Metagenomic Study Reveals the Most Ancient Dairy Remains Known to Date

The oldest method of producing food with microorganisms in human history is food fermentation. Cheese production and consumption dates back to 7000 before the present (BP) among Mediterranean populations, and milk fermentation, for instance, dates back to 6000–4000 BC in India.

Probiotic Bacteria may Help Maintain Brain Function in Aging Nematodes

A group from Nagoya University in Japan has discovered that when the diet of nematodes, tiny worms measuring about a millimeter or less in length, includes the bacteria Lactobacillus reuteri, the weakening of associative learning ability caused by aging does not occur.

Changes in Gut Microbiomes of Astronauts May be Linked to Bone Loss

In space, the bone density of both the human astronauts and rodent variety decreases. Scientists published this study on April 19th, 2023, in the journal Cell Reports. It says that alterations to the gut microbiomes of space travelers may be linked to this bone loss.

Using better probiotics to maintain a healthy gut microbiome

Bacteria have thousands of genes and functions that we, the human host, do not have. For instance, bacteria can help us digest fiber, provide support to our immune systems, and absorb important nutrients. But reaping the benefits of "good bacteria" is easier said than done.

T cell-driven changes in the gut may affect brain function associated with depression

In experiments with mice and humans, a team led by Johns Hopkins Medicine researchers says it has identified a particular intestinal immune cell that impacts the gut microbiome, which in turn may affect brain functions linked to stress-induced disorders such as depression.

Rice biologists embark on a three-year project to create genetically encoded antibiotics

Synthetic biologists at Rice University are embarking on a three-year project to create "genetically encoded antibiotics," strands of RNA that bacteria will readily copy and share that will selectively kill only disease-causing, pathogenic bacteria.

Bile salt hydrolase cocktails may offer a new approach to inhibit C. diff colonization

Not all probiotics are created equal. In a new study, researchers found that certain enzymes within a class known as bile salt hydrolases (BSHs) can restrict Clostridioides difficile (C. diff.) colonization by both altering existing bile acids and by creating a new class of bile acids within the gut's microbial environment.
