The human immune system relies on DNA rearrangements to fight disease. But it's a two edged sword and it can go wrong...

For years, scientists have noticed an interesting pattern of cancer among children. Those who went to day care early in life were less likely to later develop the most common childhood cancer: acute lymphoblastic leukemia (ALL). Now, a 7-year study appears to have unraveled the molecular mechanism driving ALL. The work may explain why early exposure to infections in places such as day cares seems to protect against the disease and why unrelated vaccines help guard against this cancer...
