Cancer-fighter Avastin just came up short as a treatment for ovarian tumors.

Two studies found that the drug, which blocks the formation of new blood vessels, didn't extend the lives of patients with ovarian cancer.

Avastin did slow the progression of the cancers a little bit. But the patients getting Avastin as part of treatment with several medicines had more side effects, including blood clots and high blood pressure, than the people who didn't get it.

Venezuelan President Hugo Chávez mused that the United States might be behind his cancer and that of other leftist leaders in Latin America.

Reuters reports:

"'It would not be strange if they had developed the technology to induce cancer and nobody knew about it until now ... I don't know. I'm just reflecting,' he said in a televised speech to troops at a military base.

The Los Angeles Times writes today that former Libyan leader Moammar Gadhafi's 35-year-old daughter Aisha is "reportedly eyeing asylum in Israel."

Another strong turnout this morning for Mitt Romney at a restaurant in Cedar Falls, though the small place wasn't quite as packed as yesterday's breakfast stop in Muscatine. Romney spent a lot of time shaking hands and posing for pictures with customers, supporters and restaurant staff, after he spoke for about 20 minutes. He usually takes a couple of questions from the crowd but did not today, preferring to spend more time than usual glad-handing.

When I'm considering a gourmet lunch, meatballs don't exactly spring to mind. So I was more than a little surprised to hear that haute cuisine chef Michel Richard was opening a meatball joint just down the street from NPR headquarters in Washington, D.C.

Our post-Christmas post about the estimated $41 billion worth of gift cards that haven't been redeemed since 2005 seemed to strike a chord. And our shout-out for ideas about what to do with cards you don't want or that only have a little bit of money left on them generated some good responses. Such as this:

The lede on an Associated Press report this morning:

"Four-star general-turned-CIA director David Petraeus almost resigned as Afghanistan war commander over President Barack Obama's decision to quickly draw down surge forces, according to a new insider's look at Petraeus' 37-year Army career."

2011 may go down as the year of the retraction in the scientific world.

Among the highly publicized discoveries that got debunked this year: a genetic basis for longevity; a new form of life; an explanation for autism; and a link between a virus and chronic fatigue syndrome.

All of these non-discoveries have something in common. They involved findings that both scientists and the public badly wanted to believe.

At every stop in Iowa, former House speaker Newt Gingrich touts his experience. He calls himself a "supply-side conservative" who worked with Ronald Reagan in the 80's and again as House speaker in the 90's to revive the economy.

But he's not averse to a good photo op.

At The Chocolate Season in Algona Wednesday, owner Erika Jensen showed Gingrich and his wife Calista how to make hand-dipped chocolates.

Working the night shift is bad for your health. But what if that's because the food is so lousy?

That's the provocative question raised this week by the editors of PLoS Medicine, an online medical journal.
