Globe transportation reporter Eric Moskowitz talks about his experience testing the bike-sharing program in Washington, D.C., as Boston prepares to launch its own program. He says it might catch on here.

Globe reporter Akilah Johnson talks about Governor Deval Patrick's visit this weekend to the Big Apple Circus.

Globe reporter Akilah Johnson talks about a first-grade student at the Henderson Inclusion Elementary School she wrote about earlier this week. Anthony Curioso, who is 8 years old, is a "politician in the making,'' Johnson says.

They may be wearing tuxedos, but that won't stop them from nipping at you. That's what Boston Globe reporter David Filipov found out recently when he spent some time in the penguin tank at the New England Aquarium. He was writing a story about the Aquarium playing matchmaker to stave off penguin extinction. Here he gives the inside scoop on what it's like to be inside the tank

John Blanding of the Globe captured this picture of teenyboppers screaming their hearts out Tuesday night at the TD Garden in joyous anticipation of a concert by heartthrob Justin Bieber. Here are some of his thoughts on getting the shot:

When you're shooting a concert like that you always wear earplugs. The screaming wasn't as loud as I anticipated, but I also didn't take the earplugs out. I learned a lesson about earplugs from a Rolling Stone concert in the 1990s where I literally couldn't focus the camera because I had to hold my ears.

What happens is that photographers are usually restricted to the first three songs. In this case, we're shooting from the photo pit. You take pictures of the crowd and then have to turn around to shoot the show. Following the action during a concert can be tricky. In sports games, you always know they're going to the goal. When it's dancing on stage, you don’t know where they're going.

During the moment I shot the picture, they were showing on the screen a countdown clock to the start of the show. That was in the final seconds. I shot other pictures of the crowd. That first one, the anticipation, was the best.

I tried to hide it behind my beer. But there's no hiding a giant, garish yellow can with "Four Loko" splashed across it, and the guy behind the counter couldn't help but smirk.

"Usually, we have to card people who buy these," he said, chuckling at his wit.

Sure, I've been out of college for more than 15 years -- not exactly Four Loko's target demographic. But I had written recently about the controversy over the high-alcohol drink known on college campuses as "blackout in a can," and was curious to see what all the fuss was about.

Packing 12 percent alcohol and a solid jolt of caffeine into a 23-ounce container, the potent, low-cost malt beverage has become extremely popular among young drinkers.

But after alarming incidents in Washington and New Jersey where a number of students who drank Four Loko were hospitalized with alcohol poisoning, college administrators across the country have warned students to abstain. Last week, alcohol regulators in Michigan banned the drink altogether.

Stan Grossfeld of the Globe captured this startling picture of people on the beach in Nantucket as Hurricane Earl bore down on the state. Here's how he got the shot:

I'd like to say that the picture was a result of hours of dogged hard work, driving around the island researching the churning waters of Nantucket. But the reality is that I was trying to be on vacation.

I knew when I saw the hurricanes forming in the Caribbean that one would head straight toward Nantucket. That's Murphy's Law. I also knew firsthand that the waters were getting rough. I had just gotten my butt kicked by one of those waves that had flipped me over underwater and deposited me on the beach like I was a piece of seaweed.

So I toweled off, made sure there was no more ocean water dripping out of my nose, then I reached into the big cooler and pulled out my trusty camera. I keep the camera and big telephoto lens there because just a few grains of sand can ruin your equipment and turn auto focus into out-of-focus.

The Globe's Jim Davis is best known for his shots of Boston's professional sports teams, but he caught this eerie picture -- of dark figures moving through the snow -- when he pitched in to cover a Feb. 16 storm. Here's how he got the shot:

There's not much to tell about the snow picture from Seabrook Beach, N. H. ... I was cruising around the Salisbury-Seabrook-Hampton area looking for weather pictures. The forecasts on the radio indicated that area would probably be the hardest hit from this particular storm. I didn't see many people as I drove.

While turning a corner on Manchester Street in Seabrook, I finally saw a group of what appeared to be teenagers walking towards the beach. By the time I could safely find a place to park and grab my cameras and get out of the car, the group had already made it to the beach, and after walking briefly southward in blinding snow and wind, turned back towards the street, now being on the other side of a dune from me.

With a 70-200mm zoom lens, I shot a few frames through the blowing snow flakes. Due to the conditions, it appears almost as if the picture were shot in black and white. The high ASA rating on my camera due to the low light conditions added to the grainy quality.

Inspired by rock and roll -- Republican candidate Charlie Baker

By Martin Finucane, Globe Staff

It happened just after his formal announcement for governor this weekend at historic Faneuil Hall. Republican Charles D. Baker Jr. thanked everyone for coming. And a rock and roll guitar began playing on the sound system.

Then, with his sharply creased suit and his perfectly tied tie, Baker grabbed hold of the air as if it were an invisible guitar and began strumming it, giving it three mighty windmill-like strokes. He looked more like a late night host than the former health insurance executive and government official that he is.

Globe photographer John Tlumacki, who caught the air guitar moment with a burst of frames on his digital camera, said Baker was much more animated Saturday than he was at an event several months ago when he first announced he was running and barely lifted his hands to gesture.

"It was just -- wow," said Tlumacki.

Patriotism runs deep in Charlestown, and this video by the Globe's John Tlumacki, which accompanies a column by Kevin Cullen on today's Metro front, captures that spirit of love of country.

Cullen writes: Charlestown is one square mile. From that square mile, 5,000 men and 100 women went off to war in the 1940s, and 94 men and two women didn’t come back. Gold Stars hung in windows from City Square to Thompson Square, all the way down to the Schrafft’s factory in Sullivan Square. In the other windows, mothers pulled back curtains, watching their kids walk down to the Navy Yard, waiting for them to return.
