A stream of highly charged particles from the sun is headed straight toward Earth, threatening to plunge cities around the world into darkness and bring the global economy screeching to a halt. This isn't the premise of the latest doomsday thriller. Massive solar storms have happened before - and another one is likely to occur soon, according to Mike Hapgood, a space weather scientist at the Rutherford Appleton Laboratory near Oxford, England. Much of the planet's electronic equipment, as well as orbiting satellites, have been built to withstand these periodic geomagnetic storms.

What spreads almost as fast as necrotizing fasciitis, a.k.a. flesh-eating infection? News stories about it. Surely by now you've heard about the horrifying case of Aimee Copeland, the 24-year-old Georgia graduate student who cut her leg on May 1 and was on life support by May 4. When Copeland regained consciousness, much of the plugged-in world knew what she still did not: Her left leg had been amputated, skin on her abdomen had been removed and...

The PSA test should be abandoned as a prostate cancer screening tool, a government advisory panel has concluded after determining that the side effects from needless biopsies and treatments hurt many more men than are potentially helped by early detection of cancers. At best, one life will be saved for every 1,000 men screened over a 10-year period, according to the U.S. Preventive Services Task Force. But 100 to 120 men will have suspicious results when there is no cancer, triggering biopsies that can carry complications such as pain, fever, bleeding, infection and hospitalization.

Los Angeles has made slow but significant progress toward ending homelessness, but the City Council is about to vote on a proposed law that could stop that momentum in its tracks. The Community Care Facilities Ordinance would threaten the well-being of thousands of people with disabilities, create a nightmare for property owners, cost taxpayers more, violate principles of fair housing and jeopardize access to federal funds. The proposed ordinance grew out of an effort to eliminate sober-living homes in residential neighborhoods.

Today, a century and a half after Charles Darwin published "On the Origin of Species by Means of Natural Selection," the overwhelming majority of scientists in the United States accept Darwinian evolution as the basis for understanding how life on Earth developed. But although evolutionary theory is often portrayed as antithetical to religion, it has not destroyed the religious faith of the scientific community. According to a survey of members of the American Assn. for the Advancement of Science, conducted by the Pew Research Center in May and June this year, a majority of scientists (51%)

Last week, the Senate voted on a proposal by New Jersey Sen. Robert Menendez to end some of the billions of dollars in handouts enjoyed by the fossil-fuel industry. The Repeal Big Oil Tax Subsidies Act was a curiously skimpy bill that targeted only oil companies, and just the five richest of them at that. Left out were coal and natural gas. Even so, the proposal didn't pass. But that hasn't stopped President Obama from calling for an end to oil subsidies at every stop on his early presidential-campaign-plus-fundraising blitz.

The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis. Everywhere we look, it appears that the world was designed so that we could flourish. The position of the Earth around the sun, the presence of organic materials and water and a warm climate - all make life on our planet possible. Yet, with perhaps 100 billion solar systems in our galaxy alone, with ubiquitous water, carbon and hydrogen, it isn't surprising that these conditions would arise somewhere.

Before John Lennon imagined "living life in peace," he conjured "no heaven … / no hell below us …/ and no religion too. " No religion: What was Lennon summoning? For starters, a world without "divine" messengers, like Osama bin Laden, sparking violence. A world where mistakes, like the avoidable loss of life in Hurricane Katrina, would be rectified rather than chalked up to "God's will. " Where politicians no longer compete to prove who believes more strongly in the irrational and untenable.

The day after Congress passed the new healthcare law, an opponent called it "a fiscal Frankenstein. " In fact, those are fitting words for Roth individual retirement accounts, or IRAs. Roths drive up the federal deficit and cause other pain. They're great for holders but grim for America. It's time to retire them. Retirement accounts were designed by Congress to spur saving by Americans for their golden years. Let's compare a Roth IRA to other accounts, such as traditional IRAs, 401(k)

In ABC's new thriller "Missing," a former CIA agent whose child has been kidnapped springs out of retirement with guns, martial-arts skills and primal parental passion blazing. If that sounds familiar, well, it was also the plot of the 2008 film "Taken," which had Liam Neeson tearing through Paris to extricate his daughter from the clutches of a sex-trafficking ring. In "Missing," the gender roles are reversed. When Michael (Nick Eversman), a student studying abroad in Rome, goes missing, his mother, Becca Winstone (Ashley Judd)

In the year since President Obama approved a successful raid against Osama bin Laden, public opinion has been shifting. While many Westerners still celebrate the targeted killing - along with the killing several months later of Anwar Awlaki - some are expressing doubts. European politicians, human rights lawyers and members of some East Coast think tanks have posited that these terrorists were actually more dangerous dead than alive. Death, the reasoning goes, martyred the leaders, thus immortalizing their ideas and appeal.

Barack Obama and Mitt Romney are both smart and accomplished individuals. That's why it is so disappointing that neither candidate has taken a truly responsible position when it comes to the nation's fiscal future. That's not to say that both men haven't advanced some good ideas. Romney, for example, is pushing to limit federal spending, and he's showing political backbone in putting Social Security and Medicare reforms on the table. But Romney also signed the Americans for Tax Reform pledge to "oppose and veto any and all efforts to increase taxes.

Dolores Huerta runs on righteous ferocity the way cars run on gasoline. The woman who co-founded the United Farm Workers union 50 years ago with Cesar Chavez has harried, prodded, hectored, rallied and protested. She's been arrested more than a score of times, and once, picketing in San Francisco, she was beaten so badly by a police officer that her spleen was ruptured. You'd be hard-pressed to tell, the way she bounces around the Central Valley, a woman on many missions. So, can she stand still next week in Washington long enough for President Obama to present her with the Medal of Freedom, along with honorees such as Toni Morrison, John Glenn and Bob Dylan?

It is a bad outcome - but it is the least bad of the available options. When world powers meet with Iran on Wednesday in Baghdad, they may reach an interim nuclear deal. Its precise outline is unknown, but it reportedly includes Iran's agreement to cease weapons-grade uranium enrichment, ship its existing stockpile abroad for conversion into reactor fuel, and accept heightened inspections of its nuclear infrastructure. In exchange, Iran would be allowed to continue enrichment at low levels, and the punishing new American banking sanctions and European Union oil sanctions due on July 1 would be eased.

The current debate over Mitt Romney's tenure at Bain Capital is shaping up to be a centerpiece of the presidential campaign. The Romney campaign should have seen this coming. If Newt Gingrich and Rick Perry were willing to rip Romney for being too capitalistic in a Republican primary, it doesn't take a lot of imagination to expect that Barack Obama and Joe Biden would happily do the same in the general election. Moreover, if you are going to campaign on the idea that you were a private-sector job creator, it's certainly fair game for your opponents to investigate the claim.

Gloria Romero is a Democrat. She was elected to the California Assembly as a Democrat and later to the state Senate. She served as Democratic leader of the Senate, the first woman to do so. Ben Austin is a Democrat too. He worked in the White House under President Clinton and was an ardent supporter of Barack Obama. Both Austin and Romero support reform of the nation's education system, and when Romero helped found an organization to push that effort, she and her co-founders (fellow Democrats)

The Roman Catholic Church has either a very good or a very bad sense of humor. The Vatican has announced that the late Pope John Paul II will be beatified on May 1. Beatification, which requires church certification of a miracle by the would-be saint, is sort of a halfway house on the way to full sainthood, which takes two miracles. JP2's beatification, if it proceeds as scheduled, will have been the fastest on record ? six years, from death to finish, edging out the previous record holder, Mother Teresa, by just a few days.

As the World Health Assembly convenes in Geneva this week, one item on the agenda will be polio, or more specifically, how to finally deliver on an epic promise made a quarter-century ago: to liberate humankind from one of the world's most deadly and debilitating diseases. The world's war on polio has been as ambitious an undertaking as the successful campaign to eradicate another great public health menace, smallpox. Slowly but surely we have advanced on that goal. Polio, a highly preventable disease, today survives in only three countries: Afghanistan, Nigeria and Pakistan.

Political advocacy corrupts academic institutions. Why? Because the mind-set of a genuine academic teacher is in every important respect the opposite of a political activist's. Academic teachers want to promote independent thought and analytical skills; political activists want conformity. The one fosters intellectual curiosity and encourages opposing viewpoints; the latter seeks to shut it down. This vital distinction is well understood. In California, the state Constitution contains this unambiguous statement: "The university shall be entirely independent of all political or sectarian influence and kept free therefrom.
