Save energy with new windows

In 1991, researchers at Berkeley Lab invented a triple-glazed window they hoped would revolutionise the building industry. Though windows with three panes had existed for years, what distinguished Berkley’s design from precursors was the presence of a centralised, thin layer of glass. This made the window lighter, as less material could be used to make the external panes. It also made the window more energy efficient, as compartments either side of the central layer could be filled with insulating gas. On paper, the window had the potential to cut annual heating bills by 39 percent and reduce air conditioning costs by 28 percent. The only problem was that it was prohibitively expensive to manufacture.

The History of Planned Obsolescence

On December 23, 1924, a group of international businessmen gathered in Geneva for a meeting that would change the world for decades. Delegates from all major lightbulb manufacturers were present, including the Netherlands’ Philips and the United States’ General Electric. While revellers celebrated Christmas elsewhere in the city, the group founded the Phoebus cartel, a supervisory body that would carve up the global incandescent lightbulb market.

How humanity nearly went extinct

According to NPR, around the year 70,000 B.C., a volcano called Toba on Sumatra Island in Indonesia, erupted, blowing about a thousand kilometres of vaporized rock into the air. It is by far the largest volcanic eruption we know of.

That eruption dropped roughly six centimeters of ash over all of South Asia, the Indian Ocean, the Arabian and South China Sea. With so much ash, dust and vapor in the air, science writer Sam Kean says Toba "dimmed the sun for six years, disrupted seasonal rains, choked off streams and scattered whole cubic miles of hot ash (imagine wading through a giant ashtray) across acres and acres of plants." Berries, fruits, trees, African game became rare. Early humans, living in East Africa just across the Indian Ocean from Mount Toba, probably starved, or at least, he says, "It's not hard to imagine the population plummeting."

The idea of Universal Basic Income

According to Vox Media, the idea of a basic income was, for decades, something of a policy fantasy. However, the last few years have seen it become less fringe and more mainstream. In fact, we now have many limited basic income programs running around the world.

The general idea—that the government should give every citizen a regular infusion of money with no strings attached—has been around since the 16th century. However, the COVID-19 pandemic has given the idea fresh momentum, with the crisis generating significant financial loss and uncertainty.

Critics worry that UBI will disincentivize work and hurt the economy. They also say that it is unaffordable for the government to pay every citizen enough to live on, regardless of whether they work. So far, the evidence has not supported these critiques.

Diversity of research sources

According to PhysOrg, a scientific publication, scientific knowledge used in international studies is predominantly sourced from English-language documents, as it is assumed that all scientific knowledge is available in English. However, according to research scrutinizing over 400,000 peer-reviewed papers in 326 journals, published in 16 languages, scientific papers written in languages other than English may hold untapped information crucial to the conservation of global biodiversity.

These findings have important implications for global efforts tackling the biodiversity crisis, where lack of evidence is an issue commonly faced when trying to implement evidence-based conservation. The authors demonstrate that incorporating non-English-language studies can expand the availability of scientific evidence on species and ecosystems into 12%–25% more areas and 5%–32% more species.

When you become your career

According to the Harvard Business Review (HBR), many people with high-pressure jobs find themselves unhappy with their careers, despite working hard their whole lives to get to their current position. What happens if you identify so closely with your work that hating your job means hating yourself?

Psychologists use the term “enmeshment” to describe a situation where the boundaries between people become blurred, and individual identities lose importance. Enmeshment prevents the development of a stable, independent sense of self. You can become enmeshed with your career, too.

The work culture in many high-pressure fields often rewards working longer hours with raises, prestige, and promotions. Also, certain careers or career achievements are often highly valued in an individual’s family or community. When high pressure jobs are paired with a big paycheck, individuals can find themselves launched into a new socioeconomic class.

Toyota's struggles with EVs

Toyota was the leader in eco-friendly hybrid vehicles for many years, according to ArsTechnica. The automotive company had a fuel-efficiency edge over its competition. However, it has recently struggled to compete with companies that sell electric vehicles such as Tesla, Nissan and Volkswagen.

Toyota has made two critical choices. First, it tethered itself to hybrids. Second, it bet its future on hydrogen. But now governments around the world are moving to ban fossil-fuel vehicles of any kind.

Earth's new ocean

According to the National Geographic Society, Earth now has a new ocean: the Southern Ocean.

Geographers have debated whether the waters around Antarctica had enough unique characteristics to deserve their own name, or whether they were simply cold, southern extensions of the Pacific, Atlantic, and Indian Oceans. 

With a range stretching the circumference of Antarctica to the 60-degrees South latitudinal line, the Southern Ocean “encompasses unique and fragile marine ecosystems that are home to wonderful marine life such as whales, penguins, and seals,” explains National Geographic’s Enric Sala. The region includes such creatures as migrating humpback whales and many different seabirds.

Visuals: Falling sperm count

In 2017, Shanna Swan and Hagai Levine, along with six other researchers, estimated the average sperm count for 43,000 men in 55 countries across the world. The data, from 185 previously published studies, suggest that sperm counts fell by about 25% between 1973 and 2011. They found that sperm counts had in fact fallen by about 50% in Western countries over the period. Although the data were less plentiful, similar trends were observed in developing countries, too.

Murakami's "First Person Singular"

National Public Radio (NPR), a publicly-funded American news organization, held an interview with the famous Japanese author Haruki Murakami about his new collection of stories, First Person Singular. In this collection, Murakami writes in the first-person singular “I” perspective.

Murakami said, "There's a long tradition in modern Japanese literature of the autobiographical, so-called I-novel, the idea that sincerity lies in honestly and openly writing about your life, making a kind of self-confession. I'm opposed to that idea and wanted to create my own 'first personal singular' writing."

Murakami goes on to explain that he often writes characters based on his personal experiences and rewrites them multiple times to the point that the experiences become fictional and hard to recognize from his own life.

Digital privacy and advertisements

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.

By micro-profiling audiences and monitoring their behavior, digital-ad platforms claim to solve advertisers’ problem of not knowing which half of their budget is being wasted. According to Group M, the world’s largest media buyer, in the past decade, digital ads have gone from less than 20% of the global ad market to more than 60%.

What is great listening?

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.

HBR analyzed data describing the behavior of 3,492 participants in a development program designed to help managers become better coaches. The study concluded that good listening is much more than being silent while the other person talks.

People perceive the best listeners to be those who periodically ask questions that promote discovery and insight. Good listening also includes interactions that build a person’s self-esteem. The best listeners make the conversation a positive experience for the other party, which does not happen when the listener is passive.

The ancient giant shrimp

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. 

It grew up to 182 centimetres (almost 6 feet) long and had eyes with thousands of lenses, which gave the Anomalocaris extremely sharp vision. It was a fast swimmer, and once it caught up to its prey, the creature could grab it using front limbs equipped with sharp spikes on each segment. This combination of excellent vision, speed and spiky front arms would have made it a formidable predator.

The Anomalocaris’ mouth was composed of 32 overlapping plates. Some scientists interpret this as meaning that it could easily crush prey.

The ego's effect on leadership

According to the Harvard Business Review, the higher leaders rise in the ranks, the more they are at risk of getting an inflated ego. The bigger their ego grows, the more they are at risk of ending up in an insulated bubble, losing touch with their colleagues, the culture and ultimately their clients.

An unchecked ego can warp our perspective, twist our values and corrupt our behavior. When we believe we’re the sole architects of our success, we tend to be ruder, more selfish and more likely to interrupt others. An inflated ego also narrows our vision. The ego always looks for information that confirms what it wants to believe. Basically, a big ego makes us have a strong confirmation bias.

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.

The black hole in this study is 6.5 billion times more massive than our sun. The research team measured the distortion in the black hole’s gravitational pull and found that the size of this black hole's shadow aligns with the theory of relativity, or matter warping space-time to create gravity.

While the theory of relativity has passed all of the tests thrown at it over the past century, further study is needed to confirm whether it continues to match up with astrophysical objects.

Where does consciousness come from?

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.

The second theory is mind-body dualism. This is perhaps more often recognized in religion. Here, consciousness is separate from matter. It is a part of another aspect of the individual, which in religious terms we might call the soul.

An explosion of stellar proportion

Global News, a Canadian news outlet, reported that astronomers detected an explosion over fifteen times the size of our galaxy. This makes it the biggest blast ever recorded.

The massive explosion occurred hundreds of millions of light-years away, where a supermassive black hole emitted large amounts of energy and matter while devouring a galaxy, blowing a hole in space that’s 2.58 million light-years across. It wiped out trillions of stars and tore through the surrounding galaxies. Researchers spotted the hole from the colossal gap it left in the middle of a cluster of galaxies.

The blast occurred in the Ophiucus cluster, a collection of galaxies some 390 million light-years away. It’s unclear exactly when the explosion happened, but researchers say it was definitely millions of years ago.

Rare giraffes come under threat

According to National Geographic, the remains of two white giraffes were found in a nature conservancy in northeastern Kenya. The giraffes likely had a rare genetic condition called leucism, which inhibits skin cells from producing pigment. It is believed that they were killed by poachers.

The animals had been well-known since 2017, after rangers spotted them in the conservancy and posted a video to YouTube, which then went viral.

This highlights a modern-day paradox: social media allows people to experience the joy and wonder of the planet’s rarest creatures while simultaneously putting animals at increased risk. Rarity and exclusivity are among the driving factors of the illegal wildlife trade, so unusual animals are more likely to be targeted by poachers.

National Geographic concluded that navigating how to report on unique animals without helping to put a target on their backs is a delicate process. 

Bans on cashless stores

The cashless economy has become increasingly prevalent in developed countries such as the U.S. and Japan. Consumers are incentivized to use debit or credit cards through discounts and freebies, and banks and credit card companies collect information on people’s spending habits.

Some stores in the U.S. have decided to stop accepting cash from customers altogether, which has resulted in a backlash. Millions of people, most of whom live below the poverty line, do not have a bank account and only deal in cash. Advocates have argued that the cashless economy discriminates against poor people and the homeless.

American cities and states have started banning cashless stores on the grounds that they are discriminatory. San Francisco, New York City, Washington, D.C., Philadelphia and New Jersey have recently passed legislation forcing stores to accept all types of legal tender.
