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.

When "irregardless" was included in Merriam-Webster dictionary, it caused wide disagreements. “Irregardless” has been in widespread and near-constant use since 1795, when a newspaper called The Charleston City Gazelle of Charleston Ga., first used it. We do not make the English language, we merely record it,“ the dictionary's staff wrote in “Words of the Week”.

The word's definition, when we read it, would seem to be without regard. However, Merriam-Webster defines "irregardless" as “nonstandard” but meaning the same as “regardless”. According to Merriam-Webster, "Many people find 'irregardless' to be a ridiculous word, as the ir-prefix usually indicates negative meaning; however, in this case it appears to make the meaning of ' regardless’ stronger. "

“It's not a real word. I don't care what the dictionary says,” responds author Michelle Ray, who teaches English in Silver Spring, Md. And she says she's still planning to mark “irregardless" as incorrect on her students' work.

An American newspaper the Baltimore Sun published the word in editor John McIntyre's commentary on Saturday: Irregardless' is too a word; you just don't understand dictionaries. People get upset about the dictionary because they think it is some sort of official document. But actually, it's not. It's just lexicographers identifying words that people use and trying to find out how they are spelled, how they are pronounced, what meanings they have and where they came from. "

“The dictionary's recognition doesn't enroll a word as correct in the English language,“ McIntyre says. "It just says this is a word that a lot of people use in English. And here's what we know about it. " So it's a word, but its use is still discouraged in formal writing.

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.
