question: (CNN) -- It began as horseplay, with two teenage stepbrothers chasing each other with blow guns and darts. But it soon escalated when one of the boys grabbed a knife.

Michael Barton, Quantel Lotts' stepbrother, was stabbed to death at age 17.

The older teen, Michael Barton, 17, was dead by the time he reached the hospital, stabbed twice.The younger boy, Quantel Lotts, 14, would eventually become one of Missouri's youngest lifers.

Lotts was sentenced in Missouri's St. Francois County Circuit Court in 2002 to life in prison without parole for first-degree murder in his stepbrother's stabbing death.

It made no difference that at the time of the deadly scuffle, Lotts was barely old enough to watch PG-13 movie and too young to drive, vote or buy beer.

"They locked me up and threw away the keys," Lotts, now 23, said from prison. "They took away all hope for the future."

His stepmother, the victim's mother, has forgiven Lotts and is working with lawyers to gain his release.

Lotts is one of at least 73 U.S. inmates -- most of them minorities -- who were sentenced to spend the rest of their lives in prison for crimes committed when they were 13 or 14, according to the Equal Justice Initiative, a nonprofit organization in Alabama that defends indigent defendants and prisoners.

The 73 are just a fraction of the more than 2,000 offenders serving life sentences for crimes they committed as minors under the age of 18.

Across the country, most juvenile offenders and many adults are given a second chance. Charles Manson, convicted in seven notorious murders committed when he was 27, will be eligible for his 12th parole hearing in 2012. He's been denied parole 11 times. Even "Son of Sam" killer David Berkowitz, who confessed to killing six people in the 1970s when he was in his 20s, has had four parole hearings, though he has said he doesn't deserve parole and doesn't want it.

question: When the board has no embedded components it is more correctly called a printed wiring board (PWB) or etched wiring board. However, the term printed wiring board has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). The IPC preferred term for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies. The term PCB is used informally both for bare and assembled boards.

Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. Rub-on dry transfers of common component footprints increased efficiency. Traces were made with self-adhesive tape. Pre-printed non-reproducing grids on the mylar assisted in layout. To fabricate the board, the finished photomask was photolithographically reproduced onto a photoresist coating on the blank copper-clad boards.

question: During the years after the terrorist attack on the World Trade Center, structural engineers have been trying hard to solve a question that would otherwise have been completely unthinkable: Can building be designed to stand catastrophic blasts by terrorists?

Soon after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) traveled to ground zero as part of a project funded by the National Science Foundation. They spent two days beginning the task of formulating ideas about how to design such structures and to search for clues on how to do so in buildings that were damaged, but still are standing.

"Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage," said M. Bruneau, Ph.D. "Our immediate hope is that we can develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks," he added.

Photographs taken by the investigators demonstrate the monumental damage to the World Trade Center towers and buildings nearby. One building a block away from the towers remains standing, but was badly damaged. "This building is many meters away from the World Trade Center and yet we see a column there that used to be part of that building," explained A. Whittaker, Ph.D. "The column became a missile that shot across the road, through the window and through the floor."

The visit to the area also brought some surprises, according to the engineers. For example, the floor framing system in one of the buildings was quite strong , allowing floors that were pierced by tons of falling debris to survive. "Good framing systems may provide a simple, but reliable strategy for blast resistance," he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails. "We also need a better understanding of the mechanism of collapse," said A. Whittaker. "We need to find out what causes a building to collapse and how you can predict it."

A. Reinhorn, Ph.D. noted that "earthquake shaking has led to the collapse of buildings in the past. Solutions developed for earthquake-resistant design may apply to blast engineering and terrorist-resistant design. Part of our mission now is to transfer these solutions and to develop new ones where none exist at present."
