Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality. Researchers at the University of New South Wales, Australia, have invented a soft skin stretch device (SSD), a haptic (触觉的) device that can recreate the sense of touch. Haptic technology mimics (模仿) the experience of touch by stimulating small areas of the skin in ways that are similar to what is felt in the real world, through force, vibration (震动) or motion. Vibration is the most common haptic technology today and has been built into many electronic devices, such as one attached to the back of a trackpad (触控板) in laptops, which mimics a button clicking. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely, according to Mai Thanh Thai, lead author of the study. The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through soft, artificial "muscles". "Our three-way directional skin stretch device, built into the fingertips of the wearable haptic glove we also created, is like wearing a second skin — it's soft, stretchable and mimics the sense of touch — and will enable new forms of haptic communication to enhance everyday activities, " said Thanh Nho Do, senior author of the study. It works like this: Imagine you are at home and you call your friend who is in Australia. You wear a haptic glove with the SSDs and your friend also wears a glove with integrated (集成的) 3D force sensors. If your friend picks up an object, it will physically press against your friend's fingers. And his/her glove with 3D force sensors will measure these interactions. The force signals can be sent to your glove so your device will generate the same 3D forces, making you experience the same sense of touch as your friend. The haptic devices could be applied in various scenarios, allowing users to feel objects inside a virtual world or at a distance. This could be especially beneficial during such times like the COVID-19 pandemic when people rely on video calls to stay connected with loved ones. Or it could be used in medical practices. Doctors can feel a patient's organ tissues with surgical tools without touching them.

阅读理解When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making. After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine. The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge. He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water. Over the years, John has taken on many big jobs. He developed a greenhouse-like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China. "Ecological design" is the name John gives to what he does. "Life on Earth is kind of a box of spare parts for the inventor," he says. "You put organisms in new relationships and observe what's happening. Then you let these new systems develop their own ways to self-repair."

阅读理解Rachel Hore's fascinating novels move between the past and the present. Her latest The House on Bellevue Gardens is set in London now and in the early 1960s. Best-selling author Rachel Hore's previous novels include The Glass Painter's Daughter, which was shortlisted(入围) for the 2010 Romantic Novel of the Year award, and A Gathering Storm, which was shortlisted for the 2012 Historical Novel of the Year award. Here, she shares three books that made an impact on her life. Orlando by Virginia Woolf Reading Orlando for the first time in my late teens gave me a wonderful sense of freedom and the possibilities that a life full of books can offer. Forever youngOrlando possesses "the strength of a man and a woman's grace". He lives through four centuries and has many disguises; sometimes he even changes his gender. It was an excellent literary work through history that excited and inspired me. Flight Behaviour by Barbara Kingsolver I've read many of Barbara Kingsolver's novels, including her well-known The Poisonwood Bible, admiring how easily she writes about the power and beauty of the natural world, of which humanity is a dependent part. I particularly love Flight Behaviour because she engages the reader easily with an ambitious subject for fiction — climate change. Her story makes us all care about what we are doing to our world. The Hawk in the Rain by Ted Hughes We were given The Thought Fox to read at school and I was so deeply impressed with its central image of the fox in the snow inspiring the poem that I spent that week's money on the book it appears in. I read and re-read it and was amazed! I loved the writer's technique of description, as well as the energy, the violence and the sensuousness (敏感) of those poems. Everyone should have their ‘discovery of poetry' moment, and mine was Ted Hughes.

阅读理解Improvements to energy efficiency, such as LED lights, are seen by many authorities as a top priority for cutting carbon emissions. Yet a growing body of research suggests that a rebound effect could wipe out more than half of the savings from energy efficiency improvements, making the goals of the Paris Agreement on climate change even harder to hit. A team led by Paul Brockway at the University of Leeds, UK, looked at the existing 33 studies on the impact of the rebound effect. First comes the direct rebound: for instance, when someone buys a more efficient car, they may take advantage of that by driving it further. Then comes the indirect rebound: fuel savings leave the owner with more money to spend elsewhere in the economy, consuming energy. Although the 33 studies used different methods to model the rebound effect, they produced very consistent estimates of its impact, leading the team to conclude that the effect wipes out, on average, 63 percent of the anticipated energy savings. "We're not saying energy efficiency doesn't work. What we're saying is rebound needs to be taken more seriously," says Brockway. The idea that increased efficiency may not deliver the hoped-for savings dates back to the Jevons paradox(悖论), named after the economist William Stanley Jevons, who, in 1865, observed that more efficient coal use led to more demand for coal. If the rebound effect does prove to be as big as suggested, it means future global energy demand will be higher than expected and the world will need far more wind and solar power and carbon-capture technology than is currently being planned for. But that doesn't mean nothing can be done to limit the rebound effect. One answer is to double down on energy efficiency and do twice as much to achieve the same effect.
