Two lighter stories: a golden retriever found alive after months lost in the mountains, and China showing off humanoid robots that are impressive and a little unnerving.

• Milo, a Nevada golden retriever, ran off on Christmas Day after a sheriff's deputy's horn spooked him near Lake Tahoe.
• He survived 72 days in the wilderness and lost 45 pounds before a woman walking her own dog found him near Carson City.
• His microchip is what got him back to his family, and it also earned him the Hambone Award for unusual pet insurance claims.
• At Beijing's World Robot Conference, more than 300 companies are showing 3,000 exhibits, some of them close to human-looking.
• The machines move factory parts, serve food, fold laundry, offer companionship, play table tennis, box in a ring, and dance.

Outlook: China's robot makers are pushing humanoid machines toward everyday work, and the gap between demo and workplace is closing fast.
