Prediction Markets, Hatching Extinct Species, and Boy Kibble

 Need To Know 

Which Came First, the Moa or the Egg?

Colossal Biosciences says it has developed a 3D-printed artificial eggshell that successfully hatched 26 chickens, a step toward the company’s efforts to revive extinct species like New Zealand’s 12-foot-tall, flightless moa. (What drove them to extinction roughly 600 years ago?)

As the largest single cell in nature, an egg acts as a self-contained incubation system, protecting and sustaining a developing organism without a living womb. Natural eggshells are only about 0.4 mm thick and contain membranes and microscopic pores that allow embryos to breathe while keeping out bacteria. Colossal’s version replicates that structure using a rigid shell and a hexagonal, silicon-based membrane, allowing embryos to exchange oxygen and carbon dioxide.

The company, which previously drew attention for its work on the dire wolf, says the technology could eventually scale from chickens to emus and, one day, the moa, whose fully developed egg is roughly 80 times larger than a chicken egg. See the company’s de-extinction “to-do” list.

Prediction Market Showdown

The Trump administration yesterday sued Minnesota over a first-of-its-kind statewide ban on prediction markets such as Kalshi and Polymarket. 

The Minnesota law, passed Monday and effective Aug. 1, makes it a felony to operate or advertise prediction markets, which let users wager on outcomes of future events ranging from sports games to elections. The measure passed the state Legislature with broad bipartisan support, with lawmakers expressing concern that the fast-growing online markets constitute an unregulated form of gambling. 

With the exception of tribal-owned casinos and horse races, gambling and sports betting are illegal in Minnesota. The Trump administration contends that prediction markets are federally regulated financial instruments rather than gambling products typically overseen by states. Explore how sportsbooks and prediction markets differ here. 

Together, Kalshi and Polymarket generate about $25B in monthly trading volume, up from $2B a year ago. Play with this simulator to understand how wagers work. 

Mango Heir Arrested

The son of fashion retailer Mango cofounder Isak Andic was arrested in Spain yesterday in connection with his father’s death. 

Isak and his son, Jonathan, were trekking in Montserrat Natural Park in December 2024 when the 71-year-old fell roughly 500 feet into a ravine. Mango issued a press release that day characterizing Isak’s death as an accident, and police closed the probe after several weeks. However, they reopened the case in March 2025, and in September, a judge changed Jonathan’s status from witness to possible suspect. See the spot where Isak fell, from a hiker’s perspective.

Isak was born in Istanbul in 1953. After moving to Spain at age 14 in the 1960s, he began selling hand-embroidered T-shirts imported from Turkey to his classmates. In 1984, Isak opened the first Mango store, which has today expanded to around 3,000 outlets in 120 countries. See a new Mango ad, featuring Hailey Bieber. (w/video)
