Conflict is on the menu tonight at the café La Chope. This evening, as on every Thursday night, psychologist Maud Lehanne is leading two of France's favorite pastimes, coffee drinking and the “talking cure”. Here they are learning to get in touch with their true feelings. It isn't always easy. They customers - some thirty Parisians who pay just under $2 (plus drinks) per session - care quick to intellectualize (高谈阔论)，slow to open up and connect. “You are forbidden to say ‘one feels,' or ‘people think',” Lehane told them. “Say ‘I think,' ‘Think me'.”

A café society where no intellectualizing is allowed? It couldn't seem more un-French. But Lehanne's psychology café is about more than knowing oneself: It's trying to help the city's troubled neighborhood cafes. Over the years, Parisian cafes have fallen victim to changes in the French lifestyle - longer working hours, a fast food boom and a younger generation's desire to spend more time at home. Dozens of new theme cafes appear to change the situation. Cafes focused around psychology, history, and engineering are catching on, filling tables well into the evening.

The city's psychology cafes, which offer great comfort, are among the most popular places. Middle-aged homemakers, retirees, and the unemployed come to such cafes to talk about love, anger, and dreams with a psychologist. And they come to Lehanne's group just to learn to say what they feel. “There's a strong need in Paris for communication,” says Maurice Frisch, a cafe La Chope regular who works as a religious instructor in a nearby church. “People have few real friends. And they need to open up.” Lehanne says she'd like to see psychology cafes all over France. “If people had normal lives, these cafes wouldn't exist”, she says, “If life weren't a battle, people wouldn't need a special place just to speak.” But them, it wouldn't be France.

    Plastic is easy, convenient, cheap and long-lasting, but it does great harm to the environment.

    Since plastic entered mass production, 8 billion tons have been produced – and we aren't very good at recycling. By 2015, 6,945 tons of plastic waste had formed, with around 9 percent of it getting recycled. About 79 percent of it ends up in landfills or around the environment, including the ocean. We may end up drowning in plastic before long.

    Chemists at Colorado State University have found a polymer（聚酯）that has many of the qualities of plastics – it's light, strong, durable and heat-resistant – but that can be changed back to its original small-molecule（分子）state for complete recycling. Even after being recycled, the polymer can be turned back into its plastic-like state, and this can be done quickly and cheaply.

    This new polymer has all the good qualities of plastics, yet it is relatively easy to make and to recycle. Making it requires room temperature conditions, a short reaction time to bond the monomer（单体）into polymers and only a small amount of the catalyst（催化剂）remains in the end product. It has a high molecular weight, stands up to heat and generally behaves like plastic. Recycling it requires similarly little effort. Mild lab conditions are required and so is a catalyst. Once applied, the polymers are once again monomers in a matter of minutes and can be used to create another product.

    But don't get too excited about this just yet. Scientists stressed that the polymer isn't ready for mass products just yet. There's still plenty of development to do, including making it more economical to produce and recycle.

    About aspirin:

    Aspirin is a commonly used drug which can be taken to relieve discomfort caused by numerous medical problems including headaches, toothache, inflammation and infections. It is also suitable to treat colds and flu-like symptoms, and to reduce a high temperature.

    Who can take aspirin?

    Adults and children over 16 years of age.

    Who should not take aspirin?

    Women who are pregnant, or plan to become pregnant. Aspirin may harm your unborn baby.

    Women who are breast-feeding. Aspirin can pass into your breast milk and may harm your baby.

    People who have any problems with the way the liver works or with the way the kidneys work.

How to take aspirin:

    Take aspirin after meals, with a full glass of water or milk.

    The recommended dose (剂量) ranges from two to three tablets at a time. Never take more than 4g 12 tablets) in any 24 -hour period.

    You must not take these tablets with any other medicine which contains any aspirin or painkiller.

    How to store aspirin:

    Keep all medicines out of the reach and sight of children.

    Store aspirin in a cool, dry place, away from direct heat and light.

    Do not put aspirin in the bathroom because the dampness there can cause it to lose its effectiveness.

    Throw away aspirin that smells strongly of vinegar.

    Possible side effects:

    Feeling sick, increased risk of bleeding, stomach pain, indigestion and heartburn are common. If these effects continue, contact your doctor.

    Ringing in the ears, difficulty breathing, dizziness, and mental confusion are rare. If these occur, stop taking the drug and contact your doctor for further advice.

    Modern lifestyles are generally quite different from those of our hunter-gatherer ancestors, a fact that some claim as the cause of the current rise in global obesity, but new results published July 25 in the open access journal PLOS ONE find that there is no difference between the energy expenditure(耗费) of modern hunter-gatherers and Westerners, casting doubt on this theory.

    The research team behind the study, led by Herman Pontzer of Hunter College in New York City, along with David Raichlen of the University of Arizona and Brian M. Wood of Stanford measured daily energy expenditure among the Hadza, a population of traditional hunter-gatherers living in the open Savannah of northern Tanzania. Despite spending their days hiking long distances to seek for wild plants and game, the Hadza burned no more calories each day than adults in the U.S. and Europe. The team ran several analyses accounting for the effects of body weight, body fat percentage, age, and gender. In all analyses, daily energy expenditure among the Hadza hunter-gatherers was indistinguishable(难以区分的) from that of Westerners. The study was the first to measure energy expenditure in hunter-gatherers directly; previous studies had relied entirely on estimates.

    These findings overturn the long-held assumption that our hunter-gatherer ancestors expended more energy than modern populations, and challenge the view that obesity in Western populations results from decreased energy expenditure. Instead, the similarity in daily energy expenditure across a broad range of lifestyles suggests that habitual metabolic(新陈代谢的) rates are relatively constant among human populations. This in turn supports the view that the current rise in obesity is due to increased food consumption, not decreased energy expenditure. It means we have more to learn about human physiology(生理学) and health, particularly in non-Western settings.

    "These results highlight the complexity of energy expenditure. It's not simply a function of physical activity," says Pontzer.” Our metabolic rates may be more a reflection of our shared evolutionary past than our diverse modern lifestyles."

    A recent experiment proves that bees can save time and energy when they fly around to different flowers.

    Dr Nigel Raine, from the Royal Holloway University of London, has always been interested in finding out why animal behave like they do. He is also interested in bees. It was not a surprise when he and some other scientists from Queen Mary University of London discovered that bees can quickly solve a problem that takes computers many days.

    Flowers make pollen (花粉), and when bees visit them, they carry the pollen to other flowers. The plants need the pollen to make seeds that will grow. Dr Raine notes that we get a lot of our food from plants, so it is important to know how the bees move around and take the pollen between flowers. The scientists wanted to examine the journey that the bees take and how they save energy when they do this. They completed the experiment on the roof of Queen Mary University, using artificial flowers and a large amount of nectar, a sweet liquid produced by flowers. They taught one bee to visit all the flowers in one place at the same time. When the bee got to know the location of the flowers well, they saw how it flew around and returned home with the nectar. After this, they changed the locations of the flowers. The scientists thought the bee would follow the route it knew already. This would mean that it followed a longer route than it needed to, and so it would use more energy. They watched the bee carefully as it travelled between the flowers in their new location, and they made notes. But in the experiment, the bee changed its route and flew a shorter distance.

    The problem that the bee solved is similar to a maths puzzle called the 'travelling salesman problem'. A salesman who goes to different places to sell things wants to travel the shortest distance. But he has to calculate the length of many possible routes to know which one is the shortest. A computer can calculate this but the experiment shows bees can do the same calculation quickly with a tiny brain. Scientists are very interested in how they do this. It would help us to understand how pollen is moved around. In addition, if they find this out, it could help us to improve communication networks. This might help humans to reduce traffic jams when there is an accident, for example.
