Scientists: Moon over the hill at 4.51 billion years old

It turns out the moon is older than many scientists suspected: a ripe 4.51 billion years old.

That's the newest estimate, thanks to rocks and soil collected by the Apollo 14 moonwalkers in 1971.

A research team reported Wednesday that the moon formed within 60 million years of the birth of the solar system. Previous estimates ranged within 100 million years, all the way out to 200 million years after the solar system's creation, not quite 4.6 billion years ago.

Italian woman, 116, seen as last living person born in 1800s

Surrounded by relatives and friends, Italy's Emma Morano greeted with a smile the news that she, at 116, is now the oldest person in the world.

Not only that, but Morano is believed to be the last surviving person in the world born in the 1800s, with a birthdate of Nov. 29, 1899. That's just 4 ½ months after Susannah Mushatt Jones, who died Thursday in New York, also at 116.

Journalists on Friday descended upon Morano's home in Verbania, a northern Italian mountain town overlooking Lake Major, to document her achievement, but had to wait until she finished a nap to greet her.

Graffiti comes of age as elderly Portuguese try urban art

Some are hard of hearing or don't see well, others complain about stiff joints, one is 101 years old. All have become graffiti artists under a project to energize Portugal's elderly.

Learning how to paint graffiti — a form of urban art often associated with unruly adolescents — is bringing cheer and a can-do attitude to pensioners in this rural Portuguese city. Until late last century, Covilha was a thriving textile center but it now has an aged population as the industry declined and the young left to find work.
