NewsNewly discovered ‘sixth sense’ links gut microbes to the brain in real time
Researchers have uncovered what they call a “neurobiotic sense,” a newly identified system that lets the brain respond in real time to signals from microbes in our gut. Tiny sensor cells lining the colon’s epithelium detect a microbial protein and send rapid messages to the brain.

NewsRestricted diet triggers individualized microbiome shifts without community convergence
Scientists who carried out a tightly controlled dietary intervention known as the “Oatmeal Study” found that while participants’ diets became nearly identical, their microbiomes did not follow suit.
-
NewsCan a compound produced by deep-sea bacteria treat cancer?
Investigators purified a long-chain sugar molecule, or exopolysaccharide, from deep-sea bacteria and demonstrated that it triggers pyroptosis—an inflammatory form of programmed cell death—to inhibit tumor growth.

NewsStudy discovers that soft drinks affect the communication of gut bacteria and the immune system
Gut bacteria can adapt to environmental changes through DNA inversions. Researchers investigating how these DNA inversions occur found that consuming soft drinks, which contain white sugar, can alter the DNA of gut bacteria and, in turn, impact the host’s immune system.

NewsBacteriostatic activity and mechanism of minerals containing rubidium
A new paper on traditional Chinese medicine outlines the bacteriostatic activity and mechanism of minerals containing rubidium (MCR).

NewsInhaled agricultural dust disrupts gut health
Inhaling agricultural dust may pose significant risks to gut health for workers in animal agriculture, a new study has found. Inhaling hog farm dust alters the gut microbiome and impairs intestinal function, including increased “leaky gut” or intestinal permeability.

NewsFermented stevia leaf extract has potential as anticancer treatment, researchers find
Stevia may provide more benefits than as a zero-calorie sugar substitute. When fermented with bacteria isolated from banana leaves, stevia extract kills off pancreatic cancer cells but doesn’t harm healthy kidney cells, according to a research team.

NewsTumor-targeting fluorescent bacteria illuminate cancer for precision surgery
Researchers have developed a next-generation intraoperative imaging platform using engineered beneficial bacteria that emit fluorescence specifically at tumor sites. This illuminates tumors like a neon sign during surgery, enabling more precise resection and reducing risk of recurrence.

NewsStudy proposes first toxicity-based exposure limits proposed for indoor airborne fungi
A new study provides the first species-specific health risk estimates for indoor airborne microbes based on animal toxicity data. This is the first study to estimate human health risks from indoor microbes using benchmark doses derived from animal toxicity data.
-
NewsControlled human gut colonization by an engineered microbial therapeutic
Engineered gut bacteria designed to treat kidney stones successfully colonized the gut microbiome and reduced oxalate levels in animal models and early clinical trials in humans, researchers report.

NewsBacteria from cows show promising results in treating MRSA infections
Cows carry a bacterium, Staphylococcus simulans, that could become an effective weapon against increased antibiotic resistance. Signaling molecules from this bacterium can treat infections caused by MRSA bacteria as effectively as antibiotics.
-
NewsResearchers develop process to turn food waste into biodegradable plastic
Researchers have developed a process to turn food waste into biodegradable plastic. Their new study offers fundamental findings for any company interested in scaling up the process.

NewsResearchers explore ways to better safeguard romaine supply from E coli outbreaks
E. coli outbreaks in romaine lettuce have long been a public health concern. and now a new paper suggests that a combination of efforts in the field, and even postharvest techniques, can minimize risk to human health.
-
NewsBacterial genomes hold clues for creating personalized probiotics
A new study demonstrates the ability to predict the nutritional adaptations of Bifidobacterium strains by analyzing the distribution of hundreds of metabolic genes in thousands of Bifidobacterium genomes.
-
NewsHow do traditional and biodegradable microplastics affect agricultural ecosystems?
With biodegradable plastics viewed as potential alternatives to traditional plastics in agriculture, researchers investigated the differences in their impacts on agricultural fields and the health of the crop-soil system.

NewsIn hard-to-treat form of tuberculosis, shorter, gentler therapy shows unequal benefit
A first-ever clinical trial exclusively conducted among people with a hard-to-treat form of tuberculosis known as pre-extensively drug-resistant TB shows many patients benefit from shorter, simpler regimens.
-
NewsDisease-causing bacteria can deal with stink as long as they get a meal
Bacteria that cause intestinal infections typically avoid a stinky chemical — one that can kill them at high enough concentrations — inside human intestines, but they may actually swim toward it when a hearty meal is the reward.
-
NewsNitrogen may limit natural climate solutions
A global inventory reveals nitrogen is in shorter supply than previously thought in natural areas, which could limit carbon storage in plants and soils.
-
NewsHidden bacterial redundancy could be antibiotic game-changer
Staphylococcus aureus possesses a surprising level of metabolic redundancy, allowing it to survive even when key enzymes are knocked out, a new study finds. However, when two specific enzymes are removed, staph doesn’t infect its host as readily.

NewsBacteria gene discovery enhances key antibiotic production for farming and medicine
Monensin is a vital antibiotic used in agriculture and medicine. By analyzing the genome of Streptomyces cinnamonensis, the team discovered that specific genes (fadD, fadE, fadB, fadA) in the fatty acid degradation pathway significantly boost monensin synthesis.
