“A fascinating new study is suggesting that a shift in gut bacteria in our middle-age could trigger a process that plays a role in cognitive decline in our later years. And diet may be the key to encouraging the growth of beneficial bacteria that benefit healthy brain aging.” | learn more
Scientists estimate that there are 10x more viruses than bacteria that live in and on our bodies. Just when I thought that bacteria were the most interesting tiny things in the human body… | learn more
“A provocative new study is suggesting the same bacteria responsible for gum disease is also the primary pathogenic cause of Alzheimer’s disease. Not only that, but a new drug developed to inhibit these bacterial toxins and treat Alzheimer’s is moving into major human clinical trials later this year.” | learn more
“Researchers from the University of Chicago, Argonne National Laboratory and the University of Naples Federico II in Italy discovered that when gut microbes from healthy human infants were transplanted into germ-free mice, the animals were protected from an allergic reaction when exposed to cow’s milk.” The upshot: “These bacteria or their metabolites could be used as part of biotherapeutic drugs to prevent or reverse other common food allergies.” | learn more
“Intriguing new research suggests that a particular bacteria may have beneficial anti-inflammatory effects on the brain. Early studies in rodent models found that through injections of the bacteria the animals can be ‘immunized’ against displaying anxious responses to stressful situations.” | learn more

What an eye-opener this book is! Microbes like bacteria and archaea are everywhere. They live on pretty much every species and surface. And, their lives impact ours in myriad complex ways.
Our species has co-evolved with many of the bacteria we live with today. So much so that if we were born in sterile environments, we’d turn out abnormal!
We still know arguably very little about the myriad species of bacteria that live in and among us, but scientists have started realizing their importance and digging in to learn more.
New techniques for DNA sequencing have opened the door to better classification of the microbe species. This book offers a great introduction to the world of microbes. If you’re into health, biology, or science in general – this one is for you.
“As if it’s not bad enough that bacteria are increasingly becoming resistant to our best antibiotics – some bugs are even eating the drugs. An international team of scientists has now examined just how the bacteria disarm and consume the antibiotics as food, uncovering new potential ways to fight back against resistance.” |learn more
“Bonnie Bassler discovered that bacteria “talk” to each other, using a chemical language that lets them coordinate defense and mount attacks.“ This is a TED talk with a transcript available for my fellow readers. | learn more
