NewsBacteria gene discovery enhances key antibiotic production for farming and medicine
Monensin is a vital antibiotic used in agriculture and medicine. By analyzing the genome of Streptomyces cinnamonensis, the team discovered that specific genes (fadD, fadE, fadB, fadA) in the fatty acid degradation pathway significantly boost monensin synthesis.

NewsCan biodegradable mulch films harm soil health?
A new study validates the long-term ecological safety of biodegradable plastic mulch films in temperate maritime climates, breaking the traditional belief that “mulch films increase yield at the cost of soil fertility”.

NewsAntibiotic resistance predicts higher mortality risk in 17-year follow-up
A population-based study finds that in addition to antibiotic use, diet, sex, living environment, income level and certain gut bacteria are associated with a higher burden of resistance.

NewsEngineered microbe offers promising high-quality protein from methanol
Researchers have identified Methylophilus sp. HN238, a bacterium capable of efficiently converting methanol into high-quality protein. The protein meets WHO standards for quality, containing all 18 amino acids with essential amino acids making up 44.1% of the composition.

NewsResearchers uncover the antiviral potential of defensins
Scientists have discovered that certain defensins - tiny proteins with powerful antimicrobial potential - could block the virus that causes COVID-19 (SARS-CoV-2) from entering human cells.

NewsMicroalgae-based production of dietary protein using solar-derived formate
Researchers have established a robust Chlamydomonas reinhardtii cultivation system capable of rapid growth using formate as the carbon source. They achieved successful algal cultivation at 200 mM formate concentration - the highest level ever reported in microalgae systems.

NewsAI finds hundreds of potential antibiotics in snake and spider venom
Researchers used a deep-learning system to sift through a database of more than 40 million venom encrypted peptides (VEPs). In a matter of hours, the algorithm flagged 386 compounds with the molecular hallmarks of next-generation antibiotics.

NewsSwiss genome of the 1918 influenza virus reconstructed
Researchers have decoded the genome of the virus responsible for the 1918–1920 influenza pandemic in Switzerland, revealing that it had already developed key adaptations to humans at the outset of the deadliest influenza pandemic in history.

NewsReview suggests ending adult boosters for tetanus, diphtheria
The United States could safely drop tetanus and diphtheria booster shots for adults and save an estimated $1 billion a year, according to a new review. The safety and savings depend on maintaining strong childhood vaccination rates, researchers emphasized.

NewsNighttime pistachio snacking may reshape gut microbiome in prediabetic adults
A new study has determined that nighttime pistachio consumption affects gut bacteria in adults with prediabetes. The potential therapeutic implications of the findings may prove significant for people who are working to improve their metabolic health.

NewsH5N1 influenza outbreaks in US cattle likely triggered by ‘milk-stealing’ behavior of lactating cows
As of June 2025, H5N1 outbreaks have been reported on more than 1,070 dairy farms across 17 US states. Researchers have solved the mystery of how H5N1 virus enters the mammary glands of dairy cows, and provide a strategy on how to control the disease.

NewsUnprecedented acidification ahead for Hawaiian corals
A new study has revealed that unprecedented levels of ocean acidification are expected around the main Hawaiian Islands within the next three decades.

NewsTB bacteria play possum to evade vaccines
Scientists studied how the TB bacterium evades an immune system primed to destroy it. Their genetic study in mice reveals that TB bacteria can essentially play dead to outlast the immune response.

NewsResearchers engineer a microbial platform for efficient lutein production
The application of systems metabolic engineering strategies, and construction of an electron channeling system, has enabled the first gram-per-liter scale production of lutein from Corynebacterium glutamicum, providing a viable alternative to plant-derived lutein production.

NewsNew study finds evidence of hepatitis C virus in cells lining human brain
Observational studies of psychiatric diseases such as schizophrenia and bipolar disorder have long tied viral infections with behavioral symptoms in these disorders. Scientists have now found a connection in the form of hepatitis C virus in the human brain’s choroid plexus.

NewsEmerging viral threats combatted by a potent new dual lipid kinase inhibitor
Lipid kinases play a critical role in cell signalling and membrane trafficking by phosphorylating lipid molecules in the body. The inhibition of two of these lipid kinases, PIKfyve and PIP4K2C, could be beneficial in the treatment of diseases, particularly emerging viruses.

NewsEarly antibiotics alter immune function in infants- but a gut-derived molecule could help restore it
A new study has found that early-life exposure to antibiotics can impair an infant’s developing immune system, and that a naturally occurring metabolite may hold the key to reversing that damage.
