NewsHas life-saving HIV therapy contributed to increased rates of a sexually transmitted disease?
A study has uncovered an unintended consequence of a major medical breakthrough: while the availability of HIV treatments in the late 1990s dramatically improved survival, they also contributed to a resurgence in syphilis, a sexually transmitted infection.

NewsScientists probe how neurons sense bacteria in the gut
Neural interaction with bacteria, e.g. in the gut microbiome, has important effects on brains of animals from worms to people. A new study investigates how neurons sense bacteria by revealing, in nematodes, the bacterial signals that a key neuron detects.

NewsNew biosensor for detecting active tuberculosis
A research team is developing a sensor that paves the way for the rapid, selective and cost-effective detection of active tuberculosis. The device detects the presence of a protein secreted by Mycobacterium tuberculosis, the bacterium that causes the disease.

NewsGut bacteria predict skin cancer recurrence, but only when matched for ‘microbial fingerprint’
The specific mix of bacteria living in a person’s gut can predict the chances that melanoma will recur after surgery and immunotherapy, which helps immune cells target cancer cells, according to a new study.

NewsEngineered dual-bacterial sensors turn chemical signals into electricity
Most bacterial information transmission is done via electricity. While electricity-emitting bacteria exist, manipulating them into useful sensors has been quite challenging. Researchers recently developed a flexible bioelectrical sensor system called electroactive co-culture sensing system.

NewsHow tiny cave shrimps grazing on microbes power the underworld of the Yucatan
Because they convert microbial growth in sinkholes beneath the Yucatan Peninsula into animal biomass, Typhlatya shrimps act as “keystone species”, introducing essential nutrients into the cave’s food web. They serve as a crucial initial link that larger subterranean predators feed on.

NewsAntibiotic resistance genes found in newborns within hours of birth, study shows
Antibiotic resistance genes can be present in newborns within the first hours of life. The study analysed meconium samples from 105 infants admitted to a neonatal intensive care unit (NICU) within the first 72 hours of life between July 2024 and July 2025.

NewsCyanobacteria surprise scientists with evolutionary shift
Researchers report a surprising new discovery—a system thought to separate DNA has developed to sculpt the shape of the cell in cyanobacteria instead. The results shed light on how protein systems evolve and how multicellularity emerged in this type of ecologically essential bacteria.

News To thwart pathogens, researchers are giving beneficial microbes what they really want
Researchers have developed a new method that allows precise modification of any microbiome with prebiotics, helping beneficial organisms outcompete dangerous pathogens.

NewsResearchers uncover a ‘treasure trove’ of bioactive molecules in coral reefs
Researchers have found that coral reefs are home to a vast array of previously unknown bioactive metabolites — small biomolecules that have the biotechnological potential to provide the basis for new drugs, and a host of other products.

NewsGraphitized biochar rewires soil microbes to accelerate pollutant breakdown in rice paddies
A new study reveals that a specially engineered form of biochar can dramatically enhance the natural ability of soil microbes to break down pollutants in rice paddies, offering a promising strategy for cleaner and more sustainable agriculture.

NewsStandard-dose antibiotic the ‘preferred choice’ of treatment for uncomplicated acute sinusitis
A study of patients with acute sinusitis found no major differences in measured outcomes between adults who received standard amoxicillin and amoxicillin‑clavulanate. Patients treated with amoxicillin‑clavulanate were at slightly higher risk of contracting secondary infections.

NewsStudy finds blood pressure drug effective for treating antibiotic-resistant bacteria
A new study reports that a drug used to lower blood pressure could also be the basis of a promising new treatment for methicillin-resistant Staphylococcus aureus (MRSA). Candesartan cilexetil not only killed MRSA bacteria at different growth stages, but also reduced the formation of biofilms.

NewsLong-term cure rates for multidrug-resistant tuberculosis much better than expected
A new national cohort study from Latvia provides important insights into the treatment of multidrug-resistant tuberculosis (MDR-TB). The study shows that long-term disease-free survival rates are significantly higher than previous standard indicators suggest.

NewsAncient viruses serving as gene delivery couriers to help bacteria resist antibiotics
Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR).

NewsDon’t build the engine, grow it: biohybrid miniature robots using living organisms
By fusing living organisms like bacteria, algae, and insects with synthetic payloads, researchers are creating living biohybrid miniature robots that self-fuel, self-repair, and navigate environments that would paralyze a rigid silicon chip.

NewsFoxes and birds could be ‘early warning system’ to survey spread of antibiotic resistance into ecosystems
Wildlife monitoring could alert us to the spread of highly antibiotic resistant bacteria into unexposed ecosystems, highlighting a potential public health strategy.

NewsColor test ‘sniffs out’ dangerous staph strains fast
Researchers have developed a rapid colour-changing test that can distinguish between different strains of golden staph, including those likely to be virulent and antibiotic resistant.

NewsAncient tooth reveals the bacterium responsible for scarlet fever was not introduced to the Americas by Europeans
A research team has identified the Streptococcus pyogenes bacterium in a pre-Columbian Bolivian mummy and, for the first time, reconstructed the genome of this centuries-old pathogen.

NewsResearchers synthesize photosynthetic molecule found in bacteria
Researchers have successfully synthesized bacteriochlorophyll a, a photosynthetic pigment found in bacteria which absorbs infrared light. The work represents the first chemical synthesis of this molecule and could give scientists deeper insights into photosynthetic function and photosynthetic energy.
