Visuals: language speed & density

According to The Economist, languages face a trade-off between complexity and speed. Those packed with information are spoken more slowly, while simpler ones are spoken faster. As a result, most languages are equally efficient at conveying information.

For instance, a Japanese translation of this text would be longer and a Thai one would be shorter, but readers would finish reading it at about the same time.

Black holes support relativity

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.

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.

The so-called "gut-brain axis" is the well-established bidirectional interaction between the gut microbiome and the brain. In other words, the microbiome in our gut has been found to influence many aspects of our brain: stress physiology and psychology, mood, cognition, and behavior.

A novel challenge has arisen from this finding. Namely, how can astronauts stay alert and healthy through their travels?

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.

Around 48 million people have some degree of hearing loss. Given the rise of wearing face masks in public, hearing-impaired people are struggling to understand those wearing ordinary masks as they muffle their voices. One way to solve this problem is to put on masks with clear windows.

When wearing such a mask, people can see your lips, which allows the deaf or hard-of-hearing to lipread and see facial expressions.

Technology has been quite a godsend for fraudsters. In the past, if you wanted to recreate a valuable painting you needed to painstakingly paint it, or if you wanted to open a fraudulent bank account, you had to physically grow a moustache to fool a bank teller. But these days, it's much easier. To beat two-factor authentication, scammers can simply transfer your phone number to a new SIM card and gain access to every penny you own.

Classic Australian lollies Redskins and Chicos are set to be renamed so they don't marginalise consumers, confectionery company Allens has announced.

The decision was made by the brand's parent company, Nestlé, because a redskin is a slang term for Native Americans in the U.S., where it is considered offensive. Chico, which is Spanish for "boy", is also used in a derogatory way.

According to BigThink, a publication focused on education, what consciousness is and where it comes from has absorbed great minds for thousands of years. In today's world, it's a question posed by physicists, cognitive scientists, and neuroscientists. There are a few prevailing theories.

The first is known as materialism. This is the idea that consciousness emanates from matter. In the case of people, by the firing of neurons inside the brain. If you take the brain out of the equation, then consciousness doesn't exist at all.
