According to The Economist, in April 2021, Apple, which supplies one-fifth of the world’s smartphones and around half of the United States', introduced a software update that will end targeted advertisement by companies. Its latest mobile operating system forces apps to ask users if they want to be tracked. Many are expected to decline. It is the latest privacy move forcing marketers to rethink how they target online ads.

Vaccination against the COVID-19 virus started in December 2020. It has progressed at an unequal rate around the world. As of late April 2021, only a few million people had received a vaccination in the whole of the African continent, while over 200 million Americans had been vaccinated.

However, for some smaller countries, the situation can change very quickly.

According to the Harvard Business Review (HBR), people often think they are better listeners than in actuality. They believe good listening means just a few things: not talking when others are speaking, letting others know you are listening through facial expressions and verbal sounds (e.g., Mm-hmm), and being able to repeat what others have said.

According to Shape of Life, an online resource on everything related to animals, the Anomalocaris (ah-NOM-ah-LAH-kariss), from the Greek meaning “unusual shrimp”, was a major predator of the ancient seas during the Cambrian Explosion 530 million years ago. 

Will.i.am of the Black Eyed Peas has designed a high-tech face mask that looks like something out of a sci-fi movie. Called Xupermask, it has three dual-speed fans to keep you cool, and a design to keep you looking cool. The real money-grabbers are noise-canceling headphones, LED lights for nighttime, and Bluetooth capability. You can listen to music, take and make calls, and put on your own light show while wearing this thing. It doesn't come cheap, but at $299, it costs less than a set of Bose headphones, and a lot less than a mobile phone!

Bloomberg News reports that according to Microsoft's Work Trend Index, which polled 30,000 people from a variety of companies in 31 countries and used trillions of data points, the majority of workers feel they are struggling or just surviving in pandemic work conditions and a large percentage are considering leaving their employer this year.

Here in Melbourne, Australia, we are heading into the colder months. 

Daylight Saving has just ended, so we moved our clocks back an hour. On the plus side, we all got an extra hour of sleep over the weekend. But it also means the sun sets an hour earlier. 

If I want to catch the daylight, I have to walk the dog earlier. I also have to put better lights on my bicycle because I'm cycling more often around twilight and dusk.

"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 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. 

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. 

An interesting situation has emerged in the American stock market. It has caused the stock of several companies to be extremely volatile.

Hedge funds in the US have opened so many short positions—basically, they have bet that stock prices will fall. Now it is believed that they have short sold more than the number of shares available on the market.

However, savvy retail traders noticed this. They started to buy up these shares in large volumes in the hope to push up the price.

Human beings are flawed. So no system of defense that depends on human action is going to be able to protect us 100% of the time. But we can prevent most problems. In 1990, Professor James Reason came up with the "Swiss Cheese model" to create defenses that are hard to break through.

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. 

Albert Einstein spent nearly a decade developing his theory of general relativity, which he published in 1916. The theory asserts that gravity is matter warping space-time and so gravitational bends in space can alter the passage of time. While an appealing theory, it is yet unproven.

According to CNN, the first image of a black hole, captured in 2019, has revealed more support for Einstein's theory. The new finding has suggested his theory is now 500 times harder to disprove.

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.
