Thousands of Unknown Viruses and Bacteria Live in Our Subways

New research out this week confirms that our subways aren’t just jam-packed with people they’re also filled to the brim with viruses, bacteria, and other microbes. Using samples from transit stations in 60 countries, scientists have created a microbial atlas of sorts. But though the scientists have discovered lots of previously unknown species living in these subways, people shouldn’t be too worried about the tiny commuters that they’re spending time around.

The new study is the culmination of a years-long effort by a large team of researchers from all over the globe as part of a project called MetaSUB. Their goal: To map the metagenomics of the world’s major subways and other city environments. Metagenomics is a way for scientists to get a bird’s eye view on the microorganisms that live in a particular environment. To do this, they analyze all of the DNA found in a sample (for example, a cotton swab of a po ....

New pandemic advice from the New York Times: Practicing good hygiene may be worse than COVID-19

New pandemic advice from the New York Times: Practicing good hygiene may be worse than COVID-19
The title of a puzzling opinion piece published recently in the
New York Times, written by author Markham Heid, asks: “Can we learn to live with germs again?” The subtitle proceeds to answer the curious question by suggesting that our health depends on resuming our pre-pandemic “lifestyles that expose us to bacteria, despite the risks” posed by the coronavirus. In short, the entire article promotes, in a virulent form of the not-so-subtle and unscientific construct, “the cure can’t be worse than the disease,” taken to its extreme and bizarre conclusions that good hygiene is worse than COVID-19. ....

The Healthy Gut Microbiome You Have Right Now May Not Be The One You Need in Old Age

The Healthy Gut Microbiome You Have Right Now May Not Be The One You Need in Old Age
21 FEBRUARY 2021
The closer scientists look at the bacteria in the gut, the clearer its importance to our overall health becomes, and new research links a particular type of gut microbiome development with longer lifespans and a healthier old age.

In a study of more than 9,000 people across three different cohorts, new research has found that our gut microbiomes become more unique and personalised to us as we get older, and that the number of core bacteria (such as
Bacteroides) tend to decrease as well. ....

Beyond infection, fungus alters endangered frog's microbiome | University of Hawaiʻi System News

Just as beneficial microbes in the human gut can be affected by antibiotics, diet interventions and other disturbances, the microbiomes of other animals can also be upset. In a rare study, a researcher with the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (
SOEST), determined the skin microbiome of an endangered frog was altered when the frogs were infected by a specific fungus, and it did not recover to its initial state even when the frog was cured of the infection. ....

Researchers Just Looked at Neanderthal Poop to Understand Their Guts

Researchers Just Looked at Neanderthal Poop to Understand Their Guts

Around 50,000 years ago, a bunch of Neanderthals made a home and a bathroom
out of what is now a rocky escarpment south of Valencia, Spain. Over the last few years, some of those paleo-poops, the oldest known to come from a human species, have been excavated and analyzed. Now, researchers have caught a glimpse of the ecosystems that existed in the guts of those early hominins, from a fecal deposit in the remnants of a fire pit on the site.

Over 200 bacterial microorganisms were extracted from the ancient poop by an interdisciplinary team of archaeologists, microbiologists, and anthropologists. The researchers found a striking amount of consistency between the microbial residents of the Neanderthal gut and the sort of microbes that populate the guts of modern humans. That consistency shows many minuscule denizens of our insides are actually longstandi ....
