“Nobody knows exactly how many people there are with it in the United States,” says Nash, who is the chief of the Gastrointestinal Parasites Section at NIH. His best estimate is 1,500 to 2,000.

Worldwide, the numbers are vastly higher, though estimates on a global scale are even harder to make because neurocysticercosis is most common in poor places that lack good public-health systems.

Sometimes scientists tell you stuff you'd rather not hear, you know? For example, if a meteor was going to hit Earth tomorrow and end all life and nothing could be done about it, would you want the scientists to tell you? Maybe that is why [...]

Here is a wonderful email from reader Michelle Siobhan Reid:

I feel tacky writing in and being like, "Post about this!" because I am sure you are inundated with these requests all the time, but there's no harm, I suppose!

Organ donation awareness week is the last week of April for Canada & the US, and while it seems like every day is marked for awareness of something or other, my mom is alive thanks to a transplant in 2009 so I'm pretty into this one. Most people agree that they would like to be organ donors after they die, but they don't register (you are doing better in the [...]

"Doctors have been trained to believe that urine is germ-free. However, these findings challenge this notion, so this research may have positive implications for how we treat patients with urinary tract conditions in the future." —You're in trouble now, Julie?

"Women are having issues as well." —Loss of "genital sensation" is reason No. 9,359 to not bicycle anywhere, or even in place. Here's a friendly explanation, and here's the more-scientific one. Glad that's settled once and for all, eternaly, never to be reexamined.

(Plus, reason No. 9,360.)

“If you have HPV, it’s probably not going to mean anything. It doesn’t mean you’re going to get cancer. As long as you get your follow-up tests, cervical cancer is the most preventable cancer.” —If the third episode of 'Girls' threw you for an HPV loop (why did she get tested, why does she call it precancer, why does that guy say he tested negative, etc.), the Times Well blog parses it all out. Plus there's our handy-dandy Guide to Your Abnormal Pap Smear that has the pictures of cervixes in bowties. Hellooo!

"Breast cancer is not one disease, but 10 different diseases … Our results will pave the way for doctors in the future to diagnose the type of breast cancer a woman has, the types of drugs that will work and those that won't, in a much more precise way than is currently possible." —A new study in Nature that's explained (without a paywall) by the BBC will apparently provide "a completely new way of looking at breast cancer."

"Where do you think children ages 12 to 16 years get most of their daily physical activity? Sports? Gym class? At home? The answer turns out to be largely dependent on where they live. In a study led by Daniel Rainham, of the Environmental Science Program at Dalhousie University, researchers tracked 380 adolescents for a week, using both accelerometers and GPS. They found that teens who lived in rural areas did, in fact, get most of their recommended one-hour daily moderate-to-vigorous physical activity at school. However, kids who lived in suburban and urban environments logged most of their active time getting from place to place. And both groups got [...]

Get screened, find out you're gonna die, stop exercising. But don't sit! Sitting will kill you. Buy one of those sensory-deprivation chambers and just lie there suspended in warm liquid while ingesting fish oil every hour on the hour.

(Thanks for nothing, Ask Men)

1. You are a Ribwich.

2. You donated them to Robert Pattinson for New Moon.

3. The villain from Saw imprisoned you in a room made entirely of white carbs.

4. You mistakenly purchased Women's Health instead, which only told you how to "flatten your belly." Spoiler: it's not anything you're already doing.

5. You need to maintain 30% body fat in order to provide warmth to Cockney matchstick girls.

We'll pick up where we left off: "That shell contains not a bomb but a gift." Or, eat those eggs you hard-boiled this weekend and wrote your coworkers' names on, because they're good for you, as you know.
