Scientists at UC San Diego Want You to Mail Them Your Poop

Poop. It’s fun to say, funny to talk about, and makes for an all-purpose emoji. But who wants to actually handle it?

Now, researchers of the American Gut Project at the University of California, San Diego, may be giving people new motivations to not only retain a stool sample, but pack it up and ship it to them. According to Inside Science, a team led by biologist Rob Knight is currently welcoming fecal samples from the public at large to analyze their microbiome profiles.

The microbiome is the assembly of bacteria, fungi, and other organisms that live in and on our bodies, which can change in response to lifestyle habits like diet and exercise. Recent research suggests that some microbiome profiles may make people predisposed to conditions like obesity and cancer, and might even influence our mental health. Altering the microbiome may have potentially beneficial health effects, which is why researchers like Knight are looking to collect data—in this case, poop.

“Your microbiome weighs about as much as your brain does—you're talking about a couple of pounds of material,” Knight told Inside Science. “And it certainly has more cells, way more genes, arguably as much complexity as your brain. And we're just starting to understand the far-reaching effects that it has on the rest of your body.”

Knight says that over 10,000 people have already donated their excrement for science as part of the project. And it's already producing results. In the first published study of the American Gut Project's work, which appeared in the American Society for Microbiology's journal mSystems in May 2018, the researchers found that plant-heavy diets led to a more diverse bacterial colony in stomachs than people who ate comparatively fewer types of greens. Their data also showed some preliminary evidence that people with mental health complaints tended to have similar microbiomes as people who reported the same issues.

Knight and his colleagues would love to analyze your poop in an effort to compile more information, but there is a catch: Donors have to pay a $99 fee to join the project, an informal kind of crowdfunding that keeps the research financed. If you submit a sample—basically a poop swab taken from your used toilet tissue—the team at Human Gut will send you a personalized microbiome profile and an assessment of how your gut flora compares with the rest of the population. For incrementally larger fees, you might be able to see how your diet, level of exercise, and family members' flora affect your microbiome at finer resolutions. They’ll even test your dog’s donations.

You can join the effort here. The future of poop research thanks you for your participation.

A Massive Beef Recall Due to E. Coli Might Affect Your Memorial Day Meal Plans

If your Memorial Day weekend plans involve grilling meat, you're going to want to take some extra precautions. The U.S. Department of Agriculture announced Wednesday that 62,112 pounds of raw beef are being recalled due to possible contamination with E. coli bacteria, which causes food poisoning.

The meat originated with the Aurora Packing Company of North Aurora, Illinois on April 19. Aurora Packing is recalling the products, which have an EST. 788 number on the USDA mark of inspection found on packaging and were shipped to stores around the country. The meat was packaged in multiple cuts, including ribeye and briskets.

Escherichia coli, better known as E. coli, is bacteria that affects the gastrointestinal system, causing cramps, vomiting, diarrhea, and other serious symptoms that can derail one's celebratory mood. If you think you've purchased any of the contaminated meat, it's recommended that you immediately discard it.

Airports Are Fighting Traveler Germs with Antimicrobial Security Bins

If you plan to do any air travel this summer, chances are you'll be negotiating a path riddled with bacteria. In addition to airport cabins being veritable Petri dishes of germs from the seat trays to the air nozzles, airport security bins are utterly covered in filth thanks to their passage through hundreds of hands daily. These bins are rarely sanitized, meaning that cold, flu, and other germs deposited by passengers are left for you to pick up and transmit to your mouth, nose, or the handle of your carry-on.

Fortunately, some airports are offering a solution. A new type of tray covered in an antimicrobial substance will be rolled out in more than 30 major U.S. airports this summer.

The bins, provided by Florida-based SecurityPoint Media, have an additive applied during the manufacturing process that will inhibit bacterial growth. The protective coating won't wear or fade over time.

Microban International, a company specializing in antimicrobial products, made the bins. According to the company, their antimicrobial protection works by disrupting the cellular function of the microorganism, making it unable to reproduce. As a result, surfaces tend to harbor less of a bacterial load than surfaces not treated with the solution.

While helpful, Microban is careful to note it's no substitute for regular cleaning and that its technology is not intended to stop the spread of disease-causing germs. In other words, while the bins may be cleaner, they're never going to be sterile.

If you're flying out of major airports in Denver, Nashville, or Tampa, you can expect to see the bins shortly. They'll carry the Microban logo. More airports are due to get shipments by early July.
