The perplexing Battle of Los Angeles in 1942 generated swaths of UFO conspiracies

On Feb. 24-25, 1942, weeks after the Pearl Harbor attack, a US military radar warned of enemy aircraft. A citywide blackout went into effect, powerful searchlights were lit up, and US forces fired artillery at what they believed to be the enemy. However, no confirmed enemy planes were ever identified. Eyewitnesses reported seeing large objects flying overhead, and much of the public speculated about UFOs and extraterrestrial attacks.

Pineapple research helped scientists solve Los Angeles' smog mystery

In the 1950s, chemist Arie Haagen-Smit applied methods he'd used studying pineapple plant chemistry to smog-filled air—discovering that sunlight reacting with car exhaust produced photochemical smog from hydrocarbons and nitrogen oxides, not factory smoke.

Biologists believe over 5,000 coyotes inhabit LA as of 2025

Panic and fear of coyotes spread in the 1980s after the first recorded instance of a human killed by the animal in American history, but LA and Chicago residents today are learning to live alongside the animal. Research shows that coyotes can even benefit urban ecosystems by helping to control populations of geese and deer, and by improving songbird survival through preying on cats.

Although surveillance is viewed as necessary for enhancing morality and enforcing regulations, many citizens adopt mental tactics to distance themselves from it. Surveillance is linked to China's historical "century of humiliation," following the Opium Wars and Japanese invasion.

How the US first installed an electronic fence along the southern border

The US Border Patrol's first automated surveillance system launched in 1970 with 177 ground sensors installed along a single section in California. The sensors had already been used in Vietnam, along the so-called McNamara Line, and were connected by radio transmitters to magnetic-tape computers. They were implemented to target people defined by law and deportable aliens.

Governments around the world are struggling to measure loneliness

Funding for policy resources often hinges on measuring the scale of a problem and then being able to measure the effectiveness of interventions, requiring data. Yet defining and measuring loneliness at a country-scale remains challenging. Typically, the University of California Los Angeles Loneliness Scale is sometimes used worldwide or adapted to measure loneliness.

Despite privacy risks, scientists are using DNA in the air to assess ecosystem health

While DNA in soil and water samples has long been used for such analyses, airborne DNA is being incorporated into such efforts to monitor individual species abundance, detect invasive species, measure biodiversity, and determine the success of conservation actions. Future work may include detecting attacks from biological weapons.

The crypto city home to biohacking experiments

The DIY nature of biohacking gives the work an entrepreneurial feel, as seen by the emergence of community labs, at-home testing kits, and corporation-backed cities that don't necessarily require government-approved testing standards. Próspera, Honduras, created by a business of the same (first) name, was born from legislation that allowed international businesses to shave off a slice of the country to establish their own micronations.

A sociologist makes the case for libraries and parks as essential public infrastructure

Eric Klinenberg argues that social infrastructure that brings people together is as vital to a community as roads or power grids. He contends that when communities invest in these spaces, residents grow more connected, and when they are neglected, isolation follows.

Palantir's services allow both companies and the government to analyze complex data

There's a common misconception that Palantir buys, sells, and shares data, but Palantir insists it isn't a data broker. Rather, Palantir is more like a data analytics company that allows corporations and government agencies to combine messy, large, and often hard to access datasets to gather insights.

The Greek city of Alexandria in Egypt helped form the template for modern cities

It was designed by Dinocrates, who studied under Hippodamus, the father of urban planning. Hippodamus preached that urban planning should take into account function, culture, and politics. Dinocrates' design of Alexandria meant applying Hippodamus' teachings on a scale never before attempted.
