NewsScientists discover how algae colonized corals, jumpstarting the growth of the world’s reefs
A research team questioned why algae are able to thrive inside the cells of coral? The finding could lead to new insights into why algae and coral are failing to thrive symbiotically and suggest ways to reestablish the connection and save the world’s reefs.

NewsResearchers propose new listeria labelling for smoked salmon and other ready-to-eat foods
Researchers are proposing a new labelling scheme designed to give consumers a better opportunity to choose ready-to-eat foods, such as smoked salmon and spiced pork roll, without risking infection with Listeria bacteria.

NewsNovel plasmid confers phosphorylation-driven streptomycin resistance in plant pathogen
The genetic basis underlying the unusually high-level streptomycin resistance observed in the field-derived strain TX-0702 of Clavibacter michiganensis has remined unknown until a new study identified a previously uncharacterized plasmid.

NewsThe case for fewer antibiotics in joint replacement surgery
Infections are a leading cause of joint replacement failures, however a new study suggests prescription of an extended courses of antibiotics after patients leave the hospital may not be needed.

NewsRice-grown chaga reveals genes behind valuable triterpenoids
New study links triterpenoid accumulation in Inonotus obliquus with rising expression of key biosynthetic genes, providing a genetic foundation for future work to improve sustainable production of Chaga-derived compounds.

NewsBreast milk gives certain gut bacteria a head start
Research shows that sugars in breast milk play an important role in the development of the gut microbiota, during weaning or transition from breast milk to solid food.

NewsBacteria can learn and form memories without a brain
Scientists have shown that bacteria can learn from past experiences, store memories across generations and adapt their behavior to changing environments.

NewsDrone index tracks wheat mildew
A new study addresses the need for rapid, field-scale monitoring of wheat powdery mildew in smallholder farms, where disease spread can be spatially uneven and difficult to capture through manual scouting alone.
-
NewsGrowing evidence that sugar substitutes disrupt gut health and metabolism
In a new review, researchers noted that artificial and other low-calorie sweeteners, compared to non-caloric controls such as water or placebo, raised fasting insulin and HbA1c, a marker of long-term blood sugar control, and showed a trend toward worsening insulin sensitivity.

NewsBiologists uncover a molecular mechanism that helps bacteria spread antibiotic resistance genes
A new study reveals the molecular mechanism behind one of the most powerful mechanical actions in all of biology, the reeling in of tiny surface fibers called type IV pili.

NewsScientists solve decades-old mystery of how malaria parasites invade human cells
Researchers have caught the malaria parasite’s moving junction in the act, obtainingg the first high-resolution view of its three-dimensional structure. It turns out to be a molecular machine that actively remodels the host cell’s membrane to help the parasite force its way inside.

ArticleCOVID-19 vaccine boosters may help protect against future animal coronaviruses
COVID-19 vaccine boosters not only protect against SARS‑CoV‑2 but may also help protect against some future coronaviruses that risk spreading from animals to humans, researchers have shown.

NewsExtreme droughts in the rainforest reduce important feedback between soil and atmosphere
The El Niño drought and heat suppress the capacity of the Amazon rainforest soil to absorb isoprene by a factor of four, while boosting its amount around the forest canopy.
-
NewsA non-toxic guard against Lyme disease could soon be an everyday purchase
Rather than vaccinating people or pets against Lyme disease, researchers are targeting the “reservoir hosts” — small mammals like squirrels, chipmunks and white-footed mice — that naturally carry the bacterium and pass it to ticks.
-
NewsNew evolution platform creates tougher yeast for sustainable biomanufacturing
Researchers have now developed a powerful new tool that accelerates microbial evolution. Their study introduces RAMPAGE, a programmable system that continuously generates genetic diversity across the genome of the industrial yeast P. pastoris.

NewsActinobacteria TFDB: a new comprehensive resource for transcription factor research in actinobacteria
Actinobacteria are a major source of bioactive natural products and exhibit an unusually high transcription factor (TF) abundance. A new study reports the development of Actinobacteria Transcription Factor Database integrating 629 TFs from 25 representative species.

NewsCommon probiotic ingredient turns immune cells into tumor killers
A probiotic bacterium secretes mannose—that significantly suppresses melanoma growth in mice by activating the body’s own immune defenses. Mannose enters CD8⁺ T cells through glucose transporters and inhibits a key protein called YAP1, which normally restrains T-cell killing power.
-
NewsGut microbiome: The hidden architect of liver cancer immunotherapy response
A comprehensive review synthesizes current advances linking gut bacteria to immunotherapy outcomes in hepatocellular carcinoma (HCC), the most common type of primary liver cancer.

NewsBillions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
A comprehensive review brings together global evidence to strengthen public trust and counter misinformation as mRNA vaccines expand to prevent and treat more diseases.

NewsMicrobe–fertilizer pair cuts greenhouse soil emissions
A new study shows that inoculating organic fertilizers with denitrifying bacterium, especially when paired with mushroom residue organic manure, reduces N₂O emissions by reshaping the soil microbiome.
