NewsHidden microbial ecosystems inside tumors reveal new frontiers for cancer treatment
Far from being sterile, tumors host complex communities of bacteria, fungi, and viruses that actively influence disease progression, immune responses, and treatment outcomes. A review highlights how these microbial populations function as key regulators of tumor immunity.

NewsA lesser-known SARS-CoV-2 protein may offer clues to long COVID symptoms
A new study describes a previously unrecognized way the SARS-CoV-2 nucleocapsid protein can push the immune system into dangerous overdrive.

NewsWidely used early warning score may help guide the urgency of antibiotic treatment for suspected sepsis
Large cohort study suggests the National Early Warning Score (NEWS2) may provide a more comprehensive framework than current guidance for determining which patients with suspected sepsis benefit from immediate antibiotics.

NewsResearchers find evidence for two independent origins of life
Researchers retraced the origin of enzymes during life’s earliest divergence into bacteria and archaea, and found evidence for two independent origins of life for free-living cells.

NewsNew vaccine strategy protects against chikungunya and could become a platform for combating other diseases
Researchers created a genetically modified version of the Chikungunya virus that replicates only once, yet still trains the immune system to defend itself without causing disease.

NewsNight shift work linked to a higher risk of long COVID
People working night shifts were nearly twice as likely to develop long COVID, while chronic insomnia further increased the risk, according to a study based on the COVICAT cohort.

NewsNo-tillage and microbial fertilizer work together to build carbon in nutrient-poor albic soils
A field study in northeastern China shows that combining reduced soil disturbance with microbial organic fertilizer can increase soil organic carbon across both surface and deeper soil layers.

NewsAdults living with HIV are at high risk for diabetes. Here’s why.
A new study helps explain why people with HIV remain at elevated risk for type 2 diabetes despite effective suppression of the virus with modern medications.

NewsU.S. disease tracker launches to strengthen monitoring of vaccine-preventable diseases
A new website will track the spread of vaccine-preventable diseases across the United States to offer the public, the media, healthcare providers, public health officials, and policymakers reliable and visual information about current disease trends.

NewsChemolithoautotrophic breakthrough: bacteria converts CO2 into p-coumaric acid without light
p-Coumaric acid is a critical building block for pharmaceuticals, cosmetics, and functional foods. A new study research leverages C. necator H16’s ability to use H2 as an energy source and CO2 as its sole carbon source.

NewsMXene-based hydrogel disrupts bacterial biofilms and reprograms immune cell metabolism to reverse bone resorption in periodontitis
Periodontitis treatment not only requires effectively disrupting bacterial biofilms but also reshaping the local immune metabolic microenvironment to fundamentally break the vicious cycle of “infection-inflammation-bone resorption.”

NewsHow do vaccine conspiracy beliefs develop?
Researchers analyzed five years of longitudinal panel survey data collected between 2020 and 2024 and examined how vaccine-related conspiracy beliefs were associated with media skepticism during the COVID-19 pandemic.

NewsLemurs fall prey to human herpes virus
A new study marks the first time researchers have been able to confirm human herpesvirus in lemurs via a molecular analysis, outlining the cases of four privately owned animals who died from the illness.

NewsBiofortified millet benefits toddlers without supplement side effects
Toddlers who ate iron- and zinc-biofortified pearl millet for nine months did not experience adverse effects typically associated with increased iron intake and developed gut microbiomes with distinct and potentially beneficial changes.
-
NewsFirst immune pathway discovered that stops a normally harmless fungus spreading through the body and causing deadly disease
An immune pathway has been discovered which prevents a normally harmless fungus developing into a fatal infection.
-
NewsSoil properties determine how farmland microbes release nitrous oxide
A study of agricultural soils reports that physicochemical constraints and microbial functional differences jointly regulate denitrification, causing carbon and nitrogen inputs to alter N₂O and N₂ production differently among soil types.
-
NewsDo human noroviruses also switch their shape?
Researchers investigating whether human norovirus undergoes conformational changes in response to environmental condition successfully produced virus-like particles (VLPs) of the human norovirus GII.3 strain and determined their structures.

NewsHidden genome variation steers growth in fungus-dependent orchid
A chromosome-level genome and population survey of the fungus-dependent orchid Gastrodia elata has revealed how hidden genetic differences may shape growth, tuber form, and carbohydrate allocation.
-
NewsWarming reshapes how nitrogen is stored and lost in flooded rice soils
A three-year field experiment shows that higher temperatures accelerate nitrogen cycling while promoting retention in protected soil pools.

NewsSilencing a fungal wall protein cuts powdery mildew on melon leaves
Powdery mildew fungi survive on living plants behind a cell wall that provides both structural support and a shield against host immunity. Researchers have now identified the fungal cell wall assembly protein ECM33 as a weak point in that defense.
