Can a ‘mosquito magnet’ finally win? Also, why is puberty coming earlier?

Can a ‘mosquito magnet’ finally win? Also, why is puberty coming earlier?

This week, we ask what you can do about mosquitoes this summer, explore health challenges for women in their 40s, discover why walking is the sixth vital sign, and ask how much we really know about this common condition. Plus, what’s up with puberty?


They bite. And bite. Can you beat mosquitos?

These bloodsuckers (shown above) can pick you out in a crowd. Here are the odors they’re drawn to, what scientists recommend to keep them away—and how a future personalized repellent might work.


The decade to take care of challenges

Things crop up for women in their 40s—and can get worse, much worse, if not addressed. On the plus side, this will be the last decade for periods. Hooray, maybe. The 40s are when cardiovascular and cancer risks begin to rise. “It’s an important time for optimizing blood pressure, cholesterol, weight, physical activity—all of that—because frankly, much of this gets harder and more is at stake once you get through menopause,” a cardiologist tells Nat Geo.


Why are fibroids such a mystery?

We’ve known of benign tumors on most older women’s uterine walls for 1,800 years. These solid lumps of muscle (shown above in an x-ray) can grow to the size of a grapefruit, or larger, and could dramatically affect a woman’s quality of life and fertility. But lasting treatments are scarce.

I thought the puberty issue was the elephant in the room no one in the food industry wants to talk about? Since you are what you eat, and animals seem to be getting fed growth hormone in certain countries.... it doesn't take a genius to connect the dots. Several years ago I had a conversation with a couple from the USA about this very topic. They had concerns about their children fast approaching the new age of puberty, so took action to cut out industrially produced meat, and go with organic suppliers who used no growth hormone in their feed. Guess what? Their children went through puberty at a normal age.
