NewsThe only critically endangered crane went from 140 to 5,616 — but the numbers aren’t the full picture
A perspective proposes scoring conservation by six dimensions of population health after finding antibiotic residues and 62 microplastic particles per gram in crane droppings at Poyang Lake.

NewsCARB-X funds UNSW Sydney to develop novel antibiotic targeting drug-resistant Gram negative bacterial infections
Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) is awarding US$853k to UNSW Sydney to support the development of synthetic darobactin analogues, a new class of antibiotic designed to kill multidrug-resistant Gram-negative bacteria.

NewsResistant bacteria are favored in hospital sewers – responsible antibiotics identified
A study examined sewer systems and wastewater from hospitals and municipal treatment plants in eight Swedish cities. Sewage from all ten hospitals promoted antibiotic-resistant bacteria, while no such effects were found after exposure to sewage from the corresponding municipal treatment plants.

NewsAmino acid boosts last-resort antibiotic’s effectiveness
Colistin is a powerful, last-resort antibiotic for bacterial infections, but the number of colistin-resistant infections is growing. New research suggests that adding L-arginine, an amino acid, to colistin may overcome resistance. Lab and mouse studies show promising results, but more tests are needed before the strategy can help people.

NewsOne in four Americans have exaggerated or made up symptoms to try to get antibiotics
More than a quarter of Americans have exaggerated or made up symptoms to try to get antibiotics from their doctor, either for themselves or for their children, a new study has found.

NewsAntibiotic use from childhood linked to higher odds of IBS in young adulthood
Antibiotic use from childhood through early adulthood was associated with higher odds of irritable bowel syndrome (IBS) at age 24, with the odds increasing as the number of antibiotic prescriptions rose, according to a new study.

NewsGut microbes don’t just train the immune system—they keep it in shape
Immune maturation has long been viewed as a developmental milestone tied to weaning, when pups are first exposed to a flood of dietary antigens and colonizing microbes. A study now suggests that in mice, the immune competence established after weaning is not self-sustaining—it must be continuously maintained by signals from the commensal microbiota.

News‘Molecular movie’ captures penicillin being built atom by atom
Scientists have captured the formation of penicillin’s defining β-lactam ring in unprecedented detail, revealing fleeting chemical steps that had remained hidden for decades. Using ultrafast X-ray imaging, the researchers built a molecular movie of the reaction that could help guide future antibiotic and enzyme design.

NewsA natural compound takes aim at C. difficile while sparing the gut microbiome
Researchers identify argyrin B, a promising natural compound that targets the bacterium behind dangerous intestinal infections while leaving beneficial gut microbes largely unharmed. The discovery could pave the way for new treatments with fewer relapses and side effects.
-
NewsA newly discovered membrane defence help explain antibiotic resistance in Pseudomonas aeruginosa
Scientists have uncovered how Pseudomonas aeruginosa, a major multidrug-resistant superbug, helps block antibiotics from entering its cells. The study identifies two proteins that act like plugs inside a membrane channel, revealing a potential new target for treatments designed to weaken bacterial defenses.

NewsStaphylococcus aureus is highly resistant and virulent in milk
Staphylococcus aureus is frequently found in human and veterinary infections. Its ability to withstand antibiotic treatment makes it a major clinical challenge. To better understand the factors underlying this resistance, the scientists investigated the growth of the bacterium in two environments relevant to infection: milk and serum.

NewsSugar amplifies damage done to gut health by antibiotics
Eating sweets while taking antibiotics may worsen the harm done by the drugs to the normal community of bacteria in the gut, a new study has found. The study of hospitalized cancer patients found an additional 21% reduction in the variety of helpful bacterial species present for every 100 grams of sugar consumed in the 48 hours before treatment.

NewsA new mechanism of action against an old enemy
Researchers identified corramycin as a promising candidate against Mycobacterium tuberculosis. In the laboratory, the natural compound is effective against various forms of the tuberculosis pathogen, including strains from clinical samples that are already resistant to common antibiotics.
-
NewsCommonly used cancer drugs boost MRSA antibiotics – new research
Scientists tested five anti-cancer drugs and revealed that four of them helped penicillin-type antibiotics to kill MRSA. These drugs interfere with the bacteria’s ability to make DNA, making the bacteria more vulnerable to the antibiotics.

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.
-
NewsTuberculosis transmission may hold the key to prevention
Scientists have discovered the specific mechanisms that enable the bacteria responsible for tuberculosis to not only survive drying but also to generate mutations linked to antibiotic resistance.

NewsEmergence of Stutzerimonas nitrititolerans co-carrying carbapenem and tigecycline resistance from geese in China
Researchers have found strains of Stutzerimonas nitrititolerans with resistance to meropenem and reduced susceptibility to tigecycline in geese feces in Yangzhou, China.
-
NewsNew discovery could help scientists fight deadly fungal infections
Researchers have discovered that the bacterial antibiotic ‘gladiolin’ can disarm Candida albicans, one of the leading causes of life-threatening fungal infections, opening new avenues for developing life-saving treatments.
-
NewsDevelopment of dual-action compounds to fight cancer and infections
Researchers have developed new hybrid compounds that simultaneously reduce the viability of aggressive cancer cells and inhibit the growth of certain bacteria and fungi.
