Hard Numbers: Dog title temporarily revoked, Young Irish adults live with parents, Russian air travelers live in fear, Houthi strikes crush cargo

31: Hold up, dawg. Guinness World Records has temporarily rescinded the title of World’s Oldest Dog that was awarded last year to a Rafeiro do Alentejo guard dog in Portugal that was allegedly 31 when it died (that’s more than 200 human years).

Experts blame a failure to invest in social housing and an overreliance on market solutions, which created incentives for developers to build luxury or short-term rental properties rather than lower or middle-income housing.

The Houthis say they’ll stop when there’s a cease-fire in Gaza, a call echoed by Qatar’s prime minister on Tuesday at Davos.
