That may be about to change. Engineer Xinge Yu of the City University of Hong Kong and his colleagues have developed a lightweight, flexible and wireless smell interface that can precisely deliver smells such as pineapple or green tea to VR users and more fully immerse them in scented virtual worlds. Previous smell interfaces have typically used bottles of liquid perfume, an atomizer (a device that turns liquids into a fine mist) and some method of blowing the atomized droplets out. This works, but it is rigid and has limited operating time between refills, and it does not easily allow for controlling intensity. These drawbacks have made the devices less practical for VR systems.

The new design uses small wax pads filled with scents that are heated by an electrode (电极) to release a smell. A thermistor senses the temperature, which controls the smell's intensity. The study describes two different device formats. The first is small enough that it can be stuck to a user's top lip, but it includes only two smell generators. The second is worn like a face mask and has nine. Both are customizable with a selection of 30 smells, including ginger, clove, mojito and coconut milk. Different combinations can be blended at varying intensities to create thousands of possible fragrances.

The study includes demonstrations of possible applications beyond just enhancing VR, including communicating messages by smell and arousing emotions. The researchers suggest the devices could even be used to ease depressed mood or promote recall in people with age-related cognitive decline. "Scent is directly connected to the emotional and memory parts of the brain, so there are a lot of applications related to well-being and health," Amores says.

To solve this problem, communities are bringing libraries to where the kids are: in the streets. The little libraries consist of boxes that are set up outside of houses or public spaces and are filled with books. People can take books they haven't read and donate ones they have to the libraries.

Street Library Australia, a nonprofit, was started by Nick Lowe after he saw a Little Free Library on a trip to the USA. After an initial workshop in 2015 to build 30 libraries, the idea mushroomed and now there are 4,500 registered street libraries in Australia. "It just grew and grew," he said.

The libraries come in all shapes and sizes. These libraries are completely voluntary and anyone can start one.

Pamela Zielke, who runs a library called Pam's Pantry, gives out toys and craft supplies along with books. An early childhood educator, she started her library with the goal of rescuing books from dustbins. But the libraries are doing much more than just providing books-and other donated items-to people. The street libraries are also building community. "It's a little stopping place outside your house," said Lowe. "It's a great way to meet people in your neighborhood who are also book lovers, recycle books, and find new books."

These Little Street Libraries provided a valuable service during the outbreak of COVID-19 and the popularity has not waned. People use them to find books on specific hobbies like cooking, children are developing a love of reading books, and it is more convenient than going to a bookstore or a brick-and-mortar library. But even more importantly, with a shared interest, the libraries are bringing communities closer together.

A neighbor invited me to tea one afternoon. After listening sympathetically to my sadness, she asked, "Elizabeth, what do you do each week for fun?" I was shocked Fun? "I'm too busy for fun," I said. "Think of something fun to do every week," she urged. I didn't have to think. "I would love to ride horseback," I said.

I found a riding stable (马厩) about 45 minutes away，where I was introduced to Royal, standing proudly nearby. Riding Royal over jumps was a challenge, but we go along well. It lightened my spirit all week;my tasks seemed easier.

Several months passed, and the trainer began working with me to train Royal. The horse had to learn to jump fences in a controlled manner instead of flying over them as he would in an open field. We started with1 small poles and worked our way up to full jumps I arrived at the stable on a particularly cold day. Royal started running. But to my great surprise, as he neared the fence this time, he effortlessly flew over it, jumped another fence into the next field. jumped a third fence, and disappeared into the woods How was I going to find him? How would I catch him if I did find him? Then, as these terrible helpless thoughts raced through my mind, I saw movement at the edge of the far woods. It was Royal, racing toward me!

Royal had found freedom, as I had. But he'd also found love and satisfaction within fences. For him and for me, I realized, fences and freedom had always been a matter of choice.

Here Goes Nothing

Steve Toltz

If you like your fiction left-of-centre, then this book's for you. Angus Mooney struggles for most of his life, until he meets his wife, marriage celebrant Gracie (whose wedding ceremonies are anything but traditional). Just when things are starting to work out, an old guy with a terminal illness breaks into their house and asks to stay until he dies. When Angus does some research on their ‘guest', he wakes up the next day in the ‘afterlife'.

Standing on the edge of the plane, looking at the ground below, my tandem skydiving (双人跳伞) instructor, Bill, turned to face me. "Do you have any last words?" he asked. "Yes," I said, joking. "I hope my parachute opens."

I'd never felt more alive as Bill and I stepped out and started our freefall. Those first few seconds were amazing. I felt like a weightless piece of paper. As we reached 44,000 feet, I felt a parachute open above us. This, I was told, would slow us down for a smooth descent (下降). So why were we still traveling so fast? Confusion turned to panic as I glanced upward: The parachute was flopping (彻底失败) unopened in the wind.

My heart raced. I could hear Bill swearing as he tried to fix whatever had gone wrong.

Seconds passed, which felt like forever, until finally our emergency parachute opened. Except it got caught in the first one, making both parachutes useless. I asked Bill, "Are we going to die?" He said he didn't know.

At that moment, I just felt guilty. I'd brought my family along for the day: my parents, sisters, their partners and children. I'd invited them along to watch me die. I prayed for a second chance, for a miracle that would allow me to go back and redo the moments leading up to the jump. I prayed….

We hit the ground. I was immediately breathless, and an unimaginable pain shot up my back as we bounced into a lake on a golf course. I was somehow still alive. Gathering all my strength, I turned to face Bill. His screams of agony (极度痛苦) filled the air. From neck down, I could barely move.

We were found by some golfers, who quickly summoned emergency services. My mother and sisters cried uncontrollably as Bill was put into a helicopter, and I was placed into an ambulance.

What is the world's (small) country? You could decide to look at populations or the actual areas countries occupy to find your answer. In this case, the answer is same either way: Vatican City.

So, exactly how tiny is this country? Vatican City is a mere 0. 2 square miles (0. 52 square kilometers), is smaller than New York City's Central Park. Nevertheless, it has its own post office, telephone system, radio station, banking system and even its own currency, the Vatican euro. About 800 people live here.

Vatican City is an independent country, it's not recognized by the United Nations. Instead, Vatican City (consider) a permanent nonmember observer, which means it's welcome to sit in the UN's General Assembly and access most UN (serve) and benefits, but it can't vote. And that's just fine with Vatican City.

Unlike Palestine, which has (repeat) applied to become a full member of the UN, Vatican City has never done so. In fact, it's the only nation ever (decline) UN membership. In addition, if it were to apply for membership, the UN might challenge the idea it's a true country. According to the UN's definition, this (include) the ability to assist with global security.

I3 most of the weeks in the classroom, helping the children with their work4 and in groups and also reading with them. I was also extremely lucky to be able to5 them on a range of school trips. We watched a TV program, Horrible Histories, in an old barn, and traveled to Wales to see Roman baths and the ruins of their old barracks (营房). My favorite6 by far was the opportunity to participate in a Christmas carol service inside Bristol Cathedral.

As with all jobs, the fun didn't come without its set of7. A large percentage of the children in the class had special educational needs which, at times, were very hard to manage as I previously had8 experience with this.9, it was so gratifying to learn how to work and form relationships with each of these children in their individual ways. One of my fondest memories is the coach ride back10 Wales when I sat with one student with autism (自闭症). We spent the whole coach ride laughing and singing together,11 our own songs while he tried to convince me to download his favorite video game.

The whole experience was undoubtedly rewarding and something I will always12 on with joy. Even the routine of reading with the children was made fun by the13 of characters and personalities within the class. Working with children can be14, but I am so pleased I was able to have this experience.

During the placement, I learned a lot about patience, understanding, and the joy of seeing children learn and grow. It was15 a life-changing experience.

As cities develop, some sources of carbon emissions (排放) may be hard to notice for most people, for example, the bricks used in buildings. US company Biomason has produced bio-based cement (水泥), which can sharply cut emissions during traditional cement production.

"We grow cement the same way nature does," wrote the company's website. How the cement is "grown" is based on biomineralization, the process by which living organisms produce minerals. One example of biomineralization is coral reefs. Massive reef structures are formed when each individual stony coral produces calcium carbonate, a kind of mineral. Although the stony corals are tiny, one reef structure, built by millions of stony corals, can grow to weigh several tons.

This biobased cement alternative is called Biolith. During the production of each Biolith tile, bacteria and nutrients are mixed with sand. Organisms then produce calcium carbonate by absorbing a liquid made of calcium and nitrogen (氮). However, the process doesn't change the size of the Biolith tile instead, it increases the density. The produced calcium carbonate forms bridges between the grains, strengthening the unit from within. It takes less than 72 hours to let a Biolith tile "grow" fully, while traditional concrete requires about 28 days to make a brick.

The company aims to "remove 25 percent of carbon emissions from the concrete industry by 2030," according to its website. Traditional concrete is made of crushed stones. The process involves heating the stone to temperatures greater than 1,300 ℃, during which carbon dioxide is emitted. The manufacture of Biolith, however, doesn't involve heating, which greatly reduces carbon emissions. The company plans on increasing the use of bio-based bricks, covering 35,000 square meters in Europe by the end of this year.
