If your poop contains the kind of microbes that make it suitable for transplants into patients who "need healthy fecal matter in their gut in order to survive," a company called Open Biome wants to buy it from you.
They’ll pay you $40 per sample, plus an extra $50 if you come in 5 days a week (the donations have to be made on-site.) The only thing is, you have to be super-healthy: only about 4% of prospective donors make the cut.
— one of the many "friendly" bacteria that live in our gut — seems to be capable of altering the behavior of mice
, according to a new study. In a mouse model for autism, exposure to Bacteroides fragilis
improved the mice's gastrointestinal function and, along the way, reduced some of their external behavioral symptoms
, including obsessive behaviors and anxiety.
At The Verge, Carrie Arnold writes about a scientist who thinks that our intestinal bacteria could have an influence on mental health
. It's not proven, but it's not a totally crazy idea, either, and there's some good evidence supporting the connection. The catch: Even if what's happening in your gut affects what is happening in your head, there might not be much we can do change the mental health outcomes.
Our great, collective, ongoing realization that wiping out all the bacteria in our bodies may not actually be a great idea marches on. At Scientific American, Deborah Franklin writes about chronic halitosis — the sort of bad breath that doesn't go away with a simple brushing — and scientists' efforts to cure it by encouraging the growth of some mouth bacteria
, instead of pouring Listerine on everything and letting God sort it out.
Here's an interesting project that combines participatory citizen science with crowdsource funding models.
American Gut is a project to catalog, analyze, and compare microbiomes of a diverse swath of Americans. Microbiomes are the bacteria that live in you (and on you). They're both separate from your body and a part of it. Scientists want to better understand what bacteria live with us, what they do, and how the populations of bacteria change depending on factors like your diet, where you live, and your ethnicity. The project is entirely funded by crowdsourcing, so how you participate is also how you donate. For instance, in exchange for a $99 donation, you'll get a kit that will enable scientists to do DNA extraction and 16sRNA sequencing on the bacteria they find in a sample of your skin, saliva, or poop. After they've studied the sample, the researchers will present you with information about your microbiome and how it compares to those of other participants.
You can sign up to donate/participate anytime between now and January 7. There are also a few opportunities available for people who want to participate, but can't donate any money right now.
