New Imaging Workflow Tracks Nanoplastics Distribution in Neonatal Mouse Brains

Nanoplastics-plastic particles smaller than one micrometer-are generated through the degradation and abrasion of plastic products and are increasingly detected in food, drinking water, air, and biological tissues.

Scientists Discover How Heart Muscle Cells Remodel Actin Filaments

Biophysicists unraveled a mystery of how muscles form at the molecular level and how they maintain their function.

University of Oklahoma Study Uncovers Internal Recycling System in Photoreceptors

For decades, scientists believed that photoreceptors in the retina relied primarily on neighboring support cells, known as the retinal pigment epithelium (RPE), to remove waste. While the RPE is still responsible for clearing away the worn-out tips of photoreceptors each day, new findings from the University of Oklahoma reveal that photoreceptors also perform much of their own internal housekeeping.

Genomic Discoveries Reveal How Wild Plants Survive Extreme Altitude Shifts

A research team from the South China Botanical Garden, Chinese Academy of Sciences, has revealed the genomic basis of altitudinal adaptation in the widespread annual herb Capsella bursa-pastoris (L.) Medik. (shepherd's purse), a close relative of model plant Arabidopsis thaliana.

Wearable Microneedle Sensor Enables In Vivo Bioanalysis of Cardiac Biomarkers

Researchers developed a microneedle electrochemiluminescence device that measured cardiac troponins in interstitial fluid at 30-minute intervals and detected cTnI down to 21.3 fg/mL in artificial interstitial fluid. In 15 rats and 1 pig, researchers recorded biomarker trends broadly consistent with serum ELISA results, although the wired, single-target prototype has not been tested in humans.

Scientists Discover Molecular Mechanism Behind Red and Green Color Vision

Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green, or blue light.

Research Decodes How Gut Microbes Process Plant-Based Nutrients

Plant-based diets are good for you. They promote gut, immune, metabolic and cardiovascular health, in part by cultivating a diverse community of intestinal bacteria.

Deep-Learning Holography Detects Elusive Circulating Tumor Cells in Prostate Cancer

Researchers combined microfluidic enrichment, AI-assisted holography, and fluorescence profiling to identify circulating tumor cell candidates in 13 men with metastatic castration-resistant prostate cancer and 8 healthy donors. The platform found higher median candidate counts in patients, while nearly two-thirds of PSMA-positive candidates lacked EpCAM, suggesting EpCAM-dependent assays could miss some cells.

AI-Assisted Paper Test Measures Three Cardiac Biomarkers in 23 Minutes

Researchers developed an AI-assisted dual-mode paper assay that measures cTnI, CK-MB, and NT-proBNP from 50 µL of serum in 23 minutes. In single-site analytical validation, neural networks quantified the three biomarkers across distinct concentration ranges, supporting further development for multiplexed cardiac testing at the point of care.

FlatMux Imaging Platform Captures Live Brain Circuit Activity

The brain is a vast, densely interconnected network of neurons computing in parallel. Watching these computations unfold in real time could reveal how the brain processes sensation and guides behavior.

Scientists Discover Altered 3D Genome Structure in Alzheimer’s Brains

Researchers from Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington shed new light on Alzheimer's disease that could point to new directions for treatment.

Artificially Recreating C3 Effects Overcomes Resistance in Hard-to-Treat Tumors

An ancient molecule that existed long before the blood circulation system evolved, has been found to support cancer immunotherapy. Researchers at Nagoya University in Japan found that complement C3 protein acts inside tumors to prevent the accumulation of immunosuppressive cells, but only when produced inside the tumor.
