According to CNN, learning a new language can rewire your brain and help stave off Alzheimer’s disease later in life. Ellen Bialystok, from York University in Toronto, Canada, found that bilinguals are diagnosed with Alzheimer's disease four to five years later than their monolingual counterparts.

When it comes to the beneficial effects bilingualism has on the brain, education levels do not matter. In fact, the most profound effects were found in people who were illiterate and had no education. Bilingualism was their only real source of mental stimulation, and as they got older, it provided protection for their aging brains.

More experience with bilingualism leads to greater cognitive changes. The earlier you start being bilingual, and the more intense your bilingual experience is on a daily basis, the more changes happen in your brain.

The Atlantic reports that though success isn’t a conventional medical addiction, it has addictive properties for many people. Praise stimulates the neurotransmitter dopamine, which is connected to addictive behaviors. Success addiction is known to have a negative effect on human relationships. People choose to travel for business on anniversaries, and they miss their children’s important milestones while working long hours. Some even decide to focus on their careers and forgo marriage.

Many scholars, such as the psychologist Barbara Killinger, have found that people are willing to overwork to keep getting "hits" of success at the expense of their well-being. They shelve a much-needed rest from work and time with family and friends until after a project, or a promotion, but that day never arrives.

According to The New York Times, research shows that close friendships are necessary for optimal health and well-being. A key to close friendship is intimacy, and a big part of intimacy is being able to be fully yourself and be understood by others.

If close friendships really are vital to people’s well-being, one might assume we would be able to make them easily. However, it turns out that the opposite may be true: close friendships are important to people because they are so difficult to form.

According to John Cacioppo, a social neuroscientist, humans evolved a natural bias against easily making friends because, in the past, avoiding an enemy was more important than making a friend. If a person mistook a friend for a foe, then that would not endanger their survival, but mistaking a foe for a friend could lead to death.

The standard measure of economic performance, the gross domestic product (GDP), measures the value of goods and services produced within a country over a given period. However, the GDP doesn’t measure social factors like income inequality, domestic violence, drug addiction, or the impact of today’s actions on future generations. It also ignores sustainability and environmental destruction. It’s a very short-term view of market factors without respect to what’s happening on the social and environmental levels. As a result, the GDP gave us no warning of the impending global financial crisis in 2008.

But we continued to base our economic predictions on that metric. And it began to show economies recovering and growing—so everything’s going well again, right? But what if we factor in social and environmental realities?

English is a modern lingua franca. It is a leading language in so many areas: from global affairs and science to entertainment. One of the reasons for that lies in the colonial history of the British Crown in the 17th century, when the British Empire became the biggest empire in history. With colonialism, trade relations boomed, following the progress in science, industrial manufacturing and literature. However, there were many other competing languages, such as French, Spanish and German. To know more about how English won the competition against other languages to become a global communication tool, watch this short part of the video, "Why Did English Become the International Language?" 

Floating solar farms, also known as "floatovoltaics," are an efficient way to collect solar energy. They have a number of advantages over land-based systems:

1. They don't occupy land that could be used for other things, like crop farming.
2. They're up to 16% more efficient because the water keeps them cool.
3. They reduce evaporation on hydroelectric dams, saving more water for hydropower.

But they also come with an environmental cost: the panels sit on plastic floats. So far, floatovoltaic developers have relied on virgin (new) plastic to keep the panels afloat. As we know, plastic is one of the biggest contributors to pollution, uses fossil fuels to manufacture, and is deadly for sea creatures. But a new floatovoltaic farm in Alqueva, Portugal, is under development by the EDP corporation, an energy company committed to sustainability. 

In late April, the Indonesian government announced a temporary ban on exports of crude palm oil and its refined products, such as cooking oil. The decision came as a surprise to commercial goods traders as the government had previously stated the ban would only apply to refined products. After the government’s initial statement, prices of crude palm oil significantly fluctuated given uncertainties about what products the ban would cover. Prices have again skyrocketed in light of the most recent announcement.

Since the beginning of the war in Ukraine, the world has seen a wave of food protectionism, as governments seek to protect domestic food supplies in light of surging agricultural prices. As the world’s largest edible oils shipper, providing one third of global supplies, Indonesia threatens to worsen global food inflation with its decision and raises the risk of a full-blown hunger crisis.

To prosper in the digital age, companies must undergo two types of digital transformation. Firstly, they need to become digitized. Secondly, they have to become digital.

Though both transformations depend on new technologies, they require different strategies and rules to implement. Digitization requires companies to update their operational backbones. In the past, core operations, such as delivering goods and services, maintaining accounts, and completing back-office processes, were handled by people. These days, however, they can be enabled by software-as-a-service. In addition to digitizing themselves, companies also need to become digital, which means creating a digital platform for the company’s digital offerings. Not only does this facilitate business development and connection with partners and customers, it also allows companies to better target revenue growth.

Worldwide, democracy and global freedom have been declining since 2006. The COVID-19 pandemic made things worse, with many leaders choosing to use authoritarian measures to contain the virus. It was difficult for the opposition to protest the measures because they weren't allowed to gather in groups.

But the trend towards dictatorship began long before the pandemic. The decline is not just happening in nations with authoritarian governments, but even long-standing democracies have suffered. In 2020, nearly 75% of the world’s population lived in a country where democracy deteriorated. The United States, which has long stood as an icon of democratic values, is becoming so divided that the government can barely function. The 2020 election results were challenged, ending up in an attack on the Capitol building itself.
