NewsMore investigations needed into Wumei Pills-Lactobacillus Reuteri-intestinal stem cell axis for chemotherapy-Induced mucositis
A new letter appraising a recent study suggests the reported benefits of WMP and Lactobacillus reuteri in chemotherapy-induced mucositis are promising, but stronger causal and analytical foundations are needed.

NewsBiologists and engineers follow goopy clues to plant-wilting bacteria
Slippery, drippy goop makes Ralstonia bacteria devastating killers of plants, causing rapid wilting in tomato, potato and a wide range of other crops, according to new research.

NewsAncient DNA pushes back record of treponemal disease-causing bacteria by 3,000 years
Scientists have recovered a genome of Treponema pallidum from 5,500-year-old human remains in Sabana de Bogotá, Colombia. The research expands knowledge about the history of this infectious disease and its occurrence in human populations.

NewsResurrected ancient enzyme offers new window into early Earth and the search for life beyond it
By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers have created a new way to improve our understanding of the origins of life on Earth. The study uses synthetic biology to reverse-engineer modern enzymes and rebuild their possible ancestors.

News‘Trojan horse’ may deliver toxic dose of copper to bacterial colonies, including drug-resistant MRSA infections
A research team is developing a drug that works in combination with copper to kill bacteria, including those that cause MRSA, a type of staph infection that is resistant to usual treatments.

NewsHow a single gene shapes gut health and IBD risk
Two recent studies highlight the role of a gene called PTPN2 in protecting the gut from harmful bacteria linked to inflammatory bowel disease (IBD). When PTPN2 does not function properly, the gut becomes more vulnerable to infection and inflammation.

NewsMethane eating microbes turn a powerful greenhouse gas into green plastics, feed, and fuel
Methane eating microbes could help turn a powerful greenhouse gas into everyday products like animal feed, green plastics, and cleaner fuels, according to a new scientific review of fast moving research on these unusual bacteria.

NewsSecret of youth: New study shows gut microbiota directly regulates intestinal stem cell aging
A new study reveals that age-related changes in the gut microbiota directly impair intestinal stem cell (ISC) function and that restoring a youthful microbial environment can reverse this decline.

NewsScientists synthesize medicarpin in baker’s yeast
Scientists have developed a way to synthesize medicarpin in yeast. Like palitaxel in the 1990s, this tumor-attacking sustance has only limited natural quantitites and is considered difficult to synthesize.

NewsPIXL Max: Automated colony picker breaks records for speed and accuracy
With the latest innovation from the team at Singer Instruments, a new standard for speed and repeatability in microbial colony pickers has been achieved through the integration of cutting edge AI technologies.

NewsChemotherapy rewires gut bacteria to curb metastasis
Researchers report that chemotherapy-induced damage to the intestinal lining alters nutrient availability for gut bacteria, reshaping the microbiota and increasing the production of indole-3-propionic acid (IPA), a tryptophan-derived microbial metabolite.
-
NewsBacteria use wrapping flagella to tunnel through microscopic passages
A new study shows that certain symbiotic bacteria wrap their rotating flagella around their cell bodies to form a “screw thread.” This configuration lets them propel forward through one-micrometer-wide passages, such as those inside insect guts, that would otherwise trap or immobilize them.

NewsSniffing out the cause of keratoderma-associated foot odor
The distinct foot odor that comes with the skin disorder Nagashima-type palmoplantar keratosis (NPPK) is caused by the overgrowth of a specific bacterial strain. Topical application of benzoyl peroxide restores balance in the bacterial skin flora, reducing the odor.

NewsOral bacterium may promote breast cancer development and spread
Researchers found that Fusobacterium nucleatum, an oral bacterium commonly associated with periodontal disease, can promote breast cancer initiation, tumor growth and spread by inducing DNA damage and altering cancer cell behavior.

NewsResearch team identifies species of brucellosis-causing bacteria in Cameroon
Researchers have identified the specific species of the Brucella bacterium that causes illness in animals in Cameroon. A study of more than 4,600 livestock animals found that the only Brucella species present was Brucella abortus, a species primarily associated with cattle that causes pregnancy loss and infertility.

NewsGrowing together, bacterium after bacterium
Social interaction among babies in their first year of life influences and enriches the diversity of their gut microbial strains, based on the findings of a study on microbiome transmission.
-
NewsScientists engineer quantum-enabled proteins, opening a new frontier in biotechnology
A new study reports the creation of a new class of biomolecules, magneto-sensitive fluorescent proteins, that can interact with magnetic fields and radio waves. This is enabled by quantum mechanical interactions within the protein, and occur when it is exposed to light of an appropriate wavelength.

NewsEarly translational study supports the role of high-dose inhaled nitric oxide as a potential antimicrobial therapy
Researchers report that high-dose inhaled nitric oxide (iNO) demonstrates potential antimicrobial activity in preclinical models and is safe and feasible in early human studies, supporting further clinical investigation.
-
NewsNew study shows how light suppresses virulence in antibiotic-resistant pathogen
Researchers uncover a light-sensitive signaling cascade in Pseudomonas aeruginosa that suppresses biofilm formation and virulence, offering a potential new strategy to combat antibiotic-resistant infections.
