In more than half of early-onset cases, colibactin damage was linked to the mutations.Researchers have linked colibactin to this cancer, but they haven't studied its role in patients under 50. This may help explain why colorectal cancer...

Scientists have discovered a bacterium that can break down toxic "forever chemicals" DepositphotosThe so-called "forever chemicals" (PFAS) are increasingly present in the environment, food, drinking water, and even our bodies. However, researchers may have found a new solution to this problem: a bacterium capable of consuming these compounds and their toxic byproducts.Per- and polyfluoroalkyl substances...

An experimental treatment has shown excellent results in mice with the disease and uses a natural substance produced by beneficial gut bacteria.Understanding VitiligoVitiligo is an autoimmune condition that destroys melanocytes, the cells responsible for producing melanin, the pigment that gives skin its...
Credit: PixabayResearchers at the University of Basel have uncovered how bacteria sense environmental threats using a universal danger signal. When nearby cells are dying, bacteria detect fragments of their cell walls, called peptidoglycans, and proactively form protective biofilms. This discovery sheds light on bacterial communication and defense mechanisms, offering insights for combating infections.Sensing Danger:...
Credit: PixabayKristian Riesbeck, a professor of clinical bacteriology at Lund University, was approached by Ukrainian microbiologist Oleksandr Nazarchuk for help in assessing antibiotic resistance in bacteria from severely injured, infected war patients. Using samples from 141 individuals, including 133 adults and 8 newborns with pneumonia, the study revealed widespread resistance to broad-spectrum antibiotics. Alarmingly,...
The medication fights against carbapenem-resistant Acinetobacter baumannii, a challenging human pathogen that eludes the majority of antibiotics.

The antibiotic, named zosurabalpin, has exhibited promising results in laboratory experiments and...
Researchers have found that the health of the gut microbiome during infancy is key to whether children develop common allergiesDepositphotosA recent study discovered a common factor among four major childhood allergies: an early-life imbalance in gut bacteria. These findings may lead to treatments aiming to restore the gut microbiome in children, potentially averting lifelong...
Lake Gossenköllesee is located in the Tyrolean Alps.

Phototrophic organisms at the bottom of the food chain convert plentiful sunlight into the energy that ultimately powers all other...
RIKEN physicists have created an LED that emits in a narrow region in the far ultraviolet that is safe for humans but deadly for viruses and bacteria. Credit: RIKENRIKEN physicists have engineered an exceptionally efficient LED that is lethal to microorganisms and viruses while being safe for humans. Someday it may help nations overcome...
