The mother of four baby peregrine falcons takes off from the George Washington Bridge, over the Hudson River, in New York, Tuesday, May 21.

Four peregrine falcon chicks, born three weeks ago atop the George Washington Bridge in Manhattan, were fitted with their official tracking bands on Tuesday, before they are old enough to fly the coop. Their specially built nesting box is located just six feet below the bridge’s lower level and high above the Hudson River.  Their parents are among 20 pairs of peregrine falcons living in New York City.  Full story

Sheriff Joe Arpaio explains a typical meal served to convicted killer Jodi Arias and all the other inmates at the Maricopa County Sheriffs Office Estrella Jail, during a news conference, on May 16, 2013, in Phoenix.

Jodi Arias has spent the past four years in cell B403 of the Estrella Jail in Phoenix. The room is located in the maximum security section of the jail, offering only the basic necessities – including a toilet - for 23 hours a day. She has been able to maintain an active presence on Twitter because when she speaks to friends on the phone, she will ask them to tweet on her behalf.

Sheriff Joe Arpaio showed her cell and its belongings to reporters, and said “I’m not going to ask her for her permission, I run this hotel. She doesn’t."

Arias receives one “sack lunch” and one “hot meal” each day, totaling 2600 calories.

Italian businessman Marcello De Finizio stands on the dome of St Peter's basilica to protest against austerity measures on May 21, 2013 at the Vatican.

A man climbed onto a ledge on the dome of St Peter's Basilica on Monday and unfurled a banner protesting against a "political horror show," an apparent reference to Italy's embattled coalition struggling with recession and high unemployment.

Identified by police as Marcello Di Finizio, the man unfurled a white banner reading "Stop this massacre!" in English, scrawled in black and red ink, with "Help us Pope Francis" in Italian.

Di Finizio, who was still on the ledge on Tuesday, has staged similar protests in the past. Last October he stayed overnight on the dome with a banner criticizing multinationals, Europe, and former Prime Minister Mario Monti. Read the full story.

On Sunday, twisters killed two men in Shawnee, Okla., ages 79 and 76, and injured 21 others. The state medical examiner confirmed the second death Monday morning.

“You can see where there’s absolutely nothing, then there are places where you have mobile home frames on top of each other, debris piled up,” Mike Booth, the sheriff of Pottawatomie County, Okla., told The Associated Press. “It looks like there’s been heavy equipment in there on a demolition tour.”

Decorated gnomes designed by celebrity figures Alan Titchmarsh, Elton John, Julian Fellowes and Lily Allen are displayed at Chelsea Flower Show on May 20 in London, England.

For this year only, the Royal Horticultural Society lifted its 100-year ban on garden gnomes and other "brightly coloured mythical creatures" at the Chelsea Flower Show in London England to celebrate its centenary year and raise funds for the next generation of gardeners.

The RHS invited celebrities including Elton John, Judi Dench, and Dolly Parton to paint and decorate gnomes to feature at the world famous gardening event, before auctioning the gnomes online to raise funds for the RHS Campaign for School Gardening.

Gnomes have been banned from the Chelsea Flower Show and other prestigious gardening events because many believe they are tacky and detract from tasteful garden design. Gnome supporters accuse event officials of snobbery.

Residents in downtown Wichita, Kan., were told to seek shelter Sunday afternoon after a tornado was confirmed on the ground – with its presence cloaked by think clouds and heavy rain.
