1 . Is It Worth Buying Organic Food?
Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.
The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

3 . On January 15th, the Guardian showed off its new, smaller look, shifting from its distinctive “Berliner” format to a tabloid(娱乐小报) shape with a redesigned logo in black type. But the more dramatic makeover is of the financial books of Guardian Media Group (GMG), publisher of the Sunday Observer and the daily Guardian, which may find its new operation in the black next financial year. A newspaper business that two years ago was threatened with existentially worrying losses appears on the edge of breaking even.
The turnaround is partly due to steep cost-cutting, which is a dog-bites-man story in journalism. But the Guardian would manage the achievement while still giving away news free online, and that is a story worth telling.
In January 2016 David Pemsel, the new chief executive of GMG, and Katharine Viner, the new editor-in-chief of the Guardian, informed staff that GMG’s endowment fund, meant to ensure the financial security of the paper in the long run, had lost £100m ($140m) in just half a year, taking it to £740m. Mr Pemsel was advised by industry peers to cut costs and put online news behind a paywall. He and Ms Viner cut costs by 20%, or more than £50m. Alan Rusbridger, Ms Viner’s predecessor(前任), had led the newspaper to global relevance with a large online readership. But he spent without thinking of the consequences. In two years GMG has reduced its employees by 400, to about 1,500.
Yet unlike a growing number of newspapers, the Guardian has not put up a paywall. Instead it has pursued a membership model, asking online readers to contribute whatever they like. About 600,000 now do, with annual payments or one-off amounts. American readers tend to choose the latter option, Ms Viner says. GMG says the total figure amounts to tens of millions of pounds per year. Ms Viner says revenue from readers (including 200,000 print subscribers) is now greater than revenue from advertisers.
The result is steadily declining operating losses: from £69m two years ago to £45m last financial year and, Mr Pemsel says, less than £25m in the year that ends on April 1st. He predicts breaking even next year. Giving up its own printing presses and going tabloid will help, saving several million pounds a year. The Guardian may now physically look more like its peers, but its turnaround story remains distinctive.

6 . Top Exhibitions to See in London in 2023
Architectural: Vanishing Points
While we like to think of architecture existing purely in the real world, emerging designers and architects are using platforms like Instagram to create structures in the virtual world. This collection of works, which range from the practical to the fantastical, are all by architects who have gathered significant social media followings.
In the Digital Universe at ROCA London. 8 February—31 July, free.
Flowery: Orchids
This annual festival is back in bloom (开花), this time inspired by the beauty and biodiversity of Cameroon. Just like previous years, the orchids are spread throughout the various zones of the Princess of Wales conservatory and accompanied by sculptures that are just as colourful as the flowers on display.
At Kew Gardens. 4 February —5 March, &16.50—entrance to the gardens included.
Female Abstraction: Action, Gesture, Paint
Art history has often shone a light on the men of Abstract Expressionism, such as Jackson Pollock and Mark Rothko. Well, now’s the time to let the most important women of the movement take the limelight in an exhibition that includes works by American artists such as Lee Krasner and Helen Frankenthaler, but spreads the net wider to include the female abstract artists from Europe, Asia and the wider world, with whom most of us will be unfamiliar.
At Whitechapel Gallery. 9 February—7 May, £ 16.50—concessions available.
Powerful Portraits (肖像): Alice Neel
The largest UK exhibition to date of American painter Alice Neel’s work will bring together her figurative pieces from across her 60-year career. Neel went against the popular grain by painting figures when abstract works were most popular, and she painted subjects that other artists ignored — pregnant women, labour leaders, black children, civil rights activists and strange performers. It’s high time we had a major show of her work in London, and the Barbican has duly provided.

7 . Increasingly, over the past few decades, people, especially young people, have become aware of the need to change their eating habits, because much of the food they eat, particularly processed food, is not good for health. Consequently, there has been a growing interest in natural foods. Foods which do not contain chemical additives and which have not been affected by chemical fertilizers, are widely used in farming today.
Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic-matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use ofchemicals and fertilizers, the main purpose of which is to increase the amount — but not the quality — of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and movefreely in healthy pastures (牧场). Compare this with what happens in the massproduction of poultry (家禽): there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food, they also lay eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar. This is actually a non-essential food! Although a natural alternative, such as honey, can be used to sweeten food if it is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be addictive: the quantity we use has grown steadily over the last two centuries and in Britain today each personconsumes an average of 200 pounds a year! Yet all it does is to provide us with energy, in the form of calories. There are no vitamins in it, no minerals and no fiber.
It is significant that nowadays fiber is considered to be an important part of a healthy diet. In white bread, for example, the fiber has been removed. But it is present in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence the emphasis is placed on the eating of whole meal bread and more vegetables by modern experts on “healthyeating.”

9 . Can artificial intelligence uncover a liar? It sounds like science fiction, but such an AI system is possible. The question is: How accurate can it be? Rada Mihalcea, a professor of computer science and engineering at the University of Michigan, has worked on deception detection for about a decade. This is how they constructed one AI deception detector, and how it works.
The first thing that researchers working on artificial intelligence and machine learning need is data. In the case of the work that Mlhalcea did, they began with videos from actual court cases. For example, a defendant speaking in a trial in which they were found guilty could provide an example of deceit; they also used testimony from witnesses as either example of truthful or deceitful statements. Altogether, they used 121 video clips and the corresponding transcripts of what they said—about half represented deceptive statements, and half truthful. It was this data that they used to build machine learning classifiers that ultimately had between a 60 to 75 percent accuracy rate.
One thing the system noticed is the use of pronouns—people who are lying would tend to less often use the word ‘I’ or ‘we’, Mihalcea explains. “Instead, people who are lying would more often use ‘you,’ ‘yours,’ ‘he,’ ‘they,’ and ‘she.’” That’s not the only linguistic signal: someone telling a lie would use “stronger words” that “reflect certainty,” she says. Examples of those types of words are “absolutely,” and “very,” while interestingly, people telling the truth were more likely to use words such as “maybe” or “probably.” “I think people who are deceptive would try to make up for the lie they are putting forward,” she says, “and so they try to seem more certain of themselves.” As for gestures, she points out that someone being deceitful would more likely look directly into the eyes of the person questioning them. They also tended to use both hands when gesturing. Instead of just one—also, she suspects, as part of trying to be convincing.
However, Mlhalcea’s work is “far from perfection,” she concedes. “As a researcher, we are excited we were able to get to 75 percent accuracy.” But looked at another way, that’s an error rate of one in four. Ultimately, she sees technology like this as being assistive for people—it could, for example, indicate that it noticed something “unusual” in a speaker’s statement, and then perhaps have a person “investigate more.”
1. What researchers need first to predict whether a defendant is lying is ______.A.statements | B.data | C.pronouns | D.gestures |
