NewsBacteria can make testosterone. What could that mean for prostate cancer?
Scientists have identified an unexpected participant in androgen chemistry: a bacterium from the human urinary tract that can convert the steroid precursor DHEA into testosterone under laboratory conditions. It reveals a previously unknown microbial route to a hormone that is central to prostate biology.

NewsResearchers find C. difficile colonization in infants reshapes gut development
Practically since its discovery, the highly contagious bacterium Clostridioides difficile has been reported to not cause symptoms in infants. But new findings suggest that the bacterium can reshape the developing infant gut and may have long-term consequences.

NewsScientists discover link between gut bacteria and severe liver disease
Researchers have identified what may potentially be a missing link between specific activities in gut bacteria and the liver disease primary sclerosing cholangitis: the metabolite ImP, a molecule formed when certain gut bacteria break down dietary components.

NewsWhat happens when a shoreline scavenger consumes microplastics?
Researchers report on what happens when wharf roaches, a common shoreline scavenger, eat expanded polystyrene (EPS). Analysis of the wharf roach gut microbiome showed little change, but several rare microbes were found only in the EPS-fed specimens.

NewsInternational award supports research into fern-microbe symbiosis
Dr Sophie de Vries will combine evolutionary genomics with experiments that pair ferns and different microbes, to investigate how plants fight off “foes” (diseases) at the same time as supporting their beneficial “friendships” (bacterial partners).

NewsMXene-based hydrogel disrupt bacterial biofilms and reprogram immune cell metabolism to reverse bone resorption in periodontitis
Researchers have developed an injectable MXene-based composite hydrogel (GQM) for the treatment of periodontitis. The hydrogel consists of oxidized gellan gum (OG), quaternized chitosan (QCS), and magnesium-tannic acid modified MXene nanosheets (MTA-Mg).

NewsStudy sheds light on how bacteria assemble outer membrane proteins
Researchers analyzed the various conformations that a chaperone protein adopts while delivering unfolded outer membrane proteins to the assembly machinery.

NewsThe body doesn’t just absorb a plant-based diet—it adapts to one, new review finds
A new review of plant-based diets concludes that the body actively adapts to sustained dietary change, absorbing iron more efficiently, synthesizing more of its own creatine and carnosine, using protein more economically, and remodeling gut bacteria to better ferment fiber.

NewsDifference in clinical characteristics and outcomes between hospital-acquired and community-acquired pleural infection
A critical aspect of managing pleural infection is understanding differences between hospital-acquired and community-acquired forms, as these two entities differ fundamentally in etiology, microbiology, antimicrobial resistance patterns, and patient populations.

NewsMicro-bladder model offers clues to stopping recurrent UTIs
A new study shows that phage therapy – the use of tiny viruses to kill bacteria without harming people – could help to reduce recurrent infections, which happen when the bacteria responsible for UTIs ‘hide’ in the tissue of the bladder.

NewsProbiotic and postbiotic treatments revive heat-stressed corals
Researchers have established that both live probiotic and inactivated postbiotic treatments improve coral health—while the animals are under thermal stress during a natural marine heatwave.
-
NewsPreliminary wastewater bioremediation by photosynthetic Chlorobium genus isolated from pond water
Researchers have isolated naturally occurring light-driven bacteria from local pond water and shown that, within just one week, these microorganisms can substantially reduce the levels of organic pollutants in raw sewage.

NewsAncient Dujiangyan water wisdom inspires AI microfluidic chip to spot hidden sub-resistant bacteria
To pinpoint hidden populations of bacteria, researchers have developed a deep learning-based microfluidic rapid phenotypic AST system, named DP-AST, inspired by the “six-four water diversion” principle of the ancient Dujiangyan irrigation system in China.

NewsIndy gene reduction linked to healthier gut microbiota and longer lifespan in fruit flies
Scientists investigating aging have shown that Indy reduction is associated with lower bacterial load and higher bacterial diversity in aging Indy flies compared to controls.

NewsChina’s 2025 resistance map reveals progress and renewed threats
A 2025 analysis from the China Antimicrobial Surveillance Network (CHINET) tracked 516,309 clinical bacterial isolates from 80 hospitals across China, revealing a mixed picture: resistance declined in some major pathogens, but worrying rebounds appeared in others.

NewsA decade without congenital syphilis: a Danish success story
The basis for this public health landmark: universal screening of pregnant people during the first trimester of pregnancy has been offered free of charge in the country since 2010.

NewsBacterial nanoplatform targets spleen to reprogram immune cells and prevent cancer recurrence
Researchers have announced the development of an engineered nanoplatform named t-SMC, which precisely targets the spleen to reverse splenic myelopoiesis toward an antitumoral immune phenotype.
-
NewsSulfur-reducing mechanism of bacterial selenoprotein discovered
A newly discovered multiheme enzyme in Geobacter sulfurreducens contains selenocysteine, which is encoded by a recoded UGA stop codon in the bacterial genome. This enzyme uses a unique selenium–sulfur–heme catalytic center to reduce polysulfides during elemental sulfur respiration.

NewsUnderground methane leaks may cultivate microbes that help consume them
Researchers have identified where naturally occurring soil microbes consume methane released from underground natural gas leaks. Methane-consuming microbes were most active in a narrow zone near the surface where methane rising from below meets oxygen entering from the atmosphere.

NewsAn enzyme with potential: New type of plastic-degrading enzyme discovered in bacteria
Researchers have identified a new enzyme that can not only degrade certain polyesters and bioplastics, but also might provide bacteria with resistance to antibiotics. The discovery raises hopes that microorganisms can adapt to plastic degradation more rapidly than previously thought.
