Being a little overweight may tip the odds in favor of living a long life, according to a new analysis. Researchers say there may be some benefit to having a little extra body fat.
This isn't the first time researchers have raised questions about the link between body weight and how long someone will live. While there's no debate that being severely obese will raise the risk of all kinds of illnesses and even cut some lives short, it's less clear what happens to people who are less overweight.
Most of us do everything possible to avoid mosquitoes. But one Italian researcher literally sacrifices her right arm to keep the lowly insects alive.
Chiara Adolina is studying a new malaria drug, and she needs the little suckers for her experiments. So she feeds them each day with her own blood.
She extends her arm into a mosquito cage to give the insects "breakfast." Several dozen mosquitoes spread across her forearm and jam their proboscises into her skin. "Can you see how fat they become?" she says. "Look at that tummy."
The millions of Americans who make New Year's resolutions to lose weight often have pictures in mind.
They're pictures that have been repeatedly supplied by the health and beauty magazines at supermarket checkout lines. They feature skinny models in bikinis, or toned guys with six-pack abs, and captions about how you could look like this by summer.
Some people go so far as to tape these pictures onto their refrigerators and cupboards. When they're tempted to reach for a cookie, they reason, the sight of that toned model might dissuade them from breaking their resolutions.
For scientists who study a dangerous form of bird flu, 2012 is ending as it began — with uncertainty about what the future holds for their research, but a hope that some contentious issues will soon be resolved.
It's well-known that chemotherapy often comes with side effects like fatigue, hair loss and extreme nausea. What's less well-known is how the cancer treatment affects crucial brain functions, like speech and cognition.
For Yolanda Hunter, a 41-year-old hospice nurse, mother of three and breast cancer patient, these cognitive side effects of chemotherapy were hard to miss.
"I could think of words I wanted to say," Hunter says. "I knew what I wanted to say. ... There was a disconnect from my brain to my mouth."
About a month ago, Declan Procaccini's 10-year-old son woke him early in the morning in a fright.
"He came into my bedroom and said, 'Dad, I had a horrible, horrible dream!' " Procaccini says. "He was really shaken up. I said, 'Tell me about it,' and he told me he'd had a dream that a teenager came into his classroom at his school and shot all the kids in front of him."

The Consumer Products Safety Commission is fed up with the Nap Nanny.
Three models of the infant recliners — Nap Nanny Generations One and Two, and the Chill — are being recalled voluntarily by some of the nation's biggest retailers, including Amazon.com and Buy Buy Baby. Consumers can get refunds or credit toward another purchase.
The consumer agency says the recliners "contain defects in the design, warnings and instructions, which pose a substantial risk of injury and death to infants."

The McDonald's at the Truman Medical Centers' main campus in Kansas City, Mo., has closed, ending an epic, two-decade stint inside the hospital and making it the fifth health facility in the past few years to give the Big Mac the boot.
Katie Alonzo was stunned when doctors told her they couldn't get a drug her 10-year-old daughter, Abby, was taking to fight lymphoma.
"When a doctor says, 'This is what you need to take.' And then all of a sudden somebody tells you, 'Well, that is what you need to take but this isn't available so we're going to try this instead,' it's very scary," say Alonzo, who lives in Port St. Lucie, Fla.
It's been a mixed year for Alzheimer's research. Some promising drugs failed to stop or even slow the disease. But researchers also found reasons to think that treatments can work if they just start sooner.
Scientists who study Alzheimer's say they aren't discouraged by the drug failures. "I actually think it was a phenomenal year for research," says Bill Rebeck, a brain scientist at Georgetown University.
When Sarah Gardner was 34, she started getting really worried about whether she'd ever have kids.
"I bought this kit online that said that they could tell you your ovarian reserve," Gardner, now 40, says. These kits claim they can tell women how long their ovaries will continue producing eggs and how much time they have left to get pregnant.
"Well, mine said, 'we advise really you have a baby now.' Well, sadly that letter arrived three weeks after I just split up with my long-term partner. So, yeah, it opened a massive can of worms really," she says.
When San Francisco prosecutors dismissed charges against Kristian Aspelin in early December, it became just the latest case to raise questions about how shaken baby syndrome is diagnosed. Aspelin, who was accused of causing the death of his infant son, had one thing in his favor: He had enough money to pay for medical experts who cast doubt on the prosecution's theory.
