Jan Molinell lost $300,000 when Enron collapsed. A former Enron Corp. employee in Florida, Molinell closely followed the trials of Kenneth L.

You don't have to be a sports fan to know that something extraordinary happened in the World Cup soccer final last week. Ten minutes from the climactic end -- with his country's hopes, the championship and his place in the history books at stake -- French captain Zinedine Zidane violently...

You could be forgiven for thinking the television images in the experiment were from 2006. They were really from 1982: Israeli forces were clashing with Arab militants in Lebanon. The world was watching, charges were flying, and the air was thick with grievance, hurt and outrage.

President Bush came to Washington promising to be a uniter, but public opinion polls show that apart from a burst of camaraderie after Sept. 11, 2001, America is more bitterly divided and partisan than ever.

So the bad news is that it is hot and sticky and muggy. Your skin makes tearing sounds when you get up from a plastic chair. On the Metro, you start to tell people apart by how they smell.

Office managers are under siege. They know that if they set the temperature to 74, they hear from the woman in human resources who says it is too cold. If they turn it up to 76, they hear from the man in marketing who wants to know why it is sweltering hot.

Both athletes were stars. Both faltered, then staged dramatic comebacks -- displaying the tenacity that separates heroes from also-rans. Both now face drug charges that could end their careers.

Is Pluto a planet? The world's astronomers met in Prague last week to vote on this question, and in a sort of cosmic game of "Survivor," they voted Pluto off the solar system.
