"Prepare for warp speed." If you're a Trekkie or Star Wars fan, and maybe even if you're not, you've heard about warp drives and probably dreamed of being able to travel faster than the speed of light. It seemed like the stuff of fantasy—until now. Physicist Erik Lentz has come up with a theoretical model of a warp drive that would shorten a trip to the star Proxima Centauri, the closest star beyond our solar system, from 50,000–70,000 years using rocket fuel, or 100 years using nuclear fuel, to just 4 years and 3 months.

The life expectancy of people in Japan has been increasing for the past 65 years. Life expectancy means the prediction of how long people are expected to live. There are many reasons for the increase in life expectancy, such as better food, cleaner water and improved medicine.

Please have a look at the chart below and discuss what you see with your teacher.

The English National Opera (ENO) has teamed up with a London hospital to teach breathing techniques to people recovering from COVID-19. One of the common lingering effects of the virus is difficulty breathing. Proper breathing is essential for opera singers, so they're in a unique position to help patients recover. 

People around the world follow different religions. We use specific words to describe them.

Crossing the street is very easy in most countries. You simply wait for the crosswalk light to turn green. The cars stop and let you walk safely to the other side.

However, in Hanoi, Vietnam, crossing the road is an adventure. There are few traffic lights, and the cars and motorbikes will never stop for you. You need to just walk into the street and the vehicles will go around you. It can be very scary, but that is the only way to cross the street in Vietnam. You have to trust the drivers not to hit you.

Languages generally develop organically, following changes in culture. But sometimes we have to purposefully change our language to create the culture we need.

Take, for example, sexism. In English, seeing the masculine form of a word—e.g., adding "-man" to a job title, and using he/him/his pronouns—as neutral had been accepted as the norm since the 19th century and still often is. In the 1970s, however, women began to demand equal representation in all things, and that meant in the language, too. 

According to The Guardian, a newspaper based in the United Kingdom, Bookshop is a socially conscious alternative to Amazon that allows readers to buy books online while supporting their local independent bookseller.

Christmas is very popular in Germany—lights, food and decorations abound. Also, of course, presents are a main component for many people, especially younger people. But the Germans are famous for being pragmatic and no-nonsense. So what kind of gifts are commonly given in Germany? Read the chart below to find out.

This year has certainly been a rollercoaster. There were highs and lows, not to mention a lot of uncertainty—sometimes all you could do is throw your hands up and hope for the best. 

Looking back on 2020, there are a few things that changed. 

Rice straw, or wara, is the waste left over from rice production. It used to be used to make tatami mats, bags, and other daily goods, including shoes. But these days most things are made from plastic and other synthetic materials, so farmers are left with mountains of useless wara.

The COVID-19 pandemic forced most professionals around the world to begin working from home in early 2020. Suddenly teams were separated and had to communicate over video call services. It’s hard to feel connected that way. And it’s hard to build relationships and maintain the trust that today’s business depends on. 

CNN reports that according to the International Air Transport Association (IATA), providing a single dose of a future coronavirus vaccine to all 7.8 billion people in the world will require the use of 8,000 Boeing 747 cargo aircraft, and that planning needs to begin now.

IATA's director general and CEO, Alexandre de Juniac, said in a public statement that "safely delivering Covid-19 vaccines will be the mission of the century for the global air cargo industry."

The Guardian reports that more than a decade of police crackdowns on major gangs and economic uncertainty are making it harder for the yakuza to tempt young men with promises of easy money.

For the first time since records began in 2006, 51% of regular yakuza members are aged 50 or over, according to a new report by the national police agency. Less than 15% are under 40, and those over 70 account for just over 10% of total membership.

Algae is used in lots of ways, from food to health supplements to fuel. Now we can add flip-flops to the list. Flip-flops, commonly made from rubber, foam or plastic, are hugely popular all over the world. When people lose theirs on the beach, which happens frequently, the flip-flops are swept into the ocean to join the rest of the plastic pollutants collecting there. 

Currently, 34 vaccine candidates for the novel coronavirus are in various stages of clinical development, according to the World Health Organization (WHO). However, the process is long, typically many years. In the race for a vaccine, there is some debate on the merits of rushing through the process.

CNN reports that scientists have created a mouse embryo that's 4% human. The hybrid is what scientists call a human-animal chimera, a single organism that is made up of two different sets of cells. This human-mouse chimera has by far the highest number of human cells ever recorded in an animal.

This opinion is a rant—a passionate, typically angry, speech or piece of writing about one particular topic.

This rant is about American anti-maskers—people who are opposed to wearing a face mask during the coronavirus outbreak. 

The iconic "Sophie" pedestrian crossing signal (pictured above) first appeared outside City Hall in Amersfoot, the Netherlands, in December 2000. Since then, she has inspired female figures on crossing signals around the world. As Dutch Ambassador Wim Geerts said in 2013, "Sophie is much more than a traffic light, as she encourages us to think about women's rights." She also seems to improve pedestrian safety—more people stop for Sophie than for lights with common male figures.

Mascots, or yuru-kyara, are incredibly popular in Japan. There are yuru-kyara for everything, from sports teams to prefectures to a toilet disinfectant (seriously). Now they're offering the world a mascot for the novel coronavirus pandemic.

According to the India Times, in May 1968, a British traveler named Andy Stewart was looking to make his way home to London from Sydney, Australia. So he bought a double-decker bus and converted it into a mobile home, nicknamed "Albert". That October, he set off with 13 others on Albert the Bus for a 16,000-kilometre journey from Sydney to London via India. The journey took 132 days to complete.
