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).

NewsInternational Society of Microbiota, Nature Awards and Yakult join forces to connect global funding with Japanese microbiome research
A new collaboration at ISM–RIKEN Targeting Microbiota 2026 will bring the Global Grants for Gut Health programme to Tokyo, alongside a dedicated funding discussion and three Best Abstract Prizes.

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.

NewsArchaea as “flexitarians”: Ammonia-oxidizing microbes also feed on amino acids
Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists, but true “flexitarians”. Research has shown that these microbes dine not only on ammonia but also on amino acids - and presumably do that to communicate with their animal host.

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.

NewsVaricella zoster virus can cause serious disease beyond chickenpox and shingles
New research is shedding light on the surprisingly broad range of neurological and systemic diseases that can be caused by varicella zoster virus (VZV), the virus that causes chickenpox and shingles.

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.

NewsThe push to understand and treat HPV
Karl Munger is helping to lead an effort at Tufts University and Tufts Medicine that brings research scientists together with clinicians to save lives through improved HPV care and research.

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.

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.

NewsHow stressed cells put the brakes on protein shipping
A study in budding yeast suggests that changes in membrane lipids trigger a braking system that slows internal protein transport when the endoplasmic reticulum comes under stress.

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.

NewsCancer medication helps reduce SIV reservoir, increases hope for HIV cure
Researchers have provided the first proof-of-concept in a nonhuman primate model for eliminating HIV-infected cells with venetoclax, a clinically approved medication for cancer.

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.

NewsERC Starting Grant for Tom Beneke: Drug resistance in tropical parasites
Molecular biologist Dr Tom Beneke (35) from the Biozentrum at the University of Würzburg has been awarded a €1.5 million ERC grant to further advance his research on Leishmania and the disease they cause.

NewsInvasive mosquito species detected in east London
The UK Health Security Agency (UKHSA) is undertaking enhanced surveillance and trapping activities following the detection of invasive Aedes aegypti mosquitoes and larvae at nearby residential properties in east London.
