NewsScientists harness algae for a greener way to create functional gold nanoparticles
Researchers have pioneered a novel, sustainable method for synthesizing functionalized gold nanoparticles (AuNPs) using microalgae. This approach not only avoids the harsh chemicals used in conventional methods but also produces AuNPs that are more stable and less toxic to healthy cells.

NewsMissing links for rabies in Peru highlights global threats of health inequity
Researchers found that efforts to track dog-related rabies in poorer areas of Peru’s second largest city were lacking even though more dogs were found to have the disease there than in wealthier neighborhoods.

NewsWild grass offers new genetic clues to combat deadliest pathogen of wheat
A new study has identified Aegilops cylindrica, a wild grass closely related to wheat, as a powerful genetic reservoir for resistance against the devastating fungal pathogen Zymoseptoria tritici—the cause of Septoria tritici blotch (STB).

NewsEgypt becomes the seventh country in the Eastern Mediterranean Region to eliminate trachoma as a public health problem
The World Health Organization (WHO) today announced that Egypt has successfully eliminated trachoma as a public health problem, marking a historic public health milestone for the country and WHO’s Eastern Mediterranean Region (WHO EMR).

NewsHuman PARP gene could be novel target for viral diseases or immune-mediated disorders
Researchershave discovered a human gene, the protein PARP14, plays a role in regulating interferon, part of the body’s innate immune system. Their study could guide development of antiviral therapies for several groups of viral infection.

NewsMystery toxic algae regime change in Salem’s drinking water source
A long-term analysis shows that a major Oregon reservoir abruptly swapped one type of toxic algae for another midway through the 12-year study period, absent any obvious cause.

NewsRepurposed antibiotic shows promise against Central Nervous System Tuberculosis
Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have demonstrated that doxycycline, a commonly available and inexpensive antibiotic, can improve survival rates and neurological outcomes in Central Nervous System Tuberculosis (CNS-TB) in a preclinical non-human study. Published in the Journal of Neuroinflammation, the ...

NewsGrassland degradation reshapes relationship between biodiversity and ecosystem multifunctionality
Grassland degradation fundamentally reshapes how biodiversity supports ecosystem multifunctionality, shifting it from being plant-dominated to being mediated by soil microbes, according to a new study of alpine grassland on the Tibetan Plateau.

NewsBlood-based immunological signatures for extrapulmonary tuberculosis decoded
Scientists have deciphered the immunological properties of extrapulmonary tuberculosis (EPTB) in the blood of affected patients. The results may help to develop new targeted treatments and tests for this important disease.

NewsScientists reveal how cyanobacteria use ’sunscreen’ to adapt to climate
Using single particle spectroscopy, researchers revealed insights into how different types of photosynthetic bacteria can use a shared mechanism to protect themselves from too much sunlight.

NewsHow life first got moving: nature’s motor from billions of years ago
Research has cast light on the evolutionary origins of one of nature’s first motors, which developed 3.5 billion to 4 billion years ago to propel bacteria. Scientists have created the most comprehensive picture yet of the evolution of bacterial stators.

NewsScientists uncover global patterns and drivers of orchid mycorrhizal interactions
A global meta-analysis of orchid-fungal associations leads to a general conclusion: an orchid’s fungal community is driven more strongly by its ecophysiology and biogeography than by its phylogeny.

NewsCould tiny airborne plastics help viruses spread? Scientists warn of a hidden infection risk
While plastics are already recognized as a global environmental threat, a new commentary highlights that their microscopic airborne forms could also play a hidden role in human infection.

NewsPhages with fully-synthetic DNA can be edited gene by gene
Scientists have developed a method to construct bacteriophages with entirely synthetic genetic material, allowing researchers to add and subtract genes at will.

NewsNew drug target identified in fight against resistant infections
Researchers have identified new drug targets within a special repair system possessed by certain bacteria, known as Rtc, which enables them to counteract the effects of these antibiotics.

NewsHow are metabolism and cell growth connected? — A mystery over 180 years old
A research team has identified a novel principle in biology that mathematically explains why the growth of organisms slows as nutrients become more abundant—a phenomenon known as “the law of diminishing returns.”

NewsResearchers reveal novel mechanisms for decoding bacterial frequency modulation in signal processing
A study reveals the fundamental physical principles underlying bacterial FM signal processing, and demonstrated that FM decoding mechanisms enable bacteria to increase information entropy by approximately 2 bits compared to traditional AM in three-gene regulatory systems.

NewsSingle-cell insights reveal how HPV status reshapes penile tumor immunity
A study found that HPV-positive tumors in penile squamous cell carcinoma cases contained fewer proliferative macrophages and less exhausted CD8+ T cells, along with stronger chemokine signaling, revealing distinct immune remodeling associated with HPV infection.
