【推荐1】If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.

The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic       was eyesight.In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has better benefits. It is connected to better health.

It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it's worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.

Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Slovis explained this. Glasses soften their appearance, he said. Sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren't found guilty.

Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip（时髦的）.

【推荐2】In recent years there has been a steady attack on salt from the doctors; salt is bad for you-regardless of your health. Politicians also got aboard."There is a direct relationship" US Congressman Neal Smith said "between the amount of sodium (钠) a person consumes and heart disease circulatory（循环的)disorders stroke and even early death."

Frightening if true! But many doctors and medical researches are now beginning to feel the salt scare has gone too far."All these remarks and cry about salt is unnecessary" Dr. Dustan. insists. "For most of us it probably does not make much difference how much salt we eat." Dustan's most recent short-term study of 150 people showed that those with normal blood pressure experienced no change at all when placed on an extremely low-salt diet or later when salt was reintroduced. Of the hypertensive (高血压的) patients however half of those on the low-salt diet did experience a drop in blood pressure which returned to previous level when salt was reintroduced.

"An adequate to somewhat excessive (过度的)salt intake has probably saved many more lives than it has cost in the general population" said Dr. John H Laragh. "So an opinion that the whole population should avoid salt makes no sense."

Medical experts agree that everyone should practice reasonable “moderation” （节制)in salt consumption. For the average person a moderate amount might run from four to ten grams a day or roughly 1/ 2 to 1/3 teaspoons. One to two grams of salt would come from the natural sodium in food. The rest would be added in processing preparation or at the table.

"Na is not your enemy "says Comek’s Dr.Laragh. "Salt is the No.1 natural component of all human tissue and the idea that you do not need it is wrong. Unless your doctor has proven that you have a salt-related health problem，,there is no reason to give it up. "

【推荐3】Dog owners swear that their furry best mend is in tune with their emotions, Now it seems this sense of interspecies connection is real: dogs can smell your emotions, and adopt them as their own

We already know dogs can see and hear the signs of human emotions says Biagio D'Aniello at the University of Naples Federico II, Italy. But nobody had studied whether dogs could pick up on olfactory(嗅觉的) signals from humans.

“The role of the olfactory system has been largely undervalued, maybe because our own species is more focused on the visual system.” says D'Aniello. However, dogs 'sense of smelling is far superior to ours, D'Aniello and his colleagues tested whether dogs could really sniff out our emotions. First, human volunteers watched videos designed to induce fear, happiness or a neutral response and the team collected samples of their sweat. Next, the researchers presented these sweat samples to dogs ,and monitored their behavior and heart rates. Dogs exposed to fear smells showed more signs of stress than those sniffing happy or neutral smells. They also had higher heart rates, and made less social contact with strangers.

D'Aniello's study suggests humans can unconsciously, hijack their dogs' emotion by releasing smells .A second study suggests dogs can return the favour, using their expressive faces.

Juliane Kaminski at the University of Portsmouth, UK, and her colleagues have found that dogs' faces fare most expressive when they know people are looking at them.

The researchers introduced dogs to a human who was either looking at them or facing away and either offering food or nothing. The team analyzed how much the dogs' facial movements varied in the four situations. They found that the dogs' facial expressions varied most when the person was looking at them. Kaminski says there was no sign of a “dinner table effect”, which “would predict that dogs try and look super-cute when they want something from the humans”.

It's not clear precisely how dogs visually signal us and how we respond, says Monique Udell of Oregon State University in Corvallis. “This kind of research is needed to fully understand the nature of the human-dog relationship.”

1. How did D'Aniello's research team carry out their study on dog's ability of sniffing out humans' emotions?
