Discovered: Everyone thinks they're skinnier than they are, a big Cystic Fibrosis breakthrough, dialysis isn't very sexy and money, not race, explains gap in life expectancy. 

  • Everyone thinks they're skinnier than they are. Such a delusional society we live in. When surveyed most obese people didn't think they had a weight issue, especially men. Among the men, 33.6 percent were overweight or obese, but only 16.9 percent described themselves as such. For women 27.8 percent of women weighed in as  overweight or obese, but only 21.2 percent believed that they were. "This misperception is important because the first step in dealing with a weight problem is knowing that you have one," said researcher Margarita Teran-Garcia. You'll never get skinnier if you already think you're skinny, you dig?

  • A big Cystic Fibrosis breakthrough. Sufferers of the fatal lung disease just got a smidgen of hope, as researchers used stem cells to recreate a part of the lung surface in a petri dish. Just a start,  but it sounds promising. "We're not talking about a cure for CF; we're talking about a drug that hits the major problem in the disease. This is the enabling technology that will allow that to happen in a matter of years," explains researcher Jayaraj Rajagopal. But, of course, "enabling technology" has a bit of a way to go before it turns into "groundbreaking drug." Rajagopal, however, sounds optimistic. "We've created the perfect cell line to show that the drug out there that works against G551D mutation works in this system, and then we're in business to screen for a drug against delta 508," he said. "We'll know soon that the cell line works. We know it makes bonafide airway epithelium, and we'll have the proof of principle that the tissue responds properly to the only known drug. We think this is the near-ideal tissue platform to find a drug for the majority of CF." [Massachusetts General Hospital]
  • Dialysis is not sexy. A big percentage, of women on dialysis experience sexual problems, 84% of all women and 55% of sexually active women, to be exact. As if dialysis wasn't unsexy enough, sigh. That stinks, ladies, sorry. But looks like science is on your side. "With this study, we shed light on the highly frequent condition of female sexual dysfunction in women on dialysis; this deserves attention and further study, since specific interventions are not yet available to address it," explains  Giovanni Strippoli. "Clinicians should not overlook the importance of problems such sexual dysfunction in people who receive hemodialysis for renal replacement therapy," he said.

  • Money, not race, explains gap in life expectancy. Actually it's much more complicated than that, with many factors explaining the difference between races. That chart to the right not only shows how each factor influences the gap, including the combination of certain factors. But, as you can see, income is the number one most influential factor. "My findings are consistent with previous studies in the sense that those tend to conclude that much of the life-expectancy gap between blacks and whites are the result of socioeconomic differences," explains researcher Michael Geruso. "I was surprised, however, that socioeconomic status explains such a large percentage of the gap and that just a few variables are able to account for it," he said. [Demography]
