Too much of either one may clog your arteries.

New York City Mayor Michael Bloomberg announced in May that the city would launch a campaign through which participating public and private hospitals will take steps to encourage new moms to breastfeed their babies.

The program – with the descriptive if unlovely name “Latch On NYC” – is in the news again because its policies officially go into effect on Sept. 3.

Building on a 2007 initiative in which city hospitals stopped giving promotional “goody bags” filled with baby formula, Latch On will have hospital staff explain breastfeeding’s benefits over formula feeding and make it easier for women to choose nursing.

One of the means of achieving this is to offer formula only to women who request it or when formula feeding is made medically necessary by a mother’s or infant’s health situation.

Most older women with early-stage, estrogen-positive breast cancer may benefit from receiving radiation treatment after lumpectomy, new research finds.

The study, published Monday morning in the journal Cancer, largely contradicts current breast-cancer treatment guidelines, which call for estrogen-blocker drug treatment but not radiation after breast-conserving lumpectomy surgery.

Conducted by researchers at the University of Texas MD Anderson Cancer Center, the new study set out to determine whether older women with early-stage, estrogen-positive breast cancer would have a better chance of avoiding future mastectomy if they were to receive radiation treatment after their lumpectomy.

When men are under stress, they are more likely to find larger women’s bodies attractive.

So says a small study published Wednesday in the journal PLoS One. Researchers at London’s University of Westminster and Newcastle University, both in Britain, assembled 81 white male undergraduates to test a hunch (based on previous studies) that men under psychological stress might prefer bigger-bodied women than men who aren’t stressed might choose.

It’s hard for most of us to imagine what goes through the mind of a hoarder.

But a new study has captured images of exactly what happens inside a hoarder’s mind. The findings could eventually lead to more effective treatments for this disabling disorder. In the meantime, they shed light on the subtleties of a baffling condition.
