NewsGolden Gate method enables rapid, fully-synthetic engineering of therapeutically relevant bacteriophages
Researchers have described the first fully synthetic bacteriophage engineering system for Pseudomonas aeruginosa. In this method, researchers engineer bacteriophages synthetically using sequence data rather than bacteriophage isolates.

NewsReconstructing nature’s oxindole factory: yeast-based biosynthesis of medicinal indole alkaloids
By identifying four key enzymes from a North American plant and reconstituting them in yeast, scientists have achieved complete de novo biosynthesis of complex oxindole molecules that are difficult to obtain from plants or chemical synthesis.

NewsValneva provides update on Chikungunya vaccine IXCHIQ®
Valneva SE has announced that the company has decided to voluntarily withdraw the biologics license application (BLA) and Investigational New Drug (IND) application for its chikungunya vaccine, IXCHIQ® , in the United States, following suspension of the license by the FDA.

NewsShingles vaccine linked to slower biological aging in older adults
Shingles vaccination not only protects against the disease but may also contribute to slower biological aging in older adults, according to a new study.

News58% of patients affected by 2022 mpox outbreak report lasting physical symptoms
A cohort study found that more than half of those diagnosed with mpox during the 2022 outbreak still had lingering physical effects 11 to 18 months later.

NewsPregnant women hospitalized for COVID-19, and their newborns, have higher complication risk
When hospitalized for COVID-19, pregnant women — and their eventual newborn children — have a higher risk of complications. Research revealed that pregnant women were nearly 3.5 times more likely than non-pregnant women to require respiratory support when hospitalized for COVID-19.

NewsExploring metabolic noise opens new paths to better biomanufacturing
Engineers investigating fluctuating metabolic activity in microorganisms have developed tools to keep every microbial cell at peak productivity during biomanufacturing.

NewsCommercial water dispenser machines may contain more contamination than tap water
Water dispenser machines in commercial spaces may contain higher levels of microbial contamination if they aren’t cleaned regularly compared to the tap water sources supplying them that contain residual chlorine, according to a new study.

NewsShould younger and older people receive different treatments for the same infection?
Scientists find the mechanisms young mice use to fight sepsis become disadvantageous in older age, suggesting age-specific treatments may be necessary in ongoing antibiotic resistance crisis.

NewsGut bacteria molecule boosts lung cancer treatment response
Researchers have discovered a small compound produced naturally by gut bacteria that doubled the response to lung cancer immunotherapy treatment in mice and can now be made into a drug for testing in humans.

NewsSame moves, different terrain: How bacteria navigate complex environments without changing their playbook
New research shows that a diverse group of bacteria has learned how to use the same basic movements to move through a wide range of environments no matter how complex, from unconstrained fluids to densely packed soil and tissues.

NewsCorday Selden selected for the Oceanography Society Early Career Award
The Oceanography Society (TOS) has selected Dr. Corday Selden, an Assistant Professor at Rutgers University, as a recipient of the TOS Early Career Award, recognizing her outstanding early-career research contributions, leadership in ocean sciences, and exceptional promise for future impact in oceanography.

NewsMaternal microbiome compound may hold key to preventing liver disease
Children born to mothers who consume a high-fat, high-sugar diet during pregnancy and breastfeeding face a higher risk of developing fatty liver disease later in life. New research suggests that risk may be reduced by supplementing with a naturally occurring compound produced by healthy gut bacteria.

NewsA new study reveals how cholera virulence is activated
A new study provides a long-sought structural explanation of the regulatory cascade that allows Vibrio cholerae to colonize the human gut and produce the cholera toxin that causes life-threatening diarrhea.

NewsTB and HIV treatments are not enough for a full recovery
Existing treatments control TB and HIV, but the immune system does not revert to normal, helping explain why people living with HIV remain susceptible to infections and underscoring the need for immunotherapies.

NewsJeremy Horowitz selected for The Oceanography Society Early Career Award
The Oceanography Society (TOS) has selected Dr. Jeremy Horowitz as a recipient of the TOS Early Career Award, recognizing his outstanding early-career research contributions, impact, and promise for continued achievement in oceanography, along with his strong record of mentorship, outreach, and collaborative science.

NewsAboard the International Space Station, viruses and bacteria show atypical interplay
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth.

NewsWhy don’t antibiotic-making bacteria self-destruct?
Scientists discovered a promising new antibiotic in a soil sample. The molecule, lariocidin, is produced by the microbe Paenibacillus and shows broad activity against pathogenic bacteria. Now, the researchers report how Paenibacillus avoids harm by its own antibiotic.

NewsScientists observe infections by cancer-causing retroviruses in koalas as they occur
Scientists analysed the ongoing colonization by two retroviruses of the germline of koalas and resulting deaths from cancer in multi-generational pedigrees of over 100 koalas in US and European zoos. They calculated genetic risk scores (GRS) that can help guide koala breeding programs.

NewsBirding enthusiasts can help songbirds avoid salmonella epidemics
Biologists are developing a tool to predict when deadly salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right time.
