The Fukushima crisis is eroding years of Japanese efforts to reduce greenhouse gas emissions blamed for global warming, as power plants running on oil and natural gas fill the electricity gap left by now-shuttered nuclear reactors.

Before last year's devastating tsunami triggered meltdowns at the Fukushima Dai-ichi plant, Japan had planned to meet its carbon emissions reduction targets on the assumption that it would rely on nuclear power, long considered a steady, low-emissions source of energy.

Crab fisherman Mark Anello noticed something odd near his boat off the Northern California coast: three buoys floating nearby were moving. Motoring closer he saw a gray whale tangled in a large fishing line.

It was the same whale, officials determined later, that was first spotted hundreds of miles south off the Orange County coast April 17, dragging several buoys attached to a net.

Kim Kardashian's attorney told a judge Friday that the reality star wants her divorce from Kris Humphries to move forward but that the case has been slowed by the NBA player's hurt feelings and his desire for an annulment.

The couple was married last summer in a lavish, star-studded and televised ceremony, but Kardashian filed for divorce on Oct. 31. Humphries responded a month later asking for an annulment, claiming the couple's nuptials were based on a fraud, but not laying out specific evidence.

Stress, family medical history or possibly even poison led to the death of Vladimir Lenin, contradicting a popular theory that a sexually transmitted disease debilitated the former Soviet Union leader, a UCLA neurologist said Friday.

Dr. Harry Vinters and Russian historian Lev Lurie reviewed Lenin's records Friday for an annual University of Maryland School of Medicine conference that examines the death of famous figures.

Men rarely get breast cancer, but those who do often don't survive as long as women, largely because they don't even realize they can get it and are slow to recognize the warning signs, researchers say.

On average, women with breast cancer lived two years longer than men in the biggest study yet of the disease in males.

The opposition Syrian National Council called on U.N. observers on Saturday to visit the Damascus neighborhoods of Kfar Sousa and Tadamon where nine people died during demonstrations and funerals a day earlier.

In a statement, the SNC urged the observers to visit "where the funerals of the martyrs killed Friday will be held."

London's comic and outspoken mayor Boris Johnson won re-election Friday, triumphing in a closer-than-expected vote to secure a second term and his status as the unvarnished and unpredictable host of the 2012 Olympics

Johnson's victory, in election results confirmed late Friday, was a bright spot on a rough day for his colleagues in Prime Minister David Cameron's governing Conservative Party, who took a drubbing in local elections.

Air France-KLM posted a net loss of €368 million ($483 million) in the first quarter of the year, saying Friday that high fuel costs and a continued drop in cargo cut into its profits.

The Franco-Dutch airline said revenue grew 6 percent to €5.6 billion, but that was not enough to offset the continued slide in the income column. The group made a net loss of €367 million in the first quarter of last year.

Venus Williams thinks it's a fashion statement. A Canadian player describes it as "Smurf clay." Rafael Nadal calls it a mistake.

The Madrid Open is receiving extra attention this year as the Masters Series event for men and women will be the first top-level tournament played on blue clay instead of the traditional red surface.

More U.S. teenagers are postponing sex than in 1995, and hormonal contraceptive use is up among those who are sexually active, said U.S. health authorities on Thursday.
