Microbiome Awareness Month! The 5-Second Rule?

During this month of frantic, frenzied days, as you are running out the door, noshing on something, what if your snack falls on the floor?  

You’ve probably come across the “Five-Second Rule,” a kind of working hypothesis that supposedly tells you whether it’s safe to eat an item of food you’ve dropped on the floor.  This rule was the subject of a rigorous study conducted by Rutgers University in New Jersey, published in the American Society for Microbiology journal.

The Rutgers researchers meticulously dropped watermelon, bread (buttered and unbuttered), and gummy candy, from a height of 5 inches onto four different surfaces that had been disinfected, inoculated with Enterobacter aerogenes, then allowed to dry.

Watermelon picked up the most contaminating bacteria, while the gummy candy acquired the least.

So, while this month is a busy one, remember that foregoing the 5-second rule and taking time to find something less bacteria-laden to eat may be the best time-saver for your health in the long run.

Microbiome Awareness Month! Nails – Bacteria Havens under Your Nails?

Getting your nails done? Read on…

Regardless of how much you might wash your hands, there are always bacteria present on the surface of your palm, which is known as the stratum cornea. Basically this is your good guys fighting off the bad ones.
The Center for Disease Control and Prevention reminds us, of course, just how important it is to keep hands clean. It says good hygiene can prevent about 30% of diarrhea-related illnesses, and around 20% of respiratory infections (colds, for example).

Besides the skin surface of your hands, there are ten other places on your hands in which bacteria can really flourish: under your fingernails. There can be a ton of microbes lurking in the space under your nails.

In 1989 a group at the VA Medical Center in Sioux Falls, South Dakota looked into bacteria beneath artificial nails, finding that nurses wearing them had considerably more bacteria beneath them than were found under natural nails.
Their recommendation? Short, clean nails are better, even if the salon industry might disagree.

Do Bacteria Say Cheese When They Have Their Photo Taken?

Microbial photography. It’s a thing.

Right now, there’s a good chance that you have a sophisticated digital camera in your pocket, in the shape of a smartphone.

There’s also a high likelihood that it has a lens on both its front and back surfaces, enabling that extraordinary 21st-century technological breakthrough, the selfie.

We’re not sure how they worked it out, but it was estimated that as of December last year, there were 282 million selfies on Instagram.

It’s certainly come a long way since 1826 (or perhaps 1827) when the Frenchman Joseph Nicéphore Niépce took what is now the earliest surviving photograph made in a camera.

It wasn’t a selfie, of course, but the view from his window in the Burgundy region of France recorded on a piece of polished pewter coated with a type of bitumen, and apparently requiring an exposure of several days.

Not very practical for that duck face thing, then.

It took a while, but photography slowly – then rapidly – evolved, using a wide range of techniques that all basically boiled down to chemicals changing color in the presence of light.

However, maybe you’re thinking along the same lines as us: if chemicals can do this, what about bacteria? Continue reading “Do Bacteria Say Cheese When They Have Their Photo Taken?”

The Bowel-Loosening Properties of, Uh, Bookstores

Bookstores and their bathrooms.

One of the most delightful aspects of writing these weekly newsletters is the tips we receive from readers and other members of the uBiome team.

Sometimes they take us to the most unexpected places, but today’s tip must surely rank at the very top of unexpected place-ness. Continue reading “The Bowel-Loosening Properties of, Uh, Bookstores”

Labor Day, Lactobacillus, and Workers in Leather

Let’s hear it for everyone in bacterial businesses.

On Monday, the United States will pay tribute to American workers by giving many the day off. Labor Day is always the first Monday in September, and this year it falls on September 3rd.

Just as you might expect, we at uBiome naturally take our hats off to the American workforce, of which we’re proud to be a part.

And also, just as you might expect, we’re particularly keen to take our hats off to those American workers who work with bacteria, one way or another. Continue reading “Labor Day, Lactobacillus, and Workers in Leather”

After the Eclipse Is Over: Microbes and, Uh, Sun-Powered Laundry Drying

Bacterial life on the 3rd rock from the sun.

Imagine for a moment that the sun was the size of a yoga ball.

The moon would then be roughly the same diameter as the tiny sphere on the end of a sewing pin.

In spite of this 400:1 size differential, for a few minutes yesterday, our friendly local star and our one and only moon appeared to be precisely the same size in the sky, allowing one to cover the other almost exactly.

Here in San Francisco, those who ventured onto the roof of our building were rewarded with – rather than the total solar eclipse that was experienced in a band across the United States – a banana in the sky. Continue reading “After the Eclipse Is Over: Microbes and, Uh, Sun-Powered Laundry Drying”
