Study pinpoints key mechanism of brain aging

A new study by Stanford researchers reveals that declining proteostasis in the brain leads to increased protein aggregation, which is linked to neurodegenerative diseases. The findings were made using the turquoise killifish model, and shed light on the fundamental molecular principles of aging.

Protecting your beating heart

A team of researchers is using NCSA resources to simulate the long-term progression of atrial fibrillation, a type of irregular heartbeat. By modeling the heart's electrical activity, they have uncovered a vicious cycle where adaptations to maintain calcium balance lead to continued arrhythmias and eventually a permanent condition.

The clinical practice guideline update on adult sinusitis emphasizes patient education, shared decision-making, and evidence-based treatment options

The updated guideline emphasizes watchful waiting as the preferred approach for most bacterial sinus infections, while also providing clearer guidance on antibiotic use. The new recommendations aim to reduce unnecessary antibiotic prescriptions and promote effective symptomatic treatments.

MXene‑Ti3C2Tx‑based neuromorphic computing: physical mechanisms, performance enhancement, and cutting‑edge computing

This review highlights the potential of MXene-Ti3C2Tx as a universal platform for neuromorphic devices, offering sub-femtojoule synaptic events and nanosecond response times. The material enables flexible, multimodal, and biocompatible systems that classical silicon cannot match.

Pediatric investigation study identifies the optimal dose of methylprednisolone for treating severe mycoplasma pneumoniae pneumonia

Researchers conducted a randomized clinical trial to compare low- and high-dose methylprednisolone with azithromycin for treating severe Mycoplasma pneumoniae pneumonia. The study found that lower dose regimen of glucocorticoids is sufficient, equally effective, and safer than the high dose regimen.

Not all low-grade prostate cancers are low risk

A new study found that one in six men with low-grade prostate cancer (GG1) actually have intermediate- or high-risk cancer when other clinical features are considered. This suggests that relying on biopsy grade alone can lead to underestimating disease risk and misclassifying individuals who may benefit from definitive treatment.

Researchers reveal spatiotemporal coordination between pre-rRNA processing and nucleolar architecture

The study reveals a spatiotemporal separation in the processing of distinct pre-rRNAs within the nucleolus, contradicting traditional models. The findings suggest that small subunit (SSU) pre-rRNA is predominantly processed within the inner FC–PDFC regions, while large subunit (LSU) pre-rRNA matures gradually in the outer PDFC–GC regions.

Modified near-infrared annealing enabled rapid and homogeneous crystallization of perovskite films for efficient solar modules

Researchers have developed a modified near-infrared annealing process that turns blade-coated perovskite films into record-performing solar modules in just 20 seconds. The process slashes processing time by 30 times and halves energy use while delivering superior film quality.

CeO2-supported bi-layer Pt clusters enable efficient stable anti-Markovnikov alkene hydrosilylation

The research team developed a platinum bilayer cluster catalyst that achieves 99.9% silane conversion and 97.1% anti-Markovnikov selectivity, outperforming single-atom and nanoparticle catalysts. The catalyst's stable performance is attributed to strong silane adsorption and stable Pt-CeO2 interfacial bonding.

Light-based listening: Researchers develop a low-cost visual microphone

Researchers developed a low-cost visual microphone that listens with light instead of sound, capturing tiny vibrations on surfaces caused by sound waves and turning them into audible signals. The system uses single-pixel imaging to detect sound and can recover high-quality audio using everyday objects like paper cards and leaves.

Clownfish are not as homebound as we thought

A recent study challenges the idea that specialization with sea anemones explains clownfish diversification. Researchers identified 'eco-morphotypes' independent of host specialisation, with some species expending less energy for swimming and regularly swimming away from their anemones.
