A little Spider monkey Estela and her mother Sunshine failed to bond after she was born in January, forcing zoo keepers to step in and care for her to ensure her survival. The baby spider monkey which is native to Central America, is currently receiving six feeds of formula a day and is now slowly being introduced to solid foods. Read more here.

'Boo,' a 9-month-old orphan, plays with a toy during a presentation at the Madrid Zoo and Aquarium, April 14. Boo, the first orangutan born at the zoo, has been adopted by a female orangutan and is bottle fed by one of the keepers.

 According to the Madrid Zoo's website:

He was born on July 5, 2010 and at the end of February, his mother died from a chronic pulmonary disorder. Despite having had this condition for years, she was able to give birth normally and took excellent care of Boo until she passed away. The zoo tried to make sure her death had minimal impact on Boo – they fed him three times a day and started to reintroduce him to his “aunts” in order to make sure he wasn’t imprinted with human behavior.

I have to nominate 'Boo' for our 'cutest-thing-ever.' You can see the other nominees here. Or see more photos of animals in our weekly slideshow, 'Animal tracks.'

Liberal Party leader Michael Ignatieff holds a crying baby at his campaign headquarters in Toronto, April 8, 2011. Canadians will head to the polls in a federal election on May 2.

I’m surprised when I see a politician reach for a baby at a political event. The scene is always ripe with the potential for comically unpleasant pictures. This picture of Ignatieff is good, but Jim Bourg’s picture of President Bush from 2006 is my favorite “baby kissing gone bad" photo. I laugh every time I see it.

This photo made Saturday, Feb. 26, shows Lipan High School girls basketball coach Amber Branson holding her newborn daughter, Leslie, as she celebrates with members of her team in a hospital in Abilene, Texas. Shortly after coaching Lipan to a regional semifinal victory last Friday, Branson gave birth to daughter Leslie. And about 15 hours later, she was back on the bench guiding the Lady Indians to another win and the school's first berth in the Texas state tournament since 2003.

I had just seen these photos move on the wire and was preparing them for the PhotoBlog when the photographer posted a wrenching detail on Facebook that added another layer of depth.

Kait Wyatt clutches a flag during the burial service for her husband, Marine Cpl. Derek Wyatt at Arlington National Cemetery in Arlington, Va., Friday, January 7, 2011. Wyatt, of Akron, Ohio, was killed Dec. 6 in Afghanistan. Wyatt's son was born 24 hours after his wife received the news of his death.

More on Cpl. Wyatt and memories of him in his Ohio hometown can be found at The Akron Beacon Journal:

Akron Deputy Mayor Dave Lieberth said Mayor Don Plusquellic has sent a letter to Wyatt's parents indicating that ''he would like them to participate in a decision about how best to memorialize'' their son in his hometown. . .  Akron officials are also interested in discussing the broader issue of memorializing all those from the city who have died in war, Lieberth said.

''It needs to be bigger,'' he said of the discussion.

There is no single city memorial to honor all who have died, Lieberth said, although there are memorials for the Civil War, World Wars I and II, Korea and Vietnam within the city.

''We need to find a way to remember those who died in service to our country,'' Lieberth said. (full story)
