Expert guidelines for fungal endophthalmitis in the Asia-Pacific region

Fungal eye infections affect millions globally, with an especially high incidence in South and Southeast Asia.

Breakthrough platform reveals the choreography of mammalian transcription

Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins.

Poor lung gas exchange may help explain lingering brain symptoms in Long COVID

This study found that people with Long COVID more than two years after infection showed normal lung tests and brain structure, yet reported significant sleep and cognitive symptoms. Subtle correlations revealed that poorer lung gas exchange was linked with higher brain perfusion, worse sleep, and weaker executive function, suggesting a possible lung–brain connection.

Global Virus Network awards first pandemic preparedness research grants across four continents

The Global Virus Network (GVN) is pleased to announce that, for the first time, it is awarding pandemic preparedness research grants, totaling $160,000, to GVN scientists across four continents.

Expert panel recommends new antibiotic strategies for resistant Bordetella pertussis

Pertussis, or whooping cough, remains a highly contagious respiratory infection caused by Bordetella pertussis. Despite inclusion of pertussis vaccines in immunization programs since the 1970s, outbreaks have re-emerged globally due to waning immunity and bacterial evolution.

Breast cancer cells use a molecular switch to survive stress

Cells are regularly faced with environmental stresses that may damage or destroy them. To survive, they quickly adjust their gene expression to protect themselves.

Switching APOE4 to APOE2 in adult mice reduces Alzheimer’s pathology and improves memory

Replacing APOE4 with APOE2 in adult mice rapidly reshapes brain lipids and gene expression, even after development is complete. This switch, especially when targeted to astrocytes, reduces amyloid burden, dampens gliosis, and improves associative memory despite E2-like peripheral lipid risks.

Comprehensive kinase atlas reveals new insights into cell signaling and disease

The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme's "tail" called phosphorylation patterns.

CRISPR therapy shows promise against influenza in human lung chips

The Influenza A virus (IAV) has been the cause of six major flu pandemics, responsible for 50 to 100 million deaths globally.

What happens when microplastics reach the testes? Study shows autophagy and cell loss

Researchers found that microplastics from everyday plastic tableware accumulate in human semen and, although not linked to semen quality in the full cohort, were associated with altered sperm parameters in specific subgroups. Experimental models confirmed that 50 nm polystyrene particles trigger autophagy and apoptosis via the FOXA1/MAP3K1/p38 pathway, impairing sperm structure and function.

Innovative system accurately detects genetic mutations in the brain tumor within 25 minutes

A research team in Japan has developed an innovative system that can accurately detect genetic mutations in the brain tumor within just 25 minutes.

Azelastine nasal spray prevents COVID-19 and rhinovirus infections

Researchers discuss the effects of azelastine nasal spray on the rate of SARS-CoV-2 infection as compared to placebo.

Study shows dementia patients exposed to pollution had longer telomeres

Researchers studying a Swedish aging cohort found no overall link between air pollution and telomere shortening, a key marker of biological aging. Intriguingly, dementia patients exposed to higher pollution showed longer telomeres, though results were statistically non-significant.

Long COVID linked to heavier periods and symptom flare-ups during menstruation

Researchers found that long COVID is linked to heavier, longer, and more irregular bleeding without disrupting ovulation. Symptom severity also peaks around menstruation, likely driven by hormonal and immune changes.

Johns Hopkins team develops urine-based test for prostate cancer detection

Researchers at the Johns Hopkins Kimmel Cancer Center, Johns Hopkins All Children's Hospital and four other institutions have devised a novel method to test for prostate cancer using biomarkers present in urine, funded in part by the National Institutes of Health.

Concertgoers back detection dogs as practical COVID-19 screening tool in real-world trial

A feasibility study in Germany found that concertgoers strongly supported medical detection dogs for COVID-19 screening, with confidence rising after real-world use. The findings suggest canine testing could complement PCR and antigen tests, especially in large gatherings and high-traffic environments.
