Smartphones Are Great for Sharing Bacteria

Smartphones’ proximity to people’s ears, nose and mouth make them a good vector for transferring microbes. Bacteria and other infectious agents on smartphones can cause the flu, pinkeye, or diarrhea. Lab tests show that most phones have abnormally high levels of coliforms, a bacteria stemming from fecal contamination.

In the Rocky Mountains, the South Platte River system flows east through the Coloradan plateau that has plenty cattle ranches, sheep pastures, dairy farms, and water treatment plants. A new survey shows how human activities have affected the concentrations of antibiotic-resistant genes in the watershed.

Number of Microbes Living on Earth Drastically Lower Than Previously Thought

The floor of the ocean is home to 2.9×1029 single-celled organisms but this large number, 10 million trillion microbes for every human on planet Earth, is only 8% of the previous estimate of  35.5×1029. Jens Kallmeyer, a geomicrobiologist and his colleagues at the University of Potsdam in Germany have created the most accurate model of the geographical distribution of microbes in the marine sediment. They published their findings in the journal Proceedings of the National Academy of Sciences.

The microbiota in pregnant women’s gut change as their pregnancy advances, resembling more like those of people who might develop diabetes. These changes, while not damaging maternal health, correspond with increases in blood glucose and fat deposits thought to help the nourishment of the developing child.

CamelBak All Clear UV Water Purifier: Zaps Microbes Dead!

When you’re outdoors, either for camping or because the Great Zombie Apocalypse has finally begun, you need to drink clean water. As such, some of the portable filters and water purifiers are a bit annoying to use, which is why I think that CamelBak’s All Clear UV water purifier is so cool. You just fill up your water bottle and use the integrated UV light, and presto, your water is read to drink.

Researchers May Be Able to Sequence Genomes of Any Microbes

euryarchaeota-methanogen

Until now, researchers could only sequence the genomes of microbes in two ways. They could sequence it directly, which requires growing the organism in a culture to a manageable level, which isn’t always possible, or they could use metagenomics and try and pick out the DNA that belongs to the microbe from the vast amount of genetic material present in an environmental sample. This method only works if the organism is the dominant member of a community. Now, researchers have discovered that with the right computational tools, they can extract individual genomes from the slurry of genetic material in samples, even if the organism hasn’t been grown in a culture.
