input: Make use of the article to answer the questions. NEW YORK (CNN) -- A 14-year-old girl disappears on her way home from school, another is last seen near her home and a 16-year-old vanishes after leaving her fast-food job for the day.

Amanda Berry is shown near the time of her disappearance in 2003, and how she might appear today.

All from the same neighborhood in Cleveland, Ohio, the girls disappeared within five blocks of each other over a four-year span, starting in 2003.

Agents and detectives from the FBI and Cleveland Police are looking into hundreds of leads in the cases and whether they may be linked, according to FBI Special Agent Scott Wilson in the agency's Cleveland bureau.

"We kind of put all three of these cases together to work them to see if there's any connection," Wilson said.

Amanda Berry, 16, vanished on April 21, 2003, after she left her job at a Burger King at about 7:30 p.m. But she never made it to her home just a few blocks away, the FBI says. Berry has pierced ears, a pierced left eyebrow and a scar on her lower abdomen. She would now be 22.

Georgina DeJesus was last seen at a pay phone around 3 p.m. on April 2, 2004, as she headed home from school. She and a friend had called the friend's mother seeking permission for a sleepover at DeJesus' house, but the answer was no.

The girls then parted ways, and DeJesus was never seen again. She was wearing a white jacket, a sky blue sweater, blue jeans and a cream shirt. She has a light birthmark on her right leg and pierced ears, the FBI says. DeJesus was 14 when she disappeared and would now be 19. 1. Where did Amanda Berry work?

input: Darek Fidyka, a 38-year-old Bulgarian, had been paralyzed from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted them into his back and re-grew his spinal cord . Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey.

The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal nerves, the only part of the nervous system that constantly re-grows. "The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself," Professor Raisman said.

Polish doctors injected the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves.

Professor Raisman achieved this with rats in the late 1990's, but this is his greatest success. "I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn't control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true."

Doctors chose the easiest case for their first attempt--it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized.

David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe.

"What you've got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday," he said. 1. What did doctors put in Fidyka's spinal cord?

Q: (CNN) -- A magnitude-4.4 earthquake rattled residents of southern California early Tuesday morning, according to the U.S. Geological Survey.

There were no immediate reports of damage or injuries, authorities said. However, police and fire officials said they had received calls from residents awakened by the quake. Its epicenter was 11 miles east-southeast of the Los Angeles Civic Center, the USGS reported. It struck at 4:04 a.m.

"First it was a small one and then a big one," said Chris Curiel, who was working at the Vallejo Mini Market in Whittier, a town near the epicenter. "It felt like the floor was sinking."

He said merchandise on the shelves began shaking, but there was no damage. Because his market is a gas station, earthquakes are a bit more worrisome, he said.

Curiel said he knew immediately an earthquake was happening, and he has felt one before.

Ravi Singh, night shift supervisor at a 7-Eleven in Pico Rivera -- the town a mile east-northeast of the epicenter -- told CNN he was making coffee when the store's windows started rattling. There was no damage, he said. "Everything is fine."

iReporter says "it sounded like there were kids dancing upstairs"

Although the temblor was centered 11 miles below the Earth's surface, according to USGS, the movement was enough to awaken some southern Californians.

"It felt like two quick jolts," said CNN's Rosalina Nieves. "I felt some shaking, and I wasn't sure if it was just my upstairs neighbor ... but then you definitely felt two quick jolts." She said the movement lasted for a couple of seconds.
