, she is familiar with the challenges of maintaining (保养)curly hair.

    Tahira Reid and other researchers at Purdue University are studying how heat treatment interacts with different types of hair and how to prevent damage. Amy Marconnet is an assistant professor. She says the team is seeing how heat and temperature relate to their research.

    In a Purdue University's lab, team members designed a hair straightener tool —a flat iron with temperature control. They attached it to a robotic arm that moved over pieces of hair. They controlled the temperature while the device straightened hair.

    What did they find? Their study found that the heat weakens or breaks a protein called keratin, responsible for the hair's shape, and temporarily changes it. But nobody knows exactly what level can make the heat actually cause forever change. Researchers say early results are a bit inconclusive.

    It turns out that everyone's hair is different and there's no exact temperature where hair straightening becomes hair damage. Ms Reid says they will continue their research in the hope of finding what works best without damaging hair.

    Photos of eight-year-old Wang Fuman, nicknamed by “Snowflake Boy” in Yun Nan, shared by his principal on Tuesday, showed the boy has a red face from the low temperatures and apparently did not wear enough clothes to keep warm. He also suffered from frostbite. He stood alone with his white hair and eyebrows while other classmates behind were clearly amused and laughing. The picture drew widespread attention around the whole world. Many netizens (网民) were sympathetic to the boy's difficulties, with many Mircoblog users giving comments under the report.

    Just after the report, a donation of 100,000 yuan was sent to his Primary School. Constantly, help still pours in for the Chinese boy. But the local authorities call on others to pay attention to other similar rural areas and give them timely aid. In China, there are still so many children just like Fuman living by himself with parents migrating to cities to make a living.

Everything to know about Singapore

Here is how to plan the best possible trip to this impressive city-state.

When to go

Positioned just one degree north of the Equator, Singapore is consistently tropical. So it's more a matter of when not to go. Namely: the monsoon season between November and January when the city is blanketed in regular rainfall.

What to celebrate

Singapore celebrates its independence in an annual celebration known as National Day. Every year on August 9, the holiday is marked with great excitement that extends into the evening, ending in a massive fireworks display over Marina Bay.

What to eat

Hainanese chicken rice is considered the national dish of Singapore, as you can find it just about everywhere. If you are looking for something a bit spicier, try laksa--a coconut curry-based noodle soup.

Souvenir to take home

The Merlion is Singapore's official mascot(吉祥物), a mythical beast with the head of a lion and the body of a fish. Many local salesmen offer hand-carved figurines that fit easily into carry-on luggage and will serve as a lasting symbol of your time here. Anyone who's ever visited this place directly connects the symbol to the city.

Travel trip

Hawker centers are open-air food markets featuring delightful street food. Eat at these as much as possible to support local business and for a true taste of Singaporean dining customs. While each has its own charm, Maxwell Road Hawker Center in Chinatown is the most famous.

Instagram-worthy view

A photo from the world's largest rooftop infinity pool-- connecting the three towers of the Marina Bay Sands-- is a must for many tourists here. But back on the ground, Merlion Park affords a more impressive view of the hotel itself.
