Omicron, the new coronavirus variant, has made headlines around the world, amid concerns about the efficacy of current vaccines and whether it portends a setback in efforts to combat the pandemic. Our weekly analysis of the most popular data journalism stories on Twitter highlights a story by Spanish newspaper El País analyzing early data on omicron. In this edition, we also feature an investigation into viral fake news and disinformation in Thailand, a data projection on the growth of African mega-cities, and a story on how an artificial intelligence program can judge your music taste.

Gone Viral

In Thailand, news about COVID-19 is some of the most popular content on the internet. But amid the explosion of coronavirus-related material on social media and in traditional outlets, there has been an alarming uptick in disinformation and fake news. An ambitious four-part project by the Bangkok Post digs into the problem and uses data to illustrate how fake news comes in “waves.” The project also discusses the effects of spreading false or misleading information and asks what makes readers click on these headlines.

Tech Funding’s Glass Ceiling

For decades, the tech industry has been dominated by men, resulting in a gender gap both in terms of income and opportunities. The effects of this disparity can be felt in the investment process as female tech entrepreneurs face major challenges when looking to fund their endeavors. The Kontinentalist, an outlet dedicated to telling data stories about Asia, looked at the situation across the region and analyzed data on pitches, investor bias, and who is funding female start-ups.

Rise of Omicron

Omicron has been described as a kind of “Frankenstein” by one Spanish virologist, as a coronavirus variant with more than 50 mutations, particularly on the spike protein, which the virus uses to attach to human cells. It will take time for scientists to study the variant in depth, but the Spanish daily newspaper El País used some early data to show what the omicron virus looks like and to explain how mutations happen.

Changing Patterns in Rainfall and Drought

The weather has become more extreme, causing flash floods, devastating wildfires, and other catastrophes. But the scale of this phenomenon is so enormous many people struggle to comprehend its significance. Numbers help paint a clearer picture. A team of USA TODAY reporters examined 126 years of federal climate data to look for patterns and the reasons behind the changing weather, and then created a tool to look up variation in rainfall and drought based on US zip codes.

Demolishing Historical Landmarks

Every year, at least 150 objects of cultural heritage disappear in Russia. Cities are losing their historical appearance as architectural landmarks and historic buildings are demolished to make space for new buildings. Old towns are suffering the most, according to an investigation by IStories, which looked at data on historical and cultural sites across Russia as well as conservation efforts.

Honeybee Self-Quarantining

If humans want to learn something about fighting a pandemic, they can look to the bees. To prevent parasites from spreading, honeybees avoid each other and segregate behaviors in parts of their hives. The Economist’s graphics team showed the difference between a parasite-free hive and an infected one.

Africa’s Growing Cities

A century from now, most of the world’s 20 biggest urban areas will be concentrated in Africa. A third of the global population will also live in Africa. Five of the most populous African cities — Lagos, Khartoum, Kinshasa, Mombasa, and Abidjan — give an insight into how urban development is transforming the entire continent. The Washington Post visualizes the transformation with this expansive, multimedia data-driven project.

New Pandemic Restrictions

A fourth wave of COVID-19 has forced Austria into a new lockdown and prompted many other European countries to tighten restrictions. This, in turn, has had an immediate impact on businesses such as restaurants, stores, leisure hubs, and the airline industry. The Financial Times examined data from Google’s Mobility Report, Oxford University, and other sources to show how reduced consumer spending has created new challenges for countries in the eurozone.

AI-Powered Journalism

Machine learning offers huge potential. Algorithms are being used in multiple areas including medical diagnosis, image processing, car manufacturing, and banking. Journalism is no exception. Thanks to artificial intelligence, reporters can now analyze massive datasets to empower their storytelling. A piece by highlights some examples of this trend.

Your (Bad?) Music Taste

It’s that time of the year again. You can explore your annual Spotify or Apple Music report and find out what you’ve been listening to the most throughout 2021. Meanwhile, The Pudding has created an AI program to judge your taste in music. Go ahead and try it out. Trust me, you’re going to have some fun.
