Most Impressive Ways to Get from Place to Place

Horse Caravan （马车）

Go a bit old-school with a horse caravan in Ireland. While riding a horse may not offer much in the way of impressiveness, how about getting a horse to a carriage that includes cooking and sleeping areas? That sounds a bit more remarkable. Plus, the horse-drawn carriages allow a fresh perspective on the countryside and beaches.

Terra Bus

Made in Calgary, only roughly 20 of these Terra Bus Ice Explorer all-terrain vehicles exist and they almost all serve the Icefields Parkway and the Athabasca Glacier in Jasper, Canada. Designed specifically for glacier travel, the six-wheel, 49-foot-long vehicle looks like the most robust （强大的）tour bus on the planet. And it is. The Terra Bus Ice Explorer can handle 56 passengers and nearly any sort of ice, mud, sand, snow and rock the Canadian Rocky Mountains have to offer.

The Central-Mid-Levels Escalator （自动扶梯）

If this Hong Kong escalator system didn't exist, you'd have all sorts of stairs to deal with to climb between the western and central Hong Kong districts. This system of 20 escalators, built in 1993, combines to become the longest outdoor covered escalator in the world, running a total length of 2,624 feet and rising 442 feet in the process. From end to encl it's a ride lasting 20 minutes.

Symphony of the Seas

At 1, 181 feet in length and a gross tonnage of 228, 000, the Royal Caribbean Symphony of the Seas is the largest cruise ship in the world. The steel ship features seven distinct on-board neighborhoods, surfing, ziplining, ice-skating, 3D movies and pools. Symphony is powered by solar energy.

In 1985, Tommy Burrell inherited(继承) a piece of land in West Sussex, England, which is 3500 acres. It had been in his family for more than 200 years. As it was a failing farm, he and his wife Isabella Tree, were all set to run a traditional farm, but soon realized the costs far outweighed the profits. The land wasn't suitable for growing crops anymore.

So, in 2001, the couple decided to try something else--an experiment in “rewilding”, or restoring environments to their natural state. They reintroduced native species, including Tamworth pigs, Exmoor   ponies, longhorn cattle, and deer. Then they took out all the fences and let the animals wander freely.

In the following years, the land went through an incredible change. The once neat fields were covered with bushes, creating habitats where new plant and animal species could grow.

Now it's home to many different creatures, including two rare species of bats, nightingales, peregrine falcons, white storks, and even turtle doves, whose numbers have dropped by 98 percent in the U. K. over the last few decades!

“We were living in a biological desert. Now, ecologists are blown away all the time by just the amount of life here," Isabella said. "It shows the potential that this kind of project has for changing trends of biodiversity decline.

What's more, the land is now profitable! Tommy and Isabella offer multiple services there, including walking tours, safaris, photography classes, and rewilding workshops. They also sell meat to control their large animal populations, and even allow visitors to spend a night outside in the tents they set up.

What a promising outcome! This is amazing news for conservationists and shows that our planet can be returned to its natural glory, if only we let it. Now, it's a beautiful reminder of how ecosystems can be restored by letting Mother Nature take the control.

For many white-collar workers around the world, the recent pandemic has meant having to work from home. Their usual office location has been out of bounds . This means different working practices, which have advantages and disadvantages for employees. But the big question is, “Will they ever see their offices again?”

Home working has made people realize what tasks they can perform at home, rather than enduring a commute to the office to do the same thing. It has given them more time with the family; they’ve been sleeping better and have saved money by not travelling or buying lunches on the go . And recent research suggests the majority of people working from home are just as productive.

For some people, this could be a permanent arrangement. In the UK, fifty of the biggest employers questioned by BBC, have said they have no plans to return all staff to the office full-time in the near future. Of course, one main reason is that firms couldn’t see a way of accommodating large numbers of staff while social distancing regulations were still in place. But BBC also heard from some smaller businesses who are deciding to abandon their offices altogether. Other bigger companies are also looking at shutting offices to save money as many jobs can be performed remotely. Peter Cheese, head of the Chartered Institute of Personnel and Development, told BBC: “We’re at a moment of real change in the world of work, driven by big existential crises. ”

But this isn’t great news for everyone. Some employees can feel isolated at home, and there’s less opportunity to network or learn from other people, especially if they’re a new recruit. Also, city centers may suffer most from a change in working habits. Shops and cafes rely on the footfall of office workers, and without them, they face closure. The future is still uncertain, which is why it may be too early to say where our desks will be permanently located. But the office of the future may be your home.

A long-term dream for 3D bioprinting is that people on active waiting lists for organ donations might one day have the option of getting a bio-printed organ. Although the ability to produce a functional heart or kidney this way likely lies years in the future, realistic near-term goals include bioprinting simpler structures. Living tissues printed outside the body, however, would still require implantation operation, which often involves large incisions （切 口）that increase the risk of infection and lengthen recovery time.

Scientists in Tsinghua University are working on a way to print cells directly inside the body. The idea would be to use existing minimally invasive （微创）operation techniques to insert 3D printing tools into patients and then lay down new tissues.

Much of the previous research has focused on treatments of skin and other tissues in the outer part of the body, because the necessary equipment is normally too large to access :he digestive tract (消化道）and other centrally located organs. Scientists in China wanted to develop a mini bioprinting robot that could enter the human body with relative case, so that they can use the technology for conditions like stomach ulcer （胃溃疡）.

The resulting micro robot is just 30 millimeters wide—less than half the width of a credit card — and can fold to a length of 43 millimeters. Once inside a patient's body, it unfolds to become 59 millimeters long and can start bioprinting. The team has constructed clever mechanisms that make the system compact when entering the body yet extend to provide a large working area once past the tight entry. In their experiments， the researchers in China fitted the micro robot onto a long tube that can be inserted through bodily openings and successfully snaked it through a curved pipe into a transparent plastic model of a stomach.
