    Pound for pound, healthy food is cheaper than junk food, according to a new research from the U. K.

    The Institute of Economic Affairs found that the average cost for a “wide range” of healthy foods was about £ 2 per kilogram, compared with £ 3 a kilogram for less-healthy products such as processed and ready-made foods.

Still, study after study finds that cost is often a barrier when it comes to healthy eating. Convenience drives consumers to care about habits more than prices, the U. K. study concluded. Taste and convenience often play a larger role in people's food choices than price or nutritional quality.

    “Processed foods are extremely expensive, especially when it comes to the nutrient value. Some of the healthiest, most inexpensive foods aren't so attractive. Beans cost next to nothing, especially when bought dry and in great amounts. They take time and some skills to prepare. ” said Ciara Foy, a nutritionist.

    Instead, busy parents reach for the chicken. “You might be getting something that has enough calories to fill you up but you're actually not getting any nutrients, so your body's going to keep wanting more and more food,” said Foy. “And that's why in North America we, re overfed and undernourished (营养不良的).”

    Makers tend to try to promote their product based on perceived health benefits, which makes consumers confused at times with what is a healthy product and how much you should pay for those benefits. The most expensive items, healthy or not, are the ones that end up in the trash. “A lot of people waste a lot of food,” Foy said. It's estimated that more than $ 30 billion of food is wasted in Canada every year. Foy recommends taking a look in your fridge to see what needs to be used up when planning for the next night's meals. “If you actually cut down on the waste you'll find that you can afford healthy food,” Foy said.

    One of the most efficient ways to achieve peace and speed up economies (经济) is to provide girls with better education and more rights. Today, girls' lack of access (进入) to basic education is getting more serious when it comes to the use of digital (数码的) technology, leaving them far behind boys. And because the world is even more digital, those who lack basic internet skills will find it increasingly more difficult to take part in the formal economy, to get a quality education, and to have their voices heard.

    Since 2013 the global gender gap (性别差异) in male and female access to the Internet has actually increased from 11 to 12 percent. Worse yet, women and girls living in the poorest countries are 31 percent less likely than men and boys to have access to the Internet. In developing countries, some 200 million fewer women than men own a mobile phone, the most common means of internet access there. This digital divide is increasing, and should it continue at the present pace, it is projected that over 75 percent of women and girls will lack internet access and digital skills.

    There are many causes of the digital gender gap. They include girls' exclusion (排斥) from basic education, from specific technology education and high costs of mobile phones and internet access.

    Indeed, one of the so-called reasons why girls may be discouraged from learning how to access and use digital technology is also a groundless one: that girls are simply not good at using technology.

    Without the help of the government, most of the benefits of technological change will be enjoyed only by men, exacerbating gender inequality.

    American college students are becoming more adventuresome as they study abroad, showing less interests in English-speaking destinations such as Great Britain and Australia and more in such countries as China, India, Argentina and Brazil.

    Britain remained the most popular study destination in 2005, according to annual figures from the Institute of International Education, followed by Italy, Spain and France. But the number of American students studying in Britain and Australia descended a little, even as the number of American students abroad rose by 8%. The growth came in non-English speaking European countries and in Asia. China is now the eighth most popular destination for American students, attracting nearly 6,400 in 2005, up 35% from the number of the year before. Argentina and India saw increases of more than 50%.

    Allan Goodman, president of the Institute of International Education, said that a range of factors contributed to the trend, from growing awareness of globalization after the terrorist attacks on September 11, 2001, to programs such as former President Bush's National Security Language Initiative, which trains soldiers, intelligence officers and diplomats in foreign languages. “What Americans are doing is waking up and discovering there's a world out there,” he said.

    Other figures showed the flow of students in the opposite direction, from foreign countries into American universities. The institute found that international enrollment (入学) in American higher education remained steady at about 565,000. The figures are of keen interest to universities, which depend on foreign students for teaching and research help, and to policy-makers, who consider it important, as future foreign leaders may be familiar with the United States. The year of 2005 saw big increases in students from South Korea, Mexico and Taiwan of China. India sends the most students and China is No.2. Other countries that show large percentage increases in the number of students sent to the US include Nepal and Vietnam, while Japan, Turkey and Malaysia saw declines. About 58% of international students in the US come from Asia.

    Anyone can try to lead a group, but not every individual is cut out for leadership. The better leaders possess a few qualities that can mean the difference between the success and failure of the group. These are the qualities the leader of higher rank will look for when choosing a leader for a group, or when evaluating the performance of a leader. They're also the qualities team members want in a group leader, and appreciate when they find them.

    Take Responsibility

    Group leaders might share tasks around a group as necessary, but eventually a group leader needs to be able to accept that responsibility lies on his shoulders. That means that if things go wrong in a group project, he's the one who must accept the consequences and work out what mistakes are made. The group leader won't always have the power to control everything group members do, but he should be ready to admit any mistakes the group has made as a result of his leadership

    Concern for Members

    The group leader has a commitment to the task or project at hand, but perhaps more importantly, he has a real concern for each and every person who is part of his group. This means getting to know the strengths, weaknesses and goals of team members, as well as making time to build the group through collective activities. The group leader should make sure that everyone is included, even if an individual is new to a group.

    Good Listener

    The group leader needs to be able to listen to the suggestions, complaints and ideas of group members. Not only will this allow complaints to be addressed and potentially suitable ideas to be put into practice, but a leader who listens will also encourage group members to share their concerns and thoughts, creating an atmosphere of free speech and productivity.

    We have heard some interesting ways that 5G wireless technology might change our lives in the future.

    5G, short for the 5th generation mobile communication technology, promises Internet speeds between 50 to 100 times faster than current 4G systems. While 5G is set to be used in some limited areas of America this year, much of the world is not expected to receive widely available service until 2023.

    One project in Britain, however, is already testing this superfast technology on an unlikely group of Internet users-cows. The project was developed by American technology company Cisco Systems. It also receives money from the British government. Cisco says the program seeks to explore the future of 5G connectivity in rural areas around the world.

    Testing areas were set up at farms in three rural areas of England. The cows are equipped with 5G-connected devices (装置) that link up to a robotic milking system, which uses sensors and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each individual cow. It then positions equipment to the right body position for milking. During the process, machines release food for the cow as a reward.

    Other 5G technology tools include automated brushes that turn on when the cow rubs up against them. Sensors also control the amount of light to the cows' living areas depending on the weather. And, an automatic feeding system makes sure the animals always get enough to eat.

    Duncan Forbes, head of the project, told Reuters that the project shows the farm's cow operations can be greatly improved with 5G technology and that the experiment provides strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in rural communities across the world.

    City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air thah forest trees.

    As we all know, the earth would be freezing or burning hot without CO2. However, CO2 is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.

    Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2 at the same rate as forest trees do. So some researchers decided to find out.

    To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.

    City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.
